polymer n. a chemical substance consisting of large molecules made from many smaller and simpler moleculesmicroscale a. relatively small or detailed in scope or proportion
The new fiber was created by placing hundreds of square silicon microscale digital chips into a preform that was then used to create a polymer fiber.
real-time n. the actual time during which a process or event occursrespiratory a. relating to breathing or the organs of respiration
With this analytic power, the fibers someday could sense and alert people in real-time to health changes like a respiratory decline or an irregular heartbeat.
disinformation n. false information which is intended to misleadsow discord v. say and do things that cause distrust among one another
The spread of disinformation via social media has the power to change elections, strengthen conspiracy theories, and sow discord.

The team has found that by doping extra electrons into an antiferromagnetic material, they can turn its collective antialigned arrangement on and off, in a controllable way.
ferromagnet n. something having the same kind of magnetism that iron hassynchrony n. simultaneous action, development, or occurrence
Where the electrons in ferromagnets spin in synchrony - a property that allows a compass needle to point north, collectively following the Earth’s magnetic field.
