Carbon nanotubes are moving from lab curiosities to workhorse components in quantum hardware, and one of the most striking examples is their use as single-photon light sources. By exploiting their ...

“Our participants created a complete lighting survey for public spaces with a total surface area of about 22 square kilometers,” Kyba says proudly. After co-developing the “Nachtlichter” app ...

The new method, which uses quantum dots, performs as well as or better than current infrared light sources while being much simpler to make. The scientists hope the breakthrough could lead to cheaper ...

Researchers at Columbia have created a chip that turns a single laser into a “frequency comb,” producing dozens of powerful light channels at once. Using a special locking mechanism to clean messy ...

Georgia MacMillan is affiliated with Dark Sky Ireland as a voluntary director (unpaid). Dark Sky Ireland is a non-profit CLG. Marie Mahon receives funding from Horizon Europe I am the Lead PI for the ...

The first piece of the Euclid space telescope's map of the universe is crammed with 14 million galaxies and 100 million sources of light. The mapping project is now 1% done. When you purchase through ...

Researchers have built a paper-thin chip that converts infrared light into visible light and directs it precisely, all without mechanical motion. The design overcomes a long-standing efficiency-versus ...
