Once a plant has germinated in a particular location, it cannot change it anymore. This means its growth depends on its location with its particular context, such as soil, herbivores, or sunlight levels. Therefore plants have evolved sophisticated signal transduction systems that allow them to perceive the outside world and then modify their growth, morphology and chemicals production and develop different phenotypes.

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 family of such chemical signals are called FLRTs. It is assumed that these FLRT proteins tell the neurons in [...] Watch video

Why are some people more prone to sickness than others? Individual people differ in their genetic predisposition to disease. TOBIAS LENZ and his research group investigate whether historical selection by pathogens – by infectious agents – has shaped the genetic makeup of our immune system today. Their specific focus here is on whether selection by pathogens on specific immune genes, so-called HLA genes, has affected [...] Watch video

One the most common types of leukemia is chronic lymphocytic leukemia. To find the right treatment for an individual patient with that disease is a challenging task and many patients develop a resistance against the existing drugs. The purpose of the research presented by BRIGITTE VOIT in this video is to find new drugs that reduce cancer cells while not destroying other cells in the body. The researchers created two [...] Watch video

Our immune system has evolved many different cells with different functions to prevent infections. One of these functions is cellular cytotoxicity; this means that cells are able to kill other cells. Natural killer cells (NK cells) are one type of these cells that can achieve cytotoxicity. CARSTEN WATZL experiments with NK cells in order to find out how they protect themselves from their own cytotoxic machinery and how [...] Watch video

During the evolution of primates their brain size, and specifically the size of their cerebral cortex where the higher cognitive functions are located, expanded. Stem cells in the human brain go through a higher number of cell divisions and thus produce a higher number of neurons then do stem cells in the brains of apes. The research presented in this video investigates which evolutionary changes in the genome caused this [...] Watch video

The technique of Magnetic Resonance Imaging, or short MRI, is a useful and widely used tool in clinical diagnostics. However, the current MRI techniques are not sensitive enough to detect low concentrations of drugs or disease related molecules. LEIF SCHRÖDER explains that MRI is typically based on the detection of water molecules. However, the high water concentration that is always present in the body creates a strong [...] Watch video

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. Following this principle, you would expect less and less variation but this is not the case. Thus, her research [...] Watch video

The connective tissues in our body – such as skin, tendon, or bones – all contain a molecule called collagen. When you cut your skin, it springs open. This shows that the tissues in our body are under pretension. The research presented in this video is interested in the question of whether the interaction of collagen with water causes this tension. The researchers found, as PETER FRATZL explains, that the pretension [...] Watch video

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

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 still not fully understood and hence also difficult to replicate in a laboratory. To learn more about how it [...] 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

The gut microbiome has a significant influence on various diseases ranging from malnutrition to chronic inflammation. It is largely shaped by environmental factors, like diet and lifestyle. How the genetics of the individual affect the composition of the microbiome, however, was largely unknown.

Instead, they restrain themselves and employ proportionality as an instrument of rationality review, i.e. [...] Watch video

One hour of sunlight is enough to power the entire planet for over a year. MICHAEL SALIBA is a leading scientist who investigates how we can tap into this abundant energy source in order to produce sustainable electricity in the future. As he explains in this video, the perovskite semiconductor – a new material that was discovered about five years ago – has great potential to advance the use of solar energy. The [...] Watch video

In the modern world, computer applications operate in an environment of increasing complexity. Ubiquitously connected, they rely on continuously changing interfaces with the external world to drive computations based on patterns in big data. In this video, MIRA MEZINI considers how programming technology can optimally respond to this radically changed operating environment. Arguing that accidental complexity can be [...] Watch video

Exoplanets are planets beyond our own solar system. Since they do not emit much light and moreover are very close to their parent stars they are difficult to detect directly. When searching for exoplanets, astronomers use telescopes to monitor the brightness of the parent star under investigation: Changes in brightness can point to a passing planet that obstructs part of the star’s surface. The recorded signal, however, [...] Watch video

In the 1980s researchers showed that damaged nerves in the spinal cord have the ability to regrow. Chemical engineers contribute to the field of spinal cord repair by developing biomaterial scaffolds that support cell and nerve growth inside the body after an injury. In the research project explained by LAURA DE LAPORTE in this video, such scaffolds were developed and tested: The special architecture of the developed [...] Watch video

The silicon-based technology that is used today to access and compute information is reaching its limits. To further improve computing capacity, this essentially two-dimensional technology, as STUART PARKIN puts it, needs to give way to the three-dimensional approach of spintronic devices that use not only electric current but also the spin of the electrons. In this video, he explains how the research team created a new [...] Watch video

Many android apps that try to use SSL to secure network communication fail in doing so and are insecure. By detecting such security flaws and interviewing the developers, the study presented in this video shows the necessity of rethinking how developers interact with security code. As shown, developers are not, as often implied, infallible. This means that prevention of security problems should be carried out by [...] Watch video

Aesthetic experiences make a vital contribution to our lives. In this video, focusing on responses to artwork, architecture and natural landscapes, EDWARD VESSEL explores how aesthetic experiences function in the brain. Employing functional Magnetic Resonance Imaging (fMRI), Vessel attempts to correlate subjects’ aesthetic responses with data from two brain regions, the ventral occipitotemporal cortex and the default [...] Watch video

How do humans understand each other? One unique aspect is the evolution of more than six thousand languages on earth. In order to use language meaningfully a certain social cognitive infrastructure is needed. This infrastructure turns out to be prior to the acquisition of language in humans. The research presented in this video investigates how infants learn to communicate and how they understand other people’s [...] Watch video

Our society is becoming more and more diverse concerning cultural, linguistic, ethnic and religious aspects. Therefore, children growing up in a pluralistic society need intercultural competence as a key skill. Schools are a prominent place where children can acquire this competence and some studies suggest that physical education is a particularly adept subject to transmit intercultural competence because it combines [...] Watch video

With unprecedented acceleration in the geophysical impact of human activities and the identification of “tipping points” from which our planet will not be able to recover, mankind faces an increasingly imminent existential threat. In this video, STEFAN BRUNNHUBER describes how insights from psychology could help human beings to overcome these challenges. Brunnhuber demonstrates that existing proposed solutions, [...] Watch video

Allegiance to a particular form of therapy or financial ties to a pharmaceutical company are among the phenomena that can undermine a physician’s primary goal, to provide the best possible treatment for his or her patients. In this video, KLAUS LIEB explores the ways in which conflicts of interest occur for both physicians and medical researchers before providing some suggestions as to how they might be avoided.

Using survey data and combining multilevel modelling with propensity score matching the study presented in this video examines the effects of social networks among parents on their children’s educational attainment in different social environments. The existing knowledge on the influence of parents’ networks is confirmed and refined, as ANETTE FASANG explains. The networks’ effects are not exclusively positive, as [...] Watch video

As explained in this video it is commonly assumed that logically incoherent decision-making is irrational and costly in that it can lead e.g. to a decrease in happiness or health. An example for this would be a patient reacting differently if doctors speak of a 90% success rate of a surgery instead of a 10% failure rate for the same procedure. The purpose of the study presented here was to examine if there is proof in the [...] Watch video

The study presented in this video evaluates data from observational towers, satellite pictures and other published data to compare the impact of land-cover change and land management change on climate. The results show that land management change within the same vegetation (e.g., harvesting a formerly untouched forest) has effects on climate change that are similarly large as effects of land-cover change (e.g., changing [...] Watch video

There are more than 7,000 languages spoken worldwide. Many languages have evolved from a common ancestry line but we do not yet know where all the languages have come from and why there is such a great diversity. To find out how languages are related and form a family, linguists compare them by sifting through dictionaries, grammars or word lists. Recently, scholars have proposed automatic methods to compare languages [...] Watch video

The Arctic sea ice is the ice that is floating on the Arctic Ocean. In recent decades, this pack ice has been disappearing very rapidly. So the question arises when the Arctic sea ice will be completely gone. DIRK NOTZ has examined this using the Arctic summer sea ice in September as example. As he explains in this video, his research group combined satellite observations with model simulations and found a clear linear [...] Watch video

Risk perception is not only an individual but also a social phenomenon. The experiment presented in this video examines the development of perceived risk over the course of a communication chain: The first person got a balanced overview on a chemical and its risks then information was passed on from person to person. WOLFGANG GAISSMAIER elaborates how this set up led to an amplification of risk perception and the [...] Watch video

Modern humans colonized the whole planet and replaced all other hominids, such as Neanderthals. This evolvement raises interesting evolutionary questions concerning both species. The paleoanthropological research presented in this video looks at a moment in time when both co-existed. In order to find out about the differences between them, JEAN-JACQUES HUBLIN looks at both species’ use of technology, behavior, and [...] Watch video

Human development is determined by biology and culture. Biologically seen, the history of evolution has brought us certain cognitive biases, whereas our cultural legacy is built through interactions with other people. OLIVIER MORIN pursues research at the intersection of these two legacies and his particular area of interest is cultural transmission. As he explains in this video, one thing we inherit from evolutionary [...] Watch video
