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.

Warming temps could turn some blue lakes green or brown
Slightly warmer summers could cause thousands of blue lakes to become a murky green or brown, according to a tally of color in 85,000 lakes worldwide.

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.

What does charred ancient poop reveal about early animal-raising?
Evidence from the dung may push the onset of animal raising back 2,000 years earlier than previously thought.
