TAVR Chugging Along at 5 Years in SURTAVI Trial
Researchers keeping an eye on the long-term outcomes of people undergoing transcatheter aortic valve replacement (TAVR) reported encouraging results in both clinical and economic terms, according to two reports from the Transcatheter Cardiovascular Therapeutics (TCT) meeting. The 5-year incidence of all-cause mortality or disabling stroke among people in the SURTAVI trial was no different between […]
Using microbes to make carbon-neutral fuel
Researchers at Washington University in St. Louis have discovered a new way to train microbes to make a readily usable biofuel. A team of biologists and engineers modified a microbe called Rhodopseudomonas palustris TIE-1 (TIE-1) so that it can produce a biofuel using only three renewable and naturally abundant source ingredients: carbon dioxide, solar panel-generated […]
Cleveland Clinic study links gut microbiome and aggressive prostate cancer: Researchers uncover how diet, lifestyle modifications may lower risk of lethal disease
Cleveland Clinic researchers have shown for the first time that diet-associated molecules in the gut are associated with aggressive prostate cancer, suggesting dietary interventions may help reduce risk. Findings from the study were published in Cancer Epidemiology, Biomarkers & Prevention. While more research will be necessary, the study’s lead author Nima Sharifi, M.D., says findings […]
Evacuation during and after the 2018 Montecito debris flow
A new study by UC Santa Barbara researchers speaks to the importance of public awareness programs in keeping residents — and emergency management offices — informed about rare but potentially lethal natural events in their area. The paper, co-authored by geology professor Ed Keller and colleagues Summer Gray, an assistant professor of environmental studies, Keith […]
Beyond childhood: Picky eating in college students
Looking beyond the picky eating of childhood, researchers looked at this behavior in college students. Self-identified picky eaters ate significantly less fiber and vegetables and reported greater levels of social phobia than non-picky eaters, according to a new study in the Journal of Nutrition Education and Behavior, published by Elsevier. Social phobia is the fear […]
A ‘cousin’ of Viagra reduces obesity by stimulating cells to burn fat
Researchers at Johns Hopkins Medicine have found that a drug first developed to treat Alzheimer’s disease, schizophrenia and sickle cell disease reduces obesity and fatty liver in mice and improves their heart function — without changes in food intake or daily activity. These findings, published online Oct. 7 in the Journal of Clinical Investigation, reveal […]
Microbiology research furthers understanding of ocean’s role in carbon cycling
Microbiology researchers at Oregon State University have shed new light on the mechanisms of carbon cycling in the ocean, using a novel approach to track which microbes are consuming different types of organic carbon produced by common phytoplankton species. The research is an important step toward forecasting how much carbon will leave the ocean for […]
Scientists capture the fleeting transition of water into a highly reactive state: It’s the first direct observation of a hydroxyl-hydronium complex – important for a wide range of chemical and biological processes from the tails of comets to cancer treatment
Researchers at the Department of Energy’s SLAC National Accelerator Laboratory have uncovered a key step in the ionization of liquid water using the lab’s high-speed “electron camera,” MeV-UED. This reaction is of fundamental significance to a wide range of fields, including nuclear engineering, space travel, cancer treatment and environmental remediation. Their results were published in […]
Two-dimensional hybrid metal halide device allows control of terahertz emissions
Researchers have utilized two-dimensional hybrid metal halides in a device that allows directional control of terahertz radiation generated by a spintronic scheme. The device has better signal efficiency than conventional terahertz generators, and is thinner, lighter and less expensive to produce. Terahertz (THz) refers to the part of the electromagnetic spectrum (i.e., frequencies between 100 […]
Early accumulation of tau in the brain predicts memory decline in Alzheimer’s disease
Researchers at Karolinska Institutet in Sweden have compared how well different Alzheimer’s biomarkers predict the progression of the disease and its effect on the memory. They found that early accumulation of tau proteins in the brain as measured by PET scanner was more effective at predicting memory impairment than biomarkers in the cerebrospinal fluid or […]
