Climate change poses threat to European electricity production

The vulnerability of the European electricity sector to changes in water resources is set to worsen by 2030 as a consequence of climate change. This conclusion is reached by researchers at Leiden University in an article ...

Elastic Leidenfrost effect enables soft engines

Water droplets float in a hot pan because of the so-called Leidenfrost effect. Now, physicists have discovered a variation: the elastic Leidenfrost effect. It explains why hydrogel balls jump around on a hot plate making ...

Smart design carries sound one way

A new computer simulation shows the promising possibilities of the booming field of topology. Smartly designed mechanical structures carry sound exclusively one way and are immune to fabrication errors. The study has been ...

Leiden econophysics model tested best by central banks

A full overview of all loans and debts between banks would prevent a new financial collapse. But banks do not provide this information. An econophysics model by Diego Garlaschelli and collaborators reconstructs the most probable ...

Weyl fermions exhibit paradoxical behavior

Theoretical physicists have found Weyl fermions to exhibit paradoxical behavior in contradiction to a 30-year-old fundamental theory of electromagnetism. The discovery has possible applications in spintronics. The study ...

Tiny joints for reconfigurable microstructures

Leiden physicists exploit self-assembly of small particles to someday create functional structures such as micro-robots from the bottom up. Now they took an important step forward by experimentally realizing joints on the ...

Human DNA softer than DNA single-celled life

Single-celled organisms have stiffer DNA than multicellular lifeforms like humans and rice. Theoretical physicists managed to simulate the folding in full genomes for the first time to reach this conclusion. Publication in ...

Mechanism MRI amplifying agents explored

Special amplifying agents can make MRI scanners and NMR techniques hundreds of times more sensitive. Leiden physicists have now found a method to test their efficiency. More sensitive MRI scans could for example improve our ...

Materials made of self-spinning particles

Matter is either gas, liquid or solid based on how its molecules respond to temperature and pressure. But what if the building blocks are self-spinning particles instead of ordinary molecules? Theoretical physicists found ...
