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.

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.

MIT Satellite Could Trounce Kepler Telescope, Finding Thousands Of Exoplanets In Just Two Years

MIT's Transiting Exoplanet Survey Satellite (TESS) MIT

From Popular Science:

The Kepler Space Telescope made headlines last week when it was announced that the planet-hunting instrument has already found its first five exoplanets. Researchers at MIT, however, think they can do better. A satellite proposed by a team of researchers there could scan a piece of sky 400 times larger than Kepler, observing 2.5 million of the closest stars and discovering hundreds of small exoplanets, several of which may be suitable for life. That is, if NASA decides to build it.

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


Google China Cyberattack Part Of Spy Campaign -- MSNBC/Washington Post

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.

Life On Mars, Continued

iron oxide but with a carbon content slightly greater than the underlying matrix. David McKay / NASA

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

Karen Bleier / AFP / Getty

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.

From The Telegraph:

A Nasa probe has sent back photographs of what appears to be trees on the planet's surface.

The images appear to show rows of dark "conifers" sprouting from dunes and hills on the planet surface. But the scene is actually an optical illusion.

The photographs actually show sand dunes coated with a thin layer of frozen carbon dioxide, or dry ice, less than 240 miles from the planet's north pole.

From The Telegraph:

Women who have plump full lips look younger than their years, scientists have said.

Devotees of collagen injections and silicone implants have long believed it and now research has backed their theory that a bee stung pout can belie their true age.

Even if the woman in question has wrinkles, eye bags, sagging jowels and greying hair, a rosy and firm set of lips will make them appear younger.
