A nearly 13-year-old skin cancer drug rapidly alleviates molecular signs of Alzheimer's diseas e and improves brain function, according to the results of a new mouse study being hailed as extremely promising.

In the race to catch drug cheats, sports officials are turning to more sophisticated tests. Since cheaters are rarely caught red-handed, scientists devised a plan to catch them with the packaging inside their bodies.

For years, scientists have warned that climate change is taking its toll on Earth's ice, thawing not just the massive ice sheets of Greenland and Antarctica but mountain glaciers and ice caps from the Andes to the Alps.

How did the zebra get its stripes? One theory holds that stripes help confuse predators. But stripes might be primarily to protect zebras from ferocious…insects

Observing that certain cancer cells may exhibit greater flexibility than normal cells, some scientists believe that this capability promotes rapid tumor growth. Now computer simulations developed by Boston University Biomedical Engineering Assistant Professor Muhammad Zaman and collaborators at the University of Texas at Austin appear to support this view.

I m about to make an embarrassing (to science fiction fans) confession: until last week, I had never read Dune . I wasn t even aware that I was supposed to have read Dune . Nor did I know I should be embarrassed at the failure.

Biomedical research scientists send proposals to the National Institutes of Health in the hopes of being funded. A recent study of this process, published in Science by the University of Kansas’s Donna Ginther and her colleagues, revealed that proposals from black applicants are significantly less likely to be funded than proposals from white applicants

(PhysOrg.com) -- To learn more about how the sun works, scientists study particles that are emitted from it into space due to thermonuclear reactions that occur inside; by applying known physics principles, they can then deduce which sort of nuclear reactions are taking place. As one example, researchers have been able to identify high energy proton to proton interactions that are described as pp neutrinos by detecting them when they reach Earth.

It's a question that arises with virtually every major new finding in science or medicine: What makes a result reliable enough to be taken seriously? The answer has to do with statistical significance -- but also with judgments about what standards make sense in a given situation.

The Philippine tarsier (Tarsius syrichta) makes ultrasonic calls. (Credit: Nathaniel Dominy, Dartmouth) Let’s be honest: tarsiers look odd. Among the smallest of all primates, most species of tarsier would fit easily in the palm of your hand.
