Phys.org / Bow-and-arrow-shaped radio galaxy discovered by citizen scientist
Astronomers have discovered a "remarkable" bow-and-arrow-shaped radio galaxy with an enormous arc-like structure extending nearly 1.8 million light-years across. The newly identified system, detailed in a new paper published ...
Phys.org / What made prehistoric communities resilient? Ancient social networks may hold the answer
A new study led by Dr. Ariel Malinsky-Buller of the Hebrew University of Jerusalem challenges long-held assumptions about how prehistoric hunter-gatherers survived in the Southern Caucasus between 57,000 and 27,000 years ...
Phys.org / Nanotube-based thermoelectrics open a new pathway to waste-heat energy conversion
Whenever someone asks ChatGPT a question, heat is generated somewhere in the server room—a data center. When an electric vehicle battery generates heat during operation, the heat must be managed continuously. Manufacturing ...
Phys.org / Room-temperature device synchronizes distant laser spots into single coherent 'supermode'
Researchers have demonstrated a new way to make spatially separated lasers synchronize and act as a single coherent light source—without extreme conditions or complex materials.
Phys.org / Artificial light is keeping reef fish awake, and the effects may ripple across coral reefs
Artificial light spilling into coastal waters from cities, ports, roads and hotels is disrupting sleep in coral reef fish and is associated with changes in markers linked to brain health, according to a new study from Bar-Ilan ...
Phys.org / Webb spots the birth of a giant galaxy and a supermassive black hole
Astronomers have used the James Webb Space Telescope to catch an extraordinary glimpse of a massive galaxy taking shape in the early universe. They identified a compact group of at least six galaxies that are likely to merge ...
Phys.org / Arctic shipping alters cloud formation, study finds
A study led by the EPFL suggests that shipping emissions influence climate-relevant cloud formation and may affect regional climate processes far beyond the polar region.
Phys.org / Women negotiate as effectively as men—but leave people happier
Men and women achieve similar economic outcomes in negotiations, but female negotiators foster stronger interpersonal relationships, which lead in turn to greater satisfaction with the result and a greater desire to negotiate ...
Phys.org / Astronomers map a magnetic 'skeleton' funneling gas into a stellar nursery
Stars form when vast clouds of cold gas in space collapse under their own gravity. But not all gas collapses, and not all clouds form stars equally efficiently. A longstanding puzzle in astrophysics is what controls this ...
Phys.org / Seal pups and seabird chicks are suffering in extreme weather. How can we protect them?
Extreme weather is becoming the new normal, disrupting human communities across the globe.
Phys.org / Mosquito-borne viruses avoid killing hosts by limiting protein output, study reveals
The increase in mosquito-borne virus infections is a growing public health concern. Diseases traditionally confined to tropical or subtropical regions, like dengue or West Nile virus, are expanding their geographic scope. ...
Phys.org / Leaf-based fluorescence test speeds search for plant gene-editing targets
Gene editing of plant DNA has the potential to produce crops with increased performance and resilience, but it can take a long time to achieve these gains. To shorten this process, scientists often use screening tools to ...
