Butterfly-Eyed Sensors Capture UV Images

The compound eyes of an insect are structurally very different from that of a human—almost a separate category of organ altogether from the more familiar ocular arrangement of lens, cornea, iris, and retina. For instance, Papillio xuthus, the Asian Swallowtail Butterfly, can see wavelengths of light in the ultraviolet spectrum,…

Record Broken: Decoding Words From Brain Signals

Two new brain-computer interfaces (BCI)—electronic bridges between mind and machine—decode words from people’s unspoken but intended speech. The two systems, presented in papers published this week in the journal Nature, demonstrate performance breakthroughs for speech-decoding BCI developed by scientists at Stanford University and the University of California, San Francisco.Both papers…

AI-Assisted Pathology Ready For Mainstream

Laboratory scientists and clinical pathologists currently spend hours in darkened rooms analyzing and testing tissue and fluids of patients for evidence of disease. Unlike blood tests, which are performed using automated analyzers, pathology samples are subject to time-consuming manual microscopy. Digital pathology, which uses a computer-controlled microscope to scan and…

3D Bioprinter Prints Tissue in Situ

Bioprinting is the use of 3D printing techniques to fabricate tissues out of biomaterials. It is mainly used to create human tissue for research and for drug testing in vitro. When used to create a body part intended for implantation in a patient, the part must first be printed with…
