Ten mind-bending riddlesUPDATE: The solutions can be read hereDavid Copperfield’s History of Magic is a beautiful new book by the eponymous magician (coauthored with psychologist Richard Wiseman and magician David Britland), which tells the story of magic through objects in his private museum, the largest and most impressive collection of magic memorabilia in the world.The International Museum of the Conjuring Arts is housed in a gigantic building on the outskirts of Las Vegas, the city where Copperfield, aged 65, still performs 15 shows a week. (His industriousness has helped make him the highest grossing solo entertainer of all time.) Continue reading...

People in the Americas and Pacific best placed to view lunar event from start to finishThis week, a full moon occurs on 18-19 November, and for some around the world it will be an “almost total” lunar eclipse. A lunar eclipse occurs at full moon, when the moon travels directly behind the Earth and so crosses through our planet’s shadow. More than 97% of the moon’s disc will be in the darkest part of Earth’s shadow, known as the umbra.The eclipse begins at 6.02 GMT, when the moon’s western limb touches the outer edge of the Earth’s shadow. This edge does not block out all the sunlight, and is known as the penumbra. It produces a subtle dimming effect that is easily overlooked. Contact with the umbra takes place just before 7.19 GMT, and will cause a distinct shadow to begin crossing the lunar disc. The midpoint of the eclipse, the almost total phase, occurs at 9.03 GMT. The moon then leaves the umbra at 10.47 GMT, and the penumbra just before 12.04 GMT. Continue reading...

Exclusive: Oxfordshire-based Emergex gets go-ahead for trials in Switzerland for skin patch vaccine

I was turning 40 and very unfit. Now my super-healthy parents, both in their 70s, have inspired me to exercise and I love itIt’s Saturday morning and I’m standing in the middle of Osterley Park, west London, between my mum and dad, getting ready for the weekly parkrun. My dad is jogging on the spot, my mum is doing the same. I am thinking how do I get out of this? Both of them are full of energy, encouraging me to get warmed up. All I want is a chocolate and nice masala chai – my favourite spicy tea. I hear the countdown, getting nervous now, and off we go. My dad has sped ahead and with his hand he signals to me to keep up. Behind me is my mum. I can’t go anywhere, they are both watching me and I will have to finish this run stuck between them. Finally, we get to the finishing line and I’m shattered. My dad can do a 5km in 33 minutes. I can barely do it in 45. My mum and I walk and run together.Later on my dad will encourage me to do some skipping, and Mum will get me hula-hooping. This, along with their nutritional advice, has been my daily routine for the past six months. Who needs expensive personal trainers when I can turn to Mum and Dad? Continue reading...

Homo sapiens migrated to the continent in waves – but the reasons for their early failures to overcome Neanderthals are a mysteryModern humans made several failed attempts to settle in Europe before eventually taking over the continent. This is the stark conclusion of scientists who have been studying the course of Homo sapiens’s exodus from Africa tens of thousands of years ago.Researchers have recently pinpointed sites in Bulgaria, Romania and the Czech Republic where our ancestors’ remains have been dated as being between 40,000 to 50,000 years old. However, bone analyses have produced genetic profiles that have no match among modern Europeans. Continue reading...

The ability to control our dreams is a skill that more of us are seeking to acquire for sheer pleasure. But if taken seriously, scientists believe it could unlock new secrets of the mindMichelle Carr is frequently plagued by tidal waves in her dreams. What should be a terrifying nightmare, however, can quickly turn into a whimsical adventure – thanks to her ability to control her dreams. She can transform herself into a dolphin and swim into the water. Once, she transformed the wave itself, turning it into a giant snail with a huge shell. “It came right up to me – it was a really beautiful moment.”There’s a thriving online community of people who are now trying to learn how to lucid dream. (A single subreddit devoted to the phenomenon has more than 400,000 members.) Many are simply looking for entertainment. “It’s just so exciting and unbelievable to be in a lucid dream and to witness your mind creating this completely vivid simulation,” says Carr, who is a sleep researcher at the University of Rochester in New York state. Others hope that exercising skills in their dreams will increase their real-life abilities. “A lot of elite athletes use lucid dreams to practise their sport.” Continue reading...

Six well-known public figures take the colour test. Who chose calming blue?The Observer Magazine of 8 March 1970 had a bit of fun with a colour test developed by the psychologist Dr Max Lüscher that supposedly revealed personality and character traits (‘Showing your true colours’), despite his stern warning that ‘it is not a parlour game or a horoscope’.Robert Shields, the Observer’s psychology correspondent, assessed the test and presented a simplified version to try out for yourself. There were eight coloured cards to rank in order of preference. Mine were violet, red, dark blue, green, brown, black, yellow, and grey. I was delighted to find that violet is ‘popular among pre-adolescents, emotionally immature adults and homosexuals’ and showed one’s modus operandi, but the second choice shows what one’s objective really is – for red, ‘excitability, sexual desire, the will to win and the urge to dominate others’. Nailed it. Continue reading...

A recent wave of mistakes shows how misinterpreting data risks misrepresenting the impact of the virusSince we have just had Maths Week in England, it seems appropriate to look at a wave of recent errors when communicating numbers.First, the statistics may be described wrongly. The chief executive of NHS England recently claimed: “We have had 14 times the number of people in hospital with Covid than we saw this time last year”, a claim repeated on Sky News and ITV. But there were fewer Covid-19 patients in England on 4 November (7,201) than a year earlier (11,037). The intended reference was to last August, when there were about 23,000 admissions within two weeks after a positive test, about 14 times higher than last year. Continue reading...

These ‘must-do’ itineraries people feel the need to undertake before they die can come with a heavy costIt was revealed last week that a retired lecturer named Darrell Meekcom had been arrested for indecent exposure and dangerous driving after he mooned a speed camera. It sounds as though he’d managed to perform a contortionist manoeuvre at the wheel but in fact he stopped the car and got out while his wife went to buy some bread. The key detail, though, is that Meekcom is terminally ill, having been diagnosed with multiple system atrophy.The act of baring his bottom to a traffic enforcement camera, Meekcom told the police, was an item on his “bucket list”. “Have you never wanted to moon a speed camera?” he asked one of the arresting officers.

The online star with 15 million subscribers on demystifying everything from black holes to the immune system, the trouble with anti-vaxxers, and what his cancer taught himSkim Philipp Dettmer’s CV and you’d have to say he was an improbable candidate to become one of the world’s foremost science communicators. The 35-year-old from Munich dropped out of high school in Germany aged 15. He eventually did a history degree, and only became involved in science through his interest in infographics. This led, in 2013, to him creating Kurzgesagt (AKA “In a nutshell”), one of the most popular science channels on YouTube. The platform’s irreverent, kaleidoscopic videos – stripped-back guides to everything from black holes to Covid – have more than 15 million subscribers and have clocked up almost 1.5bn views.Dettmer has now written a book about the human immune system, which has intrigued him for more than a decade. Everyone has an opinion on theirs – whether it’s good or not up to much; how best to “boost” it – but it can be a struggle to understand how it works. In Immune: A Journey into the Mysterious System That Keeps You Alive, Dettmer uses eye-catching graphics and simple language to untangle the strange, compelling, sometimes grisly methods our bodies use to defend us from disease.

The machine learning outfit’s foray into pharmaceuticals could be very useful, but its grand claims should be taken with a pinch of saltThe most interesting development of the week had nothing to do with Facebook or even Google losing its appeal against a €2.4bn fine from the European commission for abusing its monopoly of search to the detriment of competitors to its shopping service. The bigger deal was that DeepMind, a London-based offshoot of Google (or, to be precise, its holding company, Alphabet) was moving into the pharmaceutical business via a new company called Isomorphic Labs, the goal of which is grandly described as “reimagining the entire drug discovery process from first principles with an AI-first approach”.Since they’re interested in first principles, let us first clarify that reference to AI. What it means in this context is not anything that is artificially intelligent, but simply machine learning, a technology of which DeepMind is an acknowledged master. AI has become a classic example of Orwellian newspeak adopted by the tech industry to sanitise a data-gobbling, energy-intensive technology that, like most things digital, has both socially useful and dystopian applications.

When photographer Mary Berridge’s son was diagnosed with Asperger’s, she began to see his world in a new light. She set out to capture a series of everyday – and exceptional – stories, one image at a timeI have been immersed in the world of autism since my son was diagnosed with Asperger syndrome. Graham had many of the traits of autism from when he was a baby: speech and motor skill delays, sensory sensitivities, anxiety in big social gatherings and more. He had seen professionals for evaluations, but did not get a diagnosis until he was seven.This was a kid who had meltdowns over the sound of a blowdryer one floor up, the feel of a new shirt and the sight of a slice of cherry pie. Our lowest point was when he started refusing to enter homes he hadn’t been in before, or getting so upset at entering a restaurant that he would throw up. At least now I can sort of laugh when I think of the strangers in the grocery store who would approach him, then a cherubic toddler, and ask what his name was. “Mr Stupid Nobody,” was his reply.

Panel of 200 scientists tells Cop26 Indigenous people, business, governments and scientists must collaborate

Chris Talbot is in favour of compulsory vaccinations for frontline NHS staff, but Karen Jacob fears it could exacerbate a recruitment crisis. Plus letters from Brian Lawrence, Ben Ashford and Dr Simon RobertsFrances Ryan is correct in focusing on the potential risks to vulnerable patients from unvaccinated NHS staff (Mandatory Covid jabs shouldn’t be controversial – NHS staff have a duty to do no harm, 10 November), but there is another, equally compelling argument why unvaccinated staff should not be employed by the NHS.Vaccinations are a vital part of the NHS strategy to contain the spread of a debilitating, and sometimes deadly, virus. To refuse to be vaccinated (hiding behind the more reasonable sounding “exercising my freedom of choice”) is effectively joining the anti-vaxxers, who use the same arguments as those by the NHS vaccine refusers (along the lines of “it’s untested”, “my own immune system works perfectly well”, or “this is the state telling me what to do”).

Billionaires may spend fortunes on trying to cheat death, but there’s a much easier way, writes Paul Martinez. Plus letters from Luce Gilmore, George Baugh and Geoff ReidJohn Harris is surely right to scorn the grotesque sums being spent on “transhumanism” (If the super-rich want to live for ever our planet is truly doomed, 7 November), but not all of us can afford, or want to move into, co-housing or a retirement village. Fortunately, a more practical solution is at hand. Research demonstrates consistently that the three most reliable strategies to live longer and well are learning new things, social interaction and physical exercise. All three are readily available from the u3a, a self-help learning organisation for people who have left full-time work.

Exclusive: Up to six private clinics are offering drug, with health experts fearing a two-tier system of treatmentA growing number of private clinics are offering ketamine for depression, according to experts who warn of a potential “wild west” of providers with no national register of patients’ treatment being integrated into overall NHS care.At least six private providers in the UK offer the drug for depression. In March the first service that also includes psychotherapy opened in Bristol, charging £6,000 for a course of low-dose treatments and talking therapy. Continue reading...

Ferrell is a neurotic patient and Rudd a dangerously narcissistic therapist, in this plodding drama about a real-life scam which is saved by the sheer unbelievability of its source material‘I’m not going to let anyone use you … I’m going to help you and everything’s going to be all right.” There are three types of people in this world. Those who, upon hearing such a pronouncement, cling to it and its utterer like a drowning man to driftwood. Then there are those who would run – fast and far and never looking back. And then, of course, there are those who would say such a thing.In Apple TV+’s The Shrink Next Door, Marty (Will Ferrell) is the first kind – a 40-year-old bundle of borderless neuroses, a manchild in over his head at work and everywhere else. His sister Phyllis (Kathryn Hahn, continuing to prove the notion that everything should have more Kathryn Hahn in it) is the second kind. Tough and sceptical, the only fool she suffers in her life is Marty, and none too gladly. It is she who puts Marty the way of Dr Ike (Paul Rudd), a therapist and the utterer in question. Over the next 30 years, he inveigles his way into Marty’s life, his finances and his home (or at least his summer home in the Hamptons), to the painful incredulity of Phyllis who – as anyone who has witnessed a friend or family member being colonised by a narcissist will know – is powerless to do anything about it, even before she is ostracised from their cult of two.

Bob Caldwell wonders what has happened to our trust in government since the second world war, while Dave Hunter is concerned that current generations are not making sacrifices for future onesMuch has been made of the resemblance between wartime Britain and the current pandemic. Having experienced both, I find the contrast in social reactions to the two situations very striking and puzzling. During the war, nobody denied its existence, nor disputed whether it represented an existential threat; no one refused to enter air raid shelters, nor declined to don a government supplied gas mask. We trusted every restriction, including severe rationing, as having been imposed for our ultimate benefit. What has happened to cause so many to refuse life-saving procedures and flout sensible precautions during this current emergency when the threat has been, and continues to be, equally obvious?

Mice with hind legs paralysed learned to walk again after a single injection of synthetic nanofibresMice with spinal cord injuries that left their hind legs completely paralysed learned to walk again after a single injection of synthetic nanofibres that scientists say could revolutionise treatments for the condition.The therapy is based on designer molecules that mimic the natural environment of the spinal cord and send signals to trigger cells to repair and regenerate. The team behind the work hope to begin patient trials within two years. Continue reading...

Spectrum of reflected light from Kamo`oalewa closely matches lunar rocks from Nasa’s Apollo missionScientists have identified what appears to be a small chunk of the moon that is tracking the Earth’s orbit around the Sun.The asteroid, named Kamo`oalewa, was discovered in 2016 but until now relatively little has been known about it. New observations suggest it could be a fragment from the moon that was thrown into space by an ancient lunar collision. Continue reading...

Climate experts say their message is getting through but more urgent work is needed

Without fungi we don’t have bread, chocolate, cheese, soy sauce, beer or wine. They are also crucial to protecting our climateLet’s picture a dinner with family or friends that began by enjoying beer, wine, fruit juice or maybe a fizzy kombucha beverage. You’re contemplating a glorious basket of bread, wrapped in awe of its perfect crumb and fantasizing about the moment you slather it in butter or olive oil. Then come the fresh vegetables sauteed with soy sauce, maybe tofu or free-range beef with potatoes or rice, followed by cheese, or a chocolate dessert – and to top it off, a lovely cup of coffee or tea with some chocolates or maybe some sake? We need to stop for a moment and thank fungi for all of this. Honestly, none of it would be possible without them, and your dinner would certainly not be so tasty!Fungi are responsible for almost all our food production, and most of our processed materials. They are also to be thanked for many of the important medical breakthroughs in human history that treat both physical and mental ailments, for naturally sequestering and slowly releasing carbon, for optimizing industrial processes, and so much more.

New study shows that deer can catch the virus from people and give it to other deer in overwhelming numbersAs America’s pandemic – for now – seems to be moving into a new phase with national rates in decline from the September peak and vaccines rolling out to children, a new worry has appeared on the horizon: wildlife passing on the virus.A new study shows that deer can catch the coronavirus from people and give it to other deer in overwhelming numbers, the first evidence of animals transmitting the virus in the wild. Similar spillover and transmission could be occurring in certain animal populations around the world, with troubling implications for eradicating the virus and potentially even for the emergence of new variants.

Nasal bone distinguishes herbivore Brighstoneus simmondsi, whose skull was found on the Isle of WightA new species of dinosaur with an extremely large nose has been identified by a retired GP who spent lockdown rummaging through boxes of ancient bones.Jeremy Lockwood, who is studying for a PhD at the University of Portsmouth, set himself the task of cataloguing every iguanodon bone discovered on the Isle of Wight. As he sorted the bones from the collections of the Natural History Museum in London and the Dinosaur Isle museum on the Isle of Wight, he discovered a specimen with a unique “bulbous” nasal bone.

Its gurus increasingly promote vaccine scepticism, conspiracy theories and the myth that ill people have themselves to blame. How did self-care turn so nasty?Ozlem Demirboga Carr is not really into all that woo‑woo stuff. “I’m definitely a full-science kind of person,” says the 41-year-old telecoms worker from Reading. She doesn’t believe in crystals, affirmations or salt lamps. But she did find herself unusually anxious during the UK’s Covid lockdown in March 2020 and, like many people, decided to practise yoga as a way to de-stress.“I tried to be open-minded and I was open to advice on trying to improve my wellbeing and mental health,” she says. So she followed a range of social media accounts, including the “somatic therapist and biz coach” Phoebe Greenacre, known for her yoga videos, and the “women’s empowerment and spiritual mentor” Kelly Vittengl. The Instagram algorithm did its work. “I suddenly found myself following so many wellness accounts,” she says. Continue reading...

Malls, restaurants and arcades in the Philippines capital are packed with children as Covid curbs ease

The Science Weekly podcast is in Glasgow, where we are 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 speaks to environment reporter Oliver Milman about electric cars, ‘environmentally-friendly’ planes and the need to rethink transportYesterday evening, in a surprise press conference, China and the US announced a plan to work together on cutting greenhouse gas emissions in the next decade. The China-US Joint Glasgow Declaration on Enhancing Climate Action detailed some key areas for action, which included cutting methane and reducing emissions from industry and transport.Globally, that last sector accounts for around a quarter of CO2 emissions. And to find out how they – and other countries – might reduce transport’s carbon footprint, Science Weekly’s Madeleine Finlay spoke with environment reporter Oliver Milman. Continue reading...

It is hoped vaccine based on similar technology to Oxford Covid jab can protect against both Zaire and Sudan species of virusThe first jab of a new Ebola vaccine that may protect against multiple species of the virus is to be given on Thursday, researchers have said, with the vaccine based on similar technology to the Oxford Covid jab.Ebola haemorrhagic fever is caused by the Ebola virus and has caused devastation in some parts of the world. It is thought the outbreak in west Africa in 2014-16 may have led to more than 11,000 deaths, while the outbreak in the DRC between August 2018 and June 2020 claimed more than 2,200 lives.

Lawsuit follows similar ones challenging new Biden administration rules for federal contractors and large businessesA coalition of 10 states sued the federal government on Wednesday to try to block a Covid-19 vaccine requirement for healthcare workers, marking a new front in the resistance by Republican-led states to the pandemic policies of President Joe Biden’s administration.The lawsuit filed in a federal court in Missouri contends that the vaccine requirement threatens the jobs of millions of healthcare workers and could “exacerbate an alarming shortage” in healthcare fields, particularly in rural areas where some health workers have been hesitant to get the shots.

Findings of Japanese study back idea that cats retain a mental representation of their ownersIf you’ve ever pondered whether your pet cat gives a whiskers about your whereabouts, research may have an answer: cats appear to track their owners as they move about the house and are surprised if they turn up somewhere they’re not expecting them.The finding supports the idea that cats retain a mental representation of their owners, even when they can’t see them; a crucial bridge to higher cognitive processes such as forward planning and imagination.

Readers express frustration at the prime minister’s recent visit to Hexham hospital, where he failed to wear a face coveringWith regards to Boris Johnson’s trip to Hexham hospital, the website of the Northumbria NHS foundation trust has advice for those wishing to visit (Boris Johnson seen maskless in hospital as cases among MPs rise, 8 November). To paraphrase, visiting should be kept to a minimum, and masks must be worn when entering the hospital.What was so necessary that Johnson, and presumably a large retinue of advisers and security personnel, had to travel from London to the hospital? Was anything concrete achieved or learned from the visit? What was so vital that required a large number of people to walk around the hospital? Continue reading...

Animal thought to have caught coronavirus from owners, but experts say there is no evidence pets can pass it to humans

Only half of children aged 12 and above have been vaccinated, despite vaccine being available for monthsWhen Nia Heard-Garris’s son found out the Covid vaccines were authorized for adults in the US late last year, he was thrilled, then asked, “But what about us? What about kids?”The eight-year-old is finally signed up for his first shot later this week. Even though he’s afraid of needles, he can’t wait to get vaccinated so he can return to a greater semblance of normal kid life – hanging out with his friends, going to school, playing sports – without worrying about getting sick or bringing the virus home.

According to psychologists, ‘ambivalent’ relationships can cause us more stress than being with people we actively dislike. Is it time to let go – or can these friendships be salvaged?Roger and Jim have been friends for more than 30 years. When they were younger they were in a band together, and their friendship was forged over a shared love of music and beer. Even now, despite family commitments on both sides, they manage to catch up every couple of months. “Even though he drives me mad,” says Roger.It is Jim who leaps to Roger’s mind at the mention of toxic friendships. Every time they meet, Roger says, they “tend to have the same conversation”, because Jim never listens to what he says. Continue reading...
