Mars may have captured and split a comet to create its two moons
Mars has two irregularly shaped moons, an inner moon named Phobos and an outer moon named Deimos NASA/JPL-Caltech/GSFC/Univ. of Arizona The two moons of Mars may once have been a single comet that was ensnared and split by the planet – and an upcoming mission could find out for certain. How Mars got its two […]
Early galaxy seen by JWST contains giant young stars and supernovae
GLASS-z12, a very early galaxy viewed by the James Webb Space Telescope Naidu et al, P. Oesch, T. Treu, GLASS-JWST, NASA/CSA/ESA/STScI Astronomers have used the James Webb Space Telescope (JWST) to reveal extraordinary details about a galaxy in the early universe, seen as it was just 360 million years after the big bang. Since […]
Spreading rock dust on farms boosts crop yields and captures CO2
We already have evidence that rock dust can remove carbon dioxide from the air – now there are signs that spreading the dust on farm fields also enhances crop growth Source link
Implantable battery is charged up by the body’s oxygen supply
Medical implants often require battery power Sebastian Kaulitzki/Science Photo Library Batteries designed to run on oxygen from inside the body could last months or years before needing to be recharged or replaced, and might one day power everything from pacemakers to brain implants. Xizheng Liu at Tianjin University of Technology in China and his colleagues […]
This robot predicts when you’re going to smile – and smiles back
The Emo robot mimics people’s facial expressions Yuhang Hu A humanoid robot can predict whether someone will smile a second before they do, and match the smile on its own face. The creators hope the technology could make interactions with robots more lifelike. Although artificial intelligence can now mimic human language to an impressive degree, […]
NASA’s Artemis astronauts will try to grow plants on the moon
An artist’s concept of an Artemis astronaut deploying an instrument on the lunar surface NASA NASA has selected the first science experiments that astronauts will bring to the moon as part of the Artemis III mission. This mission, currently planned for 2026, will mark the first time humans have walked on the lunar surface since […]
How mastering the art of being alone can boost your mental health
RECENTLY, I was walking alone on a quiet, winding trail. The path was hard to follow and slick with snow. The sun felt warm on my face. As I trudged uphill, I missed my partner, but felt grateful to be visiting my sister who I don’t see often. I was on my own for a […]

Graviton: We’ve glimpsed something that behaves like a particle of gravity
Have we spotted hints of gravitons? zf L/Getty Images Physicists have been searching for gravitons, the hypothetical particles thought to carry gravity, for decades. These have never been detected in space, but graviton-like particles have now been seen in a semiconductor. Using these to understand gravitons’ behaviour could help unite the general theory of relativity […]
