The distinction is significant, said the researchers, ...

Gorilla susceptibility to Ebola virus: the cost of sociality

...-called "reservoir" species (unknown, but possibly fruit bats), with ape-to-ape transmission playing only a minor role due to an insufficient rate of encounters between groups. In the new work, the researchers studied the spread of Ebola virus in a gorilla population of Odzala-Kokoua National Park, Repub...

Parallel evolution: Proteins do it, too

...keys in that they primarily eat leaves rather than fruit or insects, and leaves are very difficult to digest," Zhang said. The monkeys manage with a digestive system similar to a cow's. Bacteria in the gut ferment the leaves and take up nutrients that are released in the process. The monkeys, in turn, dige...

Study identifies substances in grapefruit juice that interact dangerously with some drugs

... Grapefruit juice, but not other commonly consumed fruit juices, inhibits this enzyme, allowing more of these drugs to enter the body. It was originally assumed that the ingredients responsible for drug interactions were the flavonoids that give grapefruit juice its bitter taste. The new study shows th...

Gardenia fruit compound starting point for diabetes therapy

A Gardenia fruit extract traditionally used in Chinese medicine to treat the symptoms of type 2 diabetes does indeed contain a chemical that reverses some of the pancreatic dysfunctions that underlie the disease, researchers report in the June 7, 2006, Cell Metabolis...

Serotonin, acting in a specific brain region, promotes sleep in fruit flies

...ar in the June 6th issue of Current Biology. The fruit fly, Drosophila melanogaster, is now established as a useful model for sleep research. The simple nervous system of the fly enables researchers to ask basic questions about sleep regulation and function that have been difficult to address in the more...

"In our study, we showed spectrin doesn't have to bind to ankyrin to do its job," said Dubreuil. "This hints at a complexity we never had any idea about i...

Scientists identify 36 genes, 100 neuropeptides in honey bee brains

...led genes discovered in other species, such as the fruit fly (Drosophila melanogaster). And, because genes that produce neuropeptides often have repeating sequences, some of the genes were found by a computer algorithm that scanned the honey bee genome for such telltale sequences. "We found 36 genes, fro...
