An international research team led by RMIT University have created tiny particles, known as nanodots, made from a metallic compound that can kill cancer cells while leaving healthy cells largely unharmed.
While this work is still at the cell-culture stage – it hasn’t been tested in animals or people – it points to a new strategy for designing cancer treatments that exploit cancer’s own weaknesses.
Using catalytic chemistry, researchers at Institute of Science Tokyo have achieved dynamic control of artificial membranes, enabling life-like membrane behavior. By employing an artificial metalloenzyme that performs a ring-closing metathesis reaction, the team induced the disappearance of phase-separated domains as well as membrane division in artificial membranes, imitating the dynamic behavior of natural biological membranes. This transformative research marks a milestone in synthetic cell technologies, paving the way for innovative therapeutic breakthroughs.
Thousands of NHS knee replacement operations are cancelled at short notice every year, many for avoidable reasons, according to a new study published today [1 December]. This costs the NHS millions of pounds and increases waiting times for patients, many of whom are in severe pain.
Changing the amount of sweetness in a person’s diet has no impact on their liking for sweet foods or their health, the results of a new trial suggest.
