• 01:25 New approach to graft-versus-host treatment results in improvement for some patients

  Read the story at PhysOrg
  In a study that seems to pivot on a paradox, scientists at Dana-Farber Cancer Institute have used an immune system stimulant as an immune system suppressor to treat a common, often debilitating side effect of donor stem cell transplantation in cancer patients. The effect, in some cases, was profound.

• 01:25 Nokia showcases indoor 3-D mapping phone solution (w/ video)

  Read the story at PhysOrg
  (PhysOrg.com) -- Nokia is showing off a prototype that location enthusiasts consider the next step in indoor mapping. Nokia has built a Location Extension Protocol on top of the Bluetooth 4.0 specification, which enables a phone user to see what Nokia says are highly accurate 3-D maps of indoor environments. While that kind of function may seem pointless when moving around in a small apartment, it is far more important for what Nokia has in mind.

• 01:25 Super athletic mice are fit because their muscles burn more sugar

  Read the story at PhysOrg
  Muscle performance and fitness are partly determined by how well your muscle cells use sugar as a fuel source. In turn, exercising improves the muscle's ability to take up sugars from the bloodstream and burn them for energy. On the flip side, conditions that reduce physical activity -- such as obesity or chronic disease -- reduce the muscle's capacity to burn sugar. A new study by researchers at Sanford-Burnham Medical Research Institute (Sanford-Burnham) unravels a mechanism that re-programs metabolic genes in muscles in a way that increases their capacity to use sugar. When activated in mice, this metabolic re-programming dramatically improves exercise performance.

• 01:25 Texas drought visible in new national groundwater maps

  Read the story at PhysOrg
  (PhysOrg.com) -- The record-breaking drought in Texas that has fueled wildfires, decimated crops and forced cattle sales has also reduced levels of groundwater in much of the state to the lowest levels seen in more than 60 years, according to new national maps produced by NASA and distributed by the National Drought Mitigation Center at the University of Nebraska-Lincoln.

• 01:25 Using radiation to sterilize insect pests may protect California fruits and vegetables

  Read the story at PhysOrg
  A new study published in the Journal of Economic Entomology shows that radiation can be used to effectively sterilize the light brown apple moth (LBAM), an insect pest found in Australia, New Zealand, California, Hawaii, Sweden, and the British Isles. The light brown apple moth, Epiphyas postvittana (Walker), feeds on apples, pears, stonefruits, citrus, grapes, berries and many other plants. A native of Australia, it has been found in California since 2007. The California Department of Food and Agriculture has spent more than $70 million in CDFA and USDA funds to eradicate the LBAM, and estimates that failure to eradicate it could cost California growers over $133 million per year.

• 00:42 U.N. Report Indicates 2011 to Be One of the Hottest Years on Record (ContributorNetwork)

  Read the story at Yahoo!
  ContributorNetwork - According to National Geographic, a United Nations report indicates 2011 is looking to be one of the 10 hottest years on record. The conclusion is especially problematic since this year is part of the La Nina period, a climate pattern marked relatively cooler global conditions. In addition, this year has had numerous extreme weather events, which are often a symptom of global warming and increasing average global temperatures.

• 00:00 How to Keep Commercial Spaceflight Safe: Q&A With FAA's George Nield (SPACE.com)

  Read the story at Yahoo!
  SPACE.com - The commercial space industry in the United States is in its adolescence, growing by leaps and bounds while the federal government sometimes looks on as a watchful and worried parent. But one government agency — the Federal Aviation Administration (FAA), whose job it is to make sure the industry maintains safety standards and doesn't harm anyone on the ground — has decided in some ways to be a cheerleader for its teenage charge.
