When the COVID-19 pandemic emerged in 2020, the R rate became well-known shorthand for the reproduction of the disease. Yet a new study suggests it’s time for ‘A Farewell to R’ in favour of a different approach based on the growth rate of infection rat…

Researchers solved one of the biggest problems with existing wearable pressure sensors: even the slightest amount of pressure, something as light as a tight long sleeve shirt over a sensor, can throw them off track — and they did it by innovating a fi…

A major tool against malaria in Africa has been the use of rapid diagnostic tests, which have been part of the ‘test-treat-track’ strategy in Ethiopia, the second most-populated country in Africa. But researchers studying blood samples from more than 1…

Researchers have discovered that people tend to give more praise to someone for their good deeds as an adult after discovering that person has also had to overcome adversity or suffering earlier in life, such as abuse and neglect as a child.

Most people in the U.S. consume too much salt; adult Americans typically eat twice the daily amount recommended by dietary guidelines. Bread may not seem like an obvious culprit; however, due to high consumption and relatively high salt content, baked …

Using bioinformatics tools and programming, researchers identified five specific mutations that are far more prevalent in Delta Plus infections compared to Delta infections, including one mutation, K417N, that is present in all Delta Plus infections bu…

Engineers developed a technique that allows them to measure the generation rate and half-life of circulating tumor cells (CTCs) in mice.

A new study has identified warning signs of ecosystem collapse at a wetland of international significance in Papua New Guinea.

Researchers used liquid gallium to create an antiviral and antimicrobial coating and tested it on a range of fabrics, including face masks. The coating adhered more strongly to fabric than some conventional metal coatings, and eradicated 99% of several…

The ability to form episodic memories declines with age, certain dementias, and brain injury. However, a new study shows that low frequency repetitive transcranial magnetic stimulation delivered over the left prefrontal cortex of the brain can improve …

Asian elephants are keen to cooperate with friends and have evolved strategies to mitigate competition in their social groups, but cooperation breaks down when food resources are limited, according to new research. The study sheds light on the evolutio…

A new study suggests that machine learning using viral genomes may predict the likelihood that any animal-infecting virus will infect humans, given biologically relevant exposure.

A set of 7 symptoms, considered together, can be used to maximize detection of COVID-19 in the community, according to researchers.

Air pollution likely contributed to almost 6 million premature births and almost 3 million underweight babies in 2019, according to a global burden of disease study and meta-analysis that quantifies the effects of indoor and outdoor pollution around th…

‘Efficient coding theory’ describes the most perfect, low-energy way to design a light-detecting device for a future camera or prosthetic retina. Or you could just look at a mammalian retina that’s already organized this way. In a pair of papers on ret…

While research has shown that poor cardiovascular health can damage blood flow to the brain increasing the risk for dementia, a new study indicates that poor mental health may also take its toll on cognition.

A new research study turns cancer scientists into molecular detectives, searching for clues for why certain cancers are able to spread and evolve by studying tissues collected within hours of death.

A new meta-analysis assessed data from 15 published studies to see how a single session of intense exercise affects young and middle-aged healthy adults in the hours prior to bedtime. And while no two bodies are the same, the researchers did find that …

Scientists develop stronger and tougher glass, inspired by the inner layer of mollusk shells. Instead of shattering upon impact, the new material has the resiliency of plastic and could be used to improve cell phone screens in the future, among other a…

Researchers show that chronic hyperglycemia impairs working memory performance and alters fundamental aspects of working memory networks.
