The COVID-19 pandemic is a stark reminder that we move through a world shaped by unseen life. Bacteria, viruses, and other microscopic organisms regulate the Earth's vital functions and resources, from the air we breathe to all our food and most of our energy sources. An estimated one-third of the Earth's microbes are literally hidden, buried in sediments deep below the ocean floor. Now,...
More than a thousand years ago, people from across the Southeast regularly traveled to a small island on Florida's Gulf Coast to bond over oysters, likely as a means of coping with climate change and social upheaval.
Army researchers predict quantum computer circuits that will no longer need extremely cold temperatures to function could become a reality after about a decade.
If it were not for the fact that the Hubble Space Telescope was designed to be repaired and upgraded while in orbit, it would not have reached its 30th anniversary this month. But repair isn't possible with its $10 billion successor. Bob McDonald explains the implications in his...
CAPE CANAVERAL, Fla. — NASA and SpaceX on Friday urged everyone to stay home for the first home launch of astronauts in nearly a decade because of the coronavirus pandemic. Top officials warned the public against traveling to Florida for the May 27 launch of two NASA astronauts aboard a SpaceX rocket to the International Space Station. It will be the first launch of astronauts from...
Mars had a global magnetic field much earlier -- and much later -- than previously known. Analysis of new satellite data found clear evidence of a magnetic field coming from a lava flow that formed less than 3.7 billion years ago, half a billion years after many people thought the Martian dynamo had ceased. The researchers also detected low-intensity magnetic fields over the Borealis Basin,...

The mechanism underlying Parkinson's dyskinesia has been unknown, until now. An international collaboration has found a key cause, and with it, potentially, a new route to providing relief.

Plastic gives us a lightweight, strong and inexpensive material to use, but it has also caused the plastic apocalypse. Much of the unrecycled plastic waste ends up in the ocean, Earth's last sink. Broken down by waves, sunlight and marine animals, a single plastic bag can become 1.75 million microplastic fragments. Those microplastics might finally end up in our bodies through the fish we eat or...
Mars had a global magnetic field much earlier—and much later—in the planet's history than scientists have previously known.
The first step in many light-driven chemical reactions, like the ones that power photosynthesis and human vision, is a shift in the arrangement of a molecule's electrons as they absorb the light's energy. This subtle rearrangement paves the way for everything that follows and determines how the reaction proceeds.
Using the most advanced Earth-observing laser instrument NASA has ever flown in space, scientists have made precise, detailed measurements of how the elevation of the Greenland and Antarctic ice sheets have changed over 16 years.
Native bees that boost food crops are in decline but changing fire management policies could help them.
