Scientists have developed the smallest microsupercapacitors to date, which can function in blood vessels and could provide an energy source for tiny sensors.
A pan-coronavirus mRNA nanoparticle vaccine with activity against all major SARS-CoV-2 variants has been described in the journal Nature, showing 100% effectiveness in macaques.
New graphene aluminium-ion cells developed by researchers in Australia are said to charge up to 70 times faster than lithium-ion cells and have triple the battery life.
Engineers have created the smallest ever single-chip system that is a complete functioning electronic circuit. This could lead to implantable chips visible only in a microscope that can be injected into the body with a hypodermic needle to monitor medical conditions.
IBM has announced the first chips based on a 2 nanometre (nm) process, allowing 50 billion transistors to be crammed onto an area the size of a fingernail, which could be arriving in 2024.
