The development of the Proto-Indo-European syllabic liquids in Greek
Ancient Greek was spoken in a large number of different dialects. Although we do not find direct evidence for syllabic liquids in any of our sources, comparative evidence shows that these sounds must have been present in Proto-Greek, and that they were retained until comparatively recently in the prehistory…

Insulator becomes conductor at the push of a button
Ionic liquids are important in scientific research because they can apply a lot of charge over a surface. Leiden physicists have now found that the charging process of ionic liquids purely depends on opposite charges attracting each other. Chemical reactions are sometimes involved, but not essential.…

Happy anniversary, liquid helium
111 years ago, Heike Kamerlingh Onnis liquified helium for the first time, a tour the force that netted him the Nobel prize. It took a laboratory of a size rarely seen. Now, ultracold helium has become a commodity for physics research. In Wolfgang Löffler's lab, it is ready at hand thanks to a coffee…
