X-ray lasers enable the discovery of a critical point in water

Using X-ray lasers, researchers at Stockholm University have been able to determine the existence of a critical point in supercooled water at around -63 °C and 1,000 atmospheres. Ordinary water at higher temperatures and lower pressures is strongly affected by the presence of this critical point, causing the origin of its strange properties. The findings […]

Human sperm may get lost in space

Having a baby in space may require a bit more direction, with new Adelaide University research revealing the navigational abilities of sperm are negatively impacted by a lack of gravity. Researchers at the University’s Robinson Research Institute, School of Biomedicine and Freemasons Center for Male Health and Wellbeing investigated how extraterrestrial conditions might influence sperm […]

Quantum experiment shows events may have no fixed order

For the first time, a team of physicists in Austria has carried out an experiment that appears to verify the principle of indefinite causal order: an idea that suggests that timelines of events can exist in multiple orders at the same time. Led by Carla Richter at the Vienna Center for Quantum Science and Technology, […]

Limiting space junk’s threat by predicting its mess in the Earth-moon neighborhood

Debris from moonbound spacecraft has left craters on the lunar surface since the U.S. Apollo missions. But the moon is not used to being surrounded by debris. With an expected resurgence in lunar missions in the coming years, such as the U.S. Artemis II test flight, Purdue University engineer Carolin Frueh is researching how to […]

New framework suggests dark energy could be evolving—and may be linked to the Hubble tension

A team of cosmologists in China has introduced a mathematical framework that investigates two of the deepest mysteries in cosmology at the same time. Publishing their research in The Astrophysical Journal, Yun Chen and colleagues at the Chinese Academy of Sciences suggest their work could pave the way for vital corrections to the current ΛCDM […]

Galactic warming: The ‘car engine-like’ effect heating our Milky Way

Our Milky Way’s halo of hot gas is warmer to the “south” than the “north” because of an internal combustion engine-like effect that is compressing the gas like a piston, a new study has found. Computer simulations reveal that the Large Magellanic Cloud—a satellite galaxy below, or on the south side, of our own—attracts the […]

Dual-rail superconducting qubits generate high-fidelity logical entanglement, study finds

Quantum computers, systems that process information leveraging quantum mechanical effects, could outperform classical computers on some advanced tasks. These systems rely on qubits, the fundamental units of quantum information, that become linked via an effect known as quantum entanglement and share a unified quantum state.

Distant galaxy fades 20-fold in just two decades, challenging how supermassive black holes evolve

An international team led by a researcher at the Chiba Institute of Technology has discovered an extremely rare phenomenon: a galaxy about 10 billion light-years away whose brightness dropped to one-twentieth of its original level in just 20 years. By combining multiwavelength observations with archival data spanning several decades, the researchers concluded that the fading […]

Webb and Hubble share the most comprehensive view of Saturn to date

NASA’s James Webb Space Telescope and Hubble Space Telescope have teamed up to capture new views of Saturn, revealing the planet in strikingly different ways. Observing in complementary wavelengths of light, the two space observatories provide scientists with a richer, more layered understanding of the gas giant’s atmosphere.

‘Cool’ detectors cut neutrino mass upper limit by an order of magnitude

Their mass is extremely low, but how light are neutrinos really? A collaboration comprising German and international research groups has optimized its experiments to determine the mass of these “ghost particles.” In doing so, they succeeded in further adjusting downward the upper limit on the neutrino mass scale that had previously been determined in similar […]
