Phys.org / What's in a name? Study finds two dahlia-damaging viruses are variants of same species
For decades, two different viruses were believed to be responsible for a common, untreatable disease in dahlias, a colorful, high-value flower grown worldwide. Virologists at Washington State University have now learned that ...
Medical Xpress / Working outside the home protected mental health for older adults during the pandemic, finds study
New research using data from the Canadian Longitudinal Study on Aging (CLSA) reveals that employment stability and in-person work buffered older adults against depression during the first year of COVID-19. Older adults who ...
Medical Xpress / Genetic clues in 3,000 Indians reveal new lipid routes to cardiometabolic disease
A study conducted in an Indian population has identified new molecular pathways that contribute to cardiovascular disease, which had not been reported previously in studies of Europeans. Dharambir Sanghera of the University ...
Medical Xpress / How scientists have changed their view of insomnia
Insomnia may have been torturing humanity since ancient times, but over the last 20 years scientists have made progress in their understanding of chronic sleep deprivation.
Medical Xpress / Calcium surges in brain immune cells may switch anxiety on and off
Researchers had previously discovered a population of immune cells within the brain that can act as accelerators and brakes for anxiety in mice. Now, new research from the lab of Mario Capecchi, Ph.D., professor of human ...
Phys.org / New genetic evidence from Stajnia Cave reveals the oldest Neanderthal group reconstructed in Central-Eastern Europe
An international study published in Current Biology presents the results of the analysis of ancient mitochondrial DNA obtained from eight Neanderthal teeth discovered in Stajnia Cave, Poland. For the first time, the research ...

Tech Xplore / This simple solar cell manufacturing tweak could solve perovskites' biggest weakness
A technique that improves the performance and stability of next-generation solar cells—without adding any chemicals or coatings—has been demonstrated by researchers from Korea University and the University of Surrey.
Phys.org / Hollow-sphere catalyst enables greener production of 99% pure propene at room temperature
The world's appetite for propene (propylene) is growing faster than the chemical industry can keep up. This petrochemical product powers the production of acrylonitrile, propylene oxide, high-velocity fuels, and, most importantly, ...
Tech Xplore / Colored films enable patterns on photovoltaic modules
Scientists at the Fraunhofer Institute for Solar Energy Systems ISE have succeeded in creating colored films with transparent cutouts, thereby producing realistic-looking designs on photovoltaic modules. In this way, roof ...
Phys.org / Geoengineering could protect Amazon rainforest from climate change
Geoengineering could protect the Amazon rainforest from climate change, new research shows. Stratospheric aerosol injection (SAI) aims to artificially cool Earth by increasing the reflection of incoming solar radiation, thereby ...
