The Invisible Force Making Food Less Nutritious

fjo3 shares a report from the Washington Post: Surging concentrations of carbon in the atmosphere, caused largely by burning fossil fuels, have produced potent changes in the way plants grow -- from increasing their sugar content to depleting essential nutrients like zinc. Experts fear the degradation of Earth's food supply will cause an epidemic of hidden hunger, in which even people who consume enough calories won't get the nutrients they need to thrive. "The diets we eat today have less nutritional density than what our grandparents ate, even if we eat exactly the same thing," said Kristie Ebi, a professor at the University of Washington's Center for Health and the Global Environment. People in wealthy countries with strong health care systems will have many tools to cope with the change, experts said. But for the world's poorest and most vulnerable, the consequences could be devastating. One study concluded that by the middle of the century the phenomenon could put more than a billion additional women and children at risk of iron-deficiency anemia -- a condition that can cause pregnancy complications, developmental problems and even death. Meanwhile, some 2 billion people across the globe who already suffer from some form of nutrient shortage could see their health problems grow even worse. "The scale of the problem is huge," Ebi said. Plants depend on carbon dioxide to perform photosynthesis -- but that doesn't mean they grow better when there's more carbon in the air, scientists say. A sweeping survey of changes among 32 compounds in 43 crops found that nearly every plant that humans eat is harmed by rising CO2 levels. [...] For the past several years, [Sterre F. ter Haar, an environmental scientist at Leiden University in the Netherlands and lead author of the survey] and her colleagues have worked to compile a database of all existing research on nutrient changes linked to rising CO2. They tracked down hundreds of studies, ranging from tightly controlled lab experiments to sprawling global analyses of real-world crops. Next the team used their dataset to calculate the nutritional densities of each crop under different carbon dioxide levels -- and to predict how their composition could continue to shift in the future. On average, they found, nutrients have already decreased by an average 3.2 percent across all plants since the late 1980s, when the concentration of carbon dioxide in the atmosphere was about 350 parts per million. That figure may seem small, ter Haar said, but with so much of the world already living on the brink of nutrient insufficiency, a drop of just a few percentage points has the potential to push millions of additional people into a health crisis. Researchers are still trying to understand the exact causes of this change. Extra CO2 can make plants grow faster and produce more carbohydrates, but without a matching increase in mineral uptake, nutrients like zinc, iron, and protein become diluted. Higher CO2 also causes plants to open their leaf pores less often, reducing the amount of water -- and dissolved minerals -- they absorb through their roots. At the same time, higher temperatures can further disrupt soil chemistry, affecting how plants take up nutrients and, in some cases, increasing their absorption of harmful substances like arsenic.

Belgium Plans To Nationalize Nuclear Power Plants

Belgium plans to buy its seven aging nuclear reactors from French power giant Engie in a "full takeover" aimed at securing domestic energy supplies, extending reactor operations, and developing new nuclear capacity. "The move would also mean suspending plans to decommission nuclear operations in Belgium," reports the BBC. From the report: The move would reverse the phase-out of nuclear energy legislation approved in the early 2000s amid safety concerns prohibiting the building of new nuclear power plants and limiting the operating lifetimes of existing ones to 40 years. Only two of Belgium's seven nuclear reactors are operational - located at plants in Doel and in Tihange - and their operating licenses were recently extended until 2035. The other five reactors were shut between 2022 and 2025 and plans to dismantle them will now be suspended. Engie and the government said they aim to reach an agreement on the takeover of the nuclear stations by October 1st. In a joint statement with Engie, the Belgian government said the move also highlights its aim to extend operations of existing nuclear reactors and to develop "new nuclear capacity" in Belgium. "By doing so, the Belgian Government is taking responsibility for Belgium's long-term energy future, with the objective of building a financially and economically viable activity that supports security of supply, climate objectives, industrial resilience and socio-economic prosperity," the statement adds.

Musk Concludes Testimony At OpenAI Trial

An anonymous reader quotes a report from CNBC: Elon Musk wrapped up his testimony on Thursday as the trial in his lawsuit against OpenAI CEO Sam Altman continued into its fourth day. OpenAI's attorney, William Savitt, cross-examined Musk in the morning. He asked Musk about the capped nature of Microsoft's investments in OpenAI, his involvement in negotiations about the company's structure, and whether he knew about the OpenAI nonprofit's recent initiatives. "I don't know what's going on at OpenAI," Musk testified. Savitt also asked Musk about his competing artificial intelligence startup, xAI. While not the main focus of the case, Musk said it is "partly" true that xAI used some of OpenAI's models to train its own models, a process known as distilling. Musk also suggested that xAI has used OpenAI's technology to help build the company. Musk sued OpenAI, Altman, and Greg Brockman, the company's president, in 2024, alleging that they went back on their commitments to keep the artificial intelligence company a nonprofit and to follow its charitable mission. He claims that the roughly $38 million he donated to seed OpenAI, a company he co-founded, was used for unauthorized commercial purposes. Once Musk wrapped up his testimony after roughly two hours of questioning on Thursday, his attorneys called Jared Birchall, who manages Musk's billions at his family office, as their next witness. Birchall testified about his knowledge of Musk's specific donations to OpenAI. Judge Yvonne Gonzalez Rogers oversaw the proceedings from federal court in Oakland, California. The trial will resume on Monday.
