The Sun is the most studied star in the universe, yet some of its most violent behaviour remains stubbornly out of reach. Solar flares, explosive eruptions that can disrupt satellites, knock out power grids and bathe astronauts in radiation release enormous bursts of X-rays that carry vital clues about what drives them. Now, a team of Japanese engineers has built the sharpest X-ray telescope ever to fly on a solar mission, and the technology it has pioneered could soon fit inside a satellite the size of a shoebox.

Thirty four years ago, a group of Cornell scientists looked at a remote Chilean mountaintop and imagined what might be built there one day. That day has arrived. The Fred Young Submillimeter Telescope has just opened its eyes on the universe from one of the most extreme observatory sites ever chosen, and the science it promises to deliver from the first moments after the Big Bang to the hidden nurseries of newborn stars.

A massive Swedish study shows that AI can spot people at higher risk of melanoma using routine health data. Advanced models significantly outperformed basic methods, identifying high-risk groups with striking accuracy. Some individuals flagged by the system had up to a 33% chance of developing melanoma within five years. This approach could pave the way for smarter, more targeted screening.

In a major breakthrough, scientists have observed electrons in graphene flowing like a nearly frictionless liquid, defying a core law of physics. This exotic quantum state not only reveals new fundamental behavior but could also unlock powerful future technologies.

In crowded environments, more robots don’t always mean faster results—in fact, too many can bring everything to a standstill. Harvard researchers discovered a surprising fix: adding a bit of randomness to how robots move can actually prevent gridlock and boost efficiency. By allowing robots to “wiggle” slightly instead of marching in straight lines, they can slip past each other and keep tasks flowing smoothly.

In 1937, Ettore Majorana asked a question nobody else was even thinking about: does a particle have to have a distinct antiparticle? For neutrinos — which carry no charge — the answer might be no. They might be their own antiparticles. Deep underground right now, experiments are watching atoms decay, waiting for the signal that would prove it. So far: nothing. But the case is not closed.

Rovers equipped with Radioisotope Power Systems (RPSs), aka. nuclear reactors, could effectively explore the craters in the Moon's southern polar region.

They are the most abundant particles in the universe, yet we barely know they exist. Neutrinos stream through everything, through walls, through planets and even through you…. in their billions every second, leaving no trace. We've known for decades that they have mass, but pinning down exactly how much has defeated physicists for years. Now, the most sensitive experiment ever built has pushed our knowledge to a new frontier, and what it found raises a profound question about why these ghostly particles are so extraordinarily light.

The lunar south pole is where humanity plans to build its first permanent outpost but we still don't fully understand what lies beneath the surface. A new study has used radar to peer below the ground in one of the Moon's most complex and battered regions and what it's finding raises important questions about the geological minefield that future astronauts will be navigating. Ancient impacts, frozen melt sheets, and billions of years of overlapping debris may complicate our plans more than we thought.

When a massive star explodes on the far side of the universe, the light from that explosion normally fades long before it reaches us. But occasionally, the universe conspires to help. A newly discovered supernova has been caught using the gravity of an entire galaxy as a natural magnifying glass, boosting its light by at least a hundred times and revealing a stellar death that would otherwise have been completely invisible. It is the most magnified supernova ever found, and it opens a remarkable new window onto the distant universe.

A planet-warming El Niño climate phase is now developing, and some models predict it could turn out to be the strongest on record

Around 900,000 years ago, an impactor slammed into modern-day Kazakhstan and excavated a crater about 14 km in diameter. It was the most recent hypervelocity impactor powerful enough to trigger a nuclear winter, but not an exinction. New research suggests the crater is almost twice as large, showing that the energy released by the impact was much greater than thought.

The protein craze is in full swing and beef consumption is on the rise, particularly in the US, where health agencies are promoting red meat as part of an optimum diet. So, how much beef should we really be eating, and how does it impact our well-being?

The gap between genetics and archaeology leaves us with an unclear picture of where the Neanderthals originated. Columnist Michael Marshall details a surprising new hypothesis that suggests they may have come from us

How do you portray momentum in space accurately? Columnist Chanda Prescod-Weinstein takes a look at the origins of our understanding of motion, which runs from Isaac Newton back to the Zhou dynasty a millennia ago

L-ergothioneine, an antioxidant found in certain mushrooms, is thought to neutralise damaging molecules in uterine cells that may contribute to period pain

Antibodies mistakenly attacking the brain are linked with conditions including schizophrenia, dementia and OCD, prompting a revolution in how we think about mental health conditions

A breakthrough experiment has shed new light on one of astrophysics’ biggest mysteries: the origin of rare proton-rich elements. For the first time, scientists directly measured a key reaction that creates selenium-74 using a rare isotope beam. The results sharpen models of how these elements form in supernova explosions, cutting uncertainty in half. But the findings also reveal gaps in current theories, hinting that the story isn’t complete yet.

The day when a quantum computer manages to break common encryption, or Q-Day, is fast approaching, and the world is not close to being ready
