• 20:41 More environmental rules needed for shale gas, says geophysicist

  Read the story at ScienceDaily
  In his State of the Union address, President Barack Obama praised the potential of the country's tremendous supply of natural gas buried in shale. But the "Halliburton exclusion" passed by Congress says gas companies don't have to disclose the chemicals used in fracturing fluids. That was a real mistake because it makes the public needlessly paranoid, says a geophysicist.

• 20:39 Exercise triggers stem cells in muscle

  Read the story at ScienceDaily
  Researchers have determined that an adult stem cell present in muscle is responsive to exercise, a discovery that may provide a link between exercise and muscle health. The findings could lead to new therapeutic techniques using these cells to rehabilitate injured muscle and prevent or restore muscle loss with age.

• 20:39 It's not solitaire: Brain activity differs when one plays against others

  Read the story at ScienceDaily
  Researchers have found a way to study how our brains assess the behavior -- and likely future actions -- of others during competitive social interactions. Their study is the first to use a computational approach to tease out differing patterns of brain activity during these interactions, the researchers report.

• 20:39 PET techniques provide more accurate diagnosis, prognosis in challenging breast cancer cases

  Read the story at ScienceDaily
  Researchers are revealing how molecular imaging can be used to solve mysteries about difficult cases of breast cancer. One recent article focuses on an imaging agent that targets estrogen receptors in estrogen receptor–positive breast cancer patients with formerly inconclusive assessments, and the second highlights a different imaging agent's ability to help predict the prognosis for patients undergoing chemotherapy for a very aggressive type of breast cancer.

• 20:39 Researchers examine consequences of non-intervention for infectious disease in African great apes

  Read the story at ScienceDaily
  Infectious disease has joined poaching and habitat loss as a major threat to the survival of African great apes as they have become restricted to ever-smaller populations. Despite the work of dedicated conservationists, efforts to save our closest living relatives from ecological extinction are largely failing, and new scientific approaches are necessary to analyze major threats and find innovative solutions.

• 18:27 Key finding in stem cell self-renewal

  Read the story at ScienceDaily
  Scientists have proposed a mechanism for the control of whether embryonic stem cells continue to proliferate and stay stem cells, or differentiate into adult cells like brain, liver or skin. The work has implications in two areas. In cancer treatment, it is desirable to inhibit cell proliferation.

• 18:26 New species of bamboo-feeding plant lice found in Costa Rica

  Read the story at ScienceDaily
  Several periods of field work during 2008 have led to the discovery of a new species of bamboo-feeding plant lice in Costa Rica's high-altitude region Cerro de la Muerte. The discovery was made thanks to molecular data analysis of mitochondrial DNA. The collected records have also increased the overall knowledge of plant lice (one of the most dangerous agricultural pests worldwide) from the region with more that 20 percent.

• 16:29 East views the world differently to West

  Read the story at ScienceDaily
  Cultural differences between the West and East are well documented, but a study shows that concrete differences also exist in how British and Chinese people recognize people and the world around them. Easterners really do look at the world differently to Westerners, according to new research.

• 16:29 Low levels of lipid antibodies increase complications following heart attack

  Read the story at ScienceDaily
  Coronary patients with low levels of an immune system antibody called anti-PC, which neutralizes parts of the "bad" cholesterol, run a greater risk of suffering complications following an acute cardiac episode and thus of premature death.

• 16:29 Playing RFID tag with sheets of paper

  Read the story at ScienceDaily
  Researchers in France have developed a way to deposit a thin aluminum RFID tag onto paper that not only reduces the amount of metal needed for the tag, and so the cost, but could open up RFID tagging to many more systems, even allowing a single printed sheet or flyer to be tagged.

• 22:38 Key to immune cell's 'internal guidance' system discovered

  Read the story at ScienceDaily
  Researchers have discovered the molecular pathway that enables receptors inside immune cells to find, and flag, fragments of pathogens trying to invade a host. The discovery of the role played by the molecule CD74 could help immunologists investigate treatments that offer better immune responses against cancers, viruses and bacteria, and lead to more efficient vaccines.
