With more of us living longer, driving is becoming increasingly important in later life, helping us to stay independent, socially connected and mobile.
But driving is also one of the biggest challenges facing older people. Age-related problems with eyesight, motor skills, reflexes, and cognitive ability increase the risk of an accident or collision and the increased frailty of older drivers mean they are more likely to be seriously injured or killed as a result.
Estimates are that roughly 1 percent of people in Western countries may have bile acid diarrhea, including patients with Crohn's disease, ileal resection, diarrhea-predominant irritable bowel syndrome (IBS-D), and chronic functional diarrhea. Current management for bile acid diarrhea has demonstrated limited efficacy, with some therapies producing significant side effects. A recent study published in The FASEB Journal explored the efficacy of CFTR (cystic fibrosis transmembrane conductance regulator) inhibition to reduce excessive secretion in the colon due to bile acids.
PROVIDENCE, R.I. [Brown University] -- DNA molecules are well known as carriers of huge amounts of biological information, and there is growing interest in using DNA in engineered data storage devices that can hold vastly more data than our current hard drives. But new research shows that DNA isn't the only game in town when it comes to molecular data storage.
A joint Australian-Indian 18-year study made possible by the recruitment, diagnosis, and the DNA screening of thousands of people in India has identified a new clue in the quest for causes of schizophrenia, and for potential treatments.
A collaboration between The University of Queensland (UQ) and a team of Indian researchers led by Professor Rangaswamy Thara, co- founder and director of the Schizophrenia Research Foundation in Chennai, searched the genomes of more than 3000 individuals and found those with schizophrenia were more likely to have a particular genetic variation.
Sure, computers can be used to play grandmaster-level chess (chess_computer), but can they make scientific discoveries? Researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have shown that an algorithm with no training in materials science can scan the text of millions of papers and uncover new scientific knowledge.
Research led by the University of Birmingham has found important new ways that the BRCA1 gene functions which could help develop our understanding of the development of ovarian and breast cancers.
The research, published in Nature today (July 3rd), was led by experts at the University of Birmingham's Birmingham Centre for Genome Biology and Institute of Cancer and Genomic Sciences and is part of a five-year research project which is playing a pivotal role in identifying and understanding breast cancer genes.
A study by Stanford University School of Medicine investigators has revealed that immune cells infiltrate the rare newborn nerve-cell nurseries of the aging brain. There's every reason to think those interlopers are up to no good. Experiments in a dish and in living animals indicate they're secreting a substance that chokes off new nerve cell production.
CAMBRIDGE, MA -- In any conventional silicon-based solar cell, there is an absolute limit on overall efficiency, based partly on the fact that each photon of light can only knock loose a single electron, even if that photon carried twice the energy needed to do so. But now, researchers have demonstrated a method for getting high-energy photons striking silicon to kick out two electrons instead of one, opening the door for a new kind of solar cell with greater efficiency than was thought possible.
From time to time, there have been long periods of cooling in Earth's history. Temperatures had already fallen for more than ten million years before the last ice age began about 2.5 million years ago. At that time the northern hemisphere was covered with massive ice masses and glaciers. A geoscientific paradigm, widespread for over twenty years, explains this cooling with the formation of the large mountain ranges such as the Andes, the Himalayas and the Alps. As a result, more rock weathering has taken place, the paradigm suggests.
BOSTON - (July 3, 2019) - Researchers at Joslin Diabetes Center have shown that a protein found in the eye can protect against and potentially treat diabetic eye disease. At high enough levels, Retinol Binding Protein 3 (or RBP3) prevents the development of diabetic retinopathy. If introduced early enough in the development of the disease, RBP3 was shown to reverse the effects of the complication in rodent models of diabetes. These results are reported today in Science Translational Medicine.
Perfumes that use the most popular scents do not always obtain the highest number of ratings, according to an analysis of online perfume reviews.
A study of 10,000 perfumes and their online ratings reveals which odours are likely to bring success, with some surprising combinations providing a boost to ratings.
The Global Precipitation Measurement mission or GPM core satellite passed over the storm and measured the rate in which rain was falling throughout it.
The GPM core satellite passed over Hurricane Barbara at 3:21 a.m. EDT (0721 UTC) on July 3, 2019. GPM found the heaviest rainfall rates were occurring around the eye. There, rain was falling at a rate of more than 50 mm (2 inches) per hour. GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency, JAXA.
Not all burning mouths are the result of a medical condition known as "burning mouth syndrome" (BMS) and physicians and researchers need better standards for an appropriate diagnosis, according to new research at the School of Dental Medicine at Case Western Reserve University.
BMS is a painful, complex condition associated with a chronic or recurring burning, scalding or tingling feeling in the mouth--sometimes accompanied by a metallic taste or dry mouth sensation.
The question of how to best adapt to extreme climate is a critical issue facing modern societies worldwide. In "The Role of Diet in Resilience and Vulnerability to Climate Change among Early Agricultural Communities in the Maya Lowlands," published in Current Anthropology, authors Claire Ebert, Julie Hoggarth, Jaime Awe, Brendan Culleton, and Douglas Kennett examine the role of diet in the ability of the ancient Maya to withstand periods of severe climatic stress.
New findings show that old-growth forests, a critical nesting habitat for threatened northern spotted owls, are less likely to experience high-severity fire than young-growth forests during wildfires. This suggests that old-growth forest could be leveraged to provide valuable fire refuges that support forest biodiversity and buffer the extreme effects of climate change on fire regimes in the Pacific Northwest.
