A naturally occurring compound found in foods such as wheat germ, mushrooms, and aged cheese may help older adults build stronger protection after vaccination. In a small pilot trial, researchers gave spermidine supplements to adults over 65 following their third COVID-19 vaccine dose. The biggest improvements appeared among people whose immune systems initially responded poorly, with higher antibody levels and stronger activity against several variants.

Dying Sun-like stars may not fade away quietly. As blobs of gas erupt unevenly from their swollen surfaces, each burst gives the star a tiny push in the opposite direction. Thousands of these random kicks could eventually break apart distant stellar pairs or, in rare cases, drive two stars into a violent collision.

A new theoretical study offers a possible explanation for how the Universe can grow more complex without violating the second law of thermodynamics. Using a quantum gravity framework called Gravity from Entropy, mathematician Ginestra Bianconi found that the Universe’s total entropy may rise as space expands, even while entropy within each unit of volume falls. That decline could leave room for galaxies, stars, planets, and life to form locally amid an overall increase in cosmic entropy.

Scientists have developed a fully human antibody that halted the growth and spread of aggressive prostate cancer in preclinical research. Although more testing is needed, the drug’s unusual mechanism could open the door to a safer new treatment for advanced cancer.

Google’s ‘Debug’ project in California and Florida aims to reduce mosquito numbers by releasing millions of sterilised malesIn the United States, Google’s (now Alphabet) Debug initiative has asked the federal government for permission to release up to 32 million sterilised male mosquitoes in California and Florida.Male mosquitoes don’t bite or carry disease. The hope is these millions of male mosquitoes will mate with disease-carrying females, the eggs won’t hatch and mosquito numbers will fall.

Scientists recorded slower reduction over past 20 years, but study finds this was ‘temporary rather than sustained’A previously recorded slowdown in Arctic sea ice decline has ended, according to a new study, with the largest year-to-year wintertime reduction ever recorded.In a study published last summer, researchers found that melting sea ice in the Arctic had slowed down over the past 20 years, with no statistically significant decline in its extent recorded between 2005 and 2024.

The answer to today’s puzzleEarlier today I set you a puzzle about keeping homes cool in a heatwave. Here it is again with the solution.Imagine a room with a set of curtains. When the Sun is shining, its energy comes through the windows where it is absorbed by the curtains. The curtains get hotter and hotter until they reach a temperature at which they are radiating as much heat as they absorb. The curtains radiate 50 per cent of this heat back towards the window, and 50 per cent of the heat int

Fifty years ago, NASA’s Viking 1 and 2 landers made the first successful landings on Mars, opening a new era in planetary exploration. Behind that achievement was a team at NASA’s Langley Research Center in Hampton, Virginia, whose steady leadership and technical expertise helped turn an ambitious idea into a mission that reshaped how we […]

“Touchdown, we have touchdown!” At 5:12 a.m. PDT, July 20, 1976, mission controllers at NASA’s Jet Propulsion Laboratory erupted in cheers as they learned that the Viking 1 lander had survived its descent through the thin Martian atmosphere. Forty minutes later, the lander’s first image began to appear on their monitors, slowly forming line by […]

Scientists have discovered a hidden warning sign of skin damage that appears before collagen fibers visibly thin, break, or lose their connections. Using advanced light-based techniques, the team found that collagen’s carefully organized molecular “handedness” can collapse even while the tissue still appears structurally intact and contains the same amount of collagen. This suggests that skin may begin deteriorating at a much deeper level long before conventional imaging can detect a problem.

Two elephant-sized South American sauropods were unusually well built for standing on their hind legs. Digital tests showed that their robust femurs handled the enormous forces better than those of larger species, especially while the dinosaurs were young. The upright pose may have helped them reach treetops, frighten predators, or impress potential mates.

Elon Musk is trying to own it, competing powers are trying to fight in it and nobody seems to be regulating it. So who does space really belong to?The last time I saw Laura Grego was in a tent in a baking field on the Welsh borders in May. The conversation on stage ranged from the dangers of space debris to how the law of the sea might pertain to outer space; from our sense of the sacred to our interplanetary futures. At one point Grego, a physicist, said intently, “People have to be aware of wh

Oxygen is disappearing from oceans, lakes, rivers, and coastal waters at an alarming rate, threatening aquatic life and weakening the natural processes that help regulate Earth’s climate. Scientists warn that this widespread deoxygenation is closely connected to other major planetary threats, including warming, pollution, biodiversity loss, and ocean acidification.

Researchers have uncovered a surprising culprit behind sleep loss in Alzheimer’s disease: the brain’s own immune cells. In mice with amyloid plaques, overactive microglia triggered inflammation that kept the brain from getting enough deep, restorative sleep. Temporarily removing most of these cells restored more than two hours of sleep per day, even though the plaques remained unchanged.

A quantum problem once described as impossible for classical computers has now been solved using relatively modest hardware. Researchers used tensor networks to compress the overwhelming wave function created by hundreds of entangled qubits, allowing some calculations to run on a laptop. Their results matched both theoretical predictions and simulations performed with a quantum computer. The method could open new paths for exploring quantum dynamics and materials.
