Unravelling new complexity in the genome

...es tailored designed microarrays or gene chips and computer algorithms, allows the simultaneous measurement of thousands of alternative splicing events in cells and tissues. Until recently researchers studied splicing regulation on a gene by gene basis. Now we can obtain a picture of what is happening on a gl...

OHSU turns mouse into factory for human liver cells

... be predicted with any current technology, such as computer models. You actually have to see what human liver cells do with any given drug." And human liver cells must be used instead of cells from laboratory animals because liver enzymes that break down these compounds are species specific. "Animal liver c...

Evolution is driven by gene regulation

...egions, making them harder to identify by standard computer comparisons. While many molecules that bind DNA regulatory regions have been identified as transcription factors mediating gene regulation, we have now shown that we can functionally map these interactions and identify the specific targeted promote...

Satellite tracking reveals threats to Borneo pygmy elephants

... periods. The collars sent GPS locations to a WWF computer via satellite as often as once a day. This was the first long-term study done of Borneo pygmy elephants. Its amazing that we still know so little about one of the biggest land mammals on Earth, said Matthew Lewis, program officer for WWFs Species C...

Using computer simulations, Stone demonstrates in a study, publishing in the open access journal PLoS Computational Biology, that the ability to learn in network models has two surprising consequences. First, learning accelerates the rate at which a skill becomes i...

Surprising new species of light-harvesting bacterium discovered in Yellowstone

...cies. Says Bryant, "Finding two new genes with a computer is not enough to justify naming a new organism. You need to prove those genes come from the same genome." Because the two genes were close together in the genome, the team was successful in isolating a single fragment containing both. "We were luc...

Yet these must pinpoint and then bind to specific counterparts while swimming in the cells thick, erratic molecular ste...

Carnegie Mellon scientists find key HIV protein makes cell membranes bend more easily
