A fake Christmas tree may be more popular, but here’s a new reason to appreciate the real thing: Researchers have identified a group of anti-inflammatory compounds in the bark of the Scotch pine — widely used for Christmas trees — that they say could be developed into food supplements or drugs for treating arthritis and pain. The compounds, which show promise in preliminary cell studies, are likely to be found in other pine species as well, the scientists say.
Anti-inflammatory compounds have been found in a wide variety of plant species, but this is believed to be the first time that they’ve been identified in a species that is used commonly for Christmas trees, the researchers say. The compounds identified were phenolics, a class of highly-active plant chemicals that have been increasingly tied to beneficial health effects. The study is scheduled to appear in the Dec. 29 print issue of the Journal of Agricultural and Food Chemistry, a peer-reviewed publication of the American Chemical Society, the world’s largest scientific society.
“The preliminary study showed that highly purified preparations of pine bark extract have potent anti-inflammatory effects. In the future, this may mean that people with arthritis may ease their pain by eating food supplements made from Christmas trees,” says study leader Kalevi Pihlaja, Ph.D., a chemistry professor at the University of Turku in Finland. He cautions that the extract used in this study has not yet been tested in animals or humans. Until those studies are done, he adds, no one knows how much might be needed to obtain health benefits or whether there are any side-effects.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
