The esophagus isnt merely a tube for food traveling from the mouth to the stomach, it also provides an environment for bacteria to live, according to a new study by NYU School of Medicine scientists that overturns the general belief that the esophagus is free of bacteria.
"People thought that the esophagus wasnt hospitable to bacteria," says Martin J. Blaser, M.D., Frederick King Professor and Chairman of the Department of Medicine, and Professor of Microbiology, an author of the study. Bacteria were believed to move through the esophagus, the tube connecting the mouth to the stomach, as food-borne passengers on route to the stomach.
But the new study in the March 23 print issue of the Proceedings of the National Academy of Sciences demonstrates that bacteria do indeed live in the esophagus, and these microbes are a diverse bunch. "This study provides evidence for the first time that there are indigenous microbes in the human esophagus," says Zhiheng Pei, M.D., Ph.D., Assistant Professor of Pathology and Medicine, the studys lead author.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
