The storms not only threaten people, but also sea ice, which influences the global climate CHICAGO : In January 2022, a cyclone blitzed a large expanse of ice-covered ocean between Greenland and Russia. Frenzied gusts galvanized 8-meter-tall waves that pounded the region’s hapless flotillas of sea ice, while a bombardmentContinue Reading
In How Far the Light Reaches, Sabrina Imbler shows us that the ocean, in all its mystery and dazzling glory, is queer — that is, the life that takes shape there challenges how we landlubbers perceive ways of being. This collection of essays tells the stories of 10 sea creatures,Continue Reading
Low humidity and temperatures may make infections more likely When bitter winds blew and temperatures dropped, my grandmother would urge me to come inside. “You’ll catch your death of cold out there,” she’d say.

The first full moon of the new year will be a ‘micromoon,’ with the moon at its farthest point from Earth. Look up on Jan. 6 for a view of the first full moon of 2023: The Wolf ‘micromoon.’ January’s full moon will be slightly smaller than average because theContinue Reading
A metallic alloy of chromium, cobalt, and nickel is over 100 times tougher than graphene and gets even more resistant to damage at extremely low temperatures. Researchers have proven that a metallic alloy of chromium, cobalt and nickel is officially the toughest material on Earth — more than 100 timesContinue Reading
After many delays, the observatory finally got to work this year This year marked the end of a decades-long wait for astronomers. The James Webb Space Telescope is finally in action.

Polymyxins turn cell membranes into brittle, breakable crystals To kill drug-resistant bacteria, “last-resort” antibiotics borrow a tactic from Medusa’s playbook: petrification. New high-resolution microscope images show that a class of antibiotics called polymyxins crystallize the cell membranes of bacteria. The honeycomb-shaped crystals that form turn the microbes’ usually supple skinsContinue Reading
