New study shows providing non-caloric beverages to teens can help them avoid excessive weight gain

A new study published in the New England Journal of Medicine found that adolescents who eliminated sugar-sweetened beverages for one year gained less weight than those who didn't. The study showed that providing non-caloric beverages to teens can be an effective intervention to help combat adolescent obesity.

Growing corn to treat rare disease

Researchers at Simon Fraser University have developed a novel technology to produce an enzyme used to treat lysosomal storage disease, reducing costs by up to $300,000 per year. The breakthrough uses greenhouse-grown maize seeds to manipulate messenger RNAs and control sugar processing, paving the way for more affordable treatments.

Simple ovarian cancer symptom survey that checks for 6 warning signs may improve early detection

A simple three-question paper-and-pencil survey can effectively identify women experiencing symptoms that may indicate ovarian cancer. The study involved 1,200 women and found that the screening tool identified 5% of women with a positive symptom score, resulting in one diagnosis of ovarian cancer.

Columbia researchers report novel approach for single molecule electronic DNA sequencing

Researchers at Columbia University have developed a novel approach for single molecule electronic DNA sequencing that can accurately distinguish four DNA bases using nanopores. The technique, called Nano-SBS, uses distinct chemical tags to label DNA building blocks, overcoming the challenge of small differences among the four nucleotides.

Commercial weight loss program evaluated

A Swedish commercial weight loss program called Itrim was evaluated for its effectiveness, and researchers found that participants lost an average of 11 kg after one year. The program, which includes three different diets and group sessions, showed promising results with the most rigorous diet resulting in the greatest weight loss.
