Phys.org / Alaknanda: JWST discovers massive grand-design spiral galaxy from the universe's infancy
A spiral galaxy, shaped much like our Milky Way, has been found in an era when astronomers believed such well-formed galaxies could not yet exist. Two astronomers from India have identified a remarkably mature galaxy just ...
Phys.org / Cats adjust their communication strategy by meowing more when greeting men
As many cat owners will testify, their pets are often mysterious creatures, independent, cunning and sometimes aloof. And now it appears that when it comes to communication, they might be playing favorites. A new study published ...
Phys.org / Geodesic approach links quantum physics and gravitation
It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is described extremely well by quantum theory, while the world of gravitation is captured by Einstein's ...
Phys.org / Sugars, 'gum,' stardust found in NASA's asteroid Bennu samples
The asteroid Bennu continues to provide new clues to scientists' biggest questions about the formation of the early solar system and the origins of life. As part of the ongoing study of pristine samples delivered to Earth ...
Phys.org / Ancient stalagmite provides insights into how climate affected early communities in cradle of civilization
The Fertile Crescent, a boomerang-shaped region spanning modern-day Middle Eastern countries, is considered the cradle of civilization and where farming first emerged. But little is known about how climate change influenced ...
Phys.org / Chesapeake Bay's storm surge tides can be 47% higher than the open ocean
When hurricanes or strong storms sweep up the United States' East Coast and meet the shores of the country's largest estuary, Chesapeake Bay, the familiar pattern of storm activity gets a little more complicated. A new study, ...
Phys.org / Astronomers confirm low-luminosity active galactic nucleus in nearby galaxy NGC 3221
Using ESA's XMM-Newton satellite, astronomers from Stanford University and elsewhere have conducted deep X-ray observations of a nearby galaxy known as NGC 3221. The new observational campaign detected a faint active galactic ...
Phys.org / New palladium-gold alloy catalyst boosts methane-to-ethylene conversion with solar power
Researchers just hit two benefits with one catalyst. They converted methane (CH4), a potent greenhouse gas, into ethylene (C2H4), a highly demanded raw material in industrial sectors, using sunlight and a newly designed palladium–gold ...
Phys.org / Single-photon teleportation achieved between distant quantum dots for the first time
An international research team involving Paderborn University has achieved a crucial breakthrough on the road to a quantum internet. For the first time ever, the polarization state of a single photon emitted from a quantum ...
Phys.org / Physicists overcome fundamental limitation of acoustic levitation
Using sound to get objects to float works well if a single particle is levitated, but it causes multiple particles to collapse into a clump in mid-air. Physicists at the Institute of Science and Technology Austria (ISTA) ...
Phys.org / Euclid dataset of a million galaxies proves connection between galaxy mergers and AGN
Astronomers have long debated the role of galaxy mergers in powering active supermassive black holes. Now an unprecedented dataset of a million galaxies from the Euclid telescope provides evidence that mergers play a dominant ...
Phys.org / Historical geography helps researchers solve 2,700-year old eclipse mystery
An international team of researchers has used knowledge of historical geography to reexamine the earliest datable total solar eclipse record known to the scientific community, enabling accurate measurements of Earth's variable ...
