Heavily armoured dinosaur had ginger camouflage to deter predators – study
Analysis of organic material from the 110m-year-old nodosaur suggests it had red and white camouflage, indicating its spikes alone did not put off predatorsIt was built like a tank, covered in armour, and weighed about the same as a caravan – but this beefy dinosaur was still at risk of being gobbled up by predators, scientists have discovered.Thought to have lived about 110m years ago, the giant herbivore is believed to be a type of heavily armoured dinosaur known as a nodosaur and would have reached up to 5.5 metres in length.
Gene editing isn’t about designer babies, it’s about hope for people like me | Alex Lee
What gives someone without an incurable condition such as blindness the right to stand in the way of potentially life-saving treatments?A landmark US study by scientists at Oregon Health and Science University in Portland has for the first time successfully edited out a genetic mutation that could cause heart disease, but the fearmongering over designer babies rages on. Where would research into cures for genetic diseases be without a good old debate around the scary future of eugenics?For once, let’s not allow that rhetoric to take over the headlines, in the way that it did two years ago, when research into mitochondrial replacement therapy, so-called three-parent babies, made strides. This is a good and promising breakthrough, not something to fear. Continue reading...
Royal Society science book prize shortlist tackles 'the big questions'
Judges hail writers’ blend of eloquence and erudition on subjects ranging from the evolution of the octopus to the impact of technology on modern manFrom the vastness of infinity to the microbes that live within us, the shortlist for the Royal Society Insight Investment science book prize tackles “the big questions of our time”, according to chair of judges Richard Fortey.Palaeontologist and writer Fortey, with his fellow judges, read almost 200 books to come up with their lineup of six, which ranges from In Pursuit of Memory, Joseph Jebelli’s look at the quest to find a cure for Alzheimer’s, to Peter Godfrey-Smith’s Other Minds, which explores the evolutionary journey of the octopus. Also shortlisted are Cordelia Fine’s study of gender politics, Testosterone Rex, which tackles the myth that sex creates male and female natures and Mark O’Connell’s To Be a Machine, looking at how technology is changing the human condition. Completing the field are Eugenia Cheng’s Beyond Infinity, a study of the concept of infinity, and Ed Yong’s I Contain Multitudes, about the microbes in our bodies. Continue reading...

From bae to millennial, 11 words that make the heart sink
The 5,000 funniest words have been revealed, but drop ‘gamification’ at a party and you may as well say ‘TED talk for one’Comedy is simple. Just give an egghead a tinkle, get them to waddle over to play some bebop on a twerp’s ass, and you’ve got yourself a laugh riot. Psychologists at the University of Warwick recently asked 800 people to rate 5,000 word on which were the most inherently comic. They include the aforementioned “waddle”, “bebop”, “twerp”, “ass”, “tinkle” and “egghead” (imagine, a man with an egg for a head!). Less predictably, it turns out that men and women find different words funny: “buzzard” and “czar” make the male charts, as do sex words such as “orgy” and “bondage”. Women – those demure little puddings – prefer “giggle” or “sweat”. If those are the words that make us puncture lumbar regions with guffaws, what about their opposites: those words that make the heart sink? Well, we can think of a few.Dunkirk Hot take incoming.

Lessons for Brexit negotiations from 60 years of Britain and Euratom
The miscalculation politicians have always made in negotiating European treaties is that we’ll be welcomed with open arms. Time for a history lessonUntil recently, few of us were familiar with the European Atomic Energy Community (Euratom), the international organisation that governs many aspects of nuclear energy activity in member states. Brexit, and the rapidly retracted “leak” that Britain may seek “associate membership” of Euratom has suddenly brought Euratom to the fore. The precise legal situation regarding the UK’s continued membership of Euratom is contested, but there is much to learn from the history of this relationship: over the past six decades the UK has attempted to become an associate member or full member of Euratom five times.

Jump for joy: researchers make huge leap in understanding frog evolution
A new analysis using an unprecedented dataset reveals that major changes in frog diversity are linked to mass extinctionsAlthough Kermit the Frog has always struggled with body image, in evolutionary terms, the frog body plan is a rather successful one. With a short, stout body, protruding eyes and strong, flexible limbs with webbed feet, the world can be your swamp. The frog body plan has remained rather similar for almost 200m years, and with only limited tweaks in anatomy, frogs (Anura) have managed to occupy a range of different habitats, from muddy pools in Alaska to tree tops in the tropics. Currently, over 6700 species are known from all continents except Antarctica, which makes frogs one of the most diverse and species-rich groups of tetrapods. Never change a good thing. However, this limited variation in the frog body plan over time and space has made it difficult for biologists to reconstruct the evolutionary history of frogs and to sort out who is related to who.

Jodrell Bank's heritage celebrated with listed status for telescope and buildings
Celebrating 60 years of the Lovell Telescope, Historic England has listed other parts of Jodrell Bank to honour the landmark research conducted at the siteIt is 60 years since the first great Jodrell Bank telescope was trained on the skies to peer into the secrets of the universe. To flag up the international importance of this landmark in science history, a modest collection of nondescript industrial sheds, as well as the second of the giant radio telescopes they were built to serve and the remains of a huge aerial adapted from wartime technology, are being given listed building status by Historic England.The Lovell Telescope has had the highest Grade I listing since 1988. The first giant telescope on the Cheshire site, it was built after Sir Bernard Lovell took his observatory from the murk and radio interference in the centre of Manchester to the clearer skies of Cheshire. The Mark I telescope – renamed the Lovell in his honour – was the first of its kind in the world, and with a height of just under 90 metres is still the third largest. Continue reading...
'Southern' English language course for foreign teachers – archive, 1922
2 August 1922: Foreign pupils will learn to say a good, straightforward “nice” and an honest “time,” and will not attempt the popular “naice” and “taime”If Chaucer could come back to earth and attend the vacation course in English phonetics for foreign teachers of English which commenced at University College to-day he would probably understand less of the explanations than say, the visitors from Egypt and Czecho-Slovakia, who are attending in force.

Ejaculation statistics are hard to pull off | Letters
Suzanne Moore states that the average man ‘produces 14 gallons of ejaculate in a lifetime’. That can’t be right, argues Andrew BarnardIn her article (Making babies is beginning to look as difficult for men as it always has for women, 27 July), Suzanne Moore states that the average man “produces 14 gallons of ejaculate in a lifetime”. One doesn’t have to be Einstein to work out that 14 gallons of semen would require 12,740 ejaculations of five millilitres volume (the oft-quoted average). This would mean an average of just over four ejaculations per week, every week for a 60-year period (or five per week over 50 years, etc), say from early teens to early seventies. This seems unlikely. Perhaps Ms Moore is confusing gallons with litres – 14 litres produces rather more believable averages. I think that some proper checking of journalists’ figures is required.
Should we stop keeping pets? Why more and more ethicists say yes
Ninety per cent of Britons think of their pet as part of the family – 16% even included them on the last census. But recent research into animals’ emotional lives has cast doubt on the ethics of petkeepingIt was a Tupperware tub of live baby rats that made Dr Jessica Pierce start to question the idea of pet ownership. She was at her local branch of PetSmart, a pet store chain in the US, buying crickets for her daughter’s gecko. The baby rats, squeaking in their plastic container, were brought in by a man she believed was offering to sell them to the store as pets or as food for the resident snakes. She didn’t ask. But Pierce, a bioethicist, was troubled.“Rats have a sense of empathy and there has been a lot of research on what happens when you take babies away from a mother rat – not surprisingly, they experience profound distress,” she says. “It was a slap in the face – how can we do this to animals?” Continue reading...
We'll never tackle climate change if academics keep the focus on consensus | Warren Pearce
Media and political attention is being wasted on boosting the public’s notion of scientific consensus, crowding out more important discussion and actionIn a democracy, we hope that science helps to inform the public about its problems. In the case of climate change, believe it or not, the evidence suggests this is going relatively well.Climate science is a vast, sprawling field of knowledge that has achieved great success in occupying the public consciousness. According to Yale University’s Climate Change in the American Mind project, six in ten Americans are worried about global warming, seven in ten think global warming is happening and eight in ten think humans have the ability to reduce global warming. These figures have fluctuated very little since 2012, suggesting that the US public is relatively well informed about the risk, reality and policy potential of climate change, even in the face of well-documented attacks by climate sceptics.

Break down barriers to breastfeeding in the UK | Letters
The government must take the lead on ensuring that terms of employment do not deter women who wish to breastfeed and social attitudes must also improve, write Neena Modi and 17 other signatoriesThe evidence that breastfeeding has long-lasting benefits for infant and mother is clear. Further, though some women are unable to breastfeed and some choose not to, with the right support, the vast majority of women are able to breastfeed successfully.So why is it that over 73% of mothers in England initiate breastfeeding but by six to eight weeks this figure has dropped to just 43%? To give this some perspective, in Norway the figure at six months is 71%. Continue reading...

'There are things worse than death': can a cancer cure lead to brutal bioweapons?
John Sotos, chief medical officer at Intel, paints a dark picture of technology turned to nefarious purposes, with tailored diseases rewriting genomes on the flySplitting the atom brought humanity nuclear power and nuclear weapons. A cure for cancer could have the same potential for pushing humanity to new highs – or terrifying lows. According to John Sotos, the chief medical officer of Intel, the same technology that might someday allow us to defeat illness for good also poses the prospect of tailored diseases attacking individuals, families or even whole races and rewriting their genomes on the fly.Sotos made his remarks at the DEF CON hacking conference in Las Vegas, a place where hackers gather to share tips and tricks for how to break into almost anything with a circuit board. But during a weekend when attacks were demonstrated against wind farms, voting machines and almost every major smartphone in one fell swoop, Sotos’ nightmare scenario still stood out as plausible and terrifying.

Follow professional advice on antibiotics | Letters
The idea that patients should stop taking antibiotics ‘when they feel better’ is too subjective, say representatives of the British Society for Antimicrobial ChemotherapyWe welcome the debate sparked by your article (Keep taking the tablets? Antibiotics rule could be wrong, 27 July). The British Society for Antimicrobial Chemotherapy (BSAC) is keen to safely reduce the overall use of antibiotics, given that “overuse” is helping to drive the alarming rise in so-called superbugs.We, like others, suspect that a significant number of antibiotics are being prescribed for longer than is necessary. However, the idea that patients should stop taking antibiotics “when they feel better” is too subjective and risks treatment failure or relapse. Most patients simply will not know if the cause of their infection has been eradicated – or not. Two things need to happen urgently: research to identify (1) all those infections that do not need to be treated with antibiotics, and (2) the most effective length of treatment for those infections that do.

Want to sound cleverer than Jacob Rees-Mogg? Here are five long words to drop into conversation
The record for the longest word spoken in parliament has been broken with pneumonoultramicroscopicsilicovolcanoconiosis – but there are plenty of alternativesIs this the first sign of Moggmentum draining away? We can but hope. Jacob Rees-Mogg, the MP for North East Somerset and the 18th century, has been knocked off his perch as utterer of parliament’s longest word. Michael Bryan’s use of “pneumonoultramicroscopicsilicovolcanoconiosis” in a select committee meeting means floccinaucinihilipilification’s reign – it has been a mere five years since Rees-Mogg said it during a Commons debate – is over. Whether Bryan will follow through on this promising start by naming his future children after numbers is yet to be seen. He’s only 16, which means there’s plenty of time for a course correction if the position of National Fogey loses its appeal. In the meantime, here are five words you can slip into conversation if you want to put in a bid yourself. Continue reading...

Can you dig it? What to do if you find a Stegamastodon
These are the steps to follow if you make a museum-worthy discovery – like the nine-year old who uncovered a 1.2m-year-old animal skull in New MexicoWhen so many relics are stumbled on by accident, it is a wonder that specialists still bother digging around in books, rather than just going for a wander. Indeed, New Mexico State University recently revealed that it received a call last year from the parents of nine-year-old Jude Sparks, who had literally stumbled over a 1.2m-year-old fossil. Sparks was out walking with his family in Las Cruces, New Mexico, when he tripped over something jutting out from the earth. He thought it was the skull of a “big fat rotten cow”, but biologist Prof Peter Haude determined that it belonged to a Stegomastodon – a distant relative of the elephant, and similar to a mastodon. The university estimates that the process to study and reconstruct the skull, jaw and tusks will take several years to complete.If Jude’s story has inspired you, you might want to follow these tips provided to the Guardian by Prof Paul Barrett, president of the Palaeontographical Society and a researcher at the Natural History Museum. “Finding fossils is a mixture of pure chance and careful planning,” says Barrett. “It takes a keen eye and lots of looking at the ground to see those that erosion has started to uncover.” Continue reading...

How to conquer our obsession with eternal life | Matt Haig
Our anti-ageing quest only increases anxiety, says Matt Haig. Instead, we need to understand the tricks of timeAs a culture, we are obsessed with ageing. We have always been obsessed but now, paradoxically, in an era where we live longer than ever, we fear it more than ever before too. There is, of course, a whole industry devoted to capitalising on our fears of the natural ageing process and it’s a lucrative one. In fact, the anti-ageing industry, which is the largest part of the beauty industry, is now worth more than $200 billion a year.Our perfectly understandable worries about time and mortality are being capitalised on, and exploited. Every advert that encourages us to look young is confirming the same thing: we need to fear growing old. And yet no anti-wrinkle eye cream in the world is going to stop us from getting old. The anti-ageing industry is a marketer’s dream because it is an industry offering continual solutions for something that isn’t ever really solved. Ageing. Continue reading...

The world has lost a great artist in mathematician Maryam Mirzakhani
She was the only woman to have won the Fields medal, maths’ equivalent of the Nobel prizeThe mathematician Maryam Mirzakhani died two weeks ago. She was 40. I had never heard of her before reading about her death in the papers. It’s a piercingly sad story: Iranian-born, and latterly a professor at Stanford University, Mirzakhani was the only woman to have won the Fields medal, the equivalent for a mathematician of the Nobel prize, and is survived, in newspaper-speak, by a husband and a daughter.I always find the locution “survived by” too cruel to bear. So final the rupture, no room for error: she’s gone, they’re left. And, in this case, how young the mother and the wife. Continue reading...

The Goldwater rule: why commenting on mental health from a distance is unhelpful
Is it okay to speculatively diagnose public figures like Trump? No, says the Goldwater rule – and recent challenges to it could set worrying precedentsThis week the Goldwater rule has come into focus – the convention that psychologists should not give an opinion about the mental state of a person they have not examined. Recently, the American Psychoanalytic Association (APsaA) emailed its members to remind them that they as individual practitioners are not bound by the Goldwater rule (which is a rule of the American Psychiatric Association, APA), and that they should feel free to offer fact-based but non-specific assessments of public figures - figures like Donald Trump.
Lab notes: we are starlight, we are slug slime ...
Proving that Joni Mitchell is one of the greatest astrophysicists of our time (followed closely by Moby, obviously,) simulations have revealed that up to half the material in our home galaxy – and by extension in our bodies – arrived from smaller galactic neighbours, as a result of powerful supernova explosions. Add to this the news that the moon is wetter than we thought, which raises new possibilities for lunar exploration, and frankly, I’m starting to feel positively intergalactic. Back here on Earth, however, the picture is a mixture of optimism and concern. On the one hand, an extremely exciting piece of research (described as a “tour de force” by one expert, so there you go) has shown that the hypothalamus controls ageing, and that implanting stem cell from it into the brains of mice slowed their rate of ageing and kept them mentally and physically fit for longer. They’re hoping to conduct human trials soon. So far so life-affirming, but on the other hand we have the rather worrying news that sperm counts among western men have halved in last 40 years. Nobody seems to know why, and it appears that this is partly because men’s reproductive health is a rather neglected area. Researchers have also found a strong association between consuming higher levels of sugar and depression in men (a link not seen in women). Looks like we need to start paying better attention to men’s health – mental and physical – or all that extra old age spent bouncing around our moon colony is going to be no fun at all.

Trust me on antibiotics, doctor – I’m a patient | Anne Perkins
Evidence that finishing the course may fuel bacterial resistance will test our relationship with experts – and perhaps begin the healing process
The Guardian view on antibiotics: don’t keep taking the tablets | Editorial
When knowledge advances, so should the advice doctors giveThe idea that we have a moral duty to complete any course of antibiotics that the doctor prescribes is intuitively comforting. Following the course to the end appears as an act of solidarity against the genuinely terrible threat of widespread antibiotic resistance, something that could make medicine as we know it impossibly dangerous. Following the doctor’s orders allows us to be mildly uncomfortable in pursuit of collective good. So it is rather shocking when the British Medical Journal reports that the instruction is mistaken and indeed counterproductive. We should not only take antibiotics less often; we should take them for much less time.Nonetheless, the argument of the BMJ paper is very strong. It starts from history. At the beginning of the antibiotic era, the danger to patients came from insufficient dosage, not from too much. The very first patient ever treated with penicillin died after supplies ran out, even when they were recycled from what he had already consumed. Sir Alexander Fleming himself believed that antibiotic resistance would be stimulated by inadequate courses of antibiotics. In any case, there are compelling legal and social reasons why doctors are more worried about being accused of doing too little than too much. Continue reading...
From goo to glue: slug slime inspires new wound-mending surgical adhesive
Impressed by the sticky and elastic properties of slug mucus, researchers have developed tough, flexible glues that can even work on bloody, moving tissueIf there are two words in the English language likely to trigger a curl of the lip, “slug mucus” would be towards the top of the list. But while the molluscs and their slimy secretions are the bane of the green-fingered, it seems they have triggered a moment of inspiration in the laboratory.
Marion Macleod obituary
My mother, Marion Macleod, who has died aged 86, was an academic microbiologist and medical sociologist. She was also a fine example of the benefits of the postwar policy of opening up higher education to bright students from all backgrounds.Marion was born in Newcastle upon Tyne, the daughter of Roland Fairman, a coach painter, and his wife, Rhoda (nee Finch), a cleaner. The family lived in a shared terraced house with no bathroom and an outside toilet. Evacuated at the outbreak of the second world war, Marion was sent first to Berwick-upon-Tweed and then to Shap in Cumberland (now Cumbria). On returning to Newcastle, economic pressure forced her to leave school and start work aged 16, as a technician in a bacteriology laboratory at Newcastle University. She continued her school studies at evening class and won a university scholarship. Continue reading...
