Computers to save unique type of American red squirrel

...ch as limiting access to the mountain, restricting hunting and an existing squirrel refuge did not appear to be stemming the population's decline. He said: "It's very important that we preserve the Mount Graham Red Squirrel, which has survived since the last Ice Age. Its decline in recent years is an indicat...

Performing monkeys in Asia carry viruses that could jump species to humans

...arch on viral transmission has focused on bushmeat hunting and consumption, a practice in which local residents hunt wild monkeys for food. HIV, the virus that causes AIDS in humans, is believed to have originated as a primate virus and jumped the species barrier to humans when African bushmeat hunters came ...

Seal rookeries could provide a reliable food source for endangered California condors, study finds

...ich would require legislation or a major change in hunting practices. Third, and this is what we're suggesting, you could train them on another food source that reduces their chances of lead contamination, and that would be the marine mammals." At least one group of condors appears to be heeding that advice...

Suspecting that a defect in antioxidant response exacerbates asthma severity, the team of researchers began looking into ...

Researchers predict infinite genomes

...flip side, scientists may eliminate a core genome, hunting instead for fringe genes that explain a specific strain's unique activity. TIGR researchers say the pan-genome concept also underscores the limits of traditional known genomes. Researchers often refer to a "type" genome to describe a given species. ...
