A first-of-its-kind study in Nature finds that with bold and coordinated policy choices—across emissions, diets, food waste, and water and nitrogen efficiency—humanity could, by 2050, bring global environmental pressures back to levels seen in 2015. This shift would move us much closer to a future in which people around the world can live well within the Earth’s limits. “Our results show that it is possible to steer back toward safer limits, but only with decisive, systemic change,” says lead author Prof Detlef Van Vuuren, a researcher at Utrecht University and the Netherlands Environmental Assessment Agency (PBL).

A collaborative study from researchers affiliated with the Annenberg School for Communication, Annenberg Public Policy Center, and School of Arts & Sciences tested 17 strategies in an ‘intervention tournament.’

The United States-based National Comprehensive Cancer Network is among groups from up to 75 countries taking part in the Cancer Planners Forum in Geneva, Switzerland.

In a world where cars symbolize freedom, some Israeli families are finding liberation in going without them. A new study from the Hebrew University explores the surprising motivations of middle-class parents in Tel Aviv and Jerusalem who choose to live car-free—not out of necessity, but by design. Their reasons range from fear of driving to a desire for healthier lifestyles, stronger communities, and more independent children. These “outlier” families offer powerful insights that challenge transportation norms and open new avenues for policy and planning.

A new study published in the journal Environmental Science & Technology examined associations between diet, drinking water, and “legacy” PFAS—chemicals that were phased out of production in the US in the 2000s—with blood samples from California residents. PFAS exposure was associated with consumption of seafood, eggs, and brown rice, but fewer other foods than suggested by earlier studies. PFAS levels were elevated among people who lived in areas where these chemicals were detectable in their drinking water supply, but lower than levels found in highly contaminated communities.

Governments which impose lower taxes on heated tobacco products in the hope of encouraging smokers away from conventional cigarettes are effectively subsidising the tobacco industry, missing out on much-needed tax revenues and hampering their own public health initiatives, new research from the University of Bath shows.
