Breakthrough in sensing at the nanoscale

The discovery enables rapid localization and measurement of cells within living environments at the nanoscale, such as changes to a single cell in response to chemical signals. The ultra-sensitive nanoparticles, or SuperDots, can detect individual particles with thousand times more sensitivity than existing materials.

Family history doubles aortic stenosis risk

A study found that patients with a first degree relative registered with aortic stenosis have a 2.04-fold increased risk of developing the condition. This risk is doubled in those with ischaemic heart disease and family history, highlighting the importance of genetic factors and familial clusters in the development of aortic stenosis.

Anticoagulant does not reduce rate of ischemic events among certain patients undergoing PCI

A study published in the Journal of the American Medical Association found that otamixaban, a novel anticoagulant, did not reduce ischemic events but increased bleeding among patients with non–ST-segment elevation acute coronary syndromes undergoing percutaneous coronary intervention (PCI). The trial compared otamixaban with unfraction...

DNA 'cages' may aid drug delivery

Researchers at McGill University have created DNA 'cages' that can encapsulate small-molecule drugs and release them in response to a specific stimulus. The discovery has the potential to revolutionize drug delivery methods, offering precise control over drug release and reducing toxicity.

Move it and lose it: Every 'brisk' minute counts

A University of Utah study found that higher-intensity activity, even in short bouts, can lower the risk of obesity and promote weight loss. The research used data from over 4,500 adults and showed that daily minutes spent in high-intensity activity can offset up to half a pound of weight.
