Milk protein enables targeted drug delivery

PHARMACEUTICALS

Chemists at Université Laval have combined a common protein found in cow and sheep milk with mesoporous silica to create a new type of functionalized nanoparticle that can deliver drugs to specific regions of the body based on differences in pH. The technology could even be made capable of distinguishing cancer cells from healthy cells....

Fireflies inspire LED coating

MATERIALS
BY:

The jagged pattern of scales on the abdomen of a firefly has inspired researchers to create a new coating for light emitting diodes (LEDs) that extracts 55 per cent more light than noncoated LEDs. Researchers in Belgium examined fireflies and noted scales with a periodically repeating...

Omega-3 fatty acids affect gene expression

HEALTH

Researchers at Université Laval have used transcriptomics and metabolomics to analyse the health effects of omega-3 polyunsaturated fatty acid (PUFA) dietary supplements. The results provide new insight into how these chemicals work their benefits — and why they don’t affect everyone the same way. ...

Analyzing oligosaccharides to detect adulterated juice

FOOD CHEMISTRY

In the mid-1980s, a Florida citrus growers’ organization offered $50,000 to anyone who could develop an analytical technique for detecting orange juice adulterated with cheap beet juice. Graduate student Nicholas Low, who was working on enzymes responsible for carbohydrate hydrolysis, thought he had a solution.
