Tiny gemstones show when Earth’s crust first started moving
Chemical hints observed in zircons suggest when the important process of plate tectonics first took off.

Cool Jobs: Bringing paleontology to the people
From museums to movies, these three paleontologists totally rock their connections with the public.

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.

Bubbles could help remove trash from rivers
One young engineer devised a way to make bubbles sweep away the trash floating down a creek, like the one in her backyard.

Scientists Say: Atmosphere
An atmosphere is an envelope of gas around a planet, dwarf planet or moon.
- Oceans
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.
