A feature that Facebook shut down in the wake of last year's Cambridge Analytica scandal came back to haunt it on Wednesday, when it emerged that hundreds of millions of Facebook users' phone numbers had been found in an unprotected online database.Millions of American Facebook users' phone numbers are believed to be among those found. Facebook said there is no evidence that any accounts were compromised. Even so, the latest discovery is a reminder that even new, stricter security policies can't necessarily address past data leaks or abuses.Until April 2018, people could enter another person's phone number to find him or her on Facebook. The company shut down the feature in the weeks after the Cambridge Analytica scandal broke because it found "malicious actors" had abused the feature to gather public information on Facebook users, a process known as scraping."Given the scale and sophistication of the activity we've seen, we believe most people on Facebook could have had their public profile scraped in this way," Mike Schroepfer, Facebook's chief technology officer, 1095

Tattoos have been around for thousands of years, primarily as an artform. But what if they had a purpose, beyond just aesthetics? “I think that we can upgrade tattoo inks to give people new abilities,” says Carson Bruns, a mechanical engineer professor at the University of Colorado. Bruns is also a tattoo aficionado. "I got my first tattoo when I was 19 years old, and I’ve been addicted to tattoos ever since," Bruns says.He spends his days in a lab, working to bring an ancient artform into the 21st Century. "My idea is that, by adding new function, new properties to the tattoo inks, that tattoos could potentially be used for more than just art," he says. Bruns is focused on a specific type of tattoo ink, one that would embed tiny microcapsules filled with certain material underneath the skin. One of his most promising developments would fill those capsules with UV dye. It’d essentially be a tattoo that tells you when you need to apply sunscreen. "So our tattoo, anytime you can see it, anytime it's visible to you, that's a sign your skin is dangerously exposed to UV light and its increasing your risk to skin cancer,” Bruns explains. Other types of inks would be heat-sensitive, like the squares he's tested on his own skin. Those would only appear when your body reached a certain temperature. "A tattooable thermometer, made of these heat sensitive tattoo inks could be a way to make it more accessible for people to read their body temp and check up on their own health," he says. Bruns says the possibilities are endless. "I like to joke tattoos can give you superpowers,” he says. “They can give our skin new properties we don't currently have."Bruns hopes that one day, we might even be able to come up with tattoo inks that could conduct electricity or even tell us our blood sugar or blood alcohol levels. 1843
