All eyes are on where hurricanes make landfall, but the massive storms actually cause the most deaths inland, where severe flooding often surprises residents. Now, researchers are learning how to predict where tropical storms and hurricanes will dump the most rain — even days after — and hundreds of miles away from — landfall.

The world is abuzz with the discovery of an extrasolar, Earthlike planet around the star Gliese 581 that is relatively close to our Earth at 20 light years away in the constellation Libra. Scientists have worked on computer models that can provide hints to what comprises the atmosphere of such planets and better-known celestial bodies in our own solar system.

Scientists seeking clues to life on extrasolar planets are studying various biosignatures found in light leaking out to Earth to speculate on what kind of photosynthesis might occur up there and what plants might look like.

An updated analysis of two large randomized clinical trials has found that breast cancer patients who received the monoclonal antibody trastuzumab (Herceptin) along with chemotherapy are living longer and with less risk of recurrent disease, compared to patients treated with chemotherapy alone.

The drug lapatinib shrank tumors and slowed progression of brain metastases in some patients with advanced breast cancer, according to results of a clinical trial recently presented at the annual meeting of the American Society of Clinical Oncology.
