In 2024, the Critical Raw Materials Act (CRMA) came into force. The regulation is intended to secure Europe’s supply of critical raw materials, especially minerals and metals such as lithium, cobalt, and rare earth elements. The EU is therefore focusing on reducing its dependence on third countries such as China, boosting domestic minerals and metals production, and expanding recycling. In a study published in Communications Earth & Environment, researchers at the Helmholtz Centre for Environmental Research (UFZ) show how the pursuit of security of supply has increasingly pushed sustainability principles into the background. The study also highlights how researchers can help to strengthen sustainability principles in political discourse.
Public health policies are often evaluated based on their fiscal efficiency. However, policy success also depends on evidence quality, political feasibility, implementation, and public trust. A recent analytical study introduces five dimensions of efficiency for public health policymaking and highlights how public deliberation can strengthen policy development by improving decision-making and fostering greater public trust. The findings suggest that embedding public deliberation into routine policymaking could lead to more effective and durable public health policies.
Cesare Fracassi, associate professor of finance, shows that by defining a company’s risk level, agencies can sway some of its business decisions. When Moody’s Ratings reclassified some securities on companies’ balance sheets, it prompted them to borrow an average 22% more — perhaps because they could do so without hurting their credit ratings.
“They raised more debt, and they increased their investments, even though financially, nothing really had happened to the companies,” Fracassi says.
More than 22 million Medicare patients received care from doctors born outside the United States in 2024, according to an American Board of Internal Medicine (ABIM) study published today in JAMA. A close look at internal medicine physicians—including those who continued their training to practice in subspecialty fields such as medical oncology and cardiology—revealed that doctors born abroad make up nearly half (47.2%) of the field’s workforce and provide essential care to patients in underserved communities.
A new commentary published in a special issue of the American Journal of Public Health argues that the current application process for public assistance programs such as SNAP and Medicaid creates “a lose-lose scenario," as eligible applicants often abandon the time-consuming applications out of frustration and miss out on opportunities to improve their health, which defeats the purpose of these services.
