One of the most disputed issues in historical-comparative linguistics is the origin of the Japanese language and the question of whether it is related to the Transeurasian languages. MARTINE ROBBEETS has already shown in past research that it is possible to find a small core of evidence that relates Japanese as a daughter language of Transeurasian. This, she explains in this video, leads to new questions: How and why did [...] Watch video

In popular culture as in traditional archaeology, the tropical forest has been assumed to represent an environment inhospitable to humans.

In order to do so, endosomes have to have their own identity which is defined by a phosphoinositide, Phosphatidylinositol 3-phosphate (PI3P). To deliver the material to the cell surface the endosomes have to get [...] Watch video

It has been known since the 1980s that sugars are central to the growth of plants. High levels of carbohydrates enable the plant to assimilate nitrogen to increase amino acid synthesis which then enables them to make proteins more quickly which, in turn, allows the plant to grow faster. It is still unclear, however, how plants sense their levels of carbohydrates and how they regulate their metabolism and growth based on [...] Watch video

All cells in our bodies contain the same genetic information. Yet, these cells make up very different parts of the body like liver, heart, and eyes. This is achieved by expressing certain genes and inactivating others.
