Science news: space, biology, climate, medicine and the research changing how we live.
Oregon State University researchers drilling in Antarctica's Allan Hills found that CO2 levels three million years ago were 250 ppm — yet temperatures were far warmer than expected, suggesting standard climate models badly underestimate Earth's sensitivity.
Japan's Fugaku computer resolved stellar magnetic fields at 5.4 billion grid points, revealing that the fields prevent sun-like stars from ever switching to solid-body rotation — rewriting solar physics textbooks.
Astronomers using Chilean telescopes found at least four planets around GJ 887, with the outermost sitting in the habitable zone — only the second such world known within 10 light-years of Earth.
Durham University researchers have dealt a serious blow to the Younger Dryas Impact Hypothesis, showing that the mysterious platinum concentration in ancient Greenland ice appeared 45 years after the cooling began — and came from Icelandic volcanic eruptions, not space.
Research from the University of Colorado Boulder shows the widely used sweetener can disrupt brain blood vessel cells and reduce the body's ability to break down clots at typical consumption levels.
A new machine learning framework called THOR — developed by Los Alamos National Laboratory — cracks the 'configurational integral' problem that has stymied materials scientists for a century, enabling lightning-fast predictions of how atoms behave under extreme pressure.
Scientists develop targeted brain treatment that mimics morphine's benefits while avoiding addiction risks, using AI to map precise pain circuits.
The World Meteorological Organization's annual State of the Global Climate report found 2025 averaged 1.44°C above pre-industrial levels — and that ocean heat content, sea level rise, and ice loss all hit new records for the fourth consecutive year.
A new MMWR study identified 233 deaths and 538 hospitalizations linked to kratom in 2025 alone, driven by concentrated 7-hydroxymitragynine products that bind opioid receptors 13 times more powerfully than morphine.
Appearing in nearly every deep-field image since Webb launched, hundreds of mysterious luminous objects in the early universe remain unexplained despite hundreds of scientific studies — and may force a rethink of how the first black holes formed.
The Chinese manufacturer's NREL-certified result breaks through the Shockley-Queisser ceiling that no silicon-only cell can ever surpass — delivering 45% more power per unit of sunlight than today's commercial panels.
Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen are days from liftoff on a 10-day, 1.3-million-mile mission that will send the first woman and first Black astronaut beyond low Earth orbit, surpassing Apollo 13's record for the greatest distance from Earth.
Scientists at GOSH and UCL grew a functional food pipe from donor scaffolding and the recipient's own stem cells, successfully replacing the organ in eight pigs without immunosuppression — a breakthrough aimed at children born without a complete oesophagus.
Chemists at Kyushu University and University of Mainz used a molybdenum-based spin-flip metal complex to drive singlet fission in tetracene, converting one photon into two usable energy packets and surpassing the Shockley-Queisser limit.
University of Colorado Boulder researchers found that erythritol — used in diet drinks, keto foods, and 'sugar-free' products — reduces blood vessels' ability to dilate, increases clotting risk, and generates free radicals in brain vascular cells.
A new species named Masripithecus moghraensis is the closest known relative to the ancestor of all living apes and humans — and its location in northern Africa suggests scientists have been looking in the wrong region for decades.
University of York scientists found that a gene producing the alkaloid securinine looks nothing like other plant genes — it looks bacterial, suggesting plants borrowed genetic machinery from microbes millions of years ago.
A Northwestern University-led team mapped over 140,000 chromatin loops across multiple cell types, showing that the physical folding of DNA — not just its sequence — determines which genes are active.
Researchers identified the biological pathway that links immune responses in the gut to appetite suppression in the brain during parasitic infections.
A UT Austin study of 13,000 microbial genomes reveals that Asgard archaea — our most ancient ancestors — can metabolize oxygen, resolving the mystery of how two incompatible life forms merged to create eukaryotes.
A UT Austin study using helium-3 to refine ancient sediment timelines reveals that biological recovery from the Chicxulub impact was orders of magnitude faster than previously estimated.
Researchers develop breakthrough yeast-based supplement that provides essential nutrients missing from modern pollen sources, offering hope for struggling bee populations facing climate change and habitat loss.
A system built by UBC, Sakana AI, and Oxford generated its own ideas, ran experiments, wrote manuscripts, and passed peer review at ICLR — the first AI to navigate the complete scientific process independently.
The Imaging X-ray Polarimetry Explorer spacecraft revealed new detail in the remains of a stellar explosion first recorded by Chinese astronomers in 185 AD, using polarized X-rays to map its magnetic fields.
The tech giant moved its internal post-quantum cryptography deadline six years ahead of the federal government's, warning that 'store now, decrypt later' attacks may already be underway.
Using the Very Large Telescope's upgraded GRAVITY+ instrument, scientists have directly confirmed a second protoplanet in what researchers call 'the best look into our own past.'
Cornell's MOTE device uses laser beams to power and communicate with the world's tiniest wireless neural implant, opening a new path for brain-computer interfaces that require no wires or batteries.
The star system WISPIT 2, just 5 million years old, becomes only the second known system where multiple planets have been directly observed forming simultaneously — offering an unprecedented planetary science laboratory.
With the SLS rocket on the pad at Kennedy Space Center, Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen are five days from a historic April 1 launch around the Moon.
International team races to build massive genomic database of European marine worms as species vanish faster than researchers can identify them.
