New research has confirmed that the Dutch military used systematic, extreme violence against Indonesians. In his book Soldaat in Indonesië (Soldier in Indonesia), to be released at the end of October, historian Gert Oostindie draws the same conclusions using different sources. He presents new findings and explains what motivated the soldiers.
A group of scientists that includes biologists from Leiden have discovered 160 previously unknown species of plants and animals on Mount Kinabalu in Borneo. Some of these species have proved to be relatively young. The discoveries of the expedition of the Naturalis Biodiversity Center were published on 12 August in Nature.
Aqueous solutions of proteins and carbohydrates separate into two parts with an extremely ‘soft’ boundary surface. The surface tension between these two parts can be manipulated, for example by adjusting the pH balance. This can be used to develop emulsions of a water-based solution in another aqueous solution, such as fat-free mayonnaise. Leiden researchers were involved in the investigation.
