MRI detects early effects of chemotherapy on children's hearts Posted: 09 Jun 2013 07:08 PM PDT MRI scans of children who have had chemotherapy can detect early changes in their hearts.

How do you feed nine billion people? Posted: 09 Jun 2013 04:57 PM PDT 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.

3-D map of blood vessels in cerebral cortex holds suprises Posted: 09 Jun 2013 04:57 PM PDT 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.

Teacher collaboration, professional communities improve many elementary school students' math scores Posted: 07 Jun 2013 01:03 PM PDT Many elementary students' math performance improves when their teachers collaborate, work in professional learning communities or do both, yet most students don't spend all of their elementary school years in these settings, a new study shows. The researchers used a sub-sample of 4,490 students, who attended public elementary schools between 1998 and 2003, from the US Department of Education's nationally representative Early Childhood Longitudinal Study.
