At the invitation of the U.S. Department of Energy's Office of Basic Energy Sciences, 17 top experts in nitrogen research gathered to discuss nitrogen activation chemistry and the field's future. Their conclusions form a review article in the journal 'Science.'
In an interdisciplinary collaboration, researchers at the University of Münster have developed a method of visualizing an important component of the cell membrane in living cells. Therefore, they synthesized a family of new substances. The study has been published in Cell Chemical Biology.
Researchers at the Ruhr-Universität Bochum have discovered why bioelectrodes containing the photosynthesis protein complex photosystem I are not stable in the long term. Such electrodes could be useful for converting light energy into chemical energy in an environmentally friendly way. However, the proteins, which are stable in nature, are not functional in semi-artificial systems in the long term because reactive molecules are formed that damage the photosystem I.
Certain types of bacteria and viruses are readily ejected into the atmosphere when waves break; others less so, researchers reported May 22. A team of chemists, oceanographers, microbiologists, geneticists, and pediatric medicine specialists are attempting to understand how far potentially infectious bacteria and viruses can travel and if those that pose the greatest risks to public health are among those most likely to escape the ocean.
A team of researchers in Japan developed a synthetic molecular code to script gene activation. The process, described in the Journal of the American Chemical Society, could help lead to future gene-based therapies for a wide array of diseases.
A study published by Brazilian researchers describes one of Xanthomonas citri's secretion systems and a signaling pathway that enhances its resistance against amoebae. Investigations might contribute for future forms of intervening and putting a stop on the development of X. citri, known for its persistency.
Chemist Vincent Rotello at UMass Amherst, with others at University College London, have developed a 'quick and robust' blood test that can detect liver damage before symptoms appear, offering what they hope is a significant advance in early detection of liver disease. Details appear in Advanced Materials. Their new method can detect liver fibrosis, the first stage of liver scarring that can lead to fatal disease if left unchecked, from a blood sample in 30-45 minutes.
When cells become stressed, they activate specific response patterns. Würzburg researchers have identified new details of these responses, which can help to get a better understanding of neurodegenerative diseases.
Hematopoietic Stem Cells (HSCs) give rise to blood and immune cells of the body, and are therefore essential for our survival. The group of Manuela Baccarini at the Max F. Perutz Laboratories, a joint venture of the University of Vienna and the Medical University of Vienna, has now shown how intracellular signalling can safeguard this delicate balance between activation and dormancy. Their results are published in the prominent journal Cell Stem Cell.
University of Illinois engineers built a 3D printer that offers a sweet solution to making detailed structures that commercial 3D printers can't: Rather than a layer-upon-layer solid shell, it produces a delicate network of thin ribbons of hardened isomalt, the type of sugar alcohol used to make throat lozenges. The water-soluble, biodegradable glassy sugar structures have multiple applications in biomedical engineering, cancer research and device manufacturing.
