The new dark galaxy candidate is dominated by dark matter and nearly devoid of light. Named Candidate Dark Galaxy-2 (CDG-2), the object consists of four globular clusters and belongs to the Perseus galaxy cluster. The discovery of CDG-2 challenges astronomers’ understanding of how galaxies form and evolve in the cosmic web, offering a new window into the Universe’s most elusive substance, dark...
In a paper to be published in the Planetary Science Journal, scientists from SETI Institute, Southwest Research Institute, Caltech and the Observatoire de Paris argue that two Saturnian moons, Titan and Hyperion, are not primordial worlds, but the result of a dramatic merger between two ancient moons. The findings could rewrite theories about how Titan’s thick atmosphere emerged and may even help...
A tiny copper-alloy object long dismissed as a simple awl has been reclassified as the earliest known rotary metal drill from ancient Egypt. Original photograph of the Badari drill published in 1927 by Guy Brunton (left) and the actual artifact. Image credit: Martin Odler & Jiří Kmošek, doi: 10.1553/AEundL35s289. The ancient drill is only 6.3 cm (2.5 inches) long and weighs about 1.5 grams. Dating...
For decades, depictions of Triceratops and its kin have been driven by bone alone. Now, paleontologists in Japan have mapped the soft-tissue anatomy of these horned dinosaurs, revealing unexpected structures that may explain how they regulated temperature and breathed. Triceratops’ nasal cavity. Image credit: K. Sakane. Horned dinosaurs (Ceratopsia), including the iconic Triceratops, were among...
Scientists have isolated a new strain of the Psychrobacter cryohalolentis species from 5,000-year-old ice from Scarisoara Ice Cave in Romania. Remarkably, the strain — labeled SC65A.3 — shows resistance to 10 widely used antibiotics, including drugs typically reserved for severe infections such as tuberculosis and urinary tract infections. Isolated colonies of Psychrobacter SC65A.3 on...
Physicists at the University of Massachusetts Amherst argue that an ultra-high-energy neutrino detected by the KM3NeT experiment could be the signature of an explosion of a ‘quasi-extremal primordial black hole,’ pointing toward new physics beyond the Standard Model. The KM3NeT experiment has recently observed a neutrino with an energy around 100 PeV, and IceCube has detected five neutrinos with...

Between 73,000 and 20,000 years ago (Late Pleistocene), the Japanese Archipelago was inhabited by cave lions (Panthera spelaea), according to a new genetic and proteomic analysis of fossilized felid remains previously attributed to tigers (Panthera tigris). Cave lions painted in the Chauvet Cave, France. Lions and tigers were widespread apex predators during the Late Pleistocene and integral components...
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...
Keratin composites enable animals to hike with hooves, fly with feathers, and sense with skin. Mammalian whiskers are elongated keratin rods attached to tactile skin structures that extend the animal’s sensory volume. In a new study, scientists at the Max Planck Institute for Intelligent Systems aimed to characterize the geometry, porosity, and stiffness of Asian elephant (Elephas maximus) whiskers. Schulz...
