Medical Xpress / Anticipating aging-related mental decline using saliva samples and AI
As humans age beyond early adulthood, their physical and mental functions tend to slowly worsen over time. One of the most common sources of severe mental decline in older adults are neurodegenerative diseases, conditions ...
Phys.org / Blood tests in young bald eagles track PFAS pollution across Wisconsin River sites
It hadn't been a successful morning for the Great Lakes Eagle Health team. Traveling by boat, truck, and foot, the team was searching for active eagle nests along the Wisconsin River in Nekoosa, Wisconsin. Tree one was a ...
Phys.org / Almost half of the world's aquatic environments are severely contaminated by waste, research reveals
"Dirty" or "extremely dirty": these are the classifications of 46% of the world's aquatic environments. This conclusion comes from a study that compiled and systematized data from 6,049 records of waste contamination in aquatic ...
Medical Xpress / GLP-1 drugs tied to lower-calorie, lower-sugar food purchases
Researchers at Steno Diabetes Center Copenhagen reported that starting a GLP-1 receptor agonist (GLP-1RA) coincided with slightly healthier supermarket purchases. Grocery purchases from GLP-1RA users in Denmark contained ...
Medical Xpress / Study of nearly 60,000 women finds no association between COVID vaccine and decrease in childbirth
COVID-19 vaccination is not the cause behind a decrease in childbirth, according to a study from Linköping University, Sweden. The results, published in the journal Communications Medicine, speak to rumors about vaccination ...
Medical Xpress / Mutation in one Parkinson's protein eases cellular traffic jams caused by another
A hallmark of Parkinson's disease is the buildup of Lewy bodies—misfolded clumps of the protein known as alpha-synuclein. Long before Lewy bodies form, alpha-synuclein can interfere with neurons' ability to transport proteins ...
Medical Xpress / Protective mechanism discovered in female brain: Switched-off X chromosome can reactivate to reduce disease severity
Researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have identified a mechanism that protects the female brain from genetic diseases. Although one of the two X chromosomes is switched off in female cells ...
Phys.org / Teaching machines to design molecular switches
In biology, many RNA molecules act as sophisticated microscopic machines. Among them, riboswitches function as tiny biological sensors, changing their 3D shape upon binding to a specific metabolite. This shape-change acts ...
Phys.org / YouTubers love wildlife, but commenters aren't calling for conservation action
YouTube is a great place to find all sorts of wildlife content. It is not, however, a good place to find viewers encouraging each other to preserve that wildlife, according to new research led by the University of Michigan. ...
Phys.org / Graphene sealing enables first atomic images of monolayer transition metal diiodides
Two-dimensional (2D) materials promise revolutionary advances in electronics and photonics, but many of the most interesting candidates degrade within seconds of air exposure, making them nearly impossible to study or integrate ...
Phys.org / Sudanese Copts acquired malaria resistance thanks to a rapid evolutionary process, research reveals
An international study investigating the genomic diversity of the Sudanese population reveals that the Copts originating in Egypt—who settled in the country between the seventh and eleventh centuries—have acquired a genetic ...
Medical Xpress / Immune 'hijacking' by tumors can predict cancer evolution
Predicting tumor progression is one of the major challenges in oncology. Scientists at the University of Geneva (UNIGE) and the Ludwig Institute for Cancer Research have discovered that neutrophils, a type of immune cell, ...
