Strawberry geranium (Saxifraga stolonifera) has been used in Japan as a herbal medicine to treat wounds and swelling, and continues to be an ingredient in food and cosmetics. Pharmacological studies have shown that extracts of strawberry geranium have antioxidant and antitumor activities. However, the anti-inflammatory effect of strawberry geranium on the skin had not been well characterized.
Multi-resistant pathogens are a serious and increasing problem in today's medicine. Where antibiotics are ineffective, these bacteria can cause life-threatening infections. Researchers at Empa and ETH Zurich are currently developing nanoparticles that can be used to detect and kill multi-resistant pathogens that hide inside our body cells. The team published the study in the current issue of the journal Nanoscale.
Excitation gratings created by interference of two light waves on a material allow investigating transport phenomena at a scale comparable to their wavelength. Going to the X-rays allows accessing these phenomena at the nanoscale.
An international team led by a Skoltech researcher has developed a method of fabrication for biodegradable polymer microcapsules, made more efficient by turning to an unusual source of inspiration - traditional Russian dumpling, or pelmeni, making.
Researchers at the Institute for Bioengineering of Catalonia (IBEC) led by Samuel Sanchez achieve a breakthrough in the field of biological robots by developing new biobots based on muscle cells that can swim at unprecedented velocities. These biobots also react to electrical stimuli and exert surprising forces thanks to their self-training with a 3D printed smart skeleton, opening the door to a new generation of stronger and faster biological robots based on muscle cells.
Nagoya University researchers and colleagues have uncovered a molecular pathway that enhances chemotherapy resistance in some pancreatic cancer patients. Targeting an RNA to interrupt its activity could improve patient response to therapy and increase their overall survival.
Researchers discovered that enriching cell-free vaccine extracts with cellular membranes increased the yields of protein-based vaccines by five-fold, significantly broadening access to potentially lifesaving medicines.
A new type of biopsy needle - which vibrates ultrasonically - greatly increases the amount of tissue obtained for pathologists to analyse. Currently, pathologists have to choose between a thick needle that provides a large sample, but causes pain, or a thin needle that is less painful, but gives lower quality samples. The ultrasonic needle solves this by providing large samples with thin needles, which could increase the effectiveness of medical procedures like cancer testing.
For more sustainability on a global level, EU legislation should be changed to allow the use of gene editing in organic farming. This is what an international research team involving the Universities of Bayreuth and Göttingen demands in a paper published in the journal "Trends in Plant Science".
Osaka University researchers produced a nickel phosphide nanoalloy catalyst (nano-Ni2P) on a hydrotalcite support for the hydrogenation of maltose to the in-demand sweetener maltitol. The catalyst is selective, highly active, air stable, effective under mild conditions and reusable. The hydrotalcite support and nano-Ni2P worked cooperatively, with the support increasing the turnover number by more than 300 times. The catalyst is expected to contribute to green and sustainable maltitol production.
