Polar Bear And Its Cub Drift On Shrinking Ice 12 Miles From Land ... But Is It All It Seems?
From The Daily Mail:
A forlorn polar bear cub is comforted by its mother as they drift miles from shore on a rapidly shrinking ice floe.
The Arctic-dwelling animals have become an iconic cause for green campaigners, who claim dramatic images such as these prove that global warming is destroying the world.
But despite this image being released today, it was actually taken in August last year, when it is normal for coastal ice to naturally break up and melt.

Secrets Of The Ancients
From Cosmos:
King Tut is only one in a growing list of ancient humans forced to reveal their secrets through high-tech prodding. By rushing into such studies, we may be opening a historical Pandora's Box.
On 26 November 1922, the British Egyptology Howard Carter peered through a tiny hole into the tomb of Tutankhamun in the Valley of the Kings.
"I see wonderful things," he gasped as he glimpsed a profusion of gold and ebony, hidden for more than 30 centuries.

Why Chile’s Massive Earthquake Could Have Been Much Worse
From Discover Magazine:Less than two months after the earthquake that shook Haiti, and only hours after a quake causing small tsunamis occurred near Japan, the largest of 2010’s seeming barrage of big seismic events hit Chile. The 8.8 earthquake is the fifth largest since 1900. “We call them great earthquakes. Everybody else calls them horrible,” said USGS geophysicist Ken Hudnut. “There’s only a few in this league” [AP].
According to seismologists, the confluence of earthquakes these last couple months are probably coincidental; they’re all separated by too great a distance to be directly related. However, some say the latest quake is related to the 1960 quake in Chile that remains the largest ever recorded, a 9.5 on the Richter scale.

Mars Rover Spirit Could Rise Again
From New Scientist:
NASA's Spirit rover should be able to wriggle free of its sandy trap on Mars after all, says a scientist for the mission. But the plucky robotic explorer will need to survive the bitter Martian winter first.
In April 2009, Spirit's wheels broke through a thin surface crust and got mired in the loose sand below. After months of trying unsuccessfully to free the rover, NASA declared on 26 January that Spirit would henceforth be a stationary lander mission rather than a rover.

Massive Solar Storms of the Future Could Reap Katrina-Scale Devastation
From Popular Science:
If storms as strong as the biggest recorded in the last few two centuries, our electronics-dependent world of today could be in trouble.
No electricity, no running water, and no phone service for millions of people. That scenario could easily become reality if a solar storm as intense as those found throughout the history of our planet were to strike Earth today. NPR reported on FEMA's recent simulation of such a storm, and the grim conditions it uncovered.

Facebook Users Keep It Real In Online Profiles
From New Science:Young adults apparently present their true selves on the world's biggest social network.
“On the Internet,” one dog tells another in a classic New Yorker cartoon, “nobody knows you’re a dog.”
The Internet is notorious for its digital dens of deception. But on Facebook, what you see tends to be what you get — at least in one study of tailless, two-legged young adults.

Is The iPad Launch Really Delayed?
(Credit: Apple)From The CNET:
When Apple introduced the iPad in January, it said the device would be made available in late March. However, one analyst is now saying the launch may be delayed.
Peter Misek, an analyst with Canaccord Adams, wrote in a note to clients on Monday that production problems could limit Apple's launch of the iPad. The production issues could be bad enough to even delay the launch for a month, according to a report on AppleInsider.

Science Daily (Mar. 2, 2010) — The Feb. 27 magnitude 8.8 earthquake in Chile may have shortened the length of each Earth day.
JPL research scientist Richard Gross computed how Earth's rotation should have changed as a result of the Feb. 27 quake. Using a complex model, he and fellow scientists came up with a preliminary calculation that the quake should have shortened the length of an Earth day by about 1.26 microseconds (a microsecond is one millionth of a second).

Titanic vs. Lusitania: Time Determined Who Survived
From Live Science:
The time people have during survival situations might affect whether they behave selfishly or socially. Examining two shipwrecks, the Titanic and the Lusitania, researchers recently found the longer passengers had to react to the disaster, the more likely they were to follow social mores. The less time, the more selfishly passengers behaved.
The result: It was every man for himself aboard the rapidly sinking Lusitania, and so the fittest were the most likely to survive that accident. During the lengthy Titanic shipwreck, women in their reproductive years were the most likely to make it, while men of the same age had a lower probability of surviving.

What's Wrong With Venture Capital?
The exception: Google’s successful initial public offering over five years ago did not usher in a new era of good times for venture capitalists; it merely served to underscore how rare these happy events have become. Credit: Getty ImagesFrom Technology Review:
The old mechanism for funding the commercialization of new technologies is in trouble.
In the summer of 1996, Silicon Valley venture capitalists put a few million dollars into a telecom-equipment startup called Juniper Networks. Three years later, after a few more rounds of funding and the release of its first product, Juniper enjoyed an initial public offering of shares, or IPO. At the end of its first day of trading, it was worth nearly $5 billion, and within nine months, it was worth almost 10 times that. The original venture investors, meanwhile, were able to walk away with profits of better than 10,000 percent.

Coldest Winter In UK For More Than 30 Years... But Met Office Defends Its Long Range Forecast
Mothers tow children on their sledges in Hampshire, in January. The Met Office has confirmed that 2009/10 winter was the coldest since 1978/79From The Daily Mail:
Perhaps someone should ask workers at the Met Office to take a rain check on their optimism.
After predicting just a 20 per cent chance of a colder than average winter, they were left embarrassed again when official figures revealed it was the coldest for more than 30 years.
Temperatures in December, January and February struggled to stay above zero, with the UK's average a chilly 1.5c (35f), making it the deepest freeze since 1978-79.

The Mystery Of The Silent Aliens
From New Scientist:Sixty years ago, space aliens were the preserve of lunatics and eccentrics, thanks to decades of sci-fi schlock, flying-saucer nonsense and Lowellian fantasies of Martian canals. Then, in 1950, came Enrico Fermi and his paradox - "Where the hell is everyone?" - and, 10 years later, the first attempts to put the search for ET on a scientific footing, courtesy of Frank Drake, who pointed a radio telescope at Tau Ceti and heard... silence.

Etched Ostrich Eggs Illustrate Human Sophistication

From The BBC:
Inscribed ostrich shell fragments found in South Africa are among the earliest examples of the use of symbolism by modern humans, scientists say.
The etched shells from Diepkloof Rock Shelter in Western Cape have been dated to about 60,000 years ago.
Details are reported in the Proceedings of the National Academy of Sciences.
The researchers, who have investigated the material since 1999, argue that the markings are almost certainly a form of messaging - of graphic communication.

'Ministrokes' May Cause More Damage Than Thought
From New Science:Common test given to patients after the passing attacks appears to miss some cognitive impairments.
SAN ANTONIO — As many as four in 10 people referred to a clinic with signs of a “ministroke” may have subtle cognitive damage that standard tests miss, a new study shows.
The findings, reported by Canadian researchers February 24 at the International Stroke Conference in San Antonio, Texas, suggest that after suffering the ministrokes many patients lose some ability to process abstract thoughts, reason things out and make quick calculations — what doctors call “executive function.”

Titanic vs. Lusitania: How People Behave In A Disaster
From Time Magazine:
It's hard to remember your manners when you think you're about to die. The human species may have developed an elaborate social and behavioral code, but we drop it fast when we're scared enough — as any stampeding mob reveals.
That primal push-pull is at work during wars, natural disasters and any other time our hides are on the line. It was perhaps never more poignantly played out than during the two greatest maritime disasters in history: the sinking of the Titanic and the Lusitania. A team of behavioral economists from Switzerland and Australia have published a new paper in the Proceedings of the National Academy of Sciences (PNAS) that takes an imaginative new look at who survived and who perished aboard the two ships, and what the demographics of death say about how well social norms hold up in a crisis.

Microsoft's Ballmer Talks Bing, Twitter
From CNET:
SANTA CLARA, Calif.--Microsoft CEO Steve Ballmer maintains a secret Twitter account for providing running commentary on high-school basketball matches: but that doesn't mean he wants to buy the company.
Ballmer's booming voice filled the Santa Clara Convention Center on Tuesday morning at SMX West, where he was interviewed on stage by Search Engine Land's Danny Sullivan on a wide range of topics related to Microsoft, Bing, and the company's struggling yet strategically important Internet business. Having wrapped up its search deal with Yahoo and restructured a separate search and advertising deal with Facebook, it wouldn't be surprising if Ballmer was looking for something new to do with that division.
