World’s first full-cell dual-cation battery developed in Ireland

Researchers at University of Limerick (UL) have developed a battery that could reshape the future of electric vehicles and portable electronics. Their breakthrough in energy storage technology has seen the development of the world’s first full-cell dual-cation battery.

This innovative system combines lithium and sodium ions to significantly enhance both battery capacity and stability, marking a new frontier in sustainable energy research.

The work, published in Nano Energy, was led by Hugh Geaney, Associate Professor of Chemistry at UL’s Department of Chemical Sciences and Principal Investigator at UL’s Bernal Institute, and Government of Ireland postdoctoral fellow, Dr. Syed Abdul Ahad, his colleague at the Department and the Bernal Institute.

Scientists find ways to boost memory in aging brains

Memory loss may not simply be a symptom of getting older. New research from Virginia Tech shows that it’s tied to specific molecular changes in the brain and that adjusting those processes can improve memory.

In two complementary studies, Timothy Jarome, associate professor in the College of Agriculture and Life Sciences’ School of Animal Sciences, and his graduate students used gene-editing tools to target those age-related changes to improve memory performance in older subjects. The work was conducted on rats, a standard model for studying how memory changes with age.

“Memory loss affects more than a third of people over 70, and it’s a major risk factor for Alzheimer’s disease,” said Jarome, who also holds an appointment in the School of Neuroscience. “This work shows that memory decline is linked to specific molecular changes that can be targeted and studied. If we can understand what’s driving it at the , we can start to understand what goes wrong in dementia and eventually use that knowledge to guide new approaches to treatment.”

Longstanding Mystery Solved: Scientists Discover How Life’s Most Essential Molecule Enters Mitochondria

Yale researchers revealed how vitamin B5 fuels mitochondria, offering new insight into brain and metabolic disorders. The human body produces a molecule from vitamin B5 that plays a crucial role in nearly every metabolic process needed for life. When the production of this molecule is disrupted.

First-ever detection of ‘heavy water’ in a planet-forming disk

The discovery of ancient water in a planet-forming disk reveals that some of the water found in comets—and maybe even Earth—is older than the disk’s star itself, offering breakthrough insights into the history of water in our solar system.

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have made a first-ever detection of doubly deuterated water (D₂O, or “heavy water”) in a planet-forming disk around V883 Ori, a young star. This means that the water in this disk, and by extension the water in comets that form here, predates the birth of the star itself, having journeyed through space from ancient molecular clouds long before this solar system formed.

The research is published in the journal Nature Astronomy.
