This Smart Bandage Can Take Your Temperature and Administer Medicine

A group of scientists at MIT have developed a futuristic hydrogel Band-Aid-like device that can incorporate a range of sensors and electronics. The versatile, programmable dressing will allow doctors to treat a range of injuries, continuously monitor a patient’s temperature and even release medicine when needed.

According to MIT, the stretchy hydrogel bandage—created by MIT professor Xuanhe Zhao and a team of graduate students—is made mostly of water and “was designed to bond strongly to surfaces such as gold, titanium, aluminum, silicon, glass, and ceramic.” The hydrogel is flexible enough that it can be applied to most body parts, including elbow and knee joints, and it can be outfitted with electronics programmed to release medicine at intervals or when a patient’s temperature rises.

“Electronics are usually hard and dry, but the human body is soft and wet. These two systems have drastically different properties,” Zhao says. “If you want to put electronics in close contact with the human body for applications such as health care monitoring and drug delivery, it is highly desirable to make the electronic devices soft and stretchable to fit the environment of the human body. That’s the motivation for stretchable hydrogel electronics.”

Afternoon Map
The Richest Person of All Time From Each State


Looking for inspiration in your quest to become a billionaire? This map from cost information website HowMuch.net, spotted by Digg, highlights the richest person in history who hails from each of the 50 states.

More billionaires live in the U.S. than in any other country, but not every state has produced a member of the Three Comma Club (seven states can only lay claim to millionaires). The map spans U.S. history, with numbers adjusted for inflation. One key finding: The group is overwhelmingly male, with only three women represented.

The richest American by far was John D. Rockefeller, repping New York with $257.25 billion to his name. Amazon's Jeff Bezos and Microsoft's Bill Gates clock in at the third and fifth richest, respectively. While today they both make their homes in the exclusive waterfront city of Medina, Washington, this map is all about birthplace. Since Gates, who is worth $90.54 billion, was born in Seattle, he wins top billing in the Evergreen State, while Albuquerque-born Bezos's $116.57 billion fortune puts New Mexico on the map.

The richest woman is South Carolina's Anita Zucker ($3.83 billion), the CEO of InterTech Group, a private, family-owned chemicals manufacturer based in Charleston. Clocking in at number 50 is the late, great socialite Brooke Astor—who, though a legend of the New York City social scene, was a native of New Hampshire—with $150 million.

There’s a Ghost Hiding in This Illustration—Can You Find It?

A hidden image illustration by Gergely Dudás, a.k.a. Dudolf

Gergely Dudás is at it again. The Hungarian illustrator, who is known to his fans as “Dudolf,” has spent the past several years delighting the internet with his hidden image illustrations, going back to the time he hid a single panda bear in a sea of snowmen in 2015. In the years since, he has played optical tricks with a variety of other figures, including sheep and Santa Claus and hearts and snails. For his latest brainteaser, which he posted to both his Facebook page and his blog, Dudolf is asking fans to find a pet ghost named Sheet in a field of white bunny rabbits.

As we’ve learned from his past creations, what makes this hidden image difficult to find is that it looks so similar to the objects surrounding it that our brains just sort of group it in as being “the same.” So you’d better concentrate.

If you’ve scanned the landscape again and again and can’t find Sheet to save your life, go ahead and click here to see where he’s hiding.
