Long-term calorie restriction in diet may slow biological aging in the brain

Long-term calorie restriction in diet may slow biological aging in the brain

PsyPost reports: A new study suggests that restricting calorie intake over a lifetime may slow the biological aging of support cells in the primate brain. The research provides evidence that a thirty percent reduction in calories preserves the metabolic function of cells responsible for insulating nerve fibers. These findings were published in the journal Aging Cell. The brain relies on complex networks of communication to function correctly. This communication depends heavily on white matter, which consists of nerve fibers coated…

Study reveals the age at which you hit the ‘tipping point’ into frailty

Science Alert reports: The bumpy trajectory of human aging may have a tipping point as we enter our twilight years, a new study has found. Past the age of around 75, our bodies can no longer easily recover from injury or illness – a sharp decline in resilience that comes with a corresponding rise in the risk of dying, according to researchers at Dalhousie University in Canada. Their model looks at aging as a balance between damage and repair, with…

‘The precedent is Flint’: How Oregon’s data center boom is supercharging a water crisis

Rolling Stone reports: In the spring of 2022, Jim Doherty kept having the same conversation with folks at the only grocery store in Boardman, his eastern Oregon hometown, or at the grain depot where he picked up food for his four ranch dogs. Healthy adults that these people knew were coming down with unexplained medical conditions, including diseases and cancers that usually afflicted the elderly. “It was kinda grim,” Doherty says. Sixty years old, broad-chested, with a salt-and-pepper goatee, Doherty…

We can’t diet and exercise our way out of the next pandemic

We can’t diet and exercise our way out of the next pandemic

David Wallace-Wells writes: In the event of a sudden pandemic, what should we do? This month, Jay Bhattacharya, the director of the National Institutes of Health, offered a remarkably blunt answer: nothing. It’s been nearly six years now since the United States’ first reported cases of Covid-19, and the country is in a merciful lull when it comes to pandemic recriminations, as Robert F. Kennedy Jr.’s ongoing war on vaccine confidence now dominates the public health culture wars. But Bhattacharya,…

How the shutdown of USAID has already killed hundreds of thousands of people

  Atul Gawande writes: It was January, my final week in the outgoing Administration. In a few days, Donald Trump would be inaugurated as President. I had come to the United States Agency for International Development in early 2022, leaving my surgery practice and public-health research in Boston to lead the agency’s global-health efforts. Now I’d be returning to my previous life. I spent my last days at U.S.A.I.D. in meetings with our civil- and foreign-service leaders, thanking them. Their…

The evolving science of dietary restriction

The evolving science of dietary restriction

Andrew Steele writes: The idea that eating less might make us live longer has been around for thousands of years. Even Hippocrates, the Ancient Greek physician, argued that, “When a patient is fed too richly, the disease is fed as well. Any excess is against nature.” Scientists have now spent decades testing whether his advice holds true. The first striking evidence came in the 1930s, when American nutritionist Dr Clive McCay found that rats fed a restricted diet lived almost…

‘Access to good food should be a universal right’

Hannah Goldfield writes: One morning in late September, the writer and former Times columnist Mark Bittman walked into the Lower East Side Girls Club, a rec center in Alphabet City and the site of what would become, in less than eight hours, his first restaurant. At 6 P.M., an inaugural group of guests would arrive for the soft opening of Community Kitchen, a not-for-profit fine-dining experiment that Bittman spent years concocting, and which had found a home—for the next few…

Only 1% of people are eating a healthy and sustainable diet, major report finds

BBC Science Focus reports: A major report on the global food system has found that less than 1 per cent of the world is eating a diet that’s good for the planet and human health. But switching to a healthier eating pattern could prevent up to 15 million premature deaths per year, while cutting global greenhouse gas emissions by up to 20 per cent. These are the findings of a report by the 2025 EAT-Lancet Commission. The report brings together…

White House senses political risk on healthcare despite Trump’s shutdown bravado

The Wall Street Journal reports: President Trump has projected unwavering confidence that he is winning the messaging war over the government shutdown. But behind the scenes, his team is increasingly concerned that the issue at the center of the debate will create political vulnerabilities for Republicans. Advisers are worried that the GOP will take the blame for allowing healthcare subsidies to expire, raising costs for millions of Americans ahead of next year’s midterm elections, according to administration officials. Inside the…

Mediterranean diet may mitigate inherited risk of Alzheimer’s disease

Mediterranean diet may mitigate inherited risk of Alzheimer’s disease

PsyPost reports: A new study has revealed that a person’s genetic makeup can alter how small molecules in their blood, known as metabolites, are linked to their risk of developing dementia. The research, published in Nature Medicine, also suggests that following a Mediterranean diet may be particularly effective at lowering dementia risk for individuals who carry the highest genetic predisposition for Alzheimer’s disease. Alzheimer’s disease is a neurodegenerative condition that causes a progressive decline in memory and other cognitive abilities….

Trump’s most lethal policy: ‘People are dying every day and night’

Nicholas Kristof writes: The Trump administration has claimed that no one has died because of its cuts to humanitarian aid, and it is now trying to cancel an additional $4.9 billion in aid that Congress already approved. Yet what I find here in desperate villages in southwestern Uganda is that not only are aid cuts killing children every day, but that the death toll is accelerating. Stockpiles of food and medicine are running out here. Village health workers who used…
