"A number of controlled clinical trials — these are carefully designed and conducted scientific studies done in humans — have concluded that cranberry juice really is effective for preventing urinary tract infections," said Terri Anne Camesano, Ph.D., who led the study. "That has important implications, considering the size of the problem and the health care costs involved."
Estimates suggest that urinary tract infections (UTIs) account for about 8 million medical visits each year, at a total cost of more than $1.6 billion. Camesano, who is with the Worcester Polytechnic Institute, said the study set out to shed light on how cranberry juice fights E. coli, the most common cause of UTIs. The study involved growing strains of E. coli in urine collected from healthy volunteers before and after consumption of cranberry juice cocktail. The scientists then tested the E. coli for their ability to stick together and form biofilms. Biofilms are thin, slimy layers that provide an environment for bacteria to thrive.
The scientists concluded that cranberry juice cocktail prevents E. coli from sticking to other bacteria and the surface of a plastic petri dish. E. coli that doesn't stick has a better chance of being flushed out of the urinary track. The results suggest that the beneficial substances in cranberry juice could reach the urinary tract and prevent bacterial adhesion within 8 hours after consumption of cranberry juice.

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.
