New findings on long COVID — long-term effects on health experienced by many who have had COVID-19 — present a good-news, bad-news situation, according to a study at Washington University School of Medicine in St. Louis and the Veterans Affairs St. Louis Health Care system. The bad news: COVID-19 patients who were hospitalized within the first 30 days after infection face a 29% higher risk of death in the third year compared with people who have not had the virus. However, the three-year death risk still marks a significant decline compared with such risk at the one- and two-year marks post-infection. The findings also show that even people with mild COVID-19 were still ...

Osaka, Japan – The compound of iron and aluminum with the chemical formula Fe3Al has some very useful mechanical properties. A team from Osaka University has combined simulations with experimental techniques to better understand the kinetics of the formation of microstructures to enhance and utilize these properties and how to harness them for specific applications. In a study recently published in Acta Materialia, the researchers took an in-depth look at the way the microstructure of Fe3Al develops because the ordered domains that form contribute to one of its key properties: superelasticity. When high loads are applied to superelastic materials they ...

COLLEGE PARK, Md. – In a head-to-head comparison of masks worn by people with active COVID-19, the inexpensive “duckbill” N95 came out on top, stopping 98% of COVID-19 particles in the breath of infected people from escaping into the air. Led by researchers from the University of Maryland School of Public Health (SPH), results showed other masks also performed well, blocking at least 70% of viral particles from escaping from the source – an infected person’s exhaled breath. The study, Relative efficacy of masks and respirators as source control for viral aerosol shedding from people infected with SARS-CoV-2, published May 29 in eBioMedicine, a Lancet ...

Cultivating creativity in schools is vital for a future driven by artificial intelligence (AI). But while teachers embrace creativity as an essential 21st century skill, a lack of valid and reliable creativity tests means schools struggle to assess student achievement.   Now, a new machine-learning model developed by the University of South Australia is providing teachers with access to high-quality, fit-for-purpose creativity tests, that can score assessments in a fraction of the time and a fraction of the cost.   Applied to the current ...

The deep degradation of organic pollutants through solar light-coupled photocatalysis and the Fenton reaction (Photo-Fenton) holds significant importance in the field of water purification. In this study, a novel bifunctional catalyst (Fe-PEI-CN) was synthesized by electrostatic self-assembly and hydrothermal methods, doping graphene-like carbon nitride (CN) with polyethyleneimine (PEI) and iron (Fe) species. This catalyst efficiently degraded p-chlorophenol (p-ClPhOH) by generating hydrogen peroxide (H2O2) during the photocatalytic process. The relationship between catalytic efficiency and structure was explored using various characterization techniques.Under ...

Tumour protein P53 (TP53) plays an important role in suppressing the growth of tumours. Mutations in the gene for TP53 can have a disastrous effect, hampering the body's ability to fight tumours and even encouraging their growth. Because these are the most common mutations in cancers, TP53 has long been an interesting therapeutic target. However, efforts to destroy the mutant protein have been hampered by the difficulty of finding a way to bind to it. Now, a team of researchers from Xi'an ...

New Curtin University research reveals taking pictures of food isn’t just content for our social media feeds, but could be the key to improving people’s diets.   Published in the prestigious American Journal of Clinical Nutrition, the feeding study saw researchers measure the weight of meals, which were then provided to participants over a day for breakfast, lunch and dinner.   Participants compared different technology-assisted methods to recall what they had eaten over the past 24 hours.    One method asked participants to take photos of their meals using the mobile Food Record app.   These ...

On-site pathology tests for infectious diseases in rural and remote locations can be just as reliable and accurate as tests carried out in a hospital laboratory, a new report from Flinders University shows. Flinders University researchers tested the quality of on-site pathology testing, or Point-of-Care-Testing (POCT), for molecular-based, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) detection in over 100 remote Aboriginal and Torres Strait Islander communities across Australia. “Our study demonstrates that when point-of-care testing models are effectively established and managed, the quality of pathology results can be equivalent to ...

STARKVILLE, Miss.— A Mississippi State faculty member’s work on symbiosis—a mutually beneficial relationship between living organisms—is pushing back against the newer theory of a “single-origin” of root nodule symbiosis (RNS)—that all symbiosis between plant root nodules and nitrogen-fixing bacteria stems from one point—instead suggesting a “multiple-origin” theory of symbiosis which opens a better understanding for genetically engineering crops. Ryan A. Folk, an assistant professor in the MSU Department of Biological Sciences and herbarium curator, is an author on a paper published this month in Nature ...

Shortly after artificial intelligence models including Midjourney and OpenAI’s Dall-E went public, AI-generated art started winning competitions: one in digital art, another in photography. Concern rumbled that AI could replace artists — and even, by some metrics, be more creative than humans. But simultaneously, people were exploring these tools as ways to augment their creative processes, not replace them. University of Washington researchers grew curious about how AI might affect creativity in children, specifically, so they worked with a group of 12 Seattle-area kids ages seven to 13 to explore how the kids’ creative processes interacted ...

In a paper recently published in Nature Communications, the HUN-REN-ELTE Protein Modeling Research Group (Institute of Chemistry) has laid the foundations for a mathematical method, allowing the computer-assisted comparison of the three-dimensional structures of proteins. The method is unique in that while the alternatives available so far only took into account the position of the atoms, the new technique, called LoCoHD (Local Composition Hellinger Distance), also includes the chemical information of the atoms. Proteins are molecular machines that carry out processes necessary for cells to function, acting as molecular switches, transcribing information ...

When trying to measure molecular structures with nanometer precision, every bit of noise shows up in the data: someone walking past the microscope, tiny vibrations in the building and even the traffic outside. A new processing technique removes noise from optical microscope data in real time, allowing scientists to track individual molecules over 10 times more precisely than was possible before. A team of bioengineering researchers at the University of Illinois Urbana-Champaign has introduced an algorithm called adaptive intersection maximization, or AIM, that removes high-frequency ...

Researchers at Rice University have revealed a previously unknown function of opioid receptors in the development of the enteric nervous system (ENS), often referred to as the “brain in the gut.” This discovery challenges conventional understanding of opioid receptors, shedding new light on their significance beyond pain management and addiction. Led by Rosa Uribe, an assistant professor of biosciences at Rice and a Cancer Prevention and Research Institute of Texas (CPRIT) Scholar, the research team identified the genes critical for ENS development by conducting a series of experiments using zebrafish ...

CLEVELAND - Researchers from Cleveland Clinic and IBM recently published findings in the Journal of Chemical Theory and Computation that could lay the groundwork for applying quantum computing methods to protein structure prediction. This publication is the first peer-reviewed quantum computing paper from the Cleveland Clinic-IBM  Discovery Accelerator partnership.  For decades, researchers have leveraged computational approaches to predict protein structures. A protein folds itself into a structure that determines how it functions and binds to other ...

WHAT: Researchers have, for the first time, visualized the full network of blood vessels across the cortex of awake mice, finding that blood vessels rhythmically expand and contract leading to “waves” washing across the surface of the brain. These findings, funded by the National Institutes of Health (NIH), improve the understanding of how the brain receives blood, though the function of the waves remains a mystery. A network of elastic and actively pumping vessels carrying oxygenated blood span the surface of the brain before entering the cortex. There, they feed into a second network of capillaries that supply oxygen deeper into ...

More out-of-state women, largely from Texas and Alaska, are traveling to Washington state to obtain an abortion than was the case before the U.S. Supreme Court struck down the constitutional right to abortion, according to research published today in JAMA Network Open. The study tracked the number of abortions performed at the Cedar River Clinics, a large network of care sites in Washington state, both before and after the 2022 Dobbs decision. Researchers found a 50% increase in out-of-state patients (from 4% to 6%) and documented an average one-week delay in care for all patients seeking ...

SAN ANTONIO (May 29, 2024) – SARS-CoV-2, the virus that causes COVID-19 disease, continues to evolve and evade current vaccine and therapeutic interventions. A consortium of scientists at Texas Biomedical Research Institute (Texas Biomed), the University of Alabama at Birmingham (UAB) and Columbia University have developed a promising new human monoclonal antibody that appears a step closer to a universal antibody cocktail that works against all strains of SARS-CoV-2. “This antibody worked against the original SARS-CoV-2 strain, Omicron and SARS-CoV, providing ...
