Weep, O mine eyes at a lack of manly tears | Brief letters
Men in tears | Resilience | Supper | Olympic winners | Spelling namesAn excellent article by Adrian Chiles (Have you cried with despair in public? There is nothing braver or better, 28 July). In medieval France, it was considered very manly to weep copiously about one’s fallen comrades. If you didn’t cry, what was wrong with you? Didn’t you care? Crying is an effective and natural way of releasing tension.

Three Americans create enough carbon emissions to kill one person, study finds
The analysis draws on public health studies that conclude that for every 4,434 metric tons of CO produced, one person globally will dieThe lifestyles of around three average Americans will create enough planet-heating emissions to kill one person, and the emissions from a single coal-fired power plant are likely to result in more than 900 deaths, according to the first analysis to calculate the mortal cost of carbon emissions.The new research builds upon what is known as the “social cost of carbon”, a monetary figure placed upon the damage caused by each ton of carbon dioxide emissions, by assigning an expected death toll from the emissions that cause the climate crisis.

Nasa’s InSight lander reveals internal structure of Mars
Analysis of marsquakes captured since probe landed in 2018 shows the Martian crust is between 12 and 23 miles thickNasa’s InSight lander has revealed the depth of Mars’s crust and the size of its central core by using data from dozens of marsquakes captured since the probe landed in 2018.The Seismic Experiment for Interior Structure (SEIS) is a dome-shaped instrument that sits on the surface of Mars and can pick up seismic events hundreds or even thousands of miles away. Since its deployment, the mission has recorded 733 distinct marsquakes, about 35 of which were used for the current work. All quakes registered between magnitudes 3 and 4. Continue reading...
Testosterone in women’s athletics - podcast
Genetic advantages in sport tend to be celebrated, but that isn’t always the case when it comes to women’s athletics. At the start of July, two female runners from Namibia, Christine Mboma and Beatrice Masilingi, were told they couldn’t compete in the 400m race in the Tokyo 2020 Olympics unless they reduced their naturally high testosterone hormone levels. Shivani Dave speaks to Katrina Karkazis, a professor of sexuality, women’s, and gender studies, specialising in ‘sex testing’ and sport regulations, about the rules that ban female athletes with naturally high testosterone Continue reading...
Extreme weather will be the norm and UK is not prepared, scientists warn

Genetic engineering test with mosquitoes ‘may be game changer’ in eliminating malaria
UK scientist says gene-drive study rendering female insects infertile may lead to ‘self destruct mosquito’ field tests within 10 yearsScientists have successfully wiped out a population of malaria-transmitting mosquitoes by using a radical form of genetic engineering to render the females infertile – in the most advanced and largest ever test of use of the technology to fight the disease.As well as bringing fresh hope in the fight against one of the world’s biggest killers, the study lays the foundations for further trials of gene-drive technology, which could mean self-destroying mosquitoes being released into the wild within 10 years.

Richard Lewontin obituary
Pioneering biologist and geneticist whose research showed the emptiness of traditional biological concepts of raceThe American scientist Richard Lewontin, who has died aged 92, was intimately involved in some of the most important discoveries, and feuds, of evolutionary biology during the decades in which it passed from knowing that genes existed to specifying them in precise molecular terms.His greatest contribution came in the 1960s, when he demonstrated the existence of very widespread genetic variation within species as well as between them. This research, with John Hubby at the University of Chicago, which had started with grinding up fruit flies, was extended to human beings in a paper published in 1972 that revealed the emptiness of traditional biological concepts of race.

Are Covid jabs ‘Trump vaccines’? No, but I’ll call them that if it means people will take them | Arwa Mahdawi
Trump sycophant Sarah Huckabee Sanders says the ex-president deserves credit for the jab rollout. If that’s the price of herd immunity, so be itForget Pfizer or AstraZeneca, the hottest shot this summer is the Trump vaccine. Hang on, you might cry: there is no such thing. Well, Donald Trump’s former White House press secretary Sarah Huckabee Sanders – a woman who has always had an unusual relationship with facts – begs to differ. Sanders is running for governor of Arkansas, a state with one of the lowest Covid vaccination rates in the US. She seems to want to change that: on Sunday, she published a column explaining her reasons for getting “the Trump vaccine” and arguing that Covid vaccines are safe and effective.Are you wondering whether Sanders, a Trump sycophant, has turned over a new leaf? Is it possible she suddenly cares more about the public good than political gain? I’m afraid not. Sanders, you see, wasn’t content with using her platform simply to encourage her fellow Arkansans to get vaccinated; she also took numerous jabs at Democrats. The reason some people are scared that vaccines are not safe, according to Sanders, is Joe Biden and Kamala Harris’s fault. If “the left truly care about increasing the vaccination rate … they should admit they were wrong to cast doubt on Operation Warp Speed and give President Trump and his team the credit they are due,” Sanders wrote.

The incredible true story of the cancer patient who didn’t have cancer | Ranjana Srivastava
People deserve better than a never-ending stream of unproven practices dangled before them in the guise of hopeTen years ago a desperate young woman walked into my office and declared: “I need your help. I am dying of cancer.”Her story was incredible. At an integrative medicine seminar she had won a special blood test as a door prize. Thinking of having some bloods done anyway, she had taken advantage of the free offer, only to receive a call telling her she had cancer. It was only after an expensive course of intravenous vitamins that her sceptical cousin asked why no one had at least ordered a CT scan to find the cancer. She convinced her GP to order the scan, which detected two tiny lung nodules. The GP sent her to a surgeon who ordered a different scan, by which time the benign nodules had disappeared. The surgeon told her she did not have cancer but she did not believe him. Then she saw me. Continue reading...
A third of middle-aged UK adults have at least two chronic health issues – study
Childhood poverty and health issues before adulthood all factors in decline in mid-life wellbeingMore than one in three middle-aged British adults are suffering from at least two chronic health conditions, including recurrent back problems, poor mental health, high blood pressure, diabetes and high-risk drinking, according to research that warned that health in midlife is on the decline.The study of “generation X” adults born in 1970 found that those who grew up in poorer families were 43% more likely to have multiple long-term health conditions than their peers from wealthier households. Those who had been overweight or obese as children, who had lower birthweight and who had experienced mental ill-health as teenagers were also at increased risk of poor health in midlife.

Don’t blame men for the climate crisis – we should point the finger at corporations | Arwa Mahdawi
Male spending – on petrol and meat – is apparently worse for the environment than women’s. But it’s the system, not individuals, that needs to changeSorry, boys, but it’s all your fault. Melting ice caps, flash floods, rising sea levels: men are to blame for the lot of it. Please don’t drown the messenger, I’m just relaying the results of a Swedish study that found that men’s spending habits cause 16% more climate-heating emissions than women’s. The biggest difference seems to be that men spend more money on petrol. Another big difference: the men surveyed bought more meat than women. So this is the way the world ends, eh? Not with a bang, but with blokes eating too many burgers.I don’t know how many studies published in the Journal of Industrial Ecology go viral, but this paper has had an enormous amount of traction. Of course, this is largely because its findings leant themselves to delicious clickbait such as Men Are Worse for Climate Change Than Women Because They Love Meat and Cars. To be fair, the study didn’t lean into gender war territory in the way you would expect based on the headlines it generated. Gender wasn’t even mentioned in the paper’s title, which was “Shifting expenditure on food, holidays, and furnishings could lower greenhouse gas emissions by almost 40%”. Continue reading...

‘Record-shattering’ heat becoming much more likely, says climate study
More heatwaves even worse than those seen recently in north-west of America forecast in research“Record-shattering” heatwaves, even worse than the one that recently hit north-west America, are set to become much more likely in future, according to research. The study is a stark new warning on the rapidly escalating risks the climate emergency poses to lives.The shocking temperature extremes suffered in the Pacific north-west and in Australia 2019-2020 were “exactly what we are talking about”, said the scientists. But they said the world had yet to see anything close to the worst impacts possible, even under the global heating that had already happened. Continue reading...
Has England reached a peak in Covid infections? | Graham Medley
The trajectory of the pandemic might look more like a range of hills rather than a single mountainWhile the government’s decision to remove most lockdown measures in England was widely expected to result in a large wave of infection and disease, the number of new cases of Covid-19 has been falling over the last five days. Many hope this could mean that we’re past the peak. Yet the reality is more complicated. This is the first time an epidemic has taken place in a highly vaccinated population without control measures in place, so we are in uncharted territory. There is considerable uncertainty about what the next two months hold.The big questions are how high the current wave will get and how long it will last. The number of people in hospital and dying of Covid-19 is directly linked to the number of infections. It’s impossible to accurately predict when we’ll reach the peak of infections, or how long it will take to come back down from this (if I had a pound for every time I’m asked “are we there yet?”, I’d be able to give away a lot of money).

Stop calling people ‘toxic’. Here’s why | Hannah Baer
Believing others have fixed traits which don’t change yields defensiveness, failure to listen, and failure to set boundariesOver the past few years I’ve noticed a rise in the label “toxic” as a response to difficult or destructive behavior. Media outlets from Psychology Today to Harvard Business Review run articles on how to identify or avoid toxic people. Politicians like Mitch McConnell use the term to describe their adversaries. Even academic psychologists have begun to take up the language.Related: It’s time to rethink what loneliness is | Miriam Kirmayer Continue reading...
Can you solve it? Clueless sudoku
Puzzles where less is moreUPDATE: Solutions now available here.Sudoku is an extremely elegant puzzle, and this crucial to its appeal. The rules are simple to understand and the grid – with given numbers usually presented in a symmetric pattern – is striking. Yet perhaps Sudoku is not elegant enough. Perhaps the numbers on the starting grid are an unforgivable blemish, a needless sullying of the page.Or so argue a group of mathematicians, who have come up with a new puzzle genre: ‘clueless Sudoku’, which are Sudoku-style puzzles with a pristine starting grid. These puzzles literally don’t have a (numerical) clue. Continue reading...

Starwatch: watch out for a man holding a snake
Now is the chance to find Ophiuchus, which some view as the 13th sign of the zodiacThis time of year offers the opportunity to track down the large but faint constellation of Ophiuchus, the serpent bearer – literally a man holding a snake. One of the original 48 constellations listed by Ptolemy in the second century, there is no definitive association between the constellation and a myth, but several have been suggested. It could be Apollo grappling with the serpent that guarded the oracle of Delphi; or Apollo’s son Asclepius, who witnessed one serpent heal another by feeding it herbs; or maybe Laocoön, who was slain by sea serpents after he tried to warn the Trojans that the famous horse was a trap.

Dietary supplements causing severe liver injuries in Australians, with some requiring transplants, study shows
Researchers say cases linked to products claiming to promote muscle growth or weight loss are rising and more rigorous oversight is neededThe number of patients being admitted to hospital with severe liver injuries caused by herbal and dietary supplements claiming to promote muscle growth or weight loss is increasing, with some people harmed so severely they required a liver transplant.A study led by Dr Emily Nash from the Royal Prince Alfred hospital examined hospital records of 184 adults admitted to the AW Morrow Gastroenterology and Liver Centre with drug-induced liver injury between 2009 and 2020. She and her co-authors found liver injury cases linked to herbal and dietary supplements increased from two out of 11 patients (15%) during 2009–11, to 10 out of 19 patients (47%) during 2018–20.

Sir Dai Rees obituary
Visionary biochemist who was appointed head of the Medical Research Council in 1987As its head from the late 1980s, the research scientist Sir Dai Rees, who has died aged 85, revolutionised the way the Medical Research Council (MRC) interacted with industry. In this respect, he was a visionary: he understood the importance of a successful interface between basic research and industry, including its impact on attracting public funds.Under his leadership, centres were established with strong industrial links, with the aim of encouraging the practical application of MRC research and inventions. The work of these centres contributed to the development of the “blockbuster” Keytruda antibody for cancer treatment, and of the world’s top-selling pharmaceutical drug, the antibody Humira, which treats rheumatoid arthritis and Crohn’s disease.

Dinah Murray obituary
Champion of autistic people who explored the attention that they devote to a leading interestDinah Murray, who has died aged 75 of pancreatic cancer, was a key figure in autism studies, and an indefatigable advocate for autistic people for three decades. Her acute insight lay in the importance of attention and interests to an understanding of the condition.On the autistic spectrum herself and fascinated with language and the mind, in 1991 Murray read Uta Frith’s book Autism: Explaining the Enigma. She had a eureka moment when it spoke of an autistic person’s attention “going to their leading interest”. Continue reading...
How Islam conquered my mother’s fear of cats
She’d always found them evil and scary, but when I wanted a cat in lockdown I appealed to my mum’s faithCats are perfect to most people, but not to my 42-year-old mother. She is just like any of my 17-year-old friends’ parents – she is spirited, sparky, generous and can be feisty when she needs to be. She cooks arguably the best chicken parmesan in the world, and also has impeccable taste in Bollywood music. But there is one annoying trait that makes her different from the other mothers – she unequivocally loathes all animals, unless they are in a palatable format, like her chicken parmesan.In Britain, a hatred for pets is unheard of, any bitterness towards animals is considered completely unacceptable. After all, we are considered a zoophilist nation. Throughout lockdown, pet ownership has surged. According to statistics from the Pet Food Manufacturers’ Association, there are now 34m pets in the UK including 12m cats and 12m dogs, along with 3.2m small mammals, such as guinea pigs and hamsters, 3m birds and 1.5m reptiles.

The insect apocalypse: ‘Our world will grind to a halt without them’
Insects have declined by 75% in the past 50 years – and the consequences may soon be catastrophic. Biologist Dave Goulson reveals the vital services they performI have been fascinated by insects all my life. One of my earliest memories is of finding, at the age of five or six, some stripy yellow-and-black caterpillars feeding on weeds in the school playground. I put them in my empty lunchbox, and took them home. Eventually they transformed into handsome magenta and black moths. This seemed like magic to me – and still does. I was hooked.In pursuit of insects I have travelled the world, from the deserts of Patagonia to the icy peaks of Fjordland in New Zealand and the forested mountains of Bhutan. I have watched clouds of birdwing butterflies sipping minerals from the banks of a river in Borneo, and thousands of fireflies flashing in synchrony at night in the swamps of Thailand. At home in my garden in Sussex I have spent countless hours watching grasshoppers court a mate and see off rivals, earwigs tend their young, ants milk honeydew from aphids, and leaf-cutter bees snip leaves to line their nests.

Plans of four G20 states are threat to global climate pledge, warn scientists
‘Disastrous’ energy policies of China, Russia, Brazil and Australia could stoke 5C rise in temperatures if adopted by the rest of the worldA key group of leading G20 nations is committed to climate targets that would lead to disastrous global warming, scientists have warned. They say China, Russia, Brazil and Australia all have energy policies associated with 5C rises in atmospheric temperatures, a heating hike that would bring devastation to much of the planet.The analysis, by the peer-reviewed group Paris Equity Check, raises serious worries about the prospects of key climate agreements being achieved at the Cop26 summit in Glasgow in three months. The conference – rated as one of the most important climate summits ever staged – will attempt to hammer out policies to hold global heating to 1.5C by agreeing on a global policy for ending net emissions of greenhouse gases by 2050.

Space-sized egos, tiny tax bills… Billionaires should be jettisoned | Eva Wiseman
The new space race between the world’s richest men proves one thing to the rest of us – the sooner they leave this planet the betterThe time has come to abolish billionaires. I mean, it’s been coming for a while, but now the alarm is ringing.It started ringing when it first became clear that the existence of billionaires revealed a huge failure in our economic system. When it first became clear where wealth comes from, a combination of inheritance, corruption and exploitation. When the benefits of billionaires, who have often been believed to helpfully provide a trickle-down of cash to the rest of us ordinaries, were revealed to be at best minimal and at worst devastating, as their tax avoidance fatally impacts education and healthcare. In June, ProPublica reported that American billionaires essentially pay no taxes – they didn’t break the rules; the rules were broken already. And in this way wealth begets wealth – a millionaire can become a billionaire by simply sitting very still. Continue reading...
I struggled with office life. Now others are alive to benefits of remote working
People with invisible disabilities have long asked for flexible options such as working from home. Then came the pandemicI struggle with a mild form of face blindness, or prosopagnosia. The condition, usually associated with autism, makes it difficult to remember people’s faces. This means that, in high-stress situations, I am often unable to match someone’s face to their name or even remember if I’ve met them before. When I worked at an office, I inadvertently offended colleagues who did not understand why I struggled to place who they were.This is just one way that the daily office environment made my career difficult to navigate. Working from home, as I have for the past three years, has made a positive difference in my ability to be a successful, confident journalist, and a happier person overall. Continue reading...
