1. Insects Trained In Quest For Artificial Nose
   Researchers have discovered that when training insects, the process of building associations is not a simple matter of strengthening connections through reinforcement. Understanding how associations are built between stimuli and behavior gives insight into the nature of learning and could inform the...

2. Fat-regenerating 'Stem Cells' Found In Mice
   Researchers have identified stem cells with the capacity to build fat. Although they have yet to show that the cells can renew themselves, transplants of the progenitor cells isolated from the fat tissue of normal mice can restore normal fat tissue in animals that are otherwise lacking it. The findi...

3. Preserved By Ice: Glacial Dams Helped Prevent Erosion Of Tibetan Plateau
   New research suggests that the edge of the Tibetan plateau might have been preserved for thousands of years by ice and glacial debris at the mouth of many tributaries to the Tsangpo River. Those deposits appear to have acted as dams that prevented the rapidly traveling Tsangpo from carving upstream ...

5. Gut Reaction To Arsenic Exposure Simulated
   A simulated gastrointestinal system is helping scientists test contaminated soil for its potential to harm humans. The method is likely to save time and money for people hoping to repurpose land with an industrial past. Most testing for potential arsenic exposure is conducted in recognition of a dir...

6. Babies And Beethoven: Infants Can Tell Happy Songs From Sad
   A new study shows that 5-month-old babies can distinguish an upbeat tune, such as "Ode to Joy" from Beethoven's Ninth Symphony, from a lineup of gloomier compositions. By age 9 months, babies can do the opposite and pick out the sorrowful sound of Beethoven's Seventh Symphony from a pack of happy pi...

7. Brainy Genes, Not Brawn, Key To Success On Mussel Beach
   Scientists have found that mussels in their natural habitat express their genes in cyclic waves, in what appears to be a survival strategy akin to the circadian rhythms that govern sleep. In addition, two sets of genes used to cope with heat stress are identified, in the first real-time molecular sa...

11. Scientists Explore Putting Electric Cars On A Two-way Power Street
    Think of it as the end of cars' slacker days: No more sitting idle for hours in parking lots or garages racking up payments, but instead earning their keep by providing power to the electricity grid. Scientists are exploring plug-in hybrid electric vehicles that not only use grid electricity to meet...
