Ernst Mayr's theory illustrated in genetic epidemiology studies
The late, famed evolutionary biologist Ernst Mayr's theory of genetic revolution , introduced in 1954, remains controversial to this day and has many detractors. Mayr believed that genes interacted with one another, and that this genetic interaction in turn led to an interaction of natural selection with genetic drift that could cause genetic revolution ?new directions of evolutionary ch...Mice studies illustrate potential of chimp/human antibodies to protect against smallpox
Results from a new study indicate that hybrid laboratory antibodies derived from chimpanzees and humans may provide a potentially safe and effective way to treat the serious complications that can occur following smallpox vaccination--and possibly may even protect against the deadly disease itself. The study, led by researchers with the National Institute of Allergy and Infectious Diseases (NIAID...Common algae helps illustrate mammalian brain electrical circuitry
Mice whose brain cells respond to a flash of light are providing insight into the complexities of the sense of smell and may ultimately yield a better understanding of how the human brain works. Investigators at Duke University Medical Center and the Howard Hughes Medical Institute have engineered a strain of mice whose olfactory brain cells "fire" when exposed to light. This was accomplis...
