HOUSTON - (Sept. 9, 2019) - It only took the replacement of one atom for Rice University scientists to give new powers to biocompatible fluorescent molecules.
The Rice lab of chemist Han Xiao reported in the Journal of the American Chemical Society it has developed a single-atom switch to turn fluorescent dyes used in biological imaging on and off at will.
The technique will enable high-resolution imaging and dynamic tracking of biological processes in living cells, tissues and animals.
Our global food production system uses 53 million tonnes of phosphate fertilizers annually, processed from 270 million tonnes of mined phosphate rock . Estimates show up to 90% phosphate loss from mine to fork . A considerable part of this loss is phosphate pollution in water, some of which creates "dead zones", areas where little or no marine life can survive. With an increase in food demand by 60% towards 2050 , our food production system will need even more phosphate fertilizers. But where do the fertilizers come from and where do they go?
Epidemiological studies rely heavily on survey research; however, limitations of traditional data collection methods - paper-based, in-person, phone, mail, and internet surveys - can serve as barriers to recruitment and retention of research participants. Conventional data collection methods are especially ineffective for aging minority populations, who may have limited English proficiency and less access to and facility with technology.
CHAMPAIGN, Ill. -- If you want something done, ask a busy person - or so the saying goes. According to a new paper co-written by a University of Illinois scholar who studies attitudes and persuasion psychology, if you want to sell something quickly, it helps to try a busy consumer.
Tel Aviv University and Sheba Medical Center researchers say they have discovered why more than half of patients with metastatic melanoma do not respond to immunotherapy cancer treatments.
Scientists from the School of Medicine, Trinity College Dublin, have, for the first time, discovered a family of proteins that are associated with lower blood sugar levels among obese patients with type 2 diabetes.
The periodic table of elements was proposed in 1869, and thereafter became one of the cornerstones of the natural sciences. This table was designed to contain all the elements (atoms) found in nature in a special layout that groups them in rows and columns according to one of their most important characteristics, the number of electrons. Scientists have used the periodic table for decades to predict the characteristics of the then-unknown elements, which were added to the table over time.
Washington, D.C. (September 9, 2019) - Food insecurity -- uncertainty about or a lack of consistent access to food that meets the needs of household members -- is a persistent social problem in the United States that affected roughly 14.3 million households in 2018 and nearly 14% of households with children, according to the U.S. Department of Agriculture.
EVANSTON, Ill. -- The final chapter of the historic detection of the powerful merger of two neutron stars in 2017 officially has been written. After the extremely bright burst finally faded to black, an international team led by Northwestern University painstakingly constructed its afterglow -- the last bit of the famed event's life cycle.
Not only is the resulting image the deepest picture of the neutron star collision's afterglow to date, it also reveals secrets about the origins of the merger, the jet it created and the nature of shorter gamma ray bursts.
Filial piety - the traditional value of caring for one's elders - is central to the Chinese concept of family and has long shaped intergenerational relationships, daily life, and well-being, for older Chinese adults. The intersection of Eastern values and Western norms, however, can alter cultural beliefs across generations and negatively impact aging Chinese immigrants' physical and mental health and the caregiving burdens faced by their children, according to two new Rutgers studies.
WORCESTER -- Research from the lab of Mark Alkema, PhD, professor of neurobiology, sheds light on how the "flight-or-flight" response impairs long-term organism health. The study, conducted in the nematode worm, C. elegans, a common research model, was published in Nature.
Barcelona-- The largest stratified medicine dataset of non-small cell lung cancer patients indicates further molecular stratifications could benefit from targeted therapies, according to research presented today at the IASLC 2019 World Conference on Lung Cancer, hosted by the International Association for the Study of Lung Cancer.
There is good news on the infection front: infections acquired by patients in Canadian hospitals are declining, with a 30% reduction between 2009 and 2017, according to new research in CMAJ (Canadian Medical Association Journal). However, continued focus is necessary to identify and prevent emerging antimicrobial-resistant pathogens, and infections with medical devices, such as urinary or intravenous catheters.
A comprehensive new Canadian guideline provides practical guidance for physicians, allied health professionals, patients and families on managing Parkinson disease, based on the latest evidence. The guideline is published in CMAJ (Canadian Medical Association Journal), accompanied by an easy-to-reference infographic and podcast.
Parkinson disease is a debilitating, progressive neurological condition that affects quality of life for patients and their caregivers.
In a systematic review, researchers identified three characteristics of case management programs that consistently yielded positive results: case selection for frequent users with complex problems, high-intensity case management interventions and a multidisciplinary care plan. This review included data from 20 studies, 17 of which were quantitative, of adult frequent users with chronic diseases in primary, secondary and tertiary care settings. Case management was delivered in a primary care setting in all of the studies.
