The deep-sea fish ended up with glowing lures not just to snag meals, but also to attract mates, a new study finds.

Scientists have captured stunning new insights into one of the universe’s most powerful phenomena—black hole jets—by using a planet-sized network of radio telescopes. Focusing on Cygnus X-1, one of the first known black holes, they measured jets blasting out with the energy of 10,000 Suns and moving at half the speed of light. By watching these jets get pushed and bent by the fierce stellar winds of a nearby supergiant star, researchers could calculate their true power for the first time.

Caffeine doesn’t just perk up humans—it can sharpen ants’ minds too. Invasive Argentine ants given caffeinated sugar learned to find food much more efficiently, taking straighter paths and reducing travel time by up to 38%. They weren’t faster, just more focused, indicating improved learning. This unexpected effect could make pest control baits far more effective.

With shortages of medical professionals and an aging population, thousands of community health care workers prevent older adults from falling through the cracks.

Engineers at Northwestern University have taken a striking leap toward merging machines with the human brain by printing artificial neurons that can actually communicate with real ones. These flexible, low-cost devices generate lifelike electrical signals capable of activating living brain cells, a breakthrough demonstrated in mouse brain tissue.

As the Moon swallowed the Sun during the April 8, 2024, total solar eclipse, something remarkable happened on the ground—cities went eerily quiet. Scientists analyzing seismic data found that human-generated vibrations, usually caused by traffic, construction, and daily activity, dropped sharply during totality. The effect was so pronounced that it created a clear “seismic hush” across urban areas directly in the eclipse’s path, before quickly rebounding afterward.
