• Neuroscientists identify how the brain works to select what we (want to) see February 22, 2012
  If you are looking for a particular object -- say a yellow pencil -- on a cluttered desk, how does your brain work to visually locate it? For the first time, neuroscientists have identified how different neural regions communicate to determine what to visually pay attention to and what to ignore. This finding is a major discovery for visual cognition and wil […]
• Cocaine and the teen brain: New insights into addiction February 22, 2012
  When first exposed to cocaine, the adolescent brain launches a strong defensive reaction designed to minimize the drug's effects, scientists have found. Now two new studies identify key genes that regulate this response and show that interfering with this reaction dramatically increases a mouse's sensitivity to cocaine. […]
• Superbugs from space offer new source of power February 22, 2012
  Scientists have created a "designer slime" that can double the electrical output of existing microbial fuel cells. Bacillus stratosphericus -- a microbe commonly found in high concentrations in the stratosphere orbiting Earth with the satellites -- is a key component of a new 'super' biofilm. […]
• Caught in the act: Scientists discover microbes speciating February 22, 2012
  Not that long ago in a hot spring in Kamchatka, Russia, two groups of genetically indistinguishable microbes decided to part ways. They began evolving into different species – despite the fact that they still encountered one another in their acidic, boiling habitat and even exchanged some genes from time to time, researchers report. This is the first example […]
• Stronger intestinal barrier may prevent cancer in the rest of the body, new study suggests February 22, 2012
  Researchers have found that silencing a hormone receptor weakens the intestinal barrier, making the body more susceptible to cancer. […]
