UT Southwestern researchers receive $15.1 million in federal grants to study biothreats
... or person-to-person contact. It is mild or has no observable symptoms in about 80 percent of people infected, with the remaining 20 percent having a severe multisystem disease. During an epidemic of Lassa fever, up to 50 percent of hospitalized patients with the illness would die. "We are developing drugs to u...Gene expression tied to social behavior in honey bees
...es in gene expression were small, the changes were observable in 40 percent of the genes studied, the scientists report in the Oct. 10 issue of the journal Science. "We have discovered a clear molecular signature in the bee brain that is robustly associated with behavior," said principal researcher Gene E. Robi...Adult alcoholism and attention-deficit hyperactivity disorder are connected
...indicate a distinct phenotype, a way to measure an observable trait or behavior. Adult alcoholics with ADHD had a significantly higher daily and record intake of alcohol per month, an earlier age of onset of alcohol dependence, a higher frequency of thoughts about suicide, a greater number of court proceedings...Map of genes in plant root yields new tool for exploring tissue development
...gues is that the Arabidopsis root offers an easily observable and accessible model of the development of complex tissue from a single cell. Unlike the impossibly intricate convolutions and migrations of developing animal tissues, each new cell in the Arabidopsis root arises conveniently from its neighbor. Also,...Running afowl: NU researchers first to measure energy used by leg muscles
...most research on running has been based externally observable phenomena. By being able to estimate the energy use by the individual muscles, we were able to account to for energy consumption during swing-phase. Our work maintains Taylor's emphasis on using energetics to understand terrestrial locomotion, but ou...Rutgers researcher offers a new perspective on human evolution
...nsible for the formation of arms and legs with the observable diversity in limb structure among humans and other primates. In the growing field of evolution and development, known as EvoDevo, the view is that significant developmental differences are due to changes in gene regulation. "Once we have the struct...Complex cells likely arose from combination of bacterial and extreme-microbe genomes
...creatures, a process that was once based on easily observable traits. Microbes, plants or animals were said to be related if they shared certain, mostly physical, characteristics. DNA technology now allows much closer scrutiny of hereditary molecules, which provides a more accurate and detailed picture of the ...
