One day a “magic carpet” based on this light-induced flow technology could carry climate sensors high in the atmosphere—wind permitting.

New fiber optic temperature sensing approach to keep fusion power plants running
The pursuit of fusion as a safe, carbon-free, always-on energy source has intensified in recent years, with a number of organizations pursuing aggressive timelines for technology demonstrations and power plant designs. New-generation superconducting magnets are a critical enabler for many of these programs, which creates growing need for sensors, controls, and other infrastructure that will allow the magnets to operate reliably in the harsh conditions of a commercial fusion power plant.
Researchers visualize neuron activity
A type of novel molecular voltage sensor makes it possible to watch nerve cells at work. The principle of the method has been known for some time. However, researchers at the University of Bonn and the University of California in Los Angeles have now succeeded in significantly improving it. It allows the propagation of electrical signals in living nerve cells to be observed with high temporal and spatial resolution. This enables investigations into completely new questions that were previously closed to research. The study has now been published in the journal PNAS.
Surround sound from lightweight roll-to-roll printed loudspeaker paper
If the Institute for Print and Media Technology at Chemnitz University of Technology has its way, many loudspeakers of the future will not only be as thin as paper, but will also sound impressive. This is a reality in the laboratories of the Chemnitz researchers, who back in 2015 developed the multiple award-winning T-Book—a large-format illustrated book equipped with printed electronics. If you turn a page, it begins to sound through a speaker invisibly located inside the sheet of paper. “The T-Book was and is a milestone in the development of printed electronics, but development is continuing all the time,” says Prof. Dr. Arved C. Hübler, under whose leadership this technology trend, which is becoming increasingly important worldwide, has been driven forward for more than 20 years.

David Attenborough’s grim extinction warning
Sir David Attenborough confronts viewers with some of the most shocking images of his 66-year BBC career as he outlines how animals are facing mass extinction because of humans.
Upsetting scenes in his new series A Perfect Planet, on TV in Britain now and airing on Channel 9 later this year, show a parched and psychologically damaged baby elephant – its adult relatives killed by extreme droughts – cry out as rescuers squirt water into its mouth.
A koala, its fur and paws scorched, crawls through burning undergrowth during last year’s Australian bushfires before it, too, is saved and bandaged.
This System Lets You Fly a Drone With Arm Gestures
A video uploaded by the CSAIL team shows off the system. The drone pilot is able to maneuver a small drone through a series of rings easily just by twisting, raising, and lowering his forearm thanks to a device strapped around his arm.
The goal is to make controlling the drone — and potentially other pieces of technology — as natural as possible by harnessing human intuition.
A paper published last month details the such a “plug-and-play gesture control” that relies on muscle and motion sensors.
