Recent research, including a new study from the Max Planck Institute for Evolutionary Anthropology and the University of Turku, challenges traditional assumptions of universal male dominance in mammals. Analysing three decades of data on wild mountain gorillas, which have long been considered to have strictly male-biased hierarchies, this study reveals that most females can overpower at least one adult male, securing wins in conflicts and priority access to resources. These findings emphasise the complexity of power dynamics between the sexes in great apes and indicate that human patriarchy is probably a cultural construct rather than a primate legacy.
The first paper from a multi-year clinical research study has been published in The Lancet Infectious Diseases: Dynamics of Endemic Virus Re-emergence in Children in the USA Following the COVID-19 Pandemic (2022-2023): A Longitudinal Immunoepidemiologic Surveillance Study and demonstrates how the approach can improve modeling to better predict future outbreaks.
The paper shares findings from a multicenter clinical research study, one of many studies that are part of the recently launched PREMISE (Pandemic Response Repository through Microbial and Immune Surveillance and Epidemiology) program, led by Dr. Daniel Douek at the National Institutes of Health’s (NIH) Vaccine Research Center (VRC). Data collected during the first year of the PREMISE study, 2022-2023, shows for the first time how non-pharmaceutical interventions such as masking and distancing targeted towards SARS-CoV-2 during the pandemic also decreased circulation rates of and population immunity to common respiratory pathogens in children. The study provides new evidence-based insight into what was driving the large post-pandemic rebound in these diseases and enables more accurate predictions for the future.
Over 25 years of studying individuals aged 80 and older — dubbed “SuperAgers” — Northwestern University scientists have seen some notable lifestyle and personality differences between SuperAgers and those aging typically — such as being social and gregarious — but “it’s really what we’ve found in their brains that’s been so earth-shattering for us,” the corresponding author said.
Large language models such as ChatGPT recognise widespread myths about the human brain better than many educators. However, if false assumptions are embedded into a lesson scenario, artificial intelligence (AI) does not reliably correct them. These were the findings of an international study that included psychologists from Martin Luther University Halle-Wittenberg (MLU). The researchers attribute this behaviour to the fundamental nature of AI models: they act as people pleasers. However, this problem can be solved by a simple trick. The study was published in the journal “Trends in Neuroscience and Education”.
Bethesda, MD (Aug. 1, 2025) – Despite social media helping to increase awareness of irritable bowel syndrome (IBS) among the public (81% of health care providers agree) and advancements in treatment over the past decade, IBS symptoms continue to significantly impact patients' daily lives and productivity, according to a new survey released by the American Gastroenterological Association (AGA), in partnership with The Harris Poll, a Stagwell (STGW) agency.
