Ring lets users control smart devices via point and click
- A new smart ring called IRIS allows users to control smart devices by aiming the ring's camera at the device and clicking a built-in button.
- The ring sends an image of the device to the user's phone, which then controls the device through a user interface.
- In a study, twice as many users preferred IRIS over a voice command system, and it controlled home devices more than two seconds faster than voice commands on average.
- Integrating the IRIS camera system into a health-tracking smart ring could enhance human capability beyond tracking fitness metrics.

New diamond-based transistor could power the future of electronics
- Scientists from the University of Glasgow have developed a new type of diamond transistor that can deliver high power and remain off by default.
- Previous diamond transistors could either stay off well or deliver high power, but not both at the same time.
- The new transistor requires 6 volts to turn on, twice the voltage of older diamond transistors, while still delivering a strong electrical current when needed.
- Diamond transistors could be used in industries like power grids and electric vehicles, as diamond can handle high voltages better than silicon.
