Monitoring life, one breath at a time

Researchers have developed a transistor that fuses carbon nanotubes with polymers to create a capnography sensor detecting subtle changes in CO2 concentrations. This technology may provide a new tool for emergency responders to monitor patients' respiratory patterns and verify breathing tube placement.

A new twist on fiber optics

Researchers have developed spiraling glass fibers that impart a chiral character to light by polarizing photons. These fibers can be used as sensors for pressure, temperature, torque, and chemical composition, while also enabling the manipulation of polarized light in various applications.

Yet another benefit of green tea

A new, biodegradable machining compound developed by Ventana Research Corporation uses green tea extracts to improve the efficiency of computer hard drive manufacturing. The compound has shown a three- to four-fold increase in efficiency, leading to potential cost savings and environmental benefits.
