In Huntington’s disease, a faulty protein aggregates in brain cells and eventually kills them. Such protein aggregates could, in principle, be prevented with a heat shock protein. However, it is not well known how these proteins interact with the Huntington’s disease protein. New research by Patrick van der Wel (University of Groningen, the Netherlands) and colleagues at the University of Texas explains how they work.

Plastics are among the most successful materials of modern times. However, they also create a huge waste problem. Scientists from the University of Groningen (The Netherlands) and the East China University of Science and Technology (ECUST) in Shanghai produced different polymers from lipoic acid, a natural molecule. These polymers are easily depolymerized under mild conditions. Some 87 percent of the monomers can be recovered in their pure form and re-used to make new polymers of virgin quality. The process is described in an article that was published in the journal Matter on 4 February.

One of the properties that make a planet suitable for life is the presence of a weather system. Exoplanets are too far away to directly observe this, but astronomers can search for substances in the atmosphere that make a weather system possible. Researchers from SRON Netherlands Institute for Space Research and the University of Groningen have now found evidence on exoplanet WASP-31b for chromium hydride, which at the corresponding temperature and pressure is on the boundary between liquid and gas.

The evolutionary interaction between insects and plants has created complex dependencies that can have surprising outcomes. Casper van der Kooi, a biologist at the University of Groningen, uses an interdisciplinary approach to analyse the interaction between pollinators and flowers. In January, he was first author of two review articles on this topic.

The Seychelles warbler is a cooperatively breeding bird species, meaning that parents often receive help from other birds when raising their offspring. A study led by biologists from the University of Groningen shows that the offspring of older females have better prospects when they are surrounded by helpers.

New physics-based technologies allow scientists to study the dynamics of viruses and may eventually lead to new treatments. In his role as physical virologist, Wouter Roos, a physicist at the University of Groningen, together with two longtime colleagues, has written a review article on these new technologies, which was published in Nature Reviews Physics on 12 January.

The lockdowns that resulted from the COVID-19 pandemic have reduced greenhouse gas emissions. However, in the recovery phase, emissions could rise to levels above those projected before the pandemic. It all depends on how the stimulus money that governments inject into their economies is spent.

The observation of nonlinearity in electron spin-related processes in graphene makes it easier to transport, manipulate and detect spins, as well as spin-to-charge conversion.This brings spintronics to the point where regular electronics was after the introduction of the first transistors.

Organic chemists from the University of Groningen and the Dutch multinational company AkzoNobel, a major global producer of paints and coatings, developed a process that allows them to turn biomass into a high-quality coating using light, oxygen and UV light.

Is gravity a quantum phenomenon? Together with colleagues from the UK, Anupam Mazumdar, a physicist from the University of Groningen, proposed an experiment that could settle the issue. In a new paper, which has a third-year Bachelor’s student as the first author, Mazumdar presents a way to reduce background noise to make this experiment more manageable.

Theoretical studies of the dynamics of photoinduced processes require numerous electronic structure calculations, which are computationally expensive. Scientists from the University of Groningen developed machine learning-based algorithms, which reduce these computations significantly.

Adrenal tumours are present in around five percent of the population and are often found incidentally when an abdominal scan is made for an unrelated reason. It is difficult to determine from the scan whether such a tumour is benign or malignant. A new method uses an algorithm that differentiates between the two tumour types based on the pattern of steroid metabolites in the patient’s urine. The method, which was published this summer, is just one of the many uses for the algorithm, says Michael Biehl, Professor of Computer Science at the University of Groningen.

Scientists are working on new materials to create neuromorphic computers, with a design based on the human brain. Materials scientists from the University of Groningen analysed the behaviour of strontium titanium oxide, a platform material for this type of application, and used the 2D material graphene to probe it

A high concentration of salt or sugar in the environment will dehydrate microorganisms and stop them from growing. Scientists from the University of Groningen elucidated the structure of a transport protein OpuA, that imports glycine betaine to counter this.

Thermoelectric materials can turn a temperature difference into electricity. Organic thermoelectric materials could be used to power wearable electronics or sensors; however, the power output is still very low. An international team led by Jan Anton Koster, Professor of Semiconductor Physics at the University of Groningen, has now produced an n-type organic semiconductor with superior properties that brings these applications a big step closer.

The SARS-CoV-2 coronavirus RNA genome structure was studied in detail by researchers from the University of Groningen, the International Institute of Molecular and Cell Biology in Warsaw, and Leiden University. The RNA structures are potential targets for the development of drugs against the virus.
