Phys.org / Organic carbon detected in Bright Angel rock formation on Mars
In September 2025, NASA announced that its Perseverance rover had discovered a potential biosignature, which is a substance or structure that might have a biological origin. A new paper, published in Science Advances, unambiguously ...
Medical Xpress / Uneven cerebellum aging may partly explain why some older adults stay mentally sharp
Scientists may have discovered a new role for the cerebellum, the part of the brain that sits at the base of the skull. A new paper published in the journal Nature Neuroscience reports that different parts of the cerebellum ...
Phys.org / Horizon edge states gain finite description in string theory calculation
Modern physics theories highlight the key role of horizons—boundaries beyond which information cannot reach an observer—in a variety of cosmological and gravitational phenomena. Two renowned examples of these boundaries are ...
Phys.org / Human sacrifice in Inca Empire may have been driven by political motives, not religion
Three decades ago, researchers working atop the Llullaillaco volcano, located on the border between Argentina and Chile, discovered exceptionally well-preserved remains. The find included the mummified bodies of three children ...
Phys.org / Binary black hole signal probes event horizon region for first time
If, in space, no one can hear you scream, it seems that you can actually hear the sound of a crash when two black holes collide. Using the loudest gravitational wave ever heard, two Australian scientists and colleagues have ...
Phys.org / How ancient subduction zones helped create hotspots of mineral wealth
A study led by geoscientists at the University of Sydney has revealed why some ancient continental edges became fertile sites for major mineral deposits, while others with apparently similar geology did not.
Medical Xpress / Top supplements Americans use are shifting from multivitamins to targeted health fixes
Dietary supplements are an excellent way to fill gaps in our nutritional requirements. From vitamins and macronutrients to gut-health probiotics, dietary supplements have helped people address deficiencies. In recent years, ...
Phys.org / Ancient proteins hint at all-female Homo naledi burial site in Rising Star cave system
Scientists have extracted and analyzed the first-ever ancient proteins from the fossils of Homo naledi, revealing a potential all-female burial site. The study, published in the journal Cell, raises the possibility that South ...
Phys.org / Lavatory shaft reveals the cost of 17th‑century vanity in Germany
Four goose skulls were pulled from a former toilet shaft in Brandenburg, Germany, each of them riddled with strange holes. As it turns out, these holes were the telltale signs of fancy feathered crests, making them the first ...
Phys.org / Quantum squeezing sidesteps the limits on mechanical transducers
From detecting the ripples of colliding black holes to imaging individual chemical bonds, mechanical transducers have repeatedly transformed our understanding of the universe. So far, however, the sensitivity of these devices ...
Dialog / Miniature satellite tags reveal diving behavior of juvenile sea turtles
Until recently, researchers were unable to conduct satellite-tracking studies on juvenile turtles because of their small body sizes and immediate dispersal into the ocean, leaving this period of their lives enigmatic and ...
Medical Xpress / Exposure to bright evening light linked to higher risk of age-related eye disease
Every sunrise and sunset sends the body a signal, keeping the circadian clock running on a roughly 24-hour cycle. This clock evolved so organisms could adapt to Earth's daily rotation, syncing their biology to the pattern ...
