Global food supply: ‘An absolute crisis is unfolding before our eyes’

Global food supply: ‘An absolute crisis is unfolding before our eyes’

Simon Tisdall reports: Apocalypse is an alarming idea, commonly taken to denote catastrophic destruction foreshadowing the end of the world. But in the original Greek, apokálypsis means a revelation or an uncovering. One vernacular definition is “to take the lid off something”. That latter feat is exactly what Andrew Bailey, governor of the Bank of England, achieved last week, possibly inadvertently, when he suggested Britain was facing “apocalyptic” levels of food price inflation. Tory ministers fumed over what they saw…

As monkeypox goes global, scientists are on high alert

As monkeypox goes global, scientists are on high alert

Nature reports: More than 120 confirmed or suspected cases of monkeypox, a rare viral disease seldom detected outside of Africa, have been reported in at least 11 non-African countries in the past week. The emergence of the virus in separate populations across the world where it doesn’t usually appear has alarmed scientists — and sent them racing for answers. “It’s eye-opening to see this kind of spread,” says Anne Rimoin, an epidemiologist at the University of California Los Angeles, who…

The banks collapsed in 2008. Our food system is about to do the same

The banks collapsed in 2008. Our food system is about to do the same

George Monbiot writes: For the past few years, scientists have been frantically sounding an alarm that governments refuse to hear: the global food system is beginning to look like the global financial system in the run-up to 2008. While financial collapse would have been devastating to human welfare, food system collapse doesn’t bear thinking about. Yet the evidence that something is going badly wrong has been escalating rapidly. The current surge in food prices looks like the latest sign of…

What is our hidden consumption of microplastics doing to our health?

What is our hidden consumption of microplastics doing to our health?

Katharine Gammon writes: Martin Wagner was annoyed that his colleagues were always talking about microplastics in the ocean. It was 2010 and the Great Pacific Garbage Patch had been headline news. Here was this massive gyre, formed by circular ocean currents in the Pacific Ocean, reportedly brimming with plastic particles, killing sea turtles and seagulls. Wagner, a professor of biology at the Norwegian University of Science and Technology, whose lab focuses on the impact of plastics on human and ecosystem…

Study identifies outdoor air pollution as ‘largest existential threat to human and planetary health’

Study identifies outdoor air pollution as ‘largest existential threat to human and planetary health’

Inside Climate News reports: Since the turn of the century, global deaths attributable to air pollution have increased by more than half, a development that researchers say underscores the impact of pollution as the “largest existential threat to human and planetary health.” The findings, part of a study published Tuesday in The Lancet Planetary Health, found that pollution was responsible for an estimated 9 million deaths around the world in 2019. Fully half of those fatalities, 4.5 million deaths, were…

A million Covid deaths represent ‘a failure of an American ideology’

A million Covid deaths represent ‘a failure of an American ideology’

The Guardian reports: David Rosner continually talks to colleagues who are distraught about the American response to the Covid-19 pandemic. “When you are in a school of public health and a public health environment, people really feel when they are failing,” said Rosner, who studies public health and social history at the Columbia University Mailman School of Public Health. That defeated feeling is compounded by the fact that 1 million people in the US have died from Covid-19 – the…

Covid-era babies are ‘talking’ less, signaling future reading challenges

Covid-era babies are ‘talking’ less, signaling future reading challenges

Natalie Wexler reports: We know the pandemic has had a serious negative impact on the academic achievement of school-age children. But recent evidence shows we also need to worry about Covid-era babies and toddlers. Because of Covid-related disruptions, about a third of early elementary students will likely need intensive support to become proficient readers, according to one study. Now two additional studies suggest that many children born during the pandemic will also be at risk for academic failure. It seems…

Ukrainian women face harsh reality of Poland’s abortion laws

Ukrainian women face harsh reality of Poland’s abortion laws

The Guardian reports: When the first Russian bombs fell on Ukraine, Myroslava Marchenko was a gynaecologist at a private clinic in Kyiv. The next day, one of her patients was due to have an abortion after prenatal tests showed a high chance of Down’s syndrome. Instead, like millions across the country, Marchenko and her patient fled to safety, crossing the border into Poland where abortions due to foetal abnormalities – or “on eugenic grounds” in the language of the country’s…

Tiny channels discovered inside the human skull could be vital for the brain

Tiny channels discovered inside the human skull could be vital for the brain

Science Alert reports: A shortcut between the skull and the brain could be a possible way for the human immune system to bypass the blood-brain barrier. Researchers recently discovered a series of tiny channels in mice and human skulls, and in mice at least, these little pathways represent an unexpected source of brain immunity. Previously, scientists assumed that the immune system connects with the brain by slipping through a kind of neurological customs gate – a barrier separating blood channels…

‘Enforced childbirth is slavery’: Margaret Atwood on the right to abortion

‘Enforced childbirth is slavery’: Margaret Atwood on the right to abortion

Margaret Atwood writes: Nobody likes abortion, even when safe and legal. It’s not what any woman would choose for a happy time on Saturday night. But nobody likes women bleeding to death on the bathroom floor from illegal abortions either. What to do? Perhaps a different way of approaching the question would be to ask: What kind of country do you want to live in? One in which every individual is free to make decisions concerning his or her health…

Seven hours of sleep is optimal in middle and old age, say researchers

Seven hours of sleep is optimal in middle and old age, say researchers

University of Cambridge and Fudan University: Sleep plays an important role in enabling cognitive function and maintaining good psychological health. It also helps keep the brain healthy by removing waste products. As we get older, we often see alterations in our sleep patterns, including difficulty falling asleep and staying asleep, and decreased quantity and quality of sleep. It is thought that these sleep disturbances may contribute to cognitive decline and psychiatric disorders in the aging population. In research published today…

How climate change impacts pandemics

How climate change impacts pandemics

Ed Yong writes: For the world’s viruses, this is a time of unprecedented opportunity. An estimated 40,000 viruses lurk in the bodies of mammals, of which a quarter could conceivably infect humans. Most do not, because they have few chances to leap into our bodies. But those chances are growing. Earth’s changing climate is forcing animals to relocate to new habitats, in a bid to track their preferred environmental conditions. Species that have never coexisted will become neighbors, creating thousands…

China’s Covid lockdown outrage tests limits of triumphant propaganda

China’s Covid lockdown outrage tests limits of triumphant propaganda

The New York Times reports: Immediately after Beijing said it had detected a new coronavirus outbreak, officials hurried to assure residents there was no reason to panic. Food was plentiful, they said, and any lockdown measures would be smooth. But Evelyn Zheng, a freelance writer in the city, was not taking any chances. Her relatives, who lived in Shanghai, were urging her to leave or stock up on food. She had spent weeks poring over social media posts from that…

New evidence shows cancer is not as heritable as once thought

New evidence shows cancer is not as heritable as once thought

University of Alberta: While cancer is a genetic disease, the genetic component is just one piece of the puzzle — and researchers need to consider environmental and metabolic factors as well, according to a research review by a leading expert at the University of Alberta. Nearly all the theories about the causes of cancer that have emerged over the past several centuries can be sorted into three larger groups, said David Wishart, professor in the departments of biological sciences and…

Global data reveal half Covid survivors may still have symptoms four months after infection

Center for Infectious Disease Research and Policy: Worldwide, 49% of COVID-19 survivors reported persistent symptoms 4 months after diagnosis, estimates a meta-analysis of 31 studies published late last week in The Journal of Infectious Diseases. University of Michigan researchers, who conducted a systematic review on Jul 5, 2021, also found the prevalence of long COVID at 1 month at 37%, while it was 25% at 2 months and 32% at 3 months. Fifty studies were identified in the review, and…
