How a tax haven is leading the race to privatise space
Luxembourg has shown how far a tiny country can go by serving the needs of global capitalism. Now it has set its sights on outer spaceOn a drizzly afternoon in April, Prince Guillaume, the hereditary grand duke of Luxembourg, and his wife, Princess Stéphanie, sailed through the front doors of an office building in the outskirts of Seattle and into the headquarters of an asteroid-mining startup called Planetary Resources, which plans to “expand the economy into space”.The company’s engineers greeted the royals with hors d’oeuvres, craft beer and bottles upon bottles of Columbia Valley rieslings and syrahs. In the corner of the lounge stood a vintage Asteroids arcade game; on the wall hung an American flag alongside the grand duchy’s own red, white and blue stripes. Between the two flags was a prototype of a spacecraft designed to roam the galaxy, prospecting asteroids for precious natural resources that would someday – at least in theory – make the shareholders of Planetary Resources very wealthy earthlings indeed.

Solid and liquid cats, didgeridoos and cheese disgust scoop Ig Nobel awards
Scientists from around the globe gathered for annual ceremony celebrating research that ‘first makes you laugh, then makes you think’In ancient times, cats were worshipped as gods. Now a scientific paper arguing that the feline species may indeed transcend some of the usual physical boundaries has been recognised with one of science’s most sought-after accolades: an Ig Nobel prize.The theoretical treatise, entitled On the Rheology of Cats, argues that cats can technically be regarded as simultaneously solid and liquid due to their uncanny ability to adopt the shape of their container.

New technology could allow multiple vaccines to be delivered in single jab
A new technique allowing drugs or vaccines to be encapsulated within tiny biodegradable particles could see an end booster jabsMultiple injections for vaccinations could become a thing of the past, according to scientists who have developed an approach for delivering many doses of different substances in just one jab.The technology involves encapsulating drugs or vaccines within tiny particles made of biodegradable polymers. Depending on their makeup, these polymers break down at different points in time, releasing their contents into the body. Continue reading...

Have you been affected by the misuse of Pregabalin in the UK?
The misuse of Pregabalin, a drug used to treat anxiety and epilepsy has been linked to a rise in the number of deaths. Share your experiencesA growing number of deaths have been linked to the misuse of Pregabalin, a drug used to treat pain, anxiety and epilepsy. In 2012 there were four deaths linked to it and last year this rose to a 111.It comes after claims that the drug has flooded the black market and is being sold illegally to addicts who mix it with other drugs, such as heroin. This can increase the risk of heart failure. Continue reading...
Nasa's Cassini spacecraft poised to begin mission-ending dive into Saturn
On Friday, the spacecraft will plunge toward the giant planet and burn up in its atmosphere, ending a remarkable 20-year journey over eight billion kilometresAfter one last look at Saturn and its moons, Nasa’s Cassini spacecraft will call time on its 20-year mission on Friday when it dives headlong into the giant planet and burns up in the atmosphere.And so a man-made meteor will streak across Saturn’s sky soon after 11.30 am UK time, though confirmation of the spacecraft’s demise more than a billion kilometres away, and on the wrong side of the asteroid belt, will not reach Earth for another 83 minutes, when the signals beamed home from the probe fall silent.

Diving for Dakuwaqa: giving Fiji's shark god a helping hand
Dakuwaqa reputedly protects those at sea. But with almost 70% Fiji’s shark species threatened with extinction, it’s time for humans to return the favourThe Fijian shark culture and mythology is one which deeply appeals to me. The shark is revered by many Fijians, and legend has it that Dakuwaqa, the ancient shark god, provides protection for the people when at sea.But the tables are turned, and Dakuwaqa now urgently needs the help of his people: almost 70% of the 75 recorded elasmobranch species inhabiting Fijian waters are considered to be globally threatened with extinction.

It's an alpha male thing: what dominant chimpanzees and Donald Trump have in common
When it comes to US presidents, we expect to see a combination of prestige and dominance. Donald Trump’s Twitter tirades and demands for fealty show he prefers the latter – an ape-like strategy for successFrom early 1974 through most of 1976, a male chimpanzee named Yeroen held the position of alpha leader in the large, open-air chimpanzee colony at Burgers zoo in Arnhem in the Netherlands. His reign was roughly coterminous with the presidential administration of Gerald R Ford in the United States.Yeroen became famous (among Homo sapiens) when the Dutch primatologist Frans de Waal showcased his leadership style in a classic 1982 book, Chimpanzee Politics. In their Machiavellian machinations and power games, De Waal argued, chimps turn out to be a lot like human beings. Continue reading...
Statistical vigilantes: the war on scientific fraud – Science Weekly podcast
Hannah Devlin delves into the case of a shamed Japanese scientist to explore how statistical malpractice is damaging science - whether employed knowingly or notSubscribe & Review on iTunes, Soundcloud, Audioboom, Mixcloud & Acast, and join the discussion on Facebook and TwitterOn paper, the Japanese anaesthesiologist Yoshitaka Fujii was a dazzling model of scientific productivity. Over two decades, he held posts at five institutions, associate positions at two more, and published more than 200 papers. In some years, he published a dozen randomised control trials – and it was this superhuman publication record that started to arouse suspicion among some of his colleagues. But it was only when a British doctor began scouring through the statistics in his papers that the phenomenal scale of Fujii’s scientific fraud became clear. Continue reading...
Exodus begins as swifts muster for migration
Sandy, Bedfordshire A leave-taking of Britain is playing out in the skies as swifts and martins fuel up for their epic journeyThrough these last weeks of summer, the autumn migration has played out in the skies, though it goes largely unnoticed by most below. A trickle of an exodus began over the bank holiday with three dark specks, way, way up in the blue. Specks, yes, but you could see, from the wings curved like taut bows, that they were unmistakably swifts.Hatched on northern ledges they had become citizens of heaven. They deviated on insect-chasing sallies in all directions, but were overall tracking south-west. Continue reading...
Artificial sweeteners raise risk of type 2 diabetes, study suggests

James Dyson says tuition fees hit students with debt at 'worst time'
Inventor was speaking at opening of his technology institute, where his firm will pay students £15,000 a year and their feesSir James Dyson has said tuition fees and student loans are saddling young people with huge debts at the “worst time” in their careers, holding them back from earning valuable qualifications.Speaking ahead of the formal opening of his own institute of technology, which does not charge tuition fees, the designer and industrialist said the scale of loans and fees at English universities was increasingly likely to deter young people from studying at university.

How a newly-discovered mastodon jaw became a mammoth mystery
Dr Chris Widga and his team thought the remains they were excavating were ‘just another mastodon’. But when the jaw appeared, it was unlike anything the team had ever seen. What exactly could it be?He’d been offering tantalising hints throughout his presentation: an ulna here; a large femur there; a calculated weight of 16 tons for this animal. But it wasn’t until he showed an image of the excavated jaw that some of us became really excited.This wasn’t a typical mastodon.
Stone stackers at ancient sites could face jail, warns Historic England

With its lack of diversity, the Science and Technology Committee scores an own goal
It is a disgrace that the latest iteration of a key Commons group is composed entirely of menAsk a group of people to nominate candidates for an important role and the chances are they’ll come up with a bunch of men. The evidence shows this time and time again. Think of the much-mocked Northern Powerhouse event earlier this year, with its dearth of female speakers, or the all-male panel – now colloquially known as a manel – which too many conferences showcase.Many men are sufficiently annoyed by this to sign up to pledges, refusing to talk on platforms in which there is insufficient gender diversity. This is progress, but it’s depressingly slow. In STEM fields the problem is probably more acute than in, say, humanities. We are long way from seeing a transformation in scientific leadership despite the numbers of women rising through the hierarchy growing steadily. Continue reading...
Overdoses on opioid painkillers more than double in a decade
Number of hospital admissions in England rose to 11,660 last year as doctors say drugs are being prescribed too readilyThe number of patients admitted to hospital for overdosing on powerful and potentially addictive opioid painkillers has more than doubled in a decade, with doctors saying it is the “very worrying” consequence of the drugs being prescribed too readily.
E-cigarette science – is scaremongering hampering research opportunities?
We need more trials into the long-term impacts of e-cigarettes, but is disagreement between scientists over their effects putting people off taking part?Whenever I tell anyone I research e-cigarettes, they almost always have an opinion about them. Some will be vapers themselves, and those who are will almost without fail sing the praises of the device that finally helped them quit smoking. But often people who’ve never tried e-cigarettes will focus on the potential risks from using them, and in particular whether they’re likely to reintroduce smoking to a young generation who have been steadily shunning it in larger and larger numbers over recent decades. A particular fear is that young people will experiment with e-cigarettes and that this will be a gateway in to smoking, as well as fears around the harms from e-cigarettes themselves.Related: Fears over e-cigarettes leading to smoking for young people unfounded – study Continue reading...
Life in the old bird yet: study of dodo bones yields new biological insights
It’s easy to think that dusty old bones have nothing left to offer, but a new study of dodo bones has given us a glimpse into a long-dead world“So rapid and complete was their extinction, that the vague descriptions given of them by early travelers were long regarded as fabulous or exaggerated, and these birds, almost contemporaries of our great-grandfathers, became associated in the minds of many persons with the Griffin and the Phoenix of mythological antiquity.”Hugh Strickland, 1848, in Strickland & Melville’s The dodo and its kindred.

Horizon: Mars – A Traveller’s Guide review – a nice change from water parks and bar crawls
It’s a dream trip if you like geology – all rocks, craters and volcanoes. Plus, The 100 Year Old Driving SchoolWe holidayed in Cornwall and France again this year, as we do every year. And I’m thinking next year we might do something different. Been looking into options, from Ibiza to the Norfolk Broads. Or maybe Mars, in which case this Horizon: Mars – A Traveller’s Guide (BBC2) will be useful. It won’t be long before it happens; many scientists think the first person to set foot on the red planet is alive today.The programme is handily divided into sections: getting there, what to do and see etc. With experts. Spacecraft structures engineer Abbie Hutty explains the journey. Not entirely surprisingly it isn’t easy, rocket science. The landing especially, with temperatures of 1750C generated as you enter Mars’s atmosphere. Don’t forget your heat shield. Then there are the ferocious winds and the dust. Oh, and the journey takes seven months. Bloody hell, we find the seven-hour drive to Cornwall a challenge, seven months is going to be a nightmare. I spy with my little eye something beginning with “S”… Star? ... Yup. Continue reading...
The Coalition attacks environmental groups with advice straight from the mining lobby | Tim Flannery
The lobby’s recommendations for environmental charities would set a dangerous precedent and could hamper any community group the government deems to be in conflict with its worldviewTens of millions of dollars are spent annually on political lobbying for the interests of the fossil fuel sector. That investment serves the interests of a small amount of company shareholders in keeping a legacy industry alive, despite the availability of newer, clean technologies, at lower cost.In the wake of these behind-the-scenes policy negotiations, the real and present impacts of climate change, such as bushfires, coastal flooding and reduced crop yields are left at the door of future generations to deal with.

Real face of mummified warrior revealed at British Museum
Scythian man’s head goes on display along with scan showing his features, including moustache, pierced ear and long scarThe real face concealed by a clay mask on the mummified head of a Scythian warrior has been revealed for the first time in almost 2,000 years. The head is on display in an exhibition opening at the British Museum this week along with the scan, made in a St Petersburg hospital, which reveals that he had fine teeth, a ginger moustache, a pierced ear, a hole in his skull where his brains had been removed, and a savage wound, beautifully stitched and healed, which originally ran from the corner of his eye socket to the point of his jaw.Since the real head closely resembles the painted mask, the curator St John Simpson assumes that the faintly smiling mask of a young woman beside him, which has yet to be scanned, is also based on her appearance in life.

Little evidence that light drinking in pregnancy is harmful, say experts
Women worried by guidance advising abstinence should be told there is little evidence that the odd glass of wine causes harm to the baby, says studyMothers who are consumed by anxiety and guilt for having drunk the odd glass of wine when they are pregnant should be reassured by a new study showing there is very little evidence that it harms the baby, say experts.Drinking in pregnancy is a fraught issue and causes much anxiety. Last year new guidance to the NHS in England urged women to try not to drink at all, but in the real world, say the new study’s authors, up to 80% in the UK, Ireland, New Zealand and Australia drink some alcohol while they are pregnant. Since half of all pregnancies are unplanned, many women drink before the test shows positive. Continue reading...

The Guardian view on exploring Saturn: an inspiring distraction | Editorial
The great success of the Cassini mission deserves our appreciation, but Nasa’s work on Earth’s climate matters moreThe Cassini mission, which will end on Friday, is one of the most wonderful achievements of the human race. A slack-jawed awe is the only proper reaction to the spacecraft’s travels and to its intricate route over seven years to Saturn, aided by the slingshot effects of its grazing the orbits of the inner planets, first Venus and then Earth, as it passed them in vast loops, representing astonishing feats of calculation.Nor was it enough just to reach the outer planets and their region of immense distances from the Sun, from us and from each other. The flypasts of Jupiter and its moons, reached after three years, and then the orbit of Saturn attained four years later, are wonders of remote control and communication. The pictures that Cassini has sent back of the surface of the moons it has explored – and it actually landed the smaller probe, Huygens, on one of them – enlarge our vision of the universe as nothing else could.

Ross Lazar obituary
My friend, work colleague and cousin by marriage, Ross Lazar, who has died aged 72 of cancer, was a psychotherapist and organisational consultant who spread British psychoanalytic ideas across Europe. A central part of his career lay in psychoanalytic psychotherapy and its associated observational studies. But in parallel he also developed a second strand working with groups and organisations.Born to Jack, a businessman, and Pearl (nee Wachs), a legal secretary, in New Jersey, Ross came to Britain in the early 1970s to train at the Tavistock Clinic in London, where the Kleinian school of psychoanalysis – grounded in the observation of infants, children and families – had been established.

Huge increase in badger culling will see up to 33,500 animals shot
Ministers say culls are vital for cutting TB infections in cattle but scientists say there is little evidence to support the policyUp to 33,500 badgers will be shot this autumn in an attempt to control tuberculosis in cattle, a huge rise from the 10,000 killed in 2016.The government has announced that 11 new badger cull areas have been licensed, adding to the 10 already in place. Devon now has six badger culls under way, with Somerset and Wiltshire having three each, with others in Cheshire, Cornwall, Dorset, Gloucestershire and Herefordshire. Continue reading...

Want to be happier? First, work out if you’re an ‘upholder’ or a ‘rebel’
Happiness expert Gretchen Rubin says there are four basic personality types, and improving your life is all about working out whether you conform or rise upIn the often-woolly world of personal development, Gretchen Rubin is a practical and grounded sort. She doesn’t even – shock – like meditation. Rubin has spent the past decade researching and writing about happiness. A former lawyer, it was her fifth book, The Happiness Project written in 2009 – for which she spent a year testing different theories about how to live a more fulfilled life – that became a bestseller and made her a star of the self-help world (she also runs a popular blog and podcast).Her latest book, The Four Tendencies, develops ideas first explored in 2015’s Better Than Before, in which she looked at how happiness and habits were linked. “[People] wanted to run,” she says, “but for some reason they couldn’t make themselves exercise. Or they wanted to write a novel in their free time, but somehow they weren’t doing it. It was trying to figure out why people did and didn’t break habits.” Continue reading...
Stop talking right now about the threat of climate change. It’s here; it’s happening | Bill McKibben
Hurricane Harvey, Hurricane Irma, flash fires, droughts: all of them tell us one thing – we need to stand up to the fossil fuel industry and fastFor the sake of keeping things manageable, let’s confine the discussion to a single continent and a single week: North America over the last seven days.In Houston they got down to the hard and unromantic work of recovery from what economists announced was probably the most expensive storm in US history, and which weather analysts confirmed was certainly the greatest rainfall event ever measured in the country – across much of its spread it was a once-in-25,000-years storm, meaning 12 times past the birth of Christ; in isolated spots it was a once-in-500,000-years storm, which means back when we lived in trees. Meanwhile, San Francisco not only beat its all-time high temperature record, it crushed it by 3F, which should be pretty much statistically impossible in a place with 150 years (that’s 55,000 days) of record-keeping.

Our native grass snake has been promoted but remains elusive
Little Bradley Ponds, South Devon Taxonomy tussles aside, spotting any grass snake can be far from easy, and I circled the ponds several timesThis small nature reserve was my final stop: a tranquil oasis surrounded by woodland and set back from the road near Bovey Tracey in south Devon. I had spent the morning visiting gardens in search of grass snakes, nosing around compost heaps and scanning the edges of ponds without luck. Reptiles known to inhabit one glorious wildlife-friendly property on the edge of Buckfastleigh had kept out of sight, while nearby locations offered up handsome slow worms, but not the secretive species I was after.

Hostage to myopic self-interest: climate science is watered down under political scrutiny | Ian Dunlop
Scientific reticence allows politicians to neglect the real dangers we face. But waiting for perfect information means it will be too late to actThree decades ago when serious debate on human-induced climate change began globally, a great deal of statesmanship was on display. A preparedness to recognise that this was an issue which transcended nation states, ideologies and political parties. An issue which had to be addressed proactively in the long-term interests of humanity, even if the existential nature of climate risk was far less clear cut than it is today.Then, as global institutions were put in place to take up this challenge and the extent of change this would impose on the fossil-fuel dominated world became more obvious, the forces of resistance mobilised. Today, despite the diplomatic triumph of the Paris climate agreement, debate around climate change policy has never been more dysfunctional, indeed Orwellian, particularly in Australia.

Ancient Egyptian treasures uncovered in tomb near Valley of the Kings
Mummies, jewels and sarcophagi are among the 3,500-year-old treasures discovered in a goldsmith’s tomb in necropolisA remarkable ancient Egyptian tomb has been discovered in the necropolis of Draa el-Naga, near Egypt’s famous Valley of the Kings.The tomb consists of a small room at ground level and a burial chamber eight metres below containing four mummies. Its principal occupant was a goldsmith named Amenemhat from the 18th Dynasty (1550BC to 1292BC), the time of Tutankhamun, Nefertiti and Hatshepsut. The tomb also contains skeletons, funerary artefacts, including 150 ushabti statues, intended to be servants in the afterlife, and four wooden sarcophagi, jewellery and funerary cones.

Lab notes: there's a hole (near) my heart that can only be filled by ... this week's science!
The most exciting story this week is kind of about nothing ... but a very big nothing. Astronomers have found evidence of enormous black hole one hundred thousand times more massive than the sun hiding in a gas cloud near the galaxy’s centre. It’s not just a big hole though: it could help us understand how supermassive black holes form. And while we’re still gazing heavenward, everyone’s favourite dwarf planet, Pluto, has had its surface features officially named. Pluto’s mountains, craters and regions now celebrate global mythology, explorers, map-makers and a British schoolgirl, among others. Feeling sleepy after all that stargazing? If so, you’re lucky: researchers have revealed that insomnia could contribute to mental health problems. On the up side, the study showed that therapy designed to treat insomnia also reduced paranoia and hallucinations, and improved depression and anxiety in patients. More positive news on the health-improvement front: it seems that a pacemaker-liked device that “hacks” the body’s neural circuits could alleviate symptoms of diseases from rheumatoid arthritis to Crohn’s. The scientists responsible say it could be the end of pills for certain illnesses – an extraordinary boon for anyone living with chronic disease. Excellent news indeed, because scientists are hoping to develop a medication that mimics a diet stripped of carbohydrate, after two studies showed that mice on a zero-carb diet lived longer and and performed better on a range of physical and mental tasks than those on a regular diet. More time for contemplating the heavens, then. Continue reading...
Watch out for the northern lights tonight – UK could be in for a big display
Those in the UK should look northwards for the aurora tonight as the aftermath of the biggest solar flare for more than a decade continues to pummel EarthThe particle ‘debris’ created by a monstrously large solar flare reached Earth at around 00:00 BST last night. It sparked displays of the northern lights that were seen as far south as Edinburgh in Scotland and Arkansas in the US.At 00:12 BST, Lancaster University’s Aurorawatch issued an amber alert, meaning that aurora is likely across Scotland, northern England and Northern Ireland. A dozen minutes later, they upgraded to red alert, saying “It is likely that aurora will be visible by eye and camera from anywhere in the UK.” Continue reading...
Could electrical implants replace pills for some illnesses?
A pacemaker-liked device that ‘hacks’ the body’s neural circuits could alleviate symptoms of diseases from rheumatoid arthritis to Crohn’s, say researchersA pioneering approach to tackling a host of diseases using an electrical implant could eventually reduce or even end pill-taking for some patients, researchers have claimed.The technology relies on electrical stimulation of the vagus nerve – a bundle of nerve fibres that runs from the brain to the abdomen, branching off to organs including the heart, spleen, lungs and gut, and which relays signals from the body’s organs to the brain and vice versa.

Parasites are nature’s great givers. Protecting them must be on our tick-list | Jules Howard
They may cause misery, pain and zombie cockroaches, but parasites are also responsible for glorious biodiversity. Now climate change threatens their survivalHave you ever seen a headless toad? If the answer is no, now is a good time to go out looking for one. You see, it is almost exactly at this time of year that they are becoming headless thanks to the actions of tiny parasites that are emerging from out of their bodies. It is with these creatures that I would like to begin this piece about the worthiness or worthlessness of parasites.Related: Climate change could wipe out a third of parasite species, study finds Continue reading...

Pluto: dwarf planet's surface features given first official names
Mythological figures, astronomers, explorers and a British schoolgirl are among those immortalised as mountains, craters and regions on the distant worldA British schoolgirl who came up with the name “Pluto” for a newly-found planet in 1930 has been immortalised on the distant world by having a crater named after her.On hearing of the planet’s discovery from press reports, 11-year-old Venetia Burney from Oxford proposed the name of the Roman god of the underworld to her grandfather, a librarian at the city’s Bodleian library. He dutifully passed it on to US astronomers where it was approved by Clyde Tombaugh, who had spotted the rocky body.
