The recommendations are clear: physical activity is good for mental health. But it also depends on how varied it is. That's what a new study by researchers at the University of Basel shows, pointing to one of the reasons why well-being suffers during the pandemic.
Scientists from the Institut Pasteur joined forces with Orléans Regional Hospital, Tours University Hospital, Créteil Intercommunal Hospital, Strasbourg University Hospital and Georges Pompidou European Hospital to study the sensitivity of these two variants to neutralizing antibodies present in the serum samples of people who have been vaccinated or previously infected with SARS-CoV-2. They compa
Women account for half of all doctors and medical trainees in Canada, but too often in medicine, that's where gender equality ends. Studies show female physicians earn less, advance slower and face higher risks of burnout than their male peers. So, what can the profession do about it?
A dietary supplement called docosahexanoic acid may guard against the effects of maternal stress on unborn males during early development, a new study shows. Neurodevelopmental disorders like autism and schizophrenia disproportionately affect males and are directly linked to early life adversity caused by maternal stress and other factors, which nutrition might affect. The underlying reasons for
A group of researchers from Russia, Germany, the Czech Republic, and Switzerland contest the common belief that resource-based economies have higher levels of within-country inequality than resource-scarce economies. The researchers document a direct causal link between natural resources and within-country inequality and conclude that the extraction of oil and gas can reduce inequality or has no s
