Deviare un asteroide con l'atomica: il vero limite è il tempo
Nuove simulazioni suggeriscono che un ordigno nucleare potrebbe deviare un asteroide, ma solo con un anticipo sufficiente. Il precedente della missione DART della NASA del 2022 apre la strada.
Uno sbadiglio prima di nascere: la relazione comincia nel grembo, secondo Vittorio Gallese
Uno studio dell'Università di Parma su Current Biology mostra che lo sbadiglio fetale aumenta dopo quello materno. Il neuroscienziato Vittorio Gallese ne trae una riflessione sulla relazione come condizione originaria della vita umana.
Antonelli, il campione del mondo che non ha ancora la corona: Mercedes ad Austin ingaggia un astronauta Nasa
Kimi Antonelli domina la stagione di Formula 1 e Mercedes lo affianca all'astronauta Reid Wiseman ad Austin; Russell ne riconosce il vantaggio tecnico e stilistico.
SUS detecta HPV de alto risco em 9,9 mil amostras e expande teste que identifica o vírus antes do câncer
O SUS detectou HPV de alto risco em 9.904 de 93 mil amostras de DNA-HPV processadas em 2026, com o exame já disponível em 26 das 27 unidades da federação.
Giant Asteroid to Pass Closer Than Some Satellites in About 900 Days
Forbes reports a large asteroid is projected to pass nearer to Earth than some satellites in roughly 900 days. The headline gives no detail on its size, exact approach distance, or margin of uncertainty.
Ancient DNA Shows Ice Age Europeans Maintained Long-Distance Connections Across the Continent
Ancient DNA from a French cave indicates Ice Age Europeans maintained east-west connections across long distances. Multiple outlets report the same findings.
Ukraine : trêve humanitaire annoncée à Oleshky, Starlink toujours défaillant
Melania Trump affirme avoir obtenu une trêve entre Russes et Ukrainiens à Olechky, ville en crise humanitaire. Les titres ne précisent ni la durée ni les modalités de ce cessez-le-feu.
New Protein SPRIZ Acts as a Molecular Pillar That Sets the Width of Mitochondrial Membrane Gaps
University of Ottawa researchers identified SPRIZ, a protein that acts as a molecular pillar setting the intermembrane space width in mitochondria, with implications for energy disorders and Parkinson's disease.
Fewer Nephrologists, Higher Kidney Disease Deaths: A Growing Gap Along the US-Mexico Border
A study of CDC data finds chronic kidney disease mortality in US-Mexico border counties rose faster than elsewhere from 1999 to 2022, alongside lower nephrologist availability.
Spinal Astrocyte Protein GPR177 Drives Neuropathic Pain Through C3/C3aR Signaling in Rats
A rat study finds spinal astrocytic GPR177 contributes to neuropathic pain by activating the C3/C3aR complement pathway, and silencing it or blocking the pathway reduces hypersensitivity.
Common Kidney Tests Miss Much of Chronic Kidney Disease in Cancer Patients, Study Finds
A study of 1,200 adults with solid tumors found creatinine-based kidney estimates miss many chronic kidney disease cases, risking inaccurate chemotherapy dosing. Findings are set for ASN Kidney Week 2026.
Shared Meiosis Proteins Take On Different Roles Across Animals, Stowers Study Finds
A Stowers Institute study in Science Advances finds meiosis proteins shared between sea anemones and humans often perform different roles, showing evolutionary flexibility in reproductive cell division.
Perseverance Passes Opportunity's Mars Distance Record, Driving Mostly on Its Own Autonomy
NASA's Perseverance rover surpassed Opportunity's record for the farthest distance driven on another world, covering over 45 km on Mars with mostly autonomous navigation.

Not All White Dwarfs Are White: Atmospheric Chemistry Can Tint Some Pink, Yellow, or Green
A University of Warwick-led study finds a small share of white dwarfs, shaped by dense atmospheres and trace elements, appear pink, yellow, or green rather than pure white.
‘Treble Clef’ Radio Glow Reveals Hidden Colliding Galaxy Cluster Behind the Milky Way
Astronomers identified the musical-note-shaped radio source VLSS J0318.9+5755 as a revived radio phoenix: ancient black hole plasma reenergized by a colliding galaxy cluster about 1.5 billion light-years away.
Researchers Identify 'Circadian' Subtype of Depression Linked to Body Clock Disruption
Australian researchers, including University of Sydney scientists, identified a new 'circadian' subtype of depression tied to body clock disruption that may respond poorly to standard antidepressants.
Stress, Sleep, Gut Health and Insulin: The Hidden Factors Shaping Your Metabolism
EatingWell outlines stress, sleep, gut health and insulin sensitivity as overlooked factors shaping metabolism, drawing on registered dietitian commentary. The piece is general wellness guidance rather than reporting on new research.
Thick Tumor Fluid May Make Glioblastoma Cells Smaller, More Flexible and Better at Invading Tissue
Chinese researchers found that prolonged exposure to viscous fluid makes glioblastoma cells smaller, more flexible, and more invasive, with some changes persisting after exposure ends.
NASA Invokes Apollo Playbook to Build Moon Base, Targets Astronaut Landing by 2028
NASA says it is accelerating Artemis, with an orbital docking test next summer and a first moon landing by astronauts since Apollo targeted for 2028.
NASA Weighs Meteor Strike Risks as It Plans a Permanent Moon Base by 2032
