NASA's NICER finds X-ray boosts in the Crab Pulsar's radio bursts
A global science collaboration using data from NASA's Neutron star Interior Composition Explorer (NICER) telescope on the International Space Station has discovered X-ray surges accompanying radio bursts from the pulsar in the Crab Nebula. The finding shows that these bursts, called giant radio pulses, release far more energy than previously suspected.

More than 5,000 tons of extraterrestrial dust fall to Earth each year
Every year, our planet encounters dust from comets and asteroids. These interplanetary dust particles pass through our atmosphere and give rise to shooting stars. Some of them reach the ground in the form of micrometeorites. An international program conducted for nearly 20 has determined that 5,200 tons per year of these micrometeorites reach the ground.

Corals carefully organize proteins to form rock-hard skeletons
Scientists have shown that coral structures consist of a biomineral containing a highly organized organic mix of proteins that resembles what is in our bones. Their study shows that several proteins are organized spatially -- a process that's critical to forming a rock-hard coral skeleton.
