Researchers have devised an economical way of reducing the environmental impact of both the steel and aluminum industries by using hydrogen to melt down the toxic red mud left over from aluminum production to produce green steel in around 10 minutes.

An international team of IT security experts, led by the Max Planck Institute for Security and Privacy (MPI-SP) and Ruhr University Bochum, have developed a way of using radio signals to verify the location of nuclear weapon stockpiles.

Radio telescopes are picking up strange signals from an intelligent lifeform – ourselves. A new study has shown that satellite constellations like SpaceX’s Starlink swarm are unintentionally leaking signals that can interfere with vital observations.

The flapping motion of a new robotic jellyfish is not only good for propulsion, but it can also draw small bits of debris up from the ocean floor without contact. Such a robot could remove trash from delicate ocean environments, like coral reefs.

Scientists have created “acoustic holograms” that can assemble matter into 3D objects, using just sound. The technique works with various types of particles and even living cells, allowing for a new kind of 3D printing that’s fast and contact-free.

In order to spread to other host trees, the parasitic mistletoe plant has very sticky seeds that cling to bird feathers, bark, and other materials. According to a recent study, the "glue" on those seeds could inspire new biomedical adhesives.

It may seem like electronics will always get faster, but at some point the laws of physics intervene. Scientists have now calculated the absolute speed limit – the point at which quantum mechanics prevents microchips from getting any faster.

Scientists at the Joint European Torus (JET) tokamak reactor have smashed the world record for fusion plasma energy output, using the experimental device to generate 59 megajoules of energy in a landmark moment in the quest for nuclear fusion.

When leaping geckos crash head-first into vertical surfaces such as tree trunks, they're able to hang onto that surface instead of bouncing off and falling to the ground. Scientists have discovered what allows them to do so, and copied the capability in a small robot.

Physicists have confirmed a major advance in the performance of the Wendelstein 7-X fusion reactor, with efforts to address inherent energy losses in the design potentially enabling the reactor to host plasma twice as hot as the Sun's core.

Fish have a sensory system known as the lateral line, which allows them to detect movements and pressure gradients in the water. Scientists have now given a robotic fish its own version of that system, letting it determine the best swimming speed.

Using just a few hundred identical atoms, physicists at the Max Planck Institute of Quantum Optics have pieced together the world’s lightest mirror, which is invisible to the naked eye and has a surface measured in mere microns.
