Researchers have discovered a way to stop mosquitoes from biting by making them feel full, using drugs designed to suppress human appetites. Neurobiologist Leslie Vosshall says that she decided to take this “completely zany” approach “as kind of a lark”, but now sees promise in the method for controlling mosquito-borne diseases. The next step: design a sufficiently powerful mosquito-specific diet drug that avoids unwanted effects on people.
Quake-prone Myanmar has transformed itself into a leader in seismic monitoring in southeast Asia, using a high-tech network of 21 seismic-monitoring stations dotted around the country. Local and international researchers are working together to help optimize life-saving earthquake and tsunami warnings — although foreign scientists are banned from areas where the government-sanctioned military-led campaign of violence continues against the Rohingya minority group.
The lamprey is known for its resilience: after its spinal cord is severed, it can regrow part of its central nervous system and resume swimming normally. Now, scientists have discovered that the creature can repeat the feat even if the same site is re-injured.
FEATURES & OPINION
Researchers are hunting for “one of the most complex groups of pollutants out there” — fluorochemicals. These carbon chains swaddled in fluorine atoms have a unique ability to repel both grease and water, making them ideal for everything from food wrappings to fire-fighting foams. But they don’t degrade, and some of them have already been banned because of their danger to human health. Now, environmental chemists, epidemiologists and toxicologists are trying to determine just how many variations of these chemicals saturate our environment — and what to do with them.
There is evidence that green tea, or some of its chemical components, can guard against cancer. But after decades of population-based health studies, and even clinical trials in people with cancer, scientists are struggling to translate promising initial results into meaningful benefits.

Researchers have added a new enzyme to their gene-editing toolkit: CRISPR-CasX. Discover the new, smaller CRISPR protein in this week’s podcast. Plus, ultraviolet light reveals that some flying squirrels secretly glow hot pink and researchers are hoping to speed up drug discovery by virtually screening millions of chemicals.
BOOKS & ARTS
