From New Scientist:

A complex form of mathematical symmetry linked to string theory has been glimpsed in the real world for the first time, in laboratory experiments on exotic crystals.

Mathematicians discovered a complex 248-dimensional symmetry called E8 in the late 1800s. The dimensions in the structure are not necessarily spatial, like the three dimensions we live in, but they correspond to mathematical degrees of freedom, where each dimension represents a different variable.

Fire Holds No Fears For Chimps, Says Scientist

Observations of chimpanzees could shed light on when our human ancestors first controlled fire. Andrew Aiken / Rex Features

From The Independent:

But did the early ancestor of Man learn how to control it?

Wild chimpanzees have been observed carrying out a “fire dance” in front of grassland wildfires as part of a suite of unusual behaviours that could indicate an ability of man’s closet living relative to understand and even control fire.

Instead of fleeing the wildfires in panic, the chimps were seen to monitor them carefully, showing no signs of the fear that other animals normally exhibit. Their leader – the alpha male – was even observed performing a ritualistic display while facing the flames.

Electromagnetic Manufacturing: It's A Knockout

From The Economist:

Engineers find a new way to punch holes through steel.

ELECTROMAGNETIC pulses (EMPs) are usually associated with warfare. The idea is to use a blast of energy to fry the enemy’s computers and telecommunications gear. One common way proposed to do this is with an atomic bomb. In a less extreme fashion, however, EMPs have peaceful uses. They are already employed industrially to shape soft and light metals, such as aluminium and copper. Now a group of researchers at the Fraunhofer Institute for Machine Tools and Forming Technology in Chemnitz, Germany, has found a way to use an EMP device to shape and punch holes through industry’s metallic heavyweight—steel. This could transform manufacturing by doing away with the need to use large, heavy presses to make goods ranging from cars to washing machines.

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.

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.

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.

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

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:

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.
