Phys.org / Ganymede's unique magnetic field may be powered by ongoing core formation—not a cooling core
Ganymede is not only Jupiter's largest moon, but also the largest in our solar system and one of the few that hosts a massive ice ocean. Adding to this planet-like moon's uniqueness is the fact that among the hundreds of ...
Phys.org / Non-rotating early galaxy is a surprise to astronomers
Astronomers using the James Webb Space Telescope have made a surprising discovery about a galaxy long, long ago and far, far away: It isn't rotating. That's something only seen in the most massive, mature galaxies that are ...
Phys.org / A close brush with Mars will reshape NASA's Psyche journey in a way few missions attempt
NASA's Psyche spacecraft will get a boost from Mars on Friday, May 15, passing just 2,800 miles (4,500 kilometers) from the planet's surface at some 12,333 mph (19,848 kph). The spacecraft will harness the planet's gravitational ...
Phys.org / Saturday Citations: Psychedelic therapeutics; interoception and well-being; a hidden linguistic bias
This week, researchers reported that the human brain is capable of sophisticated language processing while in an unconscious state during general anesthesia. An informatics and computing professor found that the Climate TRACE ...
Phys.org / Genetics link Angola's 'ghost elephants' to populations hundreds of miles away
For more than a decade, conservation biologist Steve Boyes searched for "ghost elephants"—nocturnal giants rumored to roam a remote, high-altitude wetland in eastern Angola. When a motion-sensor camera finally captured their ...
Phys.org / New catalyst unlocks carbon-free ammonia heat for steel, cement and chemicals
A single-atom platinum catalyst lights ammonia at 200 °C and keeps it burning steadily at 1,100 °C with low NOx, generating high-grade, carbon-free heat for steel, cement and chemicals.
Phys.org / AI cuts wildlife tracking time from months to days
Artificial intelligence can dramatically speed up the painstaking work of tracking wildlife with remote cameras, cutting analysis time from months or even a year to just days while producing nearly the same scientific conclusions ...
Phys.org / This tiny grain-of-rice sensor gives robots a new sense and changes what delicate tools can detect
Researchers have developed a sensor about the size of a grain of rice that can measure forces and twisting motions in all directions using light instead of traditional electronics. The new sensor could help robotic tools ...
Phys.org / Northern Sri Lanka's oldest confirmed settlement reshapes what archaeologists thought about early island life
A study published in the Journal of Island and Coastal Archaeology has identified the earliest evidence of prehistoric occupation by island dwellers of northern Sri Lanka. Long thought to be unsuitable for human occupation ...
Phys.org / The moon's largest impact crater scattered something priceless—and Artemis may be heading straight into it
A new study, published in Science Advances, has refined some important details about the moon's largest and oldest impact crater, which stretches more than 1,200 miles (2,000 km) on the far side of the moon. The new details ...
Phys.org / Spiral galaxy's brilliant heart shines bright in a new picture from NASA's Webb telescope
A spiral galaxy's brilliant heart outshines everything within sight in a new picture from NASA's Webb Space Telescope.
Phys.org / From flying discs to glowing orbs, these newly opened Pentagon files point somewhere stranger than expected
The Pentagon on Friday released a first batch of secret files documenting reported sightings of unidentified flying objects—some dating back to the 1940s—fanning speculation over whether alien life exists.
