Scientists have developed a method to visualize and quantify alternative structures of RNA molecules. These alternative RNA ‘shapes’ can have important functional relevance in viruses and bacteria.

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.

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.
