Scientists at The Scripps Research Institute report
Professor Richard A. Lerner, M.D., Associate Professor Paul Wentworth, Jr., Ph.D., and a team of investigators at The Scripps Research Institute (TSRI) is reporting that antibodies can destroy bacteria, playing a hitherto unknown role in immune protection. Furthermore, the team found that when antibodies do this, they appear to produce the reactive gas ozone.
“[Ozone] has never been considered a part of biology before,” say
In October, the Upper Atmosphere Research Satellite (UARS) completed the first measurement of the solar ultraviolet radiation spectrum over the duration of an 11 year solar cycle, a period marked by cyclical shifts in the Suns activity. This long measurement record by two instruments aboard UARS will give researchers better insight into how fluctuations in the Suns energy affect ozone and the Earths climate. In turn, the dataset gives scientists tools to document the influence of ma
Scientists open door to possible new treatments for urinary tract infections
Clingy bacteria often spell trouble. Scientists at Washington University School of Medicine in St. Louis have discovered how bacteria manufacture hair-like fibers used to cling to the lining of the kidney and bladder where they cause urinary tract infections (UTIs). The results are published in the Nov. 15 issue of the journal Cell.
“Our findings should lead to new drugs to treat UTIs by blocking t
A research team of the Public University of Navarre (Basque Country), under the supervision of professors Jesus Zurita Gabasa and Jesus Mª Pintor Borobia, from the department of Mechanical, Energetic and Materials Engineering, is working in a project to improve and optimise vibrating tables that are used in the agri-foodstuffs sector. The project is being done by the request of the company Tecnologia Alimentaria Urtasun from Navarre (Basque Country) , manufacturer of this kind of machinery.
A gene may be responsible for halting the spread of cancer through the body, according to scientists at the University of Virginia Health System. The gene, called RhoGDI2, could also be used as a warning to help catch the spread of cancer in patients earlier. A multidisciplinary team of scientists, led by Dr. Dan Theodorescu, professor of urology and molecular physiology at U.Va., used advanced DNA technology to discover that low levels of RhoGDI2 were found more often in invasive cancer than in loca
Bacteria in space, beware. New technology to monitor and identify bacteria is in the works.
Dr. George E. Fox and Dr. Richard Willson, researchers on the National Space Biomedical Research Institute’s immunology and infection team, have developed a new technology to characterize unknown bacteria. Its immediate application will be for identifying bacteria in space, but it will eventually aid in diagnosing medical conditions and detecting biological hazards on Earth.
