New way to wrap liquid drops could improve drug delivery

Researchers have developed a faster, cheaper way to coat liquid medication, an invention that could improve how drugs are delivered in the body.

The new encapsulation technology, developed by engineers at the University of Waterloo, uses gravity and other natural forces to wrap drops as they fall through a thin layer of liquid shell floating on a base liquid.

Once hardened, or cured, by exposure to ultraviolet light, the shell houses and protects the liquid core inside.

Rising emissions are turning arctic permafrost into a carbon source, research shows

Arctic regions have captured and stored carbon for tens of thousands of years, but a new study shows winter carbon emissions from the Arctic may now be putting more carbon into the atmosphere than is taken up by plants each year.

Mathematical modelling vital to tackling disease outbreaks

Predicting and controlling disease outbreaks would be easier and more reliable with the wider application of mathematical modelling, according to a new study. 

The study was conducted by researchers at the University of Waterloo, University of Maryland and Yale’s School of Public Health.

AI system more accurately identifies collapsed lungs using chest x-rays

New assistive technology can diagnose collapsed lungs from chest x-rays with a higher degree of accuracy than radiologists.

The system, developed at the University of Waterloo, uses artificial intelligence (AI) software to search a huge database of x-ray images with known diagnoses for comparison to x-rays of new patients with unknown conditions.

That approach enables researchers to identify 75 per cent of cases of collapsed lungs, or pneumothorax. On average, medical specialists diagnose fewer than 50 per cent of cases when chest x-rays are used.
