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...

Vaccine-beating variant is ‘realistic possibility’, say scientists, amid calls for contingency plans to be revealed

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...

It appears unlikely, but we should try to get as close as possibleThe Office for National Statistics Covid infection survey estimates that, either through vaccination or infection, an extraordinary 94% of adults now have antibodies to Sars-CoV-2.So why are cases increasing and why does vaccine star Prof Sir Andrew Pollard say herd immunity for Covid-19 is “mythical”?

Australia’s mood has shifted from flight to fight and we’re ready to rumble. But by enlisting compassion, experts say, we can transform that rage into something more positiveShelley didn’t consider herself an angry person. Not until her friend made her a piñata for her second consecutive lockdown birthday. It was fashioned into the shape of the Covid-19 virus and painted fluoro green. She smashed it to smithereens.Now in her sixth lockdown, the Melbourne mother of two primary school kids thought she was too tired for rage, “but turns out it’s just there, simmering under the surface”.

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...

Researchers blame lack of stimulation as parents balanced childcare with working from home

Research into life of Kik adds weight to theory that climate change could have contributed to species’ demiseHe was huge, hairy and boasted two enormous tusks: researchers say they have discovered a woolly mammoth called Kik who traipsed almost far enough in his life to circle the Earth twice.Experts say the work not only sheds light on the movements of the giant proboscideans, but adds weight to ideas that climate change or human activity may have contributed to the demise of most of the creatures about 12,000 years ago.

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.

Researchers found that clots occurring after first dose of Oxford jab affected otherwise young and healthy people

Updated guidance comes after a CDC analysis of new safety data, as vaccination rates remain low among pregnant women in the USThe Centers for Disease Control (CDC) and Prevention urged all pregnant women Wednesday to get the Covid-19 vaccine as hospitals in hot spots around the US see disturbing numbers of unvaccinated mothers-to-be seriously ill with the virus.Expectant women run a higher higher risk of severe illness and pregnancy complications from the coronavirus, including perhaps miscarriages and stillbirths. But their vaccination rates are low, with only about 23% having received at least one dose, according to CDC data. Continue reading...

Road transport | Risk of death | Cricket | School notesI note that the Department for Transport spokesperson referred to special provisions for dealing with Brexit congestion as “temporary” in the announcement that the provisions are to be permanent (Report, 10 August). I am now assuming that Brexit “teething troubles” will continue for the rest of my life (like the “temporary” UK aid cut) – or until we rejoin the EU.

Pfizer reportedly asked to supply 35m more doses, with final go-ahead for this year’s programme still awaited

Critics balk at the cost of getting Britain to net zero, but the alternative is so much worseRuinous, eye-watering, crippling, stratospheric, massive. That’s the cost to the UK of beating the climate crisis, according to those who portray getting to net zero emissions as economic suicide that is being thrust on an unwilling population by posh eco-fundamentalists and zealots.This is not just wrong, it is the exact opposite of reality. The delusions come from those with histories of climate change scepticism and could be dismissed as the latest mutant variant thrown up by the death throes of denial. But they are having a real-world impact, slowing action at the precise moment acceleration is needed. Continue reading...

Exclusive: campaigners say aligning with EU ruling on chemical testing will ‘blow a hole’ in UK leadership on cruelty-free cosmeticsMinisters have opened the door to expanding the use of animal testing to ingredients used in cosmetic products for the first time in 23 years, an animal welfare charity has said.Cruelty Free International (CFI) said animal testing on ingredients exclusively used in cosmetics – which was banned in the UK in 1998 – could be required, after being told by the Home Office that the government had “reconsidered its policy.” Continue reading...

A major UN scientific report has concluded global heating is now irreversible and it is unequivocal that human influence has warmed the atmosphereA landmark UN climate report has warned that global heating is irreversible and issued its starkest warning that, unless meaningful action is taken to reduce emissions, the world is on course for catastrophic warming. The sixth Intergovernmental Panel on Climate Change report, which was published on Monday, says temperatures are likely to rise by more than 1.5C, bringing widespread extreme weather.The Guardian’s environment editor Damian Carrington tells Michael Safi that the world’s leading politicians now have nowhere to hide if they do not urgently act on the conclusions of the report. As the UK prepares to host the Cop26 climate talks in Glasgow later this year, Carrington says the path to limiting global heating to 1.5C is narrowing and commitments need to be backed with action to avert disaster.

Head of Oxford Vaccine Group rules out overall immunity, but also questions need for booster jabs

The world seems to be on the verge of collapse – yet I have just brought a baby into it“Babe, look!” my wife said excitedly, as we sprawled on the grass reading on one baking hot afternoon. She passed me her book: “Read this – this person is just like you!” I read the paragraph she was pointing to. A clearly distraught character was fulminating about poorly designed roundabouts; she kept going on and on and on about them. To be clear, I don’t have any opinions about roundabouts. Not a single one. I curtly informed my wife of this. “Yeah,” she said. “But you do have, you know, certain rants you keep coming back to. Like, incessantly.”I couldn’t argue. While I have always been a committed pessimist, recently I’ve gone into full-blown Chicken Little mode with existential obsessions. I’ll wake up, look at the latest terrifying news on my phone and immediately launch a diatribe about how we are almost certainly going to experience climate emergency-induced societal collapse in our lifetimes. “Have you seen what’s happening in Greece/northern California/Turkey?” I’ll screech. “Have you seen how many billionaires are fleeing to New Zealand to avoid the imminent apocalypse? The weather is out of control! Joe Biden and his woefully inadequate infrastructure bill aren’t going to fix anything! We are all doomed! DOOMED!” Continue reading...
