By the end of Friday (March 19), the U.S. will have administered 100 million doses of coronavirus vaccine since President Joe Biden was inaugurated, a milestone that his administration initially pledged to reach by its hundredth day in office. “I’m proud to announce that tomorrow, 58 days into our administration,Continue Reading
The computing power needed can use a lot of energy and spew lots of carbon dioxide. Artificial intelligence — or AI — is the computer code that allows a machine to do something that normally requires a human brain. On TikTok, for instance, AI sorts the posts so that theContinue Reading
Africa is the continent most vulnerable to the impact of climate change. That’s largely because many of its people and governments are too poor to do what’s needed to cope under the expected new conditions. Yet Africa has a long and successful history of learning to live with changing climates.Continue Reading
Rocks collected in Greenland may hold traces of an ancient magma ocean that bubbled over much of Earth’s surface soon after the planet’s birth, a new study finds. Scientists gathered the rocks from the Isua supracrustal belt, a region in southwest Greenland where the exposed rocks are between 3.7Continue Reading

It’s our constant companion, and influences life on Earth in ways big and small The moon is more than a bright, beautiful orb in the night sky. Our nearest neighbor also plays a big part in making the Earth a good place to live. Located an average of only 384,400Continue Reading
Scientists have identified the 19th form of water ice. The exotic, four-sided crystals of this rare ice variety, now dubbed ice XIX, form at ultra-low temperatures and ultra-high pressures. It only exists in laboratory experiments, but researchers say it reveals more about other forms of ice, which can be foundContinue Reading
Earth might have more layers than scientists thought. New research finds that there may be a hidden layer inside the Earth’s solid inner core — an inner-inner core, if you will. The precise nature of this layer is mysterious, but it could have something to do with changes in theContinue Reading
This is the condition in the atmosphere at a particular place and time. Weather (noun, “WEH-ther”) Weather refers to the state of the atmosphere in a particular place and at a particular time. People might talk about the weather in terms of the temperature, air pressure, wind speed or howContinue Reading
One simple rule of thumb: Give more than you take. Soil didn’t always exist. It grew slowly over the millennia as rocks weathered into smaller particles and dust. As land-dwelling organisms died, their decaying bodies added nutrients that would help glue particles together and absorb moisture. Soil science can nowContinue Reading
