With nearly 1.8 million U.S. soldiers having rotated through Iraq and Afghanistan and another troop escalation expected in coming weeks, researchers are doing double-time to define the causes of Post Traumatic Stress Disorder (PTSD) to better serve troops returning from war. With two wars going and no end in sight, scientists have quite an abundance of subjects on which to carry out their research.
In what can only be described as a harrowing instance of misdiagnosis, a Belgian man presumed comatose for 23 years after a near-fatal car crash was actually conscious and paralyzed the entire time. Rom Houben, whose real state was discovered three years ago but only now made public, could be one of many falsely diagnosed coma cases, raising serious questions about those diagnosed as "vegetative" and, even more frighteningly, the process by which vegetative people are removed from life support.
Through Educate to Innovate, the White House hopes to return American science and technology learning to prominence

Educate to Innovate
Elmo and Big Bird may represent old school learning compared to video games, but both Sesame Street and video game programmers have joined forces as part of a new White House initiative aimed at promoting science, engineering and math both in and out of the classroom.
Talk about a Eureka moment. Scientists at Sandia National Labs, seeking a means to create cheap and abundant hydrogen to power a hydrogen economy, realized they could use the same technology to "reverse-combust" CO2 back into fuel. Researchers still have to improve the efficiency of the system, but they recently demonstrated a working prototype of their "Sunshine to Petrol" machine that converts waste CO2 to carbon monoxide, and then syngas, consuming nothing but solar energy.
Plentiful fat seems more reviled than revered in today's society, even when it has uses for the medical and cosmetic industries. But today police announced the arrest of a Peruvian gang accused of murdering people and selling their fat to the cosmetics industry, according to The Associated Press.
The perils of space flight number in the hundreds, from radiation exposure to the impact of micro-asteroids. But for astronauts who spend an extended amount of time floating weightlessly in the near-endless void of space, muscle atrophy remains the most common health problem. Thankfully, a shipment of RNA-treated worms may help scientists on the International Space Station solve that issue.
In 2009, science got a hefty shot in the arm from the federal government's stimulus spending. Now U.S. citizens can see exactly how their taxpayer dollars go toward funding video games that test autism responses, or discovering lakes hidden beneath the Antarctic ice sheet.
Server farms are undeniably awesome in that they store huge pools of data, enable such modern phenomena as cloud computing and Web-hosted email, and most importantly, make the Internet as it stands today possible. The downside: data centers get very, very hot. Cooling huge banks of servers doesn't just cost a lot, it eats up a lot of energy, and that generally means fossil fuels.
