An efficacious and cheap alternative Commercial albumin is currently extracted from blood, but the lack of sufficient ...

New RNAi tools enable systematic studies of gene function

...s applied to thousands of genes ?as it has been in fruit flies and nematodes ?it can provide a more complete picture of that process," said David Root, a senior author of the Cell paper and the director of TRC and the RNAi platform at the Broad Institute. "Thanks to this unique public-private effort, we no...

Genome sequencing is for ecologists, too

...because they are important model organisms -- like fruit flies -- or because they are important in disease or agriculture," said Jeffrey Boore, head of the evolutionary genomics program at the Joint Genome Institute. "And the Daphnia genome sequence will illuminate all of this by allowing us to infer the g...

How taste response is hard-wired into the brain

...in. Indeed, in studies with the easily manipulable fruit fly Drosophila, Kristin Scott and colleagues reported in the January 19, 2006, issue of Neuron experiments demonstrating just such a hard-wired circuitry. Their findings, they said, favor a model for taste encoding in the brain that holds that speci...

One reason that pollen becomes limiting to plants in regions of high diversity may be increased competition between the plants -- there are more plant species vying for the services of pollinat...
