Cougars pushed out by wildfires took more risks around roads
After an intense burn in 2018 in California, big cats in the region crossed roads more often. That put them at higher risk of becoming roadkill.

Analyze This: Wildfires are pumping more pollution into U.S. skies
Researchers wanted to study the health effects of wildfire smoke. But they realized they didn’t know where it was and how much exposure people had.

Should we use a genetic weapon against mosquitoes carrying malaria?
One gene drive to eliminate malaria seems to work in the lab. Now it’s time to ask local people if they want it released in the wild.

Some spikes in malaria cases may be tied to amphibian die-offs
Amphibian deaths from a fungal disease may have led to more mosquitoes — and an increase in malaria cases in Costa Rica and Panama.

Some Greenland polar bears are surviving with very little sea ice
The ‘glacial mélange’ on which they’ve come to rely — a mix of ice, snow and slush — could be a temporary refuge for some polar bears.

Electric shocks act like vaccines to protect plants from viruses
To protect crops against viruses in their home country of Taiwan, two teens invented a novel approach to fight blights.

Night lights make even the seas bright
Light from coastal cities and offshore development may shine deep enough to disrupt tiny critters living dozens of meters (yards) below the surface.

Ponds made to control floods can spew climate-warming gases, study finds
Younger stormwater ponds can release more carbon in gases than they absorb, a study finds. That could aggravate global warming.
- Microbes
Kitchen sponges are bacteria’s dream home
Sponges are favorite spots for bacteria, partly because of the mixed-housing environment that the cleaner-uppers offer microbes.
