Phys.org / Reanalysis suggests 'Phoebe' is a variable star, not a primordial black hole
A new study debunks a recent claim that astronomers may have detected a lunar-mass primordial black hole. In a reanalysis of observations from the Dark Energy Camera (DECam), researchers found that the star nicknamed "Phoebe" ...
Phys.org / Himalayan pangolin emerges as distinct species, confirmed with DNA from 19th-century specimen
The pangolin is a midsize mammal found only in Africa and Asia. The pangolins' scales make them unique, but these scales have become their undoing. Pangolins are poached for their scales, making them the most highly trafficked ...
Medical Xpress / Men should speed up slower to avoid 'hitting the wall' in marathons, new research suggests
Male runners may be twice as likely as female runners to suddenly slow down—known as "hitting the wall"—during a marathon, according to a study published in Scientific Reports. The authors suggest that men may be able to ...
Phys.org / Why nanoscale droplets don't coalesce and microscale droplets do
Olive oil and water do not naturally mix. Water molecules are polar, having a net electric dipole moment due to the bend angle of about 104.5° between the two oxygen-hydrogen bonds. Olive oil is nonpolar due to its long hydrocarbon ...
Phys.org / Scourge of satellites lighting up the sky could be mitigated with help of ultra-black coating
Astrophysicists working to tackle the growing impact of satellite constellations have pioneered a new ultra-black coating as one possible way to mitigate the problem.
Phys.org / AI must be built with Indigenous Knowledges, not against them
As Australia marks 50 years of NAIDOC Week, honoring the world's oldest living culture, humanity's newest technology has yet to reckon with a simple principle: "nothing about us, without us." The concern is that artificial ...
Phys.org / Nearby 'Super Earth' may be a better candidate for life than previously thought
Using the Hobby-Eberly Telescope at McDonald Observatory, astronomers have taken a closer look at a nearby exoplanet and discovered it may be more Earth-like than previously thought. The planet, known as GJ 3378b, orbits ...
Tech Xplore / Spintronic hardware unlocks faster, lower-energy optimization, outpacing tested quantum annealers
Solving complex optimization problems is central to many modern technologies, from logistics and financial modeling to chip design, communications and artificial intelligence (AI). However, as these problems grow in size, ...
Phys.org / Could 'Trojan horse'-type microorganisms that exploit symbiotic systems be candidates for new biological pesticides?
Researchers at National Institute of Advanced Industrial Science and Technology (AIST), in collaboration with researchers from The University of Electro-Communications (UEC) and Akita Prefectural University, have discovered ...
Phys.org / Orbitronics clears key hurdle with direct orbital currents, boosting signals 100-fold
Researchers at Johannes Gutenberg University Mainz (JGU) are the first to directly utilize orbital currents without the need for conversion of the orbital current into a spin current.
Phys.org / Walkable, greener neighborhoods linked to better physical and mental health across the U.S.
A new big-data analysis of the U.S. pinpoints how urban design aids the health of city residents—especially when cities provide walking opportunities, greenery and mixed-use streets with a blend of commercial and residential ...
Phys.org / Quiet outings linked to more frequent dangerous wildlife encounters
The more people expand into previously natural areas, the more wildlife and humans step on each other's toes, leading to more interactions that may result in conflict. This includes national parks, where people flock to recuperate ...
