In a randomized, controlled study published online in the journal, Nutrients, researchers found that including mixed tree nuts in a weight management program resulted in significant weight loss and improved satiety.

In its latest clinical practice guideline on community-acquired pneumonia the American Thoracic Society's guidelines panel addresses the use of nucleic acid-based testing for non-influenza viral pathogens. The guideline was published online in the May 1 issue of the American Journal of Respiratory and Critical Care Medicine. An explainer video may be viewed here.

Sudhir Kumar's team reconstructed the genome of the SARS-CoV-2 progenitor and its early pedigree from a dataset of coronavirus genomes. They found the SARS-CoV-2 progenitor was already circulating with an earlier timeline, at least 6 to 8 weeks prior to the first genome sequenced in China. They have also developed an intuitive mutational fingerprint and Greek symbol classification categorization system of the major strains, sub-strains and variants infecting an individual or colonizing a global region.

Nearly one in five older adults say their mental health has gotten worse since the pandemic began in March 2020, and an equal percentage say their sleep has suffered in that time too. More than one in four say they're more anxious or worried than before the COVID-19 era, according to a new poll of people age 50 to 80. But the poll also reveals hopeful signs that many older adults are showing long-term resilience.

Researchers from Osaka University find a phenomenon of reciprocating propagation of laser pulse intensity in free space.

A meta-analysis of 14 air pollution studies from around the world found that exposure to high levels of air pollutants during childhood increases the likelihood of high blood pressure in children and adolescents, and the risk of hypertension later in life.A special publication on air pollution features several studies focused on the relationship between ambient air pollution with cardiovascular risk factors such as hypertension.

Small changes in the structure of DNA have been implicated in breast cancer and other diseases, but they've been extremely difficult to detect -- until now. Using what they describe as a "chemical nose," UC Riverside chemists are able to "smell" when bits of DNA are folded in unusual ways.

The climate action potential of carbon capture during the processing of biomass feedstock is considerable, ETH Zurich researchers have calculated. If this potential is to be fully exploited in practice, however, there are challenges to overcome.

In a recent article in Sustainability, scientists from Reykjavik University (RU), the University of Gothenburg, and the Icelandic Meteorological Office describe their finding of microplastic in a remote and pristine area of Vatnajokull glacier in Iceland, Europe's largest ice cap. Microplastics may affect the melting and rheological behaviour of glaciers, thus influencing the future meltwater contribution to the oceans and rising sea levels.

New Edith Cowan University (ECU) research has found that by eating just one cup of nitrate-rich vegetables each day people can significantly reduce their risk of heart disease.

New research, led by Durham University and published in the journal Frontiers in Ecology and Evolution, investigates the impacts of potential climate change scenarios on the network of Important Bird and Biodiversity Areas (IBAs) across the Caribbean, and Central and South America.

German University Hospital Uniklinik RWTH Aachen and diagnostics company SphingoTec GmbH today announced that the endothelial function biomarker bio-ADM aids in the early risk stratification and management of patients suffering from severe COVID-19, in need for escalated intensive care treatment.

The study provides insights into how the cancers resist treatments, and which patients may benefit from treatment.

researchers from the Center for BrainHealth® at The University of Texas at Dallas are investigating a potential new early indicator of the decline toward Alzheimer's disease: measuring the energy metabolism of the living human brain using cutting-edge imaging techniques.

Steven Poelzing, associate professor at the Fralin Biomedical Research Institute at VTC, led a team of cardiovascular scientists studying electrical conduction in the heart, showing increased sodium and calcium levels in the bloodstream helps keep dangerous heart rhythms at bay.

Researchers at C-Crete Technologies and Rice University have found the right ingredients for cement that does double duty as a structural material and a photocatalytic water purifier with a built-in means of replenishment: simply sand down the material's surface to refresh the photocatalytic quality.

Pioneering neural recordings in patients with Parkinson's disease by UC San Francisco scientists lays the groundwork for personalized brain stimulation to treat Parkinson's and other neurological disorders.

University of South Australia researchers have identified an enzyme that may help to curb chronic kidney disease, which affects approximately 700 million people worldwide.

Daegu Gyeongbuk Institute of Science and Technology (DGIST) scientists in Korea have developed algorithms that more efficiently measure how difficult it would be for an attacker to guess secret keys for cryptographic systems. The approach they used was described in the journal IEEE Transactions on Information Forensics and Security and could reduce the computational complexity needed to validate encryption security.

Modeling coupled with fieldwork explains the mechanism by which strike-slip faults can generate large tsunamis.
