MHRA authorises use of vaccine on those aged 12 to 17, saying it is safe and effective for them

Extreme weather events widen existing inequalities and traumatise victims while climate anxiety affects mental healthMedical students are demanding their schools include the climate crisis as a core component of the curriculum, as the intensifying climate emergency highlights the corresponding health crisis.Hannah Chase, a final year medical student at Oxford said the sense of urgency hit home recently when a fellow student confessed they didn’t believe in climate change. “It just shows that we make such assumptions,” said Chase. “It’s needed, this education.” Continue reading...

Former slave who rose through the social ranks was interred at necropolis of Porta Sarno before AD79The partially mummified remains, including hair and bones, of a former slave who rose through the social ranks have been found in the ancient Roman city of Pompeii.The remains of Marcus Venerius Secundio were found in a tomb at the necropolis of Porta Sarno, which was one of the main entrance gates into the city. The tomb is believed to date back to the decades before Pompeii was destroyed by the eruption of Mount Vesuvius in AD79. Continue reading...

Poor policy outcomes are not the responsibility of ‘mutant maths’, but of choices made by people in powerA year ago, when the prime minister blamed a “mutant algorithm” for A-level students receiving lower than their predicted grades, a new phrase entered political discourse. Since then, the government’s proposed housing algorithm has been labelled “mutant” by the Conservative MP Philip Hollobone; recently even the pensions triple lock was referred to as a “mutant formula” by the GB News journalist Tom Harwood.It’s worth thinking about why this wording has spread. The implication of calling an algorithm “mutant” is that technology has got out of hand and that a useful mathematical system has produced perverse outcomes when applied in the real world. But this obscures the reality, which is that people in power choose when to use algorithms, set their parameters, and oversee their commissioning process. Those developing algorithms repeatedly check they are doing what ministers want them to do. When algorithms are spoken of as “mutant” it obscures this reality, framing algorithms as outside forces that act upon us, rather than tools that can help us understand the world and make decisions.

The famous number has many practical uses, mathematicians say, but is it really worth the time and effort to work out its trillions of digits?Swiss researchers have spent 108 days calculating pi to a new record accuracy of 62.8tn digits.Using a computer, their approximation beat the previous world record of 50tn decimal places, and was calculated 3.5 times as quickly. It’s an impressive and time-consuming feat that prompts the question: why? Continue reading...

Ken Wyatt blames low take-up rate partly on “choice”, while Labor blasts the rollout as a “complete failure”

Flooding, droughts and wildfires will worsen as global heating disrupts the planet’s water cycleWater problems – drought, with its accompanying wildfires, and flooding – are likely to become much worse around the world as climate breakdown takes hold, according to the biggest assessment of climate science to date.Global heating of at least 1.5C is likely to happen within the next two decades, according to the Intergovernmental Panel on Climate Change. Temperature rises will be accompanied by big changes in the planet’s water cycle, with areas that are already wet becoming much wetter, and already arid areas becoming prone to greater drought. Extreme rainfall intensifies by 7% for each additional 1C of global heating, the report found. Continue reading...

Officials have not yet established a link between the case, detected in Auckland, and the border or managed isolation facilities

The demands on parents at home in the Covid pandemic seem to only be increasing – and there’s no end in sightWeek eight of lockdown and week six of home schooling. I’m taking deep breaths before the start of this new week as last week saw me hit a new low.My five-year-old was writing the letter “h” under much duress. He is reticent at best to do his work. We would bribe him with jelly beans if he completed some of his tasks, but now even the jelly bean trick doesn’t work. Jelly beans? Pssht! He looks decidedly unimpressed. What else you got?

Fully vaccinated people no longer have to self-isolate if they are close contacts of a positive Covid case

As the climate changes, census data shows that Americans are shifting from safer areas of the US to the regions most at risk of heating and floodingScience has provided America with a decent idea of which areas of our country will be most devastated by climate change, and which areas will be most insulated from the worst effects. Unfortunately, it seems that US population flows are going in the wrong direction – new census data shows a nation moving out of the safer areas and into some of the most dangerous places of all.To quote Planes, Trains and Automobiles: we’re going the wrong way.

There’s growing evidence that signals sent from our internal organs to the brain play a major role in regulating emotions and fending off anxiety and depressionIf you’re sitting in a safe and comfortable position, close your eyes and try to feel your heart beating in your chest. Can you, without moving your hands to take your pulse, feel each movement and count its rhythm? Or do you struggle to detect anything at all? This simple test is just one way to assess your “interoception” – your brain’s perception of your body’s state, transmitted from receptors on all your internal organs.Interoception may be less well known than the “outward facing” senses such as sight, hearing, taste, touch and smell, but it has enormous consequences for your wellbeing. Scientists have shown that our sensitivity to interoceptive signals can determine our capacity to regulate our emotions, and our subsequent susceptibility to mental health problems such as anxiety and depression.

The IPCC is unequivocal: we must take urgent action to curb global heating and prevent catastrophe. Will our policymakers and the Cop26 conference be up to the task?At the end of the 60s sci-fi classic, The Day the Earth Caught Fire, the camera pans across the Daily Express case room to a front page proof hanging on a wall. “Earth Saved”, screams the headline. The camera pans. “Earth Doomed”, announces the proof beside it.The head printer looks baffled. Which page will he be told to select? We never find out, for the film concludes without revealing the fate of our planet whose rotation has been sent spiralling out of control by simultaneous Soviet and US atom bomb tests. All we know is that Earth’s fate hangs in the balance thanks to human stupidity. Continue reading...

Until relatively recently, lethal infectious diseases stalked the lives of Australian children – including my father, Tom Keneally. Vaccines have saved millionsIt’s 1940, and a five-year-old boy lies in an oxygen tent. He struggles for breath and hallucinates that his leaden toy soldiers are alive and marching around the room, monstering him with their bayonets.He has diphtheria, a disease also known as The Strangling Angel. There is a vaccine, but not every child has been inoculated. The bacterial infection creates a membrane across the back of the throat, cutting off air supply. Continue reading...

To accept the facts about climate science without changing the way we live is also to deny realityIt’s easy to laugh at the anti-vaccine movement, and this week they made it easier still. Hundreds of protesters tried to storm Television Centre in west London, apparently unaware that they were not at the headquarters of the BBC or its news operation – which they blame for brainwashing the British public – but at a building vacated by the corporation eight years ago and which now consists of luxury flats and daytime TV studios. If only they’d done their own research.Anti-vax firebreather Piers Corbyn was there, of course, unabashed by the recent undercover sting that showed him happy to take £10,000 in cash from what he thought was an AstraZeneca shareholder, while agreeing that he would exempt their product from his rhetorical fire. (Corbyn has since said that the published video is misleading.) “We’ve got to take over these bastards,” he said during this week’s protest, while inside Loose Women were discussing the menopause.

The striking thing is not the bad news, which is not really news for those who have followed the science closely. It’s the report’s insights on possibilities for cautious optimismThe first response many of us have to a cancer diagnosis is terror, horror and the conviction that we’re doomed. For those who haven’t been paying serious ongoing attention to climate chaos, reminders that we are facing catastrophe can bring the same kind of response. But if you’ve been through cancer or been close to people who have, you know that the usual next phase is figuring out what the treatment options are and, in most cases, going all out for them. The good news is going to be that you got approved for a promising new treatment, are responding well, you are in remission, feel healthier, have a good prognosis. That there are things worth doing that make a difference.Climate change is a nightmare, and this summer’s floods, fires and extreme heat, from China to Siberia to British Columbia, are reminders that the problem is rapidly growing worse. Yet the striking thing about the IPCC report released earlier this month is not the bad news, which is not really news at all for those who have followed the science closely. It’s the clarity about possibilities, which I found hopeful. Continue reading...

Young people more likely to be affected, with job losses and finances playing a possible role, say expertsMore than one in five adults said they experienced a complete breakdown in a relationship at home or at work in the past year, the UK’s largest study of social ties during the pandemic has revealed.Younger people were more likely to have their relationships affected, with experts saying it showed the disproportionate effect of the pandemic on this age group. They added that job losses and anxiety over finances could have played a role, as well as the inability to see people outside their household during the lockdown. Continue reading...

Group of scientists release draft IPCC report as they fear it will be watered down by governmentsGlobal greenhouse gas emissions must peak in the next four years, coal and gas-fired power plants must close in the next decade and lifestyle and behavioural changes will be needed to avoid climate breakdown, according to the leaked draft of a report from the world’s leading authority on climate science.Rich people in every country are overwhelmingly more responsible for global heating than the poor, with SUVs and meat-eating singled out for blame, and the high-carbon basis for future economic growth is also questioned.
