If you’ve ever tried to lose weight, you’ve probably been told that cooking your own meals is the way to go. This has been backed up by a recent study, which found that people who ate home-cooked, minimally processed foods lost twice the weight compared to those who ate mainly ultra-processed, ready-made foods. The recent study, which was published in …

The asteroid Ryugu is an echo from the deep, distant past. Two tiny grains of the rock, delivered to Earth in 2020 by the famous Hayabusa2 mission, contain minerals older than any found on our planet. One grain comes from the asteroid’s surface, the other from within. Both are incredible archives of our early Solar System and the chemical reactions …

Adhering to a Mediterranean diet has been found to reduce the risk of Alzheimer’s disease even among individuals who are genetically predisposed to developing the neurodegenerative condition, according to a study by researchers in the US. Deriving its name from the region where it’s popular, the diet prioritizes fruit and vegetables, as well as olive oil, fish, nuts, and whole …

It’s no secret that excessive alcohol consumption damages the liver, but a new study reveals a previously unknown vicious cycle that makes that damage worse. Chronic alcohol use makes it easier for bacteria to leak out of the gut and migrate to the liver, causing further harm. The new study, led by scientists at the University of California San Diego, …

Identifying early signs of Alzheimer’s gives the best chance of slowing its progression, with researchers previously finding clues of the disease in a person’s speech and breathing, and in gut bacteria. Now a new study says a dwindling sense of smell may be one of the earliest indicators of the condition, arriving even before cognitive impairments. Related: 5 Early, Speech-Related …

A tiny blob of red light spotted at the beginning of the Universe could represent the first direct evidence for a supermassive black hole formation pathway. In a dazzling new paper, a large international team led by astrophysicist Ignas Juodžbalis of the University of Cambridge in the UK has directly measured the mass of one of the mysterious ‘Little Red …

We already knew that interstellar comet 3I/ATLAS was different from the other two interstellar objects known to have traversed the Solar System, but a slew of new observations suggest it may be even weirder than the weirder that it was. NASA and ESA instruments Hubble, SPHEREx, JWST, and TESS have all captured the object as it makes its way towards …

Scientists peering into the very heart of hearts of the planet Mars have found a deeply unexpected structure. There, at the innermost core of the planet, InSight seismic data reveals a solid mass about 600 kilometers (373 miles) across. This is not just in contrast to previous findings that the core is squishy all the way through – it doesn’t …

Millions of people worldwide take beta blockers to reduce the risk of cardiovascular problems, especially after a heart attack. But two new studies suggest that for many patients, these drugs may no longer be helpful – and in some cases, they could even be harmful. Beta blockers work to lower heart rate and blood pressure, reducing the oxygen demands of …

On 7 to 8 September 2025, a chance alignment of Earth, the Moon, and the Sun will see a good swathe of our planet bathed in the eerie red glow of a total lunar eclipse. It will be the longest total lunar eclipse since 2022, with a totality that lingers around 1 hour and 22 minutes, during which time Earth’s …
