Hubble sees the remains of a star gone supernova

May 3, 2013 ? These delicate wisps of gas make up an object known as SNR B0519-69.0, or SNR 0519 for short. The thin, blood-red shells are actually the remnants from when an unstable progenitor star exploded violently as a supernova around 600 years ago. There are several types of supernovae, but for SNR 0519 the star that exploded is known to have been a white dwarf star -- a Sun-like star in the final stages of its life.

SNR 0519 is located over 150 000 light-years from Earth in the southern constellation of Dorado (The Dolphinfish), a constellation that also contains most of our neighboring galaxy the Large Magellanic Cloud (LMC). Because of this, this region of the sky is full of intriguing and beautiful deep sky objects.

The LMC orbits the Milky Way galaxy as a satellite and is the fourth largest in our group of galaxies, the Local Group. SNR 0519 is not alone in the LMC; the NASA/ESA Hubble Space Telescope also came across a similar bauble a few years ago in SNR B0509-67.5, a supernova of the same type as SNR 0519 with a strikingly similar appearance.

Nokia Lumia 928 billboard can't wait for official announcement to trumpet low-light camera performance

Nokia Lumia 928 billboard can't wait for official announcement, trumpets low-light camera

It's not uncommon for an as yet announced phone to pop up on Twitter, or via an insider leak. But a physical billboard? That takes some doing. If this image -- spotted out in the wild -- is to be believed, Nokia's Lumia 928 is as real as the day is long. The Verizon handset shown certainly fits the images we've already seen, and the low-light boast will stoke the coals of any Xenon or PureView rumors for sure. However, this spot is hardly Times Square, so until we see something a little more concrete, Lumia fans on Big Red will have to keep the faith with that 822.

Wide-eyed fear expressions may help us ? and others ? to locate threats

May 1, 2013 ? Wide-eyed expressions that typically signal fear seem to enlarge our visual field making it easier to spot threats at the same time they enhance the ability of others to locate the source of danger, according to new research from the University of Toronto.

The research by Daniel Lee, a graduate student in the Department of Psychology is published on the Association for Psychological Science's Psychological Science journal website.

"Emotional expressions look the way they do for a reason," says Lee. "They are socially useful for communicating emotional states, but they are also useful as raw physical signals. In the case of widened eyes, they help send a clearer gaze signal that tells observers to 'look there.'"

Lee, his supervisor Adam Anderson also of U of T's psychology department and Joshua Susskind of University of California, San Diego first found that participants who made wide-eyed fear expressions could literally see more: they were able to discriminate visual patterns farther out in their peripheral vision than participants who made neutral expressions or expressions of disgust.

Next, they investigated the benefits that wide-eyed expressions might confer to onlookers. They found that participants were better able to tell which direction a pair of eyes was looking as the eyes became wider. And these wider eyes helped participants respond to targets that were located in the direction of the gaze. Importantly, these benefits did not depend on recognizing the eyes as fearful.

Wide-eyed expressions are helpful for onlookers quite simply because as eyes become wider, we can see more of the iris and whites of the eyes, known as sclera. This directly increases the physical contrast and information signal, making it easier to tell where someone is looking.

"Our eyes are important social signals," says Lee. "This research really shows how social we are wired to be."

Obama nominates Congressman for housing post

WASHINGTON (AP) ? President Barack Obama acted Wednesday to fill two top regulatory posts, tapping a veteran Democratic congressman to lead the Federal Housing Finance Agency at a pivotal time for the housing market and naming a top campaign fundraiser and former lobbyist to head the Federal Communications Commission.

Rep. Melvin Watt, D-N.C., would oversee the government-controlled mortgage lenders Fannie Mae and Freddie Mac just as the industry is beginning a comeback. He would succeed Edward DeMarco, an appointee of Republican President George W. Bush. DeMarco's refusal to allow Fannie and Freddie to reduce principal costs for homeowners at risk of foreclosure made him a target of housing advocates, liberal groups and Democratic lawmakers.

Watt, 67, has spent 20 years in the House, all of it on the Financial Services Committee, which oversees federal housing policy. Introducing Watt at the White House, Obama said the Charlotte-area congressman had led efforts to rein in unscrupulous mortgage lenders, protect consumers from the kind of risk-taking that led to the 2008 financial crisis and has championed increased access to affordable housing.

"Mel understands as well as anybody what caused the housing crisis," Obama said. "He knows what it's going to take to help responsible homeowners fully recover."

Watt's selection was praised by housing advocates, liberal groups and lawmakers in both political parties.

Tom Wheeler, former head of the Cellular Telecommunications and Internet Association, and the National Cable Television Association, would become the nation's top telecommunications regulator. He has been a venture capitalist since 2005 and he raised more than a half million dollars for Obama's re-election, according to data provided by the campaign.

Wheeler would replace Julius Genachowski, who announced his resignation in March. Obama spoke effusively on Wednesday about Genachowski, his pal from their days together at Harvard Law School.

Obama also sought to allay any concerns that Wheeler would be unable to effectively regulate an industry he once represented, saying Wheeler has spent more than 30 years at the forefront of dramatic change in a "communications universe that is growing and changing faster than you can tweet."

"He's like the Jim Brown of telecom, or the Bo Jackson of telecom," Obama joked, comparing the slender, bespectacled 67-year-old to the two former professional athletes. "So Tom knows this stuff inside and out."

Senate confirmation is required for both posts.

Obama said he would nominate FCC Commissioner Mignon Clyburn, a daughter of Assistant House Democratic Leader Jim Clyburn of South Carolina to lead the agency until Wheeler is confirmed.

Watt's nomination comes at a crucial time for Fannie Mae and Freddie Mac, which were rescued by the government at the height of the financial crisis in September 2008 as they neared collapse from losses on bad mortgage loans. Taxpayers spent about $170 billion on the rescue but so far have received about $55.2 billion in repayment.

Fannie and Freddie together own or guarantee about half of all U.S. mortgages, nearly 31 million home loans worth more than $5 trillion. Along with other federal agencies, they back roughly 90 percent of new mortgages.

Recent economic data shows the housing industry beginning a comeback since plunging into a depression during the financial crisis. Home prices are up, foreclosures are down and housing construction is rising. Moreover, Fannie Mae had its biggest yearly profit last year, earning $17.2 billion.

Meanwhile, a Congressional Budget Office report released Wednesday found that principal reduction for struggling borrowers by Fannie and Freddie would result in savings to taxpayers of up to $2.8 billion. It also would reduce mortgage defaults by between 18,000 and 95,000 and give a slight boost to economic growth, the report said.

Watt, a senior member of the House Financial Services Committee and former Congressional Black Caucus chairman, played an influential role in the passage of a financial regulatory overhaul in 2010. That legislation, however, did not address the fate of the major mortgage lenders, an issue likely to be revisited during Obama's second term.

In fact, two Republicans ? Sen. Bob Corker of Tennessee and Rep. Jeb Hensarling of Texas ? called on the administration to present a plan to overhaul the country's housing finance system.

"This gives new meaning to the adage that the fox is guarding the henhouse," said Corker, who sits on the Senate Banking, Housing and Urban Affairs Committee, in a written statement. "The debate around his nomination will illuminate for all Americans why Fannie and Freddie failed so miserably."

Corker said the administration should "explicitly lay out" its plans for dissolving Fannie and Freddie before the committee considers anyone for the FHFA's top job.

The administration presented such a plan in 2011, with the goal of shrinking the government's role in the mortgage finance system, but Congress has yet to decide on how to limit federal involvement.

Republican Sen. Richard Burr of North Carolina endorsed Watt, saying he looks forward to working with his former House colleague to encourage more involvement by the private sector in the housing and mortgage markets.

"Having served with Mel, I know of his commitment to sustainable federal housing programs and am confident he will work hard to protect taxpayers from future exposure to Fannie Mae and Freddie Mac," Burr said in a statement.

Treasury Secretary Jacob Lew said the administration still wants to work with Congress on overhauling the mortgage finance system.

Watt is the latest African-American and the second North Carolinian nominated to top government jobs this week. On Monday, Obama tapped Charlotte Mayor Anthony Foxx to become transportation secretary.
