Cases of leprosy are on the rise in Florida – should we be concerned?
The CDC reports that one-fifth of all new diagnoses in the U.S. are in the central part of the state. However, Dr Andrea Maderal, director of the University of Miami’s Hansen’s Disease Program, says there’s no need to panic. Leprosy, also known as Hansen’s Disease, is still very rare and is able to be treated with antibiotics. In fact, she says more than 95% of Americans are naturally immune to the bacteria that causes this condition (University of Miami).
How does a new battery help eliminate child labor?
Scientists have created a long-lasting battery using nickel instead of cobalt. Much of the world’s cobalt supply is often mined using child labor, but it’s always been the cheapest option – until now. A study published in the journal Nature Energy shows that these new batteries only need low amounts of nickel to power electric cars and other products (UC Irvine).
The future of robotic prosthetics is here
Research published in Nature Communications demonstrates a new robotic gripping device with game-changing abilities. It can pick up a single drop of water, and microfilms that are 20 times thinner than human hair. This gentleness and precision is complimented by strength that allows it to pick up a 14 pound weight. The gripper can be controlled through the electrical signals produced by muscles in the forearm (NC State).
