North Atlantic Current may cease temporarily in the next century
Posted on:30 December 2019

Simulations by scientists from the University of Groningen and Utrecht University showed that it is unlikely that the North Atlantic Current , which is responsible for the mild climate in northwestern Europe, will come to a complete stop. However, there is a 15 percent likelihood that there will be a temporary change in the current in the next 100 years.

Hot electrons harvested without tricks
Posted on:15 November 2019

Some photons carry too much energy for the material of solar panels to absorb. These photons produce ‘hot electrons’, and the excess energy of these electrons is converted into heat. Scientists from the University of Groningen have now shown that it may be easier than expected to harvest this excess energy.

Antacid helps tuberculosis bacteria to survive
Posted on:19 August 2019

University of Groningen scientists, with an international team of colleagues, have now discovered a key mechanism in the tuberculosis bacteria which prevents the immune cells from killing them: the bacteria produce a unique type of antacid which gives the immune cells indigestion.

New Zealand’s biodiversity will take millions of years to recover
Posted on:05 August 2019

The arrival of humans in New Zealand, some 700 years ago, triggered a wave of extinction among native bird species. Calculations by scientists from the University of Groningen in the Netherlands and Massey University in New Zealand show that it would take at least 50 million years of evolution to restore the biodiversity that has been lost.

Small-volume, high-throughput organic synthesis
Posted on:09 July 2019

University of Groningen Professor of Drug Design, Alexander Dömling, has devised a method to rapidly synthesize thousands of new molecules and evaluate their properties as potential drugs. In a paper published by Science Advances on 5 July, he shows that this method works well when applied to boronic acid chemistry, an important technique in synthetic organic chemistry.
