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.
- Animals
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.

New recycling technologies could keep more plastic out of landfills
Recycling plastics is really hard — especially into useful materials. But new chemical tricks could make recycling easier.
- Climate
The world wastes roughly a sixth of the food produced each year
A new United Nations report shows where wastes can be reduced, which would decrease hunger and emissions of climate-warming greenhouse gases.
