Study indicates infants as young as six months old may realise certain words are related – and that interaction with adults boosts understandingBabies as young as six months old may have an inkling that certain words and concepts are related to each other, say scientists in research that sheds new light on how infants learn.The study also found that babies who were more often exposed to adults talking to them about items in their vicinity did better at identifying a picture of an object when the item was said out loud.

Astronomers have named interstellar asteroid ’Oumuamua and found it to be rich in organic moleculesAstronomers are now certain that the mysterious object detected hurtling past our sun last month is indeed from another solar system. They have named it 1I/2017 U1(’Oumuamua) and believe it could be one of 10,000 others lurking undetected in our cosmic neighbourhood.The certainty of its extraterrestrial origin comes from an analysis that shows its orbit is almost impossible to achieve from within our solar system.

The solution to today’s puzzleOn my puzzle blog earlier today I set you the following puzzle:You and your two friends Pip and Blossom are captured by an evil gang of logicians. In order to gain your freedom, the gang’s chief, Kurt, sets you this fearsome challenge. The three of you are put in adjacent cells. In each cell is a quantity of apples. Each of you can count the number of apples in your own cell, but not in anyone else’s. You are told that each cell has at least one apple, and at most nine apples, and no two cells have the same number of apples. Continue reading...

Life-size prints of hundreds of plant specimens collected by the British naturalist come together in FlorilegiumThe publishing deadline was missed by more than 200 years, but finally the work of one of the great men of the Enlightenment has been printed and distributed, sharing with the world the detailed botanical work of Joseph Banks on his journey aboard James Cook’s Endeavour.Cook’s mission when he left England in 1768 was ostensibly to chart the transit of Venus – a measurement that would allow the estimation of the distance from the Earth to the sun, which would aid navigation. However, Cook had been instructed to attempt the “discovery of the southern continent so often mentioned”. Continue reading...

As well as polluting our seas with microplastics, the devilish dandruff turns up all over my house and about my person – I applaud those schools banning itWhat will the rocks record about the lives we lead? What might a future palaeontologist, human or otherwise, make of the structures that will come to signify these moments in which you and I live our lives? They will notice extinctions, of course. Fossils of mammals’ tusks and horns will abound in the rocks, only to disappear when we humans turn up. They will come across our mines – enormous trace fossils, perhaps the largest ever to have existed. They will see, by studying fossil pollen, that the climate changed. They will find our discarded KFC bones and they will wonder how the world supported so many chickens. And there, among it all, they will probably find that most awful of human inventions: glitter. Oodles of it – purples, pinks and reds – crushed into rocks the world over. Mineralised madness. Our lowest ebb. What will those future palaeontologists make of it? What will glitter say about us?Perhaps this is our mark in the geological strata. A post-glitter epoch that all started with a handful of nurseries Continue reading...

Playing Thatcher? Dab on Bluebell. Got a part in Hairspray? Reach for the Madame Rochas. We lift the lid on how actors use smells – from the finest fragrances to cheap tinned mackerel – to nail a roleBefore I go on stage, says Michael Ball, I ask myself a question: “Do I smell nice for all the ladies and gentlemen?” The actor chooses a signature scent for each of his roles, from bay rum for the vengeful barber Sweeney Todd to his mum’s favourite Madame Rochas for Hairspray’s Edna Turnblad.Ball’s not alone in deploying scent to to get beneath a character’s skin. Anne-Marie Duff has a fragrance for each role too. “If ever I smell that perfume on somebody else,” she has said, “it will remind me of a story I’ve told.” Nikki Amuka-Bird, meanwhile, says she “uses aromatherapy oils – lavender for characters with a slow tempo, ylang ylang for sensuous characters”.

Many of the body’s cells regenerate - but not the brain’s, explains Daniel GlaserWe are being treated to a spectacular display of autumn colour this year, but it isn’t only trees that share this pattern for periodic shedding and regrowth. Our own skin cells, for example, are renewed every month or so, but we replenish less than 10% of our bone each year. Certain types of human cells do not seem to regenerate at all and this includes brain cells. With a few exceptions (such as the hippocampus), we are born with all the brain we’ll ever have. Over childhood and into adolescence, extensive pruning of the connections between cells takes place. This neural topiary shapes all the systems of the brain. But once into adulthood, although some new connections are formed, the main structural change is the steady death of our brain cells.Many aspects of life cause our cells to die off, including trauma, drug use, environmental pollutants, strokes… and that’s before we start on age-related diseases such as Alzheimer’s. Yet the quality of our brain function doesn’t decline for most of adulthood. Maybe as our cells decrease we learn to adapt, picking up tricks to help us to make the best of what we’ve got.

The writer, actor and comedian on the joys of cheap restaurants, Otto Dix and that single seat under the stairs on London busesBorn in Anfield, Liverpool, Alexei Sayle studied art before training to be a further-education teacher. When London’s Comedy Store opened in 1979, he became its first MC and, over the following decade, became a central figure in the alternative comedy movement. He has starred in a number of TV shows including The Young Ones (1982-4) and the Emmy-winning Alexei Sayle’s Stuff (1988-1991). His credits also include theatre (The Tempest, Old Vic, 1988), film (Indiana Jones and the Last Crusade, 1989) and radio (the award-winning Alexei Sayle and the Fish People). His book Alexei Sayle’s Imaginary Sandwich Bar is out now, while the second series of his BBC radio programme of the same name is broadcast on weekdays on Radio 4. Continue reading...

She looks at Cliff, then asks Michael if he’s ever been to Sweden. Continue reading...

Mapping the genomes of our ancestors has allowed scientists to uncover secrets and discover new mysteries in our evolutionScientists made a remarkable discovery at Trou Al’Wesse in Belgium earlier this year. Inside a cave that overlooks the Hoyoux river they found clear evidence it had been occupied by Neanderthals tens of thousands of years ago. Yet the cave contained no skull fragments, no teeth – nor any other skeletal remains of this extinct species of human being.The team, from the Max Planck Institute for Evolutionary Anthropology in Leipzig, were sure of their ground, however. Their genetic analysis of soil samples, scraped from the cave floor, had pinpointed the presence of Neanderthals through that most definitive of biological markers: their DNA. Continue reading...

Scientists say number of severe quakes is likely to rise strongly next year because of a periodic slowing of the Earth’s rotationScientists have warned there could be a big increase in numbers of devastating earthquakes around the world next year. They believe variations in the speed of Earth’s rotation could trigger intense seismic activity, particularly in heavily populated tropical regions.Although such fluctuations in rotation are small – changing the length of the day by a millisecond – they could still be implicated in the release of vast amounts of underground energy, it is argued.

Predators hunt out their victims, like pigs sniffing out truffles. Knowing what narcissistic behaviour to look out for can preempt dangerTwenty people have now made allegations of inappropriate behaviour against Kevin Spacey, the majority from his time as the Old Vic’s artistic director. Fourteen of the allegations are so serious that complainants have been advised to go to the police.Managers at the Old Vic say they are sorry they did not create an environment in which people felt they could speak out if they were receiving unwanted attention. This failure has been put down to a “cult of personality” around the actor. Continue reading...

Night after night, elaborately crazy stories plant themselves in your mind through no choice of your own. Don’t tell me something intriguing isn’t going onWhat are dreams for? It’s one of those bottomless questions where the answer tells you mainly about the person doing the answering. Those who pride themselves on being hard-headed and scientific will say they’re meaningless nonsense or, at best, some kind of boring but essential process for consolidating the memories of the day. Those who think of themselves as spiritual, meanwhile, will insist they’re messages from beyond. Yet the hard-headed answer isn’t much more plausible than the kooky one. If dreams are random brain-firings, how come they have coherent narratives? And if they’re just a dull retread of everyday events, how come they’re so often wildly inventive, haunting or surreal? (Don’t worry, I won’t bore you with any of my own, though the famous fact that “nothing is more boring than other people’s dreams” is, in itself, rather interesting.) As James Hollis, a Jungian psychotherapist for whom dreams are far from meaningless, writes: “Who would make this stuff up?” Night after night, you go to bed and elaborately crazy stories plant themselves in your mind through no choice of your own! Don’t tell me something intriguing isn’t going on.Membership Event: Guardian Weekend Live Continue reading...

Neurosurgeon Sergio Canavero is in the news again, claiming to have performed the first successful human head transplant. But even cursory analysis reveals that he hasn’t. And scientific logic suggests he never willIn February 2015, Sergio Canavero appeared in this very publication claiming a live human head will be successfully transplanted onto a donor human body within two years. He’s popped up in the media a lot since then, but two years and nine months later, how are things looking?Well, he’s only gone and done it! As we can see in this Telegraph story from today, the world’s first human head transplant has been successfully carried out. Guess all those more timid neurobods who said it couldn’t be done (myself included) are feeling pretty foolish right now, eh? Continue reading...

Shetland: famous for its irascible ponies, snuggly jumpers and now, perhaps, space exploration. UK Space Agency research has identified Unst, the Shetland Islands’ most northern isle as the best site in UK for spaceport to launch satellites into orbit. Which, teamed with the news that a potentially habitable world, Ross 128b, has been found just 11 light years away means exciting times could well be ahead. In the here and now, however, scientists have made their first ever attempt at gene editing inside the body. It’s a somewhat nerve-wracking experiment: Brian Madeux, who has Hunter syndrome, has been intravenously given copies of a corrective gene and a genetic tool to cut his DNA in a precise spot. It will permanently alter his DNA, with no way to alter any mistakes editing may cause. Also raising hopes for new treatments, this time of age-related disorders, is the discovery that some members of a small Amish community in Indiana, US, carry a rare genetic mutation which appears to protect against biological ageing. So new treatments plus dog ownership (which cuts your risk of dying from cardiovascular disease, apparently) could make us healthier than ever. Great, because in my fave news of the week, it seems we’ve been making and drinking wine for much longer than anyone thought, which probably needs balancing out. Continue reading...

I was 22 and fascinated by fish behaviour. But when scientist Amanda Vincent showed me this strange creature I became convinced that my future lay in conservation — not in the labLike many of the most important occasions in my life, the moment that changed me involved fish. Holding the desiccated carcass of a sea moth while talking to my heroine, the fish biologist and conservationist Dr Amanda Vincent, altered the course of my life.I was 22, and had just finished my biology degree. For my dissertation research I had spent a couple of months following butterflyfish in the Ras Mohammed national park in the Egyptian Red Sea. I had grown to recognise them by their individual markings and, by snorkelling at a discreet distance, I had mapped their territories and recorded their daily routine. Continue reading...

Health benefits of a pet dog are greatest for those who live alone, lowering the risk of dying from cardiovascular disease by 36%, say scientistsNever mind the chewed slippers, the hair on the sofa, and the inexplicable barking at 3am. Having a dog in the home substantially reduces the risk of heart attacks and other fatal conditions, a major study has shown.Researchers found that dog ownership had a dramatic effect on people who live alone, cutting the risk of death from cardiovascular disease by 36%. In households with more people under the same roof, dogs had less of a positive impact, but still lowered deaths from heart disease by 15%, the work reveals.

My friend Frederick Kurzer, who has died aged 95, was reader in chemistry at the Royal Free hospital school of medicine and a fellow of the Royal Society of Chemistry for more than 70 years.The son of Jacques Kurzer, a dealer in oriental rugs, and his wife, Rosa (nee Löwy), Frederick was born in the spa town of Carlsbad (now Karlovy Vary) in the German-speaking area of what was then Czechoslovakia. With one sister, Dorothy, he lived in Carlsbad and went to the local school until 1939, when the family fled to London to escape the Nazis. He attended Clark’s college, Cricklewood, and from there went to Regent Street Polytechnic (now part of the University of Westminster), where he studied for a chemistry degree. In 1940, like many German-speaking Jewish men, he was interned by the British government on the Isle of Man. Continue reading...

There are good reasons to be cautious about a new study claiming computer-based training can reduce the risk of dementia. But what does work?More than 30 million people worldwide live with Alzheimer’s disease, and while researchers are pushing hard to find a cure, their efforts so far have met with failure. With no effective treatment on the horizon, prevention has become the only game in town. But what can be done to reduce the risk of dementia, now the leading cause of death in England and Wales?In research published on Thursday, US scientists claim that a form of computer-based brain training can reduce the risk of dementia by 29%. The training was designed to speed up people’s visual information processing, for example by having them spot a car on a screen, and a truck on the periphery of their vision, at the same time. Those who are claimed to have benefited trained for an hour, twice a week, for five weeks, and some went on to have booster sessions at the end of the first and third years. To see if the training made any difference, the participants sat tests up to 10 years later.

In our new normal, experts are dismissed and alternative facts flagrantly offered. This suspicion of specialists is part of a bigger problemWe often defer to others’ expertise, and for good reason. The entire edifice of modern society only exists thanks to the division of labour, from construction to machine operation to medical treatment. The system works as long as we have trust in others’ knowledge, skills and intentions.This trust is often tested, most notably of late in relation to those who specialise in politics. People-powered movements from anarchism to populism want to see equality of participation in political decision-making. Indeed, this is at the heart of all versions of democracy. It raises the question of whether we should trust political insiders. Continue reading...

A look at the barrage of recent articles about how millennials can buy a home on a modest income reveals how unhealthy these pieces – and the expectations around them – really areLife in the modern world is hard. Even without all the Nazis and climate change, there are still countless things to pile on the stress. Obviously, those of us in the first world have it much better than those elsewhere; our lives aren’t one long gruelling struggle for survival, we have things very easy on that front. But that’s not quite how the brain works. Our normal lives, no matter how objectively privileged they may be from an outside perspective, provide the “baseline” for our expectations, and stress is experienced by things that challenge or disrupt that. As a result, while we may never have to worry about where the next glass of clean water is coming from, we still have a plethora of psychological stressors to choose from, many of which stem from the demands and expectations of the society around us.One modern societal pressure, in the UK at least, is that of owning property. It’s supposedly the done thing, buying a house or whatever, and often with a view to making a profit on it later, so much so that, in London particularly, people’s homes can earn more than they do. However, in recent years this expectation has been hit by countless obstacles, many of which have culminated in younger people simply not buying homes. This, obviously, threatens the status quo, which is something those with power and influence would rather avoid. Continue reading...

It’s difficult to imagine the voracious and predatory great white shark as prey. Could orcas really be overpowering them and removing their livers?The great white shark, Carcharodon carcharias, is considered the most voracious apex predator in temperate marine ecosystems worldwide, playing a key role in controlling ecosystem dynamics.As a result, it is difficult to imagine a great white as prey. And yet, earlier this year the carcasses of five great whites washed ashore along South Africa’s Western Cape province. Ranging in size from 2.7 metres (9ft) to 4.9 metres (16ft), the two females and three males all had one thing in common: holes puncturing the muscle wall between the pectoral fins. Strangest of all, their livers were missing. Continue reading...

Ten years ago, there was excitement about the prospects for science and innovation across the Islamic world. Was this optimism misplaced?Last week, almost 3,000 scientists and policymakers from 120 countries gathered on the shores of the Dead Sea in Jordan for the 2017 World Science Forum. It was a landmark moment for Jordanian science, and a tribute to the vision of Princess Sumaya bint El Hassan, president of Jordan’s Royal Scientific Society, who is in the vanguard of a new generation of leaders championing science and innovation in the region. Jordan is also home to the Middle East’s first advanced light source facility – the Synchrotron-Light for Experimental Science and Applications, or Sesame – which was inaugurated earlier this year as a shared resource for researchers from Cyprus, Egypt, Iran, Israel, Jordan, Pakistan, the Palestinian Authority and Turkey.In its final declaration, the World Science Forum called for more scientific cooperation to promote peace and address regional challenges. But the meeting also provided an opportunity to take stock of the state of science across the Middle East and wider Islamic world. And while the symbolism of the Sesame project was rightly celebrated, there was little of the outright optimism that characterised these debates ten or fifteen years ago. Continue reading...

Forgotten home of Bradford Park Avenue, abandoned when club folded in 1974, hailed as ‘Angkor Wat of football’In his 40-year career as an archaeologist, Jason Wood has travelled the world, searching for Roman remains in Jordanian citadels and helping to restore royal palaces in Nepal. But his recent project was a little less exotic: digging up a patch of grass by some woods in Bradford.Ever since he was a small boy, Wood had been thinking about the site on Horton Park Avenue, across the road from the ornate Grand Mosque. He remembered his dad pointing out the overgrown grass where a football club had once stood, wondering for decades how a ground that could hold 37,000 fans could be left to the worms and the weeds.

Fossils from China show that evolution found an alternative – and ultimately overly-complicated – way to increase the size of the earliest tree trunksIn the world of knee-high land plants 400m years ago, the battle to grow tall was won by plants which found biomechanical solutions to fight gravity. Vascular plants had already evolved a plumbing system, allowing them to transport water, and the food produced by photosynthesis, around the plant. The water-conducting cells in the xylem – dead, hollow and stiffened by the polymer lignin – also afforded them some structural support. But there are limits to the height that a plant can grow with a stem of fixed girth. Continue reading...

Traditional farming strategies could protect humanity against global warming and prevent deadly wildfires. Yet scientists seem determined to ignore themPrejudice against indigenous people is visible and ingrained in cultures everywhere, from US football team names (the Washington Redskins for example) to Hindu folk tales where the forest peoples are rakshasas, or demons.But it’s arguable that these prejudices also influence our science and policy. Take, for example, the specialised method of rotational farming used by many indigenous farmers all over the world but particularly in the global south. Farmers use seasonal fires to clear and farm parcels of natural landscapes and rotate their crops while the previously farmed parcel is allowed to regain fertility and natural vegetation – a method known as swidden agriculture. This technique helps preserve the soil quality and creates variation that helps counter the dominance of a few species and promotes biodiversity. It also helps prevent larger wildfires of the type that ravaged California recently, leaving 41 people dead and causing financial losses worth $30bn (£22.7bn). After decades of neglect, the US Forest Service is now embracing the Native American methods of fire management. Continue reading...

BBC Radio 4 listeners (and John Humphrys) are fuming over an ‘unwelcome linguistic epidemic’. In fact, it goes back as far as BeowulfAnother day, another linguistic bugbear held up for ridicule. This time, it’s the harmless, modest, blink-and-you-miss-it word “so”. What has this innocent syllable done to offend the British public? If you have been struggling to get through to the BBC recently it’s because their switchboard has been jammed with complaints about it.Here’s Robert from Wakefield: “I have been increasingly irritated over the last couple of years by the increasing use of the word ‘so’ when prefacing a sentence.” (I know how you feel Robert, I’ve been increasingly irritated by the increasing use of the word increasing). And Kay from Belfast: “I don’t think ‘so’ is an appropriate word with which to begin a sentence.” Continue reading...

Every day millions of internet users ask Google life’s most difficult questions, big and small. Our writers answer some of the commonest queriesInevitably, yes. The question is, how deep is your love? Narcissism is seen by some as a matter of layering. For Freud, there is primary and secondary narcissism – primary narcissism meaning the drive for self-preservation, and secondary narcissism meaning seeing yourself as if from the outside and thinking, you are great. You’re pretty much born with the first one (although it can get eroded), and then the second one comes along later. If you’re a basically nice person, your well-balanced narcissism won’t get in the way of your capacity to love other people.Related: This narcissism epidemic is harming women far more than it harms men | Madeleine Bunting Continue reading...

New genetics research settles questions about the peoples of Newfoundland and Labrador – and helps highlight what genetics can’t tell usGenetics research has transformed our understanding of human history, particularly in the Americas. The focus of the majority of high profile ancient DNA papers in recent years has been on addressing early events in the initial peopling of the Americas. This research has provided details of this early history that we couldn’t access though the archeological record.Collectively, genetics studies have shown us that the indigenous inhabitants of the Americas are descended from a group that diverged from its Siberian ancestors beginning sometime around 23,000 years before present and remained isolated in Beringia (the region of land that once connected Siberia and North America) for an extended period of time. When the glaciers covering North America melted enough to make the Pacific coast navigable, southward travel became possible, and patterned genetic diversity across North and South America reflects these early movements.

Unst, which has a population of only 600, is identified in UK Space Agency research as best site in UK for spaceport to launch satellites into orbitFor the 600 residents of the most northern island in the Shetlands, it could be the most exciting thing since Unstfest – the annual shindig that this year offered, among its attractions, a scything demonstration over-16s could join.The proposals are at an early stage, but if the Shetland Space Centre Ltd gets its way, Unst could become the UK’s premier spaceport with a local economy revitalised by blasting satellites into orbit. The company was set up on the island, a breathtaking fragment nearer Norway than Edinburgh, after it was identified as the most promising launch site in Britain, in a study supported by the UK Space Agency.

A new study claims a link between screen time and increased rates of depression and suicide in US teens. But what do the data actually say? And how can we move towards a more rational debate about digital technology?Screen time is one of the more divisive contemporary issues in psychological science. In a sense, this is no surprise – smartphone use, particularly among children and adolescents, has consistently increased in recent years. And as with any new form of disruptive technology, there are questions around what constitutes healthy and maladaptive use, both at an individual and societal level.The problem with the debate about screen time, however, is that very often the arguments devolve into overly-simplistic scaremongering claims. This peaked back in August, with the publication of an opinion piece in the Atlantic by Jean Twenge, professor of psychology at San Diego State University. Under the headline Have Smartphones Destroyed a Generation?, Twenge argued that teenagers are on the verge of a catastrophic mental health crisis, and the culprit was the smartphone.

As more drug companies prevent sales of their products for execution, some US states have seized on new, untried drug combinations – raising big ethical issuesToday, Scott Raymond Dozier was scheduled to be executed by lethal injection in Nevada’s Ely State Prison. However, the execution has been postponed over concerns around the untested drug combination proposed as the method of death. The postponement is the latest incident in a series of controversial state executions carried out in the United States this year, and brings to the foreground many concerns and ethical issues around state execution – not least the use of the death penalty itself.In Dozier’s case, a completely new three drug combination has been proposed for Dozier’s execution. The mixture of diazepam (a sedative), cisatracurium (a muscle relaxant), and fentanyl (a powerful pain-relieving opioid) has raised many concerns – principally because it is completely untried. Continue reading...
