The discoveries that led to artemisinin—an antimalarial—and avermectin—a compound that has been used to develop therapies for river blindness and lymphatic filariasis—“are now more than 30 years old,” said David Conway, a professor of biology of the London School of Hygiene & Tropical Medicine. “[These drugs] are still, today, the best two groups of compounds for antimalarial use, on the one hand, and antinematode worms and filariasis on the other.”

ELMEHED. © NOBEL MEDIA AB 2015 Tomas Lindahl, Paul Modrich, and Aziz Sancar won this year’s Nobel Prize in Chemistry for their work elucidating mechanisms of DNA repair. “These guys have [made] tremendous, longstanding contributions to DNA repair, which is what keeps us all alive,” said David Lilley, a professor of molecular biology at the University of Dundee, U.K.

WIKIPEDIA, HGG6996Will scientists figure out how to activate energy-burning brown fat in people to treat obesity? Harvard Medical School’s Bruce Spiegelman believes so. He leads one of several teams looking to target the tissue for potential obesity therapies. From evaluating compounds that fire up brown fat activity in humans to transplanting the tissue from one mouse to another, among other approaches, the field is heating up. But the work is still early stage, and several obstacles must be overcome before any of these experimental approaches reach the clinic.

“We really haven’t pushed the capacity of brown fat in humans yet,” Aaron Cypess of the National Institute of Diabetes and Digestive and Kidney Diseases told The Scientist.

C. BICKEL, SCIENCE TRANSLATIONAL MEDICINELast year, a team led by Martin Bergo at the University of Gothenburg in Sweden showed that the antioxidants N-acetylcysteine (NAC) and vitamin E could spur the growth of lung cancer in mice. This week (October 7), the team showed that the same antioxidants can lead to an increase in metastasis in mice with melanoma. The results were published in Science Translational Medicine.

“Antioxidants can probably protect both healthy cells and tumor cells from free radicals,” Bergo told The Scientist. “Free radicals can slow down ...
