Scientists have successfully used geometrically patterned surfaces to influence the development of stem cells. The new approach is a departure from that of many stem-cell biologists, who focus instead on uncovering the role of proteins in controlling the fate of stem cells.

Early findings suggest a radiation therapy that involves numerous highly-focused and potent radiation beams provides targeted tumor control in nearly all patients, reduces treatment-related illness, and may ultimately improve survival for patients with inoperable non-small cell lung cancer, according to a new study.

The use of prescribed burns to manage Western forests may help the United States reduce its carbon footprint. A new study finds that such burns, often used by forest managers to reduce underbrush and protect bigger trees, release substantially less carbon dioxide emissions than wildfires of the same size.

Scientists argue that anti-obesity drugs fail to provide lasting benefits for health and well-being because they tackle the biological consequences of obesity, and not the important psychological causes of over-consumption and weight gain.
