Oral medications are in development to provide alternative to injectables such as Wegovy that must be kept in fridgeNewly developed weight loss pills could have a big impact on tackling obesity and diabetes in low- and middle-income countries, experts have said.Weight loss jabs such as Wegovy and Mounjaro, that contain the drugs semaglutide and tirzepatide respectively, have become popular in countries including the UK after trials showed they can help people lose more than 10% of their body weight. Medications containing semaglutide and tirzepatide can also be used to help control diabetes. Continue reading...
Maintaining a positive mood and eating more fruit may also help lower risk, researchers findDrinking champagne, eating more fruit, staying slim and maintaining a positive outlook on life could help reduce the risk of a sudden cardiac arrest, the world's first study of its kind suggests.Millions of people worldwide die every year after experiencing a sudden cardiac arrest (SCA), when the heart stops pumping blood around the body without warning. They are caused by a dangerous abnormal heart rhythm, when the electrical system in the heart is not working properly. Without immediate treatment such as CPR, those affected will die.

Just Stop Oil, the climate activism group behind motorway blockades, petrol station disruption and tomato soup attacks on major artworks, has disbanded after staging a final action in London this weekend. To find out why the group has decided to hang up the famous orange high-vis, Madeleine Finlay hears from our environment correspondent Damien Gayle who has been covering Just Stop Oil since its inception. He explains how policy wins and policing crackdowns combined to bring the movement to a close, and what the future of climate activism could look like in its wakeWhat next for climate activism now Just Stop Oil is hanging up the hi-vis'?Support the Guardian: theguardian.com/sciencepod Continue reading...
The Lunar Hatch project aims to blast eggs into space, hoping that aquaculture will provide protein for astronauts on missionsAt first glance, there doesn't seem to be anything special about the sea bass circling around a tank in the small scientific facility on the outskirts of Palavas-les-Flots in southern France. But these fish are on a mission.When fully grown, they will produce offspring that will be the first to be launched into space as part of a scientific project called Lunar Hatch that is exploring whether sea bass can be farmed on the moon - and eventually Mars - as food for future astronauts.

Donald Trump ignited a scramble that is transforming space from shared frontier to private asset - raising questions about law, equity and ethicsIn 2015, a rare moment of US congressional unity passed the Space Act - to mine asteroids as if they wereopen seams of ore and harvest planets like unclaimed farmland. Quietly signed by PresidentBarack Obama, it now reads as a premature act of enclosure: staking titles in a realm we scarcely understand. Though some expressed concerns at the time, it was justified by the idea of inevitable progress. Such naivety evaporated with Donald Trump. Space had been humanity's last commons, shielded by a 1967 Outer Space treaty. MrTrump declared it dead in 2020, signing the ArtemisAccords and enlisting 43allies, including the UK, in the legalisation of heaven's spoils. In March, MrTrump vowed to plant the stars and stripes on Mars - and beyond. The age of celestial commons was brief, if it ever began.A new report by the Common Wealth thinktank, titled Star Wars, warns that a powerful coalition - composed of private corporations, billionaires such as Elon Musk and Jeff Bezos, and neoliberal" thinktanks - is working to extend earthly ownership structures to space. The report's author, Durham University's Carla Ibled, calls it the transfer of shared resources into the hands of a few". The 1967 treaty bans state exploitationof space, but is vague on private claims -aloophole now fuelling a tycoon-led scramble for thestars. The aim is obvious: to act first, shape norms and dare others to object.Do you have an opinion on the issues raised in this article?

Intriguing advances hold out the possibility - but first we have to agree on what life' meansCreation of Life", read the headline of the Boston Herald in 1899. Lower Animals Produced by Chemical Means." The report described the work of the German-American marine biologist Jacques Loeb, who later wrote: The idea is now hovering before me that man himself can act as a creator, even in living nature."In fact, Loeb had merely made an unfertilised sea urchin egg divide by exposing it to a mixture of salts - he was not even close to creating life in the lab. No scientist has ever done that. But that ancient dream hovers today over the discipline called synthetic biology, the very name of which seems to promise the creation of artificial life forms. Take one of the most dramatic results in this field: in 2010, scientists at the J Craig Venter Institutes in Maryland and California announced they had made the first self-replicating synthetic bacterial cell".

This albino toad was produced by a team of scientists with one foot in a Sydney university laboratory and the other in a research station on the vast tropical savannahs and wetlands far away to the north near Humpty Doo.It was September 2023 and for the man who dreamed it into being, the toad was but an opening act in a radical new play against one of the world's worst invasive species.Sign up for a weekly email featuring our best reads Continue reading...
The health secretary has pledged to fight chronic illness, but experts say he risks increasing it with department cutsThe US health secretary, Robert F Kennedy Jr, entered office with a pledge to tackle the US's chronic disease epidemic and give infectious disease a break". In at least one of those goals, Kennedy has been expeditious.Experts said as Kennedy makes major cuts in public health in his first weeks in office, the infrastructure built to mitigate Covid-19 has become a clear target - an aim that has the dual effect of weakening immunization efforts as the US endures the largest measles outbreak since 2000.

Data indicates the Cosmos 2553 - which US officials claim is aiding Moscow's development of nuclear anti-satellite weapon - may no longer be functionalA secretive Russian satellite in space that US officials believe is connected to a nuclear anti-satellite weapons program has appeared to be spinning uncontrollably, suggesting it may no longer be functioning in what could be a setback for Moscow's space weapons efforts, according to US analysts.The Cosmos 2553 satellite, launched by Russia weeks before invading Ukraine in 2022, has had various bouts of what appears to be errant spinning over the past year, according to Doppler radar data from space-tracking firm LeoLabs and optical data from Slingshot Aerospace, shared with Reuters.

They can learn hundreds of words, count to five and read humans like a book, so why do we struggle to understand them? Scientists reveal the truth about our pets - and whether they ever feel guilty for eating our slippersThe thing that made me think my dog may be a genius was the word monkey. We'd developed a game where I'd hide her monkey toy - a sad, lifeless being, long lobotomised by my golden retriever puppy - and, when I asked her to find it, I realised she could differentiate the word monkey from other objects. A woman in the park had a similar story. On holiday in an unfamiliar cottage, she had misplaced the car keys. After hunting for them for over an hour, her dog, a border collie, overheard her and her husband talking about it, recognised the word keys" and immediately went and foundthem.So maybe my dog, Rhubarb, isn't a genius after all. Dogs, says Vanessa Woods, director of the Puppy Kindergarten project at Duke University in North Carolina, US, and writer of several books including Puppy Kindergarten: The New Science of Raising a Great Dog, can know hundreds of words for objects. Over 1,000, probably," she says. And actually it's more interesting than that, because they learn words the way children learn words, and that's not by repetition." Psychology professor Juliane Kaminski showed back in 2004 that a dog called Rico (another border collie), could learn, as children do, by inference - he didn't need to know the name of a new toy, he could work it out by excluding the toys he did know the names of.

Experts hope vessel's old timbers and nails will help shed light on how boats were built during medieval periodArchaeologists excavating the site of a former fish market in Barcelona have uncovered the remains of a large medieval boat that was swallowed by the waters off the Catalan capital 500 or 600 years ago.The area, which is being dug up in order to build a new centre dedicated to biomedicine and biodiversity, has already yielded finds ranging from a Spanish civil war air-raid shelter to traces of the old market and of the city's 18th-century history.

I need to stop dwelling on everything I get wrong, from sending my ball into the drink to squeezing the wrong bottomWhether you're into sport or not, there's wisdom to be mined from it. Once you've picked your way through the platitudes, banalities and cliche there's gold in there.Rory McIlroy's famous victory at the US Masters earlier this month yielded, for me anyway, a particularly good example. McIlroy's psychologist, Bob Rotella, has been credited with helping his man develop golf's key mental skill: putting your bad shots behind you and barely giving them a second thought.

The condition is more excruciating than childbirth or gunshot wounds, but little understood. An online community of clusterheads' are self-experimenting with psilocybin - with promising resultsPeter was working late, watching two roulette tables in play at a London casino, when he felt something stir behind his right eye. It was just a shadow of sensation, a horribly familiar tickle. But on that summer night in 2018, as chips hit the tables and gamblers' conversation swelled, panic set in. He knew he only had a few minutes.Peter found his boss, muttered that he had to leave, now, and ran outside. By then, the tickle had escalated; it felt like a red-hot poker was being shoved through his right pupil. Tears flowed from that eye, which was nearly swollen shut, and mucus from his right nostril. Half-blinded, gripping at his face, he stumbled along the street, eventually escaping into a company car that whisked him home, where he blacked out. Continue reading...
A bracingly hopeful call for high-flyers to ditch corporate drudgery in favour of something far more ambitiousThis is not a self-help book," the author tells us, firmly. Appearances might suggest otherwise: it is written and presented almost entirely in the familiar style of that genre, with largish print, short sentences, snappy maxims in italics and lots of lists and charts (six signs you may be on the wrong side of history"). Its proposals are delivered with all the annoyingly hectic bounciness ofthe genre.But it is worth taking Bregman (a thirtysomething historian and author labelled one of Europe's most prominent young thinkers" by the Ted network) at his word. He begins from the deep and corrosive anomie experienced by so many gifted young professionals who find themselves making substantial sums of money in exhausting and (at best) morally compromising jobs. The moral ambition" of the title is about recognising that serious financial, organisational, technological and analytical skills - the kind that in the US will get you through, say, law school with a secure ticket to prosperity - can be used to make tangible improvements in the lives of human and nonhuman neighbours.

Rock deposits provide first land-based evidence of Earth's largest flood, when water surged through strait of GibraltarThe event that refilled the Mediterranean basin 5m years ago is thought to have been the largest flood in Earth's history, with water surging through the present-day strait of Gibraltar 1,000 times faster than the Amazon River, filling the basin in just a couple of years. Now jumbled rock deposits on the top of hills in south-east Sicily provide the first land-based evidence for this flood.The megaflood theory emerged in 2009, when scientists discovered a massive eroded channel at the bottom of the strait of Gibraltar. Subsequent research has revealed scours on the sea floor, showing how the water forced its way through the shallow gap between Sicily and mainland Africa, to fill the eastern Mediterranean Sea.

Burying our heads in the sand won't stop the climate crisis or pandemics. We're taking action to preserve government toolsUnited States science has propelled the country into its current position as a powerhouse of biomedical advancements, technological innovation and scientific research. The data US government agencies produce is a crown jewel - it helps us track how the climate is changing, visualize air pollution in our communities, identify challenges to our health and provide a panoply of other essential uses. Climate change, pandemics and novel risks are coming for all of us - whether we bury our heads in the sand or not - and government data is critical to our understanding of the risks these challenges bring and how to address them.Much of this data remains out of sight to those who don't use it, even though they benefit us all. Over the past few months, the Trump administration has brazenly attacked our scientific establishment through agency firings, censorship and funding cuts, and it has explicitly targeted data the American taxpayers have paid for. They're stealing from us and putting our health and wellbeing in danger - so now we must advocate for these federal resources. Continue reading...

Readers critique the symbolism, substance and style of the recent all-female rocket tripFor those who have not already read Ursula K Le Guin's 1976 essay SpaceCrone, it is the perfect antidote to this weird Charlie's Angels-in-space exploit (So Katy Perry went to space. Wasn't there anyone else we could have sent?, 14 April).Le Guin rightly suggests that it is an apparently unremarkable postmenopausal woman who is the ideal candidate to represent humanity on a space mission. The crone" has a depth of experience of being human that no young, fit, looks-great-in-Lycra man or woman can match. Continue reading...

Scientists claim to have found colour no one has seen before". Congratulations on a genuinely witty double pun in the online headline on your article, which was also in Saturday'spaper under a different heading.And - forgive a little self-congratulation - my co-author Yan Wong reminds me that in our book, The Ancestor's Tale (first published in 2004, with a second edition in 2016), we wrote: This raises an intriguing possibility. Imagine that a neurobiologist inserts a tiny probe into, say, a green cone and stimulates it electrically. The green cell will now report light' while all other cells are silent. Will the brain see' a super green' hue such as could not possibly be achieved by any real light? Real light, no matter how pure, would always stimulate all three classes ofconestodifferingextents."
