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.

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.
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), was reported today.
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.
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 local conditions but differ in their vulnerability to the environmental changes expected to occur in the future due to global climate change and...
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 system retains after an infection or vaccination that helps protect against reinfection -- gets generated and maintained, as well as the role...
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.
College students reporting a higher level of loneliness also reported a higher level of sedentary behavior and low activity.
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 pollinating insects. They found that areas of mixed crops compared with areas of single crops are visited equally often by foraging bees.
A new study finds that rest, contrary to popular belief, may not always be the best cure after a concussion.
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 'live' virus.
Biomedical engineers say interstitial fluid, the watery fluid found between and around cells, tissues or organs in the body, could provide an excellent medium for early disease diagnosis or long-term health monitoring.
Researchers have experimentally detected the structural change of hydration water confined in the tiny nano-scale pores of layered materials such as clays. Their findings potentially open the door to new options for ion separation and energy storage.
Results from global data show vaccination and a prior COVID-19 infection offer the best defense against severe illness and reinfection.
Intact forests are important climate regulators and harbors of biodiversity, but they are rapidly disappearing. Agriculture is commonly considered to be the major culprit behind forest loss, but the authors of a new article show that agriculture isn't solely to blame. For forest loss associated with the 2014 world economy, over 60% was related to final consumption of non-agricultural products,...
In order to meet climate protection goals, renewable energies are booming -- often wind power. More than 30,000 turbines have already been installed on the German mainland so far, and the industry is currently scrambling to locate increasingly rare suitable sites. Thus, forests are coming into focus as potential sites. A scientific team has now demonstrated that wind turbines in forests impair...
Physicists have experimentally proven that an important theorem of statistical physics applies to so-called 'Bose-Einstein condensates.' Their results now make it possible to measure certain properties of the quantum 'superparticles' and deduce system characteristics that would otherwise be difficult to observe.
Neuroscientists find two distinct cell populations in the striatum are affected differently by Huntington's disease. They believe neurodegeneration of one of these populations leads to motor impairments, while damage to the other population, located in a structure called the striosome, may account for the mood disorders that are often see in the early stages of the disease.
The natural abilities of squid tissues and the creativity of chemists combine to take hydrogel research in new directions.
Recreating natural molecules in the laboratory as part of the search for potential new drugs for disease can be difficult, costly and slow. The problem? Many chemical processes tend to produce not only a version of the molecule found in nature but also a mirror-image version of the molecule that is potentially useless -- or even dangerous. In synthesizing a new, potentially therapeutic molecule...
Steel is one of the most important materials in the world, integral to the cars we drive, the buildings we inhabit, and the infrastructure that allows us to travel from place to place. Steel is also responsible for 7% of global greenhouse gas emissions. In 2021, 45 countries made a commitment to pursue near-zero-emission steel in the next decade. But how possible is it to produce the steel we need...
Traumatic injury to the brain, spinal cord and optic nerve in the central nervous system (CNS) are the leading cause of disability and the second leading cause of death worldwide. CNS injuries often result in a catastrophic loss of sensory, motor and visual functions, which is the most challenging problem faced by clinicians and research scientists. Neuroscientists have recently identified and...
Researchers have successfully demonstrated precision gene editing in miscanthus, a promising perennial crop for sustainable bioenergy production. Biologists edited the genomes of three miscanthus species using CRISPR/Cas9 -- a far more targeted and efficient way to develop new varieties than prior methods. The results will accelerate efforts to tap the huge potential of this highly productive but...
A team of researchers unveils a novel, key aspect of enhancer-mediated regulation of gene expression and proposes a mechanism that explains the tight connection between gene enhancers and promoters.
On the short-lived island of Hunga Tonga Hunga Ha'apai, researchers discovered a unique microbial community that metabolizes sulfur and atmospheric gases, similar to organisms found in deep sea vents or hot springs.
