New insights into chimpanzees, tools, and termites from the Congo basin
...first descriptions of the form and function of two distinct tool sets used by chimpanzees in preying upon termites in central Africa. They differ from technologies observed in other parts of their range. Chimpanzees regularly visit two forms of termite nests and used specific tool sets to extract their insect...New program examines stem cells' potential to repair, replace damaged tissue

A major discovery stemming from this work is that the coelacanth genome appears to be evolving slowly relative to land vertebrates and the teleost fishes.

"There are receptors everywhere, but these mice demonstrate proof of concept that the androgen receptor in bone is responsible for sexually dimorphic skeletons.

...ing new drugs to treat such chronic pain, which is distinct from the relatively short-lived pain from injury, which fades as the injury heals. In their experiments, Bettina Hartmann and her colleagues studied receptors called AMPA receptors, which are triggered by the neurotransmitter glutamate. Such receptor...Researchers discover defense mechanisms in some plants believed bred out by humans
...ists found that BGAF was a hybrid protein with two distinct regions or domains, a disease-response region and a carbohydrate-binding region (lectin). In nature, the two occur as separate proteins, but in all the grass species studied so far, they were fused, probably millions of years ago in the ancestors of ...Menssana research at NJIT receives kudos for FDA-approved breath test

Phillips has proved that these patterns vary with illness and can be used to diagnose a variety of diseases. "It's more than folk medicine," said Phillips....Visualizing the end of the human genome
...t version of the protein, human POT1 contained two distinct OB-folds. The grooves of the two folds align with one another, forming a continuous channel where the telomeric DNA can fit.

...e cells' role in regulating cocaine sensitivity is distinct from its function as a timekeeper. One known effect of cocaine on Drosophila is loss of "negative geotaxis," or wall climbing, in response to startle.
