Video: Boeing's Truck-Mounted Laser Neatly Picks Off 50 IEDs In A Row
From Popular Science:
Boeing's laser weapons have already shown the power to blast aerial drones from the sky, but may find even more immediate use in detonating roadside bombs, which are a top killer of soldiers deployed in Iraq and Afghanistan. A newly unveiled video shows the company's truck-mounted Laser Avenger destroying two improvised explosive devices (IEDs) during a series of 50 test firings that took place at Redstone Arsenal in Huntsville, Alabama last September, according to OptoIQ.

Blonde Women Born To Be Warrior Princesses
Photo: Blondes, such as the actress Emilia Fox, are used to having their own way, the study saysFrom Times Online:
IT really is a case of blonde ambition. Women with fair hair are more aggressive and determined to get their own way than brunettes or redheads, according to a study by the University of California.
Researchers claim that blondes are more likely to display a “warlike” streak because they attract more attention than other women and are used to getting their own way — the so-called “princess effect”.
Even those who dye their hair blonde quickly take on these attributes, experts found.

The university at the centre of the climate change row over stolen e-mails broke the law by refusing to hand over its raw data for public scrutiny.
The University of East Anglia breached the Freedom of Information Act by refusing to comply with requests for data concerning claims by its scientists that man-made emissions were causing global warming.
The Information Commissioner’s Office decided that UEA failed in its duties under the Act but said that it could not prosecute those involved because the complaint was made too late, The Times has learnt. The ICO is now seeking to change the law to allow prosecutions if a complaint is made more than six months after a breach.

The most common reasons for medical evacuation of military personnel from war zones in Iraq and Afghanistan in recent years have been fractures, tendonitis and other musculoskeletal and connective tissue disorders, not combat injuries, according to results of a Johns Hopkins study published January 22 in the Lancet. "Most people think that in a war, getting shot is the leading cause of medical evacuation, but it almost never is," says study leader Steven P. Cohen, M.D., associate professor of anesthesiology at the Johns Hopkins University School of Medicine and a colonel in the U.S. Army Reserves. "As in the past, disease and non-battle-related injuries continue to be the major sources of service-member attrition and that's not likely to change. It's likely to get worse."

My Comment: The same can be said about a good percentage of fatalities in war zones. Fatal accidents have always comprised a good percentage of those who are located in conflict zones.

Mysterious Band Of Particles Holds Clues To Solar System's Future
IBEX spacecraft's all-sky map reveals a bright ribbon of particles. Credit: NASAFrom Cosmos:
HUNTSVILLE, USA: The ribbon of particles at the edge of the Solar System "shocked" NASA researchers when it was discovered last year. Now they say it is a reflection off a strong galactic magnetic field, and holds the clues to the future of the Solar System.
In October last year, NASA's IBEX (Interstellar Boundary Explorer) spacecraft made the first all-sky maps of the heliosphere - the bubble of magnetism that springs from the Sun and surrounds our Solar System.
The result was a map bisected by a bright, winding ribbon of unknown origin. At the time, NASA researchers called it a "shocking result" and puzzled over its origin.

Navy Pledges Green Strike Group By 2012
The Navy is Going Green The Navy will demonstrate a Green Strike Group, like the George Washington Carrier Strike Group pictured here, by 2012; the group will run on biofuels and nuclear power rather than fossil fuels. From Popular Science:
Militaries have a tough, often messy job to do, and as such taking steps to polish their green credentials generally isn’t a high priority. But the potential cost savings – not to mention the tactical advantages – of going green are not lost on U.S. Armed Forces’ top brass. The Army has pursued “zero footprint” base camps, and the Air Force is looking into a variety of alternative propellants that could be turned into jet fuel. Now the Navy is going green, signing a memorandum of understanding with the USDA to demo a Green Strike Group of biofuel- and nuclear-powered vessels by 2012.

My Comment: Political correctness running amok .... but I will concede that the search for alternative fuels and energy is a valid one, and one that may produce huge savings in the future (maybe).
Obama Aims To Ax Moon Mission
From Orlando Sentinel:
NASA's plans to return astronauts to the moon are dead. So are the rockets being designed to take them there — that is, if President Barack Obama gets his way.
When the White House releases his budget proposal Monday, there will be no money for the Constellation program that was supposed to return humans to the moon by 2020. The troubled and expensive Ares I rocket that was to replace the space shuttle to ferry humans to space will be gone, along with money for its bigger brother, the Ares V cargo rocket that was to launch the fuel and supplies needed to take humans back to the moon.
There will be no lunar landers, no moon bases, no Constellation program at all.

Science Chief John Beddington Calls For Honesty On Climate Change
The IPCC's 2007 report that the glaciers would disappear by 2035 has exposed a wider problem with the way that some evidence was presentedFrom Times Online:
The impact of global warming has been exaggerated by some scientists and there is an urgent need for more honest disclosure of the uncertainty of predictions about the rate of climate change, according to the Government’s chief scientific adviser.
John Beddington was speaking to The Times in the wake of an admission by the Intergovernmental Panel on Climate Change (IPCC) that it grossly overstated the rate at which Himalayan glaciers were receding.

We Will Find 'Twins Of Earth' This Year, Says Astronomer Michel Mayor
From Times Online:Scientists will have detected the first truly Earth-like planet outside the solar system by the end of the year, one of the world’s leading astronomers predicted yesterday.
Professor Michel Mayor, of Geneva University, who led the team that discovered the first extrasolar planet (or exoplanet) in 1995, said he was confident that a planet of a similar size and composition to Earth would be found in the near future.
Addressing a Royal Society conference to mark the 50th anniversary of the Search for Extra-Terrestrial Intelligence (SETI) programme, he said: “The search for twins of Earth is motivated by the ultimate prospect of finding sites with favourable conditions for the development of life. We’ve entered a new phase in this search.”

TENTACLED monsters, pale skinny humanoids, shimmery beings of pure energy... When it comes to the question of what alien life forms might look like, we are free to let our imagination roam. The science-in-waiting of extraterrestrial anatomy has yet to acquire its first piece of data, so nobody knows what features we will behold if and when humans and aliens come face-to-face. Or face to squirmy something.

Ambassador Or Slave? East Asian Skeleton Discovered In Vagnari Roman Cemetery
Researchers announced that the skeleton of a man, seen here, has DNA that indicates an East Asian ancestry. Sadly he may have been a slave. His sole surviving grave good, a single pot, can be seen on the far left. A person was buried on top of him and appears to have been given more grave goods. Photo courtesy Professor Tracy Prowse.From The Independent:
A team of researchers announced a surprising discovery during a scholarly presentation in Toronto last Friday. The research team, based at McMaster University in Hamilton, Canada, has been helping to excavate an ancient Roman cemetery at the site of Vagnari in southern Italy. Led by Professor Tracy Prowse, they’ve been analyzing the skeletons found there by performing DNA and oxygen isotope tests.
The surprise is that the DNA tests show that one of the skeletons, a man, has an East Asian ancestry – on his mother’s side. This appears to be the first time that a skeleton with an East Asian ancestry has been discovered in the Roman Empire.
However, it seems like this contact between east and west did not go well.

Seniors Have Rewarding Sex Lives
From Live Science:
Senior citizens often have rewarding sex lives, according to new research aimed at revealing the nuances of sexuality in the elderly.
The findings from a set of studies showed that older men between the ages of 57 and 85 are more likely than older women to be sexually active and open. The intimacy of sex, however, was found to be important to both men and women across all ages.
And just as in younger adults, healthy sex means healthy senior citizens.
