Tiny solar whirlpools may hold the secret to the sun's blistering corona‎

For the second time in a few weeks, we're writing about research into the temperature gap between the sun's surface and its corona. More and more data from various missions continue to feed this wave of discovery. A new paper by Katariina Nykyri of Embry-Riddle, recently published in The Astrophysical Journal Letters, adds to this growing body of work. She argues that millions of tiny whirlpools scattered across the sun's surface could be the energetic engine driving that temperature difference.

Simulated moon dust turned into LEGO-like blocks for settlements‎

Permanent structures on the moon could start with something already there: lunar dust. New research from the University of Arkansas shows that pure regolith, the loose material that covers the moon, could be 3D-printed into LEGO-like bricks. Using it for construction could reduce what NASA needs to send from Earth as it works toward future lunar settlements.

What a 99-million-year-old feather is telling us about the evolution of flight‎

Long before birds took to the skies, dinosaurs were already sporting feathers. But exactly how they evolved into the sophisticated structures that allow birds to fly remains something of a mystery. Now, the discovery of the longest feather ever found preserved in amber is providing some new clues.

Cool adaptations: How fish survive in the Antarctic Ocean‎

With water temperatures as low as -1.9°C (28.6°F), the Southern Ocean is a place of extreme living conditions. A new study led by Senckenberg researchers shows how fish have adapted to Antarctic temperatures. The researchers used the Antarctic spiny plunderfish (Harpagifer antarcticus) as a model organism and, for the first time, analyzed the maternal and paternal copies of its genome separately. This allowed them to uncover mechanisms that contribute to this group of fishes' adaptation to extreme cold.

Laser-driven magnetic state defies equilibrium rules‎

Researchers at the Department of Energy's (DOE's) Oak Ridge National Laboratory (ORNL) and their collaborators used lasers and neutrons to observe a long-lived quantum state in a magnetic material, opening a new way to study materials systems driven far from their equilibrium. Manipulation of quantum magnets is important for advancing quantum information science and could reduce loss of transported information, improve memory devices and benefit other quantum technologies.

Severe ocean risks threaten food prices, pensions and global economic resilience‎

Ocean risks are already severe and worsening, with the potential to become catastrophic without a change of course, according to a new report from the Institute and Faculty of Actuaries (IFoA), the University of Exeter and The Ocean Race.

LHC collaboration presents first result in the hunt for 'quirks'‎

An international collaboration of physicists has presented its first results in its search for hypothetical particles that could help to explain the vast disparity between the strength of gravity and the three fundamental forces described by the Standard Model. Following three years of data collection at the Large Hadron Collider (LHC)'s FASER experiment, the FASER Collaboration found no evidence for these heavy, slow-moving "quirks."

Crystal boundaries help hydrogen sensors work in hot, humid air‎

Hydrogen could play an important role in cleaner energy systems, but even small leaks can create safety risks. Reliable sensors are therefore essential wherever hydrogen is produced, stored, transported or used. A persistent problem is humidity: water molecules can cover the active surfaces of hydrogen detectors and prevent them from responding accurately, particularly in hot, moisture-rich environments.

Researcher uses AI to predict probabilities for chemical processes‎

Quantum chemistry can be used to calculate the probabilities of which chemical processes will occur. This involves a great deal of programming work. Dr. Michael F. Peintinger from the Mulliken Center for Theoretical Chemistry at the University of Bonn has investigated what happens when artificial intelligence is used for this purpose. His work is published in the Journal of Computational Chemistry.
