By Remy Tumin For more than 30 years, the world’s largest iceberg was stuck in the Antarctic. Five times the size of New York City’s land area and more than 1,000 feet deep, the mammoth piece of ice finally became loose in 2020 and began a slow drift toward the Southern Ocean. Now, A23a, as it’s known, is spinning in place. After leaving Antarctic waters, the iceberg got stuck in a vortex over a seamount, or an underwater mountain. Imagine a piece of ice about 1,500 square mi

By Catrin Einhorn This generation will probably see the demise of the Great Barrier Reef unless humanity acts with far more urgency to rein in climate change, according to scientists in Australia who released new research on heat in the surrounding ocean. The Great Barrier Reef is the largest coral reef system in the world and is often called the largest living structure on Earth. The study, published last Wednesday in the journal Nature, found that recent extreme temperature

By Kenneth Chang When a NASA spacecraft passes over Shackleton Crater on the moon and peers in, it sees a sea of blackness. The sun never rises high above the horizon, and the rim of Shackleton blocks the sun’s rays from ever shining directly onto the crater floor. There are more than 300 such craters on the moon, and the darkness hides an intriguing mystery: oases of frozen water, which could provide a key resource for astronauts living there in the future. Scientists have n

By Carl Zimmer For generations, physicists have puzzled over life. Their theories about matter and energy have helped them understand how the universe produced galaxies and planets. But physicists have struggled to understand how lifeless chemical reactions give rise to the complexity stored in our cells. In a new book, “Life as No One Knows It: The Physics of Life’s Emergence,” out Tuesday, Sara Walker, a physicist at Arizona State University, offers a theory that she and he
