Biomass is an interesting source of carbon-based molecules. It is also underused because some 25 percent of all plant biomass is in the form of lignin, a biopolymer that, so far, can only be used as a solid fuel. A team of scientists, including ‘enzyme engineer’ Marco Fraaije from the University of Groningen, has now developed an enzyme that can put a lignin monomer to use in chemical synthesis.

When you make conducting wires thinner, their electrical resistance goes up. This is Ohm’s law, and it is generally right. An important exception is at very low temperatures, where the mobility of electrons increases when wires become so thin that they are effectively two-dimensional. Now, University of Groningen physicists, together with colleagues at Brest University have observed that something similar happens with the conductivity of magnons, spin waves that travel through magnetic insulators, much like a Mexican wave through a stadium.

Thirty-eight Chinese cities have reduced their emissions of planet-warming carbon dioxide (CO2) despite growing economies and populations for at least five years. A further 21 cities have cut CO2 emissions as their economies or populations have ‘declined’ over the same period - defined as passively emission declined cities. This is revealed by new research from the Universities of Birmingham (UK), Groningen (Netherlands), and Tsinghua University (China).

Wheat is a key source of nutrition for people across the globe. Rising temperatures may affect wheat harvests: the yield is likely to increase at high latitudes and decrease in low latitudes, meaning that prices for the grain are likely to change unevenly and increase in much of the Global South, enhancing existing inequalities. To assess the consequences, an international team which includes University of Groningen professor of Climate and Environmental Change Richard Bintanja has developed a new climate-wheat-economic ensemble modeling approach.

Cells with a nucleus contain compartments with the machinery to carry out specific tasks. Although bacterial cells have no such compartments, evidence suggests that even these cells are not homogeneous. Biochemists from the University of Groningen have now mapped diffusion rates inside a bacterial cell, which identified distinct regions.

Deep evolution casts a longer shadow than previously thought, scientists report in a new paper published the week of Aug. 1 in the Proceedings of the National Academy of Sciences. Smithsonian scientists and colleagues, including University of Groningen emeritus professor Jeanine Olsen, looked at eelgrass communities—the foundation of many coastal marine food webs along the north Atlantic and Pacific coasts—and discovered their ancient genetic history can play a stronger role than the present-day environment in determining their size, structure and who lives in them.

Mathematics and music are to some extent related. So, when Aditya Ganesh, amateur musician and Master’s student of Computing Science at the University of Groningen, sat in a lecture on complex behaviour created by a simple formula, he saw the potential for a new music piece. It took him six months to convert a logistic map into a nearly eight minutes’ long composition called ‘Feigenbaum’s Orbit’.

The intermittent supply of green electricity requires large-scale storage to keep our power grids stable. Since normal batteries do not scale very well, the idea of using flow batteries, which store electricity in a fluid is attractive. Scientists at the University of Groningen, the Netherlands, have designed a flow battery electrolyte that is cheaper and is based on an organic compound, rather than a metal.

If the UN Sustainable Development Goal to lift over one billion people out of poverty were to be reached in 2030, the impact on global carbon emissions would be minimal. That sounds good; however, the main reason for this is the huge inequality in the carbon footprint of rich and poor nations. This conclusion was drawn by scientists from the Energy and Sustainability Research Institute of the University of Groningen (the Netherlands), together with colleagues from China and the US.
