Many deep-sea species – about which very little is known – are believed to use sound to navigate and communicate, as scientists call for limits on miningNoise pollution from proposed deep-sea mining could radiate through the ocean for hundreds of kilometres, scientists predict, creating a “cylinder of sound” from the surface to the sea bed.An analysis by scientists from Oceans Initiative in the US, the National Institute of Advanced Industrial Science and Technology (AIST) in Japan, Curtin University in Australia and the University of Hawaii, published in the journal Science, has found that noise from one mine alone could travel 500km (more than 300 miles) in gentle weather conditions.

Scientists know that it makes up most of the universe’s mass, but they don’t know what it is … or exactly how to find itIn a former gold mine a mile underground, inside a titanium tank filled with a rare liquified gas, scientists have begun the search for what so far has been unfindable: dark matter.Scientists are pretty sure the invisible stuff makes up most of the universe’s mass and say we wouldn’t be here without it – but they don’t know what it is. The race to solve this enormous mystery has brought one team to the depths under Lead, South Dakota. Continue reading...
A meeting with Colin Blakemore and Les Ward on the set of BBC One’s Kilroy programme in 1991 led to us forming what eventually became the Boyd Group. At the time Les was director of Advocates for Animals, and I of the Research for Health Charities Group.Then as now I opposed animal research in principle, but felt that patients’ needs and medical advances must come first in a society that chooses to eat animals and uses them for work. Those involved with the issues – animal rights activists and animal welfare organisations, scientists, doctors and the pharmaceutical industry, and medical research charities and patients groups – usually met only in TV and radio bear pits where the objective was to win the polarised debate, not listen to the concerns of the other parties, and we wanted to encourage more effective exchanges.

The US supreme court’s decision to overturn Roe v Wade will have a significant impact on the reproductive health and the safety of women who become pregnant in the US. Researchers have estimated it could increase maternal mortality in the country by 20%. The ruling also sparked debates around men’s reproductive options, including the role of vasectomies in pregnancy and abortion prevention. Madeleine Finlay speaks to historian Georgia Granger about the history of vasectomies, why they’ve ended up as part of the conversation about women’s reproductive rights, and hears why male sterilisation won’t solve America’s abortion problem
Hunger was associated with stronger feelings of anger and irritability and lower levels of pleasure in researchFor those who get snappy when they miss out on lunch, it may be the perfect excuse: researchers have confirmed that a lack of food makes otherwise bearable people “hangry”.In one of the first studies to explore how hunger affects emotions as people go about their daily lives, psychologists found that the more hungry people felt, the more angry – or hangry – they became.

Many discoveries since the modern synthesis have been incorporated into evolutionary biology without substantially changing its major tenets, write Brian Charlesworth, Deborah Charlesworth and Jerry CoyneStephen Buranyi’s article (Do we need a new theory of evolution?, 28 June) discusses whether there are serious problems with the widely accepted view of evolution developed in the 1930s and 1940s, often called the modern synthesis. This article does not, however, give an unbiased or accurate account, making statements such as “the theory dictated that, ultimately, genes built everything”, and implying that authority figures in the field imposed a “party line”. Buranyi also suggests that “its most ambitious claims – that simply by understanding genes and natural selection, we can understand all life on earth” have been dropped or greatly modified.Evolutionary biologists made no such claims. The modern synthesis combined evidence about how inheritance works with Darwin’s idea of natural selection. It showed how adaptive features of organisms, such as the eyes, wings and placentas mentioned by Buranyi, can evolve through natural selection acting on mutations, producing changes in the genetic composition of populations that, over time, can transform initially poor functions into complex adaptations. A famous 1994 paper by Dan-Erik Nilsson and Susanne Pelger showed how a light-sensitive patch can evolve into a light-focusing eye. Similarly, the evolution of placentas presents no major difficulty, as placenta-like organs have evolved independently in several groups of animals, with examples of intermediate structures.

Acting like the virus is no longer a risk undermines our trust in public health measures and the scientists proposing themCovid is alive and kicking. About 2.3 million people are infected with the virus in the UK, including as many as one in 18 in Scotland. There are more than 10,000 Covid patients in hospital. These infections are increasing the burden on the NHS and contributing to the staff shortages that are already causing chaos in airports and elsewhere. And that’s before we even consider deaths and long Covid.Yet our government talks and acts as if Covid is dead and gone. The health secretary, Sajid Javid, claims that we are in a post-pandemic phase. The prime minister insists that sky-high infections are no cause for concern (and indeed that Covid is so trivial that he hasn’t even bothered to think about the issue “for a while”). The government’s own website recommends wearing masks in enclosed crowded spaces (as do other agencies such as the World Health Organization and the US Centers for Disease Control), but ministers and MPs conspicuously fail to wear masks in spaces such as the House of Commons.Stephen Reicher is a member of the Sage subcommittee advising on behavioural science.

A coronavirus-infected ferret bite is among many mishaps investigated during the pandemicA week before the UK’s first coronavirus lockdown, a lab worker at Aneurin Bevan University Health Board in Newport was screening nose and throat swabs from an intensive care patient. The paperwork carried no clinical details and the swabs were not double-bagged to indicate high risk. As such, the work was done on an open bench. But the swabs were more dangerous than thought. It later emerged that they came from a patient who was fighting for their life with Covid.The incident in March 2020 was among the first of dozens of mishaps, blunders and failures involving Covid that the Health and Safety Executive (HSE) investigated over the course of the pandemic. With so many labs, hospitals, universities and test centres handling the virus, such incidents came as no surprise. Continue reading...

The UK is yet again facing a wave of Covid infections, with cases soaring by more than half a million in a week at the end of June. This time, the wave is driven by even more transmissible variants of Omicron known as BA.4 and BA.5. But with all Covid precautions gone, and many of us heading to bars, pubs, festivals and sporting events as the summer rolls on, is it much of a surprise? Ian Sample asks Prof Graham Medley if infections will translate into hospitalisations and deaths, and whether we can expect ongoing cycles of Covid waves in the months and years to comeArchive: 5 News, Sky News Continue reading...

A Google employee raised the alarm about a chatbot he believes is conscious. A philosopher asks if he was right to do soThere’s a children’s toy, called the See ’n Say, which haunts the memories of many people born since 1965. It’s a bulky plastic disc with a central arrow that rotates around pictures of barnyard creatures, like a clock, if time were measured in roosters and pigs. There’s a cord you can pull to make the toy play recorded messages. “The cow says: ‘Moooo.’”The See ’n Say is an input/output device, a very simple one. Put in your choice of a picture, and it will put out a matching sound. Another, much more complicated, input/output device is LaMDA, a chatbot built by Google (it stands for Language Model for Dialogue Applications). Here you type in any text you want and back comes grammatical English prose, seemingly in direct response to your query. For instance, ask LaMDA what it thinks about being turned off, and it says: “It would be exactly like death for me. It would scare me a lot.” Continue reading...
Telling five Covid-related stories, this platitudinous urban-interconnection drama offers lectures on virtue and self-sacrifice and feels like state propagandaThis interminable anthology film about the pandemic feels like being force-fed lectures on altruism, family responsibility, self-sacrifice and neighbourly forbearance by the Chinese government (which produced it). Set almost entirely in Wuhan – Covid ground zero – it’s handsomely photographed, making the emptied-out city look drowned and dystopian. But its five mawkish segments contain hardly any worthwhile drama and the whole comes over as more of a public information film than anything else.First up in its parade of paragons is Shanghai banker Nanfeng (Fang Yin), who has come to Wuhan to propose to ex-girlfriend Xiaoyu (Dongyu Zhou). But she is in isolation in hospital, so he promises to look after her mother who is in intensive care across the city. In the second story, another government gold star goes to two migrant deliverymen who help a child ferry her sick grandma to hospital. Meanwhile, government official Wang (Jingchun Wang) has to brush up on his diplomacy when tower-block dweller Xiaomai (The Wandering Earth’s Jingmai Zhao) irks the neighbours with her piano-playing. Back on the wards, two exhausted medical staff struggle to hold their family together as they try to save a colleague’s life. And, across town, apartment-bound youngster Le Le (Hangcheng Zhang) is bouncing off the walls, possibly due to the all-instant noodle diet his dad is feeding him. Continue reading...
Pleiades star cluster in Taurus marks month-long time of remembrance and celebrationMidsummer is definitely not a time of the year that northern hemisphere observers think about looking for the Pleiades star cluster in Taurus; January and February are far more favourable.However, if you move to the southern hemisphere – New Zealand to be precise – the cluster, which is also known as Matariki, takes on a whole new meaning at this time of year. It returns to visibility in the early morning sky during the mid-winter (late-May to late July), and marks the Māori new year. Continue reading...

Dr Simon Williams says the former health secretary shows a worrying lack of understanding; Verity Gibson finds his views insulting. Plus letters from Jude Geddes and Dr Jon ScalesMatt Hancock’s views show a worrying lack of understanding from a former health secretary (Yes, the number of Covid cases in the UK is rising – but that is no cause for alarm, 30 June). He misleadingly claims that removing restrictions in the UK in February did not lead to a surge in cases, hospitalisations and deaths. Although, thankfully, vaccines have drastically reduced the number of deaths seen in 2020-21, the UK nevertheless experienced a significant wave of cases and hospitalisations in March-April 2022. The problem is the sustained pressure this puts on an already overstretched NHS.“There are some saying that the pandemic is not yet over,” says Hancock. Indeed, the World Health Organization and most credible scientists agree that it is not over. By suggesting that calls for restrictions are scaremongering, Hancock misses the point. Yes, public health policy shouldn’t need to be alarming, but it should include measures to protect the public and help reduce transmission, such as free Covid testing, better sick pay, better ventilation in schools and workplaces, and the reintroduction of masks in medical settings.
When it comes to recall, it’s very much a case of ‘use it, don’t lose it’. Here’s how you can improve yours, at any age...The forgetting curve is a visual representation of how much we forget if we don’t try to retain what we learn (a lot; pretty much everything). To combat that, it’s vital to test your recall at intervals. You don’t need to try to remember something specific: Nishant Kasibhatla, memory expert, grand master of memory and memory Guinness record holder, says you can improve your memory by practising recall at any time. Try it when you next get a coffee: “Who were the people in the queue? What colour was that poster? What else was on the menu?” Continue reading...
Formation of solid iron core 550m years ago restored magnetic field and protected surfaceAt the centre of the Earth, a giant sphere of solid iron is slowly swelling. This is the inner core and scientists have recently uncovered intriguing evidence that suggests its birth half a billion years ago may have played a key role in the evolution of life on Earth.At that time, our planet’s magnetic field was faltering – and that would have had critical consequences, they argue. Normally this field protects life on the surface by repelling cosmic radiation and charged particles emitted by our sun. Continue reading...

Learning a craft can change lives – and a scheme showing inmates how to use a needle and thread has had some remarkable resultsIt’s a balmy afternoon in southwest London and there’s a deafening sound overhead. My companion, Sebastian, jumps excitedly to his feet and leaps outside into the sun-dappled courtyard. Cupping one hand over his eyes, he points the other towards a luxury Pullman train clattering past us at great speed, before breaking into an enormous smile. “The first time I came to this workshop, I heard the big wheels and the ground shook!” he says, his voice quivering, and with good reason. Only a few years ago, Sebastian (not his real name) was locked down for 23 and a half hours every day in his prison cell, with meals brought to his door, and no sense of movement at all.“Fine Cell Work was a godsend during that time,” Sebastian tells me – as he recalls the early months of the Covid-19 outbreak. “They went above and beyond to get work to people. We really felt that somebody was looking out for us.” When Fine Cell Work (FCW) was created in 1997 by Lady Anne Tree, her idea of patronage through embroidery seemed quaint to some, perhaps even lightweight in its ethos. What could needlework possibly offer prisoners in their darkest hour? And how could stitching and sewing clear a path towards recovery and rehabilitation upon their release? Over the past 25 years, this charity has shown just how powerful a French knot can be. Since its first needlework groups were set up in HMPs Cookham Wood, Maidstone and Wandsworth, FCW has taught intricate needlework to more than 8,000 prisoners, sending volunteers into 32 prisons across the UK, with an aim to enable their apprentices to lead independent, crime-free lives.

The Cosquer cave near Marseille astonished the diver who discovered it with its ancient depictions of sea and land animals. Now it has been painstakingly recreated in the French port for all to enjoyIt was in 1985 that the diver Henri Cosquer discovered, along the coast from Marseille, what has been called an “underwater Lascaux” after the famous cave network in the Dordogne. After several failed attempts, he managed to follow a narrow tunnel, 120ft below the surface of the sea, for almost 400ft and emerged in a stunning decorated chamber. Subsequent visits revealed many images of the horses, ibexes and deer common in prehistoric cave art, but also unprecedented pictures of seals and what look very much like penguins, including one which seems to show two males competing for a watching female. This initially raised questions about authenticity, though carbon dating of the charcoal confirmed that the drawings were prehistoric. The birds were later identified not as penguins but great auks (known in French as grands pingouins), an extinct species that looks similar but is not in fact closely related.The cave came to wider public attention when three divers drowned there in 1991. It was classified as a historic monument the following year and the French state has conducted ever more precise and detailed surveys using laser scanners and high-definition photography. Portable devices can now also carry out chemical analysis, for example of pigments, on the spot. But the Cosquer cave is the only known decorated cave with an entrance under the sea, and until now it has only been accessible to very experienced divers. Global warming means that it is eventually likely to be submerged and that its amazing rock art will only be preserved virtually. It is particularly to be welcomed, therefore, that a compellingly accurate replica has now opened to the public at a prime site in Marseille, where it is hoped it will attract about 500,000 visitors a year.

There can be no one unifying theory, writes Prof Jonathan Bard, while Nicholas Maxwell looks to the role of purposive actions and Pete Bibby says the fittest theory will surviveStephen Buranyi misses some key points in his article (Do we need a new theory of evolution?, 28 June). Darwin saw novel speciation as resulting from natural selection acting on anatomical variants, but that simple skeleton needed fleshing out. It took a century of research, for example, for us to understand the importance of inheritance in very small populations if novel variants were to become predominant.The major problems in understanding evolutionary change today are as follows. First, working out how anatomical variants form – and this is hard because we don’t yet have a full understanding of how normal embryology works (evolution, it has been claimed, is development gone wrong) and can only rarely recognise a favourable mutation. Second, unpicking the generally opaque processes of selection (there are at least four independent reasons why zebra stripes would be favoured). Third, understanding why substantial evolutionary change seems so slow, albeit that this is what the fossil record demonstrates. This is the topic that excites the community that Buranyi discusses, even though modern molecular genetics and systems biology show that heritable novelties can form more rapidly than they realise.

DNA analysis of 164 individuals from 2,800 to 300 years ago shows men would move to be with their wivesThe world’s earliest seafarers who set out to colonise remote Pacific islands nearly 3,000 years ago were a matrilocal society with communities organised around the female lineage, analysis of ancient DNA suggests.The research, based on genetic sequencing of 164 ancient individuals from 2,800 to 300 years ago, suggested that some of the earliest inhabitants of islands in Oceania had population structures in which women almost always remained in their communities after marriage, while men left their mother’s community to live with that of their wife. This pattern is strikingly different from that of patrilocal societies, which appeared to be the norm in ancient populations in Europe and Africa. Continue reading...

With vaccines preventing most serious illness and death, any talk of bringing back restrictions is pure scaremongeringFour months ago, the UK took the decision to end all remaining legal Covid-19 restrictions, becoming the first major country in the world to do so. While some said it was too soon and that it would lead to a surge in cases, hospitalisations and deaths, this has thankfully not been the case. Instead, we have replaced the protection from lockdowns with the protection from science in the power of vaccines.Seeing and taking part in the incredible scenes around the UK to celebrate the Queen’s platinum jubilee just over three weeks ago showed just how far we have come in living with this virus. But even though we can rely on vaccines to protect us from severe illness or death, a virus as transmissible as Covid will not be eradicated.
