Researchers say they have discovered a new room-temperature ambient-pressure superconductor, but many scientists are unconvinced If rumor has wings, extraordinary scientific claims have a jet engine. Within hours of appearing on the preprint server arXiv.org, two papers by a team of scientists in South Korea generated enormous viral buzz. TheContinue Reading

Here’s why older adults naturally lose muscle mass over time and how regular physical activity and resistance training can help Almost everyone shrinks with old age. Many older adults have more difficulty gaining muscle than they did in their childhood and teenage years. And when it comes to maintaining thatContinue Reading

The Fermi bubbles may have started life as jets of high-energy charged particles MINNEAPOLIS — Bubbles of radiation billowing from the galactic center may have started as a stream of electrons and their antimatter counterparts, positrons, new observations suggest. An excess of positrons zipping past Earth suggests that the bubblesContinue Reading

Astronomers used gravitational lensing and supercomputers to identify the colossal black hole, which is among the largest ever found. Astronomers have discovered one of the largest black holes ever found — an ultramassive monster roughly 30 billion times the mass of the sun — using a space-time trick predicted byContinue Reading
