An unusual flickering of a young F-type star called Gaia20ehk and an expanding cloud of dust around it suggest that a catastrophic planetary crash unfolded in real time, offering a rare glimpse of the violent processes that can shape young planetary systems.

New measurements show that the DART impact in 2022 not only shortened the orbit of the moonlet Dimorphos around its parent asteroid, Didymos, but also subtly shifted the entire binary system’s path around the Sun. This artist’s illustration shows the ejection of a cloud of debris after NASA’s DART spacecraft collided with the asteroid Dimorphos. Image credit: ESO / M. Kornmesser. When NASA’s...
Ancient DNA from brightly colored feathers found in Peru shows that at least four distinct species of Amazonian parrots — the scarlet macaw (Ara macao), the blue-and-yellow macaw (Ara ararauna), the red-and-green macaw (Ara chloropterus) and mealy amazon (Amazona farinosa) — were transported alive over the Andes centuries before the Inca Empire, evidence of sophisticated long-distance...
Fossil jaws of the ancient monkey species Stirtonia victoriae from the La Victoria Formation in Colombia suggest that a shift toward leaf-eating allowed early primates in South America to grow larger and occupy new ecological niches. The discovery may also hint at when the lineage developed the anatomical features that later produced the powerful howls of today’s howler monkeys. The mantled howler...
In a new study led by University of British Columbia Ph.D. student Hannah Griebling, raccoons (Procyon lotor) continued manipulating complex puzzle boxes long after retrieving the only marshmallow reward, suggesting the animals seek information for its own sake — a behavior that may underpin their urban success. Multiaccess puzzle box with easy (a), medium (b) and hard (c) solutions. Image...
Astrophysicists from the University of Illinois and the University of Chicago have developed an innovative method to measure the Hubble constant — the rate at which the Universe is expanding — using the subtle background hum of gravitational waves. As gravitational-wave detectors become more sensitive in the coming years, this approach could reshape our understanding of cosmic history...
In a randomized clinical trial of older adults, researchers found that taking multivitamins for two years modestly slowed epigenetic markers of aging — equivalent to roughly four months less biological aging compared with a placebo. Li et al. evaluated the two-year effect of daily multivitamin-multimineral supplements and cocoa extract (500 mg cocoa flavanols per day, including 80 mg epicatechin)...

New orbital data reveal that the most recently active volcanic systems on Mars weren’t simple one-off blasts into space; instead, long-lived magmatic plumbing beneath Pavonis Mons, one of the Red Planet’s largest volcanoes, reshaped lava flows over time, with distinct eruptive phases and evolving chemical signatures, offering fresh insights into the planet’s inner dynamics and how rocky planets...
