In the animal kingdom, everything is not as it seems. Individuals of the same species can look very different from each other — what biologists term “polymorphism.” Sometimes the number of distinct visible forms — “exuberant polymorphisms” — in a single animal population can reach double figures. But why? Scientists have now developed computer models [...]

Scientists have tracked down a powerful set of cells in bladder tumors that seem to be primarily responsible for the cancer’s growth and spread using a technique that takes advantage of similarities between tumor and organ growth. The findings could help scientists develop new ways of finding and attacking similar cells in other types of [...]

By accurately modeling Earth’s last major global warming — and answering pressing questions about its causes — climatologist are unraveling the intricacies of the kind of abrupt climate shifts that may occur in the future.
Investigators have made the first comparative, large-scale phosphoproteomic analysis of human embryonic stem cells (hESCs) and their differentiated derivatives.
Computational biologists have developed an analytical technique to detect the multiple genetic variations that contribute to complex disease syndromes such as diabetes, asthma and cancer, which are characterized by multiple clinical and molecular traits.

Burning of fossil fuels pumps chemicals into the air that react on surfaces such as buildings and roads to create photochemical smog-forming chlorine atoms, scientists report in a new study. The newfound chemistry should be added to atmospheric models, researchers say.
Researchers believe conventional vaccine strategies should not be the only avenue explored in the development of an effective AIDS vaccine. Based on studying simian immunodeficiency viruses in African nonhuman primates, they propose an additional new approach to the AIDS vaccine research agenda. Unraveling how African nonhuman primates adapt to HIV-like viruses may lead to vaccine.

Scientists have elucidated how the stability of the REDD1 protein is regulated. The REDD1 protein is a critical inhibitor of the mTOR signaling pathway, which controls cell growth and proliferation.
