Twitter beefs up security safeguards after recent attacks

(Reuters) - Twitter Inc began introducing new technology on Wednesday to shore up security for users, responding to a spate of recent attacks on prominent accounts including those owned by the Associated Press and Financial Times.

Twitter said in a blog post it has begun to introduce "login verification," a form of two-factor authentication in security industry parlance. The feature asks users to confirm their identity after a typical log-in, by sending a six-digit code to smartphones that must then be typed in to complete a sign-on.

The microblogging service, considered one of the most important communications platforms today, has not done enough to help protect users' accounts, critics say. That criticism intensified after a fake tweet sent from the AP's account in April about a non-existent White House explosion briefly roiled U.S. financial markets.

"There's a second check to make sure it's really you," the company said on its official blog.

Repeated hacking incidents have raised questions about Twitter's credibility and reliability just as it is beginning to assume a central role in a fast-changing media landscape, with the volume of tweets rising to more than 400 million a day.

Advance in nanotech gene sequencing technique

Tuesday, May 21, 2013

The allure of personalized medicine has made new, more efficient ways of sequencing genes a top research priority. One promising technique involves reading DNA bases using changes in electrical current as they are threaded through a nanoscopic hole.

Now, a team led by University of Pennsylvania physicists has used solid-state nanopores to differentiate single-stranded DNA molecules containing sequences of a single repeating base.

The study was led by Marija Drndi?, an associate professor in the Department of Physics and Astronomy in the School of Arts and Sciences, along with graduate students Kimberly Venta and Matthew Puster and post-doctoral researchers Gabriel Shemer, Julio A. Rodriguez-Manzo and Adrian Balan. They collaborated with assistant professor Jacob K. Rosenstein of Brown University and professor Kenneth L. Shepard of Columbia University.

Their results were published in the journal ACS Nano.

In this technique, known as DNA translocation measurements, strands of DNA in a salt solution are driven through an opening in a membrane by an applied electric field. As each base of the strand passes through the pore, it blocks some ions from passing through at the same time; amplifiers attached to the nanopore chip can register the resulting drop in electrical current. Because each base has a different size, researchers hope to use this data to infer the order of the bases as the strand passes through. The differences in base sizes are so small, however, that the proportions of both the nanopores and membranes need to be close those of the DNA strands themselves ? a major challenge.

The nanopore devices closest to being a commercially viable option for sequencing are made out of protein pores and lipid bilayers. Such protein pores have desirable proportions, but the lipid bilayer membranes in which they are inserted are akin to a film of soap, which leaves much to be desired in terms of durability and robustness.

Solid-state nanopore devices, which are made of thin solid-state membranes, offer advantages over their biological counterparts ? they can be more easily shipped and integrated with other electronics ? but the basic demonstrations of proof-of-principle sensitivity to different DNA bases have been slower.

"While biological nanopores have shown the ability to resolve single nucleotides, solid-state alternatives have lagged due to two challenges of actually manufacturing the right-sized pores and achieving high-signal, low-noise and high-bandwidth measurements," Drndi? said. "We're attacking those two challenges here."

Because the mechanism by which the nanopore differentiate between one type of base and another is by the amount of the pore's aperture that is blocked, the smaller a pore's diameter, the more accurate it is. For the nanopore to be effective at determining a sequence of bases, its diameter must approach the diameter of the DNA and its thickness must approach that of the space between one base and the next, or about 0.3 nanometers.

To get solid-state nanopores and membranes in these tiny proportions, researchers, including Drndi?'s group, are investigating cutting-edge materials, such as graphene. A single layer of carbon atoms in a hexagonal lattice, graphene membranes can be made a little as about 0.5 nanometers thick but have their own disadvantages to be addressed. For example, the material itself is hydrophobic, making it more difficult to pass strands of DNA through them.

In this experiment, Drndi? and her colleagues worked with a different material ? silicon nitride ? rather than attempting to craft single-atom-thick graphene membranes for nanopores. Treated silicon nitride is hydrophilic and has readily allowed DNA translocations, as measured by many other researchers during the last decade. And while their membrane is thicker, about 5 nanometers, silicon nitride pores can also approach graphene in terms of thinness due to the way they are manufactured.

"The way we make the nanopores in silicon nitride makes them taper off, so that the effective thickness is about a third of the rest of the membrane," Drndi? said.

Drndi? and her colleagues tested their silicon nitride nanopore on homopolymers, or single strands of DNA with sequences that consist of only one base repeated several times. The researchers were able to make distinct measurements for three of the four bases: adenine, cytosine and thymine. They did not attempt to measure guanine as homopolymers made with that base bind back on themselves, making it more difficult to pass them through the nanopores.

"We show that these small pores are sensitive to the base content," Drndi? said, "and we saw these results in pores with diameters between 1 and 2 nanometers, which is actually encouraging because it suggests some manufacturing variability may be okay."

Kinect Is Going To Watch How You Browse, Not Just What You Buy

There are endless metrics a store has access to when it comes to when, what, and who is buying merchandise. But surprisingly, there's not a heck of a lot of data on why a customer decides not to buy something. So Fujitsu is hoping its new Kinect-based research tool provides more insight into how customers browse, and why they may decide against a purchase.

The system obviously can't tell what a customer is thinking. But through detailed analysis of their body language and how they respond to a given item, or multiple items, stores will get a bit of insight into their customers' decision making processes. And this in turn might help the store better display, or provide more information on a given product that could help further influence a customer's final purchase decision. [DigInfo TV]

New Xbox: What?s Better, What?s Missing

?

Eight years after the debut of the Xbox 360, Microsoft has announced the Xbox One.? While it?s no quantum leap forward in gaming, it is attempting to tackle one of the biggest problems we face in our living rooms: a fractured landscape of devices that don?t play nicely together and require WAY too many remotes.??

Xbox One Specs

??????8 times the computing power of the previous Xbox 360

??????500 GB Hard Drive

??????8 GB Memory

??????Built-in Blu-ray DVD player

??????Kinect will come standard with every Xbox One

??????Kinect redesign with larger field of view, 1080p HD Camera, enhanced gesture recognition, and improved array microphones for voice control

??????Gaming Controller redesign: more distinct d-pad design, tactile feedback (rumble) ?Impulse Triggers? and Wi-Fi Direct connectivity to the console.

Gaming or Entertainment Breakthrough?

The new Xbox One represents an upgrade rather than an overhaul on physical design, internal horsepower, and social connectivity. But it is making an innovative play for entertainment dominance.?

The One looks like a TiVo or set top box. It has HDMI in and out, so it will take the HD input from your cable or satellite box, combine that with the One?s built-in Blu-ray DVD player, an Internet connection and, of course, game play to overlay and switch quickly between entertainment options.You can watch a live sporting event while checking your fantasy stats online.You can play a game and Skype.? You can watch a Blu-ray and check Facebook. This combined use on one screen is what sets the Xbox One apart from other consoles and entertainment devices.

Cable Box Compatibility

The promise is that you can do all those things on one screen without switching inputs and using one remote. But that mandates the Xbox One play nice-nice with all the cable and satellite boxes ? which is no small feat. ?The demo at the Xbox One debut used a Comcast cable connection, but it?s unclear which providers will sign up to partner with Microsoft on the integration.

There is an infrared out jack on the Xbox One, which may be the default solution to remotely control 3rd party set top boxes,but the proof of this bid to take over the living room will have to be field tested extensively to see how it plays in the real world.

Voice and Gesture Control

Because every Xbox One will ship with a Kinect motion gaming controller, gesture is built into the controls for both games and entertainment. ?Swipe up? to scroll and ?grab and pan? were both demonstrated to control screens and inputs. The Kinect will also have improved microphone arrays for improved voice control.?

If the Xbox One becomes your pass-through hub for entertainment, it will need to be ?always on.? If you?ve ever forgotten to turn your Xbox 360 off, you know this is an issue because it sounds like a blender;it?s LOUD. So Microsoft execs made a distinct point that the Xbox One is ?nearly silent.?

Game play

The presentation of the Xbox One focused on entertainment for the first 30ish minutes, and gamers were screaming via Twitter and live blogs about Microsoft?s lack of attention to the actual game play. But when Microsoft did turn the focus to gaming, they highlighted iterative changes to the hardware: larger hard drive (500 GB), more memory (8 GB), improved controller (smaller battery, better d-pad, Wi-Fi Direct connection to the console). When they finally turned to specific games and graphics improvements, culminating in the announcement of the next Call of Duty franchise (Call of Duty: Ghosts), Activision highlighted the improved facial nuances, more lifelike skin of characters, and even the fur and expressions of the COD dog.

Call of Duty: Ghosts will debut on the Xbox One, but is not necessarily exclusive to the Xbox One. ?And comparing the graphics demo for the Xbox One to the Playstation 4 graphics demo ?(scroll to 1:18:00 in the linked video), you can see that the entire industry is moving forward in real-time rendered graphics, and this distinction between the platforms seems less relevant than the distinction between their overall entertainment features.

Rumors That Didn?t Pan Out

Has to be connected to the Internet to function?

Microsoft has confirmed that local games will play when offline. You don?t need to be always connected to play but you do need an Internet connection. One touted Internet-based aspect of the new gaming system is that developers will be able to use Microsoft's Azure cloud computing service and the company has increased their cloud computing servers from 15,000 to a seriously robust 300,000 servers.

Will not play used or previously owned games?

Microsoft has confirmed the XBOX One will play previously-owned or shared games

Kinect will recognize facial expressions like smiling or frowning?

No mention of that in the presentation although it?s pretty cool that in fitness games Kinect can read your heart-rate and now has increased recognition of wrist and shoulder movement.

Projected games or augmented reality glasses that work with gesture control?

It sounded too good to be true but this rumor based on patents was not mention of those features.

Will play Xbox 360 games?

Sadly it won?t. Microsoft spokespeople have confirmed that the Xbox One will not be backwards compatible with Xbox 360 games. There is a possibility of emulators or cloud-based versions of previous games.

Unanswered Questions

Price? Not mentioned but $399 to $499 seems to be the likely range

Release Date? ?Sometime this year.?

How many models? Not mentioned, but to stay attractive to casual gamers and entertainment minded users a lower end model (smaller hard drive, fewer gaming features) would seem to be a sure thing.

Cable and satellite provider compatibility? Not disclosed.

Other titles? Shown at the Xbox One launch we saw new titles from EA Sports: FIFA, Madden, NBA Live?and?UFC. A peek at Forza Motorsports 5, Quantum Break, from Remedy, and Call of Duty: Ghosts. Microsoft promises more title info at the E3 gaming conference in June.

ASUS Zenbook Infinity Ultrabook to appear at Computex 2013 with Gorilla Glass 3 lid

ASUS' Transformer Book hybrid may have just graduated from our review testing, but the company already has a new product to tempt you. The Zenbook Infinity will be the "world's first Ultrabook with a lid made form Corning Gorilla Glass 3" and will be revealed in full at Taipei's Computex 2013 in a few weeks. It'll measure in at just 15.5mm thick -- a full 14 percent thinner than previous Zenbooks. Next-generation Gorilla Glass will cover the outer lid and the keyboard surround, although you can expect to see that familiar concentric circle pattern beneath that protection. ASUS says the Ultrabook will launch Q3 2013, but we can expect to see the full specs before then.

Kepler epitaph? Eight most intriguing finds of troubled telescope.

Kepler, the space telescope designed to help us find other Earth-like planets, is on the fritz. Scientists hope they will be able to fix it remotely, but if they can't, its brief, brilliant career could be over. Since it began operations in 2009, peering continuously at the same field of 145,000 stars in the constellations Cygnus and Lyra, it has found more than 2,700 planet-candidates. Here are eight of its most remarkable discoveries.?

- Mark Sappenfield,?Staff writer

1. Kepler-22b: Goldilocks planet

Kepler has made an array of stunning discoveries ? from oddball solar systems to sun-scorched planets that orbit their stars in less than an Earth day. But Kepler-22b was the first discovery that truly validated the mission.

The goal for Kepler has always been to find Earth-mass planets orbiting sun-like stars at Earth-like distances. In other words, to find Earth's cosmic twins. Kepler-22b was perhaps a bit more like a big brother ? it's larger than Earth ? but its discovery was proof that Kepler was on the right track.

Scientists announced the discovery of Kepler-22b in December 2011. It was smack dab in the middle of its star's so-called habitable zone ? the "Goldilocks zone" close enough to allow water to be liquid but far enough to ensure that it didn't burn off. Kepler-22b orbits its sun once every 290 days. Moreover, its sun is the same G-type star as our sun, though slightly smaller and cooler.

The planet itself has a radius 2.4 times larger than Earth. Scientists are not sure about the composition of the planet, but some have suggested it could be a mini-Neptune with a global ocean and a rocky core. If it has an atmosphere, the temperature could be 72 degrees F.

"It's so exciting to imagine the possibilities," Natalie Batalha, the Kepler deputy science chief, told the Associated Press in 2011. Floating on that "world completely covered in water" could be like being on an Earth ocean, and "it's not beyond the realm of possibility that life could exist in such an ocean."

Yahoo agrees to buy Tumblr for $1.1 billion cash

AP

Yahoo's board has agreed to buy Tumblr for $1.1 billion cash. Yahoo CEO Marissa Mayer has acquired several social media sites, presumably to attract a younger audience.

Yahoo and Tumblr made their wedding vows Monday with the stumbling Web search giant publicly announcing its promise not to "screw up" the relationship.

Yahoo confirmed it will buy the blogging website for $1.1 billion cash, in a bold move to make itself more relevant amid the explosion in social media on the Internet.

It was old new media hooking up with new new media. Even as Yahoo's CEO Marissa Mayer took to social media to announce the deal, promising "not to screw it up," David Karp, the 26-year-old wunderkind who heads Tumblr celebrated the acquisition with a blog post that signed off with "F*** yeah, David."??

Perhaps trying to assuage Tumbler users who are concerned that Yahoo would irrevocably alter the blogging site's edgy image, Yahoo said Tumblr will operate independently as a separate business.

"David Karp will remain CEO. The product, service and brand will continue to be defined and developed separately with the same Tumblr irreverence, wit, and commitment to empower creators," the statement said.

Marissa Mayer's own Tumblr post showed some of that irreverence with a GIF that seemed to poke fun at all the worries about the deal. "Now panic and freak out," "Keep calm and carry on," "Yahoo," "Tumblr" the GIF said in successive, pastel-colored panels. Mayer also posted a tweet that had the Internet buzzing a bit with some mild ribbing.

Marissa Mayer tweets about the Yahoo deal to buy Tumblr for $1.1 billion.

"Before touching on how awesome this is, let me try to allay any concerns: We?re not turning purple. Our headquarters isn?t moving. Our team isn?t changing. Our roadmap isn?t changing. And our mission ? to empower creators to make their best work and get it in front of the audience they deserve ? certainly isn?t changing," Karp, who dropped out of high school at 15 to start the company, said in his blog post.

News of the deal was widely leaked Sunday. Talk of a deal began circulating Friday, after the Wall Street Journal's All Things D reported that the two companies had been in talks for several weeks.

Since Marissa Mayer became CEO at Yahoo, the company has acquired several companies that appeal to younger audiences, including Summly, Astrid and Jybe. Yahoo has also been rumored to be eyeing Hulu.

Observers say Mayer is making these deals to attract a younger audience.

LG to demo 5-inch unbreakable and flexible plastic OLED panel at SID

LG to demo 5inch flexible and unbreakable plastic OLED panel at SID 2013

LG's got quite a bit in store for us this week at SID's annual display exhibition in Vancouver. In addition to that 55-inch curved OLED TV we first heard about last month, the company will be demonstrating a very nifty 5-inch OLED panel. Created for mobile devices, the display is constructed of plastic, making it both flexible and unbreakable -- certainly a welcome quality when it comes to smartphone design.

Also on display will be 5- and 7-inch HD Oxide TFT panels. That first size features a bezel that's just 1mm wide, enabling a borderless frame when installed in smartphones. Both displays are lightweight and consume less power than their traditional equivalents. Finally, LG will have a 14-inch 2560x1440-pixel laptop panel on hand, along with LCDs designed for use in refrigerators and automotive dashboards. We'll be live from the SID show floor later this week -- check back for our hands-ons with all of these new LG panels, and quite a bit more.

Crazy ants vs. Fire ants: Who's winning? (+video)

Crazy ants are taking over areas once occupied by fire ants in the South. The sting of Crazy ants isn't as painful and migrate slowly. But Crazy ants multiply faster.

By Douglas Main,?LiveScience / May 18, 2013

Invasive fire ants have been a thorn in the sides of Southerners for years. But another invasive species, the so-called "crazy" ant ? that many describe as being worse ? has arrived and is displacing fire ants in several places.

Skip to next paragraph

' + google_ads[0].line2 + '
' + google_ads[0].line3 + '

'; } else if (google_ads.length > 1) { ad_unit += ''; } } document.getElementById("ad_unit").innerHTML += ad_unit; google_adnum += google_ads.length; return; } var google_adnum = 0; google_ad_client = "pub-6743622525202572"; google_ad_output = 'js'; google_max_num_ads = '1'; google_feedback = "on"; google_ad_type = "text"; // google_adtest = "on"; google_image_size = '230x105'; google_skip = '0'; // -->

"When you talk to folks who live in the invaded areas, they tell you they want their fire ants back," said Edward LeBrun, a researcher at the University of Texas at Austin, in a statement from the school. "Fire ants are in many ways very polite. They live in your yard. They form mounds and stay there, and they only interact with you if you step on their mound."

Crazy ants, on the other hand, "go everywhere," invading homes and nesting in walls and crawlspaces, even damaging electrical equipment by swarming inside appliances. [Image Gallery: Ants of the World]

A study published in the April issue of the journal Biological Invasions found that in areas infested with crazy ants, few to no fire ants were present. Exactly how they are able to outcompete fire ants is so far unknown. In areas with crazy ants, the researchers also found greatly diminished numbers of native ant species, according to the study.

Fire ants are known for their painful stings and have spread through the Southeast since arriving from South America in the 1930s. Crazy ants were first discovered in Houston in 2002, and they have already spread to coastal areas from Texas to Florida, according to the researchers. Although the "crazies" don't have as painful a sting as fire ants, they multiply in even greater numbers. They are also difficult to control since they don't eat the same poison baits as fire ants do, the statement noted.

Last year, the crazy ant species was identified as Nylanderia fulva, which hails from northern Argentina and southern Brazil, according to a 2012 study in PLOS ONE. It's also known as the tawny crazy ant and was previously named the Rasberry crazy ant after the exterminator Tom Rasberry, who first discovered it. The "crazy" moniker comes from the ant's quick, seemingly random movements.

Luckily, the crazy ant doesn't spread as quickly as the fire ant, advancing only 650 feet (200 meters) per year on its own, the release noted. Therefore, it's vital that people don't accidentally transport the ant, the prime method by which it has spread, according to the release.

Congress takes on the IRS scandal

By John Whitesides

WASHINGTON (Reuters) - A House of Representatives panel on Friday opens the first in a series of investigative hearings in Congress on the Internal Revenue Service's targeting of conservative groups for extra tax scrutiny, as the political storm over the scandal shifts to Capitol Hill.

Lawmakers from both parties are expected to grill the outgoing acting head of the agency, Steven Miller, and the Treasury Department inspector general for tax administration, J. Russell George, about the growing scandal that threatens to eclipse President Barack Obama's second-term agenda.

Miller was forced to resign on Wednesday, and Obama has since appeared in public twice to condemn the IRS's actions and promise full cooperation with three congressional investigations and a Justice Department probe.

Members of the House Ways and Means Committee are expected to press Miller at the hearing about why he did not disclose the practice of targeting conservative groups after learning about it in 2012, even when he was questioned about it by members of Congress.

Republicans, who have demanded more answers and angrily accused the administration of using government powers to target political foes, also are likely to question whether other groups or donors were singled out because of their political views, and whether the White House knew of the practice.

And as some Republicans use the scandal to raise questions about the IRS's ability to oversee parts of Obama's overhaul of the U.S. healthcare system, they may turn their attention to Sarah Hall Ingram, who led the agency's tax-exempt section when the targeting of conservative groups began and now is in charge of the IRS division handling healthcare.

Friday's hearing is scheduled to start at 9 a.m. EDT (1300 GMT).

"There are still far too many unanswered questions and until we know what truly happened, we cannot fully fix what is wrong," said Committee Chairman Dave Camp, a Republican from Michigan.

"The IRS has demonstrated a culture of cover up and has failed time and time again to be completely open and honest with the American people," Camp said.

George, who investigated the complaints against the IRS, issued a public report earlier this week that blamed ineffective management and bureaucratic confusion at the IRS for the agency's inappropriate targeting of conservative political groups for extra scrutiny when considering applications for tax-exempt status.

But George also could face vigorous questioning from Republicans about why he did not issue warnings about the practice earlier.

The political storm over the scandal has put Obama on the defensive at a time when he is negotiating with Republicans on a budget deal and trying to push a comprehensive immigration reform bill through Congress.

Two other committees, the House Oversight and Government Reform Committee and the Senate Finance Committee, also will hold IRS hearings next week.

'COMMON SENSE'

Representative Devin Nunes of California, a Republican member of the Ways and Means panel, said Friday's hearing will kick off a months-long investigative process. Nunes said he was suspicious of the tax agency's motives in targeting groups with names that included "Tea Party" or "Patriot."

Republican Representative Vern Buchanan, also on the panel, said he wants to know which IRS employees were involved and will press officials on larger issues plaguing the agency.

"The bottom line is they need to be fired in the next few days," the Florida Republican said on MSNBC's "Morning Joe" program on Friday.

Representative Sander Levin of Michigan, the top Democrat on the panel, said he was concerned that Republicans could turn the probe into a partisan witch hunt.

"There is a tendency to politicize. That would be a terrible mistake," Levin told reporters. "There are people who conjecture, who are trying to make connections. If there is no basis for it, that is also a mistake."

Camp and Levin sent the IRS a letter on Tuesday outlining the information they were seeking in the probe, including all documents relating to the targeting and any information on who knew about the practice and when they became aware of it.

The letter also asked for any other organizations singled out for their political views and the search terms used to find them, as well as all documents related to possible special reviews of groups whose missions involved Israel and all communication with the White House on the process.

Given the three congressional investigations and the Justice Department probe, Obama said, there was no need for a special prosecutor to look into the allegations.

"Between those investigations I think we're going to be able to figure out exactly what happened, who was involved, what went wrong, and we're going to be able to implement steps to fix it," Obama said at a Rose Garden news conference on Thursday.

Reading rock to understand how climate change unfolds

May 18, 2013 ? What happened the last time a vegetated Earth shifted from an extremely cold climate to desert-like conditions? And what does it tell us about climate change today?

John Isbell is on a quest to coax that information from the geology of the southernmost portions of the Earth. It won't be easy, because the last transition from "icehouse to greenhouse" occurred between 335 and 290 million years ago.

An expert in glaciation from the late Paleozoic Era, Isbell is challenging many assumptions about the way drastic climate change naturally unfolds. The research helps form the all-important baseline needed to predict what the added effects of human activity will bring.

Starting from 'deep freeze'

In the late Paleozoic, the modern continents were fused together into two huge land masses, with what is now the Southern Hemisphere, including Antarctica, called Gondwana. During the span of more than 60 million years, Gondwana shifted from a state of deep freeze into one so hot and dry it supported the appearance of reptiles. The change, however, didn't happen uniformly, Isbell says.

In fact, his research has shaken the common belief that Gondwana was covered by one massive sheet of ice which gradually and steadily melted away as conditions warmed. Isbell has found that at least 22 individual ice sheets were located in various places over the region. And the state of glaciation during the long warming period was marked by dramatic swings in temperature and atmospheric carbon dioxide (CO2) levels.

"There appears to be a direct association between low CO2 levels and glaciation," he says. "A lot of the changes in greenhouse gases and in a shrinking ice volume then are similar to what we're seeing today."

When the ice finally started disappearing, he says, it did so in the polar regions first and lingered in other parts of Gondwana with higher elevations. He attributes that to different conditions across Gondwana, such as mountain-building events, which would have preserved glaciers longer.

All about the carbon

To get an accurate picture of the range of conditions in the late Paleozoic, Isbell has traveled to Antarctica 16 times and has joined colleagues from around the world as part of an interdisciplinary team funded by the National Science Foundation. They have regularly gone to places where no one has ever walked on the rocks before.

One of his colleagues is paleoecologist Erik Gulbranson, who studies plant communities from the tail end of the Paleozoic and how they evolved in concert with the climatic changes. The information contained in fossil soil and plants, he says, can reveal a lot about carbon cycling, which is so central for applying the work to climate change today.

Documenting the particulars of how the carbon cycle behaved so long ago will allow them to answer questions like, 'What was the main force behind glaciation during the late Paleozoic? Was it mountain-building or climate change?'

Another characteristic of the late Paleozoic shift is that once the climate warmed significantly and atmospheric CO2 levels soared, the Earth's climate remained hot and dry for another 200 million years.

"These natural cycles are very long, and that's an important difference with what we're seeing with the contemporary global climate change," says Gulbranson. "Today, we're seeing change in greenhouse gas concentrations of CO2 on the order of centuries and decades."

Ancient trees and soil

In order to explain today's accelerated warming, Gulbranson's research illustrates that glaciers alone don't tell the whole story.

Many environmental factors leave an imprint on the carbon contained in tree trunks from this period. One of the things Gulbranson hypothesizes from his research in Antarctica is that an increase in deciduous trees occurred in higher latitudes during the late Paleozoic, driven by higher temperatures.

What he doesn't yet know is what the net effect was on the carbon cycle.

While trees soak in CO2 and give off oxygen, there are other environmental processes to consider, says Gulbranson. For example, CO2 emissions also come from soil as microbes speed up their consumption of organic matter with rising temperatures.

"The high latitudes today contain the largest amount of carbon locked up as organic material and permafrost soils on Earth today," he says. "It actually exceeds the amount of carbon you can measure in the rain forests. So what happens to that stockpile of carbon when you warm it and grow a forest over it is completely unknown."

Another unknown is whether the Northern Hemisphere during this time was also glaciated and warming. The pair are about to find out. With UWM backing, they will do field work in northeastern Russia this summer to study glacial deposits from the late Paleozoic.

The two scientists' work is complementary. Dating the rock is essential to pinpointing the rate of change in the carbon cycle, which would be the warning signal we could use today to indicate that nature is becoming dangerously unbalanced.

"If we figure out what happened with the glaciers," says Isbell, "and add it to what we know about other conditions -- we will be able to unlock the answers to climate change."

Canada abuzz over purported crack video of mayor

TORONTO (AP) ? A video purportedly of Toronto Mayor Rob Ford smoking crack has caused an uproar in Canada. Ford on Friday called the allegations "ridiculous."

The video has not been released publicly, and there is no way to verify whether it is authentic. Reports by gossip website Gawker and the Toronto Star said it was taken by a man who claimed he had sold crack to Ford. The Associated Press hasn't seen the video.

The conservative mayor of Canada's largest city emerged from his house on Friday and called the allegations "ridiculous."

Ford refused to take questions. In brief comments outside his office, he said it was "another story with respect to the Toronto Star going after me. And that's all I've got to say for now."

A lawyer for Ford didn't respond to messages seeking comment. Toronto police spokesman Mark Pugash said investigators were "monitoring the situation closely."

The Star reported that two reporters watched a video that appears to show Ford, sitting in a chair, inhaling from what appears to be a glass crack pipe. The Star said it did not obtain the video or pay to watch it.

The Star also reported that Ford made an anti-gay slur against the leader of the federal Liberal Party of Canada, Justin Trudeau.

Ford later appeared Friday at a previously scheduled ceremony marking International Day Against Homophobia.

Ford has been embroiled in controversies about his behavior since being elected in 2010, but these are the most serious allegations he's faced yet. The Toronto Star reported earlier this year that he was asked to leave a gala fundraiser for wounded Canadian soldiers because he appeared intoxicated.

He has also been accused of flouting conflict of interest rules and making obscene gestures at residents from his car, and he has had high-profile shouting altercations with a Toronto Transit worker as well as a Toronto Star reporter.

Ford, a city councilor for years, once said Toronto would be better off if it didn't accept more immigrants. Half of the city's population was born outside Canada.

Toronto deputy mayor Doug Holyday questioned the authenticity of the video, saying "video can be altered" and "drug dealers can't be trusted."

Holyday said he has not spoken to Ford or his staff since the allegations surfaced, but noted he still believes in the mayor "at this point."

"I wouldn't want my career or my credibility resting on the word of drug dealers," Holyday said.

The controversy has drawn comparisons to the 1990 arrest of then-Washington Mayor Marion Barry, who was videotaped smoking crack cocaine in a hotel room during an FBI sting operation.

Barry served six months in federal prison on a misdemeanor drug possession conviction and later won a fourth term as mayor in 1994.

Stocks flip between gains and losses; Cisco climbs

NEW YORK (AP) ? Cisco Systems led the Dow Jones industrial average slightly higher Thursday after the technology company reported higher sales. Mixed corporate earnings and economic reports kept the major stock indexes flipping between slight gains and losses.

Shortly after noon, the Dow was up 12 points at 15,288. The Standard & Poor's 500 index was up less than a point at 1,659.

The news on the economy Thursday wasn't encouraging. Applications for unemployment benefits rose last week, and manufacturing slowed in the mid-Atlantic region. The manufacturing report from the Philadelphia branch of the Federal Reserve sent bond prices up in morning trading and turned stocks lower, but not for long.

"We've been seeing a lot of that this year," said Scott King, an investment adviser at Unified Trust Co. in Lexington, Ky. "The news isn't great, yet the market holds tight."

Cisco jumped 13 percent, or $2.68, to $23.87. Cisco turned in quarterly results late Wednesday that beat analysts' expectations, with the help of better revenue from the U.S. and emerging markets.

The networking equipment company sells its routers, switches, software and services to corporate customers and government agencies around the world. As a result, Cisco's performance is often considered a gauge of how the technology industry is doing.

The Nasdaq rose 8 points to 3,479, a gain of 0.2 percent.

Wal-Mart fell 2 percent, the biggest drop among the 30 Dow stocks. The world's largest retailer turned in weaker sales and a dim forecast for profits. The company blamed bad weather and delayed tax refunds for earnings and sales that fell short of what analysts had expected. Wal-Mart's stock lost $1.68 to $78.11.

Companies have reported record quarterly profits this earnings season. Seven of every 10 in the S&P 500 have trumped analysts' earnings estimates, according to S&P Capital IQ. Earnings have climbed 5 percent over the year before.

But revenue has looked weak: six out of every 10 companies in the S&P 500 have missed forecasts, and revenue has edged up just 1 percent. Without higher sales, companies are getting more of their profits from laying off staff and other cost-cutting moves.

If the market is going to keep climbing this year, King said, sales will have to start rising. Analysts are looking for that to happen as economic growth gains strength later this year.

"It's hard to see how companies can squeeze more earnings growth out of cost savings," King said. "At some point, the economic numbers and revenue have to pick up."

The Philadelphia branch of the Federal Reserve reported that manufacturers in the region said business conditions have slumped this month. Orders for manufactured goods and shipments have been weak.

In Washington, the Labor Department reported that the number of Americans seeking unemployment benefits rose last week to 360,000. That suggests companies are laying more people off, just one week after applications for benefits hit a five-year low.

The yield on the 10-year Treasury note sank to 1.88 percent from 1.94 percent late Wednesday. It's a sign that traders are shifting money into low-risk investments like U.S. government debt.

Idaho man heads to court after terrorism arrest

BOISE, Idaho (AP) ? An Uzbekistan national living in Idaho has been arrested on federal charges that he gave support, cash and other resources to help a recognized terrorist group in his home country plan a terrorist attack.

Fazliddin Kurbanov, 30, is expected to make his first appearance in U.S. District Court Friday morning, one day after federal agents arrested him during a raid of his small Boise apartment.

Kurbanov was arrested after an extensive investigation into his activities in Idaho and Utah late last year and this year. A federal grand jury indictment charges Kurbanov with one count of conspiracy to provide material support to a foreign terrorist organization, and one count of conspiracy to provide material support to terrorists and possession of an unregistered explosive device.

A separate federal grand jury in Utah also returned an indictment charging Kurbanov with distributing information about explosives, bombs and weapons of mass destruction.

Wendy Olson, the U.S. attorney in Idaho, said Kurbanov is the only person charged, and any potential threat was contained by his arrest.

"He was closely monitored during the course of the investigation," she said. "The investigation has been underway for some time."

Olson declined to share any specifics of Kurbanov's alleged activities, including whether any potential terrorist threat or targets were domestic or abroad.

A statement from the U.S. attorney's office said Kurbanov is in the United States legally, but Olson declined to give specific details about his immigration status.

It was unclear when he moved to Idaho or the extent of his activities in Utah. An Idaho telephone number registered to Kurbanov has been disconnected.

The Idaho indictment alleges that between August 2012 and May 2013, Kurbanov knowingly conspired with others to provide support and resources, including computer software and money, to the Islamic Movement of Uzbekistan, which the U.S. has identified as a terrorist organization. The group's purpose is to overthrow the government of Uzbekistan, said David B. Barlow, U.S. attorney in Utah.

The alleged co-conspirators were not named.

In count two, the indictment alleges Kurbanov provided material support to terrorists, knowing that the help was to be used in preparation for a plot involving the use of a weapon of mass destruction.

The indictment also alleges that on Nov. 15, 2012, Kurbanov possessed an explosive device, consisting of a series of parts intended to be converted into a bomb. Those parts included a hollow hand grenade, a hobby fuse, aluminum powder, potassium nitrate and sulfur.

Meanwhile, in Utah, federal investigators said that for a 10-day period in January 2013, Kurbanov taught and demonstrated how to make an "explosive, destructive device, and weapon of mass destruction."

The grand jury alleges that Kurbanov provided written recipes for how to make improvised explosive devices and went on instructional shopping trips in Utah showing what items are necessary to buy to make the devices, Barlow said. Kurbanov also showed Internet videos on the topic, Barlow said.

The prosecutor declined to say whom Kurbanov took on the shopping trips in Utah but said that information will come out as the case moves through the courts.

The indictment from Utah also alleges that Kurbanov intended that the videos, recipes, instructions and shopping trips be used to make an explosive device for the "bombings of a place of public use, public transportation system, and infrastructure facility."

The arrest, Barlow said, shows that "there is no priority that is more important than the protection of the public and the prevention and disruption of alleged terrorist activities ? wherever they might occur."

Although the Islamic Movement of Uzbekistan started in the 1990s with the stated aim of overthrowing the Uzbek regime and establishing an Islamic government, its goals have expanded to creating a broader Central Asian caliphate.

The movement's fighters have a presence in Afghanistan's northern provinces and in Pakistan's Waziristan province. U.S. and Afghan officials say al-Qaeda has been building ties with the IMU.

Last year, an Uzbek named Ulugbek Kodirov was sentenced to a minimum 15 years in prison in Alabama for plotting to shoot President Barack Obama while on the campaign trial. Kodirov pleaded guilty, saying he was acting at the behest of the IMU.

According to Idaho's court system, Kurbanov has no criminal convictions but was ticketed for speeding violations twice in 2012 ? once in October, when he paid a $90 fine, and another instance in May when he paid $85.

Gazans struggle to reel in a livelihood

Mounir Abu Hasira?s name is synonymous with fish in Gaza, where his grandfather once owned more than 50 percent of the fishing boats and employed more than 2,000 workers to bring in the daily catch.

But since Israel reduced the permitted fishing zone from 20 miles to 12 miles to 3 miles ? progressive steps taken with the outbreak of the second intifada, the capture of Israeli soldier Gilad Shalit, and Hamas?s violent takeover of the tiny coastal territory in 2007 ? even Gaza?s scions of fishing can?t earn a living on the sea.

The number of working fishermen has dropped from 10,000 in 1999 to less than 3,200, according to a website advocating an end to the blockade.

Today 80 percent of the fish being sold at a seaside shack along the main drag in Gaza City comes from Israel or Egypt, says Mr. Abu Hasira, who now only fishes for fun. He still trades in fish though, holding up a big sea bass from the Red Sea that is more than twice the size of one caught here.

RECOMMENDED: Think you know the Middle East? Take our geography quiz.

With so many fishermen fighting for a livelihood in such a narrow corridor of water, the fish they are able to catch are much smaller. They are also caught younger, meaning they don?t have as much of a chance to breed before being harvested. Thus the population continues to dwindle.

As part of the November 2012 cease-fire with Hamas that ended eight-days of intense fighting, Israel agreed to double the fishing corridor to six miles. But after Gaza militants fired a volley of rockets into southern Israel in March, it was reduced to 3 miles again. Palestinian fishermen frequently complain of harassment by Israeli naval forces, especially as the fishermen approach the boundary of the zone.

The anti-blockade website lists 11 Palestinian fishermen who have been killed in the last five years. Detailed reports are given in about half the cases; all but one blame Israeli gunfire, though in one case Israeli forces were shooting at suspected militants in diving gear nearby.

?Now most fishermen are waiting for aid,? says Abu Hasira. ?One thing growing in fishermen is to be patient, so they are waiting.?

Abu Hasira made the decision not to wait, and left commercial fishing to open a fish restaurant, which is renowned as one of Gaza?s best. That enabled him to send his daughter to university.

?If I had been a fisherman, I couldn?t have afforded it,? he says.

Ancient water found in Canadian mine

Water drilled from rock in a North American mine is among the oldest yet found on Earth, say scientists.

Novel dating techniques used by the Canadian and UK team suggest the fluid is at least 1.5 billion years old.

The water was probably once on the surface and then percolated through the ground where it became trapped at a depth of 2.4km.

The discovery, made under Timmins, Ontario, is reported in this week's edition of the journal Nature.

Although far from any light source, particular types of micro-organism could survive in the water - it has the right chemistry; it is rich in dissolved gases like hydrogen and methane.

The team is currently testing its samples to determine whether any such lifeforms are indeed present.

"There are similar waters in South Africa with almost identical chemistry that are tens of millions of years old, and they contain microbes that have adapted to that environment," explained Prof Chris Ballentine from Manchester University.

"These are microbes that can survive on the energy from the natural water-rock interactions," he told BBC News.

A positive identification had fascinating implications for our understanding of how life evolved on the early Earth and where it could exist underground today on other planets, such as Mars, Prof Ballentine added.

Xenon marker

The water was recovered from deeply buried sulphide ores containing zinc and copper.

The researchers collected the water as mineworkers drilled new exploratory holes.

Temperature increases with depth and so the fluid emerged at 40-50C.

Three dating techniques were employed to work out how long the water trapped in the rock had been isolated.

A key method involved studying the different types, or isotopes, of xenon dissolved in the fluid.

The noble gas can be used as a marker to time when the fluid was last in contact with the atmosphere at the Earth's surface.

This approach only produces a broad age range, so the best the team can say is that the Timmins water had been resident underground for between 1.5 billion and 2.6 billion years. Even so, this is still hundreds of millions of years older than samples recovered from deep under South Africa's Witwatersrand Basin.

The only water known to be more ancient is found in minute quantities trapped in the voids in some rock minerals. These inclusions can be billions of years old.

Hidden reservoirs

Members of the research group at Toronto University are now examining the Timmins samples for their biological content.

Identifying microbes would go to the heart of issues about the habitability of deep Earth environments and for the prospects of finding life on other worlds.

Mars, for example, is cold and dry at its surface today, but the evidence suggests it was much warmer and wetter billions of years ago.

A lot of that early water was lost to space, but some of it is thought to have retreated to deep reservoirs.

Findings like those at Timmins raise the possibility that similar, long-isolated environments could yet persist on Mars, possibly supporting micro-organisms.

"The study has consequences for our understanding of how early life on Earth may have migrated into these kinds of environments and been protected from cataclysmic events at the surface," said Prof Ballentine.

"And being completely speculative, on somewhere like Mars, where the surface may have been habitable in its early history, water could have percolated into deep environments and been preserved on planetary timescales."

Blame campaign finance crusaders for IRS mess | The Daily Caller

In early 2010, the U.S. Supreme Court decided Citizens United, which prevents the federal government from suppressing speech by businesses and other groups. The decision freed up so-called ?super PACs,? which are widely regarded as having had a pernicious influence on the last several political cycles.

Since Citizens United, ?reformers? have demanded that the IRS ?crack down? on ?money in politics? by questioning the non-profit tax status of many political groups. The reformers got their wish.

The result: the huge and growing scandal in which the tax-collecting agency finds itself embroiled, with politicians on both sides of the aisle calling for investigations to be conducted and heads to roll.

In 2010, and more so in 2012, a quantity of political spending came through social welfare groups organized under Section 501(c)(4) of the tax code. These groups are not required to reveal their donors, but they are subject to the law in other ways. For example, the tax authorities say a (c)(4) group cannot have political engagement as its primary purpose. How much politics is too much, legally speaking, for such groups? Congress has not said, and the IRS has been reluctant to act on its own. Many election lawyers assume a group can spend almost half of its revenues on politics without risking its tax status.

Some people, known loosely as ?the reform community,? have little time for such legal nuances. They are outraged that (c)(4)?s refuse to disclose their donors. Since Citizens United, these putative reformers have been demanding that the IRS target (c)(4) groups and remove their tax status. This whole IRS mess, in other words, came about when a powerful pressure group was demanding the agency go after groups engaged in political speech. Many of the groups reiterated their demand for IRS action after the agency?s actions became public.

The phrase ?crack down? comes from reformist rhetoric. Consider the words. My dictionary defines ?crack down? as ?to suppress, prevent, put an end to, restrain, keep in control.? What is being suppressed and ended? Initially, only the use of a tax status. But there is more at stake. Much of the money raised by some (c)(4)?s goes toward political speech and related efforts like getting out the vote. In the first instance, the reformers are calling for a crack-down on First Amendment rights.

But the matter is more complicated. No one has a right to (c)(4) status. The IRS decides who gets the designation. In 2010, the agency?s decision-making was much delayed, thereby slowing down the grassroots engagement that marked the run-up to the midterm elections. Did the IRS intentionally delay this process? Many might recall that the tea party was critical of taxation and in some measure, the IRS. Even if the agency had no political motive, the process itself complicated political engagement, thus biasing the federal government toward the political status quo.

Sugar-sweetened beverages associated with increased kidney stone risk

May 15, 2013 ? Twenty percent of American males and 10 percent of American females will experience a kidney stone at some point in their lifetime. Often, these patients will be advised to drink more fluids as a way to prevent future stone formation. Now, new research from Brigham and Women's Hospital finds that some beverages may be more helpful than others when it comes to preventing recurrent kidney stones.

In a study published online May 15, 2013 in the Clinical Journal of the American Society of Nephrology (CJASN), researchers report that the consumption of sugar sweetened soda and punch is associated with a higher risk of stone formation.

"Our study found that the relation between fluid intake and kidney stones may be dependent on the type of beverage consumed," explained Gary Curhan, MD, ScD, a physician in the Channing Division of Network Medicine at BWH and senior author of this study. "We found that higher consumption of sugar-sweetened drinks was associated with a higher incidence of kidney stones."

The researchers analyzed data from three ongoing cohorts, the Health Professionals Follow-Up Study (HPFS), and both the Nurses' Health Study I (NHS I) and II (NHS II). The total analysis involved 194,095 participants over a median follow-up of more than 8 years. Participants in all the three cohorts had been asked to complete biennial questionnaires with information on medical history, lifestyle, and medication. Questions on diet were updated every four years. They found that participants who consumed one or more sugar-sweetened cola servings per day had a 23 percent higher risk of developing kidney stones compared with those participants consuming less than one serving per week. This was true for consuming sugar-sweetened non cola as well, such as punch. They also found that some beverages, such as coffee, tea and orange juice, were associated with a lower risk of stone formation.

"Our prospective study confirms that some beverages are associated with a lower risk of kidney stone formation, whereas others are associated with a higher risk," explained Pietro Manuel Ferraro, MD, a physician at the Catholic University of the Sacred Heart of Rome and corresponding author of this study. "Although higher total fluid intake reduces the risk of stone formation, this information about individual beverages may be useful for general practitioners seeking to implement strategies to reduce stone formation in their patients."

Google unveils maps, photo, music features

SAN FRANCISCO (AP) ? Google's sixth annual conference for software developers opened Wednesday with a chance for the company to showcase its latest services. Announcements included new features for online games, maps and search, a new music-streaming service and enhancements to its Google Plus social network, including tools for editing and sharing photos.

The audience of about 6,000 people at "Google I/O" included engineers and entrepreneurs who develop applications and other features that can make smartphones and tablets more appealing. Reporters from around the world were also on hand, giving Google a chance to generate more hoopla about its latest innovations. The keynote was also available live on a YouTube webcast.

Android already has been activated on 900 million devices made by Samsung Electronics Co., HTC Corp. and other manufacturers. Android devices are the chief rivals to Apple's iPhones and iPads. Android has helped Google make more money because its search engine and other services, including maps, are usually built into the devices. That tie-in drives more visitors to Google and gives the Mountain View, Calif., company more opportunities to sell ads.

The keynote kicked off at about 9 a.m. PDT and lasted about three and a half hours. The conference at the Moscone Center in San Francisco goes through Friday.

Here's a running account of the event, presented in reverse chronological order. All times are PDT. Presenters included CEO Larry Page; Vic Gundotra, Google's senior vice president for engineering; Sundar Pichai, Google's senior vice president for apps and Chrome; Hugo Barra, vice president for product management for Android; Ellie Powers, a product manager at Google; Brian McClendon, a vice president who oversees Google Maps; and Daniel Graf, director of Google Maps.

___

12:30 p.m.

Page complains about how laws haven't kept up with the pace of technology. He says trying to create a Google Health service for keeping track of medical records hasn't been easy because of regulations.

He also says it's necessary to start earlier to get girls and young women interested in technology. And he says smartphones need to become more affordable in poorer countries.

Page closes the keynote with a remark about being able to use his phone for just about everything he needs to run the company. He says it's remarkable to think of what can happen when more people can have such access.

As Page walks off the stage, Google announces that Billy Idol is the featured performer at Wednesday's after-hours party.

___

12:15 p.m.

Google offers no new details on its Google Glass, which is an Internet-connected device and camera that can be worn on a person's face like a pair of spectacles. At last year's conference, Google co-founder Sergey Brin teased its potential by conducting a live video chat with a group of skydivers who were in a dirigible hovering above the convention. When they jumped, the skydivers' descent to the rooftop was shown live through the Google Glass camera.

Google Glass is now being tested by developers who bought a prototype edition, and Page doesn't know when it will be available to the general public. Page says Google is relying on developers to come up with scenarios on using the product.

___

12:10 p.m.

Page takes the unusual step of inviting questions from the audience.

During the question-and-answer session, he talks about the importance of making rival systems work together rather than one company milking off another for its own benefit. Page takes aim at Microsoft and says, "We certainly struggle with people like Microsoft." Google says it recently made its chat service work with Microsoft's Outlook.com service but wasn't able to get Microsoft to reciprocate. Google didn't immediately elaborate.

Page also addresses Google's interest in developing super-fast Internet services in a few cities. He says it's sad that there's a lot of computing power out there, but "they are connected to each other through a tiny, tiny pipe that's super slow." He says that means most of those powerful computers "can't be used for anything useful."

___

Page complains about "the negativity of stories" in the news media. He says, "negativity isn't how we make progress. It's not zero-sum." He describes as "dumb" the stories that focus on rivalries, such as one between Google and Apple.

He also mentions his vision of driverless cars that will save people time and notes that "we are just scratching the surface of what is possible." Page says Google cooperated with Hollywood for the upcoming movie "The Internship" in order to address "a marketing problem" with technology.

Page appears on stage, a day after the CEO disclosed a problem with his vocal cords that makes it difficult for him to speak and breathe occasionally. Page has said he remains fit enough to keep running Google. Page doesn't always appear at Google conferences, and his appearance Wednesday could be meant to reassure people.

On stage, he talks about how his dad was interested in technology and once drove him across the country to attend a robotics conference. He says it's important to focus on technology and get more people involved.

He says, "Technology should do the hard work so people can get on doing the things that make them happiest in life."

His voice sounds raspy, but that is usual.

Google introduces new features for its mapping apps on Android devices and iPhones.

When you search for restaurants in a city or neighborhood, you'll get the names of the restaurants along with their ratings at the bottom of the screen. You can swipe through the results horizontally. The mapping app will also include Google Offers ? deals akin to those from Groupon Inc. and LivingSocial.

McClendon says Google has been trying to make its mapping services more useful by combining data from authoritative sources and using contributions from users. He says Google recently added more details on North Korea, with more listings of streets and parks rather than just a river and the city's name.

Graf takes a jab at Apple in talking about the success Google's mapping app has had on iPhones. Apple replaced Google's mapping service with its own app last fall. It resulted in complaints about inaccuracies and missing features. Google Maps returned on the iPhone with its own app a few months later. At Wednesday's conference, Graf points out that its app is "let's not forget, accurate."

Google is trying to integrate what it knows about users with its search function, so it can reply to questions like "What's my gate number?" or "my restaurant reservation."

Google already makes this available through its Google Now service on Android devices, iPhones and iPads. Now, it's available to anyone using its Chrome browser on traditional computers.

Google unveils several tools for sharing photos on its Google Plus social network.

One feature will pick out the best shots from a wide assortment of photos. Just upload a bunch, and Google's machines will reject ones that are blurry or don't have people smiling. Another factor is Google's knowledge of who's important to you ? so family members or close friends are more likely to make the cut.

If the photos don't look quite right, Google is promising to enhance them, taking over a job that typically requires people to use special photo-editing software such as Adobe System Inc.'s Photoshop, Apple's iPhoto or Google's Picasa. Computer-controlled editing tools will automatically soften skin tones and sharpen colors, for instance.

Google is also expanding the storage limit for full-resolution photos. Instead of five gigabytes for free per account, you'll get 15 gigabytes. Gundotra says that when you have an important photo, you don't want to sacrifice its quality to save space.

___

10:40 a.m.

Google is introducing 41 new features to its Google Plus social network, which Google is positioning as an alternative to Facebook.

Among them is a newly designed stream of content ? one designed to be dynamic, rather than a long list seen on Facebook.

Google Plus will start to display automatic hash tags to identify the main topic being discussed in a post or featured in a photo. You'll have the option to turn it off or remove it for a specific post. Google will also help you discover content by pulling up other posts with that hash tag. Facebook doesn't currently use hash tags.

Google is also streamlining its communications tools, offering a new app to combine its chat and Hangout services. Gundotra notes that Google's own services can be fragmented and confusing at time. The new app is designed to address that and can keep a record of past conversations. It will be available for Android and Apple devices, as well as regular Web browsers on computers.

The changes will start appearing Wednesday afternoon.

Everyone in the audience is getting a free Chromebook Pixel, a high-end laptop developed by Google. It has a high-resolution touch-screen display and usually carries a high price tag ? starting at $1,299. It runs Google's Chrome operating system, which is meant mostly for online use.

Google has said that selling Pixels isn't the company's main goal with the machine. Rather, the company made it to showcase Google's vision for the future of computing. So giving Pixels away to engineers and entrepreneurs is consistent with that strategy.

There's a new phone from Google. It will still run on the Android version called Jelly Bean, rather than Key Lime Pie ? the next in a series of dessert-themed code names.

It will be unlocked, meaning it will work with any carrier, including those abroad. But it also means the price won't be subsidized by the carrier. Google will sell it for $649 starting June 26, rather than the usual $200 or so with a two-year contract.

Google says the new phone is a variant of Samsung's Galaxy S4 phone, which was recently released. It's running a pure version of Android, the one that Google makes and distributes, rather than the one modified by Samsung to include a host of features that have been dismissed as confusing gimmicks in reviews by The Associated Press and others.

Google also says that the new phone will be able to get Android updates as they come. U.S. carriers sometimes block those updates from getting to locked phones.

9:50 a.m.

Google unveils a music service called All Access. The streaming service will allow Android users to listen to their favorite songs and artists for a monthly fee.

Google wants to not only offer access to millions of songs, but also help guide you to music you might like. You can choose one of 22 music genres and see key albums that define the genre along with recommendations from Google's curators. You can listen to any track right away, or switch to a "radio station" format featuring songs you'll likely want to hear. You can adjust the playlist as you go.

The cost is $9.99 a month in the U.S., after a 30-day free trial. It launches in the U.S. Wednesday. If you start the trial by June 30, the monthly fee will drop to $7.99. It will be available in other countries later.

Google's All Access will be competing with Spotify and other popular music services.

Powers introduces a service to help software developers get more users and make more money through their apps.

It will tell a developer, for instance, that an app is particularly popular in Russia, so that the developer could consider making a Russian-language version. Google is offering an app-translation service to help with that.

Another feature is designed to help developers understand how effective their ads are in getting people to download their apps.

___

Google introduces a technology for syncing notifications on different devices. The idea is when you dismiss a notification about a new Facebook message, for instance, it wouldn't reappear when you check your tablet.

Google also unveils new gaming tools. You can save where you are in a game and pick up on another device. You can also see how you rank on new leaderboards. This appears similar to what Apple offers on iPhones and iPads through its Game Center. Getting into gaming gives Google an opportunity to participate in one of the most popular activities on mobile devices.

___

9:20 a.m.

Barra introduces a few tools for software developers to incorporate into their apps. One allows apps to track what users are doing, such as walking. It may appear creepy to users, but Barra says the tools will allow developers to create "a whole new category of awesome apps."
