Potential role of 'love hormone' oxytocin in brain function revealed Posted: 04 Aug 2013 11:45 AM PDT Researchers have deciphered how oxytocin, acting as a neurohormone in the brain, not only reduces background noise, but more importantly, increases the strength of desired signals. These findings may be relevant to autism, which affects one in 88 children in the United States.

Scientists discover potential new way to treat anxiety Posted: 04 Aug 2013 11:45 AM PDT Chemically modified inhibitors of the COX-2 enzyme relieve anxiety behaviors in mice by activating natural "endocannabinoids" without gastrointestinal side effects, scientists report. Endocannabinoids are natural signaling molecules that activate cannabinoid receptors in the brain, the same receptors turned on by the active ingredient in marijuana.

Scientists decipher structure of NatA, an enzyme complex that modifies most human proteins Posted: 04 Aug 2013 11:45 AM PDT Scientists have determined the structure of NatA, an enzyme complex that modifies one end of most human proteins and is made at elevated levels in numerous forms of cancer. Their findings, they believe, will allow them to create an inhibitor -- a potential drug -- that could knock out NatA in order to curb the growth of cancer cells.

Global investigation reveals true scale of ocean warming Posted: 04 Aug 2013 11:44 AM PDT Warming oceans are causing marine species to change breeding times and shift homes with expected substantial consequences for the broader marine landscape, according to a new global study.

Hidden magnetic waves discovered in high-temperature superconductors Posted: 04 Aug 2013 11:44 AM PDT Advanced x-ray technique reveals surprising quantum excitations that persist through materials with or without superconductivity.

Locating the brain's GPS: Human neurons link to navigation in open environments Posted: 04 Aug 2013 11:44 AM PDT Using direct human brain recordings, scientists have identified a new type of cell in the brain that helps people to keep track of their relative location while navigating an unfamiliar environment.

New coating turns ordinary glass into super glass Posted: 04 Aug 2013 05:11 AM PDT A new transparent, bioinspired coating makes ordinary glass tough, self-cleaning and incredibly slippery.

A crystal of a different color: One chemical forms two colors of crystals, sheds insight on agostic bonds important in industrial catalysis Posted: 04 Aug 2013 05:11 AM PDT Chemists have unexpectedly made two differently colored crystals -- one orange, one blue -- from one chemical in the same flask while studying a special kind of molecular connection called an agostic bond. The discovery provides industrial chemical reactions such as those that occur while making plastics and fuels.

Video games boost visual attention but reduce impulse control Posted: 04 Aug 2013 05:11 AM PDT A person playing a first-person shooter video game like Halo or Unreal Tournament must make decisions quickly. That fast-paced decision-making, it turns out, boosts the player's visual skills but comes at a cost, according to new research: reducing the person's ability to inhibit impulsive behavior. This reduction in what is called "proactive executive control" appears to be yet another way that violent video games can increase aggressive behavior.

Nasa's Hubble finds 'smoking gun' after gamma-ray burst Posted: 04 Aug 2013 05:09 AM PDT Probing the location of a recent short-duration gamma-ray burst in near-infrared light, astronomers using the Hubble Space Telescope found the fading fireball produced in the aftermath of the blast. The afterglow reveals for the first time a new kind of stellar blast called a kilonova.
