Omicron’s emergence is no surprise, as richer countries’ broken promises lead to low vaccination rates – and virus mutationThe world is hostage to what’s been called “a cycle of panic and neglect”. The Omicron variant, while we wait for clarification on its many unknowns, has sparked the latest bout of that panic. But it is a panic born directly of selfish insularity: as wealthy nations have amassed enough surplus vaccines to inoculate their entire populations many times over, in low-income countries just a small percentage have received even a single dose.Even with the ambitious booster programmes, there are still plenty of unused doses sitting in the warehouses of western nations. So there’s no need to make a choice between vaccinating low-income countries or offering boosters in wealthy nations: we can still do both. New analysis from the data company Airfinity finds that, even with booster policies taken into account, in the G7 and EU there will still be close to 1.4bn surplus doses by the end of March 2022. It’s bordering on criminal that these are not being urgently airlifted to countries in need. Continue reading...

We must curb the power of Silicon Valley and protect those who speak up about the harms of AIA year ago I found out, from one of my direct reports, that I had apparently resigned. I had just been fired from Google in one of the most disrespectful ways I could imagine.Thanks to organizing done by former and current Google employees and many others, Google did not succeed in smearing my work or reputation, although they tried. My firing made headlines because of the worker organizing that has been building up in the tech world, often due to the labor of people who are already marginalized, many of whose names we do not know. Since I was fired last December, there have been many developments in tech worker organizing and whistleblowing. The most publicized of these was Frances Haugen’s testimony in Congress; echoing what Sophie Zhang, a data scientist fired from Facebook, had previously said, Haugen argued that the company prioritizes growth over all else, even when it knows the deadly consequences of doing so.Timnit Gebru is the founder and executive director of the Distributed AI Research Institute (DAIR). She was formerly co-lead of Google’s Ethical AI team Continue reading...

Nigerian high commissioner hits out as arrivals into UK face quarantine in effort to contain Omicron variant

Genetic data will soon be accessible like never before. The implications for our health are hugeWhile at the till in a clothes shop, Ruby received a call. She recognised the woman’s voice as the genetic counsellor she had recently seen, and asked if she could try again in five minutes. Ruby paid for her clothes, went to her car, and waited alone. Something about the counsellor’s voice gave away what was coming.The woman called back and said Ruby’s genetic test results had come in. She did indeed carry the mutation they had been looking for. Ruby had inherited a faulty gene from her father, the one that had caused his death aged 36 from a connective tissue disorder that affected his heart. It didn’t seem the right situation in which to receive such news but, then again, how else could it happen? The phone call lasted just a few minutes. The counsellor asked if Ruby had any questions, but she couldn’t think of anything. She rang off, called her husband and cried. The main thing she was upset about was the thought of her children being at risk. Continue reading...

Prof Dame Sarah Gilbert says this will not be the last time a virus threatens our lives and our livelihoods

Analysis: changes to cabinet and public mood from last year make further restrictions less likelyThe date ringed in red in Westminster is 18 December – not the date for Christmas parties but the time by which people should start to know how different their festive plans may look.For this government it is quite an inauspicious date, just a day before soaring cases forced Boris Johnson to finally put the brakes on Christmas mixing plans last year and tell most families they would be spending celebrations apart.

The long-running series in which readers answer other readers’ questions on subjects ranging from trivial flights of fancy to profound scientific and philosophical conceptsOn the weather forecasts, they always say: “With the wind, it’ll feel like …” How is the wind-chill factor calculated? Mick Rawlinson, BrightonSend new questions to nq@theguardian.com.Wind chill factor was designed for a limited purpose. It measures heat loss from exposed areas of the human body, like hands and face, in low temperatures and measured wind speeds. With this information, people venturing outside in exceptionally bitter weather would know an approximate time before exposed areas of the body would succumb to frostbite.

Suburbia is neither glamorous nor picturesque. But this is precisely what makes it rich terrain for my booksIt’s early December and in my corner of southeast London the Christmas illuminations are going up. Garden gnomes may have fallen out of fashion, but their seasonal equivalent, inflatable Santas, are very much in evidence. There are some pockets of tasteful conformity, where entire streets observe a “house style”, but mostly it’s a delightful free-for-all. If levels of outdoor decoration reflect a state of mind in the way that rising hemlines are said to mirror economic prosperity, then the mood here among us suburbanites is one of grim defiance.Apart from three years at university and a gap year in New Zealand, I have always lived in the suburbs, within a small triangle of southeast London – Croydon in the west, Bromley in the east and Norwood in the north. (I know that for postal purposes Croydon is Surrey, but administratively and spiritually it’s south London.) When you are a child, your own life seems normal, so it was quite some time before I realised that Croydon – fictionalised by PG Wodehouse as Mitching, “a foul hole” – had a reputation for architectural mediocrity, that the suburbs in general with their crazy-paving and curtain twitching were despised by both city and country and that having been born there was something which would need repeated apology over the years.

Staff at zoo in Belgium investigating cause of infections, which could be first reported cases in species

Caution is sensible when so much is unknownThe race is on to understand the new variant identified by scientists in South Africa and Botswana, dubbed Omicron (the next Greek letter was “nu”, but this could have been mistaken for “new”). Fears include greater spread, worse disease or reduced effectiveness of treatments and vaccines.Increased transmission can arise from two factors. First, there is an intrinsic advantage, with a heightened “basic reproduction number” R0; in a susceptible population, that is the average number of people each case infects, although after 20 months of pandemic this has become a notional concept. It was around 3 for the original wild-type virus, compared to around 6 for Delta and possibly rather more for Omicron. Continue reading...

Our planet’s geology shaped life on Earth. But now scientists reveal it worked the other way around tooThe mighty forces that created our planet’s mountains in ancient days got some unexpected help, scientists have discovered. Their research shows some of Earth’s greatest ranges got a boost from primitive lifeforms whose remains lubricated movements of rock slabs and allowed them to pile up to form mountains.If it had not been for life on Earth, the surface of our planet would have been flatter and a lot more boring, say scientists at Aberdeen and Glasgow universities where the research was carried out.

Scientists are racing to establish the variant’s transmissibility, effect on immune system and chance of hospitalisation or deathThree major issues will determine the magnitude of the impact of the new Omicron variant of the Covid virus will have on the nation and the rest of the planet. What is the transmissibility of this new Covid variant? How good is it at evading the antibodies and T-cells that make up a person’s immune defences? What are the chances it will trigger severe illness that could lead to the hospitalisation, and possibly death, of an infected person?Scientists are struggling to find definitive answers to these critically important questions, although evidence already suggests Omicron has the potential to cause serious disruption. “The situation is very finely tuned and could go in many different directions,” says Prof Rowland Kao of Edinburgh University.

Are dreams a message from the soul or meaningless ‘brain farts’? Groups dedicated to interpretation are thrivingJason DeBord regrets the demise of an old parlour game once much-loved in the 19th century: What Did I Eat Last Night? It involved a player recounting their dreams – recorded in a journal upon waking – as an audience was challenged to guess what dream-provoking food they had consumed for the previous night’s supper, be it stilton, rarebit or undercooked or cured meats (all understood to be culprits when it came to colourful dreaming).“Maybe you had eaten rare beef and then you dream about cows, you know, chasing you,” explains DeBord. “It sounds like a blast, doesn’t it? I’d have loved to have played that game.” Continue reading...

In this quasi-religious programme, ‘working the steps’ is the remedy for any problem, but for me the cracks soon started to showEight of us sat together in a circle in a wooden shed, an outbuilding at a large country house, somewhere in the south of England. The door was ajar, and spring light flooded the room. “Can anyone name any treatment methods for addiction, other than the 12 steps?” asked a counsellor.“Cognitive behavioural therapy?” offered a patient.

Study finds some pollutants are correlated with higher levels of boys and others with more girlsA swathe of pollutants and indicators of poverty have been linked to changes in the ratio of baby boys to girls born to millions of parents.A study of half the US population and the entire Swedish population examined more than 100 possible factors and found, for example, that mercury, chromium and aluminium pollution correlated with more boys being born, while lead pollution increased the proportion of girls. Proximity to farming also affected the sex ratio, possibly due to higher chemical exposures. Continue reading...

Vegan leather alternative isn’t just the hot fashion must-have – it could teach us about consumption and wasteVegan alternatives to leather could save more than just animals. The scientists behind fashion’s new latest must-have – the “mushroom leather” handbag – believe that mycelium, a material grown from fungi which can be engineered to look and feel like calfskin or sheepskin, could help save the planet.Speaking to the Guardian before a talk at the Business of Fashion Voices conference in Oxfordshire, Dr Matt Scullin, CEO of biomaterials company MycoWorks, forecast that mushroom leather could be a sustainability gamechanger, “unlocking a future of design which begins with the material, not with the object”.

Sore, blurry eyes, decaying teeth, spreading feet – the strange, difficult years of coronavirus have had unexpected effects on our general healthThis year, out of nowhere, my left heel has started hurting. Is it the onset of some degenerative condition, a normal byproduct of ageing, or simply pandemic life, I wonder. After all, living through this period has had surprising health consequences – even for people who have not caught coronavirus. It has recently emerged, for instance, that the Covid era has been a global hair-loss event – a clear manifestation of the stress everyone has been under. What else have these unprecedented times written on our bodies? Continue reading...

Clinicians around the world have noticed an increase in young adults, often women, developing ‘tic-like behaviours’ – sudden movements or vocalisations similar to what’s seen in Tourette Syndrome. Except these tics come on much later in life, and escalate more rapidly. Some have blamed the recent rise on social media – but the reality is much more complicated.Madeleine Finlay talks to Guardian reporter Sirin Kale and research psychologist Dr Seonaid Anderson about the young people experiencing this debilitating disorder, and what can be done about it.Archive: NewsNation; TikTok Continue reading...

A new Covid variant first identified in South Africa is spreading around the world, with leaders rushing to respond. Our science correspondent Nicola Davis outlines what we know so far about the Omicron variantThe identification of a new Covid variant has sent shockwaves around the world as leaders scramble once again to close borders and reintroduce measures aimed at slowing the spread of the virus. The World Health Organization has said Omicron poses a very high risk of infection. Its ability to evade Covid vaccines is of particular concern, and the chief executive of the US drugmaker Moderna has warned there is no world where the effectiveness of vaccines is at the same level as with the Delta variant.The Guardian’s science correspondent Nicola Davis tells Hannah Moore the variant is so new to scientists there is not enough data to predict how serious a threat it could pose, but the next two weeks will be crucial.

Fungi provide awe in abundance so get out there and forage in the mulch, while there’s still timeMushrooms are having a moment. Cultural depictions of fungi are proliferating: from Seana Gavin’s psychedelic mushroom collages shown at Somerset House last year; to the bestselling book Entangled Life, by the mycologist Merlin Sheldrake; we’re seeing there is more to the fungus than meets the eye. Trials into the therapeutic potential of psilocybin – derived from “magic” mushrooms – are even returning to modern medicine.And after one of the wettest summers in memory, local mushrooms are flourishing as well. Fungi-spotting reports from the public to the Royal Horticultural Society are up 76% compared with 2020, because of a bumper year.Lucy Jones is a journalist and the author of Losing Eden and The Nature Seed.
