Scientists solve century-old chemistry riddle
When two solutions of oppositely charged polymers (polyelectrolytes) are mixed, phase separation occurs leading to the formation of a polymer-rich phase and a supernatant phase. The precise distribution of all components, that is polyelectrolytes and counterions, had not yet been determined. Researchers at the University of Twente can now measure quantitatively exactly where these components are distributed using Nuclear Magnetic Resonance (NMR) spectroscopy.

The role of brain connections in insomnia explained
The role of brain connections in insomnia explained
Insomnia is a common problem that also increases the risk of depression. Unfortunately, we do not yet sufficiently understand the underlying neurobiological mechanisms. Research by neuroscientist Tom Bresser shows that the white matter in the brain, which connects different brain areas, differs in people with insomnia compared to people without sleep problems.

A route to scalable Majorana qubits
A route to scalable Majorana qubits
Researchers at QuTech have found a way to make Majorana particles in a two-dimensional plane. This was achieved by creating devices that exploit the combined material properties of superconductors and semiconductors. The inherent flexibility of this new 2D platform should allow one to perform experiments with Majoranas that were previously inaccessible.

Papiamentu should be a structural part of reading instruction on ABC islands
On the islands of Aruba, Bonaire and Curaçao, children until recently only learned to read in a language foreign to them: Dutch. It was not until 2001 that their native language, Papiamentu, was also introduced as a language of instruction in primary schools. Sociologist and educational expert Melissa van der Elst-Koeiman studied the bilingual reading development of children in the senior years of primary school on the islands.

Inclusive integration policy can reduce perception of diversity as a threat
Increasing ethnic and racial diversity in Western societies often accompanies feelings of threat among the ethnic majorities of a country. New research from Tilburg University shows that an inclusive integration policy can reduce the perception of diversity as a threat. The research suggests that policies that give immigrants more equal rights are particularly effective in promoting social cohesion and reducing tensions in Western societies.

How long will the African population continue to grow?
According to the United Nations (UN) population projections, the population of Africa will continue to grow strongly in the course of this century, while on other continents population growth will decline in the near future. New research by Jeroen Smits from Radboud University and Lamar Crombach from ETH Zurich suggests that population growth in Africa might slow down faster than predicted by these projections.

Sustainable plastics are not a solution, researchers warn
With hundreds of millions of tonnes of plastic produced and used on a yearly basis, it's no surprise that people are looking for alternatives. Yet so-called 'sustainable plastics' are not a silver bullet, warn researchers Sara Gonella and Vincent de Gooyert from Radboud University. When looking at the full impact of these plastics, they are often not nearly as sustainable as they pretend to be, they argue.

Freeze response in dangerous situations is actually very useful
When people face an acute threat, they tend to react in one of three ways: fight, flight or freeze. A doctoral research project conducted at Radboud University by Felix Klaassen and defended on the 5th of June shows that the freeze response can be really helpful in dealing with a situation in a well-considered way.

Thawing permafrost: not a ticking time bomb, but cause for urgent concern
Thawing permafrost: not a ticking time bomb, but cause for urgent concern
The thaw of permafrost is not a global climate 'tipping point'. That is the conclusion of an international group of scientists, including earth scientist Moritz Langer. Rather, permafrost soils are thawing along with global warming. "There is no safe margin within which the Earth can warm up, as a tipping point suggests." Permafrost soils store large amounts of organic carbon in the form of dead plant material.

More wolves does not necessarily equal fewer foxes or badgers
The assumption that the numbers of smaller predators will decline when large predator populations rise, is not necessarily valid. For mammals in Europe, this relationship appears to exist only in specific cases. Utrecht biologists Thomas van Schaik, Marijke van Kuijk , and Liesbeth Sterck conclude this based on a literature review they conducted, which was recently published in the scientific journal Mammal Review.

30 million euros for research into climate change feedbacks
30 million euros for research into climate change feedbacks
Climate change can accelerate due to feedback mechanisms: complex phenomena caused by climate change that in turn can further drive climate change. An example is the extra CO2 emissions from thawing permafrost. Research into the influence of feedback mechanisms in the long term has been ongoing, and modern climate change research is obviously happening as well, but the connection between the two has so far been underemphasized.
