The integrated circuitry of microchips is getting ever smaller. New technologies even promise molecular circuits. But at this length-scale, the normal laws governing conductance have to make way for quantum laws. Ryan Chiechi and co-workers explored some of these quantum effects in molecular circuits in a paper published on 20 December in Nature Communications.

University of Groningen / Science LinX present five images for Nobel-winning motors by Ben Feringa

University of Groningen professor Marco Fraaije is looking to improve enzymes to make them suitable for use in industry. He has already improved a number of such enzymes in his work on the European research project ROBOX. A new film explains the project.

All textbooks describe the cyclin-dependent kinase complex as the one and only/exclusive regulator of the eukaryotic cell cycle. But now University of Groningen scientists have found evidence that a metabolic oscillator acts as the 'conductor' of cell division. Their results were published online in the journal Molecular Cell on December 15.

Peter van Abswoude spent over four years working with electron beams. He now teaches at a school. His ambition is to inspire pupils and spark enthusiasm for his subject of physics.

As the number of seats in Stockholm is limited to say the least, the University of Groningen organized its own Nobel lecture in the Martinikerk on 30 November. For Ben Feringa, the official academic ceremony with professors in gowns was the ideal dress rehearsal for the award ceremony on 10 December. The mood was relaxed, and the audience hung on Feringa’s every word.

The University of Groningen is looking for an artist in residence for a project that it is working on with two Max Planck institutes. The artist will develop an art project on synthetic biology (a field of biology on the interface between molecular biology, cell biology and engineering) that will foster dialogue about this field.

The visible matter in the universe is arranged in a pattern: galaxies and gas clouds form a kind of foam in which filaments of matter surround voids. But alongside this visible matter are vast quantities of ‘dark matter’ and ‘dark energy’, both of which are invisible. University of Groningen PhD student Patrick Bos has demonstrated that it is possible to study the structure and nature of these invisible building blocks.

Birds facing many predators at their nests have longer incubation spells than birds that do not have this problem. The latter can more easily change shifts without risking foxes or crows discovering their nests. This is what Czech and Belgian biologists Bulla and Kempenaers and researchers from Groningen have discovered. The findings were published in the journal Nature on 24 November.

The cichlids of Lake Victoria are a textbook example of rapid evolution. Biologists suspect that the visual environment underwater (light and turbidity) is an important driver in the formation of new species, but direct evidence has been hard to come by. Now supporting evidence has emerged from the University of Groningen aquariums. The results were published in The American Naturalist.

Our cells use all kinds of proteins to import useful substances from their environment. These protein pumps are powered by a stream of particles, often sodium ions, that work a bit like water turning a water wheel. How this really works was shrouded in mystery, but University of Groningen biologists have now solved the puzzle.

Surprisingly practical inventions often issue from the University of Groningen’s labs. Not only the scene of fundamental research, the labs are also favoured by engineers who use the latest technology to develop practical applications for their findings. The new Groningen Engineering Center (GEC) should give new impetus to engineering research and teaching at the University.

The university of Groningen will host FameLab, the international science communication competition for young scientists.

Universiteiten, hogescholen en het voortgezet onderwijs werken al geruime tijd samen in regionale netwerken. Ook Science LinX is onderdeel van zo'n netwerk in Noord Nederland. Maar nu dreigt de overheid de financiering stop te zetten. De samenwerkende netwerken doen daarom de onderstaande oproep aan het ministerie van OCW om toch geld te reserveren voor deze netwerken.

Different types of evidence often pass the review during a court case. But how do judges balance ‘hard’ data, for example the chances that the DNA trace comes from the suspect, against witness statements? Mathematician Charlotte Vlek has developed a solution, but not one that can be used in every case.

At the end of September, 42 teachers, 54 school pupils and 45 members of university and science centre staff from 10 European countries met in Kiel, Germany for the final conference of the European IRRESISTIBLE project.

The first data from the Gaia satellite was published on Wednesday. Astronomers from the University of Groningen's Kapteyn Astronomical Institute couldn't wait to get their teeth into it.

We’re used to computer chips increasing in speed and capacity. This is achieved by making transistors smaller, so that more fit on the computer processor. However, miniaturization is nearing its limit. One solution may be transistors that operate on electron spin rather than a charge. Sander Kamerbeek defended his PhD thesis on this topic on 9 September.

As islands grow in the Wadden Sea, the new land hosts a succession of plant species. Biologists are familiar with this phenomenon. What they didn’t know was which bacteria live in the bare sands and ever-richer soils during this natural ecological succession. Francisco Dini-Andreote has now filled this gap in our knowledge.

It is going to be like Harrod's Christmas sale. Astronomersare about to embark on a mad trolley dash through the galaxy. It’s not t-shirts or the latest gadgets that they’re after, but the brightness and position of a billion stars, as recorded by the Gaia satellite. The data will be made publicly available on Wednesday 14 September.

The work of University of Groningen PhD student Vahideh Faghihi will make the calibration of thermometers even more accurate. No big deal for the average user, but important to climate scientists.

Albert Einstein spent the last twenty years of his career trying to unify physics in one theory, without success. The most nagging aspect was his failure to describe gravity in terms of quantum mechanics. Physicists around the world are still working on the problem and believe they will find the answer by studying the early Universe. The cosmological models developed by University of Groningen PhD student Marco Scalisi promise significant progress.

University of Groningen chemist Ryan Chiechi has produced a device that can be switched by light from low to high conductance at the speed of picoseconds.
