Phys.org / HETDEX opens massive Cosmic Noon dataset to scientists, novices and AI
The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX)—which recently completed the largest survey ever taken of the early universe—has released all of its immense, information-rich database to the public. Built from ...
Phys.org / 'BBQ sauce' phase may link little red dots to quasars
Everyone knows that finding the right sauce recipe can make or break a barbecue, but now astronomers are using BBQSORS (pronounced "barbecue sauce") as part of the recipe to explain quasars, some of the brightest objects ...
Phys.org / A new capability to detect chemical weapons involves two existing methods
In the aftermath of suspected chemical attacks, investigators from the Organization for the Prohibition of Chemical Weapons (OPCW) step in to collect chemical, environmental, and biomedical samples. Thorough forensic laboratory ...
Phys.org / Spider webs capture hidden fungal diversity in Thai rice fields
A new study published in the open-access Biodiversity Data Journal suggests that spider webs—particularly those incorporating environmental debris—can serve as natural, non-destructive collectors of fungal material in agricultural ...
Phys.org / Ultrafast laser shrinks to chip scale, potentially lowering costs for diagnostics and atomic clocks
Ultrafast lasers emit pulses lasting only a few hundred femtoseconds (quadrillionths of a second). These flashes of light power applications from precision micromachining to eye surgery to optical frequency combs, the Nobel ...
Phys.org / Tanzania's iconic heritage sites face damage from state-backed tourism
Assessment of four heritage sites in Tanzania finds that all are under threat from the institutions meant to steward them, prioritizing income from tourism over the sites' preservation and refusing to engage with community ...
Phys.org / How Jupiter may have redirected life's ingredients toward Earth 4.5 billion years ago
NASA-supported scientists have provided new information about how the early Earth may have acquired some elements necessary for the planet to become habitable. They also suggest a new role for Jupiter in the distribution ...
Phys.org / Plants boost carbon uptake through water efficiency, not heat adaptation, global analysis reveals
An international team of scientists has discovered that plants are not responding to global warming in the way researchers long assumed. Scientists have expected that ecosystems would keep pace with warming by rising the ...
Phys.org / Climate change may shift hailstorms toward Earth's poles—new study
Everyone has a storm story—whether it's that time you just escaped a downpour, or the hailstorm that wrote off your car. Even though hailstorms are relatively rare, they cause significant damage. Two new studies shed light ...
Phys.org / Ancient DNA offers hope for California's critically endangered black abalone
Black abalone once carpeted the rocky shores of California by the millions. The large, long-lived sea snails sustained Indigenous peoples along the coast for thousands of years, anchored a thriving 20th-century commercial ...
Phys.org / Interstellar object 3I/ATLAS reveals no technosignatures in seven-hour radio scan
Scientists at the SETI Institute recently searched for technological signals from 3I/ATLAS, the third interstellar object observed in our solar system. Using the Allen Telescope Array (ATA) at the Hat Creek Radio Observatory ...
Phys.org / Ancient cave lion genomes reveal a distinct lineage
A new study on multiple genomes from the extinct cave lion has discovered that it represented a highly distinct evolutionary lineage, which separated from modern lions more than a million years ago. The results also show ...
