PULLMAN, Wash. - Exposure to the widely used weed-killer glyphosate makes genetic changes to rats that can be linked to increased disease in their grandchildren and great-grandchildren, a new study has found.
Black neighborhoods had a significantly lower rate of bystander automated external defibrillator (AED) use relative to non-Hispanic/Latino white communities, according to researchers at The University of Texas Health Science Center at Houston (UTHealth).
Hispanic/Latino neighborhoods also had lower rates of AED use, according to the study, which was published in a recent edition of Circulation, a journal of the American Heart Association (AHA).
HOUSTON - (Dec. 9, 2020) - Although people of all faiths report growing religious discrimination during the past few years, the phenomenon is most common among Jews and Muslims, according to a new study from researchers at Rice University and West Virginia University (WVU). In addition, Jews and Muslims are much more likely to become victims of violence because of their religious beliefs.
Without drinkable water there is no life. Yet, nearly 1.1 billion people worldwide lack access to fresh water and another 2.4 billion suffer from diseases borne by unclean drinking water. This is because while science has yielded advanced water treatment methods such as membrane distillation and reverse osmosis, these are often difficult to implement in developing countries owing to their high cost and low productivity.
In the wake of the 2017 North Bay fires, the golden hills of Santa Rosa, California, were unrecognizable. Smoky, seared and buried under ash, the landscape appeared desolate, save for some ghostly, blackened - but still alive - oak trees. For Stanford University graduate student, Gabriel Smith, whose family lives in Santa Rosa, the devastation was heartbreaking, but it also offered a unique scientific opportunity: a natural experiment on the effects of wildfires on the microbes that live in soil, which Smith studies in the form of fungi.
Today, a large number of people worldwide suffer from shortage of fresh drinking water, especially in remote rural regions, causing a significant threat to human life and society. While techniques such as membrane distillation and reverse osmosis have been used to treat saline water and alleviate the situation, they suffer from limitations like low productivity, high cost, and high energy consumption.
For decades, one material has so dominated the production of computer chips and transistors that the tech capital of the world -- Silicon Valley -- bears its name. But silicon's reign may not last forever.
MIT researchers have found that an alloy called InGaAs (indium gallium arsenide) could hold the potential for smaller and more energy efficient transistors. Previously, researchers thought that the performance of InGaAs transistors deteriorated at small scales. But the new study shows this apparent deterioration is not an intrinsic property of the material itself.
Philadelphia, December 10, 2020 - A new study in the Journal of the Academy of Nutrition and Dietetics, published by Elsevier, found that changes in the food environment around low-income and high-ethnic/racial minority populations over time impact childhood obesity.
A new study has found one of the challenges in designing systems that involve people interacting with technology is to tackle the human trait of overconfidence.
The study, published in the journal IEEE Control Systems, takes a novel multidisciplined approach in studying "cyberphysical human systems". The research considers the relationship between people and computer systems both from the perspective of control system engineering and behavioural economics.
Osaka, Japan - Researchers at Osaka University demonstrated a new technique for modifying the hydrogen concentration of resistors by applying an electrical voltage. The generated electric field drove the diffusion of hydrogen ions deeper into the perovskite rare-earth nickelate lattice, which led to a tunable "colossal" increase in electrical resistance. This research can lead to new gas sensors and electrically switchable smart materials.
Researchers from the National University of Singapore (NUS) have developed a new way to treat sewage that is much simpler, cheaper and greener than existing methods.
Led by Associate Professor He Jianzhong from the Department of Civil and Environmental Engineering at the Faculty of Engineering, the NUS team found a new strain of bacterium called Thauera sp. strain SND5 that can remove both nitrogen and phosphorus from sewage.
MELVILLE, N.Y., December 9, 2020 -- Several acoustic studies have shown that the position of your eyes determines where your visual spatial attention is directed, which automatically influences your auditory spatial attention. Researchers are currently exploring its impact on speech intelligibility.
Most insects can fly.
Yet scores of species have lost that extraordinary ability, particularly on islands.
On the small islands that lie halfway between Antarctica and continents like Australia, almost all the insects have done so.
Flies walk, moths crawl.
"Of course, Charles Darwin knew about this wing loss habit of island insects," says PhD candidate Rachel Leihy, from the Monash University School of Biological Sciences.
Researchers have found a way to protect highly fragile quantum systems from noise, which could aid in the design and development of new quantum devices, such as ultra-powerful quantum computers.
A new study published in Arthritis & Rheumatology suggests that recent advances in the treatment of rheumatoid arthritis have prolonged patients' lives but also increased healthcare costs.
For the study, investigators examined medical claims data from the National Health Insurance of Taiwan, identifying 29,352 new cases of rheumatoid arthritis from 2003-2016.
