Over time, she was able to more readily accept the impact of ADHD on her life without labelling this as a character flaw

I suggest to my son that the object of going to the planetarium should be for him to learn something, not to catch the scientists outSince it was half-term, I took the boy out for the day. My choice was the planetarium at the Royal Greenwich Observatory, which melds my two great loves: space and having to traverse the entirety of London, with a chatty six-year-old, twice in one wet afternoon. Our journey involves two buses, a tube, an overground, and 20 minutes of walking either side. Time was, all these various modes of transport would be a big plus for my son, who used to whoop and cheer as trains arrived and scream with contagious delight at every bus driver he met. As he moans about how long everything is taking, I realise for the first time that those mundane pleasures of the everyday world have left him. No wonder, I think with egregious lachrymosity, he has his eyes set on the stars.Being a six-year-old, he is stocked with questions. We have both presumed he will get some time with space boffins, ready and eager to answer any queries from 4ft-tall astronomers in training. It's just that my son is equally insistent that they'll be eager to learn something from him. As we take our seats on the tube, he lays out his prolix plan: a set of 14 questions sorted into four distinct classes; 4 x easy, 4 x medium, 4 x hard, and 2 x EXTREME. Continue reading...

Five years on from March 2020, millions of people still face debilitating symptoms, with huge repercussions on public health and productivity. But politicians are starting to pretend the pandemic never happenedOn 20 March 2020, Rowan Brown started to feel a tickle at the back of her throat. Over the next few days, new symptoms began to emerge: difficulty breathing, some tiredness. By the following week, the UK had been put under lockdown in a last-minute attempt to contain the spread of SARS-CoV-2, or Covid-19. No one else she knew had yet been infected, so she posted updates on Facebook to keep people informed: Oh, guys, it feels like a mild flu. Tonsillitis was definitely worse."Brown didn't know then she was at the beginning of a condition that did not yet have a name, but which has since become known as long Covid. After two weeks, she had a Zoom with a friend, and at the end of the conversation it was as if all life force had drained out of her body. Her doctor advised her to stay in bed for two weeks. Those two weeks turned into three and a half months of extended Covid symptoms: nausea, fevers, night sweats, intense muscle and joint pain, allodynia (a heightened sensitivity to pain), hallucinations, visual disturbances. By the end of the three months, she had noted 32 different symptoms. I didn't recognise the way my body felt at all: my skin, my hair," she remembers now. It was like being taken over by a weird alien virus, which I guess is what happened." Continue reading...

Academics and medics are working to understand why hamstring injuries are keeping players sidelined for longerThe sight of a player pulling up with a hamstring injury has become all too familiar in the Premier League. Weary muscles are being stretched to the limit by an expanding calendar, but dealing with more games is not the only challenge for medical departments.It is not that there has been a sudden explosion. It can simply seem that way when high-profile players such as the Arsenal forwards Bukayo Saka and Kai Havertz are long-term absentees. Using figures up to and including game week 26, that ended last Sunday, the Premier Injuries website says 100 of the 418 injuries this season related to hamstrings (24%), compared with 120 from 457 (26%) at the same stage last year.

Experts hope research can create greener methods of extracting the metal vital for renewable energy revolution and boom in electrical devicesIt is the key ingredient of bronze, the alloy that helped create some of the world's greatest civilisations and took humanity out of the stone age on its way to modern times. For good measure, the metal is invaluable for electrical wiring, plumbing and industrial machinery. We owe a lot to copper.But the metal now faces an uncertain future as manufacturers prepare to expand its use to make the electric cars, renewable power plants and other devices that will help the planet move towards net zero. Unrestricted extraction could cause widespread ecological devastation, scientists have warned. Continue reading...

Out of his depth and determined to defy stereotypes, one writer discovered his sense of self in a bracing cold dipGrowing up, I learned not to trust water. I was a poor swimmer and splashing in the sea on holiday always had a hard edge to it. The second my toes left the sandy floor I panicked, for fear of being swept away.Things changed a few years ago at a friend's birthday weekend in Cornwall. One February morning, a dozen of us took a hungover walk to the beach. It was overcast and blustery, and we had come to skinny-dip. I was buoyed up by the camaraderie and games of the night before, and felt a safety in numbers. People stripped off, actions hastened by the wind, and before I could think, I followed. We ran over sand and pebbles and dived into the oncoming waves. It was a total sensory overload. Salt filled my nose and mouth. I heard shrieks and cursing, and so much laughter. As I emerged there was a surge of adrenaline, and I couldn't stop giggling. It was scary, but I was also proud, like a child who's climbed a really big tree. Afterwards my skin tingled and as we shared a flask of tea, I felt singularly happy. Continue reading...

It was yet another reminder that Trump and his associates will turn even the sex trafficking of minors into a photo opDrum roll, please: the most transparent administration in American history" is declassifying shocking new information about Jeffrey Epstein and his associates. After years of speculation that powerful people have been concealing information related to the late financier and convicted sex offender, the Trump administration said earlier this week that it would release unseen details about the case.

Are ordinary life experiences, bodily imperfections and normal differences being unnecessarily pathologised? One doctor argues just thatSchool was a difficult time for Anna. It still haunts her. She recalls being a sociable child, good at making friends. But she also remembers becoming hyperfixated on one friend, then another and another in succession. She tended to be impulsive and, wanting to please others, easily led. One distressing incident in particular has never left her. On the first day after moving to a new school, she was relieved to be taken under the wing of two girls. At lunchtime, in fits of giggles, the girls egged each other on to do naughty things. Anna spat orange juice at the boys. She did it with relish, only to reproach herself later. She feels the episode coloured her whole school experience.As a child and an adult, Anna felt sanctioned, judged and misunderstood. She considers herself a chameleon who adapts to new environments and survives by being funny, but all too often regrets things she has said. Her self-esteem is low. Anna is a nurse and, although she loves her job and is good at it, she still often feels inadequate. People don't think I'm as clever as I feel. I can't get the words out quickly enough," she says.

The first all-female private flight into space funded by the Amazon tycoon's Blue Origin company has little to do with female empowerment and a lot to do with PRA pop star, a TV host and a billionaire's fiancee walk into a private rocket ship. The pop star turns to the others and asks: Is this what feminism looks like?" According to the space technology company Blue Origin, owned and founded by the Amazon tycoon Jeff Bezos, the answer seems to be a resounding yes.On Thursday Blue Origin announced it would be launching the first-ever all-female commercial flight to space with a crew of astronauts including US singer Katy Perry, the morning news host (- and close friend of Oprah Winfrey - Gayle King and Bezos's own partner, the journalist Lauren Sanchez, who reportedly organised the mission, which will happen sometime this spring.

Australian research is first to empirically show that we don't all love the same', lead author says

Up to 90% of young people in Taiwan have myopia but eye experts say the growing global trend can be reversedIn the final days of their eight-week bootcamp, dozens of young Taiwanese conscripts are being tested on an obstacle course. The men in full combat kit are crawling underneath rows of razor wire and through bunkers as controlled explosions blast columns of dirt into the air. Pink and green smoke blooms in a simulated gas attack, requiring the conscripts to quickly don gas masks so they can rush the zone. But it's here where many of them pause, stopping the assault drill to spend precious seconds removing their glasses so the masks will fit.The conscripts mostly look to be in their early 20s. Statistics suggest that means anywhere up to 90% of them have some degree of myopia, otherwise known as shortsightedness. Continue reading...

The recent hand jiu-jitsu' with Keir Starmer is just the latest awkward exchange between the US president and world leadersAs Keir Starmer handed Donald Trump his unprecedented invitation from King Charles - a second state visit - he grasped the US president chummily by the shoulder, more than once.Starmer was skating a tricky line, between matey familiarity and patronising reassurance, which must have been tutored, as he's not a tactile man. Trump's body language looked completely untaught, because nobody could teach this. The man has always been incredibly idiosyncratic. Continue reading...

Dr Wendy Tagg has missing photos in her album of memories, while Judith Abbs says there isn't a word for a sibling who is now aloneJason Hazeley's piece on the death of his sister (When my sister died, it wasn't just her own childhood memories that disappeared. Mine did too, 24 February) took me right back to a vague memory of hurtling down a snowy hill on the big wooden sleigh that my father had made.The real loss is that I can't ask mybig brother. He would have known which hill it was, the route we took, whether we drove there inthe blue Reliant or the beige Morris, whether I was wearing the red woolly coat that was once his. I, too, have missing photos in my album of memories.

Activist Amanda Nguyen, movie producer Kerianne Flynn and former Nasa scientist Aisha Bowe will also be on flightJeff Bezos announced on Thursday that an all-female crew would helm the next flight into space of a Blue Origin rocket. The singer Katy Perry will join the television host Gayle King, the civil rights activist Amanda Nguyen, the movie producer Kerianne Flynn, the former Nasa rocket scientist Aisha Bowe and Bezos's fiancee, Lauren Sanchez, on a short hop from a west Texas launchpad this spring.The 11th crewed mission of its New Shepard capsule, which the billionaire's space company announced in a press release, will mark the first time since Russian cosmonaut Valentina Tereshkova's solo flight in 1963 that no men have been aboard a human-crewed spaceflight leaving Earth, Blue Origin said.

Scientists find sterile ISS environment could explain rashes and cold sores and suggest adding microbes to stationsExcessive cleanliness is not generally regarded as a downside when it comes to travel accommodation. However, scientists have concluded that the International Space Station is so sterile that it could be having a negative impact on astronauts' health and have suggested making it dirtier".The study found that the ISS is largely devoid of environmental microbes found in soil and water that are thought to beneficial to the immune system. The lack of microbial diversity could help to explain why astronauts often experience immune-related health problems such as rashes, cold sores, fungal infections and shingles. Continue reading...

When the palaeontologists of the future search for clues to understand how we lived, what might they find? Two scientists exploring this question have suggested that technofossils' will be our lasting imprint on the Earth. To find out exactly what these are and what they could reveal about our lives, Madeleine Finlay hears from the Guardian's environment editor, Damian Carrington, and from Sarah Gabbott, a professor of palaeontology at the University of Leicester and one of the scientists behind the new book Discarded: How Technofossils Will Be Our Ultimate LegacySupport the Guardian: theguardian.com/sciencepodTechnofossils': how humanity's eternal testament will be plastic bags, cheap clothes and chicken bones Continue reading...

Trump has the classic authoritarian personality - not the same as being authoritarian, writes Mary Wilkinson, plus, letters by Tom Brown, Jim Hatley, Sally Burch and Alison RouthJonathan Freedland's comments about Donald Trump highlighted two Trumps: the shoot-from-the-hip tough guy and the supplicant at the court of Vladimir Putin (Trump is the world's greatest showman - and the weakest strongman it has ever seen, 21 February). Isn't he an example of the authoritarian personality (not to be confused with being authoritarian)?Rupert Wilkinson's 1972 book The Broken Rebel explored the subject. Some of the characteristics of the authoritarian personality that he listed are submission to a strong, admired authority; aggressive hostility to people in authority whose traits he resents, often as a result of being dominated himself in childhood or to compensate for a sense of weakness; open hostility to outsiders and admiration for his own side; a desire to be strong, to hold power and assert it aggressively; detests ambiguity and uncertainty; craves simple solutions and obvious results.

Earth's plants and soils reached peak carbon dioxide sequestration in 2008 but proportion absorbed has been declining since, study findsOur planet is losing its appetite for mopping up carbon dioxide. Analysis of atmospheric carbon dioxide measurements show that Earth's plants and soils reached peak carbon dioxide sequestration in 2008 and absorption has been declining ever since. Passing this tipping point increases the chances of runaway climate breakdown.Plants and trees have had it good for the last century or so. Rising levels of carbon dioxide helped to spur growth and warmer temperatures gave rise to a longer growing season. But at some point these benefits start to be outweighed by the negatives of a warming climate: wildfires, drought, storms, floods, the spread of new pests and diseases and plant heat stress all reduce the amount of carbon dioxide that plants absorb.

From ghost trains to backstreet weddings, from demolition sites to alien's eye views' of Leeds, groundbreaking photographer Peter Mitchell captures our changing world with his trusty Blad' - and once even tried to leave itThe Quarry Hill flats in Leeds were once the largest social housing complex in the UK. A utopian vision of homes for 3,000 people. Built in the 1930s, they were modelled on the Karl-Marx-Hof in Vienna and La Cite de la Muette in Paris. However, after just 40 years, the buildings were crumbling and largely deserted. Over the course of five years in the 1970s, Peter Mitchell documented their demolition, from smashed windows and wrecked apartments to abandoned wardrobes and solitary shoes. Finally, when all that was left standing was a lone arch, he tried to photograph the wrecking crew standing in front of it, but couldn't get the arch in.So," Mitchell remembers, the foreman said, We do have a crane.' I can't stand heights but they lowered the crane down so I could stand on it, then lifted me up to quickly get the shot. I was swaying about a bit and all but one of them came out blurred - but I got the picture." Continue reading...

For the next few weeks we're asking readers to nominate their invertebrate of the year: click here to give us your suggestionsDoes a worm feel pain if it gets trodden on? Does a fly ache when its wings are pulled off? Is an ant happy when it finds a food source? If so, they may be sentient beings, which means they can feel", a bit or a lot, like we do.Invertebrate sentience is becoming an ever livelier topic of debate and with new science we are getting new insights. But Dr Andrew Crump at the Royal Veterinary College, who helped ensure that new UK laws recognising animal sentience were amended to include large cephalopod molluscs and decapod crustaceans - octopuses, lobsters, crabs to you and me - says this is not at all straightforward.

For more than 20 years, scientists have followed the animals in Norway's Arctic archipelago to understand how they may adapt to changing threats as the ice they depend on meltsWhen Rolf-Arne Olberg is hanging out of a helicopter with a gun, he needs to be able to assess from a distance of about 10 metres the sex and approximate weight of the moving animal he is aiming at, as well as how fat or muscular it is and whether it is in any distress. Only then can he dart it with the correct amount of sedative. Luckily, he says, polar bears are quite good anaesthetic patients".Olberg is a vet working with the Norwegian Polar Institute, the body responsible for the monitoring of polar bears in Svalbard, an archipelago that lies between mainland Norway and the north pole. Every year he and his colleagues track the bears by helicopter, collect blood, fat and hair samples from them and fit electronic tracking collars. Continue reading...

Keep an eye on the western sky for the pairing - and you may also see Mercury hovering over the horizonThis week, we keep an eye on the western sky to catch glorious Venus and a young crescent moon.The chart shows the view looking west from London at 19.00 GMT on the evening of 2 March. At this point, the moon will be just over three days old and have just 10% of its visible surface illuminated. While the pairing will not be particularly close, it will still be a beautiful sight. Venus remains in Pisces, the fishes, which is one of the fainter constellations and, although now on the wane, the planet will still be gloriously brilliant. Continue reading...

Health department orders NIH to hold Federal Register submissions - critical step in process for funding studiesThe Trump administration has blocked a crucial step in the National Institutes of Health (NIH) process for funding medical research, likely in violation of a federal judge's temporary restraining order on federal funding freezes.The NIH has stopped submitting study sections - meetings in which scientists peer review NIH grant funding proposals - to the Federal Register after the Trump administration paused health agency communications. By law, study sections must appear on the register 15 days in advance of meetings. Continue reading...

Startling evidence of the dangers to birds and rivers from over-the-counter drugs should be a wake-up call for owners to press for alternativesWhen I was 10, I succeeded in my campaign for a family dog. Part of her care, and our joy as owners, was the monthly application of spot-on worm and flea treatment. With veterinary medicine on my mind as a career, I relished the theatre of vets-at-home. We bought doses over the counter, scheduling the dog's treatment on the calendar like a five-a-side.We applied these drugs to our dog because every other owner did. Because it was encouraged, because it was easy, because it felt right.Sophie Pavelle is a writer and science communicatorDo you have an opinion on the issues raised in this article?

What started as curiosity would turn into an emotional investment - and eventually, a lifelineA few nights ago, my phone lit up with a TikTok notification: WE'RE PREGNANT". The message wasn't from a friend. It was from an Australian couple, complete strangers. But social media knows me well because I felt something sharp and bright - joy and relief - for people I will never meet.It's strange to feel deeply for someone you've never spoken to, whose life is about as geographically far from yours as possible. But I was thrilled to see this pregnancy announcement, shared with millions, from someone I only knew through a few carefully curated moments. As someone who is fundamentally nosy - I will never not notice a baby on board" badge or make up backstories for strangers - social media has always offered an irresistible window into other people's lives.

Pin-prick blood tests that detect possible precursors of Alzheimer's disease are becoming available - but is it right to label people who will never develop the disease?It's difficult to say when he first began noticing the signs, says Chris. He was living abroad and communicated with his parents on Skype. During these calls, his mother would sometimes repeat herself, asking the same question just minutes later. We didn't think much of it, we assumed it was due to technical problems." Then his father mentioned that there was something wrong with her memory. Mum being only 63, I didn't believe him." But two years later, during a Christmas break abroad, when his mother went upstairs to use the toilet and couldn't find her way back down, they knew there was something up.Shirley was diagnosed with Alzheimer's disease at the age of 67 by a GP using a cognitive test that includes drawing a clock with a certain time on a piece of paper. She received the diagnosis via a letter that consisted of only one line. I look at that letter and I am appalled by it," says Chris. My mother never saw a neurologist. It was such a thin diagnosis. We thought this can't be right, she's too young." Continue reading...

2024 YR4, a lump of rock the size of a building, may be heading our way, but don't start stockpiling the tinned carrots yetFollowing the possible trajectory of 2024 YR4 - AKA the scariest asteroid ever detected - is not for the nervous of disposition. Is it going to hit us, or not? Every day, a different answer.Last Tuesday, Nasa calculated it had a 3.1% chance of hitting Earth in 2032, and so some people set to worrying. Twenty-four hours later, however, the agency provided an update. New observations, made since the passing of the full moon, show it now has a 1.5% chance of impact. Time to exhale? Not necessarily.

The So Hot Right Now conference will put the spotlight on dosages advocated by three headline speakers whose claims are disputed by other experts

A probe to be launched this week aims to pinpoint sites of lunar water, which could help plan to colonise the Earth's satelliteSpace engineers are set to launch an unusual mission this week when they send a probe built by UK and US researchers to the moon to map water on its surface. Lunar Trailblazer's two year mission is scheduled to begin on Thursday when the probe is blasted into space from Florida on a Space X Falconrocket.Its goal - to seek out water on the lunar surface - may seem odd given that the moon has traditionally been viewed as an arid, desiccated world. However, scientists have recently uncovered strong hints that it possesses significant quantities of water. It will be the task of Lunar Trailblazer to reveal just how much water there is near the lunar surface and pinpoint its main locations. Continue reading...
