Are gut microbes really a panacea, or just overhyped? | Mo Costandi
We are beginning to unravel lines of communication between gut and brain. But don’t hold your breath for the probiotic that will lift your moodHistorically, microbes have been associated with deadly diseases such as bubonic plague, smallpox and malaria. But they have had a bad press: only a tiny minority are pathogenic (capable of causing disease), and in fact many of the microbes that live on and in our bodies – especially the trillions of bacteria residing in our gut – may be beneficial, or indeed essential, for human health.Related: Organisms created with synthetic DNA pave way for entirely new life forms Continue reading...
Mysticism and rudely-shaped rocks: why 17th-century palaeontology is worth revisiting
It may deviate into descriptions of giant humans and Noah, but Robert Plot’s 1676 work demonstrates how current research is based on generations of workIn the history of dinosaur palaeontology, naturalist and chemist Robert Plot, is credited as making the earliest (surviving) description and illustration of a dinosaur fossil. In the rather verbose The Natural History of Oxfordshire of 1676, addressed to King Charles II, Plot systematically records his observations of the heavens, air, waters, earths, stones, plants, men, women, arts and animals of Oxfordshire.Chapter five of the book is about “Formed Stones” and it’s in this chapter that the “first dinosaur” is recorded. In a section describing formed stones reminiscent of the parts of humans, Plot describes and illustrates a stone in “... the figure of the lowermost part of the thigh-bone of Man or at least some other Animal ...” but larger in proportion than a horse or ox and different and smaller than an elephant. With some suspect deduction, Plot suggests that this must be from a giant man or woman and then gives an exhaustive account of giants known from history. Continue reading...

By creating a market for universities, the government has snookered itself
Shortsighted politicians are reaping the consequences of an unsustainable market in higher education that they themselves createdThe government has a problem. Open any newspaper or turn on the news and there are items about the cost of universities and the burden of debt on students, at levels higher than the cost of most of their parents’ first house.People are complaining about universities at a time when the present government thought it had the issue sorted. The creation of a full-blown market for higher education with its own regulator – the Office for Students – heralded by the recent Higher Education and Research Act, is now nearly complete. The theory was that competition amongst the hundred or more existing universities, and a raft of new commercial providers, would hone the system to perfection. Continue reading...
Supersize us: upselling is fuelling the obesity epidemic, warns report
Consumers persuaded to scale up a meal or drink take on an extra 55% more calories on average – and a big annual weight gain, experts revealOne in three people buys a larger coffee, more fries or added cream each week as a result of “upselling”, which experts say is fuelling the obesity epidemic.Most people in the UK – 78% of those questioned in a survey – say they are asked in restaurants, fast food outlets and stores at least once a week if they want to “go large”, opting for more food or bigger portions, according to a report.

Climate change could wipe out a third of parasite species, study finds
Parasites such as lice and fleas are crucial to ecosystems, scientists say, and extinctions could lead to unpredictable invasionsClimate change could wipe out a third of all parasite species on Earth, according to the most comprehensive analysis to date.Tapeworms, roundworms, ticks, lice and fleas are feared for the diseases they cause or carry, but scientists warn that they also play a vital role in ecosystems. Major extinctions among parasites could lead to unpredictable invasions of surviving parasites into new areas, affecting wildlife and humans and making a “significant contribution” to the sixth mass extinction already under way on Earth.

Writers unblocked? Happy music boosts imaginative thinking, say researchers
Uplifting music can help people think more flexibly and avoid getting stuck in a creative rut, say psychologistsJack London hunted it down with a club. Graham Greene found it on benzedrine. For Mary Godwin it struck one wet summer night after making up ghost stories with Lord Byron and her husband-to-be, Percy Shelley.Artists have relied on muses, nature, drink and drugs to fuel their creativity, but according to new research there may be another way to boost imaginative thinking: a blast of happy music. According to psychologists, uplifting music can help people think more flexibly and avoid getting stuck in a creative rut.

The grey zone: reaching out to patients with disorders of consciousness – podcast
In this edition of Science Weekly, Ian Sample explores whether it is possible to communicate with those in a ‘vegetative’ state – and what are the ethical and legal ramifications?Subscribe & Review on Apple Podcasts, Soundcloud, Audioboom, Mixcloud & Acast, and join the discussion on Facebook and TwitterIn 2006, neuroscientists in Cambridge ran brain scans on a young woman who had suffered serious brain damage in a traffic accident. The incident left her in a vegetative state: she slept and woke, but showed no signs of consciousness. But remarkablly, by analysing her brain activity, the scientists found a way to communicate with her. Continue reading...
Research funding is harmful to science – time for change | Jenny Rohn
Researchers seeking science funding can be big losers in the equality and diversity game: will a fresh ethos change this?Yesterday’s launch of the Equality, Diversity and Inclusion in Science and Health Research (EDIS) network is a step in the right direction. Arbitrary barriers that prevent talented people from entering or thriving in the scientific profession – such as gender, race, orientation, disability and socio-economic status – are clearly counter-productive as well as unjust.We are all familiar with the arguments for the positive effects of diversity in STEM. In the UK, the Athena SWAN initiative has gone a long way towards institutionalising a positive approach to leveling the playing field for women in academic institutions, for example.

Rude, erect and smothered in flies, this fungus has no shame
Hawkstone Park, Shropshire The stinkhorn mushroom shares the smell of rotting flesh, making it irresistible to blowfliesThe stench of death, the buzz of flies, the indecent exposure – it was a stinkhorn. Rude, erect and smothered in bluebottles, the fungus was at the side of the path to the follies at Hawkstone Park, though bank holiday visitors paid it little attention.In the 18th century, when this landscape theme park was created, Linnaeus named the fungus Phallus impudicus, literally “shameless phallus”. I imagine visitors then would have been familiar with what the herbalist John Gerard called the “prike mushroom’ in 1597; other folk names included deadman’s cock. Gwen Raverat, the engraver and granddaughter of Charles Darwin (in her 1952 memoir, Period Piece), told a story about her Aunt Hetty (Darwin’s daughter) collecting stinkhorns from the woods and burning them in secret. This was reportedly to protect the morals of the maids but, given Hetty’s neopagan interests, perhaps it was something more fun. Continue reading...
The Guardian view on veganism: high in moral fibre | Editorial
Vegans are often unfairly mocked. They should instead be praisedJeremy Corbyn is “going through the process” of eating more vegan food, he has said – he just has to bring himself to give up the brie, verboten under vegan rules, along with eggs, milk and everything animals produce. Later, as if fearful of a backlash, his spokesperson issued a statement denying he was vegan. But the Labour leader was right to be proud of his efforts. Vegans are often unreasonably mocked as do-gooders and sniped at for making dinner parties awkward for those who don’t like lentils quite so much. This is unfair: the diet does do the world good and if vegans provoke their friends into going vegan too, so much the better.There is now a great deal of convincing data that breeding animals for food dirties the air and chews up the earth. One recent peer-reviewed study from the London School of Hygiene and Tropical Medicine calculates that should the world go vegan, annual greenhouse gas emissions would halve and the new land used every year for each person would near-halve. The diet is also healthier: some meat products have been linked to cancer and saturated fat from meat and dairy products can cause heart disease. A study published in Nature predicts that global veganism would lead to 8.1 million fewer deaths per year. Continue reading...
The secret about human evolution found in spit
Genetic detectives discover surprising findings about our evolution by studying salivaWhat does a protein in our spit called MUC7 that all of us have – but most of us have never heard of – have to do with human history? A surprising amount, as a recent paper by Xu et al. has discovered. Despite being a rather obscure protein to most of us, MUC7 is actually quite important – it helps get rid of bacteria and other junk in our oral tracts.One of the most interesting features of the gene that encodes MUC7 is that it contains a series of repeated DNA sequences (called the “PTS repeat region” for the amino acids these sequences encode: proline, threonine, and serine). Repeated structural elements are a fairly common feature of the genome, and these regions tend to be where many interesting evolutionary events occur. Continue reading...
Could a drug that mimics a zero-carb diet help us live longer, healthier lives?
Researchers hope to develop a medication that mimics a diet stripped of carbohydrate, after two studies showed clear benefits in miceA drug that mimics a zero-carbohydrate diet could help people live longer, healthier lives and have better memories in old age, US researchers claim.Scientists hope to develop a medication after two independent studies showed that mice fed on a diet stripped of all carbohydrate lived longer and performed better on a range of physical and mental tasks than those that had regular meals.
Shock lobster: ghostly, translucent crustacean caught off Maine coast
Fisherman Alex Todd had to release the lobster as it had a notched tail, indicating it was a female potentially carrying eggs, but it was caught againIn a lobster-fishing career spanning more than 40 years, Maine resident Alex Todd thought he had seen it all. Then, last month, he hauled in a white, almost translucent crustacean which he called “by far the weirdest one I’ve caught”.Related: Consider the rare split-colored lobster: unusual catch turns up in Maine Continue reading...
Questioning evolution is neither science denial nor the preserve of creationists
New evidence suggests many who struggle to accept aspects of evolution still exhibit trust in science overall – and that even some atheists have their doubtsIn a supposedly “post-truth” era, we need to be ever mindful of threats to scientific or evidence-based ways of thinking about the world. And one of the ongoing and continual threats to a scientific worldview is “science denial”, the rejection of core accepted scientific paradigms like evolution … right?Many see the rejection of evolutionary science as a marker of religiosity or hard-line conservativism. There is a widespread assumption that religious people will find it hard to reconcile evolutionary science, and by extension science as a whole, with their religious beliefs. However, our new research turns some of this thinking on its head. Continue reading...
How can UK science raise the bar for diversity and inclusion?
A new network for equality, diversity and inclusion in research will challenge the UK scientific community to take these priorities more seriouslyLast month, the now notorious Google memo shone a depressing light on the persistence of sexism and discrimination in Silicon Valley. But these problems aren’t restricted to the tech world: a powerful new book by Angela Saini, which also surfaced over the summer, reminds us that such attitudes remain surprisingly ingrained across the wider scientific community.What can we as researchers and research funders do to change things? This week sees the launch of a new network called EDIS (Equality, Diversity and Inclusion in Science and Health Research). Co-founded by the Francis Crick Institute, Wellcome and GlaxoSmithKline, EDIS aims to inspire and encourage the UK scientific community to make equality and diversity a top priority.

How science found a way to help coma patients communicate
After suffering serious brain injuries, Scott Routley spent 12 years in a vegetative state. But his family were convinced that he was still aware – could a pioneering ‘mind-reading’ technique prove them right? By Adrian OwenOn 20 December 1999, a young man pulled away in his car from his grandfather’s house in Sarnia, Ontario, with his girlfriend in the passenger seat beside him. Scott Routley, who was 26, had studied physics at the University of Waterloo and had a promising career in robotics ahead of him. But at an intersection just a few blocks from his grandfather’s house, a police car travelling to the scene of a crime crashed into the side of Scott’s car, hitting the driver’s side full on. The police officer and Scott’s girlfriend were taken to the hospital with minor injuries. Scott wasn’t so lucky; his injuries were devastating.Scott was admitted to hospital, and within hours his score on the Glasgow coma scale – a neurological scale that measures a person’s conscious state – was rapidly dropping. The lowest score possible is three, indicating “does not open eyes”, “makes no sounds” and “makes no movements”. The highest score, 15, indicates that you are fully awake, conversing normally and obeying commands. Scott was already a four, just one step away from complete shutdown. Despite no outward signs of head or facial injury, the impact of the police car with the side of Scott’s car had slammed his brain against the inside of his skull, squeezing it into herniation and bruising it badly.

Study of Iraq fighters reveals what makes people prepared to die for a cause
In research that could help to combat extremists, scientists working on the the frontline in Iraq have begun to unpick what is behind the will to fightWhen Islamic State (Isis) launched its attack on Mosul in 2014, they were outnumbered by opposition forces by almost 40 to one – yet Isis took the city. Now a group of scientists working on the frontline in Iraq have analysed what motivates such fighters in research they say could help combat extremists.
Massive black hole discovered near heart of the Milky Way
Astronomers find evidence of enormous black hole one hundred thousand times more massive than the sun in a gas cloud near the galaxy’s centreAn enormous black hole one hundred thousand times more massive than the sun has been found hiding in a toxic gas cloud wafting around near the heart of the Milky Way.If the discovery is confirmed, the invisible behemoth will rank as the second largest black hole ever seen in the Milky Way after the supermassive black hole known as Sagittarius A* that is anchored at the very centre of the galaxy.
Office too hot? Computer playing up? Go on, have a grumble, it’s good for you | Phil Daoust
The 77 hours a year that we spend moaning at work could have advantages – for us and our colleaguesWe Brits love to moan – at least those of us who work in offices. According to the animal charity Spana, we spend up to 20 minutes a day – more than 77 hours a year – whingeing to colleagues about everything from insensitive bosses to dirty sinks, but mostly about crappy computers and horrible co-workers.“Seventy-seven hours!” you may be thinking. “That’s almost two working weeks. Imagine what you could get done in that time.” You could take up juggling, or train for a marathon. You could learn to drive and still have 10 hours left over. You could even – God help us – do more of the work you’re actually paid to do. I’m glad I’m not the complaining type. Continue reading...
When two disasters saved Earth from a worse one
Hydrogen chloride from Mount Pinatubo could have caused serious damage to the ozone layer. We were saved by a typhoonIn June 1991 the Philippine volcano, Mount Pinatubo, blew its top in spectacular fashion, producing one of the greatest volcanic eruptions in the 20th Century. It is well known that this eruption, which killed around 800 people and left 10,000 homeless, ejected so much dust into the atmosphere that it had a major effect on climate, depressing global temperatures by around 0.5°C for a couple of years. But what is less commonly known is that if Typhoon Yunya hadn’t coincided with the eruption, the impact could have been significantly worse.Related: Ozone layer hole appears to be healing, scientists say Continue reading...
Differentials for burying the war dead | Brief letters
Eton cheating | Graham Greene | First world war burials | Armageddon | Yotam Ottolenghi’s ingredientsPJ Murphy wonders if the young men of Eton and Winchester who colluded to cheat in examinations are heading for a career in banking (Letters, 1 September). If history is a guide, I suspect that they are as likely to make their way into politics, where they will find they are equally well prepared and be welcomed by familiar faces who had been taught in the same way.
Experiment reveals evidence for a previously unseen behaviour of light
Beams of light do not, generally speaking, bounce off each other like snooker balls. But at the high energies in the Large Hadron Collider at CERN they have just been observed doing exactly thatLight is useful, versatile and perplexing. We see with it - that is, we make sense of our surroundings (sometimes) using signals that our eyes send to our brains when light impinges upon them. We also use it to “see” far beyond the limits of our own sense organs. We peer deep into space, or – as at the shiny new light source just opened in Hamburg – into the complexities of atoms and molecules.Often we think of light as a wave, and that is how it often behaves. But we know that light comes in little packets – quanta – called photons. The paper which swung the scientific consensus in favour of the existence of photons was published by Albert Einstein in 1905, and yet in 1951 he wrote to an old friend Continue reading...

Want to live longer? Find your ikigai | Héctor García
In Japan, people over retirement age don’t put their feet up. They harness their ikigaiIt is now known that working for longer may help you live longer. This may not sound all that appealing, but staying in the workplace for just one year more than another retired and healthy counterpart has been shown to be associated with an 11% lower risk of death from all causes. But perhaps there’s another way to gain these extra years without commuting for any longer than necessary.The people of Japan know this intuitively, which is one of the key reasons they have the longest life expectancy in the world.

Princess Diana’s very real role in fighting the stigma of Aids | Letters
Olivia Laing, Philip Chklar, Dr Gerald Smith and Alison Hackett write in response to Hilary Mantel’s essay The princess myth. Plus letters from Vivian Cook, Edward Thomas and Chris BirchI’d like to take issue with the statements about Aids in Hilary Mantel’s otherwise wonderful Princess Diana essay (The princess myth, Review, 26 August). It is not right to say that in 1987 only the ignorant or bigoted thought that casual contact would infect them – or perhaps it’s more true to say that the ignorant and bigoted made up the majority of the population.In 1987 the US banned HIV-infected immigrants and travellers. 1987 was the year President Reagan first mentioned the disease in public, and the beginning of the UK’s “Don’t Die in Ignorance” campaign. It was also the year that the activist group Act Up was founded, meaning the very beginning of concerted public information. There wasn’t just ignorance about transmission, but widespread uncertainty in the medical community itself. As the New York Times reported in February 1987 in an article entitled Facts, theory and myth on the spread of Aids, “Experts say there is no danger in a peck on the cheek of an infected person but they recommend against any exchange of saliva and deep kissing with an infected person.” Stigma played a huge part in the ongoing nightmare of an Aids diagnosis, and whatever else one may think of Princess Diana, her gesture in touching a person with Aids did occur in a climate of widespread and unnecessary ignorance and prejudice that she did her best to dispel.
How University of Reading lent a hand in UK lentil production | Letters
News of the UK’s first lentil harvest prompts memories of university research projects from Prof Richard Ellis, and speculation about the footwear of lentil pickers from Michael CunninghamI was pleased to learn of farmers’ success with British lentil production (Finger on pulse: harvest time for UK’s lentil crops, 31 August). This augurs well for improved food chain traceability, UK food supply resilience and, of course, other advantages from legumes such as nitrogen fixation.However, I was surprised by the comment that producers were told it was impossible to grow lentils in the UK. Projects here at the University of Reading in the 1990s confirmed that while both spring- and autumn-sown lentils could be grown (and combined) successfully, the latter provided a more reliable high-quality lentil suitable for human consumption.

Europe unveils world's most powerful X-ray laser
Facility in Hamburg will help recreate conditions deep inside the sun, unravel ways to make new antibiotics and even create a new form of diamondThe world’s most powerful X-ray laser has begun operating at a facility where scientists will attempt to recreate the conditions deep inside the sun and produce film-like sequences of viruses and cells.The machine, called the European X-ray Free Electron Laser (XFEL), acts as a high-speed camera that can capture images of individual atoms in a few millionths of a billionth of a second. Unlike a conventional camera, though, everything imaged by the X-ray laser is obliterated – its beam is 100 times more intense than if all the sunlight hitting the Earth’s surface were focused onto a single thumbnail.

The Farthest review – Nasa documentary voyages to the outer limits
A witty, fascinating film about the Voyager I and II probes, launched in 1977 and now carrying their golden records beyond the solar system and into deep spaceThis exquisite, exemplary science documentary, directed by Irish editor turned helmer Emer Reynolds, recounts the rich and fascinating story of the Voyager mission, arguably Nasa’s finest, noblest contribution to scientific understanding. Launched in 1977, Voyager I and II were sent billions of miles to the outer limits of our solar system to gather information about Jupiter, Saturn, Uranus and Neptune and then into deep space. In 2012, Voyager I slipped through the heliopause and officially became the first human-made object to reach interstellar space, and it’s still going today, to infinity and beyond.Related: 40 years and counting: the team behind Voyager’s space odyssey Continue reading...

Castle of the Sealand kings: Discovering ancient Iraq’s rebel rulers
British and Iraqi archaeologists identify the first known settlement built under the enigmatic Sealand kingsThe Kings of the Sealand sound like they come straight out of a fantasy novel but it’s the name given to a royal dynasty who ruled a swathe of Bronze Age Iraq for almost three centuries (ca. 1730-1460 BCE). Archaeologists know almost nothing about the Sealand Kings or their kingdom; all we have to go on are a tiny number of ancient texts, mostly written about them by other rulers. We know they controlled the swampy land around the head of the Persian Gulf, including several of the great ancient cities of southern Babylonia, and we know that they thoroughly annoyed the Kings of Babylon from whom they’d wrestled their kingdom.
UK needs to perform thousands more obesity operations, say surgeons
NHS should offer more stomach-shrinking procedures to help people lose weight and prevent associated diseases, doctors argueThousands more stomach-shrinking operations need to be carried out in the UK, say surgeons, who warn the country is lagging behind the rest of Europe despite the toll being taken on people’s health and warnings that the obesity crisis could bankrupt the NHS.Reducing stomach size prevents people eating more than small amounts at a time, leading to dramatic weight loss. It can also reverse type 2 diabetes, which carries the risk of amputations, blindness, heart attacks and strokes. Continue reading...

Global warming doubles growth rates of Antarctic seabed's marine fauna – study
Experiment in the Bellingshuan Sea reveals temperature rise has more alarming implications for biodiversity in polar waters than previously thoughtMarine life on the Antarctic seabed is likely to be far more affected by global warming than previously thought, say scientists who have conducted the most sophisticated study to date of heating impacts in the species-rich environment.Growth rates of some fauna doubled – including colonising moss animals and undersea worms – following a 1C increase in temperature, making them more dominant, pushing out other species and reducing overall levels of biodiversity, according to the study published on Thursday in Current Biology.

Armageddon: scientists calculate how stars can nudge comets to strike Earth
Plotting how often stars stray into the Oort cloud allows astronomers to assess the risk of all life being wiped out by a cosmic cataclysmThe collision of a giant comet with the Earth is one of the most violent and cataclysmic events that could befall our planet. It has happened in the past, but the odds of another such catastrophe have remained uncertain.Now astronomers have performed the cosmic equivalent of a risk assessment. A new paper calculates how often stars stray into the Oort cloud, a vast, spherical shell of billions of icy objects that is thought to envelop our solar system. Such close encounters can dislodge these loosely orbiting comets, sending them hurtling into the solar system, risking a collision course with the Earth. Continue reading...

Why the rise of the robots could allow humans to flourish again | Giles Fraser: Loose canon
Nobody’s job is safe. But a citizen’s income in a post-work world could see us avoid the Terminator scenario and return to pre-capitalist sources of valueSemi-automated truck convoys are soon to be tested on UK roads. Perhaps, one day, human beings won’t be allowed to drive. Perhaps it will be considered too risky to put an easily distractible human being in charge of a ton or more of fast-moving metal. Future generations may think of driving as terrifyingly retro.It’s yet another example of a pressing existential question, as well as an economic one. When clever robots have taken most of our jobs, how will we live and what will we live on? For these Meccano scabs are not only going after the repetitive tasks of the long-distance lorry driver or factory workers. Once they pass the Turing test and can successfully fob themselves off as human beings, jobs that used to require a university degree will be just as much at risk. Human beings are fast heading for obsolescence. Continue reading...
