Researchers call on governments to implement national obesity strategy to help stem further rises in preventable cancers

Walking around, then sitting down and holding baby for up to eight minutes seems to be the most effective techniqueRather than stumbling back to bed in the early hours after finally soothing their crying baby, sleep-deprived parents may want to peruse the latest scientific literature on the transport of altricial mammals.In an attempt to help those rendered numb by sleep loss, researchers have conducted a series of experiments to find out which approach to wailing infants settles them the best.

Governments and businesses failing to change fast enough, says United in Science report, as weather gets increasingly extremeThe world’s chances of avoiding the worst ravages of climate breakdown are diminishing rapidly, as we enter “uncharted territory of destruction” through our failure to cut greenhouse gas emissions and take the actions needed to stave off catastrophe, leading scientists have said.Despite intensifying warnings in recent years, governments and businesses have not been changing fast enough, according to the United in Science report published on Tuesday. The consequences are already being seen in increasingly extreme weather around the world, and we are in danger of provoking “tipping points” in the climate system that will mean more rapid and in some cases irreversible shifts.The past seven years were the hottest on record and there is a 48% chance during at least one year in the next five that the annual mean temperature will temporarily be 1.5C higher than the 1850-1900 average.Global mean temperatures are forecast to be between 1.1C and 1.7C higher than pre-industrial levels from 2022-2026, and there is a 93% probability that at least one year in the next five will be warmer than the hottest year on record, 2016.Dips in carbon dioxide emissions during the lockdowns associated with the Covid-19 pandemic were temporary, and carbon dioxide emissions from fossil fuels returned to pre-pandemic levels last year.National pledges on greenhouse gas emissions are insufficient to hold global heating to 1.5C above pre-industrial levels.Climate-related disasters are causing $200m in economic losses a day.Nearly half the planet – 3.3 to 3.6 billion people – are living in areas highly vulnerable to the impacts of the climate crisis, but fewer than half of countries have early warning systems for extreme weather.As global heating increases, “tipping points” in the climate system cannot be ruled out. These include the drying out of the Amazon rainforest, the melting of the ice caps and the weakening of the Atlantic meridional overturning circulation, known as the Gulf stream.By the 2050s, more than 1.6 billion people living in 97 cities will be regularly exposed to three-month average temperatures reaching at least 35C.

Two patients take sharply differing approaches as they attempt to beat life-threatening tumours on their own termsReleased to coincide with World Cancer Research day, Thomas Meadmore’s tricky yet involving documentary follows two Britons going rogue in search of a better quality of treatment. Grant Branton, from Brighton, is a sometime biologist reeling after early tests spotted tumours in his bowels while missing shadows in his bones; Surinder Paul, landed with breast cancer, hopes to avoid a mastectomy by leaning hard into oils, juicing and cravatted energy healers – what oncological voice-of-reason Rob Glynne-Jones calls “quackery”. Both have taken their lives into their own hands, which notionally affords them greater control but also obliges them to take critical decisions – even fashion their own suppositories – on ever-dwindling energy reserves.

As we collectively mark the loss of the longest-serving monarch in British history and all that she represented on a national scale, many people are feeling a much more personal impact. The Guardian’s science editor, Ian Sample, talks to Prof Michael Cholbi about what grief is, how losing a public figure can have such a profound impact on our lives,​​ and why there’s value in grievingArchive: Channel 4 News, BBC News, Sky News Continue reading...

New Shepard rocket fails shortly after launch, but uncrewed capsule jettisons successfullyAn uncrewed rocket belonging to Jeff Bezos’s space company, Blue Origin, failed shortly after launch in Texas on Monday morning, a potential setback for the Amazon founder’s wider ambitions of sending humans into orbit.The malfunction of the New Shepard booster, a type of rocket that is similar to the one Blue Origin has used this year to send three crews of up to six people on suborbital flights, came 1min 4sec after launch and just as the vehicle was reaching its maximum dynamic pressure, known as “max q”.

Dr Susan Howard says psychologists in the 1980s were inspired to challenge the system when treating patients with mental health problemsAs a semi-retired clinical psychologist, I find it depressing that Dr Sanah Ahsan’s article (I’m a psychologist – and I believe we’ve been told devastating lies about mental health, 6 September) should sound so revolutionary. When I trained in the early 1980s, a module entitled “community psychology” was part of the curriculum and addressed the very issues she raises. Like Ahsan, some of us were inspired to challenge the system alongside treating our patients’ mental distress. Unsurprisingly, the module didn’t survive the rise of individualism characterised by the Thatcher years.When, 20 years later, I became a trainer of clinical psychologists, I was surprised and disappointed by how few of my younger colleagues engaged with the impact that structural, socio-economic issues had on our patients’ mental health. The role of clinical psychology had become one of picking up the pieces. Thus we inadvertently reinforced the idea that mental disturbance was the individual’s responsibility. Constraints in our role, with an increasing emphasis on therapeutic work, made it almost impossible to address how structural issues could be ameliorated – for example, by bringing a psychological perspective to community efforts aimed at effecting change.

Research shows Sydney residents devising increasingly sophisticated ways to keep highly intelligent but ‘bloody annoying’ birds out of household waste

This week the brightest objects in the constellation are the planet Saturn and the star Deneb AlgediIt is a great time of the year to search out Capricornus, the sea goat. This constellation was identified a few thousand years BC in Babylonian astronomy as the goat-fish, a hybrid creature with the body and head of a goat and the tail of a fish. In Greek mythology, the constellation is often associated with either Amalthea, who suckled Zeus, or Pan, the shepherd god.This week, the brightest object by far in the constellation is the planet Saturn. The chart shows the image looking south from London at midnight as 12 September becomes 13 September. Compare the brightness of Saturn with the brightest star in Capricornus: Deneb Algedi, just off to the east. Then carefully trace out the constellation. Continue reading...

‘Internet commentary personnel’ told to deluge social media with thoughts on anything from cooking to their personal mood

Doctors hail new era for cancer screening as major research shows effectiveness of Galleri testDoctors have told health services to prepare for a new era of cancer screening after a study found a simple blood test could spot multiple cancer types in patients before they develop clear symptoms.The Pathfinder study offered the blood test to more than 6,600 adults aged 50 and over, and detected dozens of new cases of disease. Many cancers were at an early stage and nearly three-quarters were forms not routinely screened for. Continue reading...

Experts agree on importance of traditions seen after Queen’s death in enabling bereaved to process lossThe death of Queen Elizabeth II has plunged the royal household and much of the country into a period of mourning, with black armbands and flags at half mast. While such traditions may seem far removed from everyday experiences of bereavement, experts say rituals can help us cope with death.“Mourning plays an important role in bereavement because it’s a way of externalising the emotions and thoughts of grief and, through that, incorporating the loss into your life and beginning to heal,” said Dr Lucy Selman, an associate professor in end-of-life care at the University of Bristol and the founding director of Good Grief Festival.

When Christie Watson put on an HRT patch she found herself thinking about sex, all the time. What was going on?I began using HRT patches at 42, after a seemingly catastrophic breakdown that resulted in my climbing into a Sainsbury’s fish-finger freezer. My mental health was horrendous. I felt totally outside my own skin, dissociated, and that I’d lost my sense of self. I told a therapist that I related to Mrs Dalloway, a chronically depressed – and arguably narcissistic and bourgeois – fictional Virginia Woolf character. She suggested that these feelings could all be down to perimenopause, a term I’d only heard of vaguely, in passing, even as a former nurse. Perimenopause, she told me, can be an extremely rocky road, lasting up to a decade before menopause itself.My GP didn’t bat an eyelid at my bizarre symptoms, but offered me low-dose HRT patches and described the side-effects as minimal in most people. Some women experience breast tenderness or feeling sick, or headaches but, she said, this usually settled down. I hoped the patches would lead to fewer perimenopausal symptoms and a balancing out of my mood, some comfort and at least some realism. Continue reading...

Weeks after installing a network of meteor-detecting cameras, the members of Fireballs Aotearoa were granted their dearest wish: a rock that fell to EarthIt looks like a scene from a crime show as a search party in hi-vis jackets walks in formation, heads down, searching the brush for clues. But this group is not looking for evidence of a crime, they are after something harder to find: celestial debris from the formation of our solar system.On 28 August, just before 11pm, an immense bright light was seen streaking across New Zealand’s southern sky, followed by a sonic boom. The spectacle, like a brushstroke of white paint on black ink, was captured by 20 hi-tech cameras across Southland set up for this exact event – a meteor entering the atmosphere above, and hopefully landing in, New Zealand.

Student’s find provides new evidence region may be one of first places early humans settled outside AfricaArchaeologists in Georgia have found a 1.8m-year-old tooth belonging to an early species of human that they say cements the region as the home of one of the earliest prehistoric human settlements in Europe, and possibly anywhere outside Africa.The tooth was discovered near the village of Orozmani, which lies about 60 miles south-west of the Georgian capital, Tbilisi, and is near Dmanisi, where human skulls dated to 1.8m years old were found in the late 1990s and early 2000s.

Results believed to be first compelling evidence that modern humans were cognitively better than NeanderthalsNeanderthals have long been portrayed as our dim-witted, thuggish cousins. Now groundbreaking research has – while not confirmed the stereotype – revealed striking differences in the brain development of modern humans and Neanderthals.The study involved inserting a Neanderthal brain gene into mice, ferrets and “mini brain” structures called organoids, grown in the lab from human stem cells. The experiments revealed that the Neanderthal version of the gene was linked to slower creation of neurons in the brain’s cortex during development, which scientists said could explain superior cognitive abilities in modern humans.

Readers and healthcare professionals respond to Dr Sanah Ahsan’s article which argued that for too long, the dominant mental health narrative has located problems in individuals, and not in social injustice or inequalityLike Dr Sanah Ahsan (I’m a psychologist – and I believe we’ve been told devastating lies about mental health, 6 September), I too work as a clinical psychologist and I see every day the impact of inequality, social injustice and abuse of power on individuals’ mental health (and by association, the mental health of their children, partners, colleagues and acquaintances).For too long, the dominant narrative locates problems in individuals, medicalises them and leaves people feeling helpless, ill and stigmatised. It is as though they are defective, and not positive and resilient enough. This lie affects people from all walks of life, but most severely those who are already disfranchised through poverty and inequality. Continue reading...

Eggs from chickens kept indoors due to bird flu outbreaks could still be labelled free range, raising concerns among UK producersEggs produced in the EU could continue to be labelled as “free range”, even if the birds are not allowed outside, under new proposals.The European Commission has put forward plans for scrapping the time limit on the marketing of eggs as free range if chickens are forced to be housed to reduce the risk of outbreaks of bird flu.

According to a recent study, more than 14% of the world’s population probably has, or has had, tick-borne Lyme disease – an infection that can cause long and debilitating symptoms. That number is set to rise too, as climate and environment changes continue to increase tick populations and distribution.To help prevent some of these cases, pharmaceutical company Pfizer and biotech company Valneva will soon be testing a new vaccine against Lyme disease with 6,000 volunteers across Europe and in the US.Madeleine Finlay speaks to Dr Eoin Healy about what Lyme disease is and how the vaccine works, and hears from a special guest about their own experience of getting ill with the disease.Archive: BBC News, TODAY Continue reading...

This ocean warming controls the rate of climate change, and the effects such as sea level rise are irreversible on human timescalesOver the last 50 years, the oceans have been working in overdrive to slow global warming, absorbing about 40% of our carbon dioxide emissions, and more than 90% of the excess heat trapped in the atmosphere.But as our research published today in Nature Communications has found, some oceans work harder than others.

The 72-year-old from Perth, Scotland, has a rare condition that gives her a heightened sense of smell. Continue reading...

In 2020, scientists found sparkling Peinaleopolynoe on hydothermal vents in the eastern Pacific – and were irresistibly reminded of the king of rock’n’rollNearly 4,000 metres (13,000 feet) underwater in the Pescadero basin in the Gulf of California lie some of the Pacific’s deepest hydrothermal vents – and they’re covered in small iridescent worms. “You’ll see little pink sparkly worms, blue ones, red ones, black ones and white ones,” says Avery Hiley, a graduate researcher at the Scripps Institution of Oceanography in San Diego.These are hungry scale-worms, or Peinaleopolynoe – peinaléos meaning “hungry” or “famished” in Greek – named as such because they were first found clustered around a pile of food that scientists had left experimentally on the deep-sea floor. For years they have been nicknamed “Elvis worms” for their sparkling scales, reminiscent of the sequined jumpsuits worn by Elvis Presley. Continue reading...

Children aged 5-11 will no longer be offered Covid jabs, except those in clinical risk groups, UKHSA confirmsThe decision to reduce the number of children who are offered Covid jabs has prompted outcry from parent groups and academics.The UK Health Security Agency (UKHSA) said children who had not turned five by the end of last month would not be offered a vaccination, in line with advice published by the UK’s Joint Committee on Vaccination and Immunisation (JCVI) in February 2022. UKHSA said the offer of Covid jabs to healthy five to 11-year-olds was always meant to be temporary. Continue reading...

Milder winters could threaten crop yields as plant-eating insects spread northwards and become more voracious, researchers sayAgricultural pests that devour key food crops are advancing northwards in the US and becoming more widespread as the climate hots up, new research warns.The corn earworm (Helicoverpa zea) is considered to be among the most common farm pests in the US, ravaging crops such as maize, cotton, soya and other vegetables. It spends winter underground and is not known to survive in states beyond a latitude of 40 degrees north (which runs from northern California through the midwest to New Jersey), but that is changing as soils warm and it spreads to new areas, according to research led by North Carolina State University.

Society’s understanding of mental health issues locates the problem inside the person – and ignores the politics of their distressWe are living, we’re told, through a “mental health crisis”. Mental health services cannot cope with the explosion of demand over the past two years: 1.6 million people are on waiting lists, while another 8 million need help but can’t even get on these lists. Even children are showing up at A&E in despair, wanting to die.But there is another way to see this crisis – one that doesn’t place it firmly in the realm of the medical system. Doesn’t it make sense that so many of us are suffering? Of course it does: we are living in a traumatising and uncertain world. The climate is breaking down, we’re trying to stay on top of rising living costs, still weighted with grief, contagion and isolation, while revelations about the police murdering women and strip-searching children shatter our faith in those who are supposed to protect us.Dr Sanah Ahsan is a clinical psychologist, poet, writer, presenter and educatorDo you have an opinion on the issues raised in this article?

New Zealand researchers believe the isolated spruce could reveal much about the Southern Ocean, one of the world’s major carbon sinksIt is regarded as the “loneliest tree in the world” but the Sitka spruce on uninhabited Campbell Island has been keeping good company of late – with a team of New Zealand researchers who believe it could help unlock climate change secrets.The nine-metre tall spruce holds the Guinness World Record title for the “remotest tree” on the planet. It is the sole tree on the shrubby, windswept island, 700 kilometres south of New Zealand in the Southern Ocean. It’s the only tree for 222km around; its nearest neighbour grows on the Auckland Islands. Continue reading...

From subatomic particles to human beings, interaction is what shapes realityQuantum theory is perhaps the most successful scientific idea ever. So far, it has never been proved wrong. It is stupendously predictive, it has clarified the structure of the periodic table, the functioning of the sun, the colour of the sky, the nature of chemical bonds, the formation of galaxies and much more. The technologies we have been able to build as a result range from computers to lasers to medical instruments.Yet, a century after its birth, something remains deeply puzzling about quantum theory. Unlike its illustrious predecessor, Newton’s classical mechanics, it does not tell us how physical systems behave. Instead, it confines itself to predicting the probability that a physical system will affect us in one way or another. When an electron is fired from one side of a wall with two holes, for instance, quantum theory tells us where it will end up on the other side, stubbornly saying nothing plausible about which hole it has gone through. It treats any physical system as a black box: if you do this to it now, it will react like that later. What happens in between? The theory simply doesn’t tell us. Continue reading...

In modern Britain, millions of kids grow up learning two languages or more – and experts believe fluidity in language has some surprising advantagesFor many three-year-olds growing up in the UK, it’s challenging enough to learn and master one language, usually English. Yet there’s another rising demographic of young children who are acquiring and absorbing vocabulary from multiple languages before they even start primary school.In 2021 there were around 6 million people with non-British nationality living in the UK, with 9.6m people born abroad – 35% of whom live in London. In the social sciences, this relatively new landscape of such diverse national origins is often referred to as “superdiversity” – a term coined by the German anthropologist Professor Steven Vertovec. The UK’s superdiversity is reflected in our school system, with around 20% of pupils speaking English as an additional language. In London schools, more than 300 different languages are spoken.

Twin academics Perry Zurn and Dani S Bassett fought to forge idiosyncratic paths through academia – then put that knowledge to use in a seven-year study of how we learnIn the early 17th century, there was a room in a house in Copenhagen bursting with hundreds of objects: bones and shells and taxidermised birds, not to mention weapons and rocks and a stuffed polar bear cub hanging from the ceiling. This was the Museum Wormianum, collected and curated by the Danish physician and philosopher Olaus Wormius, or Ole Worm to most. Four hundred years later, this quintessential cabinet of curiosities still inspires philosophy professor Perry Zurn and bioengineering professor Dani S Bassett, identical twins. What provoked Worm to collect? Which electrical signals were firing in his brain? How would the Enlightenment eccentric have behaved given access to Wikipedia?These are questions asked in Zurn and Bassett’s latest work, Curious Minds: The Power of Connection, in which they investigate the neurological, historical, philosophical, and linguistic foundations of curiosity. What exactly is curiosity? Where does it come from and how does it work? In a manuscript peppered with questions, the academics explore everything from Plutarch to Google algorithms, to argue that curiosity is networked. “It works by linking ideas, facts, perceptions, sensations and data points together,” they write in the book, “Yet it also works within human grids of friendship, society and culture.” Continue reading...

Head of US space agency suggests maiden test flight will probably be delayed until the middle of OctoberNasa called off its latest attempt to launch the groundbreaking Artemis 1 moon rocket on Saturday after failing to stem a fuel leak discovered during tanking. It was the second time in five days that technical issues had kept the spacecraft on the launchpad.Mission managers at Kennedy Space Center waited until late in the countdown to scrub the liftoff after the failure of several workarounds to try to plug the leak of liquid hydrogen as it was being pumped into the core stage of the Space Launch System (SLS) rocket.

After moving from South Korea I struggled to fit in. But I began to see a new way of understanding empathy through debatingWhen I moved from South Korea to Australia at the age of eight, I learned the worst part of crossing language lines was adjusting to live conversation – to its rapid, layered rhythms and many about-faces. Once spun out, the best I could do was wait for a topic change or long pause to regain a foothold. Tripping over loose words and broken sentences, I never got far.This was a problem because there were many things I did not understand about my new home – why all public figures (including politicians) presented as sports fans, why strangers were called “mates”, why none of the food was spiced. Unable to ask questions, let alone to raise objections, I began to wear a distant smile and to retreat into the private corners of my mind. Continue reading...
