Don't stand so close to me: A new view on how species coexist
...Holloway, University of London, added: "The bottom line
of this work is that patterns of diversity are shaped both by ecology and by evolution." One way of capturing the essence of the new work, he added, is expressed in the concept of the 'Darwinian demon' - a hypothetical species that develops rapidly, ...

up at a surface and turn around to point in the opposite direction if the charge on the surface is changed. She has also looked at water at 'oily' surfaces, which is an important step toward understanding the folding of proteins." Earlier in h...

the inner ear and convert mechanical sound vibrations into electrical impulses are known as hair cells named for the tuft of 30-300 cilia, or microscopic hairs, on each cell's surface. Thin filaments called tip links connect the channels in adjacent...

is, the FGF system is less active in depressed individuals and presumably, correcting that would be part of how you can make them better," says Akil, who is co-director of the U-M Mental Health Research Institute. "This finding gives us a new target ...
First-ever Texan/German symposium opens doors

with creating a future joint research program with the MPI-P that would involve new research directions in polymer materials, future grant submissions and perhaps a joint doctoral program," Advincula said. "Knoll's group is very strong in macromolec...

of research into its implication in changes on the state of cellular differentiation induced by dietary lipids in breast cancer tumours and the degree of malignity of the cancer. In general, the research carried out by the Grup Multidisciplinari ...

Calorie restriction leads to some brain benefits but not others in mice

is that you don't get uniformly positive results from calorie restriction. I don't think anyone has really stressed this point before, particularly with regard to the lack of effects on cognition." In addition to validating these findings in larger g...

measurements then monitor the site. But another three to four inch rainfall would be nice." Soon, to confirm his interpretations from this new use of electrical resistivity, Schwartz will drill a series of wells. Schwartz will present the paper, "Hyd...
