Phys.org / Vast cluster of ancient galaxies could rewrite the history of star formation
Astronomers have discovered a vast, dense cluster of massive galaxies just 1 billion years after the Big Bang, each forming stars at an intense rate from collapsing clouds of dust. Reported in Astronomy & Astrophysics by ...
Phys.org / Experiments bring Enceladus' subsurface ocean into the lab
Through new experiments, researchers in Japan and Germany have recreated the chemical conditions found in the subsurface ocean of Saturn's moon, Enceladus. Published in Icarus, the results show that these conditions can readily ...
Phys.org / How to prevent charge buildup in a lunar rover
As they roll across shadowed regions of the moon's surface, future lunar rovers could develop hazardous buildups of electric charge on their wheels. Through new analysis published in Advances in Space Research, Bill Farrell ...
Phys.org / Physicists create resilient 3D solitons in the lab
For the first time, physicists in Italy have created a 'lump soliton': an extremely stable packet of light waves which can travel through 3D space, and even interact with other solitons without losing its shape.
Phys.org / Machine learning and microscopy solve 170-year-old mystery of premelting ice
Through a novel combination of machine learning and atomic force microscopy, researchers in China have unveiled the molecular surface structure of "premelted" ice, resolving a long-standing mystery surrounding the liquid-like ...
Phys.org / Physicists push superconducting diodes to high temperatures
For the first time, researchers in China have demonstrated a high-temperature superconducting diode effect, which allows a supercurrent to flow in both directions. Published in Nature Physics, the team's result could help ...
Phys.org / Earlier ultra-relativistic freeze-out could revive a decades-old theory for dark matter
A new theory for the origins of dark matter suggests that fast-moving, neutrino-like dark particles could have decoupled from Standard Model particles far earlier than previous theories had suggested.
