Diet drugs suppress mosquitoes’ thirst | Nature Briefing
Hello Nature readers,
Today we hear that diet drugs can suppress mosquitos’ thirst for blood, learn how to make the most of Instagram and learn of the search for thousands of fluorinated chemicals in our environment.

Diet drugs suppress mosquitoes’ thirst
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.

Myanmar leads the way in seismic monitoring
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.

Lampreys can regrow their spinal cords twice
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.

How to scrub a non-stick world
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.

Does tea prevent cancer? “Yes, no and perhaps.”
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.

CasX: A new, smaller CRISPR protein
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.

Infographic of the week
Immune cells called neutrophils seem to help breast-cancer cells to spread — or ‘metastasize’ — to the lungs. Proteins (shown as red and blue dots) seem to bind neutrophils to cancer cells that are wandering the body, called circulating tumour cells (CTCs). They form clusters that somehow make CTCs more likely to form tumours in the lungs. Disrupting these clusters might offer a way of fighting metastasis.

Clockwise from top left: a ‘green sun animacule’, likely in the genus Acanthocystis (viewed at 400x under phase-contrast microscopy); a tough tardigrade ‘water bear’, collected from a spring in Florida, that has ingested microbial food (phase-contrast microscopy at 200x); a tardigrade moulting eggs into its shed cuticle; and a ciliate contorted into a heart after feeding on various filamentous algae and cyanobacteria (200x under differential interference contrast microscopy).

Harness Instagram for your science
Don’t shy away from Instagram when considering social networks that can amplify your science. Microbiologists Hunter Hines and Sally Warring offer their case studies for making the most of the image-focused community.
