Scientists discover oxygen tug of war inside plant cells

Scientists have found a way to significantly boost “blue energy,” which generates electricity from the mixing of saltwater and freshwater. By coating nanopores with lipid molecules that create a friction-reducing water layer, they enabled ions to pass through much more efficiently while keeping the process highly selective. Their prototype membrane produced about two to three times more power than current technologies. The discovery could help bring osmotic energy closer to becoming a practical

DNA is revealing that many animals once thought to be a single species may actually be several hidden ones. But research on Bornean fanged frogs shows the line between species can be blurry—an important challenge when deciding what wildlife needs protection most.
