The microbial communities found in glacier and snowpack ecosystems are an essential part of cold weather environments. Chytrids, a group of fungi that include well-known frog pathogens, are often found in abundance in these ecosystems, but culturing these organisms and learning more about their lifecycle, including their relationship to the snow algae found in these environments, has proven challenging. In a recently published paper, researchers revealed that they were able to analyze chytrid DNA from two alpine snowpack sites in Japan using single-spore PCR. The paper was published in Frontiers in Microbiology on June 20. “We have captured the chytrids ...

(LOS ANGELES) – August 29, 2023 - An advancement in 3D bioprinting of native-like skeletal muscle tissues has been made by scientists at the Terasaki Institute for Biomedical Innovation (TIBI). The key to the TIBI scientists’ approach lies in their specially formulated bioink, which contains microparticles engineered for sustained delivery of insulin-like growth factor-1 (IGF-1). As was shown in their recent paper in Macromolecular Bioscience, sustained delivery of IGF-1 enhances the formation of mature skeletal muscle tissue from muscle precursor cells and facilitates their structural alignment. This increases the efficiency of the regenerative process ...

Scientists from the IOCB Prague, the Institute of Physics of the Czech Academy of Sciences, and Palacký University Olomouc, have once again successfully uncovered the mysteries of the world of molecules and atoms. They have experimentally confirmed the correctness of a decades-old theory that assumed a non-uniform distribution of electron density in aromatic molecules. This phenomenon significantly affects the physicochemical properties of molecules and their interactions. This research expands the possibilities for designing new nanomaterials and is the theme of a paper that has just been published in Nature Communications.    The ...

Research Highlights: Adults at risk for heart disease who participated in produce prescription programs for an average of six months increased their consumption of fruits and vegetables and had reduced blood pressure, body mass index and blood sugar levels. Among adults and children, produce prescription programs also appeared to decrease food insecurity — the lack of equitable and stable availability, access, affordability and consumption of healthy foods and drinks — and improve self-reported health status.

Satellite data from across California’s landscapes reveal an increase in nitrogen dioxide levels in remote forest areas, and wildfire and soil emissions are likely the reasons why, according to a paper from University of California, Davis, published today in the journal Environmental Research Letters. Nitrogen dioxide is short-lived in the atmosphere but plays a central role in the formation of the pollutants ozone and particulate matter, which can lead to respiratory issues and asthma in humans, as well as harm plants and crop yields. The researchers looked at summertime surface and satellite concentrations of nitrogen dioxide between 2009 ...

Scientists at UC San Francisco are working on a new approach to treating kidney failure that could one day free people from needing dialysis or having to take harsh drugs to suppress their immune system after a transplant. They have shown for the first time that kidney cells, housed in an implantable device called a bioreactor, can survive inside the body of a pig and mimic several important kidney functions. The device can work quietly in the background, like a pacemaker, and does not trigger the recipient’s immune system to go on the attack. The ...

Several major childhood allergies may all stem from the community of bacteria living in our gut, according to a new study led by researchers at the University of British Columbia and BC Children’s Hospital.  The research, published in Nature Communications, identifies gut microbiome features and early life influences that are associated with children developing any of four common allergies — eczema, asthma, food allergy and/or hay fever. The findings could lead to methods of predicting whether a child will develop allergies, and ways to prevent them from developing at all. “We’re ...

Around the country, non-profits and local governments are testing the idea of food as medicine through “produce prescription programs”—with promising results, according to researchers from the Friedman School of Nutrition Science and Policy at Tufts University. By prescribing free, healthy foods similar to how doctors prescribe medications, clinicians and policy makers hope to remove financial barriers to accessing fruits and vegetables to individuals with diet-related illness. Specifically, produce prescriptions offer vouchers, debit cards, or loyalty cards to access free or discounted produce at grocery retail ...

Reaching the age of 90, 95 or 100, known as exceptional longevity, was more likely for women who maintained their body weight after age 60, according to a multi-institutional study led by University of California San Diego. Older women who sustained a stable weight were 1.2 to 2 times more likely to achieve longevity compared to those who experience a weigh loss of 5 percent or more. Reporting in the Aug. 29, 2023 online issue of the Journal of Gerontology: Medical Sciences, researchers investigated the associations of weight changes later in life with exceptional longevity ...

As global pollution edged upward in 2021, so did its burden on human health, according to new data from the Air Quality Life Index (AQLI). If the world were to permanently reduce fine particulate pollution (PM2.5) to meet the World Health Organization’s (WHO) guideline, the average person would add 2.3 years onto their life expectancy—or a combined 17.8 billion life-years saved worldwide. This data makes clear that particulate pollution remains the world’s greatest external risk to human health, with the impact on life expectancy comparable to that of smoking, more than 3 times that of alcohol use and unsafe water, and more than ...

Fe–S clusters, which are a part of Fe–S proteins, are found across all forms of life. They play a significant role as biological cofactors—helper molecules that assist these proteins in different biochemical transformations—that are involved in respiration and metabolism. These clusters are of keen research interest since they are considered to be a critical part of evolution. They serve as a link between pre-biotic chemistry (chemical processes that existed prior to the emergence of life forms) and the complex molecular and biological systems we know today. Put simply, they ...

The number of women imprisoned in Australia has jumped by 64% in the past decade, leaving thousands of children separated from their mothers and causing huge stress to both parties. In a bid to ease the strain of separation and maintain the mother-child bond, a new prison parenting program has been developed in close collaboration with women in prison as well as prison staff and key members of the Aboriginal community in South Australia. The Mothers Matter program, led by University of South Australia midwife and researcher Belinda Lovell, includes direct input from Aboriginal and/or Torres ...

After a nearly threefold drop in prescriptions for the antibiotic ciprofloxacin between 2015 and 2021, the rates of ciprofloxacin-resistant E. coli bacteria circulating in the community did not decline. In fact, a study of Seattle-area women over age 50 who had not taken any antibiotics for at least a year discovered that the incidence of gut-colonizing ciprofloxacin-resistant E. coli actually increased. About 1 in 5 women in the study were affected. Scientists at the University of Washington School of Medicine, Kaiser Permanente Washington Health Research Institute and Seattle Children’s Hospital ...

National University of Singapore (NUS) physicists have developed a technique to precisely control the alignment of supermoiré lattices by using a set of golden rules, paving the way for the advancement of next generation moiré quantum matter. Moiré patterns are formed when two identical periodic structures are overlaid with a relative twist angle between them or two different periodic structures but overlaid with or without twist angle. The twist angle is the angle between the crystallographic orientations of the two structures. For example, when graphene and hexagonal boron nitride (hBN) which are layered materials are overlaid on each other, the atoms in the ...

A team of clinicians, exercise scientists, pharmaceutical scholars, ethicists and behavioral experts at the University of California, Irvine, outlined their concerns that the use of glucagon-like peptide-1 receptor agonists (GLP-1RAs) to treat childhood obesity and type 2 diabetes may have unintended and adverse consequences for children’s health. The commentary, Unintended Consequences of Glucagon-like Peptide-1 Receptor Agonists Medication in Children and Adolescents – A Call to Action, was published as a perspective in the Journal of Clinical and Translational Science. The article was led by Dan M. Cooper, MD, distinguished professor in the Department of Pediatrics ...

Imagine if you could build an electronic device made entirely of paper. A nontoxic, cost-effective and biodegradable alternative to silicon- and plastic-based components would be a game-changer for a planet quickly filling up with the “e-waste” of discarded gadgets and single-use sensors. That’s the vision of Binghamton University Professor Seokheun (Sean) Choi. He’s worked for years creating better biobatteries that use bacteria or human sweat to generate energy. Some of those batteries have been paper-based, and now he hopes to apply that knowledge to ...

DURHAM, N.C. – Researchers at Duke University have implemented a quantum-based method to observe a quantum effect in the way light-absorbing molecules interact with incoming photons. Known as a conical intersection, the effect puts limitations on the paths molecules can take to change between different configurations. The observation method makes use of a quantum simulator, developed from research in quantum computing, and addresses a long-standing, fundamental question in chemistry critical to processes such as photosynthesis, vision and photocatalysis. It is also an example of ...

Before heading to work each day, most people have spent the night dreaming. Studies show that on any given morning, about 40 percent of the working population recalls their dreams. New research from the University of Notre Dame shows that when dreams are first recalled, people often draw connections between their dreams and waking lives, and the connections they draw alter how they think, feel and act at work. “A Spillover Model of Dreams and Work Behavior: How Dream Meaning Ascription Promotes Awe and Employee Resilience” is forthcoming in the Academy of Management Journal from lead author Casher Belinda, assistant professor ...

In the innovation economy, individuals with STEM PhDs are a critical source of human capital, with nearly 60 percent of PhDs in STEM fields— such as engineering, chemistry and biology—being employed outside of universities. These  students are increasingly contributing to commercial science through patenting. New research from MIT Sloan School of Management and Copenhagen Business School investigated the training of these PhD students to better understand the pipeline and preparation of new inventors.    Conducted by Fiona Murray, MIT Sloan professor and associate dean for Innovation and Inclusion, ...
