An international team of scientists has developed crop models to better forecast food production to feed a growing population -- projected to reach 9 billion by mid-century -- in the face of climate change.

Duck genome provides new insight into fighting bird flu

Posted: 09 Jun 2013 04:57 PM PDT

The duck genome consortium has completed the genome sequencing and analysis of the duck (Anas platyrhynchos), one principal natural host of influenza A viruses, which caused a new epidemic in China since this February. This work reveals some noteworthy conclusions and provides an invaluable resource for unraveling the interactive mechanisms between the host and influenza viruses.

Blood vessels within a sensory area of the mammalian brain loop and connect in unexpected ways, a new map has revealed.

Carbon nanotubes for molecular magnetic resonances

Posted: 09 Jun 2013 04:57 PM PDT

Researchers have developed a new technique for measuring very weak forces on a molecular scale. Thanks to the use of carbon nanotubes, they have achieved the highest level of sensitivity to date. These results open the door for magnetic resonance imaging of individual molecules.

Scientists map process by which brain cells form long-term memories

Posted: 09 Jun 2013 04:57 PM PDT

Scientists have deciphered how a protein called Arc regulates the activity of neurons -- providing much-needed clues into the brain's ability to form long-lasting memories. These findings also offer newfound understanding as to what goes on at the molecular level when this process becomes disrupted.

Interferon-beta aids balance and movement in mice with spinocerebellar ataxia 7; first in vivo study of the treatment for this condition shows significant physical improvement

Posted: 09 Jun 2013 04:56 PM PDT

The first in vivo trial of the use of interferon-beta in a mouse model of the group of fatal diseases known as spinocerebellar ataxia has shown that its use can significantly improve their physical condition and control symptoms.  Researchers believe that their results show that a clinical trial in humans is merited.

Scientists identify potential drug target for treatment-resistant anemias

Posted: 09 Jun 2013 04:56 PM PDT

Researchers have identified a key target protein of glucocorticoids, the drugs that are used to increase red blood cell production in patients with certain types of anemia, including those resulting from trauma, sepsis, malaria, kidney dialysis, and chemotherapy. The discovery could spur development of drugs capable of increasing this protein's production and thus increased numbers of red blood cells without causing the severe side effects associated with glucocorticoids.
