Phys.org / Rare high-resolution observations of a flare-prolific solar active region
Scientists have captured an exceptionally rare, high-resolution view of an active region that produced two powerful X-class solar flares—an achievement rarely possible from Earth. Using the GREGOR solar telescope in Tenerife, ...
Phys.org / The largest ice desert has the fewest ice nuclei worldwide
There are fewer ice nuclei in the air above the large ice surfaces of Antarctica than anywhere else in the world. This is the conclusion reached by an international research team led by the Leibniz Institute for Tropospheric ...
Phys.org / Group 13 elements: The lucky number for sustainable redox agents?
Researchers from The University of Osaka created a reagent for important building-block molecules with an abundant main-group element, gallium. These early findings show that an organic gallium compound can display transition-metal-like ...
Phys.org / 'Stick and glue' method enables more precise biomolecule tracking in cells
A team of researchers at IOCB Prague headed by Dr. Tomáš Slanina has developed a new method for labeling molecules with fluorescent dyes that surpasses existing approaches in both precision and stability. The new fluorescent ...
Phys.org / Nanoscale 'Bragg gratings' on photonic chips suppress noise in laser light
Researchers at the University of Sydney have cracked a long-standing problem in microchip-scale lasers by carving tiny "speed bumps" into the devices' optical cavity in their quest to produce exceptionally "clean" light. ...
Phys.org / Long-term field data reveal warming cuts temperate forest NO and N₂O emissions by altering soil moisture
Researchers from the Institute of Applied Ecology of the Chinese Academy of Sciences and the University of California, Riverside, have investigated how the loss of forest soil gaseous nitrogen (NO, N2O, and N2) is affected ...
Phys.org / Electric control of ions and water enables switchable molecular stickiness on surfaces
What if a surface could instantly switch from sticky to slippery at the push of a button? By using electricity to control how ions and water structure at the solid liquid interface of self-assembled monolayers of aromatic ...
Phys.org / Caribbean rainfall driven by shifting long-term patterns in the Atlantic high-pressure system, study finds
A new study published in Science Advances overturns a long-standing paradigm in climate science that stronger Northern Hemisphere summer insolation produces stronger tropical rainfall. Instead, a precisely dated 129,000-year ...
Phys.org / Astronomers unveil 400 sibling star clusters in the Milky Way
Stars usually form in clusters, which can also form in pairs or groups. Binary clusters (BCs) are defined as pairs of open clusters closely associated both in position and kinematics. They provide insight into how stars form ...
Phys.org / Rare stone tool cache found in Australian outback tells story of trade and ingenuity
About 170 years ago, a large bundle of stone tools was deliberately buried close to a waterhole in the remote Australian outback. Who buried them and for what purpose? Why were they never retrieved?
Phys.org / Advanced tracking uncovers flapper skate hotspots on Scotland's deep seabed
Flapper skate (Dipturus intermedius), the world's largest skate species measuring over two meters in length, live hidden on the rugged seabed around Scotland. Their life in the darkness, deep underwater, makes it extremely ...
Phys.org / Curiosity and focus found to set 'genius' dogs apart in object learning
Curiosity might have killed the cat, but it could prove to be one of the keys to dogs' cognitive abilities, according to a study by the University of Portsmouth's Dog Cognition Center in England and the Friedrich Schiller ...
