Credit: Li et al., doi 10.1117/1.AP.3.2.026003 Radiation at terahertz frequencies (wavelengths between 0.03 and 0.3 mm) can be used successfully to analyze the structural dynamics of water and biomolecules. But applying the technique to aqueous solutions and tissues remains challenging, since terahertz (THz) radiation is strongly absorbed by water. While this absorption enables certain analyses, such as the structure of water and its interactions with biological solutes, it limits the thickness of samples that can be analyzed, and it drowns out weaker signals from biomolecules of interest. St...

A new process for inserting synthetic gene circuits into host cells, developed by a team of bioengineers at Arizona State University, has broad implications for improving the effectiveness of a range of disease therapies. Synthetic biology is an interdisciplinary research field that uses engineering principles to create biological components that don't exist in the natural world. These synt...
