A survey of 5,500 Brazilian and Italian school students aged 14-16 pointed to nationality, social perceptions of science, and household income as more influential than religion. The findings are published in PLOS ONE Religion influences secondary school students' understanding and acceptance of evolutionary theory, but social and cultural factors such as nationality, perceptions of science, and household income are more influential, according to a study involving 5,500 Brazilian and [...]

One potential application: Enhancing the sensitivity of atomic magnetometers used to measure the alpha waves emitted by the human brain. Scientists are increasingly seeking to discover more about quantum entanglement, which occurs when two or more systems are created or interact in such a manner that the quantum states of some cannot be described independently of the quantum states of the others. The systems are correlated, even when they are separated by a large distance. Interest in [...]

According to new research, protein restriction is effective in combating obesity and diabetes. According to a study comparing the effects of protein and calorie restriction diets in humans, reducing protein consumption may help control metabolic syndrome and some of its primary symptoms, such as obesity, diabetes, and high blood pressure (hypertension). The study’s findings were recently published in the journal Nutrients. The term “metabolic syndrome” refers to a [...]

For the first time, scientists at the Federal University of São Paulo (UNIFESP) in Brazil have shown that infection by SARS-CoV-2, the virus that causes COVID-19, changes the functioning of host cell RNA. They arrived at this conclusion by analyzing 13 datasets obtained during four studies of viral, human and animal cell RNA. The most recent study, reported in an article published in Frontiers in Cellular and Infection Microbiology, examined the epitranscriptome of [...]

According to the study, the amino acid taurine could be employed in anti-aging therapies. Our cells produce potentially toxic by-products known as “free radicals” when they break down the oxygen we breathe and the food we consume each day in order to exist. Some of these molecules carry out important biological functions, but if there are too many of them, the internal cell structures can be harmed, impairing the cells’ ability to function and possibly resulting in chronic [...]

In the early stages of the epidemic, the majority of those who were confined to their homes said that they felt that time moved more slowly and that they felt lonely as a result. According to a report in the journal Science Advances, the COVID-19 pandemic has altered how individuals perceive the passing of time. The majority of research participants (65%) reported feeling that time was moving more slowly at the conclusion of the first month of social isolation, which [...]

Brown adipose tissue is activated by the cold to release anti-inflammatory compounds. Over 40% of adult Americans are obese, a complicated condition that raises the risk of diabetes, heart disease, and several types of cancer. By creating low-grade chronic inflammation and the buildup of immune cells in insulin-sensitive tissues, obesity is one factor that can contribute to other health issues. Scientists believe that reversing, or “resolving,” this chronic inflammation [...]

Vaccines can be made over 25% more effective by adding left-handed chiral gold nanoparticles as adjuvants, according to a study by an international collaboration in which Brazilian researchers took part. An article reporting the results is published in Nature. Three research groups collaborated on the study, one affiliated with the University of Michigan in the United States, and another with Jiangnan University in China. The Brazilian group was led by André Farias [...]
