Functioning synapse created using carbon nanotubes: Devices might be used in brain prostheses or synthetic brains (April 22, 2011) -- Engineering researchers have made a significant breakthrough in the use of nanotechnologies for the construction of a synthetic brain. They have built a carbon nanotube synapse circuit whose behavior in tests reproduces the function of a neuron, the building block of the brain. ... > full story
Anti-depressants boost brain cells after injury in early studies (April 22, 2011) -- When neurosurgeons noticed that patients with brain injuries who had been prescribed anti-depressants were doing better in unexpected ways than their counterparts who were not taking such medications, scientists took a closer look. Early results in mice indicate that anti-depressants may help spur the creation and survival of new brain cells after brain injury. ... > full story
Worm studies shed light on human cancers (April 22, 2011) -- Research in the worm is shedding light on a protein associated with a number of different human cancers, and may point to a highly targeted way to treat them. ... > full story
Parasite strategy offers insight to help tackle sleeping sickness (April 22, 2011) -- Fresh insight into the survival strategy of the parasite that causes sleeping sickness could help inform new treatments for the disease. ... > full story
Quality of parent-toddler relationship could affect risk for childhood obesity (April 22, 2011) -- Toddlers who do not have a secure emotional relationship with their parents, and particularly their mothers, could be at increased risk for obesity by age 4 and a half, according to new research. The study suggests that children at age 24 months who show insecure attachment patterns have at least 30 percent higher odds for obesity by age 4 and a half. ... > full story
Toward new medications for chronic brain diseases (April 22, 2011) -- A needle-in-the-haystack search through nearly 390,000 chemical compounds had led scientists to a substance that can sneak through the protective barrier surrounding the brain with effects promising for new drugs for Parkinson's and Huntington's disease. The substance blocks the formation of cholesterol in the brain. ... > full story
Athletes at risk: New, inexpensive test for 'sudden death syndrome' (April 22, 2011) -- A cardiologist has developed a new, inexpensive test for "sudden death syndrome" that's already being used by doctors in America -- and it can be done at the patient's bedside. ... > full story
Antidepressants may not improve all symptoms of depression, researchers find (April 22, 2011) -- Even people who show a clear treatment response with antidepressant medications continue to experience symptoms like insomnia, sadness and decreased concentration, researchers have found after analyzing data from the largest study on the treatment of depression. ... > full story
Critical role of placenta in brain development demonstrated (April 22, 2011) -- New research shows for the first time that the human placenta plays an active role in synthesizing serotonin, paving the way to new treatment strategies that could mitigate health impacts such as cardiovascular disease and mental illness. ... > full story
Cancer cell proliferation: A new ending to an old 'tail' (April 22, 2011) -- In stark contrast to normal cells, which only divide a finite number of times before they enter into a permanent state of growth arrest or simply die, cancer cells never cease to proliferate. Now, scientists have uncovered an important clue to one of the mechanisms underlying cancer cell immortality. ... > full story
Subset of self-destructive immune cells may selectively drive diabetes (April 22, 2011) -- New research identifies a distinctive population of immune cells that may play a key role in the pathogenesis of diabetes. The research sheds new light on the pathogenesis of diabetes and may lead to the development of new more selective therapeutic strategies for diabetes and other autoimmune diseases of the accessory organs of the digestive system. ... > full story
Study pinpoints common critical errors in teen crashes (April 22, 2011) -- A recent study hones in on the most common errors teen drivers make that lead to a serious crash. Teen drivers are involved in fatal crashes at four times the rate of adults. ... > full story
