PFAS “forever chemicals”—perfluoroalkyl and polyfluoroalkyl substances—are having a moment.

At the Lawrence Berkeley National Laboratory, engineers have been able to mount microcapacitors onto computer chips, which could lead to smaller electronic devices that are more energy efficient.

At a factory in Pretoria, South Africa, international food conglomerate Nestlé makes noodles and Kit Kat bars—and now, thanks to London company ECCO, it also makes baking soda and pure carbon gas.

In our most recent issue, we reported on a new process that uses catalysts and mild heat to break apart perfluoroalkyl and polyfluoroalkyl chemicals (PFAS), also called “forever” chemicals because their molecular bonds between carbon and fluorine atoms are fiendishly difficult to shatter.

Athletes, older adults, and active people in general know the problem: sooner or later, the cartilage in your knee wears out, bone rubs painfully on bone, and you think about trading it in for a plastic one. 

An air taxi that runs on pure hydrogen fuel and takes off and lands vertically set a 523-mile distance record flying over California in June, builder Joby Aviation reported. 

Ending the ability of mice to produce a protein called Interleukin 11 (IL-11) extended their lives by between 20 and 25 percent, according to research from the U.K.’s Medical Research Council Laboratory of Medical Science and Imperial College London.

Per- and polyfluoroalkyl substances make up the PFAS family of chemicals, known for their ability to remain stable when they’re wet or heated because their carbon-fluorine bonds are so strong.
