Light-activated sensor delivers precision results at room temperature — ScienceDaily

Inspired by the surface of butterfly wings, researchers have developed a light-activated hydrogen sensor that produces ultra-precise results at room temperature. The technology can detect hydrogen leaks well before they pose safety risks and can measure tiny amounts of the gas on people’s breath, for diagnosing gut disorders. Commercial hydrogen sensors only work at temperatures […]

The open-source system from the 3D printer delivers high-resolution images like commercial microscopes at hundreds of times the price — ScienceDaily

Modern microscopes used for biological imaging are expensive, are located in specialized laboratories and require highly qualified staff. To research novel, creative approaches to address urgent scientific issues — for example in the fight against infectious diseases such as Covid-19 — is thus primarily reserved for scientists at well-equipped research institutions in rich countries. A […]
