Smash hit: Making ‘diamond’ that’s harder than diamonds
Scientists had suspected extreme meteorite impacts might turn graphite into an unusual type of diamond. Now they’ve seen it happen — in under a nanosecond.

Black hole smashup sent out ‘yottawatts’ of power
When two black holes collided, they released a lot of energy in gravity waves. How much? How about 36 septillion yottawatts of power!

Microbes mine treasure from waste
Like miniature factories, bioreactors house microbes recruited to chew through wastes to clean dirty water, make chemicals or generate electricity.

Scientists ‘see’ thunder for first time
Scientists have captured the first image of thunder. The map shows the relative strengths of the sound waves emanating from the loud clap.

‘Smart’ clothes generate electricity
Scientists in South Korea have developed a fabric that captures energy from its wearer’s motions and turns it into electricity.

How popcorn got its pop
Popcorn is a popular treat. Now, scientists have learned exactly what happens as it pops. They also have come up with an experiment they hope you will try.

Fast sea level rise is a very recent change
Sea levels have been rising for more than a century. But that rise is now speeding up. That suggests that what is driving the rise — climate change — also has increased dramatically in recent years.

A new ‘spin’ on concussions
Scientists have suspected that rotational forces in the brain may underlie concussions. A new study used athletic mouthguards containing sensors. Data on head movements during collisions suggest that a twisting of the brain may underlie mild brain injuries, including concussion.

Machine simulates the sun’s core
A machine heats iron atoms to temperatures that match the interior of the sun. This has helped solve a solar mystery.
