A pioneering study has provided unprecedented insights into the immune response following pig-to-human kidney xenotransplantation.1 The findings, presented today at the ESOT Congress 2025, mark a significant step forward in overcoming the biggest challenge in xenotransplantation: rejection by the human immune system. Using cutting-edge spatial molecular imaging, researchers mapped how human immune cells interact with […]

Previously described as playing astronomical ‘spot the difference,’ Kilonova Seekers asks the public to compare the latest images of a section of night sky to an image of the same section of space taken on previous nights. Their goal – to spot new stars or significant changes in light intensity that may indicate that something […]

A new study from scientists at the Buck Institute for Research on Aging has revealed a surprising player in the battle against Alzheimer’s disease and other forms of dementia: brain sugar metabolism. Published in Nature Metabolism, the research uncovers how breaking down glycogen — a stored form of glucose — in neurons may protect the […]

Spinal cord injuries are currently incurable with devastating effects on people’s lives, but now a trial at Waipapa Taumata Rau, University of Auckland offers hope for an effective treatment. Spinal cord injuries shatter the signal between the brain and body, often resulting in a loss of function.”Unlike a cut on the skin, which typically heals […]

Astronomers have uncovered a vast cloud of energetic particles — a ‘mini halo’ — surrounding one of the most distant galaxy clusters ever observed, marking a major step forward in understanding the hidden forces that shape the cosmos. The mini-halo is at a distance so great that it takes light 10 billion years to reach […]

Parts of New Orleans and its surrounding wetlands are gradually sinking, and while most of the city remains stable, a new study from Tulane University researchers suggests that sections of the region’s $15 billion post-Katrina flood protection system may need regular upgrades to outpace long-term land subsidence. The study, published in Science Advances, used satellite […]

Ōtākou Whakaihu Waka scientists have discovered that it takes mere minutes for a species of sex-changing fish to develop dominant behavior after a change in the pecking order. The new study led by the Department of Anatomy and published on Proceedings of the Royal Society B, examines the New Zealand spotty, or paketi, a fish […]

The central estimate of the remaining carbon budget for 1.5°C is 130 billion tonnes of carbon dioxide (CO2) (from the beginning of 2025). This would be exhausted in a little more than three years at current levels of CO2 emissions, according to the latest Indicators of Global Climate Change study published today in the journal […]

For 540 million years, the ebb and flow in the strength of Earth’s magnetic field has correlated with fluctuations in atmospheric oxygen, according to a newly released analysis by NASA scientists. The research suggests that processes deep inside the Earth might influence habitability on the planet’s surface. Earth’s magnetic field arises from the flow of […]

An interdisciplinary team of experts in green chemistry, engineering and physics at Flinders University in Australia has developed a safer and more sustainable approach to extract and recover gold from ore and electronic waste. Explained in the leading journal Nature Sustainability, the gold-extraction technique promises to reduce levels of toxic waste from mining and shows […]

Cats prefer to sleep on their left side. This is the conclusion drawn by an international research team that analyzed several hundred YouTube videos of sleeping cats. The researchers see this bias as an evolutionary advantage because it favors hunting and escape behavior after waking up. The team from the University of Bari Aldo Moro […]

A new study from the Cellular Ageing and Senescence laboratory at Queen Mary University of London’s Cenfre for Molecular Cell Biology, reveals how caffeine — the world’s most popular neuroactive compound — might do more than just wake you up. The study in the journal Microbial Cell shows how caffeine could play a role in slowing […]

Inhabiting Mars has long been a futuristic fantasy fueled by science fiction. However, successful landings on our neighboring planet over the past half-century have made this seemingly far-fetched idea increasingly plausible. But don’t start packing just yet. First, we must figure out how to build structures millions of miles from Earth. Sending rockets carrying massive […]

Quantum computers can solve extraordinarily complex problems, unlocking new possibilities in fields such as drug development, encryption, AI, and logistics. Now, researchers at Chalmers University of Technology in Sweden have developed a highly efficient amplifier that activates only when reading information from qubits. Thanks to its smart design, it consumes just one-tenth of the power […]

Years after wildfires burn forests and watersheds, the contaminants left behind continue to poison rivers and streams across the Western U.S. — much longer than scientists estimated. A new study, published on June 23 in Nature Communications Earth & Environment, analyzed water quality in more than 500 watersheds across the Western U.S., and is the first […]

The chemical reaction to produce hydrogen from water is several times more effective when using a combination of new materials in three layers, according to researchers at Linköping University in Sweden. Hydrogen produced from water is a promising renewable energy source – especially if the hydrogen is produced using sunlight. The production of new petrol […]

A single pellet of recycled plastic can contain over 80 different chemicals. A new study with researchers from University of Gothenburg and Leipzig shows that recycled polyethylene plastic can leach chemicals into water causing impacts in the hormone systems and lipid metabolism of zebrafish larvae. The plastic pollution crisis has reached global levels, threatening both […]

Understanding how the universe transitioned from darkness to light with the formation of the first stars and galaxies is a key turning point in the universe’s development, known as the Cosmic Dawn. However, even with the most powerful telescopes, we can’t directly observe these earliest stars, so determining their properties is one of the biggest […]

A team of researchers at Rice University have discovered a surprisingly simple method for vastly improving the stability of electrochemical devices that convert carbon dioxide into useful fuels and chemicals, and it involves nothing more than sending the CO2 through an acid bubbler. Their study, published in Science, addresses a major bottleneck in the performance […]

Scientists at the USC Leonard Davis School of Gerontology have discovered a key connection between high levels of iron in the brain and increased cell damage in people who have both Down syndrome and Alzheimer’s disease. In the study, researchers found that the brains of people diagnosed with Down syndrome and Alzheimer’s disease (DSAD) had […]

The idea seems futuristic: At ETH Zurich, various disciplines are working together to combine conventional materials with bacteria, algae and fungi. The common goal: to create living materials that acquire useful properties thanks to the metabolism of microorganisms — “such as the ability to bind CO2 from the air by means of photosynthesis,” says Mark […]
