Astronomers have released more than three million new spectra in Data Release 20 from the Sloan Digital Sky Survey V, including the first SDSS-V optical observations from the Southern Hemisphere, revealing rare stars, glowing nebulae, X-ray sources, and supermassive black holes changing over time.^[1]

A magnitude 7.7 earthquake struck off Indonesia's Flores Island early Saturday, killing at least 47 people, damaging buildings, and triggering more than 230 aftershocks, with rescue teams still working to reach remote areas blocked by landslides.^[2]

A new analysis challenges a 60-year-old theory about why ants, bees, and wasps evolved complex societies, suggesting that haplodiploidy genetics alone cannot explain the evolution of eusociality and that other traits unique to these insects may be responsible.^[3]

Astronomers have discovered the first globular-cluster stellar stream ever observed outside the Milky Way, found in the ultra-diffuse galaxy UGC9050-Dw1, offering a new tool for mapping dark matter in distant galaxies.^[4]

New research published in Physical Review Letters shows that early-universe plasma may have prevented hypothetical dark photons from heating the cosmos, opening new experimental territory for the search for dark matter.^[5]

Researchers analyzing more than two decades of U.S. health data found that blood bicarbonate levels have risen approximately 7% since 1999 while calcium and phosphorus have declined, changes that closely track increasing atmospheric CO2 concentrations.^[6]

Scientists found that when dietary fiber is limited, gut microbes may begin consuming proteins from the protective mucus lining of the gut, while digestion-resistant plant proteins can help maintain healthy metabolite profiles.^[7]

Strontium isotope analysis of tooth enamel from 2,600-year-old Greek mass graves at Phaleron indicates that 64 of 66 shackled men buried there were local to the Attica region, similar to the wider burial population.^[8]

James Webb Space Telescope observations have revealed how Neptune's tiny moons tell the story of Triton's capture, with the largest moon comprising more than 99% of all satellite mass while orbiting retrograde compared to Neptune's rotation.^[9]

A new study in Nature Communications shows that trithorium clusters exhibit strong diamagnetism consistent with aromatic superatom behavior but display an unusual initial weak paramagnetic response, resolving conflicting interpretations of these materials.^[10]
