Wild fruits from Southern Africa show good potential to supplement diets with the building blocks of protein. Researchers from the University of Johannesburg studied 14 species. Two of the fruits contain several essential amino acids. All exceed the RDA for lysine. People can only obtain lysine from their food or supplements. Healthy development in children requires lysine. Maintaining a robust immune function also needs it, especially against viruses.

A team at National Institute of Informatics, Japan and University of Waterloo developed a method that automatically transforms models of controller software into models that satisfy safety requirements even when uncertainty in sensing the state of the environment. In addition, the method generates formulas that represent the degree of uncertainty that the controller software can tolerate. The method can be applied to various controller systems that interact with the external environment, including autonomous vehicles.

This Oncotarget study suggests that miR-21, miR-31 and miR-520e expression might be a treatment dependent marker for EGFRI induced skin rash.

A new study in the Journal of the European Economic Association, published by Oxford University Press, finds that electoral districts with a larger gender pay gaps show favoritism toward male political candidates in Parliamentary elections, with fewer female candidates on the ballot.

Estrogen has been thought to play a role in a woman's risk of developing Alzheimer disease (AD). A new study has taken a different approach to identifying risk factors for AD by examining the association between a woman's reproductive life span as an indicator of endogenous estrogen exposure and levels of cerebrospinal fluid biomarkers. Study results are published online in Menopause, the journal of The North American Menopause Society (NAMS).

A new method developed by a Kyoto University researcher is the first to allow users to analyse snow leopard stress hormones in the field. The findings are published in the British Ecological Society journal, Methods in Ecology and Evolution.

The first iron-catalyzed phosphinoylazidation of alkenes under relatively mild reaction conditions affording compounds containing nitrogen and phosphorus is reported. This method is practically useful to deliver the azidophosphonates and requires relatively low loading of catalyst. Mechanistic studies confirmed the radical nature of the reaction and disclosed the unusually low activation energy 4.8 kcal/mol of radical azido group transfer from the azidyl iron(III) phthalocyanine species (PcFeIIIN3) to a benzylic radical rather than from the high-valent PcFeIV(N3)(Radical) species.

A project led by the universities of Bath, Cardiff and Essex finds people judge pandemic risk by magnitude of policy response

Using artificial intelligence, UT Southwestern scientists have identified thousands of genetic mutations likely to affect the immune system in mice. The work is part of one Nobel laureate's quest to find virtually all such variations in mammals.

A study published in Nature Astronomy concludes that known geochemical processes can't explain the levels of methane measured by the Cassini spacecraft on Saturn's icy moon. While the paper by no means suggests that life exists on Enceladus, the results would be consistent with microbial activity similar to that known to occur at hydrothermal vents in Earth's oceans. 

When traffic is clogged at a downtown intersection, there may be a way to reduce some of the congestion: Eliminate a few left turns.

People who receive mRNA COVID-19 vaccines are up to 91 percent less likely to develop the disease than those who are unvaccinated, according to a new nationwide study of eight sites, including Salt Lake City. For those few vaccinated people who do still get an infection, or "breakthrough" cases, the study suggests that vaccines reduce the severity of COVID-19 symptoms and shorten its duration.

The Society for Academic Emergency Medicine (SAEM) is pleased to announce the release of the first publication in a series of Guidelines for Reasonable and Appropriate Care in the Emergency Department (GRACE), which focuses on low-risk chest pain.

A new national study published in Psychiatric Services finds that over a quarter of US adults with depression or anxiety symptoms reported needing mental health counseling but were not able to access it during the COVID-19 pandemic. Researchers analyzed data from nearly 70,000 adults surveyed in the US Census Household Pulse Survey in December 2020.

Veterinarians at the University of California, Davis, have found that a cat's DNA alters how it responds to a life-saving medication used to treat hypertrophic cardiomyopathy, or HCM, a heart disease that affects 1 in 7 cats.

Researchers at the University of Massachusetts Amherst recently discovered that the ability of agricultural grasses to withstand drought is directly related to the health of the microbial community living on their stems, leaves and seeds.

Five Simon Fraser University scholars are among international scientists sounding an alarm over the "pervasive social and ecological consequences" of the destruction and suppression of the knowledge systems of Indigenous Peoples and local communities.

As businesses and educational institutions are grappling with how to adopt more diversified hiring practices, a study of recruitment data suggests a simple and efficient way of increasing diversity in applicant pools.

How the media frame stories about science affects the public's perception about scientific accuracy and reliability, and one particular type of narrative can help ameliorate the harm to science's reputation sometimes caused by different journalistic approaches to scientific storytelling, according to a new study led by a University at Buffalo researcher.

Switchgrass, a native prairie species, is championed as a promising bioenergy crop due to its ability to grow across many climates. It is also known to associate with beneficial microbes. To better understand the relationship between switchgrass and soil microbes, researchers at Michigan State University and Washington State University examined soil microbial communities and root traits among 12 switchgrass cultivars that had been planted in the same plot over nine years.
