Women with Black African ancestry ‘at greater risk when plague hit London’
Experts studying remains of victims buried in 14th century say bubonic plague was not an indiscriminate killerWhen the Black Death hit London in autumn 1348, it caused a wave of devastation, with more than half the city's population thought to have been killed. But a study has now found women with Black African ancestry could have had a greater risk of death than others.Research has previously demonstrated that, far from being a homogeneous white society, medieval England - and its capital - had considerable diversity. As well as residents hailing from the far reaches of Europe, documentary and archaeological evidence has revealed people of Black African ancestry and dual heritage lived in London.

The Guardian view on the Covid inquiry: scientists and the government under the microscope | Editorial
Expanding on his startling diary entries, Sir Patrick Vallance gave crucial evidence from a unique perspectiveThe relationship between the government and scientists is under the microscope as never before. The former chief scientific adviser, Sir Patrick Vallance, gave evidence to the Covid inquiry on Monday, and Prof Chris Whitty, the chief medical officer for England, is due to take the witness stand next. Some of Sir Patrick's views are in the public domain already, due to the release of sections of his diaries. Blunt descriptions of politicians including Boris Johnson, Rishi Sunak and Matt Hancock echo those of other recent witnesses, who described Mr Johnson as incapable of leading and confused by science, Mr Sunak (then chancellor) as overly focused on the economy at the expense of health, and Mr Hancock (who was health secretary) as dishonest.Shocking details included the fact that the Scientific Advisory Group for Emergencies (Sage), which Sir Patrick chaired, did not hear anything about Mr Sunak's Eat out to help out" scheme until it was announced. On another occasion, Mr Hancock asked for evidence contained in official advice to be changed (the request was refused). Continue reading...

Don’t knock vets – we’re doing a tough job under difficult conditions | Letter
Veterinary care is expensive to provide and vets are under more pressure than ever before, says Kate Platt in response to an article by Adrian ChilesIt was with some dismay that my husband and I (both vets) read Adrian Chiles's article (What have I learned after three years of dog ownership? Beware of the vet bills, 15 November). As a practising vet for 25 years, I have never encountered a colleague who does not have the best interests of their patient first and foremost. We are trained to offer a variety of treatments at varying costs. Sadly, we do not have a crystal ball to know which dog will respond to the most basic remedies and which will require more extensive investigations and treatment.We ensure clients are fully aware of the options available and are able to make an informed decision as to which course of treatment they would like to pursue.

Scientists say mystery of how red wine headaches occur may be solved
Researchers home in on phenolic flavonoids as culprit for headaches that come on soon after a glass or twoFor the Greek philosopher Celsus, wine was the answer to endless ailments, from fatigue and fever to coughs and constipation. But despite its convenient healing powers, the grape, he conceded to his faithful readers, could bring about the odd headache.Now, researchers believe they have hit on the reason why wine - red wine, in particular - causes such swift and undeserved headaches. When the liver breaks down a particular ingredient, it produces a substance that has the same effects as a drug used to make alcoholics feel dreadful if they drink. Continue reading...
UK needs more lab space if it wants to be science superpower, ministers told

The Guardian view on new dictionary words: a parlour game that can clarify a scary reality | Editorial
AI has given us hallucination as word of the year. We should quarrel with this humanising definition while recognising that it evokes unprecedented timesWhen the Cambridge dictionary announced hallucinate" as its word of the year this week, it was not referring to its existing definition as a human condition of seeing, hearing, feeling or smelling something that does not exist", but to the phenomenon of AI developing the capacity to make - or fake - things up. This is itself a somewhat hallucinatory concept, as Naomi Klein has pointed out. Why call the errors hallucinations' at all? Why not algorithmic junk? Or glitches?" she asked. By appropriating the language of psychology, psychedelics and mysticism, she argued, the architects of generative AI had declared themselves midwives at the birth of an animate intelligence that they wanted us to believe would be an evolutionary leap for humanity.The word of the year is a strange fixture - a parlour game crossed with a marketing opportunity that is enthusiastically played by lexicographers around the world. Anyone who remembers the Oxford dictionary's choice for 2022 will know how outlandish the offspring can be: invited to make their own choice, 318,956 people - 93% of the overall vote - opted for goblin mode". Though this term (basically, slobbing out) has been around for more than a decade, its first appearance in a British newspaper, according to the research engine Factiva, was in the Observer in February last year.

Linnean Society faces eviction threat from a philistine government landlord | Letter
Huge rent increases threaten the biological society and other cherished scientific organisations based in Burlington House, writes Philip BarberThe Linnean Society of London was founded in 1788 in honour of Carl Linnaeus, the father of modern taxonomy, the system of biological classification still in use today. It is the oldest biological society still in existence, and remains a national and global flagship for natural history research. Since 1857 it has been located at Burlington House, where Charles Darwin first presented his theory of natural selection on 1 July 1858, published in the following year as The Origin of Species. The society contributes more than 8m in public value to the nation annually, but is threatened with eviction by its landlord, the housing ministry, if it fails to pay an extortionate rent which has risen by more than 3,000% in six years. Other important scientific societies at Burlington House are similarly threatened.It seems that the philistinism and cultural vandalism of a fast-fading administration are jeopardising the existence of the very institutions it should be cherishing and protecting, and we are threatened with the dismantling of a critical mass of scientific and biological expertise that can never be replaced. A new basis for tenure of one of our most valuable and durable assets needs to be urgently identified. Enough national family silver has surely now been sold off, and enough seed corn eaten, by Margaret Thatcher, George Osborne and their current political and spiritual heirs: we need to hold the line at Burlington House.
Jeremy Hunt to announce US-inspired science and technology scheme
Plan to nurture homegrown investors focused on ensuring UK innovations have commercial payoff
My brother the political prisoner, by Sanaa Seif
I was just his little sister, now I'm trying to free him from an Egyptian prisonThe drive north out of Cairo from my family home is one I know well. It's the route up to the coastal city of Alexandria, a joy-filled trip I often used to make to Egypt's north-coast beaches. On the morning of 17 November 2022, however, almost exactly a year ago today, the journey could not have felt more different. We might have been travelling in that same direction, but our destination this time was the prison where my older brother, Alaa Abd El-Fattah, is locked away. He's one of Egypt's most high-profile pro-democracy activists. A political prisoner, he's been in various jails for much of the past nine years. On the day of our visit, Alaa had spent the last six days refusing all food and water - the culmination of a 200-day partial hunger strike we'd all hoped might help secure his release. We had no idea what state we'd find him in.At 9am, my mother, aunt and I piled into a car and headed out towards the modern prison complex deep in the desert. We sat in silence - there was nothing to say. Pulling up to the compound, we all knew the drill: jump out, show officials our documents and then sit around for hours and hours. The wait that day felt especially anxious. Days previously, our family had received two short handwritten notes from Alaa, which proved he was alive. The first letter stated he was drinking water again. The second that he was eating, too, and that on our visit we should bring a birthday cake. A few days later, he'd be turning 41.

The doomsday vaults storing seeds, data and DNA to protect our future
Around the world, highly secure chambers are being built to preserve everything we need to withstand any number of worst-case scenariosAre we allowed to go in?" I surprise myself with this question, given that I'm staring through the small window of a door into one of six underground vaults, each one essentially a walk-in freezer. The temperature inside is -20C. It is a grey winter day at the Millennium Seed Bank in Wakehurst, Sussex and the maze of featureless corridors and reinforced concrete adds to the 1984-ish austerity of the setting. These vaults are designed to withstand the worst apocalypse we can imagine - be it caused by bombs, radiation, floods or disease.Dr Elinor Breman, a senior researcher, and my guide for today, briefly hesitates before responding: yes, I can, but only if I sign a waiver and don't have any heart conditions. This seems fair enough. I sign a declaration, having read the warnings of frostbite and hypothermia, and Breman hands me a protective blue coat. She flicks a switch before we go in. When I look at her quizzically, she casually explains that this is so an alarm goes off if we're not out in five minutes. Continue reading...
Rows and rockets blow up as Elon Musk’s firms endure turbulent weekend
Another space launch failed, but it's the loss of major advertisers on X that has enraged the tycoonIt has been an explosive weekend for Elon Musk. The American billionaire has had to witness not only the public rapid unscheduled disassembly" of another of his rockets, but also watch while a group of well-known global companies, including Apple, Disney and IBM, pulled advertising from X, his social media platform.The businesses, all of them household names, made the decision to stop spending on the site, formerly known as Twitter, after the American billionaire's public support for an antisemitic conspiracy theory. Last Wednesday, Musk replied to a conspiracy post which accused Jews of promoting hatred of white people, noting that it was the actual truth". He has since argued that his intended criticism was of specific campaign groups, such as the campaign group the Anti-Defamation League (ADL), and was not aimed at the wider Jewish community.

Scientists set to expose chaos and disagreement in UK government at Covid inquiry
The eat out to help out scheme will face scrutiny when Patrick Vallance, Chris Whitty and Angela McLean appear this weekExplosive evidence about the tensions and disagreements between the then prime minister Boris Johnson, his ministers and the country's top scientific advisers at key moments during the Covid-19 pandemic is expected to be made public this week at the official inquiry into the crisis. On Monday, Sir Patrick Vallance, the government's former chief scientific adviser - whose incendiary private diary entries are being quoted selectively at the inquiry - will give evidence at an all-day session on Monday that looks certain to cast new light on the chaos in government as the virus swept across the globe.Vallance will be followed in the witness box by the other top scientists who flanked ministers at the televised daily Covid press conferences.

Among the ‘memory athletes’, 1971
Could a computer ever rival their astonishing feats? The idea seemed preposterousYour memory could fill the Albert Hall,' proclaimed the Observer on 21 March 1971, explaining that a computer to perform even the simpler functions of the human brain would need to be at least as big as the Albert Hall.' Now we outsource much of our memory to devices that slip in our back pockets, what can an exploration of extraordinary memory athletes' still tell us about how we remember?Clare' (a pseudonym) discovered her abilities were exceptional while eavesdropping on a Harvard researcher exploring the power of eidetic' imagery - perfect visual recall. I think I can do that,' she said. She was right: Dr Charles Stromeyer's research showed she could scan a card with 10,000 dots for one minute and recall it a few minutes later in full detail.' Her ability to recall abstract visual patterns contrasted with the celebrated Russian mnemonist' Solomon Shereshevskii. Shereshevskii's spectacularly intense synaesthesia both helped and hindered him in constructing the elaborate mental stories he used to remember almost anything for almost any time', from Dante's Inferno to lengthy strings of random numbers.

SpaceX's Starship rocket booster explodes after blast off – video
SpaceX's spacecraft Starship, developed to carry astronauts to the moon and beyond, reached space for the first time on Saturday but was seen in footage experiencing a 'rapid unscheduled disassembly'. The two-stage rocket ship blasted off from the Elon Musk-owned company's Starbase launch site near Boca Chica in Texas on a planned 90-minute uncrewed flight into space. The 120-metre Starship rocket system, the most powerful ever built, failed a first flight test in April, when the spacecraft pulverised the launchpad during lift-off and then exploded at altitude
Kimberley Wilson: ‘You can’t have good mental health without good nutrition’
The psychologist, 40, talks about childhood memories, the shortness of life, always being honest and the answer to most of your problems: beansI was a bookish, quiet and nerdy child. I felt like an outsider, although I wonder if most kids feel that. I was rarely wild - being a black kid in east London, I was always aware of assumptions being made and of what others might get away with, but I might not.My earliest memory is having a picnic on the UK coast: sandwiches, chicken drumsticks in tinfoil and a windy car park. It's a happy one, for sure. Continue reading...
Where did they all go? How Homo sapiens became the last human species left
At least nine hominin species once roamed the Earth, so what became of our vanished ancestors?Just 300,000 years ago - a blink in evolutionary time - at least nine species of humans wandered the planet. Today, only our own, Homo sapiens, remains. And this raises one of the biggest questions in the story of human evolution: where did everyone else go?It's not a coincidence that several of them disappeared around the time that Homo sapiens started to spread out of Africa and around the rest of the world," says Prof Chris Stringer, head of human origins at the Natural History Museum in London. What we don't know is if that was a direct connection." Continue reading...

Ken Mattingly obituary
Astronaut who orbited the moon on Apollo 16 and was instrumental in saving the stricken Apollo 13The astronaut Ken Mattingly, who has died aged 87, was probably more famous for his role in the saga of Apollo 13 - the ill-fated 1970 lunar mission, from which he was removed three days before launch - than he was for Apollo 16, on which he made a successful trip to the moon two years later.Mattingly lost his place as command module pilot on Apollo 13 because he had been exposed to rubella. As a consequence he had to settle for a role within the Houston ground control team, where he helped to power up the stricken Apollo 13 spacecraft after it had broken down. Continue reading...

‘We can’t carry on’: the godfather of microplastics on how to stop them
As a UN summit in Nairobi debates a treaty on plastic pollution, Richard Thompson, the biologist who first identified microplastics 30 years ago, explains why ocean cleanups and biodegradables will not solve a global crisisIn September 1993, during a beach clean on the Isle of Man, Richard Thompson noticed thousands of multicoloured fragments at his feet, looking like sand. While his colleagues filled sacks with crisp packets, fishing rope, plastic bags and bottles, Thompson became transfixed by the particles.They were so tiny that they did not fit any category in the spreadsheet where volunteers recorded their findings. Yet it was pretty clear to me that the most abundant item on the beach was the smallest stuff," Thompson says. Continue reading...
Archaeologists uncover colourful walls and fireplaces of London workhouse

Plantwatch: restored ghost ponds bring seeds back to life
Seeds preserved for decades can be revived and the plants thrive again along with aquatic animalsPonds were once widespread on farms and rich in aquatic plants and wildlife, but long ago many were drained, filled in for intensive farming and became lost and forgotten. But these ghost ponds can be restored and the seeds of plants buried in old pond sediment can be revived after lying dormant for decades or even a century buried under fields of crops.Clues to these ghost ponds can sometimes be revealed as damp depressions on the ground, poor crop growth or from old maps. Work by University College London (UCL) showed the ponds can be resurrected by excavating them to reveal the original pond bed, then allowing rainwater or groundwater to refill them. Once exposed to light and oxygen, seeds preserved in old sediments can germinate, and in less than a year the plant life thrives again, along with aquatic animals. Continue reading...

The openness of talking to strangers – and the intimate stories they share
The stories people tell me about their lives can be funny, surprising, tragic or shocking - and some stay with me for yearsI can distinctly remember being in the back seat of the family car on a long journey (to Devon probably - that drive felt interminable), looking at all the other cars full of people and thinking, Where on earth are they all going and why?" As my eyes went funny trying to keep up with the traffic flicking past, it blew my mind to imagine everyone as the main character in the dramas of their own lives, with a busy morning behind them and a plan for the afternoon ahead. It's a thought which has never really left me. As a middle-aged woman, one of my ideas of top entertainment is to people-watch. You'll find me at it in cafes, bars, on trains. I'm completely contented when I'm losing myself in the passing tide of main characters, imagining the scenes of their lives unfurling around them. The only thing that can beat it is to take the extra step and strike up a conversation. Not the drinks party kind with all that, Did you come on the B359 or via Porchester?" The conversation with strangers I like is the bigger sort, with feelings and explanations of passions, maybe with a bit of childhood thrown in.Early on in my career as a radio reporter, this preference for the personal over the professional was obvious. I didn't make the greatest of newshounds, as I was often completely diverted by the lives which surrounded the headline. On one occasion, I was sent to interview an elderly couple on the outskirts of Peterborough. I remember their welcoming bungalow with ornaments carefully arranged on a mantel and a calendar of cat photos hanging in the kitchen. After switching off the recorder, instead of hurrying back to file my piece, I ended up chatting some more and the conversation meandered around to how the couple first met... It is a story I have never forgotten. Continue reading...
How digital twins may enable personalised health treatment
Research is growing into computational models that will move medicine beyond what works on the average patientImagine having a digital twin that gets ill, and can be experimented on to identify the best possible treatment, without you having to go near a pill or a surgeon's knife. Scientists believe that within five to 10 years, in silico" trials - in which hundreds of virtual organs are used to assess the safety and efficacy of drugs - could become routine, while patient-specific organ models could be used to personalise treatment and avoid medical complications.Digital twins are computational models of physical objects or processes, updated using data from their real-world counterparts. Within medicine, this means combining vast amounts of data about the workings of genes, proteins, cells and whole-body systems with patients' personal data to create virtual models of their organs - and eventually, potentially their entire body.

‘Violent colonialist’ Magellan is unfit to keep his place in the night sky, say astronomers
Indigenous peoples already had their own names for the galaxies named after the 16th-century Portuguese explorerFor centuries Ferdinand Magellan has been accorded a rare privilege. The explorer's name has been written in the stars. Two satellite galaxies of our own Milky Way, which sparkle conspicuously over the southern hemisphere, are labelled the Large and Small Magellanic Clouds.Now astronomers want to erase this celestial distinction. They say that Magellan, the 16th century Portuguese sailor, was a murderer who enslaved and burned down the homes of Indigenous peoples during his leadership of the first expedition to circumnavigate the globe. They insist his name should no longer be honoured by being associated with the clouds. Continue reading...
Floating factories of artificial leaves could make green fuel for jets and ships
Cambridge University scientists develop a device to defossilise' the economy using sunlight, water and carbon dioxideAutomated floating factories that manufacture green versions of petrol or diesel could soon be in operation thanks to pioneering work at the University of Cambridge. The revolutionary system would produce a net-zero fuel that would burn without creating fossil-derived emissions of carbon dioxide, say researchers.The Cambridge project is based on a floating artificial leaf which has been developed at the university and which can turn sunlight, water and carbon dioxide into synthetic fuel. The group believe these thin, flexible devices could one day be exploited on a industrial scale. Continue reading...
