From Popular Mechanics:

The United States military's attempts to track down Osama bin Laden in the seven-plus years since the World Trade Center attacks have been notoriously fruitless. But a new study suggests the way to find America's most wanted criminal is to treat him like an endangered species. In the study, released in MIT International Review, University of California-Los Angeles geographers Thomas Gillespie and John Agnew modeled the terrorist leader's possible whereabouts by using the same techniques conservationists use to track the dispersal of animals and likely migration patterns. Using a variety of criteria specific to Osama bin Laden's needs—electricity, room for his entourage, health problems—the study isolates three buildings in the remote Pakistani town of Parachinar in the Federally Administered Tribal Areas as the most likely hideout. (The paper was submitted to the FBI before it went to the MIT journal and, according the FBI, it was forwarded to the appropriate personnel and is part of an active investigation.)

Just How Fat Are We?

Big Little Kids: Obesity rates in Americans ages 12 to 19 have more than tripled since 1980.

From Popsci.com:

Headlines fret about the growing obesity epidemic, but what does it mean? How did it happen? And what are the costs?

Obesity, defined as a body-mass index (BMI) of 30 or higher, is not equally distributed across the U.S. Check out this map to find out which state is the fattest (hint: it's the namesake of mud pie), which is the thinnest (think Coors Light), and which spends the most money on obesity-related health care (its governor pumps iron).

Read on, after the break, for more of America's (and the world's) fat facts.

Are We Lost? Why Women Are Worse At Reading Maps But Can Find Those Misplaced Keys -- Daily Mail

Women are worse at reading maps but better at finding lost items, research into how the sexes perceive beauty has revealed.

U.S Scientists asked 10 men and 10 women to view a series of unfamiliar pictures. The participants were told to give their impressions of the images and whether or not they found them beautiful.

The scientists also used a technique called magnetoencephalography (MEG) to measure changes in the magnetic fields generated by active neurons in the brain.

When Dreaming Is Believing: Dreams Affect People's Judgment, Behavior

From Science Daily:

Science Daily (Feb. 22, 2009) — While science tries to understand the stuff dreams are made of, humans, from cultures all over the world, continue to believe that dreams contain important hidden truths, according to newly published research.

In six different studies, researchers surveyed nearly 1,100 people about their dreams. "Psychologists' interpretations of the meaning of dreams vary widely," said Carey Morewedge, an assistant professor at Carnegie Mellon University and the study's lead author. "But our research shows that people believe their dreams provide meaningful insight into themselves and their world."

Is The Internet Warping Our Brains?

Image from Esther's Space

From Live Science:

The Internet is no doubt changing modern society. It has profoundly altered how we gather information, consume news, carry out war, and create and foster social bonds. But is it altering our brains? A growing number of scientists think so, and studies are providing data to show it.

What remains to be seen is whether the changes are good or bad, and whether the brain is, as one neuroscientist believes, undergoing unprecedented evolution.

From The Independent:

It's green, about 300,000 miles wide and some 38 million miles away, and tonight a comet called Lulin could be visible to the naked eye.

At around midnight, UK space scientists and amateur stargazers will be looking due south for a glimpse of the unusual celestial body as it reaches its nearest point to Earth.

Discovered only a year ago, the comet gets its green colour from a poisonous, cyanide-like gas in its atmosphere.

NASA Says Climate Satellite Fails To Launch

From Yahoo News/Reuters:

WASHINGTON (Reuters) – A mission carrying a climate satellite into orbit failed on Tuesday when the satellite was not able to separate from the rocket, NASA said.

"The vehicle ... landed just sort of Antarctica in the ocean," John Brunschwyler of Virginia-based Orbital Sciences Corp, which made the rocket told a news conference.

The $278 million Orbiting Carbon Observatory was going to measure carbon dioxide in the atmosphere and to determine what happens to the climate-changing pollutant.

Most Detailed Lunar Map Suggests Little Water Inside Moon

An international team of researchers has created the most detailed map of the Moon yet, using the laser altimeter (LALT) instrument on board the Japanese Selenological and Engineering Explorer satellite. C.K. Shum, professor of earth sciences at Ohio State University, is a member of the LALT science team and a co-author of a paper appearing in the February 13 issue of the journal Science.

From Science Daily:

ScienceDaily (Feb. 23, 2009) — The most detailed map of the Moon ever created has revealed never-before-seen craters at the lunar poles.

The map is also revealing secrets about the Moon's interior -- and hinting about Mars's interior as well.

C.K. Shum, professor of earth sciences at Ohio State University, is part of the international research team that published the map in the February 13 issue of the journal Science.

"The surface can tell us a lot about what's happening inside the Moon, but until now mapping has been very limited," Shum said. "For instance, with this new high-resolution map, we can confirm that there is very little water on the Moon today, even deep in the interior. And we can use that information to think about water on other planets, including Mars."

Unlike Diamonds, Most Minerals Not Forever

From Live Science:

Diamonds may be forever, but that's not true of most minerals. In fact, about two-thirds of the 4,300 known minerals on Earth today owe their existence to biological processes, and thus evolved fairly recently in geological terms. So says Robert M. Hazen of the Carnegie Institution in Washington, D.C., who with seven colleagues identified three phases of mineral evolution.

The first phase began more than 4.55 billion years ago, as the solar system started developing. Chemical elements came together, forming about 250 simple minerals that in turn coalesced into planets. On Earth, the second phase stretched from 4.55 billion to 2.5 billion years ago, starting with the violent collision that formed the Moon. Earth's temperature and pressure varied wildly; plate tectonics began churning the planet's surface; and volatiles appeared, such as water and carbon dioxide, helping to redistribute the elements. Those changes enabled the evolution of some 1,250 new minerals.

From MSNBC/AP:

First cell of synthetic life can only be seen under a microscope.

WASHINGTON - Around the world, a handful of scientists are trying to create life from scratch and they’re getting closer.

Experts expect an announcement within three to 10 years from someone in the now little-known field of “wet artificial life.”

“It’s going to be a big deal and everybody’s going to know about it,” said Mark Bedau, chief operating officer of ProtoLife of Venice, Italy, one of those in the race. “We’re talking about a technology that could change our world in pretty fundamental ways — in fact, in ways that are impossible to predict.”

Six Ways to Boost Brainpower

Image Composition By Scientific American Mind; Julie Felton Istockphoto (barina); Dean Turner Istockphoto (background)

From Scientific American:

Key Concepts

* Scientists are finding that the adult human brain is far more malleable than they once thought. Your behavior and environment can cause substantial rewiring of your brain or a reorganization of its functions.
* Studies have shown that exercise can improve the brain’s executive skills, which include planning, organizing and multitasking. What you eat can also influence how effectively your brain operates.
* Activities such as listening to music, playing video games and meditating may boost cognitive performance as well.

Amputees sometimes experience phantom limb sensations, feeling pain, itching or other impulses coming from limbs that no longer exist. Neuroscientist Vilayanur S. Ramachandran worked with patients who had so-called phantom limbs, including Tom, a man who had lost one of his arms.

Ramachandran discovered that if he stroked Tom’s face, Tom felt like his missing fingers were also being touched. Each part of the body is represented by a different region of the somatosensory cortex, and, as it happens, the region for the hand is adjacent to the region for the face. The neuroscientist deduced that a remarkable change had taken place in Tom’s somatosensory cortex.

India Approves £1.7bn Plan To Launch Astronauts As Asian Space Race Heats Up -- Times Online

India has approved a £1.7 billion plan to launch its first astronauts into space by 2015, in its latest bid to close the gap with China in what many see as a 21st Century Asian version of the Cold War race for the Moon.

The Indian Space Research Organisation (ISRO) will attempt to put two people into orbit 172 miles (275 km) above the Earth for seven days, according to a proposal approved by the Planning Commission at a meeting on Friday.

"ISRO needs to be supported as it has done marvellous job in the field of Space Science. That's why Planning Commission will support it," Montek Singh Ahluwalia, Deputy Chairman of the Planning Commission, told reporters.

"An unmanned flight will be launched in 2013-2014 and manned mission likely to launch by 2014-2015," he said.

Aging Mars Rover Gets A Power Boost

Mars rover Spirit

From Yahoo News/Space:

NASA's aging Mars rover Spirit has a bit more power under its hood thanks to some Martian winds that cleaned dust from its vital solar panels.

The handy cleaning occurred earlier this month and was discovered by engineers scanning data from Spirit's power subsystem.

"We will be able to use this energy to do significantly more driving," said Colette Lohr, a rover mission manager at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif. "Our drives have been averaging about 50 minutes, and energy has usually been the limiting factor. We may be able to increase that to drives of an hour and a half."

Scientists Close In On 'Universal' Vaccine For Flu: Study

From Breitbart/AFP:

Scientists on Sunday unveiled lab-made human antibodies that can disable several types of influenza, including highly-lethal H5N1 bird flu and the "Spanish Flu" strain that killed tens of millions in 1918.

Tested in mice, the antibodies work by binding to a previously obscure structure in the flu virus which, when blocked, sabotages the pathogen's ability to enter the cell it is trying to infect, according to the study.

Because this structure -- described by one scientist as a "viral Achilles' heel" -- is genetically stable and has resisted mutation over time, the antibodies are effective against many different strains.

The 10 Most Influential UFO-Inspired Books, Movies and TV Shows -- Popular Mechanics

UFO culture began in the late 40’s, when a pilot’s account of a midair encounter with mysterious aircraft triggered similar reports across the United States. Authors, movie producers and a few hack journalists were quick to respond. By the late 1950s, pop culture was completely preoccupied with aliens, and the clichés it created then have been repeated and reinvented ever since. Here are the books, TV shows and movies that helped create the mythology of UFOs in America. They aren’t the best, or the worst, but the ones that made the most impact on the prevailing American superstition of our time.
