Mars Rover Spirit's Days May Be Numbered
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
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.

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."

New Study Raises Concerns About HIV-Drug Resistance
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.

Marvels From Mars: Stunning Postcards From The Red Planet
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
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
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
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.

The Exoplanet Explosion
From The Space Review:
Fifteen years ago, there were virtually no known planets beyond the (then nine) planets in our own solar system: just a few found by chance orbiting a pulsar. Then, in late 1995 and 1996, came the initial discovery of planets orbiting main sequence stars like the Sun. That slow trickle of discoveries became a steady stream as astronomers refined their instruments and techniques, as well as increased both the number of stars studied and their period of time observed. By the beginning of 2010 astronomers reported finding over 400 such extrasolar planets, or exoplanets.

Exotic Stars May Mimic big Bang
From New Scientist:
A new class of star may recreate the conditions of the big bang in its incredibly dense core.
Pack matter tightly enough and gravity will cause it to implode into a black hole. Neutron stars were once thought to be the densest form of matter that could resist such a collapse. More recently, physicists have argued that some supernovae may leave behind even denser quark stars, in which neutrons dissolve into their constituent quarks.

Could Haiti's Earthquake Tragedy Have Been Prevented?
From Popular Mechanics:
The 7.0-magnitude earthquake that devastated Haiti was long predicted by one group of geophysicists. Could the tragedy have been prevented?
On January 12, around dinnertime, a 7.0-magnitude earthquake struck Haiti, decimating the island nation and leaving hundreds of thousands presumed dead. A rescue effort is underway now, but as government officials and rescue agencies sort through the rubble, it is worth asking: Could this tragedy have been prevented?

Looking For Life As We Know It
From Cosmos:
Some scientists are convinced life is common in the universe, but intelligence rare. As for how long civilisations last - and stay detectable - few are willing to hazard a guess.
Two young physicists at Cornell University in upstate New York, Philip Morrison and Giuseppe Cocconi, had long been interested in gamma rays. One spring day in 1959, Cocconi posed an intriguing question: wouldn’t gamma rays be perfect for communication between the stars?
The discussion that followed led to a two-page article in the British journal Nature entitled “Searching for interstellar communications”. Sandwiched between a paper on the electronic prediction of swarming in bees and one on metabolic changes induced in red blood cells by X-rays, the duo argued that if advanced extraterrestrial civilisations existed, and wanted to communicate, they would likely use radio.

Haiti Earthquake Science: What Caused The Disaster
From The Live Science:
The major earthquake that struck Haiti Tuesday may have shocked a region unaccustomed to such temblors, but the devastating quake was not unusual in that it was caused by the same forces that generate earthquakes the world over. In this case, the shaking was triggered by much the same mechanism that shakes cities along California's San Andreas fault.
The 7.0-magnitude Haiti earthquake would be a strong, potentially destructive earthquake anywhere, but it is an unusually strong event for Haiti, with even more potential destructive impact because of the weak infrastructure of the impoverished nation.

Google Is Not The Only Internet Site Attacked By China
Dozens of companies, human rights groups targeted in sophisticated strike.
Computer attacks on Google that the search giant said originated in China were part of a concerted political and corporate espionage effort that exploited security flaws in e-mail attachments to sneak into the networks of major financial, defense and technology companies and research institutions in the United States, security experts said.
At least 34 companies — including Yahoo, Symantec, Adobe, Northrop Grumman and Dow Chemical — were attacked, according to congressional and industry sources. Google, which disclosed on Tuesday that hackers had penetrated the Gmail accounts of Chinese human rights advocates in the United States, Europe and China, threatened to shutter its operations in the country as a result.

Google Threatens To Pull Out Of China
From The Telegraph:
Google, the internet search engine, has said it is ready to close down its business and quit China because of the country's increasing censorship.
In a head-to-head confrontation with the Chinese government, the company said that it will pull out of the country unless it is allowed to provide a totally uncensored service.
After the announcement, Google's China website immediately began to offer reports and images of the Tiananmen Square massacre and other highly sensitive events that Beijing has suppressed for decades.

From MSNBC/Cosmic Log:
Do rocks from Mars bear the tiny fossilized signs of life? Scientists who think so say they'll subject meteorites from the Red Planet to a new round of high-tech tests in hopes of adding to their evidence.
For years, only one meteorite has figured in the controversy: ALH84001, a rock that was blasted away from Mars 16 million years ago, floated through space and fell through Earth's atmosphere onto Antarctica about 13,000 years ago. Scientists reported in 1996 that the rock contained microscopic structures that looked like "nano-fossils," but skeptics said the structures could have been created by chemical rather than biological reactions.

How Winning Can Mean Losing In Poker And Life
From Time Magazine:
You can learn a lot about gambling if you're willing to analyze 27 million hands of online poker. Don't have time for that? No worries; sociology doctoral student Kyle Siler of Cornell University has done it for you. His counterintuitive message: the more hands you win, the more money you're likely to lose — and this has implications that go well beyond a hand of cards.
Siler, whose work was published in December in the online edition of the Journal of Gambling Studies and will appear later this year in the print edition, was not interested in poker alone but in the larger idea of how humans handle risk, reward and variable payoffs. Few things offer a better way of quantifying that than gambling — and few gambling dens offer a richer pool of data than the Internet, where millions of people can play at once and transactions are easy to observe and record.

OLED Could Be Apple Tablet’s Secret Solution For E-Reading
From Gadget Lab:
An OLED display would be a pricey, but perfect, screen for e-book reading on a tablet, like the one Apple is rumored to be announcing later this month.
OLEDs are serious power drainers, but if Apple were to implement a reading mode with a black background and light-colored text, then an OLED screen would consume far less energy. That’s because OLEDs consume power differently than LCDs; they only use power when pixels are turned on. That means blacks won’t consume any energy, and such a reading mode would substantially preserve battery life, an analyst told Wired.com.

NASA Feels 'Plutonium Pinch' Earlier Than Expected
From New Scientist:
NASA is feeling the pinch in its plutonium supplies.
Many spacecraft are powered by the radioactive decay of plutonium-238, but the US no longer produces the material. Instead, NASA relies on its shrinking stockpile, topped up with purchases from Russia.
Previous estimates suggested the decline would not affect solar-system exploration until after 2020, but NASA is already tightening its belt. Candidates for NASA's next "New Frontiers" mission, which aims to launch an exploratory spacecraft by 2018, will not be allowed to rely on plutonium for power, effectively limiting the candidate probes to solar power only.

Mystery Object On Course To Whiz Past Earth
From MSNBC/Discovery News:
It will not hit the planet, but scientists aren't sure what it is, exactly.
A near-Earth object that could be human-made has just been discovered hurtling toward us. On Wednesday, the object called 2010 AL30 will fly by Earth at a distance of just 80,000 miles (130,000 kilometers). That's only one-third of the way from here to the moon — that is, very close.
It will miss us, and if it did hit us, it wouldn't do any damage anyway, but I managed to pick up on some chatter between planetary scientists and found out that the "asteroid," or whatever it is, gives us a new standard: A 10-meter-wide (33-foot-wide) asteroid can be detected two days before it potentially hits Earth. A pretty useful warning, if you ask me.

Brain 'Entanglement' Could Explain Memories
'tipping point' of activity (Image: Stone/Getty)
From The New Scientist:
Subatomic particles do it. Now the observation that groups of brain cells seem to have their own version of quantum entanglement, or "spooky action at a distance", could help explain how our minds combine experiences from many different senses into one memory.
Previous experiments have shown that the electrical activity of neurons in separate parts of the brain can oscillate simultaneously at the same frequency – a process known as phase locking. The frequency seems to be a signature that marks out neurons working on the same task, allowing them to identify each other.
