The National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Prediction Center (SWPC) has issued a G2 geomagnetic storm warning for March 19 due to possible impact from a coronal mass ejection (CME). Geomagnetic storms are classified using a G-scale, which …

The scan takes about half an hour. You lie still while a radioactive tracer courses through your blood and binds to abnormal proteins in your brain, and the machine maps where those proteins have accumulated. It’s the most sensitive early-warning …

You can save money and help save the planet by buying used or refurbished electronics instead of new devices. Since most of the environmental impact of devices comes from the manufacturing phase, buying secondhand gear can reduce your carbon footprint. …

In northern Vermont, where I live, old newspaper clippings show pictures of people driving trucks across Lake Champlain. Those icy, ephemeral corridors, though, seem like relics of a bygone era. Roughly half a century ago, maybe more, the region started …

We’ve all instinctively clung to another person when frightened, if only as a child clutching our mother’s hand. But if that person is scared, too, this behavior may not have the desired calming effect. And a new study, published in …

Planets drifting unmoored through interstellar space, with no star to call home, may still have moons that are warm enough to support life, a new study has found. Through a combination of a thick hydrogen atmosphere and internal heating generated …

The advent of farming led to new evolutionary pressures on humans CHRISTIAN JEGOU/SCIENCE PHOTO LIBRARY A study combining the growing number of ancient genomes from living people has given us our best picture yet of how humans have evolved over …

A new pair of molecular tools is allowing scientists to uncover how plants and fungi coordinate their ancient underground partnership. For about 450 million years, plants and soil fungi have maintained a mutually beneficial partnership. The fungi grow through plant …

For many years, nuclear physicists believed that “Islands of Inversion” were found mainly in isotopes packed with extra neutrons. These unusual regions of the nuclear chart are places where the normal structure of atomic nuclei suddenly stops following the expected …
