Exploring quantum systems that don't find equilibrium

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.

Water resources: Defusing conflict, promoting cooperation

Rivers are lifelines for many countries. They create valuable ecosystems, provide drinking water for people and raw water for agriculture and industry. In the Global South in particular, there is strong competition for access ...

Toxicity testing on the placenta and embryo

Researchers at ETH Zurich have developed a cell culture test to detect substances that are directly or indirectly harmful to embryos. Based on an existing test used for developing new drugs and chemicals, the augmented version ...

Optical levitation of glass nanosphere enables quantum control

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. This technique could help researchers to study quantum ...

Harnessing AI to discover new drugs inspired by nature

Artificial intelligence (AI) is able to recognize the biological activity of natural products in a targeted manner, as researchers at ETH Zurich have demonstrated. Moreover, AI helps to find molecules that have the same effect ...

A crystal made of electrons

Researchers at ETH Zurich have succeeded in observing a crystal that consists only of electrons. Such Wigner crystals were already predicted almost ninety years ago but could only now be observed directly in a semiconductor ...

Mixed cultures for a greater yield

Monocultures dominate arable land today, with vast areas given over to single elite varieties that promise a high yield. But planting arable land with just one type of crop has its disadvantages: these areas are easy game ...

Worrying insights into the chemicals in plastics

Plastic is practical, cheap and incredibly popular. Every year, more than 350 million tons are produced worldwide. These plastics contain a huge variety of chemicals that may be released during their lifecycles—including ...

Psychological understanding of the term 'artificial'

Is natural always good and artificial always bad? We talked to psychologist Angela Bearth and biotechnologist Sven Panke about science, skepticism, misunderstandings and how language influences the way we think.
