New 'forever chemical' cleanup strategy discovered      (via sciencedaily.com)     Original source 

A method has been discovered to treat water heavily contaminated with unhealthful forever chemicals, known by chemists as PFAS or poly- and per-fluoroalkyl substances. It involves treating heavily contaminated water with ultraviolet (UV) light, sulfite, and a process called electrochemical oxidation. It breaks up strong fluorine-to-carbon bonds in the PFAS compounds and other concentrated organic compounds in heavily polluted water. The reaction also occurs at room temperature without a need for additional heat or high pressure. This method is expected to be useful in cleanups of PFAS pollution from decades of fire suppressant foam use at military facilities.

How climate change will affect malaria transmission      (via sciencedaily.com)     Original source 

A new model for predicting the effects of climate change on malaria transmission in Africa could lead to more targeted interventions to control the disease according to a new study. Previous methods have used rainfall totals to indicate the presence of surface water suitable for breeding mosquitoes, but the new research used several climatic and hydrological models to include real-world processes of evaporation, infiltration and flow through rivers. This groundbreaking approach has created a more in-depth picture of malaria-friendly conditions on the African continent.

Improved wildfire smoke model identifies areas for public health intervention      (via sciencedaily.com)     Original source 

The Canadian wildfires of June 2023 exposed a large portion of the Northeastern United States to unprecedented levels of smoke. A new model that combines wildfire smoke forecasts and data from ground-based sensors may help public health officials plan targeted interventions in areas most at risk for the negative health effects of unexpected smoke events and air pollution, according to scientists.

Liberals and conservatives differ on climate change beliefs -- but are relatively united in taking action      (via sciencedaily.com)     Original source 

The division between liberals and conservatives on both climate-change beliefs and related policy support is long-standing. However, the results of a newly released global experiment show that despite these differences, the two camps actually align when it comes to taking certain actions to combat climate change.

Rock steady: Study reveals new mechanism to explain how continents stabilized      (via sciencedaily.com)     Original source 

Ancient, expansive tracts of continental crust called cratons have helped keep Earth's continents stable for billions of years, even as landmasses shift, mountains rise and oceans form. A new mechanism may explain how the cratons formed some 3 billion years ago, an enduring question in the study of Earth's history.

Swarms of miniature robots clean up microplastics and microbes, simultaneously      (via sciencedaily.com)     Original source 

When old food packaging, discarded children's toys and other mismanaged plastic waste break down into microplastics, they become even harder to clean up from oceans and waterways. These tiny bits of plastic also attract bacteria, including those that cause disease. Researchers describe swarms of microscale robots (microrobots) that captured bits of plastic and bacteria from water. Afterward, the bots were decontaminated and reused.
