Psychologists offer their best tips for staying on track in 2018, from taking on your challenge in the morning to cutting yourself some slack• Don’t think of it as a New Year resolution, says Charles Duhigg, the author of The Power of Habit – think of it as a new year plan. “Much more important than setting a far off goal, like running a marathon, is to set an immediate plan that you can start right away.” Start with baby steps – running half a mile every Monday morning, for example – and you can work upwards.

A clinical psychologist suggests a three-pronged plan for tackling anxiety and approaching each day logically and positivelyLet us start by considering why some people catastrophise – that is, on hearing uncertain news, they imagine the worst possible outcome. After all, it is not uncommon and those who catastrophise seem to do it a lot. Catastrophisers tend to be fairly anxious people. Whether this characteristic is principally genetic or more the result of learning is unknown. High levels of anxiety are extremely unpleasant, so we look for ways to discharge those unpleasant feelings as quickly as possible. If a catastrophiser is told something inconclusive – for example, if they go to a GP and are asked to have tests – they look for a way to feel in control again immediately. They learn to choose the worst possible outcome because it allows for the greatest sense of relief when they are reassured.Considering all possibilities is not a bad strategy if you examine them logically. However, unable to bear their distress, catastrophisers rush to external sources to calm themselves down: checking whether anyone else has “come through” the same problem; matching symptoms online to obtain a diagnosis and treatment options; asking a professional to tell them that they will survive. Once they are reassured, they feel better – in psychological jargon, they have “rewarded” this seeking behaviour. The next time they feel uncertain or threatened, they will ratchet up their anxiety with a catastrophic thought, then look outwards for reassurance even faster than before. In this way, catastrophising soon becomes a well-entrenched habit. The greatest problem with seeking others to alleviate anxiety is that it offers only temporary relief. There is always another source to check or another opinion to be had; as a result, catastrophisers feel anxious again increasingly quickly. The only way to break this cycle is to tame anxiety. After this, you can still seek advice. So, if you are a catastrophiser and you would rather not be, how do you go about making changes? Continue reading...

Officials declare state of emergency after 86cm of snow falls in north-eastern US, as typhoons hit nations closer to equatorThe magic of a picture-perfect white Christmas is something many long for year after year. Erie, Pennsylvania was the place to be this year, where a whopping 86cm (34in) of snow fell on Christmas Day.This 24-hour snowfall shattered the previous Christmas record (20cm) and even broke the all-time snowiest day in the city’s history (51cm) on 22 November 1956.

This was the year that analysis of data finally backed up a prediction, made in the mid 1970s, of a surprising emergent behaviour in the strong nuclear forceIn the mid 1970s, four Soviet physicists, Batlisky, Fadin, Kuraev and Lipatov, made some predictions involving the strong nuclear force which would lead to their initials entering the lore. “BFKL” became a shorthand for a difficult-to-understand but important physical effect which could have big implications for high energy physics.The strongest of the known fundamental forces of nature is something of an enigma. It holds together the nucleus of every atom – easily overcoming the electromagnetic repulsion between the positively-charged protons in there. The simplest atomic nucleus, that of hydrogen, is a single proton, but even that is held in one piece by the strong force, so tightly that it never falls apart – or at least, it lives billions of times longer than the current age of the observable universe. Truly, strong and stable. Continue reading...

We’re highlighting interesting conversations on the site – including another year without a pay rise, and space exploration

Our team of experts round up a few of the best fossil discoveries of 2017

The value of calm reasoning – the cornerstone of democracy – is acknowledged rarely today. Even when we think we’re being rational, we don’t know what that isIt’s been coming on for a while, so I can’t claim any eureka moment. But something did crystallise this year. What I changed my mind about was people. More specifically, I realised that people cannot be relied upon to make rational choices. We would have fixed global warming by now if we were rational. Instead, there’s a stubborn refusal to let go of the idea that environmental degradation is a “debate” in which there are “two sides”.Debating is a great way of exploring an issue when there is real room for doubt and nuance. But when a conclusion can be reached simply by assembling a mountain of known facts, debating is just a means of pitting the rational against the irrational. Continue reading...

Deputy prime minister admits programmers gave the $45m device coordinates for Baikonur rather than Vostochny cosmodromeRussian deputy prime minister Dmitry Rogozin said on Wednesday the loss of a 2.6bn-rouble ($45m) satellite launched last month was due to an embarrassing programming error.Russian space agency Roscosmos said last month it had lost contact with the newly launched weather satellite – the Meteor-M – after it blasted off from Russia’s new Vostochny cosmodrome in the country’s far east.

As a child I felt constantly at risk, scared to walk the neighbourhood. Who knew if a free-ranging dog might emerge from a driveway and rip my head off?Fears are not rational. But growing up, in my mind, it made perfect sense that a dog could bite me, and moreover, most likely would if given the chance.My fear was born of repeated backyard encounters with a mauling, snarling dog. We shared the yard with tenants who lived in the other part of our grandfather’s house. This meant our sandpit was contested territory, my dolls were easy targets, and my young mind was easily imprinted with the image of slavering jaws crushing heads. Dolls’ heads, true, but that had implications. Continue reading...

Offering e-STI kits alongside existing sexual health services could improve testing rates, research indicatesOffering young people testing kits for sexually transmitted infections (STIs) over the internet almost doubles testing uptake compared with inviting them to a clinic, research suggests.In 2016 alone there were more than 417,000 diagnoses of sexually transmitted infections in England, including gonorrhoea and chlamydia, with rates of STI diagnoses generally higher among young people. While the use of condoms can help to prevent the spread of STIs, a recent survey found that nearly half of under-25s questioned did not use one when having sex with a new partner.

Archaeologists clearing attics to create new museum space find 30,000 stained glass shards, some dating back to 13th centuryWhen the archaeologist Warwick Rodwell scooped up a handful of dust from the attics of Westminster Abbey and saw dozens of tiny fragments of glass glittering in the grime, he realised they were dealing with excavation, not house clearance.The salvaged glass – some dating back to the 13th century, including stars, flowers and sun rays, fierce little mythical animals and beautiful medieval faces – is being recycled into dazzling new windows being made for the abbey at the stained glass studio at Canterbury Cathedral, where some of the original medieval glass artists may have worked.

Two hundred years after the publication of Frankenstein, how relevant are the themes and concerns of Shelley’s gothic tale to today’s readers?Subscribe & Review on Apple Podcasts, Soundcloud, Audioboom, Mixcloud & Acast, and join the discussion on Facebook and TwitterOn 1 January 1818, a small publishing house in London produced 500 copies of a novel that would go on to define a genre and resonate for centuries to come: Mary Shelley’s Frankenstein; or, The Modern Prometheus. Its reputation is now cemented as a classic gothic tale, but underneath the horror lie complex themes and explorations of ownership, what constitutes the essence of life and, of course, concerns around the progress of science. But how was it that Shelley came to write this masterpiece? Are we any closer to identifying the “spark” of life? And from a scientific point of view, what can this 200-year-old story tell us about our attitudes toward the “natural” and “unnatural” worlds? Continue reading...

Harvard Business School finds that people are four times more likely to quit a line if there is no-one else waiting behind themNo-one relishes the moment. You are stuck at the back of a queue and as those in other lines sail past and get served, the time to decide arrives. Do you hold your nerve and stay put, switch to another line in the hope it moves faster, or give up altogether?The pressing question has now been tackled by research at Harvard Business School. It found that when a person finds themselves at the end of a queue, they can make decisions that swiftly backfire. And it is all down to our aversion to being last.

President’s ambitious proposals leave many questions unanswered, and experts’ cautious optimism is tempered by reservations about the detailsThe world is not enough for Donald Trump: he has declared space “the next great American frontier” and mused to Congress that “American footprints on distant worlds are not too big a dream”.Earlier this month, the president ordered the agency to head back to the moon. “This time we will not only plant our flag and leave our footprint, we will establish a foundation for an eventual mission to Mars, and perhaps someday to many other worlds beyond,” he said, before signing the new policy for Nasa.

Linguist who went on from his survey of English as used in Britain to promote Standard English, the written form common to speakers from all round the worldIn 1959 Randolph Quirk, who has died aged 97, embarked on a long-term project to produce a comprehensive analysis of British English as it is actually used in the present day, rather than as reflected in the distorting mirrors of ivory-tower linguists and armchair pedants. In doing so he came to have an enormous influence on the development of English language studies worldwide, particularly through his advocacy of Standard English, the common written ground maintained despite variations in speech, as a way of opening doors educationally.On his appointment the following year as professor at University College London, he read a paper to the Philological Society laying out the ground plan for a large-scale Survey of English Usage. Its goals were to compile and investigate a corpus or databank of spoken and written English. In Quirk’s view, deeply unfashionable at that time, good, reliable accounts of the language must rest securely on a wide sampling of authentic, observed language in use. To rely on the intuition of a native speaker was not enough. Continue reading...

My friend Zbigniew Kotowicz, who has died of cancer aged 67, was a rare, proud, sometimes solitary man with a gift for friendship. He wrote four acclaimed books: on the Portuguese writer Fernando Pessoa, on the neurologist Egas Moniz (originator of psycho-surgery), on the psychiatrist RD Laing and on the philosopher Gaston Bachelard. The books themselves are impressive, but their range more striking still. In an age of specialisation, Zbigniew was something of a polymath.A love of literature took root early, as did a radical’s commitment to the political left, broadly construed. Psychology and psychoanalysis followed. Then philosophy offered him a way to exercise his restless intelligence more freely. Its greatest gift was an introduction to the work of Bachelard, who became the point around which all his thinking turned. Continue reading...

Former Nasa biochemist Josiah Zayner became an online sensation by conducting DIY gene therapy on himself. He explains why he did itJosiah Zayner, 36, recently made headlines by becoming the first person to use the revolutionary gene-editing tool Crispr to try to change their own genes. Part way through a talk on genetic engineering, Zayner pulled out a syringe apparently containing DNA and other chemicals designed to trigger a genetic change in his cells associated with dramatically increased muscle mass. He injected the DIY gene therapy into his left arm, live-streaming the procedure on the internet.The former Nasa biochemist, based in California, has become a leading figure in the growing “biohacker” movement, which involves loose collectives of scientists, engineers, artists, designers, and activists experimenting with biotechnology outside of conventional institutions and laboratories.

An atheist’s Christmas celebrates hospitality and generosity – just like a Christian’sAlthough I’m a card-carrying atheist, I have some sympathy with those who argue that a Christmas without Christ or a mass is as meaningless as celebrating a birthday without a birth, or a jubilee without a coronation.

This Christmas visit an older relative. For me Auntie Gillian’s bravery and sharp mind mean time spent with her is always a joy, never a choreMy Auntie Gillian is the bravest person I know. Now 85 and in declining health, she spends much of her time shuffling between two rooms holding on to her walking frame. Bent double with osteoporosis, she has not been out of her tiny house for three years. A widow for more than a decade since my uncle died, she has no children and is now completely reliant on carers to change her clothes and put her on the toilet. Over Christmas, they are the only people she will see, apart from me.My aunt lives over an hour away, which makes “popping over” difficult. Like so many people, I have countless calls on my time. So I have to make a really special effort to visit her and too often I find excuses not to bother. But when I do finally make the trip I’m always surprised how much I get out of our encounter. When I arrive my head is crammed with all the things I need to do at home or at work, yet by the time I leave many of these things will have been forgotten. Continue reading...

A wunderkammer of amazing facts inspires a better appreciation of the world and celebrates the wonder and explanatory power of scienceThe fate of our times,” wrote the sociologist Max Weber in 1917, “is characterised by rationalisation and intellectualisation and, above all, by the disenchantment of the world.” Though its urgency was new, Weber’s anxiety – that the rise of monotheism, followed by the gradual secularisation of culture and the march of science, were robbing the world of wonder – was an old one. In “Lamia”, published in 1820, John Keats expressed a fear that Newtonian optics would “unweave” the rainbow. In 1949, the critic Lionel Trilling warned of the “reductive spectre” of psychoanalysis which, he thought, “haunts our culture”. Nowadays, Trilling’s spectre has been replaced by what the writer and retired medical physician Raymond Tallis has identified as contemporary culture’s propensity toward “neuromania”: the belief that neuroscientific explanations for consciousness can fully account for all human experience and endeavour.Henderson wants to re-enchant the world, but not at the expense of scientific explanations of it Continue reading...

It’s a significant step: gene editing has been used to prevent a form of genetic hearing loss in mice, raising the prospect of a new class of therapies that could transform future treatment. That’s small comfort for dolphins though, as apparently there’s a species of Mexican fish that has orgies so loud they can deafen other sea animals. Inconsiderate, no? Luckily they’re nowhere near any of the instruments we have scanning the skies for signs of alien life, as they might drown out any bleeps, blips or bloops, but why do we keep looking for life on other planets anyway? And will we ever answer the question “are we alone”? One thing is certain, however: we find space objects fascinating – even when they’re covered in a “thick crust of carbon-rich gunk”, as interstellar visitor ‘Oumuamua was revealed to be this week. Maybe we just need to wait for other life forms to evolve a bit more before they make contact – after all, it’s not as though humans are standing still on that score. A new study suggests that evolution is still acting on contemporary humans, although over many generations and very weakly. Let’s hope alien evolution happens a bit faster than ours, eh? And finally, a seasonal plea: keep those selection trays and chocolate tree decorations well out of reach of your furry friends. A study has shown that cases of chocolate poisoning in dogs peaks at Christmas time, and although it’s seldom fatal, even modest amounts of chocolate can cause vomiting, agitation and seizures.

The search for alien life continues, but how near are we to finding life on other planets – and will we ever answer the question ‘are we alone’?In less than an hour, the decision was made. It was 2 December and Avi Loeb, an astronomy professor at Harvard, was with Yuri Milner, the Russian billionaire and founder of Breakthrough Listen, a $100m alien-hunting venture. Milner had invited Loeb, an adviser on the project, to his Palo Alto home to discuss the bizarre features of the interstellar object, ‘Oumuamua.The first known visitor from another solar system, the monolithic lump appeared long and slender, a curious shape for a space rock. The two agreed there was the slimmest chance ‘Oumuamua was not what it seemed. Eleven days later, Breakthrough Listen swung the world’s largest steerable telescope, at Green Bank in West Virginia, into position and scanned the 400-metre-long body for signs that it was a passing spacecraft.

The Gift, written by Marcel Mauss in 1925, explores why we exchange things and the social rules we follow – and might help explain why gift-giving can be so fraught with worryExchanging stuff – as gifts or economic transactions – and reciprocating those exchanges in a socially acceptable way - is a practice found in all human cultures. The rules and scope of the exchanges may be very different, but the fact of them is universal.French anthropologist Marcel Mauss doesn’t attempt to explain the politics and practice of the office Secret Santa (alas) – instead, he describes “archaic societies” in Melanesia, Polynesia and the north-west coast Native American peoples who practiced ‘potlatch’, a ceremonial gift-giving and feasting ritual characterised by competitive shows of conspicuous giving and consumption. These, Mauss says, are systems of gift-giving that aren’t just about gifts, but carry legal, economic, spiritual and moral significance that saturates the whole social fabric (he calls them “total prestations”). In these societies, items given as gifts take on the spiritual significance of the giver. The value of the relationship is embodied in the thing given. Continue reading...

With hundreds waiting for heart transplants, experts and patients urge public to register as organ donors – and make their wishes clear to family membersFamilies are being urged to talk about becoming an organ donor in the hope that more people on the waiting list for a heart transplant will be given the chance of life.Since last Christmas Day, 31 people have died on the heart transplant waiting list, according to NHS Blood and Transplant. To try to tackle the shortage of organs, the government has recently announced a consultation into an “opt-out” scheme. Everybody would be assumed to be willing to donate their organs unless they had signed up to a register to say no. Continue reading...

Nasa has selected two concepts for further study – for a robotic mission to launch in the 2020s, the fourth in its New Frontiers programmeA sample return spacecraft to a comet and a drone to fly across a moon of Saturn are the two robotic mission concepts chosen for further study by Nasa this week. Both proposals build upon previous missions performed by the European Space Agency.The Comet Astrobiology Exploration Sample Return (Caesar) mission would revisit comet 67P/Churyumov-Gerasimenko. This is the icy body that ESA explored with its Rosetta spacecraft and Philae lander in 2014. Continue reading...

My father, Bryan Aves, who has died aged 92, established a successful career as a radiographer and radiotherapist despite having left school at 14 without qualifications. At one point he worked as an assistant for the physicists Otto Frisch and Joseph Rotblat in the secret “tube alloys” experiments that led to the creation of the atom bomb, apparently without knowing what the project was about.Born in Brixton, south London, to Arthur, an accounts clerk for a dog biscuit factory, and Ellen (nee Stallard), a cleaner, Bryan had a cleft palate at birth; reconstructive surgery was not undertaken until he was 13. Because of the Depression his father struggled for work and the family moved frequently – Bryan attended more than 10 schools, and his education was basic. Continue reading...

Ever since Rudolph first starred in a 1939 story, we’ve been getting him all wrong. Or should I say her? Let’s look at the science behind the world’s favourite reindeerIt is coming up to Santa’s busy time. Last minute preparations are being made, lists are being checked and double checked, routes are being analysed and optimised. Elves will be working overtime to put the finishing touches to their orders. But please spare a thought for Rudolph and the team of reindeer called on to drag tons of presents over thousands of miles in the most appalling weather.

Mini-ponds have formed in the surface roots of an ancient tree and provide an environment for minute organisms to thriveThe beech that stands at the end of the stepping stones across Waskerley beck is an elephantine presence, dwarfing surrounding trees. The scarred grey bark of its bole has the colour and texture of pachyderm skin. Its moss-covered surface roots seem to be melting into the earth under the massive burden they support. Over decades they have grown and coalesced, creating hollows between them that retain water, fed by rivulets of rainwater trickling down the trunk.There is a name for these mini-ponds that form on the surface of plants and are habitats for small aquatic organisms: phytotelmata, which translates from the Greek root as “plant ponds”. The best studied are those contained by leaf bases of urn plants or bromeliads that live on branches in rainforest tree canopies. They are breeding sites for frogs, dragonflies and even land crabs.

Chocolate poisoning peaks during the festive period, say researchers, with even modest quantities able to cause vomiting, agitation, seizures and even deathDog owners need to be vigilant in keeping chocolate away from hopeful muzzles over Christmas, vets have warned, with research suggesting that the risk of canine poisoning from the confectionery peaks during the festive period.Chocolate can be toxic to dogs since canines break down a substance known as theobromine more slowly than humans, meaning that even seemingly modest quantities can result in vomiting, agitation, seizures and – albeit rarely – death.

It’s meant to be a time of good cheer, relaxation and celebration, but for many, Christmas is stressful. The reasons are more varied than you might thinkIt’s Christmas! Time off work. Gifts to give and receive. Eating and drinking as much as you like. Seeing friends, family, loved ones. The atmosphere of goodwill and cheer. What’s not to like?Quite a lot, actually. Christmas is often a source of great stress for many. At least one study suggests that it can literally give you a heart attack. Obviously, many people have good reason to not like Christmas, be it estrangement or loss of their own family or friends, trauma experienced during the festive period (with all the context cues constantly bringing the unpleasant memories flooding back) and so on. But, if you look at the modern manifestation of Christmas, it turns out there are a surprising number of elements that can, and probably do, lead to an increase in stress, rather than the opposite.

With do-it-yourself Crispr kits now available online, Hannah Devlin asks if it’s really possible to edit your own DNA, is it safe and how should it be regulated?Subscribe & Review on iTunes, Soundcloud, Audioboom, Mixcloud & Acast, and join the discussion on Facebook and TwitterIn October, biohacker Josiah Zayner gave a lecture in San Francisco in which he claimed to be the first person known to have edited his own DNA using Crispr technology. He insists it’s something anyone can do using one of his company’s gene engineering kits. But does this do-it-yourself approach have any evidence to back it up? Is it safe? And, ultimately, does this kind of self-experimentation drive science forward or expose the public to unacceptable risks? Continue reading...

From BF Skinner’s behaviourism to Milan Kundera’s existential comedy, these are some boldly counterintuitive guides to the part of ourselves we know leastTo what extent are our conscious intentions and strategies in control of our choices and decisions, our feelings and actions? The 20th century provided three different answers to this basic existential question: Freud’s psychodynamic theory placed a hidden and self-destructive unconscious mind in charge; Skinner and the behaviourists put control instead with the outside stimulus environment. Finally, cognitive science threw out the behaviourists and reinstated the conscious mind at the helm.When I started out in the 70s, these three camps were arguing but with hardly any actual evidence, so I began to study these issues scientifically. Before You Know It is the culmination of more than three decades of such research, from labs around the world, on the variety of unconscious influences in everyday life. These 10 books were my signposts along the way.

Diprotodon was the largest marsupial ever to live. New evidence shows it migrated annually – and could make us reassess what we know of other extinct marsupialsPerhaps nowhere is the debate regarding the causes of megafaunal extinction more prominent than in Australia. During the Pliocene and Pleistocene epochs, a magnificent suite of giant marsupials (mammals who carry their young in a pouch), reptiles and birds roamed Australia, only to meet their demise at the end of the Pleistocene. Why these behemoths disappeared has been, and continues to be, the subject of extensive discussions.Much of the debate revolves around the timings of megafaunal extinctions, the arrival and spread of modern humans in Australia, and the role of climate change. However, as reliable dates for many of the extinct species are lacking and the arrival of modern humans in Australia keeps getting pushed back in time, the debate remains far from being resolved. Therefore, some scientists argue that if we want to know what really happened, we need to step away from the dating game, and start looking more into biological and ecological variables that contributed to the megafaunal demise.

Crest-tailed mulgara caught in a trap by University of NSW researchers working on Wild Deserts projectA tiny carnivorous marsupial that was presumed extinct in New South Wales has been discovered just inside the border, two years before scientists planned to reintroduce it.The juvenile female crest-tailed mulgara, Dasycercus cristicauda, was caught in a trap in November by University of New South Wales researchers working on the Wild Deserts project, which aims to reintroduce long-absent marsupials to two predator-free areas of the western edge of Sturt national park.

Mating call of the Gulf corvina, which is under threat from overfishing, sounds like ‘a really loud machine gun’A species of Mexican fish amasses in reproductive orgies so loud they can deafen other sea animals, awed scientists have said, calling for preservation of the “spectacle” threatened by overfishing.
