Your fast food wrappers contain toxic chemicals. Why is that allowed? | Norah MacKendrick
Fast food boxes and wrappers contain toxic chemicals known to interfere with our reproductive systems and contribute to attention and learning disordersIt’s no surprise that fast food is generally bad for your health. But now there’s a new reason to worry: according to a new study out of George Washington University, fast-food containers (such as wrappers used for burgers and burritos) contain toxic chemicals known to interfere with our reproductive systems and contribute to attention and learning disorders. Put simply, our hamburgers and burritos are wrapped in toxic waste.Many convenience foods come with an ingredient list showing consumers what went into the product they’re eating or drinking. Of course, this list doesn’t include the chemicals used to make the box, bag or wrapper encasing the food, or other materials that come into contact with our meal – like the plastic gloves used to handle the sandwich toppings. But these compounds make their way into our food and we ingest them.Norah MacKendrick is an associate professor of sociology at Rutgers University and the author of Better Safe Than Sorry: How Consumers Navigate Everyday Toxics Continue reading...

Terrawatch: Earth’s ‘boring’ plate tectonics period
Curious report suggests calm thousand millennia of ‘Boring Billion’ was more lively than thoughtToday our planet is a lively place: the climate swings from greenhouse to icehouse and back again, while earthquakes, volcanoes, mountain ranges and ocean trenches are all signs of its restless surface. But if you go back far enough, you reach a period where Earth was a very dull place. Nicknamed the “Boring Billion”, the period between 1850m and 850m years ago appears to have had hardly any plate tectonic movement, very little change in climate and a stalling of biological evolution. But was this period more interesting than we think?Geologists have been studying the geochemistry and makeup of continental rocks from the Boring Billion. The geochemistry suggests that the continental crust was hot and thin (40km or less) – not suitable for plate tectonics or building mountain ranges. But curiously the structure and composition of continental rocks indicate that crust did shimmy around and that low mountain ranges existed. The findings are published in Geophysical Research Letters. Continue reading...

Survival rates are generally good, which is largely because of screening, early diagnosis and improved treatment. Continue reading...
Europe’s record summer ‘impossible’ without global heating
Cop26 countries must take action to stop record heat becoming an annual event, say experts
Geert Jan van Oldenborgh obituary
Dutch physicist who helped to identify the links between human-induced climate change and extreme weather disastersGeert Jan van Oldenborgh, who has died aged 59 of multiple myeloma, was co-founder and member of a team of scientists who identified — at speed and while politically a hot topic — the links between human-induced climate change and forest fires, heatwaves, drought, flood and other specific meteorological catastrophes.This is trickier than it sounds. Extreme events have always happened, and for decades most climate scientists were not willing to say that this or that flood or heatwave was directly powered by ever-higher greenhouse gas emissions driven by profligate fossil fuel use. If they did, it was usually long after the event. Continue reading...
Ending Disease review – a powerful case for the miracle cure
In focusing on the stories of recovery this documentary, following patients participating in stem cell research trials in the US, allows the optimism to outshine the controversyHere is a film that tugs at the heartstrings as it painstakingly covers the lives of 10 patients participating in stem cell research trials in the US. From a quadriplegic high-school basketball star to a mother with recurring cancers, the subjects experience remarkable recoveries thanks to this medical revolution. One of the most moving moments is when Ryan, the teenage athlete, returns home four months after his initial treatment and raises his hand to greet his loved ones at the airport, a progress that would have been unimaginable without the advent of stem cell therapy.While the treatment has proved extraordinarily successful in combating incurable diseases, the research remains controversial as it involves the use of human embryos, which is inevitably intertwined with the abortion debate hotly contested in US politics. Furthermore, pharmaceutical corporations are hostile to a medical technology that would significantly reduce the traditional reliance on medications. Indeed, in the case of cancer patients, as stem cells can multiply into healthy cells to repair damaged areas from within, the research aims to reach a point where chemotherapy would no longer be needed. Once banned by George W Bush, federal funding for stem cell studies has gradually increased, though it remains mostly awarded for non-embryonic research. Continue reading...
Cop26 – the world leaders arrive – podcast
The Science Weekly podcast is in Glasgow where we will be bringing listeners daily episodes from Cop26. Each morning you will hear from one of the Guardian’s award-winning environment team. Today, host Madeleine Finlay hears why the Bahamas are under imminent threat from the climate crisis and what Guardian environment reporter Fiona Harvey makes of India’s commitment to be net zero – by 2070.Today the world leaders arrived in Glasgow for Cop26, the critical climate conference. Alarm, anger and a few significant promises featured during speeches made by dozens of world leaders.Host Madeleine Finlay talks to Guardian environment reporter Fiona Harvey who reflected on the tone of the summit, which was set by Boris Johnson, who opened the Cop26 talks with a stark warning that “the anger and impatience of the world will be uncontainable” if the talks fail to get the world on track to avoid disastrous global heating of more than 1.5C. António Guterres, the UN secretary general, noted governments’ lack of progress in cutting planet-heating emissions. There were some significant announcements, too, such as Narendra Modi, prime minister of India, promising that his country would get to net zero emissions by 2070 and Johnson unveiling new climate aid for vulnerable developing countries.

The Guardian view on spooky science: AI needs regulating before it’s too late | Editorial
If by 2052 a computer could match the human brain then we need better ways to build it“Progress in AI is something that will take a while to happen, but [that] doesn’t make it science fiction.” So Stuart Russell, the University of California computing professor, told the Guardian at the weekend. The scientist said researchers had been “spooked” by their own success in the field. Prof Russell, the co-author of the top artificial intelligence (AI) textbook, is giving this year’s BBC’s Reith lectures – which have just begun – and his doubts appear increasingly relevant.With little debate about its downsides, AI is becoming embedded in society. Machines now recommend online videos to watch, perform surgery and send people to jail. The science of AI is a human enterprise that requires social limitations. The risks, however, are not being properly weighed. There are two emerging approaches to AI. The first is to view it in engineering terms, where algorithms are trained on specific tasks. The second presents deeper philosophical questions about the nature of human knowledge. Continue reading...

Flu, cancer, HIV: after Covid success, what next for mRNA vaccines?
The technology was viewed with scepticism before the pandemic but there is now growing confidence about its useIt is one of the most remarkable success stories of the pandemic: the unproven technology that delivered the Moderna and Pfizer/BioNTech vaccines in record time, helping to turn the tide on Covid-19. The vaccines are based on mRNA, the molecule that instructs our cells to make specific proteins. By injecting synthetic mRNA, our cells are turned into on-demand vaccine factories, pumping out any protein we want our immune system to learn to recognise and destroy.Pre-pandemic, the technology was viewed with scepticism – a clever concept, but not guaranteed to deliver. Now there is growing confidence that mRNA vaccines could have far-reaching applications in tackling diseases from flu to malaria. Continue reading...

Can you solve it? The playful genius of Hungarian puzzles
Logic puzzles in three dimensionsUPDATE: To read the solutions click hereWhen it comes to the world of mathematical puzzles, Hungary is a superpower. Not just because of the Rubik’s cube, the iconic toy invented by Ernő Rubik in 1974, but also because of its long history of maths outreach.In 1894, Hungary staged the world’s first maths competition for teenagers, four decades before one was held anywhere else. 1894 also saw the launch of KöMaL, a Hungarian maths journal for secondary school pupils full of problems and tips on how to solve them. Both the competition and the journal have been running continuously since then, with only brief hiatuses during the two world wars. Continue reading...

Cop26: it’s finally here
The Science Weekly podcast is in Glasgow where we will be bringing listeners daily episodes from Cop26. Each morning you will hear from one of the Guardian’s award-winning environment team. Today, environment correspondent Fiona Harvey explains why this climate summit is so criticalFor almost three decades, world governments have met nearly every year to forge a global response to the climate emergency. This year is the 26th iteration, postponed by a year because of the Covid-19 pandemic, and it is being hosted by the UK in Glasgow.Guardian environment correspondent Fiona Harvey tells Science Weekly host Madeleine Finlay why this year’s summit is so critical. Under the landmark Paris agreement, signed in 2015, nations committed to holding global temperature rises to “well below” 2C above pre-industrial levels, while “pursuing efforts” to limit heating to 1.5C. To meet those goals, countries also agreed on non-binding national targets to cut – or in the case of developing countries to curb the growth of – greenhouse gas emissions in the near term, by 2030 in most cases.

The regrets of the unvaccinated: why Covid-bereaved families are speaking out
The majority of those dying of Covid-19 in the UK and the US are have not been vaccinated. Bereaved relatives are telling their stories to try to convince others to get their jabsPhil Valentine was a Tennessee-based conservative talk radio host who was sceptical about the US government’s response to the coronavirus crisis. He was not completely ‘anti-vax’, but he did not think he was vulnerable to Covid and talked on air about his decision not to be vaccinated. He even performed a song called Vaxman, a parody of the Beatles’ Taxman. Shortly after the song was released, he contracted the virus.Before Valentine died, he sent a message to his brother Mark from hospital about his regret. He asked him to tell others to get the vaccine to make amends for the message he had spread on his show. Continue reading...
‘Vax’ chosen as word of the year by Oxford English Dictionary firm
Accolade reflects how use of the short form of ‘vaccine’ rose by 72 times in a year and spread across societyIn a year when talk over the virtual garden fence has focused on whether you have been jabbed, jagged or had both doses yet, and whether it was Pfizer, AstraZeneca or Moderna you were injected with, Oxford Languages has chosen vax as its word of the year.After deciding last year that it was impossible to sum up 2020 in one word, the company that produces the Oxford English Dictionary said the shorthand for vaccine had “injected itself into the bloodstream of the English language” this year during the Covid pandemic.

Saving Us by Katharine Hayhoe review – across the climate crisis divide
A scientist and gifted speaker makes a convincing case for calm, informed discussions in the race to avert catastropheIt’s not an exaggeration to say that Saving Us: A Climate Scientist’s Case for Hope and Healing in a Divided World is one of the more important books about climate change to have been written. Much of the literature to date feeds the appetite of readers who are already interested in the issue, but this book by Katharine Hayhoe, an internationally renowned climate scientist, could result in a massive expansion of interest in the subject.Hayhoe is a gifted public speaker and Saving Us is a follow-up to her terrific Ted Talk in 2018, “The most important thing you can do to fight climate change: talk about it”. It is an entertaining masterclass on the science of communication, which pulls no punches about the threat that humanity faces or the size of the task to avoid catastrophic consequences.

New evidence suggests Vikings – and their mice – beat Portugal to the Azores
Evidence from animal remains shows Norse seafarers settled on the islands centuries before Portuguese explorersThey came from the land of the ice and snow and the midnight sun – but still ended up in some balmy destinations. This is the conclusion of researchers who have discovered evidence to support the idea that the Vikings settled on the clement shores of the Azores several hundred years before the Portuguese arrived in 1427.Given that the Vikings are usually associated with the frozen north, the claim is startling. Nevertheless, it is based on solid science, says a group of international researchers who recently analysed lakebed sediments in the Azores, an archipelago in the mid-Atlantic. Continue reading...
‘It’s mind-boggling’: the complex, and growing, use of medicinal cannabis in Australia
Tens of thousands of people are turning to the drug to treat a range of conditions – but the evidence is patchy and costs can be highWhen Helen was diagnosed with fibromyalgia in her early 40s, her doctor prescribed her a range of opioids. She tried morphine, meperidine and a few others, but none helped ease the constant pain her chronic condition caused.Long before medicinal cannabis was legal in Australia, while Helen was travelling across North America, a doctor at a dispensary suggested she try cannabidiol oil. “He gave me this bottle of tincture and taught me to use one or two drops under my tongue,” Helen says. “My pain decreased dramatically. I was stunned.” Continue reading...
Burn, baby, burn: the new science of metabolism
Losing weight may be tough, but keeping it off, research tells us, is tougher – just not for the reasons you might thinkAs the director of the Energy Metabolism Laboratory at Tufts University, Massachusetts, Susan Roberts has spent much of the past two decades studying ways to fight the obesity epidemic that continues to plague much of the western world.But time and again, Roberts and other obesity experts around the globe have found themselves faced with a recurring problem. While getting overweight individuals to commit to shedding pounds is often relatively straightforward in the short term, preventing them from regaining the lost weight is much more challenging.

Climate experts warn world leaders 1.5C is ‘real science’, not just talking point
Scientists say keeping temperature rises to 1.5C is vital physical threshold for planet that cannot be negotiatedThe 1.5C temperature limit to be discussed by world leaders at critical meetings this weekend is a vital physical threshold for the planet’s climate, and not an arbitrary political construct that can be haggled over, leading climate scientists have warned.World leaders are meeting in Rome and Glasgow over the next four days to thrash out a common approach aimed at holding global temperature rises to 1.5C above pre-industrial levels, the lower of two limits set out in the 2015 Paris climate agreement.

Honeybees use social distancing when mites threaten hives – study
Foraging bees keep away from centre of colony when infested with mites, find researchersIn the past 18 months humans have become all too familiar with the term “social distancing”. But it turns out we are not the only ones to give our peers a wide berth when our health may be at risk: research suggests honeybees do it too.Scientists have found that when a hive of honeybees is under threat from the mite Varroa destructor – a parasite linked to the collapse of honeybee colonies – the bees respond by changing the way they interact with one another.

How does Covid end? The world is watching the UK to find out | Laura Spinney
The virus won’t disappear – it will just become endemic. But it could still put pressure on health systems in years to comeAs Cop26 gets under way in Glasgow this weekend, one collective action problem is taking centre stage against the backdrop of another. Covid-19 has been described as a dress rehearsal for our ability to solve the bigger problem of the climate crisis, so it seems important to point out that the pandemic isn’t over. Instead, joined-up thinking has become more important than ever for solving the problem of Covid-19.The endgame has been obvious for a while: rather than getting rid of Covid-19 entirely, countries will get used to it. The technical word for a disease that we’re obliged to host indefinitely is “endemic”. It means that the disease-causing agent – the Sars-CoV-2 virus in this case – is always circulating in the population, causing periodic but more-or-less predictable disease outbreaks. No country has entered the calmer waters of endemicity yet; we’re all still on the white-knuckle ride of the pandemic phase.Laura Spinney is a science journalist and the author of Pale Rider: The Spanish Flu of 1918 and How it Changed the World Continue reading...

Abdul Qadeer Khan obituary
Physicist hailed as the father of Pakistan’s atomic weapons industry who confessed to smuggling nuclear secretsThe father of Pakistan’s atomic weapons industry and the greatest proliferator of nuclear weapons in history, Abdul Qadeer Khan, who has died aged 85 after testing positive for Covid-19, was heralded as a hero in his native country, but he left a troubling legacy for the west. Along with Pakistan, the states of Libya, North Korea and Iran all benefited from the nuclear physicist’s dealings. His story is also deeply connected with the travails of neighbouring Afghanistan.There are two basic paths to make the material that provides the explosive power of a nuclear weapons. The first is to process plutonium. The second is to use high-speed centrifuges to enrich uranium to weapons-grade material, called highly enriched uranium (HEU). Continue reading...

‘Rare find’: amphitheatre dig in Kent paints picture of Roman town
Finds at Richborough include skeleton of cat nicknamed Maxipus and potential evidence of figurative arena panelsA big night out for the people of the Roman settlement at Richborough on the Kent coast about 2,000 years ago might have involved gladiatorial contests, wild beast hunting or the occasional execution of a criminal.Taking place in a vast amphitheatre, seating up to 5,000 people, on the western edge of the settlement, such an event was a “special occasion, drawing people from Richborough town and its surrounds”, said Paul Pattison, a senior properties historian at English Heritage. “These were public spectacles, the equivalent of going to a big blockbuster film, in our terms.” Continue reading...
‘I’m scared I’ve left it too late to have kids’: the men haunted by their biological clocks
It’s certainly not just women who worry about ageing and procreation – and now men have begun speaking about their own deep anxietiesIt was when Connor woke up in the middle of the night to go to the bathroom that he started thinking about it. The 38-year-old civil servant from London got back into bed and couldn’t sleep: he was spiralling. “I thought: ‘Shit, I might not be able to have children. It actually might not happen,’” he says.“It started with me thinking about how I’m looking to buy a house, and everything is happening too late in my life,” Connor says. “Then I started worrying about how long it would take me to save again to get married, after I buy the house. I was doing the maths on that – when will I be able to afford to be married, own a house and start having kids? Probably in my 40s. Then I started freaking out about what the quality of my sperm will be like by then. What if something’s wrong with the child? And then I thought, oh no, what if me and my girlfriend don’t work out? I’ll be in an even worse scenario in a few years.” Continue reading...
DNA from Sitting Bull’s hair confirms US man is his great-grandson
Study is the first time DNA from a long-dead person was used to demonstrate a familial link between a living individual and a historical figureA sample of Sitting Bull’s hair has helped scientists confirm that a South Dakota man is the famed 19th-century Native American leader’s great-grandson using a new method to analyse family lineages with DNA fragments from long-dead people.Researchers said on Wednesday that DNA extracted from the hair, which had been stored at the Smithsonian Institution in Washington, confirmed the familial relationship between Sitting Bull, who died in 1890, and Ernie LaPointe, 73, of Lead, South Dakota.

Universe review – Brian Cox’s trip to the stars is sheer cosmic cowardice
As the professor guides us through the solar system via excessive CGI and poetic chat, you can’t help but think his latest quest would be more effective if it wasn’t so dumbed downI don’t know how you make an hour-long programme that takes you slowly through 14bn years of history, but the BBC and Prof Brian Cox have done it with the first episode of Universe. Possibly it is a space-time paradox that only the good professor himself could solve. (Please do not write in if I deployed the phrase “space-time paradox” incorrectly. I am an arts graduate who begins this series not entirely sure whether solar systems are bigger than galaxies, and needs this programme very much, even if I cannot honestly say I enjoy it.)The four-part BBC Two series, as you have probably guessed from the title, will eventually deal with just about everything astrophysical. But the opener is all about stars – especially our big yin, the sun. It is pegged to Nasa’s Parker solar probe’s mission, though mentions of this are brief bookends. In between, Cox does his thing.
