My partner, however, always assumed that one day he would be a dadI didn't become a childfree woman. I was born childfree, much like everyone else, then I simply stayed that way. There was no need to go through a future-mother phase to know that in my home there would be no chirpy children's laughter or tippety-tap of bare toddler feet.Poor David then, my partner. He most definitely was in his future-father phase when we met, aged 20, 21. Continue reading...
If departing the EU has failed to deliver, why is the UK still so divided? Seven years on, we ask behavioural psychologists if cognitive dissonance can be overcomeOne of the most significant political events of the past few months, it has seemed to me, wasn't strictly a bit of politics at all, but an emotional catch and quaver in the voice of a politician. The politician was the Conservative MP Steve Baker and the sudden sob in his throat came about during a TV interview about the efforts to resolve the Northern Ireland protocol.Baker, you will recall, was one of the most strident voices in the Brexit argument, a leader of the Tory European Research group, the ERG, which frustrated Theresa May's efforts to find a compromise deal with the EU. The sob in his voice and the tears in his eyes prefaced a short, heartfelt confession about the extreme private stress that those Brexit machinations - and subsequent arguments over Covid lockdown - had caused him. Speaking subsequently to the Times, Baker expanded on that state of mind. I felt absolutely worthless," he said. I felt repugnant, hateful, to blame for all of the troubles that we had, absolutely without any joy, constantly worried about everything to the point of mental torment. A constant state of panic attacks and anxiety. It's not a state anyone should live in." Continue reading...

The Egyptian-American scientist on falling in love with the stars, the problems faced by women of colour in her field, and her preventive double mastectomyEgyptian-American astrophysicist Sarafina El-Badry Nance's debut memoir, Starstruck, offers a window on what it is like growing up to be a scientist today as a woman of colour. Nance, 30, is a passionate communicator of cosmology, and an advocate for women's health, after a preventive double mastectomy. The book intertwines her personal story with explanations of what we know about the universe. Nance is completing her PhD at the University of California, Berkeley, where she is studying exploding stars or supernovae.Isn't this a young age to be writing a memoir? You still have so much of your personal and professional life ahead of you.
Two new shows at the festival question senses of hearing and sight in engaging and eccentric waysSeeing is believing, right? That is a phrase used repeatedly by Mamoru Iriguchi and co-star Gavin Pringle in What You See When Your Eyes Are Closed/What You Don't See When Your Eyes Are Open (). It is an amusingly hand-stitched investigation into ways of seeing, performed in one of Summerhall's small basement rooms at the Edinburgh fringe. The production treats the challenges faced by people who are blind or visually impaired as a creative resource. The costumes are bold, the lines distinct, the faces larger than life and, in the most idiosyncratic way, everything is captioned and described. It is surreal and, despite its deliberate repetitions, never predictable.If seeing really was believing, we would accept that the man in the outsize Mamoru Iriguchi mask, his grey suit outlined in thick black lines, his enormous glasses showing sleeping eyes, was indeed Mamoru Iriguchi. We would also surmise that the giant cyclops standing in the centre of the room, in a bushy coat of orange tassels and a purple head concealing a live video projector behind its gigantic single eye, was his husband, Gavin.

From a heart-shaped stem cell colony to purple gold and science candies', these are the 12 finalists for the 2023 Australian Institute for Bioengineering and Nanotechnology image contest. Each year in the lead up to National Science Week, researchers at the University of Queensland's AIBN have a competition to find the best image taken using imaging equipment and microscopes. This year's winner will be announced on 14 August
Creation of hundreds of signs aimed at making conversations about climate more accessible for deaf peopleScientists and British Sign Language users have created new signs for greenhouse gases, carbon footprint, and more than 200 other environmental terms.It is hoped the effort to rewild" BSL will make climate and biodiversity science more accessible for deaf people.Carbon footprint: Left hand as a C shape with right hand fingers moving away from the left hand to resemble carbon being released to the environment.Greenhouse gases: Both hands in circular shapes move around to represent gases, then put the left hand at the horizontal position and move the right hand, with the index finger pointing, down and back up to the left hand to show the sunlight reflecting on Earth's surface.Carnivores: Two five-fingered claws coming together as sharp teeth.Herbivores: Closed fists together, palms facing, with right hand on top + slide knuckles against each other in a circular teeth grinding" motion.Omnivores: Sign for carnivores" + sign for herbivores"Cetaceans (marine mammals including whales, dolphins and porpoises): Bring hands together to form a circle that faces the ground (sign for group") + link thumbs, palms facing the body, and fan palms up and out to resemble whale tail fin".Natural selection (the natural process whereby the best-adapted individuals survive longer, have more offspring, and thereby spread their characteristics): Two index fingers moving forward and the right hand, index still pointed, falls down", and the left index finger continues to stay upright and moves forward.Rewilding (the process of creating habitats that are similar to the conditions present before the natural habitat was changed by human actions): Two flat hands, palms facing down, then drop palms while pulling hands back (sign for habitat" but upside down). Then right hand at a distance from the body turns from palm facing up to down. Continue reading...
Experts closing in on potentially identifying new force after surprise wobble of subatomic particleThe tantalising theory that a fifth force of nature could exist has been given a boost thanks to unexpected wobbling by a subatomic particle, physicists have revealed.According to current understanding, there are four fundamental forces in nature, three of which - the electromagnetic force and the strong and weak nuclear forces - are explained by the standard model of particle physics.

Lioness's penalty against Nigeria makes Women's World Cup record and beats fastest strike of Premier League last seasonArms out, leg cocked: as England's Chloe Kelly took her penalty against Nigeria the forward was, she later said, confident of scoring. She not only won the game for the Lionesses, she set the record for the fastest shot in the Women's World Cup so far.According to data from the official match ball, the shot on Monday reached 110.79km/h (69mph) - a speed that beats the most powerful strike of the 2022-23 Premier League campaign, by West Ham's Said Benrahma, that clocked in at 107.2km/h (66.6mph).

Everybody thinks it's an amazing superpower, but there's another side to itRecently, I was sitting on a tightly packed plane as it circled up to 19,000ft. It was making loads of noise, and I could see the people around me were scared. But I felt nothing.In 2005, I was diagnosed with Cushing's syndrome, after years of misdiagnosis - doctors would often tell me I was just overweight. Cushing's is a rare condition that affects one to two people in a million per year in the UK, and is caused by the body producing too much cortisol. Cortisol is a hormone that regulates a range of processes, including the stress response; if it's not treated, it can be very serious. Symptoms can range from severe weight gain to high blood pressure. Continue reading...
Although designers do have a lot of power, AI is just a tool conceived to benefit us. Communities must make sure that happensSuperpower. Catastrophic. Revolutionary. Irresponsible. Efficiency-creating. Dangerous. These terms have been used to describe artificial intelligence over the past several months. The release of ChatGPT to the general public thrusts AI into the limelight, and many are left wondering: how it is different from other technologies, and what will happen when the way we do business and live our lives changes entirely?First, it is important to recognise that AI is just that: a technology. As Amy Sample Ward and I point out in our book, The Tech That Comes Next, technology is a tool created by humans, and therefore subject to human beliefs and constraints. AI has often been depicted as a completely self-sufficient, self-teaching technology; however, in reality, it is subject to the rules built into its design. For instance, when I ask ChatGPT, What country has the best jollof rice?", it responds: As an AI language model, I don't have personal opinions, but I can provide information. Ultimately, the question of which country has the best jollof rice is subjective and depends on personal preference. Different people may have different opinions based on their cultural background, taste preferences, or experiences." Continue reading...
DNA technology confirmed Talpa hakkariensis and Talpa davidiana tatvanensis as distinct from other molesScientists have identified two types of mole that they believe have been living undiscovered in Turkey.DNA technology confirmed the creatures were biologically distinct from other moles. Both inhabit mountainous regions in eastern Turkey and can survive in temperatures of up to 50C (122F) in summer and under 2 metres (about 6ft) of snow in winter. Continue reading...
A Soyuz-2 Fregat rocket carrying a lunar landing craft blasted off on what Russia hopes will be its first successful moon landing mission in nearly 50 years. The unmanned Luna-25's mission to the moon that is expected to take about five days and will seek to land near the south pole of the moon, collecting geological samples from the area. India's Chandrayaan-3 space probe entered the moon's orbit earlier this week, and will also explore the water-rich area near the south pole
Virgin Galactic has succeeded in flying three tourist into space for the first time. They were former Olympian Jon Goodwin, Antiguan health and wellness coach Keisha Schahaff and her 18-year-old daughter, Anastasia Mayers. "You are so much more connected to everything than you would expect to be. You felt like a part of the team, a part of the ship, a part of the universe, a part of Earth," said Anastasia.
Virgin Galactic's VSS Unity, the reusable rocket-powered space plane carrying the company's first crew of tourists to space, has successfully launched and landed. Aboard the spacecraft were six individuals in total, including three private passengers. Following liftoff, Virgin Galactic's carrier plane, VMS Eve, transported VSS Unity to an altitude of about 44,300ft. Eve then dropped Unity, which fired its own rocket motor and ascended to suborbital space
Team converts polyethylene into fatty acids, soap's main ingredient, but say it is not panacea for plastic pollutionScientists have discovered a method to give new life to old plastic - by converting it into soap.Plastics are chemically similar to fatty acids, which are one of the main ingredients in soap. For Guoliang Liu, an associate professor of chemistry at Virginia Tech and author of the paper published in the journal Science, this similarity suggested it should be possible to convert polyethylene into fatty acids, and then into soap. The problem was size: molecularly, plastics are very large, about 3,000 carbon atoms long, whereas fatty acids are much smaller. Continue reading...
My friend Bob Reid, who has died aged 92, was a cosmic ray physicist who studied these mysterious particles in Jamaica, on the moors of North Yorkshire and at the South Pole.Bob also had a fascination with boomerangs and was a member of the British Boomerang Society. In December 1988, while searching for cosmic rays from Supernova 1987A, he threw one around the South Pole, which technically stayed aloft for 24 hours and nine seconds as it travelled through 24 time zones.

Cosmologist who explored the clustering of galaxies as a way of establishing the distribution of dark matter in the universeBetween 1984 and 1992 the cosmologist Nick Kaiser, who has died of heart failure aged 68, created many of the ideas now used by astronomers to map the large-scale distribution of dark matter in the universe. His analysis of the clustering of galaxies and the distortion of galaxy shapes by gravitational light deflection are at the heart of the leading modern cosmological experiments, particularly the recently launched Euclid satellite.Kaiser's research concentrated on the large-scale structure of the universe. Galaxies such as our own, the Milky Way, are congregated in a vast pattern of density fluctuations - superclusters that extend for at least 100m light years. All this structure probably represents the relic of primordial fluctuations that collapsed under their own gravity, generating galaxies and the stars and planets within them. We see these patterns in the clustering of the galaxy distribution, but much evidence tells us that the galaxies are embedded in invisible underlying dark matter, which dominates the gravity - dragging gas with it, which in turn forms into the stars of the visible galaxies.

Previously unknown Tutcetus rayanensis is just 2.5 metres long and oldest of ocean-living whales recorded in AfricaA pint-size whale that lived around 41m years ago has been discovered by palaeontologists in Egypt, who say the species may have lived a short, speedy life.Researchers say they unearthed the fossils near Wadi el-Hitan in Egypt, a site where many fossils of ancient whales can be found. At first, they said, it was unclear what they had found. Continue reading...
Vets receive medication originally meant for people amid virulent feline coronavirus that has killed thousands of catsVeterinary services in Cyprus have received a first batch of anti-Covid pills, from a stockpile originally meant for humans, as efforts intensify to stop the spread of a virulent strain of feline coronavirus that has killed thousands of cats.The island's health ministry began discharging the treatment on 8 August - long celebrated as International Cat Day - in what is hoped will be the beginning of the end of the disease that has struck the Mediterranean country's feline population.

Global accord aims to avoid the damage caused during Covid-19 and ensure vaccines and medical equipment are distributed equally to allCovid-19 caught the world unprepared; the scramble it prompted for treatments, tests, protective equipment and vaccines favoured the world's richest nations. To avoid the same thing happening in future pandemics, a group of world leaders has proposed a pandemic treaty, which is being negotiated in a series of international meetings hosted by the World Health Organization (WHO).The draft treaty is aimed at ensuring equity in distributing all that is needed to handle a future pandemic, instead of the coronavirus free-for-all.

There are more people working on it, so it's bringing in people from different disciplines with new ideas." Continue reading...
Researchers hail very important discovery' that sheds light on unexplored Italian seabedAfter a weeks-long deepsea expedition, researchers from several universities around the world have discovered three underwater volcanoes off Sicily's south-west coast.According to scientists, the newly discovered volcanoes are at least 6km wide and rise more than 150 metres above the surrounding seabed. They join a series of other volcanic cones discovered in 2019 by the National Institute of Oceanography and Experimental Geophysics (OGS) in the marine area between Mazara del Vallo in the Sicilian province of Trapani and Sciacca, a town in Agrigento.

Despite recent scandals of research misconduct and error, the academic world still seems determined to look the other wayScientific misconduct has enjoyed some limelight lately. The president of Stanford, Marc Tessier-Lavigne, resigned last month after a series of investigations exposed serious problems in his research; an independent review of Tessier-Lavigne's work found no evidence that he falsified data himself but concluded that his research failed standards of scientific rigor and process" and that he failed to correct the record on multiple occasions.And in June it was revealed that a scholar at Harvard Business School, Francesca Gino, was accused of having falsified research about - wait for it - honesty.

It's very doable', according to the man who co-founded the submersibles company OceanGate. In fact, it's just like a caravan holiday!Guillermo Sohnlein is a man of many ideas. One of those ideas was OceanGate: the company that used to send people to the bottom of the sea in submersibles until one of those submersibles imploded, killing all five people on board, including Sohnlein's co-founder. It's 10 years since Sohnlein left the company, but after a tragedy like that you'd think he'd want to stay away from risky ventures for a while. But no, the businessman recently told Insider that he is intent on colonising Venus. This isn't some lofty vision of the far future: he wants to send 1,000 people to Venus's atmosphere by 2050. He lays out all his plans in an extremely unimpressive website for his foundation called Humans2Venus.While all this may sound completely ridiculous, don't worry: Sohnlein has looked into the logistics and concluded that getting to Venus is very doable". I think it is less aspirational than putting 1 million people on the Martian surface by 2050," he mused. You should trust him on this - he's been researching the matter for a very long time. I think I've been driven to help make humanity a multiplanet species since I was 11 years old," he told Insider. I had this recurring dream of being the commander of the first Martian colony." I've had a recurring dream that I forgot to do any of my maths homework for a year and then I had to sit a test, but I haven't spun that into a business venture.Arwa Mahdawi is a Guardian columnist Continue reading...
Study also finds each additional 1,000 steps daily are associated with a further 15% reduction in riskWalking just 4,000 steps a day may reduce your risk of dying from any cause, the largest analysis to date suggests - although the more you walk, the greater the health benefits.The idea that a sedentary lifestyle is linked to poorer health is now well established, yet, until now, it has been unclear what the optimal number of steps people should aspire to is, or if there is an upper limit beyond which further health gains are minimal.

Research suggests behaviour may reflect evolutionary response to previous outbreaks of diseaseAerial surveys of the North Sea have revealed that seals practise social distancing - and the discovery may have profound implications for the spread of disease among the marine mammals.In a paper published today by the Royal Society, researchers conducting censuses of grey and harbour seals detail new evidence that the two species not only maintain distances between their own kind (unlike walruses, for instance, who cluster close together) but also that this behaviour may reflect an evolutionary response to viral susceptibility".

Uncertainty over Britain's post-Brexit version of the CE mark has hampered the development of medical devices, says Roger Bayston. Plus a letter from Ian WhiteThe enormous waste of resources due to red tape described by Polly Toynbee (Business is haunted by Brexit - and this safety mark fiasco is its latest nightmare, 4 August) is not just confined to British business - it has severely affected UK research in the area of medical devices.Scientists need to partner with manufacturers in order to get these devices out of the lab and into the clinic. But we and others have experienced our industrial partners withdrawing support and pulling out of agreements because it has been simply too costly to embark on double certification of potential products.

What are the best exercises to reduce your blood pressure? The plank and the wall sit. Here is how to do them - and some other great poses - whatever your current fitness levelCould the secret to lifelong health be ... staying still? It sounds counterintuitive, but in a recent study, researchers assessing 270 randomised controlled clinical trials (involving more than 15,000 participants) found that isometric exercises, in which muscles are working but remain motionless, were more effective than a range of other options for reducing blood pressure.To be clear, aerobic exercise training, dynamic resistance training, combined training and high-intensity interval training all helped, compared with non-exercise control interventions. But isometrics were most likely to reduce blood pressure, with full-body movements such as the wall squat showing bigger benefits than moves such as hand-gripping or leg extensions.

The emergence of a possible link between air pollution and antibiotic resistance shows why action to clean up air is so badly neededA decade ago, Britain's top health official issued a grim warning: antibiotic resistance posed an apocalyptic threat, with patients having simple operations at risk of dying from routine infections that could no longer be treated.Sally Davies, then the chief medical officer for England, said global action was required to fight antibiotic resistance and fill a drug discovery void by researching and developing medicines to treat mutating infections.

We might be able to genetically engineer something like woolly mammoths, but is it a good idea?We may weep for the dodo, but could and should we bring this lovely bird back from the dead? De-extinction is the science of restoring lost species and it has been in the news, sporadically, for decades.The story in modern times began in 1990 when Michael Crichton published his science fiction novel Jurassic Park, in which he imagined a world where scientists were able to bring dinosaurs back to life. Crichton had trained as a biomedical scientist, so he was aware of the then new polymerase chain reaction (PCR) technology that was revolutionising life-sciences labs. PCR enabled molecular biologists to make millions or billions of copies of DNA very quickly meaning that only tiny samples were needed. Continue reading...

Our inability to confidently predict sea level rise between an extremely challenging two metres and a civilisation-ending 10 metres is an exemplar of the problem facing researchersThese last few months have been a turbulent time to be an oceanographer, particularly one specialising in the vast Southern Ocean around Antarctica and its role in our climate. The media has been awash with stories of marine heatwaves across the northern hemisphere, the potential collapse of the Atlantic meridional overturning circulation by mid-century and the record-breaking deficit in Antarctic sea ice emerging this southern winter. Alongside heatwaves and bushfires in North America and southern Europe, flooding in China and South American winter temperatures above 38C, the climate has moved from a future problem" to a now problem" in the minds of many.The global climate is one hugely complex interconnected system. While the Antarctic and Southern Ocean are far removed from our daily lives, they play an oversized role in this system and the future climate that concerns humanity now. Global warming" is really ocean warming". The atmospheric temperature change, the 1.5C Paris target we are now perilously near to exceeding, really is only a few percent of our total excess trapped heat. Almost all the rest is in the ocean and it is around Antarctica that it is predominantly taken up. How this uptake may change in the future as winds, temperatures and ice shift is a critical scientific, and human, question. Continue reading...
