When dominoes fall, how fast the row topples depends on friction
Two types of friction help determine how quickly a line of dominoes collapses, computer modeling shows.

To test for COVID-19, a dog’s nose can match a nose swab
Dogs can sniff out COVID-19 cases as well as PCR tests can — and are better at ID’ing cases having no symptoms, a new study finds.
- Tech
This robotic finger is covered in living human skin
The advance brings super realistic cyborgs one small step closer to reality.

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.
- Earth
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.

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.
