How robots learn to hike

“ETH Zurich researchers led by Marco Hutter developed a new control approach that enables a legged robot, called ANYmal, to move quickly and robustly over difficult terrain. Thanks to machine learning, the robot can combine its visual perception of the …

It all comes down to the first electron

“All living organisms that respire have to get rid of electrons. In oxygen-​free environments, microorganisms deploy special molecules which act as extracellular electron shuttles to transfer the electrons from cells to minerals. A group of researchers has now discovered …

Airy and efficient

“Researchers at ETH Zurich have developed a new photocatalyst made from an aerogel that could enable more efficient hydrogen production. The key is sophisticated pretreatment of the material. Aerogels are extraordinary materials that have set Guinness World Records more than …

Serious security vulnerabilities in computer memories

“Researchers at ETH Zurich have discovered major vulnerabilities in DRAM memory devices, which are widely used in computers, tablets and smartphones. The vulnerabilities have now been published together with the National Cyber Security Centre, which for the first time has …

Electrical control over designer quantum materials

“In the past few years, suitably engineered stacks of two-​dimensional materials have emerged as a powerful platform for studying quantum correlations between electronic states. ETH physicists now demonstrate how key properties of such systems can be conveniently tuned by …

An insulator made of two conductors

“At ETH Zurich researchers have observed a new state of matter: in graphene layers twisted relative to each other, two electrical conductors team up to form an insulator. Ohm’s law is well-​known from physics class. It states that …

A promising breakthrough: Nanocrystals made of amalgam

“Researchers at ETH have managed to produce nanocrystals made of two different metals using an amalgamation process whereby a liquid metal penetrates a solid one. This new and surprisingly intuitive technique makes it possible to produce a vast array of …

On eternal imbalance

“Some physical systems, especially in the quantum world, do not reach a stable equilibrium even after a long time. An ETH researcher has now found an elegant explanation for this phenomenon. If you put a bottle of beer in a …

Advancing to the core thanks to marsquakes

“Researchers at ETH Zurich and the University of Zurich have been able to use seismic data to look inside Mars for the first time. Marsquakes recorded by NASA’s InSight lander provided information about the structure of the planet’s …

Nanosphere at the quantum limit

“Researchers at ETH Zurich have trapped a tiny sphere measuring a hundred nanometres using laser light and slowed down its motion to the lowest quantum mechanical state. Based on this, one can study quantum effects in macroscopic objects and build …
