In a survey, UC San Diego researchers report most patients are willing to share medical records for research purposes, with a few caveats.
Evidence shows that higher levels of physical activity -- regardless of intensity -- are associated with a lower risk of early death in middle aged and older people.
Freshwater wetlands from Georgia to New York are home to a previously unrecognized species of medicinal leech, according to scientists at the Smithsonian's National Museum of National History. The new species was first identified from specimens collected in southern Maryland less than 50 miles from Washington, D.C., prompting a search through marshes and museum collections that revealed that the leech has long occupied a range that stretches throughout the eastern United States.
A molecule called tRNA is an essential component of the human genome that acts as a translator. When researchers and clinicians investigate the genome's relation to disease, they have traditionally focused on mutations in the code for proteins. But now researchers at Western University have shown that the genes encoding tRNAs can also have mutations that cause the code to be misread, and in greater numbers than previously thought.
Although each and every one of us goes through it, aging is a poorly understood process. Researchers have used a biomarker called the epigenetic clock to identify a gene that is closely linked to aging in humans. This study shows that the epigenetic clock could be a good tool for improving our understanding of the molecular mechanisms behind aging.
Indiana University data scientists have found evidence that women and older adults are more likely to be prescribed multiple drugs that interact dangerously.
Biologists have developed the first system for determining gene expression based on machine learning. Considered a type of genetic Rosetta Stone for biologists, the new method leverages algorithms trained on a set of known plant genes to determine a species-wide set of transcribed genes, or 'expressome,' then creates an atlas of expressible genes. The method carries implications across biology, from drug discovery to plant breeding to evolution.
The use of remote sensing equipment for data collection has revolutionized biological data collection in the field, but researchers still need tools to help analyze the data. RadialPheno supports the study of phenology -- the timing of developmental events like flowering and fruiting -- by providing a visualization system that identifies temporal patterns. Such tools are urgently needed to understand how climate change is affecting ecosystems by altering the timing of phenological events and ecological interactions.
Earlham Institute (EI), with the University of East Anglia (UEA), have developed a new method to rapidly identify the sources of bee pollen to understand which flowers are important for bees.
Rutgers University-Camden neuroscientist Nathan Fried and colleagues from the University of Pennsylvania have developed a method that can more accurately gauge pain in mice, which could lead researchers to discover new ways to treat pain in human patients.
