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 ...

Scientists drilling deep beneath Greenland's ice have uncovered a startling clue about its past--and future. Evidence shows that the Prudhoe Dome, a major high point of the ice sheet, completely melted around 7,000 years ago during a relatively mild ...

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 .. ...

Some of the ocean's fastest and most fearsome predators--like great white sharks and tuna--are running hotter than expected, and it's costing them dearly. New research shows these warm-bodied fish burn nearly four times more energy than cold-blooded ...

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, .. ...

Researchers have shown that blending quantum computing with AI can dramatically improve predictions of complex, chaotic systems. By letting a quantum computer identify hidden patterns in data, the AI becomes more accurate and stable over time. The .. ...

A surprising new study suggests that eating a very healthy diet--packed with fruits, vegetables, and whole grains--might be linked to a higher risk of lung cancer in younger non-smokers. Researchers found that patients under 50 diagnosed with lung .. ...

Long before rising seas swallowed Doggerland beneath the North Sea, this lost landscape may have been a surprisingly lush and life-friendly haven. New DNA evidence reveals that forests of oak, elm, and hazel were already thriving there more than 16 . ...

A hidden threat is emerging in the world's glaciers: while most are shrinking, a rare group known as "surging glaciers" can suddenly accelerate, unleashing powerful and sometimes destructive events. Scientists have identified over 3,100 of these ...

A new quantum sensing approach could dramatically improve how scientists measure low-frequency electric fields, a task that has long been limited by bulky setups and blurry resolution. Instead of relying on traditional vapor-cell methods, researchers ...
