Ultracold transistors serve as their own memory devices

Digital transistors—assembled by the billions in today's computer chips—act as near-perfect electronic switches. In the "on" position, achieved when an above-threshold voltage is applied to the device, the transistor ...

Controlling insulin production with a smartwatch

Many modern fitness trackers and smartwatches feature integrated LEDs. The green light emitted, whether continuous or pulsed, penetrates the skin and can be used to measure the wearer's heart rate during physical activity ...

Fundamental regulation mechanism of proteins discovered

Proteins perform a vast array of functions in the cell of every living organism with critical roles in almost every biological process. Not only do they run our metabolism, manage cellular signaling and are in charge of energy ...

Team makes single photon switch advance

The ability to turn on and off a physical process with just one photon is a fundamental building block for quantum photonic technologies. Realizing this in a chip-scale architecture is important for scalability, which amplifies ...

Photonic MEMS switches going commercial

One of the technical challenges the current data revolution faces is finding an efficient way to route the data. This task is usually performed by electronic switches, while the data itself is transferred using light confined ...

New method of artificially creating genetic switches for yeast

A group of researchers from Kobe University and Chiba University has successfully developed a flexible and simple method of artificially producing genetic switches for yeast, a model eukaryotic organism. The group consisted ...
