Knowledge gaps on opioid use after surgery offer opportunities for improving patient education
Researchers at Hospital for Special Surgery (HSS) have identified gaps in patient knowledge about pain management and opioid use before total hip replacement, including misconceptions about how much pain relief to expect from opioids after surgery, how to use multiple modes of pain relief (multimodal analgesia) safely and effectively, and proper opioid storage and disposal. These findings were presented at the 2021 Spring American Society of Regional Anesthesia and Pain Medicine (ASRA) Annual Meeting.

University of Cincinnati researcher says proteins in patients biomarkers of heart disease
Donald Lynch Jr., MD, will be presenting preliminary research at the American College of Cardiology on Saturday, May 15, that suggests plasma proteins discovered in the blood samples of diabetic patients who went on to develop obstructive coronary disease (OCAD) may serve as biomarkers of severe heart blockage.

Study finds low sugar metabolite associates with disability, neurodegeneration in MS
A new University of California, Irvine-led study finds low serum levels of the sugar N-acetylglucosamine (GlcNAc), is associated with progressive disability and neurodegeneration in multiple sclerosis (MS).

The Achilles heel of the coronavirus
SARS-CoV-2 is critically dependent on a special mechanism for the production of its proteins. A collaborative team led by a research group at ETH Zurich obtained molecular insights into this process and demonstrated that it can be inhibited by chemical compounds, thereby significantly reducing viral replication in infected cells.

A new approach to identify genetic boundaries of species could also impact policy
A new approach to genomic species delineation could impact policy and lend clarity to legislation for designating a species as endangered or at risk. Evolutionary biologists model the process of speciation, which follows population formation, improving on current species delineation methods.

Victoria's watch catchments may not recover from drought: Study
Australian-first research by Monash University discredits the theory that rivers and underground water supplies eventually replenish following droughts or floods. Following the Australian Millennium Drought, one-third of Victoria's water catchments still had not recovered from drought nearly eight years later.For those water catchments not recovered, roughly 80 per cent showed no evidence of recovering anytime soon.

Researchers identify a missing piece of the Lyme disease puzzle
"This discovery furthers our understanding of how Borrelia burgdorferi causes inflammation and disease," said Mari Davis, who is the lead author on the paper, a former master's graduate of the Jutras lab in the Department of Biochemistry in the College of Agriculture and Life Sciences. "It is a testament to how unique that this bacterium is -- and how we need to keep working to understand more about what is going on behind the scenes in order to develop future diagnostics and treatments."

Ventilation in buildings: where water sanitation was in the 1800s
A group of the world's leading experts in the transmission of airborne pathogens is calling for a tightened regulatory system to control air quality in buildings - as a way of reducing the spread of covid-19 and other illnesses.

Brain mechanism of curiosity unraveled
Researchers from the Netherlands Institute for Neuroscience have discovered a new brain circuit underlying curiosity and novelty seeking behavior. Using several innovative techniques, a whole path of multiple brain regions was uncovered that converts curiosity into action in mice. The results were published in Science.

What makes plant cell walls both strong and extensible?
A plant cell wall's unique ability to expand without weakening or breaking is due to the movement of its cellulose skeleton, according to new research that models the cell wall. The new study, by Penn State researchers, presents a new concept of the plant cell wall, gives insights into plant cell growth, and could provide inspiration for the design of polymeric materials.

To prevent next pandemic, scientists say we must regulate air like food and water
Humans in the 21st century spend most of their time indoors, but the air we breathe inside buildings is not regulated to the same degree as the food we eat and the water we drink. A group of 39 researchers from 14 countries, including two from the University of Colorado Boulder, say that needs to change to reduce disease transmission and prevent the next pandemic.

After the rains return, watersheds may not always recover from drought
Challenging the assumption that watershed streamflow always recovers from drought, a new study done seven years after the "Millennium Drought," the worst drought ever recorded in southeastern Australia, reports that more than a third of the region's affected watersheds had not yet recovered.

Making AI algorithms show their work
An AI neural network built to predict protein and RNA sequence interactions cannot explain what patterns it sees. CSHL Assistant Professor Peter Koo found a way to "quiz" the network with a carefully designed set of synthetic RNA sequences to find out what it learned. The answer was a little surprising.
