Scientists at the European Space Agency used a laser to communicate with a spacecraft 165 million miles (265 million kilometers) away in deep space for the first time, marking a major step forward in their efforts to build optical communication systems for future missions to the Moon and beyond. Scientists at the Kryoneri Observatory near Athens, Greece, shot a powerful laser at NASA’s Psyche mission, which then sent a return signal to the Helmos Observatory, which lies some 23 miles (37 km) aw

Edible Microlasers Could Revolutionize Food Tracking and Safety

gizmodo.com Gayoung Lee 2025-08-10 06:00:40

In a delicious turn of events, scientists succeeded in taking the optics of olive oil to create the first-ever microlaser made entirely from edible materials. If commercialized, they could offer an easy and safe way to monitor food or medications from inside your body. The technology, introduced earlier this month in the journal Advanced Optical Materials, exploits an interesting tendency for droplets of common cooking oils, which emit a photon of light when subjected to a certain amount of ene

Before anything else, you'll have to decide between ink and laser. I'll get into the details when it comes to each model, but the most important consideration is paper type, because it’s a limitation rather than a benefit. Laser printers use heat in the bonding process, which means if you regularly print on windowed envelopes or photo paper, you'll need to either use an ink printer or change to a thermally-safe alternative, which can be cost prohibitive if you print a lot. Inkjets are the most
