A wide range of metals need to be mined for solar panels, wind turbines and batteries. But the overall mining activity is set to decrease as clean energy replaces fossil fuels such as oil, coal and gas.

Packages of DNA strands containing silver, measuring just two or three nanometres in size. Leiden physicists Donny de Bruin and Dirk Bouwmeester create these packages, which can enter living cells on their own. They then activate the silver with light, causing the cells to break down. This could, in…

Young people tend to take more risks than children or adults. This trend is related to the reward centre in the brain, which is much more active when they are rewarded, PhD candidate Barbara Braams discovered. Personality, testosterone levels and social context also play a role in risk-taking.

Awareness of the functioning of a regional integration process and the benefits it can offer is crucial for its success, as the European Union experience has proven.

An international team of researchers observed the full extent of the evolution of hot gas produced by an active black hole for the first time. As it evolves, the hot gas encompasses a much larger area than previously thought and even impacts objects residing at great distances. Their study is published…

An Active Galactic Nucleus (AGN) is a highly luminous region at the center of a galaxy, powered by the accretion into a supermassive black hole and emitting energy from radio waves to gamma rays, often outshining the host galaxy.

Nico Staring, researcher in Egyptian art, culture and history, is taking part in the Leiden-Turin excavations in Saqqara, Egypt.
