Maternal behavior itself can trigger the development of new neurons in the maternal brain independent of whether the female was pregnant or has nursed, according to a study released by researchers at Tufts University's Cummings School of Veterinary Medicine. These findings performed in adult, virgin rats were published in Brain Research Bulletin. http://www.physorg.com/news180272844.html Medicine & Health Thu, 17 Dec 2009 11:49:01 EST news180272844 A team led by scientists at The Scripps Research Institute have discovered a direct link between insulin -a hormone long associated with metabolism and metabolic disorders such as diabetes -and core body temperature. While much research has been conducted on insulin since its discovery in the 1920s, this is the first time the hormone has been connected to the fundamental process of temperature regulation. http://www.physorg.com/news177861868.html Medicine & Health Thu, 19 Nov 2009 14:20:01 EST news177861868 A series of studies carried out at the University of Haifa have found that rodent, reptile and ant lion species behave differently on either side of the Israel-Jordan border. "The border line, which is only a demarcation on the map, cannot contain these species, but the line does restrict humans and their diverse impact on nature," says Dr. Uri Shanas. http://www.physorg.com/news177847153.html Biology Thu, 19 Nov 2009 10:10:03 EST news177847153 Tom Parker has made an unusual find. In California forests and shrubland that burned in 2008, he has spotted Manzanita seedlings sprouting in tight clusters, suggesting that the young shrubs emerged from underground stashes of seeds.

Daidzin is an anti-drinking substance in kudzu. A synthetic form of daidzin, called CVT-10216, can successfully reduce drinking and prevent relapse in preclinical rodent models. http://www.physorg.com/news169226337.html Medicine & Health Tue, 11 Aug 2009 17:10:02 EST news169226337 Edith Hessel and colleagues, at Dynavax Technologies Corporation, Berkeley, have identified the reason that humans and rodents respond differently to a molecule that is being developed to treat allergic diseases. http://www.physorg.com/news169147890.html Medicine & Health Mon, 10 Aug 2009 19:00:05 EST news169147890 You probably hadn't noticed -- but the head shape and overall size of rodents has been changing over the past century. A University of Illinois at Chicago ecologist has tied these changes to human population density and climate change. http://www.physorg.com/news168241528.html Biology Fri, 31 Jul 2009 06:46:16 EST news168241528 Inhibiting an enzyme in the brains of newborns suffering from oxygen and blood flow deprivation stops a type of brain damage that is a leading cause of cerebral palsy, mental retardation and death, according to researchers at Cincinnati Children's Hospital Medical Center. http://www.physorg.com/news168088136.html Medicine & Health Wed, 29 Jul 2009 12:20:01 EST news168088136 An international team of scientists has discovered an extinct rodent species, based on fossil tooth remains found in Alborache, Valencia.
