From Science Daily:

Science Daily (Jan. 6, 2010) — Radio astronomers have uncovered 17 millisecond pulsars in our galaxy by studying unknown high-energy sources detected by NASA's Fermi Gamma-ray Space Telescope. The astronomers made the discovery in less than three months. Such a jump in the pace of locating these hard-to-find objects holds the promise of using them as a kind of "galactic GPS" to detect gravitational waves passing near Earth.

From Live Science:

Mother Nature offers up a cacophony of diverse sounds. But after examining the calls of hundreds of species from cricket chirps to chimp hoots, scientists have found they aren't so different from one another.

Their research on the calls made by nearly 500 animal species has led to simple mathematical models that can predict an animal's sounds based on the rate at which that individual takes up and uses energy.

From Cosmos:

SYDNEY: Habitable alien moons such as 'Pandora' – the world featured in the blockbuster film Avatar – could be detectable within a decade, says a new study.

In that movie, the fictional, life-harbouring moon is found orbiting a gas giant called Polyphemus, which itself orbits the star Alpha Centauri A.

NASA's Kepler Mission has already shown the potential to detect Earth-sized planets within the Milky Way (see "Kepler telescope finds five new exoplanets").

From New Scientist:

A giant planet with the density of Styrofoam is one of a clutch of new exoplanets discovered by NASA's Kepler telescope. The planets are too hot to support life as we know it, but the discoveries, made during the telescope's first few weeks of operation, suggest Kepler is on the right track to find Earth's twins, researchers say.

More than 400 planets have now been found orbiting other stars, but Earth-sized planets – which may be the best habitats for life – have remained elusive.

Where Is El Niño When We Need Him?

From Discovery News:

Just when we might be expecting the influence of unusually high Pacific ocean temperatures to warm us up -- or for global warming to bring relief -- along comes another wave of incredibly cold storms. How the season finally turns out is still up in the air, so to speak, but clearly, that weather patterns that are typical of El Niño have not taken hold across the United States.

And it's easy to forget that global warming is a long-term climate trend that has little to do with individual seasons in one part of the world or another. In fact, it might be hard to appreciate just now, but the year just ended -- 2009 is a single data point -- actually came in a little warmer than the two years before and is fairly close to the middle range of model simulations of the long-term trend that has provoked international scientific concern about global warming.

Pi Calculated To 'Record Number' Of Digits

From The BBC:

A computer scientist claims to have computed the mathematical constant pi to nearly 2.7 trillion digits, some 123 billion more than the previous record.

Fabrice Bellard used a desktop computer to perform the calculation, taking a total of 131 days to complete and check the result.

This version of pi takes over a terabyte of hard disk space to store.

Previous records were established using supercomputers, but Mr Bellard claims his method is 20 times more efficient.

The prior record of about 2.6 trillion digits, set in August 2009 by Daisuke Takahashi at the University of Tsukuba in Japan, took just 29 hours.

However, that work employed a supercomputer 2,000 times faster and thousands of times more expensive than the desktop Mr Bellard employed.

C.I.A. Is Sharing Data With Climate Scientists

A satellite image of East Siberian Sea from 1999-2008. This image has been degraded
to hide the satellite’s true capabilities. USGS

From The New York Times:

The nation’s top scientists and spies are collaborating on an effort to use the federal government’s intelligence assets — including spy satellites and other classified sensors — to assess the hidden complexities of environmental change. They seek insights from natural phenomena like clouds and glaciers, deserts and tropical forests.

The collaboration restarts an effort the Bush administration shut down and has the strong backing of the director of the Central Intelligence Agency. In the last year, as part of the effort, the collaborators have scrutinized images of Arctic sea ice from reconnaissance satellites in an effort to distinguish things like summer melts from climate trends, and they have had images of the ice pack declassified to speed the scientific analysis.

Can Full-Body Airport Scanners Harm You?

The scanners are supposed to be the high-tech version of a physical pat-down.
(Credit: TSA)

From CNET:

Since explosive materials were sneaked onto a U.S. domestic flight on Christmas Day, full-body scanning machines are far more likely to make their way to security lines at your local airport, even though they might not have detected said materials.

While the Transportation Security Administration already has 40 such devices in place, it just bought 150 to be placed in U.S. airports and says it plans to buy 300 more (they go for $170,000 apiece). On Wednesday, the Netherlands announced that these scanners would be used on passengers for all flights out of Amsterdam to the U.S., and there is talk of scanners in Nigeria as well.

New Exoplanet Hunter Makes First 5 Discoveries

From Wired Science:

The Kepler Space Telescope, a designated planet-hunting satellite, has found its first five planets, among them an odd, massive world only as dense as Styrofoam.

The number of planets now known outside the solar system has risen to more than 400, but none is yet Earth-like enough to harbor life. Right now, Kepler can only detect large planets orbiting close to their stars, which means that these first planets are too hot to hold liquid water, a requirement for life as we know it.

But over the next year, the mission’s scientists will be homing in on ever more life-friendly places.

Precious Metals That Could Save The Planet

The Rare Earth Research Institute is in Baotou City, above,
in the Autonomous Region of Inner Mongolia, China

From The Independent:

Rare earth elements are driving a revolution in low-carbon technology. Cahal Milmo reports on the commodity that has become the new oil.

Baotou was of little interest to the outside world for millennia. When one of the first visitors reached its walls in 1925, it was described as "a little husk of a town in a great hollow shell of mud ramparts". Some 84 years later, this once barren outpost of Inner Mongolia has been transformed into the powerhouse of China's dominance of the market in some of the globe's most sought-after minerals.

From New Scientist:

PEOPLE have radically diverse responses to the very idea of conspicuous consumption. Some folks consider it blindingly obvious that most economic behaviour is driven by status seeking, social signalling and sexual solicitation. These include most Marxists, marketers, working-class fundamentalists and divorced women. Other folks consider this an outrageously cynical view, and argue that most consumption is for individual pleasure ("utility") and family prosperity ("security"). Those folks include most capitalists, economists, upper-class fundamentalists, and soon-to-be-divorced men.

2009’s Sleepy Sun Finally Woke Up In December

From Wired Science:

2009 will go down as the sun’s third quietest year on record, under-shone only by 1913 and 2008.

Two hundred-sixty of the year’s 365 days (71 percent) were sunspotless. Last year saw 266 sunspotless days, while the sun had no spots on 311 of the days in 1913. It was only a very active December that kept 2009 from falling below last year’s mark.

Sunspot activity waxes and wanes in a roughly 11-year cycle, so hitting solar minima isn’t surprising. But what the numbers underscore is that we spent much of the year still in the midst of the deepest, longest solar minimum in a long time.
