Researchers have come up with a new and improved way to levitate objects using sound waves alone, an impressive feat of mixed-reality technology that could pave the way for some seriously futuristic ...

In context: Sound waves typically propagate in forward and backward directions. This natural movement is problematic in some situations where unwanted reflections cause interference or reduced ...

In a new study, researchers demonstrated long-term, non-invasive monitoring of blood sodium levels using a system that combines optoacoustic detection with terahertz spectroscopy. Accurate measurement ...
