    Sunlight + gold = steaming water (no boiling needed)

    Nano-gold is the new black, at least when it comes to absorbing heat. When tiny gold particles get together, they become energy super-absorbers — turning them black.

    Scientists Say: Yottawatt

    On Earth, scientists measure energy use in watts. When you have lot of those watts — one million billion billion — you have a yottawatt.

    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!

    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.
