A new article in CMAJ (Canadian Medical Association Journal) practical tips for physicians on airplanes who may step in to help in a medical emergency.
What is inside an atom, between the nucleus and the electron? Usually there is nothing, but why could there not be other particles too? If the electron orbits the nucleus at a great distance, there is plenty of space in between for other atoms. A "giant atom" can be created, filled with ordinary atoms. All these atoms form a weak bond, creating a new, exotic state of matter at cold temperatures, referred to as "Rydberg polarons".
AUGUSTA, Ga. (Feb. 26, 2018) - Two distinctive handfuls of short molecules that regulate gene expression have been found in the eye fluid of patients with two distinct types of vision degenerating glaucoma.
These differentially expressed microRNAs point the way toward finding more genes associated with glaucoma, more clues about how these glaucoma types each go about damaging our optic nerve and potential new points of intervention, the scientists say.
MINNEAPOLIS - People who eat vegetables, fruit and whole grains may have lower rates of depression over time, according to a preliminary study released today that will be presented at the American Academy of Neurology's 70th Annual Meeting in Los Angeles, April 21 to 27, 2018.
About 25 percent of older adults admitted to hospitals have dementia and are at increased risk for serious problems like in-hospital falls and delirium (the medical term for an abrupt, rapid change in mental function).
The interplay between surface-water salinity and climate change in Central New York is the subject of a recent paper by researchers in Syracuse University's College of Arts and Sciences.
Kristina Gutchess, a Ph.D. candidate in Earth Sciences, is the lead author of an article in the prestigious journal Environmental Science and Technology (ACS Publications). Her co-authors at Syracuse include Laura Lautz, the Jesse Page Heroy Professor and chair of Earth sciences, and Christa Kelleher, assistant professor of Earth sciences.
Researchers have developed a new way to improve lithium ion battery efficiency. Through the growth of a cubic crystal layer, the scientists have created a thin and dense connecting layer between the electrodes of the battery.
Professor Nobuyuki Zettsu from the Center for Energy and Environmental Science in the Department of Materials Chemistry of Shinshu University in Japan and the director of the center, Professor Katsuya Teshima, led the research.
Leesburg, VA, February 20, 2017 - Emergency patients are too often given head CT to check for skull fractures and brain hemorrhage, leading to unnecessary heath care costs and patient exposure to radiation, according to a study to be presented at the ARRS 2018 Annual Meeting, set for April 22-27 in Washington, DC.
Celiac disease is an autoimmune disorder that affects by some estimates nearly 1 in 100 people. Celiac disease symptoms are triggered by gluten, a protein found in wheat and related plants, but gluten doesn't act alone to cause the digestive symptoms that patients suffer. Rather, gluten induces an overactive immune response when it's modified by the enzyme transglutaminase 2, or TG2, in the small intestine. New research published in the Feb.
The nights in the German federal states („Bundesländer") have been getting brighter and brighter - but not everywhere at the same rate and with one peculiar exemption: light emissions from Thuringia decreased between 2012 and 2017. This is the result of a recent study by scientists Chris Kyba and Theres Küster from the GFZ German Research Centre for Geosciences together with Helga Kuechly from "Luftbild - Umwelt - Planung, Potsdam". Kyba and colleagues published the study in the International Journal of Sustainable Lighting IJSL.
NEW YORK, NY (Feb. 23, 2018) - Single-cell analysis holds enormous potential to study how individual cells influence disease and respond to treatment, but the lack of cost-effective and user-friendly instrumentation remains challenging. As described in a study published today in Nature Communications, researchers at the New York Genome Center (NYGC) and New York University (NYU) have taken steps to facilitate broad access to single-cell sequencing by developing a 3D-printed, portable and low-cost microfluidic controller.
Amidst growing concerns over the low uptake of flu shots in Europe, scientists from the Italian National Research Council and the JRC confirm that vaccinations remain the best way forward when it comes to stopping the spread of infectious diseases.
It's an option that is nearly always more effective than either doing nothing or attempting to contain an outbreak through quarantine.
Harvard researchers have developed a metasurface, comprised of a single planar layer of nanostructures, which exhibits strong optical chirality in transmission. This means it can let circularly polarized light of one polarization pass through almost unhindered, while light of the opposite helicity is completely diffracted away. Such capabilities are incredibly useful for a host of applications, such as circular dichroism spectroscopy in the analysis of drug samples, and polarization filters in telecommunications.
Bottom Line: Ninety-four percent of adolescents ages 13 to 19 in an economically disadvantaged, largely minority population in San Francisco had measurable levels of a biomarker specific for exposure to tobacco smoke (NNAL).
Journal in Which the Study Was Published: Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.
Troy, N.Y. --The world of health care is changing rapidly and there is increased interest in the role that light and lighting can play in improving health outcomes for patients and providing healthy work environments for staff, according to many researchers. Recently, the Center for Lighting Enabled Systems & Applications (LESA) at Rensselaer Polytechnic Institute, together with the Illumination Engineering Society (IES), sponsored a workshop to explore pathways to define and promote the adoption of lighting systems specifically for health-care environments.
