Washington, DC-- When a meteorite hurtles through the atmosphere and crashes to Earth, how does its violent impact alter the minerals found at the landing site? What can the short-lived chemical phases created by these extreme impacts teach scientists about the minerals existing at the high-temperature and pressure conditions found deep inside the planet?
Current poultry food safety guidelines for Salmonella, the leading cause of foodborne illness outbreaks, are inadequate. A new study conducted by Thomas Oscar, USDA Agricultural Research Service, "Salmonella prevalence alone is not a good indicator of poultry food safety," published in Risk Analysis, explores additional factors that must be considered in order to identify poultry products that are truly safe for human consumption.
Two different interventions both worked to significantly reduce the rate of inappropriate antibiotic prescriptions made by physicians in a telemedicine practice, a new study led by Children's National Hospital researchers shows. This finding, published Aug. 26 in the Journal of General Internal Medicine, could offer a new way to stem the growing problem of antibiotic resistance, particularly as telemedicine grows due to the ongoing COVID-19 pandemic.
ITHACA, N.Y. - At the Berry Patch farm in Stephentown, New York, big, ripe blueberries are waiting to be picked.
The farm is experiencing one of its best seasons to date thanks to better management of fall infestations of spotted wing drosophila (SWD), part of a research collaboration with Greg Loeb, professor of entomology at Cornell AgriTech, part of Cornell University's College of Agriculture and Life Sciences.
During the afternoon of Aug. 26, as major Hurricane Laura nears landfall near the Texas/Louisiana border, NASA satellites have been providing forecasters with a great deal of data on the storm, examining temperature, rainfall capability, storm structure and extent.
Infrared Data Reveals Powerful Rainmaking Capabilities
Turing machines were first proposed by British mathematician Alan Turing in 1936, and are a theoretical mathematical model of what it means for a system to "be a computer."
At a high level, these machines are similar to real-world modern computers because they have storage for digital data and programs (somewhat like a hard drive), a little central processing unit (CPU) to perform computations, and can read programs from their storage, run them, and produce outputs. Amazingly, Turing proposed his model before real-world electronic computers existed.
DALLAS, August 26, 2020 -- Hispanic/Latinx adults who are exposed to smoke from burning wood, vehicle exhaust, pesticides or metals at workplaces are more likely to have abnormalities of the heart structure and function that could lead to cardiovascular disease, according to new research published today in the Journal of the American Heart Association, an open access journal of the American Heart Association.
Rutgers researchers have created a miniature device for measuring trace levels of toxic lead in sediments at the bottom of harbors, rivers and other waterways within minutes - far faster than currently available laboratory-based tests, which take days.
Learning to cross a busy street is anything but easy for a child, especially in places where the traffic doesn't stop.
Children must first identify a safe gap in traffic, use refined motor skills to precisely step off a curb the moment a car passes, and safely reach the other side of the street before the next vehicle arrives.
The good news: Research says parents can help their children--a lot.
Roots play a vital role in crop plants. They take up water and nutrients for the plant and keep it help firmly in the ground. But not all roots are the same.
Different plants have different kinds of roots that help them survive in their environment. Two well-known examples are carrots and cactus. Carrots have a long taproot that penetrates deep into the soil. Cacti usually have shallow roots. These allow them to quickly soak up the little rainfall they receive in the desert.
Researchers in WMG and the Department of Physics at the University of Warwick have found that asymmetric stresses within electrodes used in certain wearable electronic devices provides an important clue as to how to improve the durability and lifespan of these batteries.
They found out that during tumour development the way cells move can change from coordinated and collective to individual and chaotic behaviour. They have just published their research findings in the journal Nature Cell Biology.
Discussions of the growing plastic waste problem often focus on reducing the volume of single-use plastic packaging items such as bags, bottles, tubs and films.
But a new University of Michigan study shows that two-thirds of the plastic put into use in the United States in 2017 was used for other purposes, including electronics, furniture and home furnishings, building construction, automobiles and various consumer products.
The origin of life on Earth is a topic that has piqued human curiosity since probably before recorded history began. But how did the organic matter that constitutes lifeforms even arrive at our planet? Though this is still a subject of debate among scholars and practitioners in related fields, one approach to answering this question involves finding and studying complex organic molecules (COMs) in outer space.
ORLANDO, Aug. 25, 2020 - To help keep first responders safe, University of Central Florida researchers have developed an artificial intelligence method that not only rapidly and remotely detects the powerful drug fentanyl, but also teaches itself to detect any previously unknown derivatives made in clandestine batches.
The method, published recently in the journal Scientific Reports, uses infrared light spectroscopy and can be used in a portable, tabletop device.
