A new ‘hybrid’ hydrogel, which allows clinicians to safely deliver stem cells to the site of a brain injury in mice, has been developed by researchers from the University of Melbourne and the Australian National University.

A hydrogel is a water-based gel that can be used to deliver substances into the body and can be used to promote the effective growth of new cells.

Published in Nature Communications, the proof-of-concept breakthrough solves a major challenge faced by stem cell researchers since the 1980s – keeping stem cells alive for long enough to allow them to evolve into the c...

Inflammatory diseases like rheumatoid arthritis have complex disease mechanisms that can differ from patient to patient with the same diagnosis. This means that currently available drugs have little effect on many patients. Using so-called digital twins, researchers at Karolinska Institutet have now obtained a deeper understanding of the “off and on” proteins that control these diseases...

New Cleveland Clinic research showed that erythritol, a popular artificial sweetener, is associated with an increased risk of heart attack and stroke. Findings were published today in Nature Medicine.

Researchers studied more than 4,000 people in the U.S. and Europe and found those with higher blood erythritol levels were at elevated risk of experiencing a major adverse cardiac event such as heart attack, stroke or death. They also examined the effects of adding erythritol to either whole blood or isolated platelets. Results revealed that erythritol made platelets easier to activate and form a clot. Pre-clinical studies confirmed ingestion of erythritol heightened clot formation.

“Sweeteners like erythritol, have rapidly increased in popularity in recent years but there needs to...

Researchers may be able to predict cardiovascular disease — such as arterial fibrillation and heart failure — in patients by using artificial intelligence (AI) to examine the genes in their DNA, according to a new ...
