Sleep-Wake Controls Identified: Implications For Coma Patients And Tho
How do we wake up? How do we shift from restful sleep to dreaming? Researchers have discovered a new brain mechanism that just might explain how we do that. This new mechanism also may help us understand how certain anesthetics put us to sleep and how certain stimulants wake us up. New Theory Explains Schizophrenia As Abnormal Courtship; Disorder Surv
Scientifically, schizophrenia should not exist. It crushes sexual relationships and reproductive success. Because the illness is genetic, evolution should have eliminated it long ago. Instead, it continues to afflict one in 100 people, too many to be due to just a few kinds of bad genes. A new theory proposes that schizophrenia is an inevitable consequence of courtship behaviors that have evolved expressly to reveal bad genes. Chipmunks And Shrews, Not Just Mice, Harbor Lyme Disease
Biologist in the tick-infested woods of the Hudson Valley are challenging the widely held belief that mice are the main animal reservoir for Lyme disease in the US. Chipmunks and two shrew species, not just mice, are the four species that account for major outbreaks. Tracking Audis With RFID
Audi will use RFID tags through production and delivery of its TT sports car for "quality-assurance." But how are the embedded tags used over a car's lifetime? Plus: BMW fields a remote-control convertible top. In Autopia. Largest Study Of Unrelated Bone Marrow Transplantation For Leukemia Se
Together with 16 other institutions in the United States, University of Minnesota researchers led the largest study to date in patients with leukemia and related disorders undergoing bone marrow transplantation from unrelated donors. The study was designed to determine whether one of two general approaches to prevent graft-versus-host-disease (GVHD), a potentially lethal complication, might result in improved survival. Antidepressants, Exercise, Age, Even Food Intake, Affect Generation Of
Recent research shows that the production of new brain cells may be crucial for antidepressants to be effective and that the medication's effectiveness is strongly influenced by age. What's more, meal frequency, type of food, and physical exercise affect the brain's ability to manufacture these new cells. For the first time in nonhuman primate models, scientists have documented the cause-and-effect relationship between antidepressant drugs and neurogenesis. Roald Dahl's 'Fantastic Mr. Fox' Melds Classic Stop-Motion, Cutting-Ed
On the surface, stop-motion animation is a very low-tech process, but to create the world of Fantastic Mr. Fox, based on the beloved children's book by Roald Dahl, it required an architecture of cutting-edge technology capable of handling the 5,229 shots with 621,450 frames totaling 120 GB of data.
 One Small Step For Neurons, One Giant Leap For Nerve Cell Repair
The repair of damaged nerve cells is a major problem in medicine today. A new study is a significant advance towards a solution for neuronal repair. Scientists have created nerve cell connections in vitro using artificial substances, a major advance towards nerve cell repair. Sexual Behavior and Selected Health Measures: Men and Women 15-44 Year
This 2005 report "is intended to provide reliable national estimates of some basic statistics on certain types of sexual behavior, sexual orientation, and sexual attraction for men and women. ...
