Why do birds migrate?
...aits across the many species of Tyranni by using a computer
analysis called phylogenetic independent contrasts. The technique allowed the scientists to sort out whether a bird was migratory because that's what species on their side of the family tree always did or whether the bird's travel habits had some e...
Individuals and populations differ in gene activity levels, not just genes
...and gene expression is like the difference between computer
hardware, which are the genes themselves, and computer
software, which tells the computer
what to do on the hardware," explained Storey. "We looked at what...

...t small levels," Codd said. "We are able to create computer
simulations based on physics about how fluids behave, but with MRM we can see inside objects to see if those simulations are correct and if that's how things really work." About the size of a small chest freezer tipped on end, the MRM device allows...

Virtual duck bills demonstrate species coexistence
...To test his idea, Gurd created virtual bills using computer
software typically used by engineers to design complex machinery. "The software allowed me to create exact, three-dimensional replicas of duck bills complete with articulating joints" said Gurd. "The replicas allowed me to determine the particle size...

Weizmann Institute scientists discover genes that can slow cell division and may fight cancer
... collaboration between physicists, mathematicians, computer
scientists, and biologists the sort of multidisciplinary research for which the Weizmann Institute has gained a global reputation yielded some startling results. They found that following the receipt of the growth factor signal, cell activity takes...
Fruit flies may pave way to new treatments for age-related heart disease

prediction of differential targeting by unedited and edited microRNAs of different sets of genes is likely to be correct," Nishikura says. "And in at least the case of the one gene we investigated, this differential has physiological consequences see...
