It's hard to get meds to the lungs: Breathable algae offers a new path

Our lungs are fairly susceptible to diseases. Unlike most other organs, the lungs are in direct contact with the outside world. When we breathe in, our lungs can also take in things besides the oxygen we need, including irritants, ...

Magnetic 'invisibility cloak' hides obstacles within particle streams

Researchers at the University of Bayreuth have developed a method that makes objects on a magnetic field invisible within a particle stream. Until now, this so-called cloaking had only been studied for waves such as light ...
