Nine out of 10 drugs successfully tested in mice and other animal models ultimately fail to work in people, and one reason may be traced back to a common fact of life for laboratory mice: they’re cold, according to a researcher at the Stanford University School of Medicine…

A discovery published in the March 25 issue of Nature Chemical Biology reveals that biomolecular engineers from Cornell University have discovered that Escherichia coli, a bacteria that is considered to be a severe threat in terms of food safety by restaurateurs, grocers and consumers, is in fact, a friendly bacteria. The researchers discovered that the E…

Researchers say a 3.4 million-year-old fossilized foot found in Ethiopia did not belong to a member of Australopithecus afarensis, the hominin species of our early upright-walking ancestor “Lucy”, but to a tree-climbing hominin cousin with whom she and her relatives co-existed. They write about how they came to this conclusion in the 29 March online issue of Nature…

Later-stage cancers thrive by finding detours around roadblocks that cancer drugs put in their path, but a Purdue University biochemist is creating maps that will help drugmakers close more routes and develop better drugs. Kinase enzymes deliver phosphates to cell proteins in a process called phosphorylation, switching a cellular function on or off…
