After flu exposure, mild exercise protects mature mice from dying
...predicting mortality. However, severe lethargy was apparent one to two days prior to death. And while there was a "marked, age-dependent effect on mortality, there was no effect at all on morbidity, which was somewhat surprising," Woods said. The Illinois researchers plan on doing followup studies with anima...T cell's memory may offer long-term immunity to leishmaniasis
... Scott and his colleagues wondered if, despite the apparent loss of immunity when the parasites disappeared, there were any T cells that still retained memory of Leishmania. Recent studies have shown that memory T cells may be of more than one type. One type, which is less activated and found in the lymph n...FSU scientist links iron imbalance to Parkinson's disease

The need for the university database became apparent in the late 1990s after Brown and David Botstein, PhD, former chair of the genetics department, had put together a database for their own microarray results.

"This study suggests that social interactions greatly affect the way a song is learned," he adds.
