Over the coming months, the planet will be in retrograde motion, and will also appear brighter as it draws closerThe moon will help us track down Saturn, the sixth planet in the solar system, this week. Currently residing in the constellation of Pisces, the fishes, Saturn is gradually building in brightness as the Earth's orbit is carrying the two planets closer together. This year, the closest approach between them will occur on 21 September.In the meantime, the moon can be useful as your guide to locate Saturn and then watch it over the coming months as the planet performs a lazy pirouette in the sky, known as retrograde motion. This is an optical illusion caused by our changing line of sight to the planet as Earth overtakes it on the inside. Continue reading...

Hollingside lane, Durham: Pleated inkcaps may live for a day but here we've been watching other fungi, such as dryad's saddle, grow since springThere were none here yesterday, and by the end of tomorrow they'llhave deliquesced and disappeared, but for now the neatly mown grass under our feet was studded with 2in-tall parasol inkcaps (Parasola plicatilis). They looked like an invasion of tiny parachutists; in reality they'd risen from the underworld.They were here all along, as a mycelium of microscopically slender hyphae, down among the grassroots. Autumn is the fungal forager's season but fungi, as hyphae or spores, are everywhere, unseen, all the time. Occasionally, driven by the imperative to reproduce, their ramifying network of independent threads collaborates, producing spores in toadstools. Some, like these inkcaps, are ephemeral; others, like the dryad's saddle (Cerioporus squamosus) we'd been watching since spring, grow from teacup to tea-tray proportions, slowly digesting dead wood, taking months to reach maturity.

Finalists for 2025 will be exhibited at Hobart's Tasmanian Museum and Art Gallery from 6 to 31 August as part of the Beaker Street festival and will include the first-ever image of a wild eastern quoll glowing under UV light

Do you scream when you stub your toe? Could you play a grand final with a shattered jaw, or work all day as your belly fills with blood? When it comes to suffering, perspective is everythingSome say it was John Sattler's own fault. The lead-up to the 1970 rugby league grand final had been tense; the team he led, the South Sydney Rabbitohs, had lost the 1969 final. Here was an opportunity for redemption. The Rabbitohs were not about to let glory slip through their fingers again.Soon after the starting whistle, Sattler went in for a tackle. As he untangled - in a move not uncommon in the sport at the time - he gave the Manly Sea Eagles' John Bucknall a clip on the ear. Continue reading...

Michael Kirk Moore accused of distributing at least 1,937 false vaccination cards and administering saline to childrenThe US Department of Justice dropped charges on Saturday against Michael Kirk Moore, the Utah doctor accused of destroying more than $28,000 worth of government-provided Covid-19 vaccines and administering saline to children instead of the shot.Pam Bondi, the US attorney general, announced the news in a statement on the social media platform X, saying the charges had been dismissed under her direction.

Widespread mockery of AI-generated rat with giant penis in one paper brings problem to public attentionIt was, at first glance, just another scientific paper, one of the millions published every year, and destined to receive little to no attention outside the arcane field of biological signalling in stem cells destined to become sperm.But soon after the paper was published online, in the journal Frontiers in Cell and Developmental Biology, it found a global audience. Not all of the readers came for the science. Continue reading...

Previously, the only way to reduce levels of Pfas was by bloodletting or a drug with unpleasant side effects

Centre for animal sentience to look into animal consciousness and the ethical use of AI in how we treat themIf your cat's sulking, your dog's whining or your rabbit's doing that strange thing with its paws again, you will recognise that familiar pang of guilt shared by most other pet owners.But for those who wish they knew just what was going on in the minds of their loyal companions, help may soon be at hand - thanks to the establishment of the first scientific institution dedicated to empirically investigating the consciousness of animals.

The International Space Station has been flying over the country this week and excited children tracking Shubhanshu Shukla's every move will be hoping for a glimpse of his temporary home on Saturday nightAs the International Space Station passes over India this weekend, many of those looking up to catch a glimpse as it goes by will be excited schoolchildren, who, like millions across the country, have their eyes, hopes and dreams pinned on astronaut Shubhanshu Shukla, the first Indian to visit the ISS.What if the astronauts find evidence of intelligent life forms in space? Or even better, what if Shubhanshu Shukla's experiments help humans discover a way to survive on other planets?" says Deborshi Halder, an excited 15-year-old. His classmate, however, is concerned. But if places beyond Earth become habitable, we humans may land up exploiting them too, leading to space pollution," says Sabnam Sireen. Continue reading...

My father, Arthur Callaghan, who has died aged 93, was a biology lecturer at Staffordshire University and passionately committed to blue sky" research: scientific endeavour for its own sake. His investigation of the natural world, in particular the study of fungi and their interactions with microscopic organisms, sustained a deep fascination that lasted throughout his life.Part of his research involved the study of the fungi Conidiobolus and Basidiobolus, and their saprotrophic and pathogenic qualities (ie species' ability to colonise and obtain nutrients from dead microscopic animals such as mites and springtails, or infect and kill them). In 1989, he co-discovered and named, with Steve Waters, a new species, Conidiobolus iuxtagenitus. Continue reading...

From cows and cats to squirrels and birds, all have their own methods but may need more help as heatwaves intensifyWith the UK bracing for its third heatwave of the summer, 2025 is on course to be a record-breaking year for temperature. As people retreat into paddling pools and beneath the breeze of pedestal fans, a quieter and less visible struggle is playing out across the country's fields, forests and hedgerows. So how are Britain's animals weathering the heat?From cows and cats to herons, horses and even earthworms, each species has evolved its own tactics for staying cool - some more effective than others. But as extreme heat events become more frequent and intense, scientists are beginning to question the longer-term resilience of UK wildlife, and what we can do to help. Continue reading...

Colossal Bioscience is adding the extinct animal to its revival wishlist, joining the woolly mammoth, dodo and thylacine. But scepticism is growingStanding more than three metres (10ft) high, the giant moa is the tallest bird known to have walked on Earth. For thousands of years, the wingless herbivore patrolled New Zealand, feasting on trees and shrubs, until the arrival of humans. Today, records of the enormous animal survive only in Mori oral histories, as well as thousands of discoveries of bone, mummified flesh and the odd feather.But this week, the US start-up Colossal Biosciences has announced that the giant moa has joined the woolly mammoth, dodo and thylacine, or Tasmanian tiger, on its list of animals that it is trying to bring back from the dead. The announcement has provoked public excitement - and deep scepticism from many experts about whether it is possible to resurrect the bird, which disappeared a century after the arrival of early Polynesian settlers in New Zealand about 600 years ago.

Neuroscientist, author, political activist and advocate for social responsibility in scienceScience and politics can make awkward bedfellows, with the very question of whether it is possible to make purely objective observations about the world drawing forth highly politicised positions. The neurobiologist Steven Rose, who has died aged 87, took a broadly reductionist approach to his research into biochemical mechanisms of memory, while at the same time adopting a high-profile political stance against the idea that human behaviour is determined by our genes.Less publicly but equally influentially, as the first biology professor to be appointed at the Open University - the distance-learning institution founded through a Labour government initiative in 1969 - Rose helped to pioneer a democratic and distributed approach to teaching practical science. He developed experiments that students could complete at home, pooling their results and prefiguring many of the citizen science" projects that have become popular in recent years.

Watchdog releases nine new rulings setting clear precedents for online sellingOnline pharmacies are no longer allowed to run adverts for weight loss injections, the advertising watchdog has ruled, as part of a crackdown on what has been described as a wild west" culture of online selling.In the UK, advertising prescription-only medications (POMs) - which includes all weight loss jabs such as Wegovy and Mounjaro - to the public is illegal. However, a Guardian investigation previously found some online pharmacies either breaking these rules outright, or exploiting grey areas to peddle the medications to the public. Continue reading...

Experts scrambling to understand losses in hives across the country are finally identifying the culprits. And the damage to farmed bees is a sign of trouble for wild bees tooBret Adee is one of the largest beekeepers in the US, with 2 billion bees across 55,000 hives. The business has been in his family since the 1930s, and sends truckloads of bees across the country from South Dakota, pollinating crops such as almonds, onions, watermelons and cucumbers.Last December, his bees were wintering in California when the weather turned cold. Bees grouped on top of hives trying to keep warm. Every time I went out to the beehive there were less and less," says Adee. Then a week later, there'd be more dead ones to pick up ... every week there is attrition, just continually going down." Continue reading...

Research in Chile suggests climate crisis makes eruptions more likely and explosive, and warns of Antarctica riskThe melting of glaciers and ice caps by the climate crisis could unleash a barrage of explosive volcanic eruptions, a study suggests.The loss of ice releases the pressure on underground magma chambers and makes eruptions more likely. This process has been seen in Iceland, an unusual island that sits on a mid-ocean tectonic plate boundary. But the research in Chile is one of the first studies to show a surge in volcanism on a continent in the past, after the last ice age ended. Continue reading...

The brilliant planet will move across the invisible line between the pair and appear 3 degrees away from the star AldebaranThis week, Venus will pass through the so-called Golden Gate of the Ecliptic. Although the name has risen to prominence with science popularisers in recent decades, its exact origin is unknown.It references two star clusters in the constellation Taurus, the Bull. The Hydes and the Pleiades lie on either side of the ecliptic, which is the plane of the solar system. As such, the sun, the moon and the planets all follow this line in their passage through the sky. The constellations the ecliptic passes through are known as the zodiacal constellations, referred to in popular culture as the signs of the zodiac. Continue reading...

Detectorists and archaeologists sometimes clash, but the recent find of two Roman swords was the thrilling result of collaborationThe discovery of two swords at a dig in Gloucestershire has fuelled speculation that a Roman villa may once have stood there, at a period in the second or third century AD when Saxons were making inroads in the region. Experts think that the blades may even have been deliberately hidden - but not deep enough to concealthem from a novice metal detectorist, GlennManning. Next month, the public will get a chance to see the weapons when they go on display at the Corinium museum in Cirencester, to which they havebeen given.The items join a growing list of striking finds by hobbyists. These include a gold nugget found in the Shropshire Hills by Richard Brock, who located it with the help of an old machine that was only half working". Another newcomer dug up a gold necklace bearing the initials of Henry VIII and Katherine of Aragon, which is now in the British Museum. Continue reading...

Cardiologist who empowered paramedics and the general public to restart hearts and save livesIf you had a cardiac arrest before the 1970s, an ambulance might arrive quickly, but almost all its crew could do was transport you to hospital, where your treatment would begin - if indeed you survived the journey. The cardiologist Douglas Chamberlain, who has died aged 94, realised that in order to start resuscitation in the vital five-minute window after the heart stopped beating, the ambulance crew needed the tools and skills to do it themselves.Chamberlain's initiative laid the foundations for the paramedic profession nationally and internationally. Working from a district general hospital in Brighton, he set up an intensive training programme for ambulance crews, equipped ambulances with defibrillators and electrocardiogram (ECG) machines, and demonstrated through a series of rigorously documented studies that the service saved lives. The only other city in the world where non-medical professionals were using defibrillators at the time was Seattle in the US. Continue reading...

Fish or bird ownership showed no significant link to slower cognitive decline in study with implications for ageing societiesAs global population ages and dementia rates climb, scientists may have found an unexpected ally in the fight against cognitive decline.Cats and dogs may be exercising more than just your patience: they could be keeping parts of your brain ticking over too. In a potential breakthrough for preventive health, researchers have found that owning a four-pawed friend is linked to slower cognitive decline by potentially preserving specific brain functions as we grow older.

From blockbuster movies like Jurassic World Rebirth to documentary series, the appetite for these ancient creatures appears inexhaustibleOn-screen discussions of DNA and off-screen scientific consultants notwithstanding, no one goes to see a Jurassic Park movie for its realism. Yet one of the less convincing moments in Jurassic World Rebirth, the latest in the franchise, is unrelated to oversized velociraptors. It's the palaeontologist Dr Henry Loomis complaining of shrinking public interest in his field.This spring, the BBC revived its 1999 hit series Walking With Dinosaurs. Not a week goes by without headlines announcing the discovery of a new species or new theories on how they behaved. Publishers produce an endless stream of dino-related fact and fiction, particularly for children. Palaeontology - at least when focused on the dinosaurs of the Mesozoic, or our hominin forebears - has long exerted an extraordinary hold on the public imagination.Do you have an opinion on the issues raised in this article?

Rachel Reeves's distress may help destigmatise an emotional response to pressure or professional frustrationRachel Reeves's tears this week triggered a fall in the pound and attracted widespread derision from political columnists, mostly male. What is wrong with Rachel Reeves?" the Telegraph asked. In an article headlined The meaning of the chancellor's tears", a New Statesman columnist told readers that Reeves's authority was beginning to melt away". The Daily Mail spoke disdainfully of her waterworks".But in the longer term the chancellor's display of distress may prove to have an unexpectedly positive legacy, helpfully normalising a still hugely stigmatised phenomenon: women's tears in the workplace.

Local clinics and technology could drive improvement if reorganisation doesn't slow things downThe NHS is a totemic institution in Labour's history and that of the country, and voters care more about it than most things the government does. So the publication of Labour's 10-year plan for health in England was a crucial opportunity for ministers to show that they are in tune with the public. Given that satisfaction with the health service has hit a record low of 21%, and doctors are again threatening to go on strike, the announcement was also a moment of peril - even before the damage suffered by the prime minister and chancellor earlier this week, when rebels forced a U-turn on planned cuts to welfare.The overarching principles of Labour's reforms were set out last year: more prevention, more technology, more care delivered in the community (as opposed to in hospital). So the challenge was to find something fresh, original and hopeful to say. The promise of science and the potential of localism are what Wes Streeting's team has come up with. The strand of DNA pictured on the document's cover points to high expectations of genomic medicine and other cutting-edge technology. Neighbourhood clinics, by contrast, represent a prosaic recognition of demand for more ordinary services and treatments, from an ageing and increasingly unhealthy population. The aim is to deliver most outpatient care away from hospitals by 2035.Do you have an opinion on the issues raised in this article?
