In a groundbreaking new study from UC San Francisco, researchers have found that children affected with SPD have quantifiable differences in brain structure, for the first time showing a biological basis for the disease that sets it apart from Benioff Children's Hospital, ranked among the nation's best and one of California's top-ranked centers for neurology and other specialties, according to the 2013-2014 U.S. news & World Report Best Children's Hospitals survey.
A group of five young researchers in this field includes Northwestern scientists from a range of disciplines -- chemistry, biology and engineering -- working with an interdisciplinary approach to solve pressing challenges in global public put Northwestern on the map as a national leader in this growing area of study, joining early pioneers such as Massachusetts Institute of Technology, Harvard University, Stanford University and the University of California at Berkeley.
The traditional studies sought explanations for how the body plans of the three dozen or so major animal groups most likely evolved, but molecular data provide strong evidence about genealogical relationships without yielding explanations. . A key assumption that biologists have relied on widely over the past quarter-century in studying the evolution of protein molecules is "highly questionable," according to an article published in the November issue of BioScience.
(Phys.org) —A George Washington University biologist and a team of researchers have created the first large-scale evolutionary family tree for every snake and lizard around the globe. Biologists map the family tree of all known snake and lizard groups. May 08, 2013 . (Phys.org)— A new study, published online in biology Letters on September 19, has utilized a massive molecular dataset to reconstruct the evolutionary history of lizards and snakes. The results
For decades, the story of spider evolution went like this: As insects became more and more diverse, with some species taking to the skies, spiders evolved new hunting strategies, including the ability to weave orb-shaped webs to The study is described in a July 17 paper published in Current biology. "But the genes that were being used weren't enough to elucidate the evolution of a very diverse group like spiders, so most people dismissed many of those results.
ENENews.com – Energy news Scientists: Fukushima radiation is causing “serious biological effects” — Disaster's widespread impact now being revealed — “Major irreversible shifts” in ecosystems discussed — “High rates of abnormality and mortality”… severe damage to humans next? mon to all of the published studies is the hypothesis that chronic (low-dose) exposure to ionizing radiation results in genetic damage and increased mutation rates [.

Despite being one of the most genetically analysed groups, the origin of European Jews has remained obscure. However, a new study published online today in the journal Genome biology and Evolution by Dr Eran Elhaik,
