This image shows vascularized pancreatic islets (areas in green) bioengineered by researchers and transplanted into a mouse. The bioengineered islets — which have a network of blood vessels (shown in red) and secrete hormones like insulin — are shown seven days after transplant. Scientists reporting research data in Cell Reports say their goal is to one day translate the bioengineering process used to generate and transplant mouse pancreatic islets to human patients with diabetes.

No extra risk for people with pre-diabetes or type 2 diabetes. University of Sydney researchers aim to help clear up conflicting dietary advice around egg consumption, as a new study finds eating up to 12 eggs per week for a year did not increase cardiovascular risk factors in people with pre-diabetes and type 2 diabetes.

Published in the American Journal of Clinical Nutrition, the research extends on a previous study that found similar results over a period of three months. Led by Dr Nick Fuller from the University’s Boden Institute of Obesity, Nutrition, Exercise and Eating Disorders at the Charles Perkins Centre, the research was conducted with the University of Sydney’s Sydney Medical School and the Royal Prince Alfred Hospital.

In the initial trial, particip...

CHAnGE enables rapid generation of genome-wide yeast disruption mutants and directed evolution of complex phenotypes.

The CRISPR-Cas9 system has given researchers the power to precisely edit selected genes. Now, researchers have used it to develop a technology that can target any gene in the yeast Saccharomyces cerevisiae and turn it off by deleting single letters from its DNA sequence. Such genome-scale engineering – in contrast to traditional strategies that only target a single gene or a limited number of genes – allows researchers to study the role of each gene individually, as well as in combination with other genes. It also could be useful for industry, where S. cerevisiae is widely used to produce ethanol, industrial chemicals, lubricants, pharmaceuticals and more.
