Genetic insights shed light on how and where bacteria form brightly coloured colonies without pigments

Life Sciences - Jul 12
Life Sciences

Some bacteria form colonies that display striking, reflective colours. New genetic insights into the formation of such colours allowed an interdisciplinary, international team of researchers to identify the environments and bacterial groups in which these colours are found. Doing so, the team has made a start in understanding the function of these colours in bacteria. The findings, which are published today in the scientific journal Proceedings of the National Academy of Sciences (PNAS), might have implications for the development of new innovative materials that use bacteria to replace non-sustainable dyes.

Rising sea levels spell danger for shorebirds such as oystercatcher
Research by James Cook University in Australia involving Radboud scientists shows that rising sea levels will drastically reduce the number of shorebirds in Europe. The number of oystercatchers on three Waddeneilanden will decline an additional 56 to 79 percent over the next 100 years due to sea level rise.

Smarter incentives prevent grid congestion
Doctoral students Bart van der Holst and Gijs Verhoeven investigated financial measures for grid operators to make better use of the existing grid capacity. Our electricity grid cannot keep up with the energy transition. New schools, businesses and neighborhoods have to wait for a connection and solar panels are already switched off at peak times.

’Open-washing’ generative AI: how Meta, Google and others feign openness
The past year has seen a steep rise in generative AI systems that claim to be open. But how open are they really? New research shows there's widespread practice of 'open-washing' by companies like Meta and Google: claiming brownie points for openness while evading actual scrutiny. The question of what counts as open source in generative AI takes on particular importance in light of the EU AI Act that regulates "open source" models differently, creating an urgent need for practical openness assessment.

Midnight sun on Svalbard: expedition to phytoplankton
On July 5, 2024, five researchers from Radboud University will travel to the far north to research climate change on Svalbard. For a week, the scientists, led by earth scientist Wytze Lenstra, will take samples of the sea floor and water column in one of the fjords. The archipelago is seen as a "natural laboratory" for studying the impact of climate change in the future: these Arctic regions are warming up to about four times faster than the global average.

Can a computer chip have zero energy loss in 1.58 dimensions?
Can a computer chip have zero energy loss in 1.58 dimensions?
What if we could find a way to make electric currents flow, without energy loss? A promising approach for this involves using materials known as topological insulators. They are known to exist in one (wire), two (sheet) and three (cube) dimensions; all with different possible applications in electronic devices.

TU Delft launches future proof research reactor with cold neutron source
More advanced and faster research is possible with the commissioning of the cold neutron source and the improved instruments of TU Delft Reactor Institute (RID) as of 27 June 2024. The first results of research are expected in October 2024, around the official reopening of the reactor. In recent years, the TU Delft team together with more than 10 national and international partners and suppliers have realised a technical masterpiece.

Fewer measurements required to determine level of pharmaceutical residues in wastewater due to new model
It is becoming increasingly obvious that pharmaceutical residues in wastewater are damaging to the environment, making it imperative that wastewater is tested for such residues. However, wastewater measurements are expensive and time-consuming. A new model developed by Radboud University-affiliated environmental scientist Caterina Zillien can be used to determine the amount of pharmaceutical residues in wastewater - and their exact origin - every bit as precisely as actual measurements.

Innovative thermostat increases your comfort in heat and cold
Innovative thermostat increases your comfort in heat and cold
The innovative thermostat BRYS, developed by industrial designer Lenneke Kuijer with her Veni grant, is designed to help residents keep their homes up to nine degrees cooler in the summer heat. BRYS also helps train our bodies to stay comfortable at temperatures between 17 and 28 degrees Celsius. Summers are getting longer and hotter, even in the Netherlands.

Informal care is difficult to combine with work
Informal care has a huge impact on your working life. Informal carers earn less per hour and are less satisfied with their job. This is the conclusion reached by sociologist Klara Raiber, who will defend her PhD dissertation at Radboud University on 2 July. With more people becoming informal carers, the researcher says it is high time for structural support to be provided.

’Even negative research findings deserve to be published - others can learn from them’
Postdoctoral researcher Florencia Abinzano was nominated for the Trial and Error award, established to create more awareness for open science: the open sharing of all research results, positive and negative, in science. Scientific research does not always go as it was conceived or hoped for. Sometimes, your hypothesis doesn't work out, mistakes may be made.

Consider embedding platform work in the job market
Platform work, such as driving for Uber or freelancing through Upwork, is booming, but it also raises questions about employment rights. A new EU directive should soon make it easier for platform workers to prove that they are not self-employed but employees. But what then? According to labour law researcher Jorn Kloostra, not enough attention has been paid to how platform work should be given a sustainable place in the Dutch job market.

Age of organic carbon important factor in ocean carbon storage
Age of organic carbon important factor in ocean carbon storage
The ocean can store carbon and act as a carbon sink, and it can be a carbon source. The difference in 'age' of the organic carbon already present in the ocean and the carbon that is supplied determines whether the ocean acts as a carbon sink or source. Researchers from Nanjing universities and Utrecht University created the first sink or source world map that can be used when deciding where to invest in organic carbon storage in the ocean.

Excessive social media use during pregnancy linked to depression
Intensive and problematic social media use during pregnancy can lead to depressive symptoms. This is evident from new doctoral research by Tilburg University. "More attention needs to be paid to these risk factors for mental health problems, which can have unfavorable outcomes for both mother and child." For the past 30 years, Tilburg University has conducted extensive research into the general well-being of women during pregnancy.

Model explains spontaneous explosions of delays in supply chains
A group of scientists has developed a model that explains how schedule-based systems, such as supply chains and railways, can be prone to spontaneous explosions of large-scale delays. The researchers recommend system operators to prioritize resilience, alongside efficiency, for better long-term outcomes.
