AMHERST, Mass. – The global demand for palm oil—the most widely consumed vegetable oil on the planet, in everything from instant noodles to lipstick—is driving worldwide tropical deforestation. While many studies have shown the loss of biodiversity when rainforests are converted to oil palm plantations, researchers at the University of Massachusetts of Amherst are the first to show far-reaching and wide-ranging disturbances to the watersheds in which such plantations occur. Because many Indigenous peoples rely on water downstream from the plantations for their daily needs, the marked decrease in water quality has ...

A research team at Pitt led by Alexander Star, a chemistry professor in the Kenneth P. Dietrich School of Arts and Sciences, has developed a fentanyl sensor that is six orders of magnitude more sensitive than any electrochemical sensor for the drug reported in the past five years. The portable sensor can also tell the difference between fentanyl and other opioids. Their work was published in the journal Small. Fentanyl is a synthetic opioid and one of the main drivers in overdose deaths in the United States, Star said. It’s often mixed with other drugs, but because ...

Scientists at the Department of Energy’s Oak Ridge National Laboratory have developed lubricant additives that protect both water turbine equipment and the surrounding environment. Each year, roughly 2.47 billion gallons of lubricating oil are consumed in the United States alone for engines and industrial machinery, according to DOE, with about half eventually finding its way into the environment. While environmentally acceptable lubricants are available, they are not optimized with additives that can greatly improve performance while posing minimal environmental impact if accidentally released. To create nontoxic, biodegradable and high-performing lubricant ...

Before the patient underwent CMR, optical pumped magnetometer magnetocardiography (OPM-MCG) revealed abnormalities characteristic ...

https://www.scienceopen.com/hosted-document?doi=10.15212/CVIA.2024.0026 Announcing a new article publication for Cardiovascular Innovations and Applications journal. Heart Failure (HF) is one of the leading problems in cardiology practice today. Acute decompensated heart failure (ADHF) is a significant cause of mortality and morbidity worldwide, and this is more relevant in the Asian subcontinent with a high population burden. Various regional registries in Asia have given us valuable insight into the aetiology and outcomes in this context. Though there are regional differences, it is clear from the review carried out in this paper that HF affects a much younger population. ...

An article published in The Faseb Journal describes a Brazilian study analyzing the correlation between two key energy metabolism regulation processes: the absorption and release of calcium ions by mitochondria, the organelles that generate energy for cells; and autophagy induced by calorie restriction. Autophagy occurs when cells break down and reuse their own cytoplasm. The study was conducted at the Center for Research on Redox Processes in Biomedicine (Redoxome), a Research, Innovation and Dissemination Center (RIDC) funded by FAPESP and hosted by the University of São Paulo’s Institute of Chemistry ...

Consistent adherence to physical activity guidelines throughout middle-age is associated with a higher health-related quality of life in women, according to a new study publishing May 2nd in the open-access journal PLOS Medicine by Binh Nguyen of University of Sydney, Australia, and colleagues. The evidence for an association between physical activity and health-related quality of life has been based primarily on cross-sectional studies and short-term randomized controlled trials. Few longitudinal studies have measured physical activity at more than one time point and examined the long-term causal effects ...

In experiments in isolated villages in Honduras, researchers evaluated a new strategy for identifying individuals that could be targeted for effective information spreading. Their approach – more effective than random targeting, and also less time-requisite than approaches that require a complete understanding of the relevant social network – could have far-reaching policy implications in lower and middle-income countries. Understanding the structure and function of human social networks has yielded insights for exploiting social ...

Chromosomal 22q11.2 deletions increase risk for meningomyelocele,  one of the most severe and common forms of spina bifida, researchers report. According to the findings, this risk is mediated by the loss of Crkl, one of several neural tube expressed genes located on the 22q11.2 deletion interval, and this risk is only partially alleviated by folate supplementation. Meningomyelocele (MM) is a severe type of neural tube defect, which often requires pre- or post-natal surgical repair and can result in a variety of physical and developmental difficulties. Although the incidence of the condition has declined in recent decades, largely due to folic acid (FA) fortification, MM ...

Molecular circadian clocks in the brain and muscle tissue cooperate to keep muscles healthy and functioning daily, according to a new study in mice. The findings could provide valuable insight into understanding the roles of circadian disruption in age-associated health issues and potential strategies to protect muscle function in aging individuals. A circadian molecular clock network is crucial for daily physiology and maintaining health. It’s thought that this network – which extends throughout all cells in the body – is hierarchically organized and coordinated by the brain’s suprachiasmatic nucleus (SCN), which receives daily light cues and synchronizes ...

Early care and education (ECE) programs – like Pre-Kindergarten (Pre-K) and Head Start – are widely regarded as effective public investments for reducing income- and race-based achievement gaps and helping children succeed in school with impacts extending well into adulthood. However, in a Policy Forum, Margaret Burchinal and colleagues present recent evidence suggesting that preschool impacts are not unequivocally positive and the science on the overall outcomes of these programs remains unsettled. According to Burchinal et al., more rigorous research is needed to understand how to design early education programs that produce long-term positive ...

Precisely measuring the energy states of individual atoms has been a historical challenge for physicists due to atomic recoil. When an atom interacts with a photon, the atom “recoils” in the opposite direction, making it difficult to measure the position and momentum of the atom precisely. This recoil can have big implications for quantum sensing, which detects minute changes in parameters, for example, using changes in gravitational waves to determine the shape of the Earth or even detect dark matter.  In a new paper published in the Science, JILA and NIST Fellows Ana Maria Rey and James Thompson, ...

A new catalyst made from an inexpensive, abundant metal and common table sugar has the power to destroy carbon dioxide (CO2) gas. In a new Northwestern University study, the catalyst successfully converted CO2 into carbon monoxide (CO), an important building block to produce a variety of useful chemicals. When the reaction occurs in the presence of hydrogen, for example, CO2 and hydrogen transform into synthesis gas (or syngas), a highly valuable precursor to producing fuels that can potentially replace gasoline.  With recent advances in carbon capture technologies, post-combustion carbon capture is ...
