First response should be chest compressions rather than preventing tongue swallowing', researchers suggestIt is the simple life-saving sequence taught in many a first aid lesson: when someone collapses, first check their airways, then breathing and finally circulation before starting chest compressions if needed.But experts have warned this approach to CPR could be increasing the risk of death for athletes experiencing a cardiac arrest.

While Gilmour Space's Eris rocket lasted only 14 seconds in the air above Bowen, nascent Australian space industry says failed orbit attempt is a launchpad for future success
Although the trends can be hard to perceive, we are making incredible progress on global poverty, health, longevity and climate changeDon't fret the future.A lot of people do, and for powerful reasons - we are facing enormous challenges unprecedented in human history, from climate change and nuclear war to engineered pandemics and malicious artificial intelligence. A 2017 survey showed that nearly four in 10 Americans think that climate change alone has a good chance of triggering humanity's extinction. But we seem largely blind to the many profound reasons for hope - and it's not entirely our fault. Continue reading...

Diagnosed with impaired depth perception as a child, Hampton has learned to read subtle cues from penalty takers and embrace goalie tacticsHannah Hampton had already saved one penalty in the shootout against Spain at Euro 2025 when Aitana Bonmati, the back-to-back winner of the women's Ballon d'Or, placed the ball on the spot and stepped back, taking a moment before the strike. Bonmati thumped the ball hard and left, but Hampton was there, arms outstretched, to block the shot with both hands.Better pens than the last time, let's be honest!" Hampton said after the match, a reference to the more painful shootout against Sweden in the quarter-final that went to sudden death before England prevailed. Hampton saved two penalties that time, too. Continue reading...

Skulls were collected from all over the world because of some academics' fascination with phrenology, the discredited belief that skull shape denoted intelligenceHundreds of skulls are neatly and closely placed, cheekbone to cheekbone, in tall, mahogany-framed glass cabinets. Most carry faded, peeling labels, some bear painted catalogue numbers; one has gold teeth; and the occasional one still carries its skin tissue. This is the University of Edinburgh's skull room".Many were voluntarily donated to the university; others came from executed Scottish murderers; some Indigenous people's skulls were brought to Scotland by military officers on expeditions or conquest missions. Several hundred were collected by supporters of the racist science of phrenology - the discredited belief that skull shape denoted intelligence and character. Continue reading...
We need to reckon honestly with science's past and present to avoid a grim futureScience is in crisis. Funding infrastructures for both basic and applied research are being systematically decimated, while in places of great power, science's influence on decision making is waning. Long-term and far-reaching studies are being shuttered, and thousands of scientists' livelihoods are uncertain, to say nothing of the incalculable casualties resulting from the abrupt removal of life-saving medical and environmental interventions. Understandably, the scientific community is working hard to weather this storm and restore funding to whatever extent possible.In times like these, it may be tempting to settle for the status quo of six months ago, wanting everything simply to go back to what it was (no doubt an improvement for science, compared with the present). But equally, such moments of crisis offer an opportunity to rebuild differently. As Arundhati Roy wrote about Covid-19 in April 2020, Historically, pandemics have forced humans to break with the past and imagine their world anew. This one is no different. It is a portal, a gateway between one world and the next." What could science look like, and what good could science bring, if we moved through the portal of the present moment into a different world?Ambika Kamath is trained as a behavioral ecologist and evolutionary biologist.

Researchers believe humans' closest relatives may have stored meat from their kills for months before eating itFor hungry Neanderthals, there was more on the menu than wild mammals, roasted pigeon, seafood and plants. Chemical signatures in the ancient bones point to a nutritious and somewhat inevitable side dish: handfuls of fresh maggots.The theory from US researchers undermines previous thinking that Neanderthals were hypercarnivores" who stood at the top of the food chain with cave lions, sabre-toothed tigers and other beasts that consumed impressive quantities of meat.

Technology is tricky. That's why we need to think more carefully about risks and follow a more cautious approachToday, so-called techno-optimists fill the ranks of Silicon Valley billionaires. They proclaim a bright future for humanity delivered by the rapid pursuit of technological advances.Of course, these techno-optimists are right that technology and science are unarguably among humanity's greatest assets, and hope for the future. But they go too far, because it is also true that technology always creates new problems even as it solves others - this is also something we've learned through science. As a result, naive faith in technology is a recipe for repeatedly achieving a short-term buzz while also incurring long-term costs. Getting the best out of technology requires a more cautious and balanced approach.Mark Buchanan is a physicist and science writer and the author of Ubiquity and Nexus: Small Worlds and the New Science of Networks Continue reading...

To find out what might be going on, Ian Sample hears from Prof Michael Snyder, the director of the Center for Genomics and Personalised Medicine at Stanford University School of Medicine, who explains what the drivers of these bursts of ageing could be, and how they might be counteractedScientists find humans age dramatically in two bursts - at 44, then 60Support the Guardian: theguardian.com/sciencepod Continue reading...
Pioneering radio astronomer whose work locating celestial objects led to a greater understanding of the universeSir Francis Graham-Smith, who has died aged 102, was the last of the generation that created modern radio astronomy, the branch of astronomy that studies the universe with radio waves, in the 1940s and 50s. His PhD thesis, on the first Cambridge radio survey, carried out between 1948 and 1950, with reasonably accurate positions for the brightest sources, paved the way to demonstrating that the majority of celestial radio sources are distant galaxies with massive black holes in their nuclei.Following the discovery of pulsars, pulsating radio sources associated with rapidly rotating neutron stars, in 1967 by Antony Hewish, Jocelyn Bell and others, Graham-Smith used the Jodrell Bank Mark I telescope to study pulsars in detail. He and Andrew Lyne wrote the definitive book on the subject, Pulsar Astronomy (1990). Continue reading...

Researchers believe huge volcanic eruptions, and the absence of plants, turned our planet into one giant snowballIt's hard to believe, but about 700m years ago it's thought that our planet completely froze over with little to no liquid ocean or lakes exposed to the atmosphere, even in the tropics. But what tipped Earth's climate into Snowball Earth" state? A new study suggests a cold climate and massive volcanic eruptions set the scene.The Franklin eruptions - about 720m years ago - spewed out vast amounts of fresh rock, stretching from what is now Alaska, through northern Canada to Greenland. Similarly large eruptions have happened at other times, but this one happened to coincide with an already cold climate. And combined with a lack of plants (they hadn't evolved yet) these eruptions exposed a huge carpet of fresh rock to intense weathering. Continue reading...

UK research has brought real hope to families suffering from one of the most common inherited disorders, with a breakthrough that's been years in the makingEight babies have been born free of a disease that canlead to terrible suffering and early death, thanks to pioneering scientists in the UK employing a form ofgenetic engineering that is banned in some countries, including the US and France. Ten years ago, when the government and regulators were consideringwhether to allow mitochondrial transfer technology, critics warned of Frankenstein meddling" that would lead to three-parent children. It's hard now to justify such hostility in the face of the painstaking work carried out by the scientific andmedical teams at Newcastle, resulting in these healthy babies and ecstatic families.Mitochondria, like tiny battery packs, supply energy to every cell of the body. Their DNA is handed down in the egg from mother to child. In rare instances, there are genetic mutations, which means the baby may develop mitochondrial disease. About one in 5,000 people is affected by it, making it one of the most common inherited disorders. As the cell batteries fail in various organs, the child can experience a range of symptoms, from muscle weakness to epilepsy, encephalopathy, blindness, hearing loss and diabetes. In severe cases, they die young.Do you have an opinion on the issues raised in this article?

Thought extinct in wild until three plants were found in 2002, Snowdonia hawkweed numbers have risen to sixOne of the rarest plants in the world is growing at a secret location on the edge of Eryri in north Wales.The Snowdonia hawkweed (Hieracium snowdoniense) is a small plant, barely reaching 30cm high, but with a brilliant golden yellow inflorescence that looks a bit like a dandelion, which it is closely related to. The Snowdonia hawkweed was first discovered only in 1880 at a remote hillside near Bethesda on the edge of Eryri, or Snowdonia, but in about 1950 the plant vanished, feared extinct after sheep grazed heavily in the area. And so the plant earned the unenviable title of the Welsh dodo. Continue reading...
