The report, “Convergence: The Future of Health,” calls for more integration of physical, life sciences for revolutionary advances in biomedical research. What if lost limbs could be regrown? Cancers detected early with blood or urine tests, instead of invasive biopsies? Drugs delivered via nanoparticles to specific tissues or even cells, minimizing unwanted side effects? While such breakthroughs may sound futuristic, scientists...

Previous exposure to the dengue virus may increase the potency of Zika infection, according to research from Imperial College London. The early-stage laboratory findings, published in the journal Nature Immunology, suggests the recent explosive outbreak of Zika may have been driven in part by previous exposure to the dengue virus.

Male mice appear to be precisely wired to know when they are intruders in another male's territory, according to a study published June 23 in Cell Reports. The smell gives it away. But this study found that a genetically specific cluster of hypothalamic cells is wired to the olfactory system and responds only when a male mouse enters another male's cage.

The reason why treadmill training can boost memory recall remains an active area of investigation. A couple of proteins have been shown to fuel exercise-induced neuron growth, but a June 23 study in Cell Metabolism presents a new candidate, cathepsin B--one that can be directly traced from the muscles to the brain in mice. Also, after a run, protein levels increased in blood in mice, monkeys, and humans.

As people get older, they become choosier about how they spend their time and with whom they spend it. Now, researchers reporting in the Cell Press journal Current Biology on June 23 find, based on a series of experimental and behavioral studies, that similar changes take place in Barbary macaques. The findings offer an evolutionary perspective on why aging humans behave as they do, according to the researchers.
