Warming cities may see more rain — and frequent flooding
Scientists are seeking to understand why and how to mop up excess precipitation.

Stores and malls buy into ponds and rain gardens for flood control
An extra bonus: These rainy-day ponds clean up that dirty water running off parking lots.

‘Zombie’ wildfires can reemerge after wintering underground
Climate change may make these not-quite-dead blazes more common. Scientists are learning to predict where a zombie might emerge.

‘Tree farts’ make up about a fifth of greenhouse gases from ghost forests
Heat-trapping gases from dead trees play an important role in the environmental impact of “ghost” forests.

Warning: Wildfires might make you itch
Western wildfires are on the rise due to climate change and land use. Now a study adds eczema to the list of health risks that smoke might trigger.
- Earth
Only 3 percent of Earth’s land is unchanged by people
A sweeping survey of land-based ecosystems finds that very few still support all the animals they used to. Reintroducing lost species could help.

No animal died to make this steak
The ribeye steak is the first of its kind, and the latest in a growing list of meats printed with a 3-D bioprinter instead of being harvested from an animal.

New robots can clean virus-laden surfaces so people won’t have to
Smart and nimble cleaning robots will soon help disinfect spaces. They twist and bend to hit hard-to-reach spaces with UV light or cleansing sprays.

Analyze This: Invasive species cost the world billions each year
A new study estimates that invasive species have cost the world more than $1 trillion since 1970. That’s almost certainly an underestimate.
- Health & Medicine
Urban pollution can pose unseen risks to kids’ immunity and more
A trio of new studies links immune changes and high blood pressure to inhaling bad air.

Can wildfires cool the climate?
Severe wildfires are becoming more common. Science is showing that the tiny particles they release into the air can alter Earth’s temperature — sometimes cooling it.

Unmasking the pandemic’s pollution problem
Discarding all the materials people use to protect themselves from COVID-19 has created a growing environmental problem.
