GOES-19 has taken over as NOAA’s primary geostationary eye in the Western Hemisphere, joining GOES‑18 to deliver unprecedented detail on global weather. It tracks hurricanes, atmospheric rivers, wildfires and more with high‑resolution imagery and lightning mapping. Its CCOR‑1 coronagraph keeps watch on the sun, offering forecasters up to three days’Continue Reading
A more nuanced understanding of hormone therapy now suggests that its benefits for heart health depend on how soon after menopause onset it is prescribed. Menopause can have profound effects on heart health, yet many people are unaware of this important connection. The hormonal shifts occurring during menopause mark theContinue Reading
A sample from the asteroid Bennu, collected by the OSIRIS-REx mission, has arrived at London’s Natural History Museum for analysis. Scientists are optimistic that it could contain the seeds of life. A tiny fragment from the most dangerous asteroid in the solar system has arrived in the U.K. — andContinue Reading
Six exoplanets with sizes between Earth and Neptune have been in rhythm with each other since they were born around the same star 4 billion years ago, new research suggests. Astronomers have discovered a remarkable star system with six planets unlike any in our solar system. According to new research,Continue Reading
The results could help scientists understand the complex flows of water and air on Earth Some days really are longer than others. And now scientists know by precisely how much. Using a laser gyroscope, scientists have measured variations in Earth’s rotation rate smaller than a millionth of a percent. TheContinue Reading
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 book explores the tumultuous history of a blood-clotting invention The average human body holds about 5 liters of blood. Lose a liter, and you may go into shock. Lose two more, and you’ll probably die. For doctors treating traumatic injuries, keeping a patient’s blood in their body is “oneContinue 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
