Astronomers have discovered that winds from a supermassive black hole are about 100 times more powerful than previously thought. XRISM observations showed the resulting turbulence spreading roughly 300,000 light-years, extending far beyond the black hole’s host galaxy. The energy involved rivals several billion supernova explosions, revealing just how dramatically black holes can influence the space around them.

Climate change is often discussed in terms of rising temperatures, extreme weather and environmental loss. But there's another consequence that can be harder to see: The impact on our mental health.In this exclusive video, we explore how heat exposure influences mental state, drawing on research by Kim Meidenbauer, a neuroscientist at Washington State University who studies the effect of heat on emotion and behavior.Editor's Note: This text was updated at 12:30 p.m. EDT to correct the spelling of Kim Meidenbauer's name.Burning up: How can we adapt to a warming world?As the planet warms, our environment will be transformed, but so will our bodies. This video is part of a series where we inves...
QUICK FACTSWhere is it? Lake Pueyrredón and Lake Posadas, Argentina [-47.41961002, -71.87622200]What's in the photo? The point where two different-colored lakes meetWho took the photo? An unnamed astronaut on board the International Space StationWhen was it taken? Sept. 15, 2020This eye-catching astronaut photo shows the point where an ancient Patagonian lake has been split by a peculiar land bridge, creating two contrastingly colored bodies of water.Lake Pueyrredón (on the left in the photo) is the Argentine half of a roughly 40-mile-long (65 kilometers) glacial lake, which stretches across the country's border with Chile in Patagonia — a region in South America that is well known for its d...
The flesh eating New World screwworm has returned to the United States, threatening livestock, wildlife, pets and potentially people as it spreads north. A new UC San Diego tracking system aims to predict where the parasite could strike next while officials revive the eradication strategy that defeated it decades ago.

Sleep app tracks link between air pollution and a bad night’s sleep Sarah Collins Tue, 09/15/2026 - 10:00 Researchers from the University of Cambridge, Tsinghua University and the sleep technology company Sleep Cycle analysed coughing sounds from 32 cities in 12 countries over 500 days, and found that higher daily air pollution levels were strongly linked to nighttime coughing levels, even where local pollution levels were below the World Health Organization’s recommended daily exposure limit. The researchers used cough sounds passively recorded by the mobile app via the phone’s microphone. Cough sounds were counted on individual devices and pooled by city to build an unprecedented dataset o...
