In the arms race between prey and predator, sophisticated counter strategies evolve, such as signals that reduce the risks to predator and prey by deterring activities before lethal action is necessary.
The adaptor proteins STING and MAVS are components of critical pathogen-sensing pathways that induce innate immunity. Phosphorylation of either adaptor results in activation of the type I interferon pathway and excessive activation of the system is sometimes associated with fatal inflammatory diseases.
Between 300 and 400 cities in the U.S. employ traffic camera programs, according to Montana State University assistant professor Justin Gallagher. Even so, there has long been debate over whether the programs are effective at maximizing public safety and reducing traffic accidents.

American alligators are about as close to dinosaurs as you can get in modern times, and can grow up to 14 feet in length. While much smaller reptiles such as lizards are able to regenerate their tails, the question of whether the much larger alligator is able to regrow their massive tails has not been well studied. A team of researchers from Arizona State University and the Louisiana Department of
As the global coronavirus pandemic continues, scientists are not only trying to find vaccines and drugs to combat it, but also to continuously learn more about the virus itself. "By now we can expect the coronavirus to become seasonal," explains Ralf Bartenschlager, professor in the Department of Infectious Diseases, Molecular Virology, at Heidelberg University. "Thus, there is an urgent need to d

Today, optofluidics is one of the most representative applications of photonics for biological/chemical analysis. The ability of plasmonic structures (e.g., colloidal gold and silver nanoparticles, NPs) under illumination to release heat and induce fluid convection at the micro-scale has attracted much interest over the past two decades. Their size- and shape-dependent as well as wavelength-tunabl
Strain engineering usually refers to a kind of material processing technology which aims to regulate the properties of materials or optimize related devices' performance by inherent or external strain. In recent years, with the development of 2-D materials, the research surrounding strain engineering of 2-D materials (transition metal dichalcogenides [TMDCs], graphene, etc.) has attracted signific
To make the most of their largest and sharpest teeth, prehistoric sharks that lived 300 to 400 million years ago dropped their lower jaws down and rotated them outwards when opening their mouths to catch prey, new research shows. Many modern sharks have row upon row of formidable sharp teeth that constantly regrow and can easily be seen if their mouths are just slightly opened. But this was not a
While respiratory issues continue to be the most common symptom of a COVID-19 infection, new research indicates the disease could also be associated with an increased tendency of the blood to clot, leading to a higher risk of death from COVID-19.
Machine learning has delivered amazing results, but there also have been failures, ranging from the harmless to potentially deadly. New work from University of Houston philosopher Cameron Buckner suggests that common assumptions about the cause behind these supposed malfunctions may be mistaken, information that is crucial for evaluating the reliability of these networks.
