Scientists: As rainfall changes, tropical plants may acclimate

... idea that natural selection has caused species to diverge into highly specialized niches for nitrogen consumption," the PNAS paper says. That's a positive sign considering that as the Earth warms, some areas of the tropics are widely expected to be wetter, some drier. So, at least one of dozens of variab...

Single molecule extends fat mice lives by reversing gene pathways associated with disease in obese

...vival rates of HC and HCR fed mice groups began to diverge and remained separated by a three to four month span. At 114 weeks of age, 58 percent of the HC fed mice had died, compared to 42 percent of the HCR and SD groups. Presently, the team has found resveratrol to reduce the risk of death from the HC die...

Electric fish in Africa could be example of evolution in action

...of speciation is geographically dependent. Animals diverge into separate species because they become physically isolated from each other. Eventually, genes within each group mutate so that the groups can no longer be considered to be of the same species. Another type of speciation, which many scientists hav...

Choosy females make colourful males

...n. Evolutionary theory predicts that species can diverge if different females choose different characteristics in males. Yet females often pay attention to traits that reveal something about the quality of a male. As a result, females are likely to share the same preferences. In Lake Victoria cichlid fish,...

UCLA study finds same genes act differently in males and females

...c disparity that may explain why males and females diverge in terms of disease risk, rate and severity." "This research holds important implications for understanding disorders such as diabetes, heart disease and obesity, and identifies targets for the development of gender-specific therapies," said Jake Lu...

Wisconsin scientists find a way to make human collagen in the lab

...ollagen that duplicates nature exactly, but we can diverge from that when it is desirable," says Ronald T. Raines, a UW-Madison professor of biochemistry who, with postdoctoral fellow Frank W. Kotch, authored the new PNAS study. Scientists have been seeking a way to make synthetic collagen for at least 30 ...

Molecular fossils uncover link between viruses and the immune system

...t the molecular level. However, as virus sequences diverge rapidly and they do not leave behind physical fossils due to their small size, these methods could not be used in studies of the evolution of viruses. ...
