Researchers at Northwestern University have developed a highly sensitive new tool that amplifies incredibly faint signals by 1,000 times, achieving a 50-fold improvement over previous methods.

Wang calls the instrument a Cryogenic Magneto-Terahertz Scanning Near-field Optical Microscope. (That’s cm-SNOM for short.) It’s based at the Ames National Laboratory’s Sensitive Instrument Facility ...

For Northwestern researchers operating sensitive instruments, a sudden vibration from nearby construction of the Kellogg Education Center could mean lost time and compromised data collection.

The human fingertip is an exquisitely sensitive instrument for perceiving objects in our environment via the sense of touch. A team of Chinese scientists has mimicked the underlying perceptual ...
