AI-powered personas are becoming so realistic that they can infiltrate online communities and subtly steer public opinion. Unlike traditional bots, they adapt, coordinate, and refine their messaging at a massive scale, creating a false sense of ...

After two centuries of failed attempts, scientists have finally grown dolomite in the lab, cracking a long-standing geological puzzle. They discovered that the mineral's growth stalls because of tiny defects--but in nature, those flaws get washed ...

Scientists have developed a fuel cell that uses microbes in soil to produce electricity. The device can power underground sensors for tasks like monitoring moisture or detecting touch, without needing batteries or solar panels. It works in both dry . ...

A surprising breakthrough in physics could reshape the future of computing by tapping into a strange, previously untapped property of matter. Scientists have shown that tiny atomic vibrations--called chiral phonons--can directly transfer motion to .. ...

Astronomers have long been puzzled by a cosmic mystery: planets orbiting two stars--like Star Wars' Tatooine--are surprisingly rare, even though they should be common. New research suggests the culprit is none other than Einstein's theory of general ...

Calling AI things like "smart" or saying it "knows" something might sound harmless, but it can quietly mislead people about what AI actually does. A new study shows that news writers are more careful than expected, rarely using strongly human-like .. ...

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 .. ...

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 .. ...

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 .. ...
