Online real estate listing aggregator Zillow launched an app today that aims to help home shoppers and home buyers with their home improvement projects.


Available for the
iPad and the Web, Zillow Digs is a free app designed to offer inspiration as well as information about remodeling projects. The free app lets users browse thousands of photos of bathroom, kitchen, and outdoor projects, as well as get estimates on the cost of the actual project based on the user's location.


The app also allows users to create, save, and share Pinterest-like boards containing their ideas and interact with other users who may have similar ideas. The app also offers connections to local industry professionals, such as architects, contractors, and designers.




"Tens of millions of home buyers shop for homes on Zillow each month, and home improvement is a natural next step for us in consumer empowerment and transparency of information to help people make smarter decisions," Zillow CEO Spencer Rascoff said in a statement. This first-of-its-kind remodeling cost estimate algorithm was created by Zillow's industry-leading team of economists and data analysts who produce extensive housing data and research."


Founded in 2004 and launched as a Web site in 2006, Zillow has a sales and rental database on more than 110 million U.S. homes. The company's revenue comes from real estate professionals' subscription fees and advertising.


In 2008, the company launched Mortgage Marketplace, which lets prospective borrowers get quotes anonymously and lenders get leads for free.

The Real Richard III


It's a question that actors from Laurence Olivier to Kevin Spacey have grappled with: What did Richard III, the villainous protagonist of Shakespeare's famous historical drama, really look and sound like?

In the wake of this week's announcement by the University of Leicester that archaeologists have discovered the 15th-century British king's lost skeleton beneath a parking lot, news continues to unfold that helps flesh out the real Richard III.

The Richard III Society unveiled a 3D reconstruction today of the late king's head and shoulders, based on computer analysis of his skull combined with an artist's interpretation of details from historical portraits. (Related: "Shakespeare's Coined Words Now Common Currency.")

"We received the skull data before DNA analysis confirmed that the remains were Richard III, and we treated it like a forensic case," said Caroline Wilkinson, the University of Dundee facial anthropologist who led the reconstruction project. "We were very pleasantly surprised by the results."

Though Shakespeare describes the king as an "elvish-marked, abortive, rooting hog," the reconstructed Richard has a pleasant, almost feminine face, with youthful skin and thoughtful eyes. His right shoulder is slightly higher than the left, a consequence of scoliosis, but the difference is barely visible, said Wilkinson.

"I think the whole Shakespearean view of him as being sort of monster-like was based more on his personality than his physical features," she reflected.

Look back at 125 years of National Geographic history

People are naturally fascinated by faces, especially of historical figures, said Wilkinson, who has also worked on reconstructions of J.S. Bach, the real Saint Nicholas, the poet Robert Burns, and Cleopatra's sister.

"We make judgments about people all the time from looking at their appearance," she said. "In Richard's case, up to now his image has been quite negative. This offers a new context for considering him from the point of view of his anatomical structure rather than his actions. He had quite an interesting face."

A Voice From the Past

Most people's impression of Richard's personality comes from Shakespeare's play, in which the maligned ruler utters such memorable lines as "Now is the winter of our discontent/Made glorious summer by this son of York," and "A horse! A horse! My kingdom for a horse!"

But how would the real Richard III have expressed himself? Did he have an accent? Was there any sense of personality or passion in his choice of words?

To find out more about the mysterious monarch, Philip Shaw, a historical linguist at University of Leicester's School of English, analyzed the only two known examples of Richard III's own writing. Both are postscripts on letters otherwise composed by secretaries—one in 1469, before Richard became king, and one from 1483, the first year of his brief reign.

Shaw identified a quirk of spelling that suggests that Richard may have spent time in the West Midlands, or perhaps had a tutor who hailed from there.

"I was looking to compare the way he spells things with the way his secretaries spell things, working on the assumption that he would have been schooled to a fairly high level," Shaw explained.

In the 1469 letter, Richard spells the word "will" as "wule," a variation associated with the West Midlands. But Shaw also notes that by 1483, when Richard wrote the second letter's postscript, he had changed his spelling to the more standard "wyll" (the letters 'i' and 'y' were largely interchangeable during that period of Middle English).

"That could suggest something about him brushing up over the years, or moving toward what would have been the educated standard," Shaw said, noting that the handwriting in the second example also appears a bit more polished. "One wonders what sort of practice and teaching he'd had in the interim."

Although it's hard to infer tone of voice from written letters, there is certainly emotion in the words penned by Richard III.

In the 1469 letter, the 17-year-old seeks a loan of 100 pounds from the king's undertreasurer. Although the request is clearly stated in the body of the letter, Richard adds an urgent P.S.: "I pray you that you fail me not now at this time in my great need, as you will that I show you my good lordship in that matter that you labour to me for."

That could either be a veiled threat (If you don't lend me the money, I won't do that thing you asked me to do) or friendly cajoling (Come on, I'm helping you out with something, so help me out with this loan).

"His decision to take the pen himself shows you how important that personal touch must have been in getting people to do something," Shaw said.

The second letter, written to King Richard's chancellor in 1483, also conveys a sense of urgency. He had just learned that the Duke of Buckingham—once a close ally—was leading a rebellion against him.

"He's asking for his Great Seal to be sent to him so that he can use it to give out orders to suppress the rebellion," Shaw said. "He calls the Duke 'the most untrue creature living. You get a sense of how personally let down and betrayed he feels."

Shaw said he hopes his analysis—in combination with the new facial reconstruction—will help humanize Richard III.

"He probably wasn't quite the villain that Shakespeare portrays, though I suspect he was quite ruthless," he said. "But you probably couldn't afford to be a very nice man if you wanted to survive as a king in those days."

White House: Drone Strikes on Americans 'Legal'





Feb 5, 2013 3:54pm


The White House today defended the use of targeted drone strikes against U.S. citizens abroad suspected of high-level terrorist activity, but declined to detail the criteria for ordering such an attack.


“Sometimes we use remotely piloted aircraft to conduct targeted strikes against specific al Qaeda terrorists in order to prevent attacks on the United States and to save American lives,” White House Press Secretary Jay Carney told reporters.


“We conduct those strikes because they are necessary to mitigate ongoing actual threats, to stop plots, to prevent future attacks and, again, save American lives. These strikes are legal, they are ethical, and they are wise,” he said.

U.S. Air Force


Administration lawyers found it is lawful to kill an American citizen if a “high-level” government official believes the target is an operational leader of al Qaeda who poses “an imminent threat of violent attack against the United States” and if capture is infeasible, according to a newly disclosed Justice Department document.


The 16-page white paper, first obtained by NBC News, finds there “exists no appropriate judicial forum to evaluate these constitutional considerations” and that the administration does not need to present evidence to a court before or after ordering such an attack.


“The condition that an operational leader present an ‘imminent’ threat of violent attack against the United States does not require the United States to have clear evidence that a specific attack on U.S. persons and interests will take place in the immediate future,” the document reads.


Carney repeatedly declined to discuss the details of the white paper.


“I would point you to the ample judicial precedent for the idea that someone who takes up arms against the United States in a war against the United States is an enemy and therefore could be targeted accordingly,” he told ABC News’ Jon Karl.


“[The president] takes his responsibility as commander in chief to protect the United States and its citizens very seriously. He takes the absolute necessity to conduct our war against al Qaeda and its affiliates in a way that’s consistent with the Constitution and our laws very seriously,” he said.


The white paper is believed to be a summary of the reported classified memo that outlined the legal justification for the drone attack that killed American-born radical cleric Anwar al-Awlaki in September 2011.


The American Civil Liberties Union has called the newly discovered document “profoundly disturbing.”


“It’s hard to believe that it was produced in a democracy built on a system of checks and balances. It summarizes in cold legal terms a stunning overreach of executive authority — the claimed power to declare Americans a threat and kill them far from a recognized battlefield and without any judicial involvement before or after the fact,” ACLU National Security Project director Hina Shamsi said in a written statement.


The Obama administration has carried out more than 300 CIA drown strikes in Pakistan, far more than his predecessor, President George W. Bush, according to the Bureau of Investigative Journalism.


Pressure is building from Capitol Hill for the White House to outline its legal authority to kill American citizens in counterterrorism operations.


“It is vitally important… for Congress and the American public to have a full understanding of how the executive branch interprets the limits and boundaries of this authority,” a group of eleven bipartisan Senators wrote in a letter to the president Monday, “so that Congress and the public can decide whether this authority has been properly defined, and whether the President’s power to deliberately kill American citizens is subject to appropriate limitations and safeguards.”

Ice-age art hints at birth of modern mind



Sumit Paul-Choudhury, editor

Figurines from the Don river valley (Images: Kirstin Jennings)


The world’s oldest portrait, the world’s first fully carved sculpture, the world's oldest ceramic figure, the world’s earliest puppet - there’s no shortage of superlatives in the new exhibition of art from the ice age at the British Museum in London


But focus too closely on the exhibits’ record-breaking ages alone, and you might miss the broader point: these beautiful objects are the earliest evidence we have of humans who seem to have had minds like ours.






lionman.jpg

Consider, for example, the "lion man" found in 1939 in south-west Germany’s Stadel cave (pictured above). As the name suggests, this statue, standing 30 centimetres tall, harmoniously combines human and leonine features: the head is unmistakeably a lion’s, while the body and lower limbs are more human.


This is clearly the product of artistic creativity rather than a naturalistic drawing from life - suggesting that whoever carved it some 40,000 years ago had the capacity to express their imagination, as well as to replicate what they saw around them.


The temptation to speculate about what symbolic meaning the lion man might have had is, of course, irresistible. It was clearly valuable, taking around 400 hours and enormous skill to carve from a single piece of mammoth ivory.


The exhibition also includes a second, much smaller, feline figure found in another cave nearby, pointing to the idea that such imaginative objects might have cultural significance, perhaps as ritual objects within a shamanic belief system, rather than being isolated art objects.


Given what we know of modern traditions, that would make sense - but there is no hard evidence that anything resembling those traditions existed in Europe during the ice age.


Almost every object on show invites similarly thought-provoking consideration. Thumb-sized figurines from settlements along Russia's Don river (top) seem to present a woman's perception of her own pregnant body in an age before mirrors: no face, bowed head, the shelf of the bosom, the protrusion of the hips and buttock muscles and the swell of the belly. Were they carved by the women themselves, perhaps as protective talismans for themselves or their unborn children? And if so, what are we to make of those that were apparently deliberately destroyed subsequently?


Only a few of the animal models found at the Czech site of Dolní Věstonice are intact. The rest had shattered into thousands of clay fragments when they were heated while still wet. This must also have been deliberate: was the dramatic shattering part of a rite?


A tiny relief of a human figure with upraised arms invites interpretation as a celebrant or worshipper. Was he or she participating in a ceremony to promote social cohesion during tough times - perhaps to the accompaniment of music played on instruments such as the flute displayed nearby, which is precisely carved from a vulture's wing-bone?


Such interpretations deserve a healthy dose of caution, of course. The note accompanying an elegantly carved water bird (perhaps a cormorant) found near the smaller lion man drily reads: "This sculpture may be a spiritual symbol connecting the upper, middle and lower worlds of the cosmos reached by a bird that flies in the sky, moves on land and dives through water. Alternatively, it may be an image of a small meal and a bag of feathers."


In the total absence of documentary evidence, there is no way of telling which is correct: archaeological material might help clarify the utilitarian perspective, but it is far less helpful when it comes to discovering any symbolic value.


In any case, there is very little archaeological evidence on display at the British Museum. Curator Jill Cook says she was keen to avoid exhausting visitors with copious background material about the evolutionary and environmental contexts in which these objects were made.


Humans were capable of complex behaviour long before they reached Europe - as demonstrated by discoveries such as the 100,000-year old "artist's workshop" in South Africa's Blombos cave - but Cook thinks the explosion of art among Europeans 40,000 years ago may reflect changing social needs during the ice age.


When Homo sapiens first arrived in Europe some 45,000 years ago, "the living was initially probably reasonably easy", explains Cook. They would have found temperatures only about 5 °C lower than they are now, she says, and grassy prairies would have been well stocked with bison. As the human population grew, they would have had to find new ways of building, socialising and organising themselves.


“And as it turns desperately cold, around 40,000 years ago, suddenly we have all this art," she says.


That may have reflected the need to communicate and develop ideas - a need pressing enough for people to spend hundreds of hours creating objects that generally seem to have had little quotidian function.


"This is all about planning and preconceiving and organising and collaborating and compromising," suggests Cook, "and that is something art and music helps us do."


The dazzling array of objects on display, spanning tens of thousands of years, anticipate practically every modern artistic tradition. The first portrait, dating back 26,000 years, includes closely modelled details of its female subject's unusual physiognomy, perhaps the result of an injury or illness.


But nearby is an extraordinary figure of similar age whose facial features are utterly abstract, resembling a visor with a double slit in it.


picasso-inspiration.jpg

Another (above) has a body whose angular patterns anticipate Cubism by some 23,000 years: Picasso kept two copies of it in his studio. Elsewhere, there are doll-like models of women with stylised faces, and female forms streamlined into little more than slender, strategically curved lines.


movement.jpg

Representations of animals, too, come in all forms, from incredibly realistic illustrations scratched onto stone or ivory, to elegantly minimal sculptures; there are even carvings designed to create the illusion of movement when viewed from different angles or rotated (above) - a form of prehistoric animation.


The masterpieces in the latter part of the show include - and sometimes combine - both precisely observed, superbly rendered naturalism, and more abstract work that is still beautiful, but much harder to interpret.


tusks.jpg

Carved mammoth tusks


"The brain likes to tease us," says Cook. "We don't just represent things with great realism and naturalism, we like to break things down into patterns. That sparks your imagination, and makes you curious and questioning.


“What’s so spectacular about the modern brain, and the mind that it powers, is that it doesn't just make everything simple, it pushes us to new ideas and new thoughts."


After tens of thousands of years, the objects displayed in this extraordinary exhibition still have the power to do just that.

"Wild Thing" singer Reg Presley dies at 71






LONDON: Reg Presley, lead singer of British 1960s rock band The Troggs, has died aged 71, a friend said late Monday.

Presley, best known for hits including "Wild Thing" and "Love Is All Around", had announced a year ago that he was battling cancer and would retire from the band.

Veteran music journalist Keith Altham, a close friend of Presley's, wrote on his Facebook page that the singer had died "surrounded by family and friends" on Monday at his home in Andover, southeast England.

"My dear old pal Reg Presley of The Troggs died today," he wrote.

"He was one very real person in a sometimes very unreal world. Our thoughts are with his wife Brenda and the the family and those legion of fans who loved his music and his band. I will miss him hugely."

He added that the singer had suffered a number of recent strokes as well as being diagnosed with cancer.

Presley's daughter Karen told the music website WENN: "He passed away peacefully at home and myself, my brother and our mother were with him. We're absolutely heartbroken."

The singer had announced his retirement in January 2012 after he was taken ill during a gig in Germany the previous month.

"During my stay in hospital tests showed that in fact I have lung cancer," he wrote in a letter posted on the band's website.

"I am receiving chemotherapy treatment and at the moment not feeling too bad.

"However I've had to call time on The Troggs and retire. I would like to take this opportunity to thank you all for the cards and calls and for your love, loyalty and support over the years."

The Troggs' manager did not immediately respond when contacted by AFP.

Hackers hit U.S. Department of Energy



The U.S. Department of Energy said that hackers have stolen personal data of its employees and contractors.



The U.S. Department of Energy has confirmed that its computer systems were hacked into last month. According to The New York Times, the federal agency sent around an internal e-mail on Friday telling its employees about the cyberattack.

"The Department of Energy has just confirmed a recent cyber incident that occurred in mid-January which targeted the Headquarters' network and resulted in the unauthorized disclosure of employee and contractor Personally Identifiable Information," the e-mail said.

The agency said that it is working to figure out the "nature and scope of the incident" but that so far it believes "no classified data was compromised." It's unclear which divisions within the Department of Energy were attacked or who was behind the hack.

The Department of Energy is in charge of much of the country's vital infrastructure, such as energy production, nuclear reactor production, and radioactive waste disposal. It has troves of classified and sensitive data that if leaked could be detrimental to the country's security. According to Reuters, the most highly classified information is stored on networks that aren't connected to the Internet.

The head of Homeland Security Janet Napolitano recently announced that she believes a wave of cyberattacks on U.S. infrastructure is a serious possibility. Dubbing such an event a "cyber 9/11," Napolitano warned that cyberterrorists could take down the nation's power grid, water infrastructure, transportation networks, and financial networks.

While it doesn't seem like the January cyberattack on the Department of Energy compromised any data or infrastructure, it does show that hackers were able to breach the government's computer systems. In the e-mail, the agency said it is working to fortify itself against future attacks.

"Once the full nature and extent of this incident is known, the Department will implement a full remediation plan," the e-mail said. "The Department is also leading an aggressive effort to reduce the likelihood of these events occurring again. These efforts include leveraging the combined expertise and capabilities of the Department's Joint Cybersecurity Coordination Center to address this incident, increasing monitoring across all of the Department's networks and deploying specialized defense tools to protect sensitive assets."

CNET contacted the Department of Energy for comment. We'll update the story when we get more information.

Space Pictures This Week: A Space Monkey, Printing a Moon Base

Illustration courtesy Foster and Partners/ESA

The European Space Agency (ESA) announced January 31 that it is looking into building a moon base (pictured in an artist's conception) using a technique called 3-D printing.

It probably won't be as easy as whipping out a printer, hooking it to a computer, and pressing "print," but using lunar soils as the basis for actual building blocks could be a possibility.

"Terrestrial 3-D printing technology has produced entire structures," said Laurent Pambaguian, head of the project for ESA, in a statement.

On Earth, 3-D printing, also known as additive manufacturing, produces a three-dimensional object from a digital file. The computer takes cross-sectional slices of the structure to be printed and sends it to the 3-D printer. The printer bonds liquid or powder materials in the shape of each slice, gradually building up the structure. (Watch how future astronauts could print tools in space.)

The ESA and its industrial partners have already manufactured a 1.7 ton (1.5 tonne) honeycombed building block to demonstrate what future construction materials would look like.

Boy Safe, Kidnapper Dead After Hidden Camera Tip













A week-long standoff in Alabama, where a retired trucker held a 5-year-old boy hostage in an underground bunker, has ended with the kidnapper dead and the child safe, according to law enforcement.


Officials had been able to insert a high-tech camera into the bunker to monitor the movements of the suspect, Richard Lee Dykes, and they had become increasingly concerned that he might act out, according to a law enforcement source with direct knowledge.


"FBI agents safely recovered the child who's been held hostage for nearly a week," FBI Special Agent Steve Richardson said at a news conference.


The agent said negotiations with Dykes "deteriorated" in the past 24 hours.


"Mr. Dykes was observed holding a gun," Richardson said. "At this point, the FBI agents, fearing the child was in imminent danger, entered the bunker and rescued the child."


The boy, identified only as Ethan, "appears physically unharmed" and is being treated at a hospital, authorities said.

Dykes, 65, is dead, but officials have not yet provided details on how he died.


"Right now, FBI special agent bomb technicians are in the process of clearing the property for improvised explosive devices," the FBI said in a written statement. "When it is safe to do so, our evidence response teams, paired with state and local crime scene technicians, will process the scene."

Dykes allegedly shot and killed a school bus driver last week and threatened to kill all the children on the bus before taking the boy, one of the students on the bus said.


"He said he was going to kill us, going to kill us all," Tarrica Singletary, 14, told ABC News.


Dykes had been holed up in his underground bunker near Midland City, Ala., with the abducted boy for a week as police tried to negotiate with him through a PVC pipe. Police had used the talks to send the child comfort items, including a red Hot Wheels car, coloring books, cheese crackers, potato chips and medicine.


Dykes was a decorated Vietnam vet who grew up in the area. He lived in Florida until two years ago, the AP reported, and has an adult daughter, but the two lost touch years ago, neighbor Michael Creel said. When he returned to Alabama, neighbors say he once beat a dog with a lead pipe and had threatened to shoot children who set foot on his property.
