Women are twice as likely to get their tubes tied than men are to get the snip, even though tubal ligation is more invasive, riskier and harder to reverse. It’s time men step upAmerican men have come a long way, baby. They spend more time with their kids than ever before. Most of them say they want egalitarian marriages and better work-life balance. Two-thirds of married fathers have a wife who works outside the home and contributes to the family income, and about four in 10 of those men have a wife who outearns them. So why, when it comes to family planning, are women doing all the work and men doing so little? To put a finer point on it: why don’t more American men get vasectomies?The contraception gap is one of the most striking and persistent gender inequities. While close to 100% of American women take steps, at some point in their lives, to prevent pregnancy, the vast majority of them shoulder that burden alone. Fewer than one in 10 relied on condom use – a contraceptive method that requires men to take action. And only about one in 10 married or coupled men have had a vasectomy – the rate for single men is far lower. Continue reading...
Researchers say AI tool could lead to earlier diagnoses that could improve patients’ outcomesIt’s been used to detect eye diseases, make medical diagnoses, and spot early signs of oesophageal cancer. Now it has been claimed artificial intelligence may be able to diagnose dementia from just one brain scan, with researchers starting a trial to test the approach.The team behind the AI tool say the hope is that it will lead to earlier diagnoses, which could improve outcomes for patients, while it may also help to shed light on their prognoses.

With a new set about to be released, it’s time to consider how these little symbols enhance the way we communicateThroughout history, writing systems have reflected available technologies. Ancient Mesopotamian cuneiform featured triangles and lines because the characters were impressed into clay with a dowel; ancient Germanic runes were distinguished by angular shapes instead of curves because they were etched into stone. Now, with electronic writing and emojis at our fingertips, even those without any artistic talent can easily “write” a number of pictorial symbols, from a smirk to a syringe, from a bento box to a pregnant man.With emojis on the mind following the Unicode Consortium’s recently released draft of the newest forthcoming set, Emoji 14.0, it is a good time to ponder the relationship between emojis and the mind. Research conducted within the last few years has allowed us to begin answering some of these questions, such as whether emojis are language – and whether we can think in emojis. Continue reading...
More than 100,000 Britons under 25 have endured months of debilitating symptoms, while doctors struggle to help and others fail to take them seriously. Four young people describe what it’s likeIt took Niamh 20 minutes to wash her face – and she cried the whole time. That was in December 2020 when the 19-year-old first-year student at the University of Leeds had been living with long Covid for two months. “I didn’t have the energy to move my arms,” she says. She remembers sitting on the toilet, trying to muster the strength to stand up and run the tap. It took all her energy just to switch on the water. “It sounds daft, but I cried,” she says. “I was like, what is happening to me?”Niamh had led a physically active life until then. She went to the gym regularly and had swum competitively at school. But after catching Covid in freshers’ week, she became a shell of her former self. She would wake up in the morning and feel overwhelmed by a tiredness that felt as if it was deep in her bones. “I have never felt fatigue like it,” she says. “It was as if I’d been hit by a train or run a marathon.” Gentle activities, such as taking a walk with friends, would leave her gasping for breath. She couldn’t smell or taste anything. She had chest pains and palpitations. Mostly, she lay in bed, scrolling through social media and trying to ignore the thought that she was missing out on the student experience she had longed for. Continue reading...

The climate crisis is ‘unequivocally’ caused by human activities, according to a report from the IPCC. One attempt to conserve the environment, being pushed by Boris Johnson, is to protect 30% of UK land in a boost for biodiversity. A Guardian exclusive found that an area twice the size of Greater London is devoted to grouse shooting in UK national parks, which threatens efforts to tackle the climate crisis. Patrick Greenfield and Phoebe Weston investigate whether national parks benefit the environment and biodiversity, or if there might be a better way of doing things Continue reading...

The world’s political leaders must heed the dramatic warning that climate scientists have deliveredThe sixth report of the Intergovernmental Panel on Climate Change (IPCC) was published against a glowing backdrop of orange skies, as vast wildfires sweep through Greece and California. In western Germany, thousands of homes remain without running water or electricity following the devastating floods of July. In Yakutsk in Siberia – the coldest winter city on earth – residents were warned last month to stay inside as forest fires filled the air with toxic smoke, following heatwaves that began in the spring.Eight years in the making, authored by the world’s leading climate scientists and approved by 195 national governments, the report confirmed the meaning of the evidence before our eyes: the cumulative impact of human activity since the Industrial Revolution is “unequivocally” causing rapid and potentially catastrophic changes to the climate. The future that environmental scientists foresaw with alarm, when the IPCC produced its first report three decades ago, has arrived. Continue reading...
Doctors express concern that record figures reflect prevalence of virus and issue of vaccine hesitancyA record number of pregnant women were admitted to intensive care with Covid last month, data shows, as doctors raised concerns about vaccine hesitancy among expectant mothers and urged them to get jabbed as soon as possible.Figures from the Intensive Care National Audit and Research Centre (ICNARC) showed that in England, Wales and Northern Ireland 66 pregnant women ended up in intensive care in July, the highest number since the pandemic began and three times as many as April last year. A total of 46 recently pregnant women were also admitted to critical care. Continue reading...
Dr Chantal Meystre says video appointments enable clients to access a scarce resource on their own terms, and should be here to stay after CovidPsychotherapy over Zoom may not be a panacea, but it has been a boon during Covid-19 lockdowns (Therapy via Zoom should make mental healthcare available for all – it hasn’t, 3 August). I am an integrative psychotherapist and shied away from e-therapy in all forms, as it contravened my idea of the therapeutic frame within which I practised – rich with warmth and empathic relating.With lockdown, I rapidly trained in online etiquette, contracting, indemnity, and safety and security. Zoom security was helpfully improved early in 2020. Could I be therapeutic digitally? Continue reading...
Readers react to a long read on humanist Paul Gilroy, with one saying that discarding the idea of ‘race’ altogether feels rightRe Yohann Koshy’s long read on Paul Gilroy (The last humanist: how Paul Gilroy became the most vital guide to our age of crisis, 5 August), his point that “race is a fiction” and that we should look forward discarding the idea of “race” altogether feels exactly right. The geneticist Adam Rutherford has pointed out that in terms of DNA, racial distinctions by skin colour are meaningless. The sooner we can get to Gilroy’s ideal of “humanism” in a post-racial world, the better.
The answers to today’s counting conundrumEarlier today I set you the following problem about how to count in Ngkolmpu, a language spoken by about 100 people in New Guinea.Ngkolmpu does not have a base ten system like English does. In other words, it doesn’t count in tens, hundreds and thousands. Beyond its different base, however, it behaves very regularly. Continue reading...
DNA suggests body buried in feminine attire with swords had Klinefelter syndrome, researchers sayModern analysis of a 1,000-year-old grave in Finland challenges long-held beliefs about gender roles in ancient societies, and may suggest non-binary people were not only accepted but respected members of their communities, researchers have said.According to a peer-reviewed study in the European Journal of Archaeology, DNA analysis of remains in a late iron age grave at Suontaka Vesitorninmäki in Hattula, southern Finland, may have belonged to a high-status non-binary person.

When I asked other parents, each had noticed a very real preference for their sons. ‘My father-in-law only likes photos that feature our boy,’ one saidBy the time we left the hospital 34 hours after my son, Jules, was born on 14 July, two nurses had commented on the strength of his suck, four friends had written us some version of “Finally, you’ve got your boy!” and even my female obstetrician had commented favorably on the size of his penis. (If you must know, it had to do with the clamp used during his hospital circumcision.)Related: A childhood desire to wear women’s pants has returned.

People don’t listen to outsiders. They need enlightened insiders to offer them a ladder to climb downWhat should we do about people who refuse to get vaccinated, or who continue to deny that Covid is real? Debate on this issue has raged for months in the US. “Respect them!” scolded conservative commentators. “Shame them!” urged some. Others counselled empathy for them as victims of disinformation.But as the surging Delta variant ushers in the “pandemic of the unvaccinated”, uncertainty about persuading pandemic holdouts has given way to anger and despair. This was exemplified by the recent public reaction to a viral news video showing a Louisiana man recovering from a severe Covid-19 infection in a hospital bed, stating that he would still rather have had to be in hospital than accept a vaccine. It was the first time many of us saw the human face of a puzzling phenomenon which healthcare workers have been telling us about since last year: patients denying the realities of the virus even as they lay sick and dying from it.

A rare way to countToday is the International Day of the World’s Indigenous People, which aims to raise awareness of issues concerning indigenous communities. Such as, for example, the survival of their languages. According to the Endangered Languages Project, more than 40 per cent of the world’s 7,000 languages are at risk of extinction.Among the fantastic diversity of the world’s languages is a diversity in counting systems. The following puzzle concerns the number words of Ngkolmpu, a language spoken by about 100 people in New Guinea. (They live in the border area between the Indonesian province of Papua and the country of Papua New Guinea.) Continue reading...

When journalist Jennie Agg suffered four miscarriages, she set out to better understand what is known about why women lose pregnancies and why conversations on the subject are still so difficultIn 2017, Jennie Agg had the first of what would be four miscarriages. Despite being told by medics that losing a pregnancy was incredibly common, she found that there was not a lot of solid information out there about what had actually happened to her.Now more and more high-profile women, including the prime minister’s wife, Carrie Johnson, are deciding to share their own stories of miscarriage. But as Jennie tells Rachel Humphreys, the conversations we have about miscarriage have changed very little over the years. Continue reading...
Exhibition at Fitzwilliam Museum in Cambridge to tell story of little known civilization that flourished from eighth to third century BCWisdom, as Bob Marley put it, is better than gold. From next month however, the precious metal is central to a major new historical exhibition in Cambridge using loaned artefacts telling the story of an ancient civilization little known beyond Kazakhstan.Golden objects unearthed from ancient burial mounds built by the Saka warrior people of central Asia – a culture which flourished from around the eighth century BC to the third century BC – will go on display at the Fitzwilliam Museum.

Discovery that traces of genetic material are all around us opens a non-invasive way to boost biodiversityDNA is in the air – literally. It is wafted around by all the Earth’s creatures, and now scientists have found a way to detect these invisible traces of genetic material so they can identify the animals that released them.The discovery – made independently by British and Danish research groups earlier this year – opens up a powerful way to pinpoint the presence of rare wildlife in deserts, rainforests and other hostile environments.

People from ethnic minorities live longer than white people, but are at greater risk from CovidAlthough our world seems increasingly awash with data, there are still data deserts, leading to gaps in understanding.One big omission is that death registrations in England and Wales do not hold information on ethnicity, but an experimental analysis by the Office for National Statistics linked 2011 census records to 88% of death registrations between 2011 and 2014, with results weighted to deal with limitations in the records. It may be surprising that life expectancy at birth was lower in UK White and Mixed ethnic groups than all other self-reported ethnicities. For example, Black African women had an estimated life expectancy of 89 years (87 to 91 years), around six years more than White and Mixed ethnic women, while for Black men it was around 84 years (83 to 85), longer than most other groups.

Those who attack Neil Ferguson and Sage’s pandemic predictions only expose their ignorance about science• Coronavirus – latest updates• See all our coronavirus coverageIt feels like open season on Professor Neil Ferguson right now. Sections of the media and several columnists delight in castigating the epidemiologist, or “Professor Lockdown”, for being “doomster in chief”, constantly predicting catastrophe and then back-pedalling when the worst numbers don’t materialise.Opponents of Covid restrictions blame Ferguson and his team at Imperial College London for persuading Boris Johnson to shake off his libertarian instincts and take us into lockdown. One presenter on new channel GB News described Ferguson as a “numpty” on air, and the very mention of his name attracts groans in some circles. Continue reading...
Scientists are pinning hopes on elaborate detectors to track the elusive material that holds galaxies togetherDeep underground, scientists are closing in on one of the most elusive targets of modern science: dark matter. In subterranean laboratories in the US and Italy, they have set up huge vats of liquid xenon and lined them with highly sensitive detectors in the hope of spotting subatomic collisions that will reveal the presence of this elusive material.However, researchers acknowledge that the current generation of detectors are reaching the limit of their effectiveness and warn that if they fail to detect dark matter with these types of machines, they could be forced to completely reappraise their understanding of the cosmos.

If the PM’s climate spokesperson is in no rush to go electric, then why should we bother?‘I don’t fancy it just yet,” said Allegra Stratton, the No 10 press secretary turned prime minister’s climate spokesperson, when she was asked about getting an electric car. She preferred her old diesel, thank you.If this was merely the most memorable in a series of suboptimal comments from the person hired to communicate the urgency of Cop26, the climate summit, you couldn’t fault it as a summary of Boris Johnson’s position on decisive climate action. He doesn’t fancy it just yet. Continue reading...
An unexpected friendship was a breath of fresh air after my turbulent city lifeMuch is said about walking the road less travelled. There’s joy in the unexpected and the unravelling of, well, who knows what. Just over a year ago, I left my London life for rural Wales. I saw it as not a desirable but a necessary pause in what had become a turbulent life. The previous six years had been full of turmoil, death, subsequent grief and estrangement. Before my big move, I ran away for a month to New York, to spend time on my own. I spent the days writing and watching a blur of people rotate in the world as I tried to find my place in it. I had become deeply sad.Walking has never been my thing, but there’s no point in being in the countryside if you’re not going to try it out. So I bought a pair of expensive walking boots and made it my goal to put one foot in front of the other. Which is how I came to meet Wilf, a farmer in his 70s. Most days when I would go out I would see him tending to his sheep. It was a wholesome sight, a shepherd with his flock. There was something eternal about it, a man toiling the earth, as if this one scope held all of eternity. It made everything else look so starkly ephemeral. Continue reading...
Trump’s team reportedly believed that coronavirus would hurt Democratic states – and Democratic governors – worse. But the virus does not discriminateSome of the most powerful conservatives in the United States have, since the beginning of the Covid-19 pandemic, chosen to sow disinformation along with mockery and distrust of proven methods of combating the disease, from masks to vaccines to social distancing. Their actions have afflicted the nation as a whole with more disease and death and economic crisis than good leadership aligned with science might have, and, in spite of hundreds of thousands of well-documented deaths and a new surge, they continue. Their malice has become so normal that its real nature is rarely addressed. Call it biological warfare by propaganda.Call Jared Kushner the spiritual heir of the army besieging the city of Caffa on the Black Sea in 1346, which, according to a contemporaneous account, catapulted plague-infected corpses over the city walls. This is sometimes said to be how the Black Death came to Europe, where it would kill tens of millions of people – a third of the European population – over the next 15 years. A Business Insider article from a year ago noted: “Kushner’s coronavirus team shied away from a national strategy, believing that the virus was hitting Democratic states hardest and that they could blame governors.” An administration more committed to saving lives than scoring points could have contained the pandemic rather than made the US the worst-hit nation in the world. Illnesses and casualties could have been far lower, and we could have been better protected against the Delta variant. Continue reading...

Hottest Olympics in history will put pressure on organisers to rethink sport in light of climate crisisOlympic athletes and volunteers in Tokyo are being “tortured” by dangerous heat, meteorologists have said, as the hottest Games in history puts pressure on organisers to rethink the future of sport in a climate-disrupted world.Temperatures hit 34C in the Japanese capital on Thursday with humidity of nearly 70%. Athletes and sports scientists say the combination of heat and moisture has led to “brutal” conditions that must be avoided at future events. Continue reading...

A shutdown would have devastating global impacts and must not be allowed to happen, researchers sayClimate scientists have detected warning signs of the collapse of the Gulf Stream, one of the planet’s main potential tipping points.The research found “an almost complete loss of stability over the last century” of the currents that researchers call the Atlantic meridional overturning circulation (AMOC). The currents are already at their slowest point in at least 1,600 years, but the new analysis shows they may be nearing a shutdown. Continue reading...

Zac Manuel discusses his documentary about a young Covid vaccine trial participant intent on challenging vaccine hesitancy in her communityOur recent release on the Guardian Documentary strand is This Body, a film about a young woman called Sydney Hall who has decided to go against the skeptics and participate in a Covid vaccine trial. A veterinary student, her trust in science and the medical industry is not one shared with most of her community, especially in the echoes of the Tuskegee syphilis experiment alongside contemporary medical inequalities that continue towards Black America to this day.The director, Zac Manuel, is a New Orleans-based film-maker who hopes that telling stories about the Black southern experience and Black legacy through his work will encourage change in society. We asked him a few questions about his latest film. Continue reading...
