How Did the Three-Dimensional Structures of Proteins Evolve in Nature?
See details
(Germany: Latest Thinking, 2017), 14 mins
Proteins mediate a vast array of functions in the body, like fighting invaders or transporting oxygen. Their remarkable properties are due to their three-dimensional structure which is acquired by a simple chain of molecules, a polypeptide, folding into a complex structure, the protein. This folding process is sti...

How Do Cells Form Compartments and How Is this Related to the Onset of Neurodegenerative Diseases?
See details
(Hamburg, Hamburg State: Latest Thinking, 2017), 8 mins
Molecules in cells are not randomly distributed but form compartments that perform specific functions. A few years ago, scientists discovered that many of these compartments develop by the process of phase separation which results in liquid-like compartments. This is the case for stress granules – drops formed b...

How Do Climate Change Related Natural Disasters Potentially Increase the Risk of Armed Conflicts?
See details
(Germany: Latest Thinking, 2017), 10 mins
There is an extensive discussion about the connections between climate change related disasters and armed conflicts like civil wars. JONATHAN DONGES explains in this video how the research team looked at this relationship in more detail. Their new approach connects natural disasters with large economic effects, po...

How Do Insects Use Their Sense of Smell and How Does It Function?
See details
presented by Bill S. Hansson, 1959- (Latest Thinking), 12 mins
Insects are very smell-dependent which makes them prime candidates for studying how the sense of smell works and how it influences behavior. In this video, BILL S. HANSSON describes how the research team studied the olfactory system of flies. Following the whole process from molecule detection and the reaction of...

How Do Planetary Systems Develop out of a Disk of Young Stars?
See details
(Latest Thinking, 2017), 13 mins
Over the last two decades the discovery of planets outside our solar systems has enabled researchers to study how planetary systems form - the major question within the field of astronomy today. These planetary systems and the respective planets vary significantly from each other. In order to understand how these...

How Does the Molecular Machine That Drives Energy Conversion in the Cell Membrane Work?
See details
presented by Werner Kühlbrandt, 1951- (Latest Thinking), 10 mins
Cells need to convert the energy derived from food to perform functions like muscle contractions. A “molecular machine” in the cell membrane plays a key role in this process. It works like a rotor and converts one component into another. In this video WERNER KÜHLBRANDT describes how the scientists used state-...

How Does the Presence of FLRT Proteins Influence Cortex Folding?
See details
(Latest Thinking, 2017), 13 mins
RÜDIGER KLEIN and his research group are interested in the question of how newly born cells, so-called neurons, communicate with other cells during embryonic development and how this communication shapes the brain. During development, neurons explore their environment for the presence of chemical signals. One fam...

How Does The Recycling Process Within Eukaryotic Cells Work on a Molecular Level?
See details
(Latest Thinking), 12 mins
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)....

How Is Cross-Talk Between Calcium and Actin Cytoskeleton Involved in Memory Formation?
See details
(Latest Thinking), 8 mins
How are memories formed and stored in the human brain? This is the overarching question that leads MARINA MIKHAYLOVA’s research. As she explains, there are two important features of memory formation: plasticity and stability of dendritic spines, small protrusions where synapses are formed. Activity-dependent rem...

How Is Genetic Variance Maintained Through Sexual Selection?
See details
(Hamburg, Hamburg State: Latest Thinking, 2017), 9 mins
How does sexual selection contribute to biodiversity on earth? ASTRID T. GROOT investigates this question using the example of moths. As she explains in this video, in many species, including moths, the most common individuals are chosen as mates and the ones that deviate away from the mean are selected against. F...
