When surgeons remove patients' kidney stones, they typically leave behind small stones that appear not to be causing problems. However, a new randomized controlled study has shown that leaving these asymptomatic stones behind significantly increases the risk of a patient's relapse in the following five years.
Engineers have developed a method to increase wind farms' energy output. Whereas individual turbines are typically controlled separately, the new approach models the wind flow of the entire collection of turbines and optimizes the control of individual units.
Researchers have genetically sequenced carotid plaque tissue collected from patients within days after a stroke. When compared to stable plaque, researchers discovered the tissues from recent stroke victims contained messenger RNA that can cause inflammation and processes that degrade a key portion of the plaque that protects against rupture.
Researchers have developed a new cardiac cell-derived platform that closely mimics the human heart, unlocking potential for more thorough preclinical drug development and testing, and better modeling for cardiac diseases.
Large dinosaur predators, such as Tyrannosaurus rex, evolved different shapes of eye sockets to better deal with high bite forces, new research has shown.
The star Betelgeuse appears as a brilliant, ruby-red, twinkling spot of light in the upper right shoulder of the winter constellation Orion the Hunter. But when viewed close up, astronomers know it as a seething monster with a 400-day-long heartbeat of regular pulsations. This aging star is classified as a supergiant because it has swelled up to an astonishing diameter of approximately 1 billion...
By flying with hawkmoths during migration, scientists reveal the insects employ sophisticated flight strategies similar to vertebrates
The evolution of the human larynx contributed to the stable voices we use to communicate. The morphological changes do not include the addition of structures but rather the loss of specific vocal folds or cords in the larynx, providing a stable voice quality and controllable voice pitch used when singing or speaking.
Harvested wood products in residential structures will continue to increase carbon storage for the next 50 years, according to a new study.
Researchers have discovered that the electrical stimulation of the eye surface can alleviate depression-like symptoms and improve cognitive function in animal models.
Researchers have demonstrated that ZCB11, a broadly neutralizing antibody derived from a local mRNA-vaccinee against the spreading Omicron variants of SARS-CoV-2, displays potent antiviral activities against all variants of concern (VOCs), including the dominantly spreading Omicron BA.1, BA1.1 and BA.2. Critically, either prophylactic or therapeutic ZCB11 administration protects lung infection...
A research team has developed a sensing technology that can detect whether a substance was exposed to light using metahologram.
For birds that inhabit developed areas of the Pacific Northwest, the reduction in noise and commotion from COVID-19 lockdowns may have allowed them to use a wider range of habitats in cities, a new study finds.
A fundamental discovery about a driver of healthy development in embryos could rewrite our understanding of what can be inherited from our parents and how their life experiences may shape us.
Some bat species are more likely to be found in cities than in the countryside. A scientific team has now investigated which characteristics are typical for urban and rural bats. The team found that bat species with higher affinity to cities are characterized by relatively low frequencies and long durations of their echolocation calls, a small body size and flexibility in the choice of their...
A professor of chemical and biomolecular engineering has summarized methods of making zeolites in the lab and examined how the emergence of data analytics and machine learning are aiding zeolite design.
Researchers say that an experimental dendrimer nanoparticle treatment called OP-101 substantially reduced the risk of death and need for a ventilator in a study of 24 severely ill adults hospitalized with COVID-19.
The discovery of how to shift damaged brain cells from a diseased state into a healthy one presents a potential new path to treating Alzheimer's and other forms of dementia, according to a new study.
Whether networks with a high level of cooperation emerge in a community depends on how quickly individuals leave -- for example, because they are exploited by others. Researchers investigated this problem by modeling a well-known cooperation game. They consider a spatial network, where players can relocate between different patches if they judge the local conditions to be unfavorable.
Materials scientists have recently discovered a new mechanism to increase the strength and ductility of a high-entropy alloy, two properties which normally vary inversely with each other. The findings provide important insights for the future design of strong yet ductile high-entropy alloys and high-entropy ceramics.
A new analysis by education researchers reveals best practices and challenges for online K-12 education.
Findings from a new study offer a new potential method for cleaning wastewater after use by textiles, cosmetics or other industries.
Researchers had a solution, but they also had a problem. They had created a novel and highly promising material to improve the success of vascular grafts, but they needed a better way to test how well it worked.
Compelling new research challenges the deeply ingrained idea that diet alone should be adequate for everyone seeking to shed pounds. A new rigorous study has the potential to help reshape the science of weight-loss programs so they can be personalized for individual patients with difficult-to-treat obesity.
