Phys.org / Genetic analyses show that many sponge species in the Indo-Pacific are regionally unique
The Indo-Pacific is the largest marine biogeographical region on Earth and a global center of marine biodiversity. Nevertheless, there are gaps remaining in our understanding of the diversity, distribution, and endemism of ...
Phys.org / Extremely rare second-generation star discovered inside ancient relic dwarf galaxy
Discovered in the Pictor II dwarf galaxy, star PicII-503 has an extreme deficiency in iron—less than 1/40,000th of the sun. This signature makes it the clearest example of a star within a primordial system that preserves ...
Phys.org / ISS study identifies thresholds for muscle atrophy and fiber changes in reduced gravity
It's well known that spaceflight causes muscle atrophy and other biological changes in reduced gravity, and especially in near-zero gravity (microgravity) environments. However, the gravity threshold needed to maintain sufficient ...
Phys.org / Globular cluster NGC 5824 is embedded in a dark matter halo, study suggests
Using data from the Magellan Clay telescope and the Canada-France-Hawaii Telescope (CFHT), astronomers have investigated a galactic globular cluster known as NGC 5824. Results of the new study, available in a paper published ...
Phys.org / Bull sharks form social relationships with specific 'friends,' research reveals
Sharks are often viewed as solitary, but a new study—carried out on the Shark Reef Marine Reserve in Fiji—has found that rather than mixing at random, bull sharks have "active social preferences" and choose their social ...
Phys.org / Turning mosquitoes into flying vaccine carriers to protect against bat-borne viruses
Bats are reservoirs for several zoonotic viruses, such as Ebola and coronaviruses. These pathogens can spread to humans through direct contact with the flying mammals or their bodily fluids, or indirectly through contaminated ...
Phys.org / Do political social media ads influence the outcome of elections?
Social media platforms, such as Facebook, Instagram and X, are accessed daily by millions of people worldwide. In the weeks or months leading up to elections, many political parties use social media platforms as part of their ...
Phys.org / ChatGPT can provide original mathematical proofs, researchers show
VUB's Data Analytics Lab has published new results showing that it is possible to develop original mathematical proofs using commercial language models. In a paper posted to the arXiv preprint server, the researchers show ...
Phys.org / Not just spin—electron orbitals can provide new method for controlling magnetism
Research is actively underway to develop a "dream memory" that can reduce heat generation in smartphones and laptops while delivering faster performance and lower power consumption. Korean researchers propose a new possibility ...
Phys.org / Location of reforestation projects has greater effect on climate than number of trees planted, study shows
In the fight against the climate crisis, countries are pinning great hope in reforestation projects. In a new study, ETH Zurich researchers show that the location in which reforestation is taking place is usually more important ...
Phys.org / A galaxy next door is transforming, and astronomers can see it happening
The Small Magellanic Cloud (SMC) is one of the Milky Way's closest galactic neighbors—a small, gas-rich galaxy visible to the naked eye from the southern hemisphere, and bound to our galaxy by gravity, alongside its companion, ...
Phys.org / Ice satellite detects powerful geomagnetic storm with precision
It seems improbable that a satellite designed to monitor polar ice sheets and floating sea ice could accurately measure a disturbance in Earth's magnetic field. But that is just what ESA's CryoSat mission did earlier this ...
