Alzheimer’s: ultrasound safely delivers drugs to damaged brains of mice
Scientists at Queensland Brain Institute find noninvasive technique slows progression of Alzheimer’s disease in miceAustralian researchers say they have made a promising step in the future treatment of Alzheimer’s disease after discovering ultrasound can effectively and safely deliver drugs to the damaged brain.Scientists at the Queensland Brain Institute found the noninvasive technique successfully penetrated the blood-brain barrier to deliver a therapeutic antibody to the brain. This then slowed the progression of Alzheimer’s disease in mice, according to a study published in the journal Brain. Continue reading...
Nasa's Cassini spacecraft to end 20-year mission by crashing into Saturn
After 22 orbits between the planet and its rings, Nasa plans for Cassini to ‘break apart, melt, vaporize and become part of the very planet it left Earth to explore’On its final mission, threading past hazardous cosmic dust and into hurricanes 1.2bn kilometers away, the Cassini spacecraft will end its 20-year journey with humanity’s closest ever look at what goes on in Saturn’s rings and within its clouds.On Tuesday, Nasa scientists unveiled their plan for the storied spacecraft, and their reasoning for driving Cassini to its own destruction: with the spacecraft running out of fuel, they do not want to risk it crashing into and contaminating Saturn’s moons, where there may be conditions for alien life.

Thousands of British children exposed to illegal levels of air pollution
Exclusive: More than 2,000 schools and nurseries close to roads with damaging levels of diesel fumes, joint investigation by Guardian and Greenpeace reveals
Don Thomas obituary
My father, Don Thomas, who has died aged 88, was inspired to take up an academic life as a biologist, by his childhood love of the rivers, mountains and wildlife of Ceredigion in Wales.Son of Dewi Jones, a farmer and poet, and his wife, Kate, Don was born at Llangeitho, a village near the market town of Tregaron, and attended Tregaron grammar school. He was always very grateful for the way that the school helped him to expand his horizons academically. By 1954 he had been awarded a BSc in zoology and a PhD from the University of Wales at Aberystwyth, where he met his future wife, Joy Robinson. They married the following year. Continue reading...
Geologists reveal how violent 'Brexit 1.0' separated Britain from Europe
Once attached to the European mainland, a new study shows how catastrophic flooding led to Britain becoming an island about 125,000 years agoBrexit might be causing political chaos but whatever Theresa May has up her sleeve it is unlikely to be as catastrophic as the first separation of Britain from the continent.A new study has revealed how giant waterfalls and, later, a megaflood severed our connection to France, resulting in the creation of island Britain and the watery moat of the English Channel.

Wanted: space volunteers willing to lie in bed for two months – for €16,000
Sleep is final frontier for French scientists studying microgravity as they seek 24 men willing to eat and perform all bodily functions in bed for 60 daysWanted: young, fit and healthy men willing to lie on their backs and do absolutely nothing for two months. Wage: €16,000.Researchers at France’s space medical institute are advertising for what could be, quite literally, a dream job. They are seeking volunteers to spend 60 days flat on their back to study the effects of microgravity, a state of virtual weightlessness. Continue reading...
Where did I put those keys? - the psychology of foraging
Psychologists have been studying visual search in the lab for decades, in order to understand how we might have developed real-world ‘foraging’ behaviour. But just how similar are the two?One of the big questions in vision research over the past 40 years has asked how we effectively search around our visual environment. Search is something that we unwittingly engage in every day of our lives – whether it’s looking for our car keys, scrabbling around for a lost contact lens, or rummaging around in a bag for a lost pen lid. But the way in which researchers have classically tested the limits of visual search have looked very different to what we might think of as search in the real world. Continue reading...
Can pre-school children learn to do science? | Jenny Rohn
Science isn’t just about explosions. But can children as young as 3 understand what it’s really about?There are few words more misunderstood than the term “science”. If you relied on the subject categories in some media outlets, you’d be forgiven for taking home the message that “science” is gadgets and technology, or pretty pictures of flowers and insects, or the latest health advice.But none of this stuff is really “science”. Science is a method for finding out how things work. In its simplest guise, a question is posed, a potential answer framed, and then an experiment designed and performed to see if the answer is right. Continue reading...
Ice age art in Indonesia reveals how spiritual life transformed en route to Australia
Cave discoveries suggest Indigenous Australians’ strong connection with animals may have its roots in the exotic species their ancestors encountered in SulawesiA cave dig in Indonesia has unearthed a unique collection of prehistoric ornaments and artworks that date back in some instances to at least 30,000 years ago. The site is thought to have been used by some of the world’s earliest cave artists.Published this week, our new findings challenge the long-held view that hunter-gatherer communities in the Pleistocene (“ice age”) of south-east Asia were culturally impoverished.

What makes people express moral outrage? | Zachary K Rothschild and Lucas A Keefer
Displays of public anger, or moral outrage, are more visible than ever. But the reasons for this are more complicated than you might thinkWhen 109 travellers entering the United States were detained by an executive order blocking citizens from seven Muslim-majority countries, tens of thousands of Americans gathered all over the country to voice their anger. The policy had little to no direct effect on the protesters themselves.Related: Britain must not change how it measures child poverty. And this is why | Kitty Stewart Continue reading...
Conservatives and liberals united only by interest in dinosaurs, study shows
Can an interest in science unite a divided society? No, concludes research based on reading habits of those from right and left of the political spectrumHopes that science and its unending quest for the truth can mend the cracks in a divided society have taken a hit as new research has found liberals and conservatives share little common ground on the subject – apart from a fascination with dinosaurs.Because science intends – in theory at least – to accrue facts from solid evidence, it stands a chance of bringing people together on issues they all agree with, such as the Earth circling the sun, and the first five digits of pi. That, the hope goes, might help reverse the social fragmentation that increasingly pits different groups against one another.
Race for Life’s branding is cliched and infantile. It’s time to sink the pink | Phoebe-Jane Boyd
Of course Cancer Research UK’s campaign is a worthy cause. But its nauseous pinkification reasserts gender stereotypes – and puts off donorsBeset upon by pink fluff on all sides, like awaking to find yourself trapped in Barbara Cartland’s musty closet, we’re once more in the midst of Race for Life fundraising season. It’s an important and worthy cause, and yet many hearts (soft, kind hearts) can’t help but sink at the pinkification. “I’ll donate later – I promise” is hesitantly mumbled to beaming participants, and donations are quietly given to the main Cancer Research UK branch instead.Related: An open letter to readers from the Colour Pink | Eva Wiseman Continue reading...

The first shovelful: introducing our new archaeology and anthropology blog
Meet the experts behind the Past and the Curious, who will be digging deep to bring Guardian readers the inside scoop on archaeology and anthropologyHere we go, a new archaeology and anthropology blog, bringing you tombs, treasures, tribes and high adventure. Well maybe; we’re hoping there’ll be even more interesting and unexpected things than those to be honest. There’s plenty more going on than the stuff that usually makes the papers and together the five of us will aim to bring you a view from the inside on some of the most important discoveries and ideas that are shaping archaeological and anthropological research right now; the things that the experts are excited about. We’ll take you on a tour of some of the most fascinating excavations, past, present and future. We’ll reveal the studies being done with contemporary communities around the world, and the secrets being revealed by evolutionary and forensic anthropologists.What unites archaeology and anthropology is that they are about people – past and present - based on the complex, multi-layered evidence available. We are interested in everything. No other research areas approach the study of humanity in such varied and encompassing ways. Continue reading...
Bloodthirsty chomp-monster or sensitive lover? Time to rethink Tyrannosaurus rex | Brian Switek
No other dinosaur has sunk its teeth so deeply into our imagination, yet the focus on its hunting means we’re surprised to discover it was a real, living animalWe’re over 66 million years too late to know what tyrannosaurus mating rituals entailed. Whether the immense carnivores courted like oversized albatrosses, offered gifts of semi-rotted triceratops meat, or simply got down to business without pretence is a vignette lost to Cretaceous time. But research published last week in the journal Scientific Reports has spurred headlines suggesting that the great and powerful T. rex might have been a sensitive lover.The new study – perhaps to the chagrin of the authors – was not specifically about T. rex itself. Carthage College palaeontologist Thomas Carr and colleagues described a new species of tyrannosaur, Daspletosaurus horneri, excavated from the 75m-year-old rock of Montana. The specimen that forms the core of the description is gorgeous, with dark grey bones preserved in exquisite detail, and that palaeontological happenstance is what has set off the hubbub over tyrannosaur foreplay.

Israel's medical marijuana pioneers look to cash in on $20bn market
Country has seen 500 companies apply to join ‘green rush’ in cannabis products after more than 100 studies in pharmaceutical useIn a small pharmaceutical lab in Jerusalem, a complex construction of rubber tubes, pumps and a brass pipe sits on a worktop. A prototype device, its purpose is to “smoke” cannabis to remove its active constituents and turn them into powder, with the hope that the resulting product can be used for pain relief in young cancer patients.The Izun lab offers a glimpse of the ambition by Israeli researchers to corner the rapidly burgeoning new global market in medical marijuana, a market its proponents argue soon could be worth almost $20bn (£16bn) annually by 2020 in the US alone.

Medieval villagers mutilated the dead to stop them rising, study finds
Archaeological research may represent first scientific evidence of English practices attempting to protect the living from the deadA study by archaeologists has revealed certain people in medieval Yorkshire were so afraid of the dead they chopped, smashed and burned their skeletons to make sure they stayed in their graves.The research published by Historic England and the University of Southampton may represent the first scientific evidence in England of attempts to prevent the dead from walking and harming the living – still common in folklore in many parts of the world.

Dust to dust, boulders to boulders
An experiment shows how particles of varying sizes sort themselves out on the surface of a small asteroidBack in 2005 a small asteroid, known as 25143 Itokawa, was visited by the unmanned Japanese spacecraft, Hayabusa. Close up images of the asteroid – which measures approximately 540m by 250m – revealed that the “lowlands” were covered by dust and centimetre-sized small pebbles, whilst the “highlands” were made up from larger boulders (5 to 40m diameter). But how did this segregation come about?Initially researchers thought that the size sorting on Itokawa was most likely due to the Brazil Nut Effect, whereby smaller particles rattle downwards when something is shaken. But the force of gravity is weak on Itokawa, meaning that the Brazil Nut Effect would be unlikely to create such extreme sorting. Instead Troy Shinbrot, from Rutgers University in New Jersey, USA, and his colleagues suggest that for the high-speed particles that bombard the asteroid, pebbly regions are “stickier” than boulder fields.

Charles Darwin a racist? Look at his involvement in the Jamaica Committee | Letters
“Most early evolutionists were racist, Darwin included,” claims your correspondent (Letters, 30 March). Mid-Victorian intellectuals can conveniently be identified as racist or anti-racist by their reactions to the 1865 Morant Bay rebellion in Jamaica and the brutal reprisals of Governor John Eyre.Darwin was a leading light of the Jamaica Committee, which tried to have Eyre prosecuted, and recruited most of the leading scientists of the day. The racists organised an Eyre defence committee, led by Thomas Carlyle, Charles Dickens and John Ruskin. Continue reading...
Why the sound of Ed Sheeran helps sell fries
Swedish researchers have found that specially selected songs played in a fast-food chain increased takingsIt’s elevator music, 21st-century style: not Herb Alpert, piped tinnily into your local department store, but carefully curated playlists generated by algorithms and used by major restaurants, supermarkets and retailers all over the world to entice us to spend more cash. In the largest study of its kind, researchers from the Swedish Retail Institute – in collaboration with Spotify-backed startup Soundtrack Your Brand – found that specially selected songs increased customers’ spending by 9.1%.Conducted at an unnamed American burger chain in Sweden, and analysing almost 2m purchases, the research compared the difference in sales when playing music chosen to match the brand with randomly selected popular songs. When playing bespoke playlists, sales of burgers went up by 8.6%, fries by 8.8% and desserts by a whopping 15.6%. The underlying message: if we like a tune, we’ll buy more chips. Continue reading...
HSBC should forget Mr, Mrs and Mystery. Here’s the only title we need | David Shariatmadari

At least, that’s what HSBC thinks. It may no longer be “the listening bank”, but it’s listened to its customers in all their gender diversity, and provided them with 10 new titles to choose from on official forms. These include “Ind” for individual, “Mre” for mystery, “Pr” for person and “Misc” for miscellaneous.Related: ‘Dear Sirs’ goes gender neutral Continue reading...
Is fasting a free health fix – or is it just a fad?
Restricting the amount you eat is said to fight disease, extend lifespan and improve wellbeing. As well as dieters, people with diabetes and MS could benefitYou probably first came across it with a pale-looking colleague slumped over their office desk. Or with The Fast Diet author Michael Mosely speaking effusively about it on television. Fasting, they’d have told you, is a great way to lose weight. It makes sense: eat fewer calories a couple of days a week, and don’t overeat on the others, and you’ll slim down. What’s less clear is the assumption that fasting from time to time can bring other benefits such as avoiding disease, keeping your brain sharp and even letting you live longer. With all this for the price of just a sprinkle of willpower though, surely it’s all too good to be true?The answer is not straightforward. Perhaps unsurprisingly, the evidence is strongest with type 2 diabetes – a disease often caused by overeating. The disease means that a person can no longer control their blood sugar levels. Once diagnosed they are left staring down the barrel of a lifetime on medication, unless, think researchers at Newcastle University, they begin to fast. Continue reading...

Sydney Observatory: the dome that brings the stars to Australians
A site once used to guide ships and tell the time focused its attention on the skies in the latter part of the 19th century – and hasn’t looked backWhen Australia’s first government astronomer, William Scott, took up his posting in 1858 in Sydney, his equipment was so defective that, according to his diary records, it “destroyed all confidence in the result furnished by it”. And the shutters that were supposed to protect the finely calibrated instruments within the dome let in “a considerable quantity of rain” when the wind was high.It was an uneasy start to an important mission. But Scott would probably be pleased to learn that the observatory he built in Sydney still stands. And more than 150 years later the dome that looks over the city is continuing to fulfil the role Scott envisioned of opening the stars to all Australians. Continue reading...
Outrage makes you feel good, but doesn’t change minds | Sonia Sodha
The left must learn that moral outrage will never win an argumentIt took but a quick click, but even as I joined the collective expression of disgust on social media at last week’s Daily Mail “Legs-it” front page I felt a bit sheepish. Not because juxtaposing a headline that posed the question of who had better legs next to a photo of Theresa May and Nicola Sturgeon wasn’t deeply sexist, but because it was a futile gesture, and I knew it.We lefties have impeccable pedigree when it comes to righteous outrage. It has a time and a place: there’s something life-affirming and motivating about asserting your membership of a tribe with common values. But it also carries something of the guilty pleasure: the smug satisfaction of earning your virtue-signalling stripes in our social media age. Continue reading...

This is it: the one true explanation for Donald Trump's victory
Everyone’s theories are wrong: through cunning and selective use of statistics, I can prove that my pet whinge is the reason for Trump’s election winThe unexpected US election result has left people grappling with some difficult questions. Questions like, “if we’re so good at being pundits then why were we all wrong?” and, “how do I draft an executive order without cocking it up?” One question stands above all others though: “Why did millions of people who nearly always vote Republican continue to vote for a Republican candidate, even after lots of Democrats and centrists told them not to?”To find out, we have to use the key tool of analysis available to political science in the Internet era: the think piece. Think pieces are the social media equivalent of an immune response, an innate and primitive defense system in which endless varieties of the same basic cell swarm over a topic until it’s entirely obscured by a cloud of literary pus.

Can you dig it? Badger captured on camera burying cow

Can you prevent rows about household tasks?
Even among couples who share housework and parenting, subtler inequities persistIn her new book Drop The Ball, a manifesto for women juggling jobs and an unequal share of the burden at home, Tiffany Dufu describes a phenomenon I’d never previously seen given a name: “imaginary delegation”. This is the all-too-familiar relationship pattern whereby you see (or just think of) some household task that needs doing, mentally assign it to your partner, fail to inform them you’ve done so, then feel sincere outrage when they disregard the instructions you never gave them.The problem here is that both sides have an excellent case for feeling aggrieved. The person on the (non-)receiving end naturally protests that he can’t be expected to read minds. But the other person is also justified in saying she shouldn’t need to spell it out: for a cohabiting couple, teamwork demands that both partners keep an eye out for what needs doing, without being told by the other. So the stage is set for the worst variety of domestic row: the kind where both parties are right. Continue reading...

Lab notes: baby, love me like a T rex
Well, big in all sense of the word is the news that the discovery of a new member of the tyrannosaur family has revealed that these fearsome dinosaurs had sensitive snouts that they may have enjoyed rubbing together while mating. It’s a sweet mental picture, no? Anyway, canoodling carnivores aside, there have been some really exciting breakthroughs this week, including the amazing neuroprosthetic work featured in this week’s video section below. One study that could have an enormous impact on worlds health is the discovery that the short-chain fatty acids produced by a diet rich in a certain type of fibre could prevent type 1 diabetes. We await human trials with hope and interest. Less vital, but no less interesting is the news that lonely people feel more rotten when they get a cold – but aren’t actually any more ill than their less lonely counterparts. Warning: there’s some mucus talk in the piece, so finish your sandwich before reading, eh? Finally, it seems that fruit foraging rather than social interaction may be key to the evolution of large brains in primates. Continue reading...

Ken Harrap obituary
Cancer researcher whose work on drug development had a major impact on life expectancyKen Harrap, who has died aged 85, was a pioneer in the development of anti-cancer drugs. The research he directed over several decades in the UK resulted in the discovery of three registered cancer drugs, carboplatin, raltitrexed and abiraterone, an outstanding achievement.When Ken was born there were no effective anti-cancer drugs and, except for patients in the early stage of the disease who could be cured by surgery, a diagnosis of cancer was a death sentence. Today, thanks to treatment in which his drugs play an important role, more than half of cancer patients can expect to be alive 10 years after diagnosis. Continue reading...
Teach evolution – but not in a moral vacuum | Letters
Jules Howard writes that teaching evolution from an early age would help combat racism and promote humanist values (Utopian thinking: Forget British Values – teach children they are apes, theguardian.com, 27 March), but this is not borne out by experience. Most early evolutionists were racist, Darwin included. Some of the most brilliant evolutionary theorists, such as Francis Galton and Ronald Fisher, were strong proponents of eugenics. That this strand of thinking is mostly abandoned in today’s mainstream evolutionary biology is reassuring, but does not stem from any particular scientific finding. Rather, it was the horrors of Nazism (itself strongly influenced by evolutionary ideas) that made further promotion of racism and eugenics untenable.Another optimistic expectation is that the realisation that we are apes would free us of our bodily embarrassment. Again, this is not supported by evidence. The contrary seems to be the case, where anxiety about their position in the mating market stemming from their understanding of evolutionary theory leads many men to extremely misogynistic thinking. This can be seen in the flourishing of the online “red pill” trolling culture. Continue reading...
