Mar. 20, 2024 Astronauts have been able to track their muscle health in spaceflight for the first time using a handheld device, revealing which muscles are most at risk of weakening in low gravity conditions. ...
Mar. 19, 2024 Simulated effects of microgravity, created by 60 days of constant bed rest, severely disrupts rhythmic gene expression in humans, according to a new ...
Mar. 18, 2024 Astronomers have charted the largest-ever volume of the universe with a new map of active supermassive black holes living at the centers of galaxies. Called quasars, the gas-gobbling black holes are, ...
Mar. 14, 2024 The period that liquid water was present on the surface of Mars may have been shorter than previously thought. Channel landforms called gullies, previously thought to be formed exclusively by liquid ...
Mar. 13, 2024 What do margaritas, vinegar, and ant stings have in common? They contain chemical ingredients that NASA's James Webb Space Telescope has identified surrounding two young protostars known as IRAS ...
Mar. 13, 2024 Space travel and zero gravity can take a toll on the body. A new study has found that astronauts with no prior history of headaches may experience migraine and tension-type headaches during long-haul ...
Mar. 13, 2024 Physicists often turn to the Rayleigh-Taylor instability to explain why fluid structures form in plasmas, but that may not be the full story when it comes to the ring of hydrogen clumps around ...
Mar. 13, 2024 A deeply eroded giant volcano, active from ancient through recent times and with possible remnants of glacier ice near its base, had been hiding near Mars' equator in plain sight. Its discovery ...
Mar. 13, 2024 Through steady advances in the development of quantum computers and their ever-improving performance, it will be possible in the future to crack our current encryption processes. To address this ...
Mar. 13, 2024 New, highly stretchable sensors can monitor and transmit plant growth information without human intervention. The polymer sensors are resilient to humidity and temperature, can stretch over 400% ...
Mar. 12, 2024 Sand ripples are symmetrical. Yet wind -- which causes them -- is very much not. Furthermore, sand ripples can be found on Mars and on Earth. They would be even more fascinating if the same effect ...
Mar. 12, 2024 For telescopes operating in the vacuum of space, or optical equipment in extreme environments, existing coatings are often insufficient. Researchers have turned to atomic layer deposition and ...
Mar. 11, 2024 The formation of stars and the chaotic environments they inhabit is one of the most well-studied, but also mystery-shrouded, areas of cosmic investigation. The intricacies of these processes are now ...
Mar. 11, 2024 When you are trying to solve one of the biggest conundrums in cosmology, you should triple check your homework. The puzzle, called the 'Hubble Tension,' is that the current rate of the ...
Mar. 8, 2024 As more people seek to go where no man has gone before, researchers are exploring how forensic science can be adapted to extraterrestrial environments. A new study highlights the behavior of blood in ...
Mar. 7, 2024 Sound waves thought to be from a 2014 meteor fireball north of Papua New Guinea were almost certainly vibrations from a truck rumbling along a nearby road, new research shows. The findings raise ...
Mar. 7, 2024 The James Webb Space Telescope makes one of the most unexpected findings within its first year of service: A high number of faint little red dots in the distant Universe could change the way we ...
Mar. 6, 2024 Neutron star mergers are a treasure trove for new physics signals, with implications for determining the true nature of dark matter, according to ...
Mar. 6, 2024 A galaxy that suddenly stopped forming new stars more than 13 billion years ago has been observed by astronomers. Using the James Webb Space Telescope, astronomers have spotted a 'dead' ...
Mar. 5, 2024 Space weather experts are urging regulators and space tourism innovators to work together to protect their passengers and crews from the risks of space weather radiation ...
