| New neurons generated in the hippocampus of adult humans Posted: 07 Jun 2013 07:16 AM PDT The hippocampus is a region in the brain crucial for the ability to learn and remember. In a new study, published in the journal Cell, researchers at Karolinska Institutet show that a large number of new neurons are generated in the hippocampus of adult humans - which has long been an issue of debate. To reach this conclusion, the researchers measured the amount of carbon-14 found in humans as a result of nuclear testing during the 50s and 60s. |
| Herpes Virus Exploits Immune Response to Bolster Infection Posted: 06 Jun 2013 12:23 PM PDT Researchers at the University of California, San Diego School of Medicine and colleagues report that the herpes simplex virus type-1 (HSV-1), which affects an estimated 50 to 80 percent of all American adults, exploits an immune system receptor to boost its infectivity and ability to cause disease. |
| New technique for deep brain stimulation surgery proves accurate and safe Posted: 06 Jun 2013 12:14 PM PDT Surgery has been used for Parkinson’s disease and familial tremors, and also shows promise for other disorders |
| 'Temporal cloaking' could bring more secure optical communications Posted: 06 Jun 2013 12:06 PM PDT Researchers have demonstrated a method for "temporal cloaking" of optical communications, representing a potential tool to thwart would-be eavesdroppers and improve security for telecommunications. |
| Researchers Discover How Brain Circuits Can Become Miswired During Development Posted: 06 Jun 2013 11:53 AM PDT Researchers at Weill Cornell Medical College have uncovered a mechanism that guides the exquisite wiring of neural circuits in a developing brain — gaining unprecedented insight into the faulty circuits that may lead to brain disorders ranging from autism to mental retardation. |
| Nutrition During First 1,000 Days of Life Crucial for Childhood and Economic Development Posted: 06 Jun 2013 11:05 AM PDT A new Lancet series on maternal and childhood nutrition finds that over 3 million children die every year of malnutrition—accounting for nearly half of all child deaths under 5. Along with state-of-the-art global estimates on the long-term burden of malnutrition, the series presents a new framework for prevention and treatment that considers underlying factors, such as food security, social conditions, resources, and governance. |
| Breastfeeding benefits babies’ brains Posted: 06 Jun 2013 11:00 AM PDT A study using brain images from “quiet” MRI machines adds to the growing body of evidence that breastfeeding improves brain development in infants. Breastfeeding alone produced better brain development than a combination of breastfeeding and formula, which produced better development than formula alone. |
