Neuron Breakthrough Offers Hope On Alzheimer’s And Parkinson’s
From Times Online:
Neurons have been created directly from skin cells for the first time, in a remarkable study that suggests that our biological makeup is far more versatile than previously thought.
If confirmed, the discovery that one tissue type can be genetically reprogrammed to become another, could revolutionise treatments for conditions such as Parkinson’s disease and Alzheimer’s, opening up the possibility of turning a patient’s own skin cells into the neurons that they need.

NASA Sets Feb. Launch Date For Shuttle Endeavour
From ABC News:
NASA sets Feb. 7 launch date for shuttle Endeavour, delivering new space station room.
NASA has set an early February launch date for space shuttle Endeavour.
Senior managers met Wednesday and decided unanimously to proceed toward a Feb. 7 launch date for Endeavour. It will be a pre-dawn liftoff at 4:39 a.m. — in all probability the last shuttle launch in darkness.
Endeavour will carry up a new room and observation deck for the International Space Station, the last of the major U.S. components. The six-person crew will hook up the chamber, named Tranquility, during a series of spacewalks.

Shoes May Have Changed How We Run
From The BBC:
Wearing cushioned running shoes may have changed the way in which many of us run, new research suggests.
Using slow-motion footage, scientists have discovered that experienced barefoot runners land very differently from runners who wear shoes.
The researchers showed that runners who have trained barefoot tend to strike the ground with their forefoot or mid-foot, rather than their heel.

3-D Glasses Get A Makeover
The Bocko family of Bernardston, Mass., tried watching "The Polar Express" on Christmas Day with paper 3-D glasses but gave up partway through because the glasses weren’t fitting well enough for them to enjoy the full effect. Joanne Ciccarello/Staff
From Christian Science Monitor:
New home entertainment technology aims to transform a 3-D viewer’s experience.
It seems every year is heralded as “the year 3-D home entertainment will take off.” Yet the moment never really arrives.
Last year saw huge strides for 3-D movies in theaters. Each of the seven top-grossing 3-D movies of all time came out in 2009. Atop the list sits “Avatar,” which raked in more than $1.6 billion worldwide and became history’s second biggest box-office hit in only a few weeks. And animation powerhouse Pixar, hungry for similar successes, stuck to its pledge to only make 3-D movies from now on.
This is great news for theatergoers, but there are very few ways to bring the extra dimension home with you.

New Theory of Primate Origins Sparks Controversy
From Live Science:
The evolution of the distant ancestors of humans and other primates may have been driven by dramatic volcanic eruptions and the parting of continents, according to a controversial new theory.
Scientists remain skeptical about the idea, however.
According to prevailing theories, primates originated in a small area. From this center of origin, they dispersed to other regions and continents.

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.

India Plans Manned Space Mission In 2016
From Breitbart/AFP:
India will launch its first manned space mission in 2016 in a bid to match space pioneers such as Russia and the United States, a top official said Wednesday.
The government had already approved plans for a human space flight project by the Indian Space Research Organisation (ISRO), and last year gave the go-ahead for funding of around 2.8 billion dollars.
ISRO chairman K. Radhakrishnan said the agency would develop the space module for the programme within four years.

Blonde Women Born To Be Warrior Princesses
Photo: Blondes, such as the actress Emilia Fox, are used to having their own way, the study says
From 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.

From Times Online:
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.

From E! Science News:
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
From 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.
