The US right is misrepresenting science to support its racist agenda. There's far more to it than good' or bad' genesLike so many of us, I was dispirited to wake up a few weeks ago to learn that Donald Trump will be back in the White House. This time he was aided by the world's richest man and professional spaceship-crasher, Elon Musk. Among the many charming aspects of their partnership is a fondness for some highly unsavoury views on genetics. Trump is an enthusiastic advocate of racehorse theory", which he shares with white supremacists; the belief that he is personally superior and that this is rooted in his good genes". It's a vapid idea, but it directly informs his toxic views on immigration, where he argues the country needs to be shielded from the bad genes" of outsiders.Meanwhile, Musk has his own equally baffling take on genetics, infused with a characteristic messiah complex. Like some of his fellow tech moguls, he is determined to save humanity" by producing as many offspring as possible, convinced that our future depends on it. This might all be laughable were it not for the fact that Trump and Musk now wield more power than they ever have before. The shared thread running through their rhetoric is genetic determinism: the idea that who you are, and what you can achieve, is all down to your DNA. Nothing else matters.Jonathan Roberts is a genetic counsellor and academic who researches health inequalities and the accessibility of genetic testingDo you have an opinion on the issues raised in this article?

Our brains are miraculous and weird things, and it turns out everyone has different ways of processing the worldSometimes I like to start a column by asking myself: should this really be a column that will live on the internet forever, for all and sundry to see? Or is this really an airing of my many neuroses that is better shared privately, with a therapist?Not infrequently the answer is the latter. But therapy is expensive and comment is free, so I'm afraid, dear reader, that you're going to have to be my shrink today. And I'll get straight into my issues: I have a voice in my head that won't shut up.Arwa Mahdawi is a Guardian columnist Continue reading...

Jupiter, the largest planet in our solar system, will be the brightest object in the constellationFinish the year by tracking down one of the oldest known constellations: Taurus, the bull. The chart shows the view looking south from London at 22.00 GMT on 30 December. The view will remain essentially the same all week.According to Babylonian star charts from about 1000BC, the grouping of stars we now call Taurus was known as the bull of heaven. However, the pattern's association with a bull could be much older: some believe that the constellation can be found embedded in the 17,000-year-old cave paintings of bulls at Lascaux in France.

Social monogamy has been observed in less than 10% of mammal species - and birds have been shown to be less faithful than previously believed

My husband, Colin Robson, who has died aged 89, pioneered the degree of behavioural sciences, combining psychology and sociology, in the 1970s. The fifth edition of his textbook Real World Research, originally published in 1993, came out earlier this year.Born in the village of Almondbury, near Huddersfield, West Yorkshire, the only child of Mary (nee Addy) and Raymond Robson, a clerk in the council rates office, he attended King James's grammar school in the village, remaining loyal to his home town and its football team all his life. After studying physics at Manchester University, he signed up for a PGCE at King's College London, where he came across psychology for the first time. Continue reading...

Existing evidence is dominated by western regions but researchers want to find out whether benefits are the same around the worldThe science of happiness has spawned hundreds of thousands of studies, surveys, books and reviews, but what reliably lifts the spirits, to what extent, and who benefits most are still far from nailed down.Now, psychologists have drawn up plans for the world's largest happiness experiment to thrash out once and for all what really gives people an emotional boost, how effective different strategies are, and whether the benefits are the same around the globe.

I always thought genealogy was as dull as looking at other people's holiday snaps - until I found out about a 16th-century architect who transformed the stately homes of his eraFriends and family, back in the 1970s, would often aggravate each other with a lengthy holiday slideshow, presenting a string of identical beach views and nameless hillside vistas over the course of a dull evening. Today, there is a new phrase that can freeze the heart just as easily as the sight of a slide projector, and it is: I've done some research into my family history and you'll never guess what I've found out!" A scroll bearing a family tree unrolls to reveal a roster of Jacks and Noreens, leading back to some Charleses and Marys, each perching on ever-more-distant branches and ultimately signifying little about the people who are actually living and breathing around you.For me, this became a domestic issue a while ago, because my husband, a history buff, takes genealogy quite seriously. To be fair, he was early to spot the wider growing public interest in family history as a hobby, even before the genetic element had truly taken hold with the arrival of rival commercial DNA-tracing services.

Time flies when you're... in a boring routine, according to research, which shows that new experiences, from foreign travel to a walk in nature, can alter our perception of timeIt's the time of the year for endless cliches. From tis the season" and the gift that keeps on giving" to new year, new you", there's nowhere to hide from tired old phrases. One of my favourites is Christmas comes around quicker each year" - which ignores the fact that one year equals one trip around the sun.There's often a kernel of truth in a cliche, though. A recent study by Ruth Ogden from Liverpool John Moores University and colleagues showed that the vast majority of people in both the UK and Iraq really did experience Christmas (or Ramadan) approaching more rapidly every year. This may be down partly to festive decorations appearing ever earlier in the season. But it's also a result of how we perceive time psychologically. Continue reading...

In 2024 horticulturalists made single biggest introduction of rare seeds to collection in the past decadeThe Codonopsis clematidea smells like a skunk, the Tulipa toktogulica has a peculiar, elongated bulb and the Fritillaria imperialis is exceptionally tall. But to the horticulturalists who journeyed to remote alpine meadows and forests to find these rare flowers growing in the wild this year, they are nothing less than the jewels of the earth".Now, the seeds from these and hundreds of other wild plants that were collected in Georgia and Kyrgyzstan have entered the living collections at the Royal Botanic Gardens at Kew.

With the aid of the birds I was able to learn to love the nightAs a child I was afraid of the dark, as so many children are. Not the dark in and of itself, but what I was certain it contained: bad spirits, bad people, monsters with ill intent. The dark hid creatures with talons and teeth, or men with weapons who would use them to sneak up on an unsuspecting child and do them harm. The dark let curses slip out of buildings or hedges and attach to a child walking past. I kept myself bounded within the dome of torchlight on winter afternoons, thinking of light as a spell of protection. I went to bed by the orange glow of a nightlight, the hall light on and the door ajar.I borrowed Jill Tomlinson's book The Owl Who Was Afraid of the Dark from the library and fell in love with the baby barn owl, Plop. He thinks dark is nasty" and won't go hunting with his parents. He learns through others who love the dark that it can be exciting, kind, fun, necessary, wonderful, beautiful and super. I identified with Plop, but I wasn't convinced about the wonderfulness of the dark. Continue reading...

Academic Danilo Brozovi says studies of failed civilisations all point in one direction - today's society needs radical transformation to surviveFor someone who has examined 361 studies and 73 books on societal collapses, Danilo Brozovi's conclusion on what must happen to avoid today's world imploding is both disarmingly simple and a daunting challenge: We need dramatic social and technological changes."The collapse of past civilisations, from the mighty Mayan empire to Rapa Nui (Easter Island), has long fascinated people and for obvious reasons - how stable is our own society? Does ever-growing complexity in societies or human hubris inevitably lead to oblivion? In the face of the climate crisis, rampant destruction of the natural world, rising geopolitical tensions and more, the question is more urgent than ever. Continue reading...

Readers offer their views on getting rid of earworms using the composer's 4'33"In her letter (Want to get rid of a earworm? Try John Cage, 22 December), Joan Friend says shehas listened to different versions of 4'33'' and that they all sound the same". This is impossible, because the whole point of the piece is that during it we hear the sounds all around us.Composed after Cage had experienced an anechoic chamber, a room without echoes where true silence is possible, the score for the piece is marked Tacet" (an instruction in music which tells the player not to play), so here we have what appears to be a piece where nothing happens.

Why did we succeed when other hominins didn't, and can lessons from our evolutionary past help rein in our destructive impulses?In an institute in Germany, scientists are growing Neanderthalised" human brain cells in a dish. Thesecells form synapses and spark asthey would have done in a living Neanderthal as she (they are female cells) foraged or breastfed or gazed out of a cave mouth at dusk. That is the spine-tingling opening gambit of a book co-authored by one of the directors of the institute, Johannes Krause, and the information that sets it apart from a host of popular science books that attempt to predict humanity's future based on our evolutionary past.A mere 90 genetic differences distinguish modern humans, Homo sapiens, from Neanderthals, Homo neanderthalensis. That's paltry, given the roughly 20,000 genes that make upthe human blueprint, and not all ofthem affect the brain. Yet those 90differences could explain why Neanderthals died out, some 40,000 years ago, while we went on to dominate the planet. They could hold the key to how we, the apparently more adaptable human type, might adapt again before we destroy the ecosystems we depend on, and ourselves along with them. Continue reading...

Plant native to Sumatra boasts huge fly-attracting flower that can be sustained for only a few daysIt looks like a giant erect penis, stinks to high heaven and warms up to about the temperature of a human body. This is the inflorescence of the titan arum, Amorphophallus titanum, a plant with a phallus-shaped spike called a spadix that stands up to three metres tall, warms up to 36C at night and gives off the stench of a rotting corpse. This wonder is actually a ruse to attract carrion flies and beetles to pollinate the small flowers that are tucked away at the base of the spadix inside a large bucket-shaped leafy wrapper, where the insects are trapped until the flowers are successfully pollinated.A recent study revealed the plant's pungent odours were made up of a stinky cocktail of sulphur chemicals, including the aptly named compound putrescine, which is given off by rotting animal carcasses. This foul concoction is released only when the spadix warms up in short pulses. Continue reading...

Star-gazer's long-exposure shots unexpectedly capture mysterious blue light of triboluminescenceOn 27 October, photographer Shengyu Li set up his camera on a long exposure to record stars in the night sky near a mountain in Sichuan, China. As he waited, suddenly an unstable block of ice broke free from a glacier near the peak of the mountain and set off an avalanche. Looking at his photographs afterwards revealed mysterious blue flashes given off from the avalanche, when the ice crashing down smashed into rocks and the friction gave off the flashes of blue light. It was a phenomenon called triboluminescence, which occurs when certain materials are mechanically stressed from fracturing, scratching or rubbing.This strange effect was widely seen in the 1790s, when sugar began to be produced with more refined sugar crystals. These crystals were made into large cones which could be nipped into chunks as needed. If the nipping was done in dim light, it gave off tiny bursts of light. Something similar is caused by rubbing the sides of quartz crystals together or even when pulling sticky tape from a roll. Continue reading...

In this episode from July, Ian Sample talks to Josh Davis, a science writer at the Natural History Museum in London and author of the book A Little Gay Natural History.

After decades of debate, one of the largest ever studies on birth order suggests it does actually make a differenceThe debate has raged for more than a century: does birth order help to shape personality, or are conscientious firstborns and creative youngest children flawed stereotypes based on flimsy evidence?After decades of contested claims, a handful of recent studies found there was little evidence for meaningful differences. But in a study published on Monday, psychologists have pushed back and claim there is an effect after all. Continue reading...

Researchers in Russia have unveiled the near intact carcass of a juvenile female mammoth, whose remarkably well-preserved remains were discovered in thawing permafrost after more than 50,000 years. The creature was recovered from the Batagaika crater, a huge depression more than 80 metres (260 feet) deep which is widening as a result of climate change

Paul Collins on how to improve the criminal justice system, and Ellie Dwight on an understaffed and ineffective probation serviceIn the 1990s, judges attending Judicial Studies Board seminars would hear the late David Faulkner, a humane and immensely knowledgable Home Office star, explain how German prison sentences were so much shorter than ours, with no corresponding increase in offending. Politicians, terrified of being pilloried for being soft on crime, have never taken any notice. The problem is that wehave no principled national idea of what prison is for(Editorial,12 December).As a junior assistant recorder, I did my duty and gave long sentences to drug mules from South America, based on the ludicrous theory that the deterrent effect would resound with other potential drug mules, often semi-literate women coerced into criminal activity with no conception of the consequences. Retribution, deterrence, rehabilitation? Some shapeless idea of punishment for its own sake is the unquantifiable last refuge of the ideologically barren. But it's all we seem to have.

My colleague and friend, the psychotherapist, author and campaigner Paul Gordon, has died aged 70. While eschewing the limelight, Paul was an influential figure and unique voice in the world of psychotherapy. His political commitment and determination to improve people's lives led him to train as a psychotherapist at the Institute of Psychotherapy and Social Studies in London in the late 80s, and later at the Philadelphia Association, founded in 1965 by RD Laing and colleagues in order to challenge established ways of thinking about and responding to distress.Paul became its chair, and was a strong advocate for the unique sanctuary and asylum their therapeutic homes have long offered to anyone in need. Indeed, facilitating access to low-cost or free therapy was important to Paul, who also worked with young people at North London's Open Door, at Freedom from Torture, and helped to establish the Free Psychotherapy Network.

Readers respond to an article by Elle Hunt on the science of unshakeable tunesI have suffered from constant tinnitus for 30 years, and when it was joined by earworms it became almost unbearable (Tortured by an earworm? How to get it out of your head, 16December). I read of the cure" of listening to something else, but all that did was to replace it with something perhaps more irritating.Then I got to wondering: what would happen if I listened to silence? It wasn't music, so it didn't work. But then I began to listen to Cage's 4'33" - and amazingly, that did work, but not on audio only. Ihave to watch the music not being played. I have watched versions on the violin, guitar, full orchestra, string quartet, piano - it doesn't matter which it is because they all sound the same. Continue reading...

Data is used for the first time to show regional differences in the uptake of a single medicine - sodium valproate - and the potential benefits are striking say researchersScientists have created a unique map of England and Wales that reveals detailed variations in the use of a single medicine. The drug is sodium valproate, a treatment for severe cases of epilepsy that is also known to cause health problems for pregnant women.The findings show drops in the use of the drug, in response to warnings about its effects, but the map reveals clear differences in dispensing patterns to women of child-bearing age, with the highest rates being found in local authorities in the north-west and across coastal regions in the east. These variations highlight potential inequalities that need further investigation, the researchers warn. Continue reading...

After midlife burnout came a rediscovered curiosity for two friends and writersIt was the early 2000s, we were in our 20s and had both started as assistants at the same company. We bonded over excruciating induction sessions, where we had to reveal things like which cartoon character we most identified with (B: Danger Mouse; E: Marcie from Peanuts). We laughed a lot, but we also worked really hard - and pushed each other to do new things. Twenty years later, with six children between us as well as more senior jobs, we found ourselves bogged down by endless to-lists and the relentless pace of midlife. We realised we needed to rediscover and connect to the positives in the world around us. The answer lay in sparking each other's curiosity.Many studies have shown that having a curious mindset has real-life benefits, both for our bodies and our souls. Our brains have evolved to release dopamine when we discover new things, and dopamine boosts memory, creativity and forges new neural connections. Other research shows that having a driving sense of curiosity can break down barriers between people - particularly important in our increasingly polarised world - c uriosity helps us to build empathy, connectivity and respect for others.

Previously unseen artefacts show invading forces included communities of men, women, children, craftworkers and merchantsDozens of sites linked to the Viking great army as it ravaged Anglo-Saxon England more than 1,000 years ago have been discovered. Leading experts from York University have traced the archaeological footprint of the Scandinavian invaders, identifying previously unknown sites and routes.The study, conducted by Dawn M Hadley, professor of medieval archaeology, and fellow archaeology professor Julian D Richards, found that the significance of many of the ingots, gaming pieces and other artefacts unearthed by metal detectorists over the years had been overlooked until now. They also discovered about 50 new sites that they believe were visited by the Viking great army. Continue reading...
