Coastal cities around the world are sinking, satellite data show
Of 99 coastal cities studied, nearly one-third are sinking. This leaves coastal communities increasingly vulnerable to rising seas.

A new clock shows how gravity warps time — even over tiny distances
This clock measured how gravity changes the passage of time in different places — even spots just one millimeter apart.

Muons reveal the inner worlds of pyramids, volcanoes and more
Tracking these subatomic particles can uncover surprising hidden structures.

Here’s why cricket farmers may want to go green — literally
Crickets are great sources of protein, but they often kill each other in captivity. Green light could help solve the problem, two teens find.

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.

Analyze This: Corals stash microplastics in their skeletons
Scientists have wondered where the ocean’s microplastic pollution ends up. Corals may trap about 1 percent of particles in tropical waters each year.

A bold plan to save the planet turns carbon dioxide into stone
Scientists hope that capturing carbon dioxide this way will limit both further warming of our planet and an escalation of extreme weather events.
