PFAS: Per- and polyfluorinated alkyl substances

You can't see, smell, or taste them, but they're in our food, water, and blood: PFAS. Per- and polyfluorinated alkyl substances, invented in the 1940s, are very strong chemical compounds between carbon and fluorine. They decompose only at temperatures of up to 400 degrees Celsius or under very high pressure. They are toxic, considered carcinogenic, and found all over the world.

Laser as lightning rod

Lightning strikes can be fatal -- sending 100 million volts into the human body within 0.02 seconds, causing instant death via cardiac arrest. They kill dozens globally each year. An EU project hopes to use lasers to contain the discharges.
