In the United States, the average American sleeps less than the minimum seven hours of sleep per night recommended by the Center for Disease Control, and nearly half of Americans report negative consequences from insufficient sleep. This problem appears to be especially prevalent in men, who report getting significantly less sleep, on average, than women.
LONDON, ONTARIO - A new study from Lawson Health Research Institute and Western University illustrates how the gut microbiome interacts with an oral medication in prostate cancer patients, suggesting bacteria in the gut play a role in treatment outcomes. The findings, published in Nature Communications, highlight how the drug abiraterone acetate is metabolized by bacteria in the gut to reduce harmful organisms while promoting those that fight cancer.
Scientists at Boston University's National Emerging Infectious Diseases Laboratories (NEIDL) and the Center for Regenerative Medicine (CReM) joined forces to develop the most relevant research model possible for understanding how the coronavirus virus impacts the lungs, by engineering living, "breathing" human lung cells from stem cells for the task.
New research from the University of Georgia supports growing evidence for airborne transmission of COVID-19 in enclosed spaces.
Researchers were able to link a community outbreak of COVID-19 in China to a source patient who likely spread the virus to fellow bus riders through the bus's air conditioning system.
BIRMINGHAM, Ala. - Science has long known that recovery from experimental heart attacks is improved by injection of a mixture of heart muscle cells, endothelial cells and smooth muscle cells, yet results have been limited by poor engraftment and retention, and researchers worry about potential tumorigenesis and heart arrhythmia.
RIVERSIDE, Calif. -- A team of researchers led by biomedical scientist Declan F.
210 scientists from around the world highlight the state of the world's plants and fungi in a landmark Plants, People, Planet Special Issue, in collaboration with the Royal Botanic Gardens, Kew
The Special Issue, 'Protecting and sustainably using the world's plants and fungi', brings together the research - from 210 scientists across 42 countries - behind the 2020 State of the World's Plants and Fungi report, also released today by the Royal Botanic Gardens, Kew.
A new precision drug which stops cancer from repairing its DNA has shown promise in an early-stage clinical trial - highlighting the potential of a new class of drugs known as ATR inhibitors.
The drug candidate, tested in humans for the first time, was shown to be well tolerated and stopped the growth of tumours in over half of patients treated.
Small watery droplets on the edges of blueberry bush leaves are loaded with nutrients for many insects, including bees, wasps and flies, according to a Rutgers-led study, the first of its kind.
The study, published in the journal Proceedings of the Royal Society B: Biological Sciences, suggests that these droplets are an important but underexplored feature in plants, with profound implications for insects in agricultural and natural ecosystems.
It's called senescence, when stressed cells can no longer divide to make new cells, and it's considered a factor in aging and in some diseases. Now scientists have some of the first evidence that at a younger age at least, senescent cells show up quickly after a major injury and are protective.
With implications for the transmission of diseases like COVID-19, researchers have found that ordinary conversation creates a conical 'jet-like' airflow that quickly carries a spray of tiny droplets from a speaker's mouth across meters of an interior space.
PITTSBURGH, Sept. 29, 2020 - A study from the University of Pittsburgh School of Medicine and Cedars-Sinai addresses a mystery first raised in March: Why do some people with COVID-19 develop severe inflammation? The research shows how the molecular structure and sequence of the SARS-CoV-2 spike protein--part of the virus that causes COVID-19--could be behind the inflammatory syndrome cropping up in infected patients.
The research team of INRS (Institut national de la recherche scientifique) Professor Mohamed Mohamedi has designed a green membraneless fuel cell that uses oxygen from the air. The results of this innovative microfluidic application--a first in Canada--were published in Renewable and Sustainable Energy Reviews.
CHICAGO: Hospital resources and infrastructure dedicated to improving quality and safety are essential for achieving safe and high-quality surgical outcomes. A comprehensive review of four key principles of the American College of Surgeons (ACS) Quality Verification Program demonstrates the importance of an overall hospital culture of quality and safety, including top- and mid-level, quality-focused leadership and a committee dedicated to quality improvement.
Philadelphia, September 28, 2020--Researchers at Children's Hospital of Philadelphia (CHOP) and the Perelman School of Medicine at the University of Pennsylvania have identified a cellular pathway that can be targeted with a naturally occurring drug to stimulate lung tissue regeneration, which is necessary for recovery from multiple lung injuries. The findings, which were published today in Nature Cell Biology, could lead to better therapies for patients with lung disease, including acute respiratory distress syndrome (ARDS) due to COVID-19.
