Medical physics and biotechnology: highlights of 2021

Physics World

Conventional CT requires two conversion steps to create a medical image: X-ray photons collected by a scintillator are used to generate an optical signal, which is then converted into an electrical signal. Photon counting CT, however, enables one-step conversion straight from X-ray photons into an electrical current.

Solar energy is superior to nuclear for powering crewed mission to Mars, show scientists

Frontiers

A crewed mission to Mars will require transporting equipment for creating electricity to power life support systems. Such a system can employ electricity to split water molecules to produce hydrogen, which can be stored in pressurized vessels and then re-electrified in fuel cells for power. By Peter Rejcek, science writer.
