Scientists at McMaster University have identified new biomarkers for Irritable Bowel Syndrome (IBS) in urine, which could lead to better treatments and reduce the need for costly and invasive colonoscopy procedures currently used for diagnosis.

Little is known about the causes of IBS, a chronic and often debilitating gastrointestinal disorder which affects hundreds of thousands of Canadians in which diagnosis is complicated, patients experience a vast spectrum of symptoms and treatment options are limited.

“Diagnostic testing for IBS involves a long process of excluding other related gut disorders, such as inflammatory bowel disease,” explains Philip Britz-McKibbin, lead author of the study and a professor in McMaster’s Depa...

A study from the University of Exeter has found that mycoprotein, the protein-rich food source that is unique to Quorn products, stimulates post-exercise muscle building to a greater extent than milk protein.

The study evaluated the digestion of protein, which allows amino acids (the building blocks of protein) to increase in the bloodstream and then become available for muscle protein building in 20 healthy, trained young men at rest and following a bout of strenuous resistance exercise.

The young men performed the exercise and were then given either milk protein or mycoprotein. Their muscle building rates were then measured using stable isotope labelled “tracers” in the hours following protein consumption.

Animal proteins like milk are an exce...

In a step toward molecular storage systems that could hold vast amounts of data in tiny spaces, researchers have shown it’s possible to store image files in solutions of common biological small molecules.

DNA molecules are well known as carriers of huge amounts of biological information, and there is growing interest in using DNA in engineered data storage devices that can hold vastly more data than our current hard drives. But new research shows that DNA isn’t the only game in town when it comes to molecular data storage.

A study led by Brown University researchers shows that it’s possible to s...
