Being levitated off the ground seems to suit human cells. Chemist Glauco Souza recently grew a bit of human lung tissue by¬†magnetically levitating¬†it in a pool of liquid full of nutrients and other chemicals that cells need to grow. The method may sound strange, but the tissue Souza and his colleagues created is among the most lifelike ever grown in lab. Their maglev setup could soon grow more true-to-life models of other types of tissues, too. In the far future, similar techniques could be used to grow implantable organs, Souza told TechNewsDaily. Souza’s lung tissue is especially sophisticated: It has…

Chemist Mingming Ma was working to make a plasticlike material for electrodes when he noticed his plastic was doing something strange. When he put a piece of it in his hand, it would curl up on itself and creep along his palm. “I put it in my own hand and I found the polymer [material] curved and it’s, like, traveling in my hand,” Ma told TechNewsDaily. “So I wanted to find out what’s the reason, what’s the mechanism of this movement?” Ma soon learned that the moisture from his skin drove the material, a film made of two different kinds…
