Great tits detox at the expense of a lower life expectancy

Some males of great tits that faced higher energetic costs during their reproductive phase upregulated the concentration of an enzyme important for detoxifying free radicals. Together with other physiological reactions like the loss of weight and a higher level of stress hormones, harder-working birds compensated higher energetic demands in a way that had no direct consequences for their offspring or their own survival. This is what researchers of the Max Planck Institute for Ornithology have found. However, birds with a higher concentration of the enzyme had a lower overwinter survival. This seems to be the physiological key mediating the trade-off between reproduction and survival. (Mehr in: Pressemitteilungen – idw – Informationsdienst Wissenschaft)

How hantaviruses infect lung cells

Hantaviruses cause severe and sometimes fatal respiratory infections, but how they infect lung cells has been a mystery. Researchers report that hantaviruses gain entry to lung cells by ‚unlocking‘ a cell-surface receptor called protocadherin-1 (PCDH1). Deleting this receptor made lab animals highly resistant to infection. The findings show that targeting PCDH1 could be a useful strategy against deadly hantavirus pulmonary syndrome.

Jacobs University researchers discover how immune proteins group together

The surface of our body cells is covered in proteins that have many tasks. Some of these proteins, the so-called MHC proteins, help the immune system to recognize whether the cell that carries them has become infected by a virus or a bacterium, or whether it has even become part of a tumor. So, the MHC proteins are crucially important to keep us healthy. Researchers at Jacobs University Bremen have now developed a versatile method that can help to understand the interaction of these proteins.

Like the earthworm: new breathing material lubricates itself when needed

Earthworms are always clean, even if they come from moist, sticky soil. They owe this to a dirt-repellent, lubricating layer, which forms itself again and again on its skin. Researchers at INM have now artificially recreated this system of nature: They developed a material with a surface structure that provides itself with lubricant whenever pressure is applied. Because the lubricated material reduces friction and prevents the growth of microbes, scientists can envision numerous applications in industry and biomedicine.

Enabling a plastic-free microplastic hunt: "Rocket" improves detection of very small particles

Environmental researchers at the Leibniz Institute for Baltic Sea Research Warnemünde (IOW) have developed a novel mobile device for recording microplastics in surface waters. They call it the “Rocket”, a design with which depending on the amount of suspended matter in the water up to 60 litres per minute can be sucked through four cartridge filters, and which is particularly advantageous for sampling the fine fraction of the microplastic in the range down to 10 µm. The scientists were specially challenged by the fact that plastic had to be avoided as far as possible. The successful results of the test phase have now been published by them in the international scientific journal “Water”. (Mehr in: Pressemitteilungen – idw – Informationsdienst Wissenschaft)

New cell movement process key to understanding and repairing facial malformations

There’s a better way to decipher DNA’s epigenetic code to identify disease

A new method for sequencing the chemical groups attached to the surface of DNA is paving the way for better detection of cancer and other diseases in the blood. These chemical groups mark one of the four DNA ‚letters‘ in the genome, and it is differences in these marks along DNA that control which genes are expressed or silenced.

„Science“-Study: Proteins surf to mitochondria – Novel transport pathway discovered

Proteins are essential constituents of cells and their compartments. Prof. Johannes Herrmann, a researcher at the Technische Universität Kaiserslautern, and his team discovered a novel mechanism by which newly synthesized proteins reach their respective target compartment in the cell. Proteins destined to mitochondria, the cell’s powerhouse, are not directly transported to mitochondria but are directed to the surface of the endoplasmic reticulum, where they “surf” along its surface. As shown in the renowned journal “Science”, this so far unknown mechanism keeps newly synthesized protein transport-competent and might prevent their aggregation.

Canine melanoma study identifies genetic basis of disease; potential drug targets

Medical researchers have used multiple genomic analysis techniques to identify several gene mutations that could be the keys to what drives melanoma in dogs. Following the path from human melanoma, the findings of recurring molecular changes in canine melanoma can help veterinary physicians pinpoint potential new treatments for dogs. Likewise, human physicians will view these changes in light of the type of melanoma that occurs in non-sun exposed areas in the mouth, or other mucosal surfaces.

Inspiring students to love science

Of course, he was surprised. After all, no former student had ever donated 50,000 euros to his or her professor at Jacobs University Bremen. “This was an unbelievably momentous occasion for me,” says Sebastian Springer. A few years ago, the biochemist had seen potential in an applicant from far-away Yemen that no-one else saw. Other universities and colleges had rejected Hashem Al-Ghaili’s application. But not Springer, who awarded him a place to study at Jacobs University. Al-Ghaili, who was to later become a science communicator with 27 million Facebook followers, expressed his gratefulness in the form of a donation. Springer has invested the funds in cancer research equipment. (Mehr in: Pressemitteilungen – idw – Informationsdienst Wissenschaft)

Pigs form a visual concept of human faces

Contrary to previous studies, pigs appear to have better visual discrimination abilities than had previously been assumed. Cognition researchers from the Messerli Research Institute showed in a new study that pigs not only discriminate between front and back views of human heads but also that the animals apparently use certain facial features such as our eyes or mouth as cues. The results shed a new, more positive light on the previously rather pessimistic opinion of the visuo-cognitive abilities of these clever animals.
