The unusual head of a fish and the puzzle of its genes

University of Konstanz
Peer-Reviewed Publication

Which genetic factors can break the symmetry of an animal's body? To answer this question, a Konstanz research team led by evolutionary biologist Axel Meyer studied a cichlid fish whose head is bent either to the left or right. The results show how closely behavioural preferences and genes are linked.

New evidence static electricity sense could be a factor in evolution of extreme body shapes of treehoppers

University of Bristol
Peer-Reviewed Publication

Could detecting static electricity be a factor in explaining why treehopper insects have evolved such bizarre body shapes?

That is the hypothesis put forward in a new research paper published in PNAS by Dr Sam England, who completed his PhD at Bristol in 2023, and Professor Daniel Robert, Professor of Bionanoscience at the University of Bristol.

How the common fungus Candida albicans colonizes the gut

Baylor College of Medicine
Peer-Reviewed Publication

About 80% of people have the fungus Candida albicans in their gut. Although most of the time it persists unnoticed for years causing no health problems, C. albicans can turn into a dangerous microbe that causes serious diseases in many organs, including the urinary tract, lungs and brain. Working with a mouse model, researchers at Baylor College of Medicine and international collaborators have discovered unexpected factors that help C. albicans settle and persist in the gut. The findings expand our knowledge of the fungus-gut interactions and offer potential solutions to reduce colonization.

Demographic data supporting FDA authorization of AI devices for Alzheimer disease and related dementias

JAMA Network
Peer-Reviewed Publication

About The Study: Transparency of evidence supporting Food and Drug Administration (FDA) authorization of artificial intelligence (AI)- and machine learning -based devices for Alzheimer disease and related dementias was limited, precluding effective evaluation of training and validation dataset representativeness. Disease status (i.e., dementia type and distribution), age, and sex were reported for fewer than half of devices, while race and ethnicity data were rarely disclosed, raising uncertainty about real-world generalizability and clinical accuracy in intended populations.

Both humans, nature change where lions and hyenas move

University of Georgia
Peer-Reviewed Publication

Lions and hyenas may occasionally spend less time near roads crowded by humans, according to new research from the University of Georgia.

Too many male animals in zoos could hamper conservation of endangered species, warn scientists

University of Bath
Peer-Reviewed Publication

Scientists from the Milner Centre for Evolution at the University of Bath have found that factors including mating systems and brood size could predict the ratio of males to females for animals bred in captivity.
