Bronze instrument or carnyx dug up in Norfolk in area inhabited by Celtic tribe led by warrior who fought Romans

An “extraordinary” iron age war trumpet that may have links to the Celtic tribe led by Boudicca in the period they were battling the invading Roman army has been discovered by archaeologists in Norfolk.

The bronze trumpet or carnyx is only the third ever found in Britain, and the most complete example discovered anywhere in the world. Fashioned in the shape of a snarling wild animal, the object would have been mounted on a long mouthpiece high above the heads of warriors, allowing it to be sounded to intimidate the enemy in battle.

La mission Solar Orbiter marque un peu plus l’histoire de l’observation astronomique. Des scientifiques ont en effet réussi à suivre pendant 94 jours consécutifs une région solaire exceptionnellement active, à l’origine de la plus violente tempête géomagnétique observée depuis plus de vingt ans sur Terre. Une région solaire …

Reflecting a small fraction of incoming sunlight to reduce global heating is not a new idea. It is time to safely experiment

The world is warming fast – and our options to avoid catastrophic harm are narrowing. 2024 was the first full year more than 1.5C hotter than the 19th-century average. Emissions are still rising, with fossil fuel use expected to hit a new high in 2025. Permanent carbon removal technologies – often cited as a fix – are removing just tens of thousands of tonnes annually, almost nothing relative to the 5-10bn tonnes needed. Cutting emissions and scaling carbon removal remain essential. But they may not be enough.

As suffering grows and ecosystems unravel, more people will ask: is there anything we can do to prevent these harms? The idea of reflecting a small fraction of incoming sunlight to reduce warming is not a new idea. In 1965, Lyndon B Johnson’s science advisers proposed it as the only way to cool the planet. Earth already reflects about 30% of incoming sunlight; raising that fraction slightly – say, to 31% – could strengthen the planet’s natural heat shield. But how?

They can hurt more than broken bones or pancreatitis. But with the right drugs and therapies, relief is possible from this debilitating and often misunderstood condition

It was a dreary Monday morning in September 2016, and I was working as a teacher, trying to settle a new year 7 class, when a sharp pain bloomed behind my right eye. It was followed by quick jolts, like electric shocks. As each class came and went, the pain eased and then returned with greater intensity. Four times that day I left a teaching assistant with worksheets and ran to the school bathroom to douse my face with cold water. I took ibuprofen, paracetamol, aspirin, but the pain remained unbearable.

The headaches appeared repeatedly that autumn, and again in spring, and soon formed an annual pattern. September and October were the worst, then February and March. I could predict the routine: aura in the shower, early twinges on the train, full-blown agony in class by 9.30am. In late 2019, a GP finally referred me to a neurologist and I was diagnosed with cluster headaches.

Senior insider says ‘limbo’ at the Defence Science and Technology Laboratory has hit morale and disrupted vital research

A shake-up of the government’s defence science powerhouse at Porton Down has severely damaged morale and harmed work on critical science that supports national security, a senior whistleblower has told the Guardian.

The whistleblower said they were raising concerns in the public interest that the Defence Science and Technology Laboratory (DSTL), based largely at Porton Down in Wiltshire, had been left in a paralysing limbo because of the changes.

There’s nothing more uplifting than hearing about a world-shaking, life-enhancing new development. But science shouldn’t overlook the small stuff, or stop looking for new species of cute, fluffy mammals …

People who greet the new year with hope, ambitious plans and optimised gut microbiomes might be obnoxiously apparent at the moment, but we all know they’re a minority. Most of us lurched into 2026 catastrophically depleted and grey-faced, juggling deep Lemsip dependency with a deeper overdraft and a sense of ever-deepening global geopolitical foreboding. There is, however, one thing that fills me with buoyant optimism now and always: science. I don’t understand it, but I’m delighted it’s out there, making things better.

I was booted out of my leaden year-end listlessness by The Atlantic’s list of 55 Facts That Blew Our Minds in 2025. Did you know, for example, that scientists at UC Berkeley created a new colour? (It’s called “olo” and it’s sort of teal.) Or that doctors treated a baby with a rare genetic disorder with custom gene editing? There were more wonders in the Smithsonian’s list of last year’s fascinating scientific discoveries: ichthyosaurs, extinct marine reptiles, had “stealth flippers”, snails can regrow eyes within a month, and “flamingos form tornado-like vortices as they probe for prey”, which is pure poetry (it looks pretty cool too, I watched one do it on YouTube). Still on an animal theme, entomologists discovered a “bone collector” caterpillar that conceals itself in the body parts of its prey (I’m sure he’s lovely when you get to know him). 2025 was also the year science made oyster mushrooms play keyboards (sort of), astronomers discovered more than 100 moons in our solar system and medical researchers created replica womb lining and made astonishing progress towards lab-grown teeth.

Raise an eyebrow for World Logic Day

All days of the year host an annual celebration.

January 14 is a day of the year.

Psychologist Chris Moore saw first-hand how powerful and complex an emotion it is

Fuelled by the relief of having finished end-of-year exams, the pleasure of a warm late spring evening and quite a lot of alcohol, the house party was one of those that should have been remembered for all the right reasons. At some point, later in the night, Chris Moore and three friends were ready to leave. The party was some way out of town – Cambridge – and too far to walk, and, anyway, there was a car, temptingly, in the driveway, its keys in the ignition.

Somebody – Moore can’t remember who – suggested they drive back, and with the recklessness of youth and too much beer, they all got in. “I ended up in the front passenger seat and fell asleep,” he says. He came to, being taken out of the car by paramedics, then sitting by the side of the road, his face streaming with blood, surrounded by the lights of the emergency services. They had been in an accident, and Moore had hit the windscreen, asleep, and had deep lacerations on his forehead. He was the only one of the four who had been injured. What he didn’t know until the next day, in hospital after surgery, was that they had driven into a cyclist and killed him.
