Biomedical uses for hydrogels explored Posted: 05 Jul 2013 06:22 PM PDT Scientists are researching hydrogel, the gelatinous substance that, because of its toughness and plasticity, has several biomedical applications, including cartilage repair, implants for minimally invasive surgery and drug delivery.

How the brain creates the 'buzz' that helps ideas spread Posted: 05 Jul 2013 06:22 PM PDT How do ideas spread? What messages will go viral on social media, and can that be predicted? Psychologists report for the first time which brain regions are associated with the successful spread of ideas, often called "buzz." The research has a broad range of implications, and could lead to more effective public health campaigns.

Researcher sheds light on M.O. of unusual RNA molecules Posted: 05 Jul 2013 06:22 PM PDT Researchers have figured out how some RNA molecules take advantage of their position within the three-dimensional mishmash of genomic material to home in on targets.

Why some women don't have enough breastmilk for baby: Important role of insulin in making breast milk identified Posted: 05 Jul 2013 06:22 PM PDT Why do so many mothers have difficulty making enough milk to breastfeed? A new study adds to previous research implicating insulin's role in lactation success.

Legal performance enhancer discovered in the nutrient betaine Posted: 05 Jul 2013 06:21 PM PDT Betaine —- a nutrient found in shellfish and beets —- boosts athletic performance by nearly six percent when added to a sports drink.

Proteins key in stem cell production identified Posted: 05 Jul 2013 08:36 AM PDT Researchers may be one step closer to a 'recipe' for large-scale production of stem cells for use in research and therapy.

Unique epigenomic code identified during human brain development Posted: 05 Jul 2013 07:20 AM PDT Experience of parents with their children and teachers with their students demonstrate how kids change their behaviors and knowledge from infancy to adolescence. Until now, little was known of the causes that could lead to these changes. New findings uncovers dynamic changes in the epigenome that occur during brain circuitry formation.

Exercise rescues mutated neural stem cells Posted: 05 Jul 2013 07:17 AM PDT The genetic mutation leading to the developmental disorder "CHARGE syndrome" blocks the maturation of neural stem cells. This finding explains why CHARGE patients suffer from mental retardation and learning disabilities. Strikingly, exercise by running can completely rescue the CHARGE phenotype.

Technological breakthrough paves the way for better drugs Posted: 05 Jul 2013 07:15 AM PDT Researchers have developed the first method for directly measuring the extent to which drugs reach their targets in the cell. The method could make a significant contribution to the development of new, improved drug substances.
