Red wine may have health benefits against cancer, obesity, aging, and even cavities. Now, a new study may add muscle loss to the list. In tests on rats, a Harvard team found that a red wine compound called resveratrol could help keep astronauts toned during trips in space or life on Mars.

Earth’s closest natural satellite could be producing powerful moonquakes as it cools and shrinks, according to a newly-published study. The scientists behind the research analyzed data from instruments placed by Apollo-era astronauts and more recent data collected by a NASA spacecraft.

The lack of gravity in space means that muscles begin to waste away, and scientists have been studying these health effects on Earth with extended bed-rest experiments. In the latest, those beds will be put in a centrifuge to mimic artificial gravity, to see if that can help offset the issues.

Conventional wisdom has long held that the Milky Way was a flat disk of stars and gas, with a bulge in the middle. But now astronomers have created a more accurate 3D map of the galaxy and found that it’s more warped and twisted than previously thought.

Gravitational waves are ripples in the very fabric of spacetime, caused by some of the biggest cataclysms in the cosmos. Now, an international team of scientists has presented the full catalog of these events, gathered over the last few years across two observation runs.

In recent tests run by the National Institute of Standards and Technology (NIST), experimental atomic clocks have achieved record performance in three metrics, meaning these clocks could help measure the Earth’s gravity more precisely or detect elusive dark matter.

Physics tells us that a hammer and a feather, dropped in a vacuum, will fall at the same rate. Now, CERN scientists are preparing to drop antimatter in a vacuum chamber to see if gravity affects it the same way it does matter – or if antimatter falls upwards instead.

Hungarian astronomers have spotted two new pseudo-satellites – in the form of clouds of dust – caught in the gravitational tug-of-war between the Earth and the Moon.

Gravity.co's Richard Browning has put his extraordinary jet suit on sale and display at British retailer Selfridges. Those without the cash can throw on an HTC Vive headset and learn to fly the thing in virtual reality, where unscheduled landings will be a lot less messy.

The theory of relativity predicts that any two objects in a vacuum will fall at the same rate. Whether or not this applied to massive objects like planets and stars has long been debated, but now astronomers have shown that the phenomenon does hold true, meaning Einstein was right yet again.
