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.

A disinfectant made from sawdust knocks out deadly microbes
It’s made by pressure-cooking sawdust and water, is cheap and easy to make — and could lead to greener cleaning products than chemicals used today.

Satellites find big climate threats — ultra-emitters of methane
Eyes in the sky show many of the worst methane emitters are in countries that produce a lot of oil and gas, such as Russia and the United States.
