The Northwestern and the Columbia Universities scientists have constructed a new type of a tiny laser being fully biocompatibility and able to work inside tissues of living bodies without damaging them. This 150 nm laser consumes very little energy and may become a base of new diagnostics technologies, prevention techniques and practices of healing neurological diseases etc.
Such lasers will make it possible to fight malignant cells and remove malignant tissues from nooks, inaccessible through other means. Simultaneously, they can break down toxic proteins, giving development to Alzheimer's and Parkinson's diseases.
In the process of a new nanolaser construction scientists applied the so-called photon upconversion method, which lets form a single high-energy photon by absorbing several low-energy photons. Upconversion makes low-energy infrared photons turn into visible range photons of light.
After the release of the AMD Radeon RX 5700 and 5700 XT video cards, AMD set about filling other segments of the graphics accelerator market.
AMD presents its budget-friendly notebook built on a new graphics card: The AMD company introduced its Radeon RX 5500 video cards yesterday..
