Physicists from Saarland University and the ESPCI in Paris have shown how liquids on solid surfaces can be made to slide over the surface a bit like a bobsleigh on ice. The key is to apply a coating at the boundary between the liquid and the surface that induces the liquid to slip. This results in an increase in the average flow velocity of the liquid and its throughput. This was demonstrated by studying the behaviour of droplets on surfaces with different coatings as they evolved into the equilibrium state. The results could prove useful in optimizing industrial processes, such as the extrusion of plastics.
The study has been published in the respected academic journal PNAS (Proceedings of the National Academy of Sciences of the United States of America).

Researchers study the link between malformations of the cerebral cortex and the occurrence of the neurological disease. Why does a structural irregularity in the temporal lobe make humans more susceptible to epileptic seizures? Experts have been searching for the answer to this question for a long time. A group of scientists at the Freiburg University Medical Center consisting of members of the University of Freiburg’s Cluster of Excellence Brain Links–Brain Tools has published a study involving a comparison of nearly 30,000 genes in the journal Cerebral Cortex. The team describes pathological processes in the brain tissue in developmental disorders of the cerebral cortex. The study is the largest of its kind to date. The authors of the study see the research as an excellent example of cooperation between fundamental researchers and clinicians.
Fuel cells generate electrical energy through a chemical reaction of hydrogen and oxygen. To obtain clean energy, the splitting of water into its components of hydrogen and oxygen is critical. Researchers at the University of Basel study how sunlight can be used for this purpose. The scientific journal Chemical Communications published their latest results.

Since January 1, 2016 Dr. Seraphine Wegner leads a new research group at the Max Planck Institute for Polymer Research. She will use light to control the organization of synthetic compartments and cells. Mainz. Wegner has been granted 1.4 million euros by the German Federal Ministry of Education and Research (BMBF) for her MaxSynBio Junior research group over the next five years. Her group, which is part of the MaxSynBio network, aims to control the organization of cells and cell-like compartments with light.
Unicellular microalgae smell dissolved minerals in the water as Chemists of the University Jena demonstrate in the current issue of “Nature Communications”
Diatoms are unicellular algae that are native in many waters. They are a major component of marine phytoplankton and the food base for a large variety of marine organisms. In addition, they produce about one fifth of the oxygen in the atmosphere and are therefore a key factor for our global climate.
By creating and using the first optical attosecond pulse, scientists from the Laboratory for Attosecond Physics measured the time it takes electrons inside atoms to respond to the electromagnetic forces of light.
We strive for better care for all patients through innovative tissue transplants This collaboration will strengthen not only Mecklenburg-Vorpommern as a recognised centre of tissue medicine. Our chief endeavours focus on improving care for patients of all age groups with innovative tissue transplants without long waiting-times. Founded last year in Rostock, the non-profit Mecklenburg-Vorpommern Tissue Bank (GBM-V gGmbH) is starting a collaboration with British medical company Tissue Regenix.

Advance in biomedical imaging: The University of Würzburg's Biocenter has enhanced fluorescence microscopy to label and visualise up to nine different cell structures simultaneously. Fluorescence microscopy allows researchers to visualise biomolecules in cells. They label the molecules using fluorescent probes, excite them with light and use the fluorescence thus triggered to get a microscopic image of the cell's structures.

How to make working with robots appealing for manufacturing employees, including those with severe disabilities. Robots are already becoming widely established in German factories. But how can companies be sure to split the work between people and robots such that human workers don’t lose out on the desirable tasks? An event marking the start of the AQUIAS project showcased approaches to guaranteeing quality of work for manufacturing employees, including those with severe disabilities.

Western doctors have long been sceptic of the usefulness of various methods of treatment used in traditional Chinese medicine. However, some forms of therapy from this ancient form of medicine, such as acupuncture, have now become established in western medicine. Researchers at Universitätsklinikum Erlangen at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have now examined a substance that is often used in traditional Chinese medicine – scorpion venom – and used it to treat particularly severe brain tumours, with surprising results.
How adaptive stimulation could make a significant difference for patients with neurological disorders such as Parkinson’s disease
Could potential side effects in the treatment of Parkinson’s disease with stimulation be avoided with a closed-loop approach, which constantly adapts to the symptoms? This is one of the key questions Dr. Ioannis Vlachos and his colleagues Taskin Deniz, Prof. Dr. Ad Aertsen, and Prof. Dr. Arvind Kumar address in a study that was now published in the journal “PLoS Computational Biology.”
With their chitinous shells, insects seem almost invulnerable – but like Achilles’ heel in Greek mythology, their impressive armor can still be attacked. Researchers at the universities of Bonn and Leipzig studied fruit flies (Drosophila) and discovered the molecular processes that are able to break through this protective casing. The enzyme chitinase 2 and growth factor idgf6 are especially important in correctly forming the insects’ shells. These findings are relevant for fighting parasites, and will be published in the professional journal “Scientific Reports.”
Michael R. Hamblin, Professor of the famous Harvard Medical School in Boston, says in a recent publication : “Infrared-A appears to be the solution, not the problem. It does more good than bad for the skin.” This is especially true when the skin is exposed to the appropriate irradiance and dose of infrared-A (near infrared NIR) similar to daily sun exposure received by people in real life. Specific protection against the Sun’s infrared-A is therefore unnecessary. As far as ultraviolet radiation is concerned, an adequate protection is still required.
