Generally speaking, women tend to work in [...] Watch video
Borders have been conceptualized in two main ways. The “static border” is the fixed line on a map that separates one country from another. Post 1989, the concept of the “disappearing border” came into fashion, the notion that borders and their influence onhuman mobility would become increasingly irrelevant. In this video, AYELET SHACHAR argues that though contemporary borders are not static, they have certainly [...] Watch video

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 this video, PATRICK ROBERTS challenges this view, demonstrating not only that Homo sapiens moved into tropical forests much earlier than previously thought but also that significant agricultural and urban societies existed in these places in the ancient past.

T cells are an important component of the body’s immune system. As ERIKA PEARCE explains, there are several types of T cells which form consecutively during the immune response and serve different purposes. Effector T cells combat pathogens from infections or tumors while memory T cells provide protective immunity to prevent re-infection or reoccurring cancer. The research presented in this video investigates how the [...] Watch video
The research presented in the video investigates how endosomes are able to transport material back to the cell surface in a process called recycling or endosomal exocytosis. 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
Multicellular organisms first took their place in the evolutionary chain some 450 million years ago.

Focusing on the freshwater polyp Hydra and employing techniques including molecular cell biology, modern sequencing technology and in depth study of stem cell behavior, Bosch argues [...] 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. The protein MOF is known to play an important role in this process: DNA does not flow freely in the cell nucleus but is packaged by histone proteins. There, MOF facilitates reading the genetic information [...] Watch video

Why and How Do Plants Emit Volatile Compounds When Defending Themselves Against Herbivores?
Plants have at least two ways of defending themselves against herbivores. They can do so directly by producing toxins or compounds that are anti-digestive, or they can indirectly defend themselves by emitting volatile compounds that attract predators and parasitoids of the herbivores. MEREDITH SCHUMANN investigates these indirect defenses. As she explains in this video, there are both fast and slow components to [...] Watch video

The researchers also [...] Watch video
Our planet’s cloudiness has been heretofore understood as being controlled by the slowly varying, large scale, atmospheric circulation known as the Hadley cell. In this video, CLAUDIA STEPHAN argues that this model is overly simplistic. Bringing recent measurements taken over the Atlantic into dialogue with observational data gathered in Darwin on gravity waves, Stephan suggests that relationships between clouds and [...] Watch video
Plants use certain chemical compounds to defend themselves against animals that feed on them. As JONATHAN GERSHENZON explains in this video, dandelions are a very good model to research the defences of plants because they are especially robust. The research team therefore investigated dandelions to identify the compound that protects the roots from being damaged by insects. They studied dandelions from different regions [...] Watch video
