| Study Shows a Solitary Mutation Can Destroy Critical ‘Window’ of Early Brain Development Posted: 21 Jun 2013 06:44 AM PDT Scientists from the Florida campus of The Scripps Research Institute (TSRI) have shown in animal models that brain damage caused by the loss of a single copy of a gene during very early childhood development can cause a lifetime of behavioral and intellectual problems. |
| Pistil leads pollen in life-and-death dance Posted: 20 Jun 2013 01:00 PM PDT Pollination, essential to much of life on earth, requires the explosive death of the male pollen tube in the female ovule. In new research, Brown University scientists describe the genetic and regulatory factors that compel the male’s role in the process. Finding a way to tweak that performance could expand crop cross-breeding possibilities. |
| How did a third radiation belt appear in the Earth's upper atmosphere? Posted: 20 Jun 2013 12:51 PM PDT Since the discovery of the Van Allen radiation belts in in the Earth's upper atmosphere in 1958, space scientists have believed that these belts consisted of two doughnut-shaped rings of highly charged particles — an inner ring of high-energy electrons and energetic positive ions, and an outer ring of high-energy electrons. |
| Keeping cabbage in light-dark cycles? Altering rhythm of harvested vegetables to make anti-oxidants Posted: 20 Jun 2013 09:05 AM PDT A new study shows that internal rhythm of harvested vegetables such as cabbage can be altered by changing light-dark cycles. In this new report, the scientists showed how manipulation of circadian rhythms caused cabbage to produce more phytochemicals, including antioxidants. They found that keeping the internal clock ticking is advantageous with respect to insect resistance and could also yield health benefits. The findings suggest that storing fruits and vegetables in dark trucks, boxes and refrigerators may reduce their ability to keep daily rhythms. |
| TrkB - a new drug target to prevent epilepsy Posted: 20 Jun 2013 09:05 AM PDT Duke neuroscientists report that the brain receptor TrkB may be a potential drug target in the prevention of epilepsy. In a mouse model of epilepsy, they showed that treatment with 1NMPP1, an inhibitor of TrkB, prevented the onset of epilepsy. |
| Scientists Design a Potential Drug Compound that Attacks Parkinson’s Disease on Two Fronts Posted: 20 Jun 2013 07:21 AM PDT Scientists from the Florida campus of The Scripps Research Institute (TSRI) have found a compound that could counter Parkinson’s disease in two ways at once. In a new study published recently online ahead of print by the journal ACS Chemical Biology, the scientists describe a “dual inhibitor”—two compounds in a single molecule—that attacks a pair of proteins closely associated with development of Parkinson’s disease. |
| Nearly 7 in 10 Americans Are On Prescription Drugs, Germ fighters, Antidepressants, Opioids Top List Posted: 20 Jun 2013 07:13 AM PDT Nearly 70 percent of Americans are on at least one prescription drug, and more than half take two, Mayo Clinic researchers say. Antibiotics, antidepressants and painkilling opioids are most commonly prescribed, their study found. Twenty percent of patients are on five or more prescription medications, according to the findings, published online in the journal Mayo Clinic Proceedings. |
