From Popular Science:

In an attempt to shorten the gap between the end of the Space Shuttle and the deployment of its replacement, Senator Kay Bailey Hutchison (R-Texas) has introduced a bill that would extend the life of the Shuttle by two years. The bill directly contradicts the White House's space policy, which favors a rapid decommissioning of the Shuttle, followed by an emphasis on the private sector to maintain support of the International Space Station (ISS).

From The New Scientist:

If you want to live to a grand old age, then smile – and make sure you mean it. Pro baseball players in the 1950s who genuinely beamed in their official photographs tended to outlive more sullen-looking sportsmen and those who put on fake smiles.

Players from the US major league with honest grins lived an average of seven years longer than players who didn't smile for the camera and five years longer than players who smiled unconvincingly, conclude Ernest Abel and Michael Kruger at Wayne State University in Detroit, Michigan.

From The Guardian:

Carole Jahme shines the cold light of evolutionary psychology on readers' problems. This week: bad boys.

From a nice girl, aged 37
Dear Carole, Why do girls – even nice girls – fall for bad boys, even when the girls in question are 37 and should know much better? My friends and I don't understand ourselves.

Carole replies:
The "dark triad" of human behaviour consists of narcissism (or self-obsession), psychopathy (including callous, impulsive, thrill-seeking, risk-taking behaviour) and Machiavellianism (exploitative, manipulative and deceitful behaviour). Bad boys exhibit dark triad traits and their behaviour, according to one theory, is genetic, meaning they are unlikely to change their ways.

From Technology Review:

The dream of personalized medicine was one of the driving forces behind the 13-year, $3 billion Human Genome Project. Researchers hoped that once the genetic blueprint was revealed, they could create DNA tests to gauge individuals' risk for conditions like diabetes and cancer, allowing for targeted screening or preëmptive intervention. Genetic information would help doctors select the right drugs to treat disease in a given patient. Such advances would dramatically improve medicine and simultaneously lower costs by eliminating pointless treatments and reducing adverse drug reactions.

From The Daily Mail:

The potent greenhouse gas methane, is bubbling out of the frozen Arctic much faster than expected and could stoke global warming.

Methane had become trapped in the permafrost over time and now 8million tonnes of it is seeping out due to rising temperatures, researchers said today.

'Subsea permafrost is losing its ability to be an impermeable cap,' Natalia Shakhova, a scientist at the University of Fairbanks, Alaska, said in a statement.

She co-led the study published in today's edition of the journal Science.

The Growing Cyberterrorism Threat

FBI Director Warns Of 'Rapidly Expanding' Cyberterrorism Threat -- Washington Post

SAN FRANCISCO -- FBI Director Robert S. Mueller III warned Thursday that the cyberterrorism threat is "real and . . . rapidly expanding."

Terrorists have shown "a clear interest" in pursuing hacking skills, he told thousands of security professionals at the RSA Conference in San Francisco. "They will either train their own recruits or hire outsiders, with an eye toward combining physical attacks with cyberattacks," he said.

Exotic Antimatter Detected at Relativistic Heavy Ion Collider: Heaviest Known Antinucleus Heralds New Frontier In Physics

The diagram above is known as the 3-D chart of the nuclides. The familiar Periodic Table arranges the elements according to their atomic number, Z, which determines the chemical properties of each element. Physicists are also concerned with the N axis, which gives the number of neutrons in the nucleus. The third axis represents strangeness, S, which is zero for all naturally occurring matter, but could be non-zero in the core of collapsed stars. Antinuclei lie at negative Z and N in the above chart, and the newly discovered antinucleus (magenta) now extends the 3-D chart into the new region of strange antimatter.

From Popular Science:

One of the interesting side effects of last year's stimulus bill was $400 million in funding for ARPA-E, the civilian, energy-focused cousin of DARPA. And in this week's first ever ARPA-E conference, MIT chemist Dan Nocera showed how well he put that stimulus money to use by highlighting his new photosynthetic process. Using a special catalyst, the process splits water into oxygen and hydrogen fuel efficiently enough to power a home using only sunlight and a bottle of water.

From New Scientist:

The "theory of everything" is one of the most cherished dreams of science. If it is ever discovered, it will describe the workings of the universe at the most fundamental level and thus encompass our entire understanding of nature. It would also answer such enduring puzzles as what dark matter is, the reason time flows in only one direction and how gravity works. Small wonder that Stephen Hawking famously said that such a theory would be "the ultimate triumph of human reason – for then we should know the mind of God".

Globe-Warning Methane Is Gushing From A Russian Ice Shelf

From Discover Magazine:

Behind the ongoing back-and-forth fights over climate change that usually focus on carbon, there has lingered the threat of the powerful greenhouse gas methane being released into the atmosphere and causing even worse trouble. In August we reported on a study that noted methane bubbling up from the seafloor near islands north of Norway, giving scientists a scare. This week in Science, another team reports seeing the same thing during thousands of observations of the East Siberian Arctic Shelf on Russia’s north coast, which is even more worrisome because it’s a huge methane deposit.
