Space Station Needs 'Extension To 2020'

Europe's Columbus science module was attached to the ISS in 2008

From The BBC:

Europe wants a decision in 2010 on an extension to the life of the International Space Station (ISS).

At the moment, no programme for its use nor any funding has been put in place to support the platform beyond 2015.

But the European Space Agency's (Esa) Director General, Jean-Jacques Dordain, told the BBC the uncertainty was undermining best use of the ISS.

Longest Solar Eclipse For 1,000 Years Turns Sun Into A Blazing Ring Of Fire

The skies over Hongdao, China, where the spectacular 'ring of fire' could be seen. The eclipse was annular, meaning the Moon blocked most of the Sun's middle

From The Daily Mail:

Millions of people were plunged into darkness today as the longest solar eclipse for 1,000 years turned the Sun into a blazing ring of fire.

Such a spectacle will not be seen again until December 23rd, 3043.

Unlike eclipses which block out the Sun entirely this one was annular meaning the Moon blocked most of the Sun's middle, but not its edges, causing it to look like a circular band of light.

From The Independent:

Drunkenness, hangovers, and debauchery tend to come to mind when one thinks about alcohol and its effects. But could alcohol also have been a catalyst for human civilization?

According to archaeologist Patrick McGovern this may have been the case when early man decided to start farming. Why humans turned from hunting and gathering to agriculture could be the result of our ancestors’ simple urge for alcoholic beverages.

From The Globe And Mail:

Action is needed at the global level to ensure that cyberspace doesn't slip into a new dark age

Google's announcement that it had been hit by cyberattacks from China and that it's reconsidering its services in that country has smacked the world like a thunderclap: Why the drastic move? How will China respond? Will other companies with interests in China, such as Microsoft and Yahoo, follow suit? What does it mean for the future of cyberspace?

Some may be puzzled. How does Google's decision to end censored search services in China relate to the attacks on its infrastructure, the theft of intellectual property and access to private e-mail accounts? Well, there are connections. Censorship, surveillance and information warfare are part of an emerging storm in cyberspace in which countries, corporations and individuals are vying for control.

From CNET News:

One of NASA's seemingly immortal Mars rovers might soon be at the end of its days.

The Spirit rover had been cruising around the Red Planet, along with its companion, Opportunity, since they both arrived six years ago this month. (Spirit landed on January 3, 2004, while Opportunity landed on January 24 of that year.) Their mission to send back photos and data about the Martian surface was expected to last a mere 90 days. Instead, the two traveling research bots blew away all expectations, continuing their treks year after year.

Poker Paradox: The More Hands You Win, The More Money You Lose

From Science A Gogo:

Analyzing more than 27 million hands of No-Limit Texas Hold'em, a Cornell researcher has found that the more hands players win, the less money they're likely to collect - especially when it comes to novice players. The study was published in the Journal of Gambling Studies.

Cornell's Kyle Siler hypothesizes that the multiple wins are likely for small stakes, and the more you play, the more likely you will eventually be walloped by occasional - but significant - losses. "[The finding] coincides with observations in behavioral economics that people overweigh their frequent small gains vis-à-vis occasional large losses, and vice versa," Siler explained. In other words, players feel positively reinforced by their streak of wins but have difficulty fully understanding how their occasional large losses offset their gains.

From Science Daily:

Science Daily (Jan. 14, 2010) — Astronomers from the California Institute of Technology (Caltech) and other institutions, using the highly sensitive 10-meter Keck I telescope atop Hawaii's Mauna Kea, have detected an extrasolar planet with a mass just four times that of Earth. The planet, which orbits its parent star HD156668 about once every four days, is the second-smallest world among the more than 400 exoplanets (planets located outside our solar system) that have been found to date. It is located approximately 80 light-years from Earth in the direction of the constellation Hercules.

Airport Security Unlikely To Spot Hard-to-Find Weapons

a new study found. Credit: StockXpert


From Live Science:

When airport screeners don’t expect to find a gun in your bag, they likely won’t, suggests new research that shows that when people think something will be difficult to find, they don't look as hard as when they think they're likely to see what they're searching for.

Call it the needle-in-the-haystack effect: Humans aren’t adapted to finding rare things.

"We know that if you don't find it often, you often don't find it," said cognitive scientist Jeremy Wolfe of Harvard Medical School. "Rare stuff gets missed."

From Time Magazine:


Last January a team of scientists at the World Health Organization (WHO) published a study in the British medical journal the Lancet making the audacious claim that the tools already exist to end the AIDS epidemic. Doctors have long noted that antiretrovirals — the drugs commonly used to treat HIV — are so successful at suppressing the number of viruses in an infected patient's blood that they can render a person no longer contagious. Using mathematical models, the researchers claimed that universal HIV testing followed by the immediate treatment of newly infected patients with antiretroviral drugs could eliminate the disease from even the most heavily infected populations within 10 years.

Herschel Space Telescope Restored To Full Health

From The BBC:

Europe's billion-euro Herschel Space Telescope is fully operational again after engineers brought its damaged instrument back online.

The observatory's HiFi spectrometer was turned off just three months into the mission because of an anomaly that was probably triggered by space radiation.

The Dutch-led consortium that operates HiFi has now switched the instrument across to its reserve electronics.

Marvels From Mars: Stunning Postcards From The Red Planet

Devil's punch bowl? The mouth of Albor Tholus, an extinct volcano, is 30km across

From The Daily Mail:

The Red Planet, Mars, fascinates us like no other celestial body. We have yet to visit the most Earth-like world in the solar system in person, but since the Sixties a small armada of space probes have poked and prodded the dusty Martian surface.

And, as these astonishing images show, they have taken the most spectacular close-up pictures while orbiting the planet.

Because Mars has so little air, and certainly no substantial running water and no vegetation, the processes of weathering and erosion, so important on Earth, operate differently on Mars.

Government Gmail Use Following Google's China News

From ZNet:

Updated: A Google spokesman responds with the following: The premise of Mr. Strassmann’s post is without merit: There’s no need to withdraw servers that store Gmail information from China because there aren’t any there.

Federal Chief Information Officer Vivek Kundra has been a consistent advocate of increasing the government’s use of commercially available technologies, such as Gmail. In fact, as the District of Columbia’s chief technology officer, Kundra implemented Google Apps, including Gmail, for all District employees.

From New Scientist:

A major Antarctic glacier has passed its tipping point, according to a new modelling study. After losing increasing amounts of ice over the past decades, it is poised to collapse in a catastrophe that could raise global sea levels by 24 centimetres.

Pine Island glacier (PIG) is one of many at the fringes of the West Antarctic ice sheet. In 2004, satellite observations showed that it had started to thin, and that ice was flowing into the Amundsen Sea 25 per cent faster than it had 30 years before.

Why China Needs Google More Than Google Needs China

From Popular Mechanics:

Cyber attacks targeting Gmail accounts of Chinese human right activists have led to a decision by Google to relax self-censorship for China. This may be the first step in a much larger pullout from China by tech giant Google. This bold business move is a good thing, according to Popular Mechanics's senior technology editor, Glenn Derene. Here, Derene argues that China needs Google's innovation and creativity much more than Google needs Chinese business.

DARPA Spends $51 Million On Matrix-Like Cyber War Firing Range

Do Virtual IT Administrator Opponents Dream Of Electric Jolt Cola Bottles? via Chas Andrews

From Popular Science:

As any soldier will tell you, consistent and realistic drill forms the foundation of any successful military action. But whereas an infantryman can hone his aim at a firing range, America's Internet warriors don't have a similar venue for developing their skills at cyberwar. But DARPA hopes a $51 million network simulation, complete with computer programs that behave like human targets and adversaries, will provide the perfect arena for developing the next generation of cyberwar weapons and tactics.
