UCI biologist proposes trimming some branches

...-- Australopithecus, Homo and Ardipithecus -- then add one new branch called Praeanthropus. "Specimens that existed in the trimmed branches can be incorporated into this simpler family tree," explained Ayala.

Chemists unlock secret to activating tumor suppressor gene

..., Cho explained. To treat this condition, one must add the PTEN gene to the cell which lacks it, but the resulting PTEN protein must be in its active form, he said. "We discovered what activates the protein and can actually provide activated PTEN. We also discovered how PTEN rapidly degrades in a cell a...

Researchers combine electronics with living cell to create potential toxicity sensor

...Rubinsky. "With the bionic chip, you don't need to add anything, and reactions happen very fast. You simply need two electrodes that measure the current as opposed to some expensive dyes and expensive measurement devices. It's orders of magnitude faster. It's a matter of milliseconds or seconds compared ...

Anthropologist predicts major threat to species within 50 years

... colleagues warn that the United States alone will add at least 10 additional species to the "threatened" list within 50 years. "If other species follow the same pattern as the mammals and birds in our study, then we are facing a serious threat to global biodiversity associated with our growing human pop...

Insulin study sheds light on physics of crystal growth

...ed, Vekilov says. As crystals grow, new molecules add on to the edge of a layer, called a "step." Molecules tend to aggregate and pile up unevenly from one spot on the step, building up in clumps in a process called step bunching. This results in crystals that are generally undesirable for applications ...
