Bio-based tool quickly detects concerning coronavirus variants

Cornell researchers have developed a bioelectric device that can detect and classify new variants of coronavirus, and potentially other viruses, such as measles and influenza, to identify those that are most harmful.

'Tech neck' is a pain in more than just the neck

The typical average adult head weighs approximately 10–12 pounds. But did you know that bending it forward at a 45-degree angle to look at a cellphone or tablet can dramatically increase your chances to have "tech neck?"

Electronics

Electronics is a branch of science and technology that deals with the flow of electrons through nonmetallic conductors, mainly semiconductors such as silicon. It is distinct from electrical science and technology, which deal with the flow of electrons and other charge carriers through metal conductors such as copper. This distinction started around 1906 with the invention by Lee De Forest of the triode. Until 1950 this field was called "radio technology" because its principal application was the design and theory of radio transmitters, receivers and vacuum tubes.

The study of semiconductor devices and related technology is considered a branch of physics, whereas the design and construction of electronic circuits to solve practical problems come under electronics engineering. This article focuses on engineering aspects of electronics.
