Can a Single Model Explain Different Functions of the Human Brain?

The human brain has many functions; for instance, it allows people to focus on particular objects and ignore others, or to remember events in the past. TATJANA TCHUMATCHENKO uses mathematical equations in order to understand how our brain achieves this. Previous research in this area has developed models that explain single questions, such as ‘How does memory work?’. However, as she describes in this video, the brain has a set of hardware parameters that can be used to synthesize many different functions. Tchumatchenko’s research group has therefore focused on three of these: attention, memory, and contrast invariance. Their aim was to answer whether all three have the same underlying basic principles and can be explained by a single model. Their experimental results confirm this hypothesis and they found that the way to control the three functions is to control the neurons. These findings have implications for pharmaceutical research on drugs that act on the neuronal channel.

Gravity is the decisive force driving the formation and evolution of cosmic structures. BJÖRN MALTE SCHÄFER is interested in the properties of gravity on very large scales as well as in very specific questions concerning structure formation, such as how galaxies acquire their angular momentum, how they start rotating, and how galaxies interact with surrounding structures. Currently, the understanding of gravity is based on general relativity. As is explained in this video, the research group tried to investigate the properties of gravity by making observations on very large scales, i.e. they look at the formation and evolution of structures in the universe, namely galaxies. Applying this method, they have found good evidence to further support the idea of general relativity as the theory of gravity on large scales. This allows to make specific predictions for future surveys and future experiments.

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 material also poses problems, however, as it is sensitive to humidity, heat, and light. His research team has found a way to tackle these challenges by creating a new composition that proves more stable and by adding a polymeric protective layer.

Recent research has shown that solid materials can be classified based on their electronic band structure using the abstract mathematical concept of topology. In this video MARKUS MORGENSTERN explains how interdisciplinary research found the first material of a topological type called “weak topological insulators” and how this might solve problems in the field of quantum computation.

Media Control means uses of media in terms of political power, e.g., censorship. By the means of discourse analysis, the research presented in this video investigates the communication of authorities and asks how they communicate about media they want to censor. As STEPHAN PACKARD explains, his analysis reveals two competing questions in those discourses. One is where and with what legitimacy a line is drawn between controlled communication and controlling agency; the other is which rules are generally governing the, possibly censored, communication in question.

Galaxies are filled with particles traveling very close to the speed of light; these are so-called ultra-relativistic particles. Until recently, it was very difficult to investigate these particles because of a lack of good observational data and they have been rather neglected in the study of astrophysics. As JIM HINTON explains in this video, his research group is interested in understanding how these particles influence astrophysical processes. For this, they need to find out how and where these particles are accelerated and what their impact is. Focusing on high-energy gamma rays and exploring the morphology and spectrum of the gamma ray emission from their sources, they found – in contrast to what was previously assumed – that the acceleration of particles to such high energies is rather common in nature. The impact of these non-thermal relativistic particles on astrophysical processes cannot be ignored anymore. Thus, the Cherenkov Telescope Array (https://www.cta-observatory.org/) has been initiated; this multinational project will be the world's largest and most sensitive high-energy gamma ray observatory.

The compromise effect can be observed in the consumer’s tendency to avoid extreme ends of the available range when making purchasing decisions. In this video, MARKO SARSTEDT investigates the origins of the compromise effect. Describing an experiment that interrogates the effects of a lowering of cognitive capability on purchasing decisions, Sarstedt argues that rather than involving fast or intuitive decision making, the compromise effect is grounded in deliberate and demanding thought processes. The research provides a platform for further work examining the links between other effects (e.g., the attraction effect and the phantom decoy effect) and cognitive depletion.

How Can a 3D-Map of Dust Help Measure Distances in our Milky Way?

The dust in our Milky Way is the constituent of the cosmic life cycle. It is the substance from which new stars are generated and it is what stars become once they die. Unfortunately, as HANS-WALTER RIX explains in this video, the dust turns distance measurements of stars in the Milky Way into a difficult endeavor, because it dims objects and blocks light from the material behind it. In his project two common methods of distance measurement are therefore used in combination to sketch a 3D map of Milky Way dust: first the parallax, which uses the orbit character of the earth in order to check on the stars’ respective positions, and second, the calculated brightness of stars which allows for an estimate concerning the amount of dust in front of each star. The so created 3D map helps to limit errors in distance calculations due to a feasible dust exclusion, made possible by the localization of dust. The conversion of observed quantities into physical quantities thus becomes possible.
