To find alien life in our universe, scientists have considered searches for optical lasers or even giant energy-harvesting structures known as Dyson spheres. Now they’re suggesting a more mundane sort of search, a hunt for air pollution in exoplanet atmospheres. Source: https://earthsky.org/space/can-pollution-help-us-find-alien-life…

How the Ozone Layer Was ‘Rescued’ From a Spike in CFC
Thelasko shared this report from the BBC: A steady decline in the levels of ozone-harming CFC chemicals in the atmosphere has resumed, scientists say.

Scientists Develop Transparent Wood That Is Stronger, Lighter Than Glass
Researchers at the University of Maryland have turned ordinary sheets of wood into transparent material that is nearly as clear as glass, but stronger and with better insulating properties. It could become an energy efficient building material in the future. CBC.ca reports: Wood is made of two basic ingredients: cellulose, which are tiny fibres, and lignin, which bonds those fibres together…
