Jiaju Ma et al. of Gigajot Technology, Inc. have published a new article titled "Ultra‑high‑resolution quanta image sensor with reliable photon‑number‑resolving and high dynamic range capabilities" in Nature Scientific Reports. Abstract: Superior low‑light and high dynamic range (HDR) imaging performance with ultra‑high pixel resolution are widely sought after in the imaging world. The quanta image sensor (QIS) concept was proposed in 2005 as the next paradigm in solid‑state image sensors after charge coupled devices (CCD)and complementary metal oxide semiconductor (CMOS) active pixel sensors. This next‑generation image sensor would contain hundreds of millions to billions of small pixels with photon‑number‑resolving and HDR capabilities, providing superior imaging performance over CCD and conventional CMOS sensors. In this article, we present a 163 megapixel QIS that enables both reliable photon‑number‑resolving and high dynamic range imaging in a single device. Th

M. Lee at al. have published a paper titled "An amphibious artificial vision system with a panoramic visual field" in Nature Electronics. This paper is joint work between researchers in Korea (Institute of Basic Science, Seoul National University, Pusan National University) and USA (UT Austin and MIT). Abstract: Biological visual systems have inspired the development of various artificial visual systems including those based on human eyes (terrestrial environment), insect eyes (terrestrial environment) and fish eyes (aquatic environment). However, attempts to develop systems for both terrestrial and aquatic environments remain limited, and bioinspired electronic eyes are restricted in their maximum field of view to a hemispherical field of view (around 180°). Here we report the development of an amphibious artificial vision system with a panoramic visual field inspired by the functional and anatomical structure of the compound eyes of a fiddler crab. We integrate a microlens
