DENVER, Aug. 21, 2024 — Tortilla chips and fresh salsa are tasty in themselves, but they could be even more appealing if you grow the ingredients in a sustainable way. Researchers report that cilantro, bell pepper and jalapeño can be cultivated in recycled glass from discarded, pulverized bottles like those from beer or soda. The pilot study found that partially substituting soil in a planter with recycled glass fragments speeds up plant development and reduces unwanted fungal growth. The researchers will present their results at the fall meeting of the American Chemical Society (ACS). ACS Fall 2024 is ...

The blades of propellers and wind turbines are designed based on aerodynamics principles that were first described mathematically more than a century ago. But engineers have long realized that these formulas don’t work in every situation. To compensate, they have added ad hoc “correction factors” based on empirical observations. Now, for the first time, engineers at MIT have developed a comprehensive, physics-based model that accurately represents the airflow around rotors even under extreme conditions, such as when the blades are operating at high forces and speeds, or are angled in certain directions. The model could improve the way rotors themselves ...

Research Highlights: An analysis based on a proposed heart failure risk prediction tool reveals that the incidence of heart failure may be 2- to 3-fold higher among American Indian adults compared to people in other population groups. The risk prediction equation focused on diabetes control and kidney damage indicates that smoking, Type 2 diabetes, high blood pressure, previous heart attack and diabetes-related kidney damage are associated with increased risk of developing heart failure among American Indian adults. The findings suggest a need to develop population-level preventive strategies in American Indian communities, researchers said. Embargoed until 4 a.m. CT/5 ...

Through deploying the most comprehensive mapping framework, findings indicate overall global flooding could increase by around half between 2020 and the turn ...

In a study published in Applied Psychology, researchers investigated the degree to which people can obtain jobs that fit their interests (called vocational interest fit), with the goal of identifying any differences in fit across race/ethnicity, gender, and education. The study included a diverse sample of more than 250,000 American employees. Overall, employees showed moderate positive vocational interest fit with their jobs. There were small gender differences in vocational interest fit favoring men, especially white and Hispanic men, with minimal differences across other race/ethnicity groups. Considerable differences were observed regarding education, ...

Flexibility exercises are often included in the exercise regimens of athletes and exercisers. New research in the Scandinavian Journal of Medicine & Science in Sports suggests that levels of flexibility may affect survival in middle-aged individuals. After analyzing data on 3,139 people (66% men) aged 46–65 years, investigators obtained a body flexibility score, termed Flexindex. This score was derived from a combination of the passive range of motion in 20 movements (each scored 0–4) involving 7 different joints, resulting in a score range of 0–80. Flexindex was 35% higher in women compared with men. During an average follow-up ...

For the study, 9,725 toddlers were screened at 15-, 18-, or 24-month well child visits using a test called the Modified Checklist for Autism in Toddlers, Revised. Screening results that were positive for autism were most common among children born extremely preterm (51.35%) and least common among those born full-term (6.95%). Subsequent ...

Philadelphia, August 21, 2024 – Childhood obesity can contribute to the development of common immune-mediated skin diseases (IMSDs), such as alopecia areata, atopic dermatitis, and psoriasis, new research finds. Maintaining a healthy weight could potentially help lower the chances of developing these skin conditions. A novel study in the Journal of Investigative Dermatology, published by Elsevier, details the findings of an analysis of 2,161,900 Korean children from 2009 to 2020 to investigate the relationship between obesity or dynamic changes in body weight and the development of IMSDs. IMSDs have detrimental effects on quality of life, including emotional, physical, social, ...

Table salt and refined sugar look white to our eyes, but that is only because their individual colorless crystals scatter visible light. This feature of crystals is not always desirable when it comes to materials for optical and electrical devices, however. Metal-organic frameworks are one such material. Crystalline with micropores, thin films of these nanomaterials have been attracting attention as a next-generation material that could also have an impact on environmental issues such as hydrogen storage and carbon dioxide capture. An Osaka Metropolitan University, Graduate School of Engineering team has found a way to control ...

Organic farming and flower strips promote the health of honey bees. In their vicinity, colonies grow stronger and are generally healthier. This is most likely because the insects have a diverse and continuous food supply there and are less exposed to pesticides. These are the findings of a new study by Martin Luther University Halle-Wittenberg (MLU) and the University of Göttingen, published in the Journal of Applied Ecology. The team analysed data from 32 bee colonies at 16 locations in Germany with different proportions of organic fields, flower strips and semi-natural habitats. According ...

The world is facing an ...

Governments, medical institutions and other bodies require accurate models on health-related matters in order to better organize their activities. Climate change has measurable impacts on society, including on human mortality. However, current models to assess the health impacts of climate change do not account for every environmental parameter, especially humidity, which could influence heat stress perceived by the human body, leaving room for improvement. For the first time, researchers, including those from the University of Tokyo, successfully incorporated humidity data from hundreds of cities into so-called heat stress indicators ...

In brief Extreme weather is leading to more frequent power grid strain and electricity outages. There are a range of regional cooperation agreements among utilities to share electricity. Expanding cooperation areas in the West could cut outage risks by as much as 40%. Expanding cooperation among electricity providers could also help ensure public opinion and policy remain favorable for renewable energy growth. This summer’s Western heat waves raise the specter of recent years’ rotating power outages and record-breaking electricity demand in the region. ...

How do bad bacteria find entry points in the body to cause infection? This question is fundamental for infectious disease experts and people who study bacteria. Harmful pathogens, like Salmonella, find their way through a complex gut system where they are vastly outnumbered by good microbes and immune cells. Still, the pathogens navigate to find vulnerable entry points in the gut that would allow them to invade and infect the body. A team of UC Davis Health researchers has discovered a novel bioelectrical mechanism these pathogens use to find these openings. Their study was ...

Even light smoking of just 1-2 cigarettes a day either before or at any time during pregnancy is significantly associated with major health problems in the newborn, finds research published online in the Journal of Epidemiology & Community Health. The findings add to the evidence indicating that women hoping to become, or who are, pregnant should stub out smoking to protect their newborn’s health, say the researchers. Deaths and serious health issues among newborns have fallen sharply, largely due to improvements in maternity care. But admission ...

Social position—defined by household income and job role—is linked to food delivery preferences in England, suggests an analysis of consumer research published in the open access journal BMJ Public Health. Affluent households are twice as likely as less well off ones to shop online for groceries while households in lower social grades are up to twice as likely to use food delivery apps for take-away meals. And users of these apps are more likely to be living with obesity, the findings indicate. Digital on-demand ...

Twenty minutes of mindful breathing, which focuses a person’s attention on their breath, can rapidly reduce the intensity and unpleasantness of cancer pain and relieve the associated anxiety, suggest the findings of a small comparative study, published online in the journal BMJ Supportive & Palliative Care. Mindful breathing complements traditional pain relief and broadens the repertoire of options available for cancer patients, say the researchers. Moderate to severe pain affects an estimated 30-40% of patients with cancer worldwide, as a result of the tumour compressing or ...
