Mushroom memristors Researchers from The Ohio State University found that common edible mushrooms can be grown and trained to act as organic memristors. The team cultured samples of shiitake and button mushrooms, dehydrated them once mature to ensure long-term viability, connected them to special electronic circuits, and then electrocuted them at various voltages and frequencies. “Myce... » read more

How Photonics And Handheld Ultrasounds Are Transforming Medical Imaging
By M. Rameez Arif - 27 Oct, 2025 - Comments: 0

Medical imaging has always been a race against time: delivering accurate diagnosis to patients with the speed modern healthcare demands. Traditionally, that meant large, immobile ultrasound machines tucked away in radiology departments, often forcing patients to wait days or weeks for the imaging needed to move forward with treatment. But in recent years, the industry has been moving toward som... » read more

Can Cheaper Lasers Handle Short Distances?
By Bryon Moyer - 04 Aug, 2025 - Comments: 0

Optical technology is well established for long-haul communications, but the distances it serves are shrinking — especially in the data center. Vertical-cavity surface-emitting lasers (VCSELs) already drive short fiber links. But efforts are underway to further scale them down to provide more connections through waveguides than fiber can provide. “We have seen the transition from long... » read more
