That’s what DESI was designed to do: take precise measurements of the apparent size of these bubbles (both near and far) by determining the distances to galaxies and quasars over 11 billion years. That data can then be sliced into chunks to determine how fast the universe was expanding at each…

Probiotics Lower Fever Duration in Children with Respiratory Infections
Upper respiratory tract infections (URTIs) are among the most common illnesses affecting children, often leading to fever, discomfort, and missed school days. While probiotics have been studied for their role in preventing infections, their potential as a…

A massive insect study may have made a huge mistake
When French scientists Laurence Gaume and Marion Desquilbet first heard the news about a new international insect decline database, they felt something was off. It suggested that some insect species were actually on the rise – a claim that contradicted years of research.
So, they called each…

AI-powered mammograms: A new window into heart health
Mammograms, with the help of artificial intelligence (AI) models, may reveal much more than cancer, according to a study being presented at the American College of Cardiology’s Annual Scientific Session (ACC.25). The findings highlight how these important cancer screening tools can also be used…

New CRISPR tool enables more seamless gene editing — and improved disease modeling
Advances in the gene-editing technology known as CRISPR-Cas9 over the past 15 years have yielded important new insights into the roles that specific genes play in many diseases. But to date this technology — which allows scientists to use a “guide” RNA to modify DNA sequences and evaluate the…

The fine control of cell mechanics
Our skin and mucous membranes are protected by epithelial cells. This “barrier” tissue performs its function thanks to specialized structures called “junctions.” They ensure cell cohesion and regulate exchanges across the space between cells. Researchers at the University of Geneva (UNIGE), in…

Part of the genetic risk for schizophrenia acts through the placenta
The study, which involved 28 researchers from 18 institutions across Europe and the United States, highlights the placenta as a key element in neuropsychiatric development. The research has demonstrated that specific epigenetic modifications in the placenta, particularly DNA methylation, can…

How a Y chromosome gene may shape the course of heart valve disease
A study led by bioengineers at the University of California San Diego sheds new light on how a type of heart valve disease, called aortic valve stenosis, progresses differently in males and females. The research reveals that this sex-based difference can be traced to a gene on the Y chromosome.

Starting points for the control of protein synthesis
The research field of “cellular IRESes” lay dormant for decades, as there was no uniform standard of reliable methods for the clear characterization of these starting points for the ribosome-mediated control of gene expression. Researchers at the University Hospital Bonn (UKB) and the University…
