New ‘whipping jet’ sprayer controls how aerosols move
Scientists have invented a new ‘whipping jet’ sprayer that allows for greater control over how aerosols move. The device could benefit pharmaceutical, automotive, food processing, carbon capture and other industries.
Unprecedented levels of high-severity fire burn in Sierra Nevada
High-severity wildfire in California’s Sierra Nevada forests has nearly quintupled compared to before Euro-American settlement, rising from less than 10% per year then to up to 43% today, a new study finds.
New, more accurate computational tool for long-read RNA sequencing
Researchers have developed a new computational tool that can more accurately discover and quantify RNA molecules from these error-prone long-read RNA sequencing data. The tool, called ESPRESSO (Error Statistics PRomoted Evaluator of Splice Site Options…
Finding a new way: Orienteering can train the brain, may help fight cognitive decline
The sport of orienteering, which draws on athleticism, navigational skills and memory, could be useful as an intervention or preventive measure to fight cognitive decline related to dementia, according to new research.
Vulnerability of red sea urchins to climate change depends on location
A new study of red sea urchins, a commercially valuable species, investigated how different populations respond to changes in their environments. The results show that red sea urchin populations in Northern and Southern California are adapted to their …
Regulating immunological memory may help immune system fight disease
Scientists have long sought to better understand the human body’s immune responses that occur during various diseases, including cancer and inflammatory diseases. Scientists have now analyzed how immunological memory — the memory the body’s immune sys…
Female and male hearts respond differently to stress hormone in mouse study
Female and male hearts respond differently to ‘fight or flight’ stress hormone, according to a new study in mice. It may help explain sex differences in arrhythmia risk.
Loneliness associated with unhealthful diets and physical inactivity among US college students
College students reporting a higher level of loneliness also reported a higher level of sedentary behavior and low activity.
Mixture of crops provide ecological benefits for agricultural landscapes
There are often too few flowering plants in agricultural landscapes, which is one reason for the decline of pollinating insects. Researchers ave now investigated how a mixture of crops of faba beans (broad beans) and wheat affects the number of pollina…
Rest isn’t best: Getting kids back to school sooner after a concussion can mean a faster recovery
A new study finds that rest, contrary to popular belief, may not always be the best cure after a concussion.
First computational reconstruction of a virus in its biological entirety
A researcher has created a computer reconstruction of a virus, including its complete native genome. Although other researchers have created similar reconstructions, this is believed to be the first to replicate the exact chemical and 3D structure of a…
