Exercise doesn't just challenge the body; it challenges how the brain interprets effort. Scientists discovered that vibrating tendons before cycling allowed people to push harder without feeling like they were working more. Their muscles and hearts . ...

Scientists have detected a surprisingly hot galaxy cluster dating back to the universe's infancy. The cluster formed far earlier and burned far hotter than current models predict. Researchers believe supermassive black holes may have rapidly heated . ...

Europa's buried ocean has made it one of the most exciting places to search for life beyond Earth. However, new calculations suggest its seafloor may be calm, cold, and largely inactive, with little energy to support living organisms. Unlike Jupiter ...

Researchers have built a new platform that produces ultrashort UV-C laser pulses and detects them at room temperature using atom-thin materials. The light flashes last just femtoseconds and can be used to send encoded messages through open space. The ...

Researchers at TU Wien have discovered a quantum system where energy and mass move with perfect efficiency. In an ultracold gas of atoms confined to a single line, countless collisions occur--but nothing slows down. Instead of diffusing like heat in ...

Tessellations aren't just eye-catching patterns--they can be used to crack complex mathematical problems. By repeatedly reflecting shapes to tile a surface, researchers uncovered a method that links geometry, symmetry, and problem-solving. The ...

Around the bright star Fomalhaut, astronomers spotted glowing clouds of debris left behind by colossal collisions between large space rocks. One of these clouds was even mistaken for a planet before slowly fading away. Seeing two such events in just ...

Bariatric surgery far outperformed GLP-1 weight loss drugs in a new real-world comparison of more than 50,000 patients. Two years after treatment, surgery patients lost about 58 pounds on average, while those using semaglutide or tirzepatide lost ...

Researchers in Japan built a miniature human brain circuit using fused stem-cell-derived organoids, allowing them to watch the thalamus and cortex interact in real time. They found that the thalamus plays a decisive role in maturing the cortex and .. ...

Researchers have reconstructed ancient herpesvirus genomes from Iron Age and medieval Europeans, revealing that HHV-6 has been infecting humans for at least 2,500 years. Some people inherited the virus directly in their DNA, passing it down across .. ...
