Most spacecraft use solar panels to power their equipment — but missions to places such as the shadowed craters of the Moon or the deep Solar System can’t rely on energy from the Sun. Could nuclear fuel, with its high energy density, be a promising alternative? In this film, Nature explores the work of a
Inside a nondescript warehouse in an industrial park in Oakville, Canada, sits a squat forklift truck that requires no driver. When activated by its remote operator, the vehicle trundles to a stack of huge clay blocks, each weighing 8,000 kilograms, and carries them into a narrow rock tunnel. Another custom-built machine then fills the spaces
Light emitted by a microplasma could be used to monitor a molten-salt nuclear reactor.Credit: ORNL New insight into an old material Because it can tolerate high temperatures and neutron damage, the carbon material graphite is used in several ways in nuclear reactors. It has a role in structural components and in fuel coatings, and it

Such images can reveal how the cancer spreads.Credit: NCI Center for Cancer Research/NCI/SPL The announcement on 19 August that people with melanoma who received a personalized vaccine lived longer without a cancer recurrence than those who didn’t have the vaccine is a sensation for the field. The results
Credit: Smithsonian Institution Archives Heisuke Hironaka, a prominent figure in algebraic geometry, was renowned for his landmark 1964 proof of the “resolution of singularities”. His work provides a way to unravel complicated phenomena in geometric objects, such as cusps, spikes and self-intersections. This fundamental result is a standard ingredient in research across a wide swathe
