Researchers have developed a groundbreaking method to decompose perfluoroalkyl substances (PFASs), commonly known as “forever chemicals,” using visible LED light at room temperature. This innovative approach offers a promising solution for sustainable fluorine recycling and PFAS treatment.

PFASs, widely used since the invention of Teflon in 1938, are found in various applications such as cookware, clothing, and firefighting foam. Their stability and resistance to heat and water, while useful, pose significant environmental and health challenges. These chemicals do not break down easily and accumulate in water, soil, and animal bodies, causing carcinogenic effects and hormonal disruptions in humans. Traditionally, decomposing these chemicals requires temperatures exceeding 752°F (400°C), making the process difficult and energy-intensive.

The recent discovery of a deep-sea oxygen source has stunned marine researchers and may necessitate a radical rethinking across several scientific fields, including the search for extraterrestrial life. Unlike the oxygen produced by photosynthesis, this oxygen is generated by minerals on the ocean floor.

High school science classes often teach that our oxygen comes from plant photosynthesis, particularly in tropical rainforests. However, scientists have long known that this is only partly true. While plants do produce a significant portion of the oxygen we breathe, phytoplankton in oceans and lakes contribute substantially as well. In both cases, the basic process involves living organisms using sunlight to convert carbon dioxide and water into necessary molecules, producing oxygen as a byproduct. This oxygen is crucial for sustaining life on Earth, including human life.
