Sir Denys Wilkinson obituary
Physicist and expert on the electromagnetic properties of nuclear isotopesIn 1943, the physicist Sir Denys Wilkinson, who has died aged 93, gained his first degree, and was immediately drawn into second world war service, initially on radar. From there he went on to nuclear physics, as a member of the British nuclear reactor team relocated from Cambridge to Canada until 1946 to facilitate collaboration with the US in developing nuclear weapons.Though this was the first step in a career that saw Wilkinson become a professor at Oxford University (1957-76) and vice-chancellor of Sussex (1976-89), it almost took a quite different direction. In Canada, Wilkinson’s job was to monitor neutrons in the reactor. This proved nearly fatal, as he got radiation sickness, his white blood count fell, and he was given six months to live. Having recovered, and back in Cambridge, for a time afterwards it looked as if he probably would not be able to go back to nuclear physics. He became interested in a mystery of bird migration, and applied to the problem analysis techniques that he had learned from nuclear physics to solving it. Continue reading...

Why is finding a therapist so hard? Meet the mental health matchmaker
Finding someone to connect with can be draining – much like dating – and Dr David Kelley wants to help. Jean Hannah Edelstein investigates“You should try therapy!” is a suggestion that I realized, after maybe too long, most people don’t take as a compliment. I think therapy is great: what thoughtful, smart person wouldn’t benefit from taking some time for careful examination of their feelings and how they interact with the world? No thoughtful, smart person, in my opinion. Deciding to go to therapy isn’t an admission of fault: it’s an admission of the desire to be happier, less anxious and more at ease.But even if you are the kind of thoughtful, smart person who can overcome the stigma against seeing a professional to talk about your problems, there’s another major hurdle to surmount: it can be very difficult to find the right therapist. Much as with dating, for therapy to succeed, you need to find someone with whom you want to spend a lot of time talking about yourself (unlike dating, however, you should definitely not have sex with your therapist). As with dating, looking online (Psychology Today has the most popular database) and going through a trial and error process can be emotionally draining, especially if you’re feeling sad or anxious already and lack the energy to interview a lot of different therapists before you hit the right one.

Stretchy 'second skin' could make wrinkles a thing of the past
Wearable film improves skin’s elasticity, reduces appearance of wrinkles and could be used to cover birthmarks or treat conditions such as eczemaFor those concerned about wrinkly old skin, it might be an ingenious solution: a stretchy “second skin” that can be smoothed on to make aged tissue look more youthful.The wearable film developed at Massachusetts Institute of Technology has shown promise in a series of small trials where it was applied to wrinkles, under-eye bags and patches of dry skin.

Transit of Mercury: what you need to know and how to watch it
The smallest planet passes the face of the sun today. Here’s what you need to know and how you can watch it safely.The transit of Mercury across the face of the Sun on Monday 9 May is the first for the planet since 2006 and the first to be visible from Britain since 2003. Our next occurs in 2019, but we must wait until 2049 for a more favourable one than this.We might think that the little innermost planet would cross in front of the Sun every 116 days or so, every time it swings around the near side of its orbit of the Sun. However, that orbit is tilted at 7° to that of the Earth, so Mercury usually sweeps unseen above or below the Sun when it is closest, at its so-called inferior conjunction. The next most inclined orbit is that of Venus at 3.4°. Continue reading...
Before the Transit of Mercury: forgotten forerunners of an astronomical revolution | Karl Galle
A manuscript note in the Royal Society Library hints at an observing program that would eventually transform our ability to predict the motions of the planets.“Today I saw Mercury.” This terse remark scrawled inside a 16th-century almanac could reflect anyone watching today’s transit of Mercury across the Sun. The winding path this observation took after it was recorded, however, traces a century-long story leading through the transformation of both our understanding of the cosmos and the practice of astronomy itself.Mercury’s observer in this case was Willibald Pirckheimer, a German humanist who made diary notes in a set of astronomical tables by Johannes Regiomontanus, which are now preserved in the Royal Society Library. Pirckheimer almost certainly wasn’t alone, as the same Mercury sighting (early in the evening of 18 March 1504) was recorded in more detail by his friend Bernhard Walther, who had inherited Regiomontanus’ observation program and copious manuscripts. Perhaps it was solely an observing session, or perhaps it preceded one of the festive banquets Nuremberg’s humanists were known for. We may not know the evening’s full itinerary, but it’s a reminder that science was rarely a solo activity even back then. Continue reading...

The 100 best nonfiction books: No 15 – The Double Helix by James D Watson (1968)
An astonishingly personal and accessible account of how Cambridge scientists Watson and Francis Crick unlocked the secrets of DNA and changed the worldJim Watson was just 24 when, in collaboration with Francis Crick, he decoded the structure of DNA, “the molecule of life”. This was a 20th-century watershed, the solution to one of the great enigmas of the life sciences that would revolutionise biochemistry. In human history, without exaggeration, nothing would ever be the same again.Watson arrived at the Cavendish Laboratory, Cambridge University, during the autumn of 1951 looking for success, fame and the love of women. He was brash, brilliant and American; a graduate zoologist from the mid-west who dreamed of winning the Nobel prize. Watson, as arrogant as he was obscure, found himself working with an equally self-possessed but somewhat overlooked older man at the Cavendish, Francis Crick, a 35-year-old would-be biophysicist who had seen service as a scientist in the second world war. In his breezy, tactless way, Watson describes his new colleague as “totally unknown [and] often not appreciated. Most people thought he talked too much.” Continue reading...

Harry Kroto: scientist with a common touch | Letters
In a year when we mourn the loss of many national treasures, I reflect with great sadness on the passing of Nobel prize-winning chemist Harry Kroto.Harry was an alumnus of Bolton School, where I was studying when I had the good fortune to hear him accept the Dalton Medal at Manchester University in 1998. His story of scientific discovery and down-to-earth demeanour inspired me to pursue a career in science, but something he said that night has stuck with me even more. He spoke about the value, indeed the necessity, of communicating complex science to public audiences: “Scientific discoveries matter much more when they’re communicated simply and well – if you can’t explain your work to the man in the pub, what’s the point?” Continue reading...
The Guardian view on artificial intelligence: look out, it’s ahead of you | Editorial
There is a tendency to see intelligence where it does not exist. But it is just as wrong to fail to see where it is emergingGoogle artificial intelligence project DeepMind is building software to trawl through millions of patient records from three NHS hospitals to detect early signs of kidney disease. The project raises deep questions not only about data protection but about the ethics of artificial intelligence. But these are not the obvious questions about the ethics of autonomous, intelligent computers.Computer programs can now do some things that it once seemed only human beings could do, such as playing an excellent game of Go. But even the smartest computer cannot make ethical choices, because it has no purpose of its own in life. The program that plays Go cannot decide that it also wants a driving licence like its cousin, the program that drives Google’s cars. Continue reading...
The embryo rule shows how much our leaders can learn from science | Deborah Orr

Lilly Dubowitz obituary
Paediatrician, neurologist and author whose work revolutionised the assessment of newborn babiesIn the early 1970s, a husband and wife team developed two novel clinical tests that revolutionised the way newborn infants are assessed in clinical and research practice around the world. One was for determining gestational age; the other for the systematic neurological examination of the newborn. The scientists were Victor and Lilly Dubowitz. Lilly, who has died aged 85, was a leading figure in the field of neonatology, and her pioneering work spanning more than 40 years is internationally recognised. The Dubowitz score and the Dubowitz neonatal examination have been used by generations of neonatologists and paediatric neurologists.The assessment of gestational age in the newborn infant, developed with Victor and published in 1970, was immediately adopted worldwide as a way of distinguishing small babies who were mature but malnourished from those who were premature and of appropriate small size. It measured some neurological signs, such as the infant’s ability to flex and extend its joints and limbs, and also some superficial signs, examining the skin, eyes, ears, genitals and other physical characteristics for signs of maturity. From these, after the examiner had matched the infant’s responses with the options on an illustrative chart, came the Dubowitz score. The beauty of the test was that it was simple and easily recorded through clinical observation. Continue reading...
Charles Thomas obituary
Archaeologist with a particular passion for the history of his native CornwallCharles Thomas, who has died aged 87, was an outstanding scholar of early Britain, with an international reputation. He researched and published widely about Cornwall, its local history, its archaeology and religion, its language, dialect, customs, folklore and humour, its art and artists, its military history and its relationship with other Celtic nations. He was also a nonconformist in every sense: a committed Methodist and a founding member of Mebyon Kernow, the Cornish nationalist party.I first met Charles in July 1955, when I was mistakenly the first volunteer to arrive on an archaeological excavation. Charles seized the moment, gave me a yard-broom, peremptorily told me to clean up one of the dilapidated Nissen huts in which we were to live – and disappeared. I later appreciated that this was typical Thomasian behaviour, and why some found him abrupt and even arrogant; in fact he was shy. Above all, he was kind and a marvellous encourager, especially in the field. Continue reading...

Aarathi Prasad: ‘Indians hedge their bets’
In a fascinating book about medicine in India, Aarathi Prasad describes a push to integrate the modern ‘western’ approach with many traditional systems, from ayurveda to yoga. But is this truly desirable – or even possible?With a PhD in molecular genetics, author Aarathi Prasad works in interdisciplinary research at University College, London. Her first book, Like a Virgin: How Science Is Redesigning the Rules of Sex, was published in 2012, exploring how inventions such as the silicone womb could change the future of reproduction. Her latest book, In the Bonesetter’s Waiting Room: Travels Through Indian Medicine, examines the diverse treatments on offer in the country’s cities and rural communities, and the future of Indian healthcare.In India there are two broad approaches to medicine: conventional “western” medicine and traditional practices, which go under the banner of Ayush. What are these practices?

The coming refugee crisis: when home leaves us | Vicki Arroyo
Louisiana’s sinking Isle de Jean Charles shows the urgent need for measures to combat climate changeAs seas rise, as floods and droughts become more extreme, as crops fail and as storms intensify, the world will increasingly face a new challenge – climate refugees.In the US, witness the recent plan by the federal government to resettle a Native American tribe before their Isle de Jean Charles home in Louisiana vanishes underwater – an example that hits close to home. I have deep family roots in south Louisiana: my mother, sister and brother-in-law, aunt and uncle were refugees from a weather disaster exacerbated by climate change, losing their homes in New Orleans during Hurricane Katrina in 2005. A year before, a heart condition killed my father in the aftermath of a stressful evacuation from Hurricane Ivan. Continue reading...

'Slapped for spice': how synthetic cannabis is wreaking havoc behind bars
Sam Johnson is schizophrenic, in prison, and now dependent on synthetic cannabis. As inmates like him contend with violence and debt, and overdoses spiral, observers are warning that the system is facing a drugs crisisThe Johnson family used to think nothing could shock them. Then they received a short video on Snapchat of 38-year-old Sam Johnson being beaten up by fellow inmates at Guys Marsh prison, Dorset.Johnson, who is serving a 32-month sentence for robbery, is schizophrenic and has learning disabilities. He is also a drug addict. After his latest stint in jail, it would appear he is now dependent on synthetic cannabis, a family of legal highs that are wreaking havoc in Britain’s jails. Sold under dozens of brand names, synthetic cannabis is known generically as Spice, after an early market leader. Continue reading...

It’s time to extend the 14-day limit for embryo research | John Harris
A switch to a 21-day deadline would allow scientists to better understand miscarriages and the possibilities of using stem cells to treat diseasesThe 14-day rule for permissible embryo research was conceived by the philosopher Mary Warnock as an answer to the question, always raised in relation to controversial science, of “where to draw the line”.The somewhat curious reason for this cut-off was that the individual soul could not be bestowed by God on an individual who might turn out to be two individuals. Fourteen days was the point at which an embryo could no longer split into two identical twins, requiring two souls and not just one soul between them. This was said to be the point at which the individuality of an embryo is assured, because it can no longer become two people. Continue reading...
Transit of Mercury: 'a chance to feel part of the solar system in motion'
Monday’s transit of Mercury will see the solar system’s smallest, fastest planet cross the face of the sun, watched by astronomers worldwideAstronomers around the world are making final preparations for the transit of Mercury on Monday when the smallest and fastest planet in the solar system crosses the face of the sun.Though little more than a slow-moving dot, the celestial event has enormous historical importance. When the English astronomer Edmund Halley observed the 1677 transit in the skies above St Helena, he saw a way for scientists to measure the cosmos.
Don’t think you’re lucky? Think again | Oliver Burkeman
You probably think you got where you are today through willpower and elbow grease. But what about chance, asks Oliver BurkemanDo you feel lucky? The answer, well known to psychologists, is that you probably don’t. You probably think you got where you are today through willpower and elbow grease. We chronically underestimate luck’s role, and this seems to get worse the richer we get; surveys show that the wealthiest are least likely to attribute their fortunes to, well, good fortune. They also seem to be meaner: one ingenious study found drivers of luxury cars were more likely to cut others off than those in cheaper vehicles.It’s hardly surprising many such people oppose taxation and government spending: why should others get a handout if they didn’t need one? The ironic result is that they vote against the very policies that helped them get lucky to begin with. In a recent Atlantic essay, Robert Frank, an economist who has studied attitudes to chance, quoted EB White: “Luck is not something you can mention in the presence of self-made men.” Continue reading...
Amazon and eBay hosted ads for banned invasive species
Unregulated traders are using the sites to sell some of the world’s most invasive plants, with potentially devastating impacts on ecosystemsAmazon and eBay appear to have openly broken the law by hosting listings to ship banned invasive species to the UK, the Guardian can reveal.Both eBay and Amazon have previously been criticised for hosting ivory traders, but the UN Convention on Biological Diversity (CBD) rates invasive species as a more significant threat to biodiversity than poaching for animal parts. In February, the CBD said there was an “urgent need” to control the vast, unregulated network of online traders who buy and sell these pests across the globe. Continue reading...
Does an AI need to make love to Rembrandt’s girlfriend to make art?
Is a picture made by an artificial intelligence ‘art’ if there’s no emotion involved? And what happens if you train a neural net to make music using only the Friends theme tune?Jonathan Jones is unhappy about artificial intelligence. It might be hard to tell from a casual glance at the art critic’s recent column, “The digital Rembrandt: a new way to mock art, made by fools,” but if you look carefully the subtle clues are there. His use of the adjectives “horrible, tasteless, insensitive and soulless” in a single sentence, for example.

Why do some of us, like David Attenborough, live to 90? It’s not luck | Alan Walker
The great television presenter and the Queen are celebrating becoming nonagenarians. But there’s nothing random about their health and longevityDavid Attenborough is wrong (a sentence I thought was impossible to write). But when he told the Guardian earlier this week that the reason he had reached the age of 90 was down to luck, he was very wide of the mark.Of course, being Attenborough, he could not be completely mistaken, and he did put his finger on a defining feature of later life: inequality. “When you think, I have relatives and friends who are 90 and they can’t remember what day it is and they can’t walk – this is not Christian virtue, just luck.” Well, it isn’t.

Virtual reality isn't just for gaming - it could transform mental health treatment
The results of our experiment paint a very striking picture of the power of therapy involving VR in treating patients with persecutory delusionsIf you haven’t yet heard about Oculus Rift, chances are you soon will. Virtual reality (VR) headset technology – in the form of the Oculus and its main competitor the HTC Vive, both of which have just been launched on the consumer market – is about to make the leap into the mainstream. For the gaming industry, big bucks are in the offing. Facebook paid £2 billion to acquire Oculus Rift ; the returns, one imagines, could swiftly dwarf that figure.VR may be about to transform gaming, but the technology dates back to the late 1960s and the so-called Sword of Damocles. Bulky and relatively unsophisticated though it was, the main elements of VR were all present in the Sword. A computer generated an image, a display system presented the sensory information and a tracker fed back the user’s position and orientation in order to update the image. For the user, sensory data from the natural world was superseded by information about an imaginary world that changed in response to their actions. The result was what you’d experience with Oculus Rift or the Vive today: a “sense of presence” in an interactive, three-dimensional virtual world.
Sir Harry Kroto obituary
Chemist who won the Nobel prize for his role in discovering buckminsterfullerenes, also known as ‘buckyballs’Sir Harry Kroto, who has died aged 76, was awarded the Nobel prize in chemistry in 1996 for his part in the discovery of buckminsterfullerenes, also known as “buckyballs” – carbon atoms found in the form of a ball. In 1985 Harry, then professor of chemistry at the University of Sussex, had teamed up with Rick Smalley and Robert Curl, both professors of chemistry at Rice University, in Houston, Texas, to laser-vaporise carbon in laboratory experiments designed to simulate the chemistry of stars and interstellar space. Their experiments appeared to indicate that they had made an unexpected molecular species comprising 60 carbon atoms. This was amazing. Carbon had long been known to exist as diamond or graphite, but carbon as a small molecule required completely new thinking.This was where Harry drew on his artistic side and a knowledge of graphic design: he proposed that C was made up of a mixture of pentagons and hexagons, a structure known in ancient times, and now ubiquitous in footballs and in the work of the US architect and inventor Buckminster Fuller. But at first nobody could prove it, and many were openly sceptical. Continue reading...

Seven lucky ways that gambling changed maths
Gambling is the vice that helped make the modern world. Here mathematician Adam Kucharski explains how casinos and card games inspired many ideas that are now fundamental to science.1. Dice games and the birth of a new scienceIn the 16 Century, there was no way to quantify luck. If someone rolled two sixes during a game of dice, people thought it was just good fortune. Gerolamo Cardano, an Italian physician with a lifelong gambling habit, thought otherwise. He decided to tackle betting games mathematically, and wrote a gamblers manual that outlined how to navigate the ‘sample space’ of possible events. For example, while two dice can land in 36 different ways, only one of these produces two sixes. Continue reading...

Large human brain evolved thanks to increased metabolic rate
A shift in metabolic gear in our ancient ancestors means that humans burn calories much faster than any other primate, giving us energy for larger brainsThe hefty brains that set humans apart from other apes came into being when our ancient ancestors massively ramped up their metabolism, scientists say.The shift in metabolic gear, after the human lineage split from other primates, gave humans enough energy to run larger brains, have children in rapid succession, and live longer lives, the researchers found.
