Leaked notes from Chinese health officials estimate 250 million Covid-19 infections in December

Leaked notes from Chinese health officials estimate 250 million Covid-19 infections in December

CNN reports: Almost 250 million people in China may have caught Covid-19 in the first 20 days of December, according to an internal estimate from the nation’s top health officials, Bloomberg News and the Financial Times reported Friday. If correct, the estimate – which CNN cannot independently confirm – would account for roughly 18% of China’s 1.4 billion people and represent the largest Covid-19 outbreak to date globally. The figures cited were presented during an internal meeting of China’s National…

Covid-19’s spread in China might tell us how deadly Omicron really is

Covid-19’s spread in China might tell us how deadly Omicron really is

The Wall Street Journal reports: Covid-19’s rapid spread in China has prompted reports of crowded hospitals and inundated crematoria. It could also help answer whether Omicron is truly a milder version of the virus. Iterations of the Omicron variant are spreading rapidly in China after officials relaxed zero-Covid controls in place for most of the pandemic. Pharmacies say they are out of fever medications and hospitals are strained, employees have said. Chinese officials have reported a modest rise in Covid-19…

China could see nearly a million deaths as it exits zero-Covid, study says

China could see nearly a million deaths as it exits zero-Covid, study says

CNN reports: China’s abrupt and under-prepared exit from zero-Covid could lead to nearly 1 million deaths, according to a new study, as the country braces for an unprecedented wave of infections spreading out from its biggest cities to its vast rural areas. For nearly three years, the Chinese government has used strict lockdowns, centralized quarantines, mass testing and rigorous contact tracing to curb the spread of the virus. That costly strategy was abandoned earlier this month, following an explosion of…

Life in Fukushima offers a glimpse into our contaminated future

Life in Fukushima offers a glimpse into our contaminated future

Maxime Polleri writes: As a farmer, Atsuo Tanizaki did not care much for the state’s maps of radioactive contamination. Colour-coded zoning restrictions might make sense for government workers, he told me, but ‘real’ people did not experience their environment through shades of red, orange and green. Instead, they navigated the landscape one field, one tree, one measurement at a time. ‘Case by case,’ he said, grimly, as he guided me along the narrow paths that separated his rice fields, on…

New research upends conventional wisdom about how we burn calories

New research upends conventional wisdom about how we burn calories

Herman Pontzer writes: We’re often told our metabolism speeds up at puberty and slows down in middle age, particularly with menopause, and that men have faster metabolisms than women. None of these claims is based on real science. My colleagues and I have begun to fill that gap in scientific understanding. In 2014 John Speakman, a researcher in metabolism with laboratories at the University of Aberdeen in Scotland and the Chinese Academy of Sciences in Shenzhen, organized an international effort…

Genetic legacy of Denisovans may be shaping modern immune system of southwest Pacific populations

Genetic legacy of Denisovans may be shaping modern immune system of southwest Pacific populations

Science reports: When modern humans first migrated from Africa to the tropical islands of the southwest Pacific, they encountered unfamiliar people and new pathogens. But their immune systems may have picked up some survival tricks when they mated with the locals—the mysterious Denisovans who gave them immune gene variants that might have protected the newcomers’ offspring from local diseases. Some of these variants still persist in the genomes of people living in Papua New Guinea today, according to a new…

Zero Covid’s failure is Xi’s failure

Zero Covid’s failure is Xi’s failure

Michael Schuman writes: For three years, China’s leader, Xi Jinping, fought a remorseless battle against COVID-19. He called it a “people’s war”—a national struggle to defeat an unseen foe and save lives. The contest locked families in their homes for weeks, strangled the economy, and closed the country to the world. Other governments that failed to contain the pandemic may be indifferent to death and suffering, the message was, but not the Chinese Communist Party, which cares about life above…

China scraps most Covid testing, quarantine requirements in policy shift

China scraps most Covid testing, quarantine requirements in policy shift

The Wall Street Journal reports: China dropped many of its quarantine and testing requirements and curtailed the power of local officials to shut down entire city blocks, as the government accelerates plans to dismantle zero-Covid controls in the wake of nationwide protests. The speed of Beijing’s retreat from its pandemic regime suggests the country’s leaders are now more concerned about the damage those controls have caused to China’s economy than the risk of worsening Covid infections that surged to a…

‘Forever chemicals’ may pose a bigger risk to our health than scientists thought

‘Forever chemicals’ may pose a bigger risk to our health than scientists thought

Science News reports: For decades, chemicals that make life easier — your eggs slide out of the frying pan, stains don’t stick to your sofa, rain bounces off your jackets and boots — have been touted as game changers for our busy modern lives. “Better things for better living … through chemistry,” was the optimistic slogan coined by DuPont, the company that invented the widely used chemical coating Teflon. But this better living has come at a cost that is getting…

Depressed, powerless, angry: Why frustration at China’s zero-Covid is spilling over

Depressed, powerless, angry: Why frustration at China’s zero-Covid is spilling over

The Observer reports: Victoria Li* has experienced several lockdowns since Covid emerged in China almost three years ago. Being a prisoner in her own home in Beijing made her feel depressed, powerless and angry. “Being stuck at home with my door sealed, I felt unmotivated to do anything,” she said. “I didn’t want to work, I didn’t want to study. Sometimes, I crept into my bed and cried,” said the lawyer, who is in her 20s. Even when she was…

Treating long Covid is rife with guesswork

Treating long Covid is rife with guesswork

Blake Farmer writes: Medical equipment is still strewn around the house of Rick Lucas, 62, nearly two years after he came home from the hospital. He picks up a spirometer, a device that measures lung capacity, and takes a deep breath — though not as deep as he’d like. Still, Lucas has come a long way for someone who spent more than three months on a ventilator because of Covid-19. “I’m almost normal now,” he said. “I was thrilled when…

Honeybees are living half as long as they were 50 years ago

Honeybees are living half as long as they were 50 years ago

New Scientist reports: Honeybees kept under laboratory conditions in the US only live half as long as they did in the 1970s, suggesting that genetics could be contributing to colony losses, and not just environmental factors such as pesticides and sources of food. Five decades ago, the median lifespan for a worker western honeybee (Apis mellifera) that spent its adult life in a controlled environment was 34.3 days. Now, the median is 17.7 days, according to research by Anthony Nearman…

COVID-19 origins: Investigating a ‘complex and grave situation’ inside a Wuhan lab

By Katherine Eban, Vanity Fair, and Jeff Kao, ProPublica “A Secret Language of Chinese Officialdom” Toy Reid has always had a gift for languages — one that would carry him far from what he calls his “very blue-collar” roots in Greenville, South Carolina. In high school, Spanish came easily. At nearby Furman University, where he became the first person in his family to attend college, he studied Japanese. Then, “clueless but curious,” as he puts it, he channeled his fascination…

Humans are 8% virus. How the ancient viral DNA in your genome plays a role in human disease and development

Pandemics over the course of evolution have led to the integration of viruses into our genome. Westend61via Getty Images By Aidan Burn, Tufts University Remnants of ancient viral pandemics in the form of viral DNA sequences embedded in our genomes are still active in healthy people, according to new research my colleagues and I recently published. HERVs, or human endogenous retroviruses, make up around 8% of the human genome, left behind as a result of infections that humanity’s primate ancestors…

CDC officials describe intense pressure, job threats from Trump White House, harming pandemic response

The Washington Post reports: Trump appointees oversaw a concerted effort to restrict immigration at the U.S.-Mexican border during the pandemic, change scientific reports and muzzle top officials at the Centers for Disease Control and Prevention, according to emails, text messages and interviews gathered by a congressional panel probing the pandemic response. Former CDC Director Robert Redfield, former top deputy Anne Schuchat and others described how the Trump White House and its allies repeatedly “bullied” staff, tried to rewrite their publications…

Long Covid plagues 1 in 20 people more than six months after infection

Long Covid plagues 1 in 20 people more than six months after infection

The Washington Post reports: A new long-covid study based on the experiences of nearly 100,000 participants provides powerful evidence that many people do not fully recover months after being infected with the coronavirus. The Scottish study found that between six and 18 months after infection, 1 in 20 people had not recovered and 42 percent reported partial recovery. There were some reassuring aspects to the results: People with asymptomatic infections are unlikely to suffer long-term effects, and vaccination appears to…
