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.
In the current issue of Nature Communications, Researchers from Goethe University report on a process that uses pressure to deliver chemical probes in a fine-tuned manner into living cells. Tracing distinct proteins in cells is like looking for a needle in a haystack. In order to localize proteins and decipher their function in living cells, researchers label them with fluorescent molecules. However, the delivery of protein markers is often insufficient. A group of researchers from the Goethe University, working in close collaboration with US colleagues, has now found a solution for this problem. In the current issue of Nature Communications, they report on a process that uses pressure to deliver chemical probes in a fine-tuned manner into living cells.
