Solanezumab blocks memory loss in patients with mild version of the disease, making it the first medicine ever to slow pace of damage to patients’ brainsScientists appear to have broken a decades-long deadlock in the battle against Alzheimer’s disease after announcing trial results for the first drug that appears to slow the pace of mental decline.The drug, called solanezumab, was shown to stave off memory loss in patients with mild Alzheimer’s over the course of several years. The effects would have been barely discernible to patients or their families, scientists said, and it is no cure. But the wider implications of the results have been hailed as “hugely significant” because it is the first time any medicine has slowed the rate at which the disease damages the brain.

Promising results of studies into use of solanezumab expected to be announced at Alzheimer’s conference in Washington

Ray Flynn, a partially sighted pensioner, has his central vision restored after receiving a bionic eye. The 80-year-old, from Audenshaw, Manchester, is the world's first patient with advanced dry age-related macular degeneration (AMD) to undergo the procedure. Flynn hopes the retinal implant will restore his quality of life Continue reading...

A music festival might not seem an obvious place to see and hear science, but Latitude was full of it.Why do people go to music festivals? When I was 18 years old and heading to Reading festival the answer was very much ‘to listen to Pulp and Beck in a field while drinking overpriced beer and definitely not trying to sneak a hip flask on to the site’. But I’ve grown up since then, and so, it seems, have festivals.At Latitude this weekend, I probably only watched a handful of bands. Not to say that the musical lineup wasn’t great, but there was so much more on offer that caught my attention. The Wellcome Trust funded a large number of talks, interactive sessions and demos that appeared both in their ‘hub’, a tiny tent on the outskirts of the festival, but also in the Literary Tent at the heart of the festival and at other locations across the site.

Study also reveals some groups in South America have closer genetic ties to indigenous peoples of Australia, New Guinea and the Andaman Islands than to present-day Native AmericansNative American ancestors reached the new world in a single, initial migration from Siberia at most 23,000 years ago, only later differentiating into today’s distinct groups, DNA research revealed Tuesday.

The vanity bus commissioned by London mayor Boris Johnson has more than electrical problems (Boris buses ‘running on diesel’ due to battery fault, 20 July). This new bus was designed with no windows that open and no air conditioning. This means that on warm days they become ovens, especially on sunny days. One of these days someone will pass out from the heat on the bus and someone might even die. I had to get off one the other day to avoid collapsing from the intense heat.

Study finds that form of therapy which uses electric current blunted activity in rats’ hormonal pathway linked to stress, chronic pain and moodA biological mechanism explaining part of the mystery of acupuncture has been pinpointed by scientists studying rats.Stimulation with electroacupuncture – a form of the therapy in which a small electric current is passed between a pair of needles – blunted activity in a key hormonal pathway linked to stress, chronic pain and mood, the researchers found.

Researchers find transistors can be produced consisting of atoms 600,000 times thinner than a human hair – paving way for atom-scale chipsScientists have created a transistor made up of a single molecule. Surrounded by just 12 atoms, it is likely to be the smallest possible size for a transistor – and the hard limit for Moore’s law.

Scientists at London’s Natural History Museum recently launched a citizen science project that will document how wild British orchids are responding to climate changeA few years ago, a paper published in the Journal of Ecology reported that an orchid that grows wild in the UK and parts of Europe was blooming earlier than it was 150 years prior. In that paper, the authors examined field records of flowering times for the early spider-orchid, Ophrys sphegodes, for two time periods and compared the shift in peak flowering times to historical springtime temperature variations (doi:10.1111/j.1365-2745.2010.01727.x). The first time period extracted relevant data from herbarium specimens collected between 1848 and 1958; and the second time period recorded observed peak flowering times for this orchid species in the field between 1975 and 2006.

First case of long-term remission gives scientists new insights into the potential effectiveness of early HIV detection and treatmentA French teenager who was infected with HIV as a baby and given intensive drug therapy in early childhood has lived for more than 12 years without any treatment, raising hopes among scientists searching for a cure for Aids.The case of the 18-year-old was presented at an Aids conference in Vancouver, Canada, by doctors at the Institut Pasteur who treated her. Like the so-called Mississippi baby, she became infected before birth and received drug treatment in the first weeks of her life. Continue reading...

Any truth humans can find ‘out there’ remains speculative, and science and fiction are both still telling storiesAre we alone? There are so many possible ways to begin to answer this question. The backstory on the Fermi Paradox – why we haven’t encountered aliens yet – reads like science fiction. Certainly, the scenarios it sets out are all consigned to the realm of storytelling for now, and even the most logical theories may turn out to be wildly inaccurate. For this reason, the science and fiction of alien contact have much in common, with speculation on the subject sometimes more useful than empirical approaches.The idea of an intertwining between science and fiction on this subject has historical underpinnings. Early scientific papers in the west by the likes of Francis Bacon and Johannes Kepler took the form of “contes philosophiques” or “philosophical tales”, in which the fictional framework of an imaginary or dream journey surrounded some sort of scientific speculation. In the late 1800s, some scientists even presented their findings in the form of poetry. Continue reading...

What family planning solutions did you come up with to maximise the proportion of girls in the population?Hello again. This morning I set you this problem:

This puzzle was all about working out the proportion of girls to boys if a fictional government created a policy to change the ratio of the population. Did you solve it? Did you work out a humane answer?

Alex Bellos ponders how a fictional government planning to increase the proportion of girls to boys would implement a family planning policy – and what would happen if it did. Can you work out how this could be done mathematically ... and humanely? Test your brain power with imaginary Bart and Lisa Simpsons

It’s a family planning puzzle – can you maximise the proportion of girls in the population?This week I’ve got babies on my mind because I’m about to become a dad. And thinking about kids has led me to my favourite conundrum about family-planning:The government – which wants to increase the ratio of girls to boys – introduces a law for all couples that states: Continue reading...

Lockheed to purchase Sikorsky Aircraft, US military’s largest helicopter supplier, in its biggest buy in two decades – which government will examine closelyLockheed Martin, the largest US weapons maker, has agreed to buy United Technologies’ Sikorsky Aircraft unit, the maker of Black Hawk helicopters, for more than $8bn, a source familiar with the negotiations said on Sunday.The two companies plan to announce the deal on Monday before both report second-quarter results on Tuesday, said the source, who was not authorised to speak publicly.

UAE-designed and built craft will set off in 2020 as part of a project aimed at inspiring a new generation within the regionWhen asked if he was nervous, 32-year-old Omran Sharaf was unequivocal. “Of course,” he says. “The reputation of the nation depends on this.”If all goes well, the United Arab Emirates will have a space probe orbiting Mars by 2021 – a first for an Arab world embroiled in endemic conflict. And, as the man leading the Emirates Mars Mission, Sharaf has a lot on his plate. “It’s the first time we go to Mars,” he says. “I have to say, I think the team doesn’t sleep. But it’s something we have to do if we want to progress and move forward. If we can reach Mars, all challenges for the nation should be doable.” Continue reading...

Low profit margins and the difficulty of finding new drugs has led to big pharma shutting down its antibiotics programmes. But now researchers are adopting new approaches to tackle drug-resistant superbugsMatt Cooper, a medical chemist at the University of Queensland, Australia, puffs out his cheeks and scratches his head. He’s trying to explain why the pipeline for new antibiotics is quite so dry. “The problem,” he says, “is that finding new antibiotics is now really, really hard.”It’s a worrying concession given how badly we need new drugs. Drug-resistant superbugs already kill hundreds of thousands of people every year and, according to the Antimicrobial Review (AMR) committee chaired by Jim O’Neill (see box), if left unchecked they will kill 10 million of us every year by 2050. That’s more than will be killed by cancer, diarrhoeal disease or road traffic accidents. Continue reading...

After ‘nano’ and ‘quantum’, epigenetics, an important branch of biology, is the latest scientific buzzword to be hijacked by quackeryThe legion purveyors of flapdoodle love a real but tricksy scientific concept that they can bolt their pernicious quackery on to. “Quantum” is surely the biggest offender, offering up some mystical scienceyness, none more so than in “quantum healing” – an unfathomable extension of reiki, which, let’s face it, is already graphene-thin flimflam. The annexing of this word from fundamental physics ranges from washing-powder branding to the theory of mind. “Quantum consciousness” is an idea that has generated some serious discussion over the years, but for me slots squarely into the category of “using one thing we don’t understand to explain another”.Lots of real scientific terms – such as “neuro” or “nano” – get borrowed for a spot of buzzword scienceyness. Epigenetics is a real and important part of biology, but due to predictable quackery, it is threatening to become the new quantum. Continue reading...

The dramatic images of vast ice plains on Pluto beamed to Earth last week prove that it is regions on the edge of the solar system - long thought to be inert wastelands - that are the most exciting for scientistsFor a world perched at the outer edge of the solar system, Pluto caused considerable excitement last week when it was revealed to be a place of unexpected dynamic activity. The New Horizons probe – after a 10-year voyage to reach the dwarf planet – was able to show that it contains great plains of ice that could have formed only 100 million years ago, a mere twinkling of a cosmic eye. Continue reading...

Almost - but not quite - buried on the icy plains of Pluto this week, the Large Hadron Collider revealed a completely new type of particle. What does that tell us?

The psychologist and bestselling author of Thinking, Fast and Slow reveals his new research and talks about prejudice, fleeing the Nazis, and how to hold an effective meetingDaniel Kahneman is the very definition of unassuming: a small, softly spoken man in his 80s, his face and manners mild, his demeanour that of a cautious observer rather than someone who calls the shots. We meet in a quiet spot off the lobby of a London hotel. Even then I have trouble catching every word; his accent hovers between French and Israeli and his delivery is quiet, imbued with a slightly strained patience, helpful but cautious.And yet this is a man whose experimental findings have shifted our understanding of thought on its axis – someone described by Steven Pinker as “the world’s most influential living psychologist”. With his long-time collaborator Amos Tversky, who died in 1996, he delineated the biases that warp our judgment, from figuring out if we can trust a prospective babysitter to buying and selling shares. In 2002 he was awarded the Nobel prize in economics, a testament to the boundary-busting nature of his research. Continue reading...

‘I think the solar system saved the best till last’ says lead investigator as Nasa states only 1-2% of data from mission to dwarf planet has been downloaded so farPluto has giant plains threaded with trenches and studded with hills, Nasa revealed on Friday, as researchers of the New Horizons mission released a new image of the surface and discussed the findings of the growing data they are gathering from the dwarf planet.

Simon Jenkins parrots a cry that I have heard a few times during my career as a research scientist in high-energy physics (Pluto trumps prisons when we spend public money, 17 July). He is unimaginatively concerned that the £34m a year spent by the UK at Cern (and a similar amount per year would have been spent on the New Horizons probe to Pluto) is not actually money well spent.Yet I read his article online using the world wide web, which was developed initially by and for particle physicists. I did this using devices with integrated circuits partly perfected for the aerospace industry. The web caused the longest non-wartime economic boom in recorded history, during the 90s. The industries spawned by integrated circuits are simply too numerous to count and would have been impossible to predict when that first transistor was made in the 50s. It is a failure of society that funnels such economic largesse towards hedge-fund managers and not towards solving the social ills Mr Jenkins rightly exposes. Continue reading...

Those attacking Jeremy Corbyn for supporting the NHS provision of homeopathy are helping to entrench the perceived elitism of mainstream medicineThis week, critics of Jeremy Corbyn dug up a 2010 tweet in which he justified his signing of a parliamentary motion in favour of NHS provision of homeopathic treatments (his voting record, including votes in favour of scientific funding and against the use of the designation of “doctor” for complementary therapists is available here).Although I am not a proponent of homeopathy, the response to this “revelation” has been discouraging. In particular, Ian Dunt of politics.co.uk used belief in homeopathy as a test not only for idiocy, but also for morality. Dunt suggests that in holding a belief in homeopathy (or any other “enemy of objective truth”), proponents are showing that they fail to understand the world and rejecting objectivity in favour of experiential evidence or intuition.

As a recent study proves, turning anything fun into a chore can ruin it, so how can we enjoy things without the obligation trap?A new study of the link between sex and happiness has been getting lots of media attention – presumably because it’s about sex, and for the staff of traffic-hungry media organisations, the experience of receiving vast numbers of clicks on a story about sex is, ironically and poignantly, better than sex. The headline finding is that more sex doesn’t automatically make you happier; in fact, contrary to the assumptions of most researchers, and for that matter most sex-havers, it makes many feel worse.Here’s how the experiment worked: half of the 128 couples involved were instructed to have twice as much sex as usual, then all participants filled out a survey, about their sex lives and happiness levels, every day for three months. Perhaps you can spot the problem here? (To be fair, the study’s authors were well aware of it.) A better way of putting the results might be as follows: when four academics from Carnegie Mellon University in Pittsburgh tell you to have more sex, and fill out a tedious form every day, it doesn’t make you happier.

Self-tracking apps and devices allow us to monitor our behaviour, but we should be cautious in expecting them to drive improvements in our wellbeing“Fitter, happier, more productive” is a cynical line even by Radiohead’s standards. But the band’s song, released in 1997, did manage to predict the near future: an explosion of apps and wearable devices devoted to monitor people’s lives with the purpose of boosting self-control and suppressing naughty habits. This movement, referred to as the quantified self, revolves around enhancing self-knowledge through numbers, in particular data capturing our everyday behaviours, habits and activities.As the Economist noted when the trend began to make waves, its users “are an eclectic mix of early adopters, fitness freaks, technology evangelists, personal-development junkies, hackers and patients suffering from a wide variety of health problems. What they share is a belief that gathering and analysing data about their everyday activities can help them improve their lives – an approach known as self-tracking, body hacking or self-quantifying.” Continue reading...

From Brangelina to Brexit, the ugly mating of elegant words has gone too far. So don’t be a Camerunt: cease portmanteauing immediatelyA little party trick I use to bore girls is to pepper them with exceptionally dry factlets about the English language. It involves me saying things like: “Yo hey what up: did you know the reason we have a different word for the flesh of an animal and the animal itself is because of the French invasion of 1066, when French became the language of the courts, and they made many decadent boeuf dishes?” I wiggle closer and say: “Did you know there is a direct line between the plague and the invention of the aspirational middle class and the invention of thesauruses? That the plague basically caused thesauruses?” Lean right in and say: “Do you know about William Labov’s department store study, because it is actually very interesting?” This approach, I don’t mind telling you, has a 100% success record – at boring them.But I’ve found my niche now, Guardian readers, in you, and you cannot pretend you have a boyfriend or sprint away to an awaiting Uber so let’s talk about portmanteaus, shall we? Portmanteau words – imagine I am sliding a single vodka-coke towards you right now – portmanteau words are two words shunted together, like a cut-and-shut car. They are fun. Continue reading...

When a public figure makes a mistake, there’s probably something we can all learn from itThree years ago, I was working alone in the lab when the phone rang. On the other end, much to my surprise, was a Nobel prize winner asking to collaborate. That phone call led to a successful research project, the results of which were published earlier this year.I recall the initial meeting we had, and voicing my concerns as to how I would be credited in the final publication - should it be successful - as it would require a reasonable amount of my time and access to methods that I was still in the process of developing. His answer was simple: look at his publication record and I would see he treats his collaborators well. Something I too can now attest. This kind of discussion is normal between scientists to establish boundaries; but importantly, the differences in the stages of our careers and our accolades never came into the discussion. Instead, any credit was discussed on the merits of what each of us could contribute to that specific piece of research. Continue reading...

Safety protocol put in place for only the fourth time in 16-year history of ISS as crew seeks protection from potentially lethal space debrisA piece of space junk threatened to crash into the international space station, forcing the three astronauts to seek emergency shelter.For nearly an hour on Thursday, the American and two Russians hunkered down in their Soyuz capsule, which is docked to the space station, in case they had to make a quick getaway. The fragment from an old Russian weather satellite ended up passing harmlessly, about 1½ miles (3kms) away. Continue reading...

The SKA, which will be split between sites in Australia and South Africa, will peer back into the ‘dark ages’ of the universe. No one knows what it will find there• Radio silence in Western Australia for most powerful telescope in historyThe Square Kilometre Array (SKA) is a huge project designed to sweep away many of the current roadblocks to astronomical progress. These include searching for the first celestial objects to form in the universe, investigating whether we need to develop a new theory of gravity, and looking for the building blocks of life in space.After the big bang around 13.8bn years ago, the universe was nothing but a vast cosmic ocean of gas. There were no stars or planets. Nothing was shining and astronomers refer to this time as the dark ages. During this time, matter was gradually pulling itself into the first celestial objects, but no one knows what these objects were. Continue reading...
