Scientists at the University of Newcastle have discovered a way to turn the inherent randomness caused by the manufacturing of paper into a security feature, per The Economist.

The technique: Light is shined through the paper and a picture is taken with a normal digital camera. That image then has a special filter applied to it, which produces two long numbers that serve as the paper's unique "fingerprint." The whole process only takes just over a second.

A use: Instead of bulky and easily-damaged RFID chips, this technique could be used to ensure passport security around the world.

More young people are getting — and spreading — the coronavirus

More young people are being infected with the coronavirus, and even though they're less likely to die from it, experts warn the virus' spread among young adults may further fuel outbreaks across the United States.

Why it matters: Some people in their 20s and 30s face serious health complications from COVID-19, and a surge in cases among young people gives the virus a bigger foothold, increasing the risk of infection for more vulnerable people.

Joint Chiefs chairman condemns Confederate symbols

Chairman of the Joint Chiefs of Staff Gen. Mark Milley criticized Confederate symbols before the House Armed Services Committee on Thursday, and called the Civil War an "act of treason."

Why it matters: Milley said that minority service members — which he noted make up 43% of the U.S. military — may feel uncomfortable that Army bases are named for Confederate generals who "fought for an institution of slavery that may have enslaved one of their ancestors."
