A team from the Faculty of Physics and the Centre for Quantum Optical Technologies at the Centre of New Technologies, University of Warsaw has developed a new method for measuring elusive terahertz signals using a "quantum antenna." The authors of the work utilized a novel setup for radio wave detection with Rydberg atoms to not only detect but also precisely calibrate a so-called frequency comb in the terahertz band. This band was until recently a white spot in the electromagnetic spectrum, and the solution described in the prestigious journal Optica paves the way for ultrasensitive spectroscopy and a new generation of quantum sensors operating at room temperature.

Goldenberries taste like a cross between pineapple and mango, pack the nutritional punch of a superfood, and are increasingly popular in U.S. grocery stores. But the plants that produce these bright yellow-orange fruits grow wild and unruly—reaching heights that make large-scale farming impractical. Researchers at the Boyce Thompson Institute (BTI) helped solve that problem.

The discovery holds the potential to inspire innovations in biotechnology, from the development of new “smart” materials to nanoscale drug delivery systems.

Iron-on patches can repair clothing or add personal flair to backpacks and hats. And now they could power wearable tech, too. Researchers reporting in ACS Applied Materials & Interfaces have combined liquid metal and a heat-activated adhesive to create an electrically conductive patch that bonds to fabric when heated with a hot iron. In demonstrations, circuits ironed onto a square of fabric lit up LEDs and attached an iron-on microphone to a button-up shirt.
