The climate emergency has been a wakeup call to everyone, and the ethologist and environmentalist is working as hard as ever to defeat it. She discusses horror, hope and heroism in her late 80sIn Jane Goodall’s new book, there is a vivid description of her “deep bond” with a beech tree in the garden of her childhood home in Bournemouth. She would climb into its branches to read, hauling books and her homework up in a basket, and persuaded her grandmother to bequeath her the tree, named just Beech, in her will. She called the tree, as alive to her as any person or animal, “one of my closest childhood friends”. “There’s Beech,” she says now, pointing to the handsome tree, its leaves glowing in the morning sun, from the front doorstep.The house, which first belonged to Goodall’s grandmother, is large and lovely, but modest, perhaps little changed from when Goodall lived here as a child; there are various animal feeding bowls in the living room, comfortingly cluttered, where we sit, with big windows that look out on to the garden. Her sister, Judy, and her family live here, and it’s home to Goodall when she’s not travelling the world, spreading her message of hope, and demanding action. Goodall was on her way to give a talk for Compassion in World Farming in Brussels last March, the taxi leaving the driveway, when Judy came rushing out to say it had been called off, and she has been grounded here since, mainly working from her attic bedroom.

Film crew say shooting was a ‘huge challenge’ and they had to learn to walk again after 12 days in orbitTheir movie props floated around, sleeping was difficult and they used Velcro to keep objects in place but Russia’s first film crew in space said they were delighted with the result and had “shot everything we planned”.Yulia Peresild, one of Russia’s most glamorous actors, and film director Klim Shipenko returned to Earth on Sunday after spending 12 days on the International Space Station (ISS) shooting the first movie in orbit, in an effort to beat the United States.

Reports grow of repeat infection as experts warn prevalence among school pupils puts older people at risk

Trawl of 90,000 studies finds consensus, leading to call for Facebook and Twitter to curb disinformationThe scientific consensus that humans are altering the climate has passed 99.9%, according to research that strengthens the case for global action at the Cop26 summit in Glasgow.The degree of scientific certainty about the impact of greenhouse gases is now similar to the level of agreement on evolution and plate tectonics, the authors say, based on a survey of nearly 90,000 climate-related studies. This means there is practically no doubt among experts that burning fossil fuels, such as oil, gas, coal, peat and trees, is heating the planet and causing more extreme weather. Continue reading...

Unique events that led to civilisation mean its demise could ‘eliminate meaning in galaxy for ever’Humans might be the only intelligent beings in our galaxy, so destroying our civilisation could be a galactic disaster, Prof Brian Cox has warned leaders in the run-up to Cop26.Speaking at the launch of his new BBC Two series Universe, the physicist and presenter said that having spoken to the scientists around the world advising the show, he thought that humans and sentient life on Earth “might be a remarkable, naturally occurring phenomenon” and that was something that “world leaders might need to know”.Universe starts on BBC2 on 27 October Continue reading...

Archaeological discoveries are shattering scholars’ long-held beliefs about how the earliest humans organised their societies – and hint at possibilities for our ownIn some ways, accounts of “human origins” play a similar role for us today as myth did for ancient Greeks or Polynesians. This is not to cast aspersions on the scientific rigour or value of these accounts. It is simply to observe that the two fulfil somewhat similar functions. If we think on a scale of, say, the last 3m years, there actually was a time when someone, after all, did have to light a fire, cook a meal or perform a marriage ceremony for the first time. We know these things happened. Still, we really don’t know how. It is very difficult to resist the temptation to make up stories about what might have happened: stories which necessarily reflect our own fears, desires, obsessions and concerns. As a result, such distant times can become a vast canvas for the working out of our collective fantasies.Let’s take just one example. Back in the 1980s, there was a great deal of buzz about a “mitochondrial Eve”, the putative common ancestor of our entire species. Granted, no one was claiming to have actually found the physical remains of such an ancestor, but DNA sequencing demonstrated that such an Eve must have existed, perhaps as recently as 120,000 years ago. And while no one imagined we’d ever find Eve herself, the discovery of a variety of other fossil skulls rescued from the Great Rift Valley in east Africa seemed to provide a suggestion as to what Eve might have looked like and where she might have lived. While scientists continued debating the ins and outs, popular magazines were soon carrying stories about a modern counterpart to the Garden of Eden, the original incubator of humanity, the savanna-womb that gave life to us all. Continue reading...

Last week, testing at a private Covid lab in Wolverhampton was halted, after the UK Health Security Agency found tens of thousands of people may have been falsely given a negative PCR result. But since the start of September, scientists had been alerted to strange patterns in the testing data which suggested something was out of the ordinary. Anand Jagatia speaks to Dr Kit Yates, a mathematical biologist, about why it took so long for these errors to be traced back to the lab, and what the consequences could be

Dr Jo Fayram hopes the apathy of the British public will not last; Professors Joe Sim and Steve Tombs condemn the government’s lamentable failures; Professor Patricia Deps reports on Brazil’s Covid inquiry; and Margaret Farnworth highlights a super-spreader football matchLast week the government’s response to Covid was criticised in a report by two Commons committees for apparently pursuing herd immunity by infection at the start of the pandemic. Continuing high Covid rates indicate that nothing has changed except the public’s ability to react. According to experts (Why Britons are tolerating sky-high Covid rates – and why this may not last, 15 October), a reason for this is the “normalisation” of Covid infection and deaths by the government. In reality, there is nothing normal about this “normalisation”.The UK is known as “plague island” in Europe. Surely it’s time we realised that the use of protective measures against Covid are working well across the Channel, while the UK government’s lack of action continues to lead to unnecessary illness, suffering and death. Let’s hope that the experts quoted in your article are right and that the apathy of the British public will not last.

Metre-long relic, encrusted with marine organisms, is believed to be about 900 years oldA sword believed to have belonged to a crusader who sailed to the Holy Land almost a millennium ago has been recovered from the Mediterranean seabed thanks to an eagle-eyed amateur diver, the Israel Antiquities Authority has said.Though encrusted with marine organisms, the metre-long blade, hilt and handle were distinctive enough to notice after undercurrents apparently shifted sands that had concealed it.

Two applications were made to amend poisons legislation so that the pill would not need ongoing prescriptions from doctor

At least eight types of bird flu, all of which can kill humans, are circulating around the world’s factory farms – and they could be worse than Covid-19One day last December, 101,000 chickens at a gigantic farm near the city of Astrakhan in southern Russia started to collapse and die. Tests by the state research centre showed that a relatively new strain of lethal avian flu known as H5N8 was circulating, and within days 900,000 birds at the Vladimirskaya plant were hurriedly slaughtered to prevent an epidemic.Avian flu is the world’s other ongoing pandemic and H5N8 is just one strain that has torn through thousands of chicken, duck and turkey flocks across nearly 50 countries including Britain in recent years and shows no sign of stopping.

One day a year our daughter does as she pleases and it’s always great fun… and a good education for us allWe call it her “in-charge day”. A day when our nine-year-old daughter Flora is in charge, and we are, effectively, hers to command. A day when all the traditional hierarchies between parent and child are reversed, when she can fulfil her fantasies, refuse to do anything she doesn’t want to and experience a taste of power, authority and absolute freedom.OK, not absolute freedom. There are some ground rules. She can’t do anything we deem to be unsafe or illegal. She can’t ask us to buy anything “too expensive” (we keep this part deliberately vague). And, this year, we realised we needed to add one more sentence of small print to our contract: she cannot purchase any new pets. Continue reading...

The first child born using the technique arrived last year. But can it really help reduce diseases in a new generation, or is it ‘techno-eugenics’?The birth of the first IVF baby, Louise Brown, in 1978 provoked a media frenzy. In comparison, a little girl named Aurea born by IVF in May 2020 went almost unnoticed. Yet she represents a significant first in assisted reproduction too, for the embryo from which she grew was selected from others based on polygenic screening before implantation, to optimise her health prospects.For both scientific and ethical reasons, this new type of genetic screening is highly controversial. The nonprofit California-based organisation the Center for Genetics and Society (CGS) has called its use here “a considerable reach by the assisted-reproduction industry in the direction of techno-eugenics”.

Covid has turned us into pandemic experts, all too ready to gainsay scientists and distorting our reasoning, but psychology can help us understand how our prejudices are formedAs I wasted an hour’s worth of petrol trying to find more petrol last month, Justin Webb poked at the chief secretary to the Treasury, Simon Clarke, on the Today programme, seeking a reason why much of the country is running on fumes and why HGV drivers are currently more elusive than dark matter. Clarke explained that the problem is “driven in part by workforce demographics” – no doubt – and is “worsened by Covid restrictions”. Agreed. “And worsened by Brexit,” Webb helpfully chipped in. “That’s just a fact.”But no, Clarke was having none of it. “Well, no. It’s not a fact.” Continue reading...

Life’s too short for bad literature, so let’s follow the writer’s exampleDo you ditch a book if it does not immediately grab your attention or do you trudge through it joylessly, weighed down by some invisible obligation to complete it, no matter how arduous the task? The writer Mark Billingham got stuck into this endless debate at the Cheltenham literature festival last week, admitting that he gives up on five out of 10 books that he starts, because “life’s too short” and “there are so many great books out there”. If genre fiction, in particular, doesn’t grab you after 20 pages, he said, “then, for God’s sake, throw it across the room angrily”.The thought of it! It is so bold, so cavalier. There are two books in particular that I went on to adore, after several abandoned attempts to read them. It quite literally took me years to get into both Wolf Hall and The Luminaries and it was only a combination of very lazy, pool-based holidays and dogged perseverance that finally got me to stick with them. I am very glad I did. They rewarded patience and in a culture of instant gratification this seems increasingly rare. Continue reading...

Ignorance about the basic biology of vulvas is still shockingly high – yet there are huge health benefits, physical and emotional, to be won with better understandingIf you have a vulva between your legs, could you identify the seven separate structures in a mirror? If your partner has a vulva, can you identify theirs?For over half the population, the vulva is a significant part of their body; an exit and an entrance, a site of pleasure and, often, pain, that speaks to core human function and need. In 2021, it can feel as if we’re on the cliff-edge of emancipation from the history of oppression and ick surrounding female genitalia. The booming sex toy market, a growing awareness of hormonal cycles and the messy reality of periods, a sharper focus on female pleasure and evolving conversations about menopause all point to real progress. Yet there remains a well of misunderstanding in society about what’s down there (clitoris, labia majora, labia minora, urethral opening, vaginal opening, perineum and anus, by the way), with tangible consequences.

The company employs the world’s top engineers and has access to unlimited money but is plagued by safety concerns and toxic workplace cultureThe billionaire space race is only a race by name. In actuality, there is SpaceX – and everyone else.Only the company founded by Elon Musk nearly two decades ago has sent an orbital rocket booster into space and landed it safely again. Only SpaceX has landed a rocket the size of a 15-storey building on a drone ship in the middle of the ocean. Only SpaceX has carried both Nasa astronauts and private citizens to the International Space Station. Only SpaceX is producing thousands of its own table-sized communication satellites every year. Only SpaceX has the almost weekly launch cadence necessary to single-handedly double the number of operational satellites in orbit in less than two years. Only SpaceX is launching prototypes of the largest and most powerful rocket ever made, a behemoth called Starship that is destined to carry humans to the moon. Continue reading...

Drug’s potential as Covid treatment, since dispelled, affected availability for people with proven medical need

‘I’ve never been so scared in my life,’ says Ruth Hamilton after meteorite shower above a western Canadian regionA woman in Canada awoke in shock earlier this week when a rock crashed through the ceiling of her home and landed on her bed, narrowly missing her but spraying grit and other debris on her face, as her dog barked frantically.Police were called and the culprit was initially suspected to be a construction site nearby, where work must have sent the fist-sized projectile onto the woman’s pillow. But when the construction workers said they had not set any blasts – but had just seen an explosion in the sky – the consensus quickly became that the rock was a meteorite, the Canadian Press reported.
