Optics and Photonics News

  • How could we noninvasively distinguish between healthy and cancerous tissue? And how could we increase the speed of wireless communications? These two seemingly unrelated questions may share the same answer: terahertz (THz) light. Spanning frequencies between 0.3 and 20 THz, THz light interacts with matter without causing damage and allows for faster data transfer than […]
  • A new optical technique developed by researchers at the University of St Andrews and Adelaide University allows toxic methanol in alcoholic spirits to be detected without opening the bottle. Published in the Journal of Physics: Photonics, this new work offers a powerful new tool for tackling counterfeit alcohol and improving consumer safety worldwide.

Nanotechnology News

  • A newly proposed quantum sensing technique could make it much easier to identify one of physics’ newest and most intriguing classes of magnets: altermagnets. These unusual materials, discovered only a few years ago, appear to combine the speed and efficiency of antiferromagnets with some of the useful electronic properties of traditional magnets, making them promising […]
