SuperKEKB is an electron–positron asymmetric-energy double-ring collider, which was built in Japan. It has been operated to explore new phenomena in B-meson decays. Hence, extremely higher luminosity is required. A collision scheme of low emittance

Red light is useful for optogenetic control of various protein activities in mammalian deep tissues due to its high tissue penetration, low invasiveness, and low light scattering. However, technology that enables for the optogenetic manipulation usin

Red light penetrates deep into mammalian tissues and has low phototoxicity, but few optogenetic tools that use red light have been developed. Here we present MagRed, a red light-activatable photoswitch that consists of a red light-absorbing bacterial
