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.

The Sun’s corona, invisible to the human eye except when it appears briefly as a fiery halo of plasma during a solar eclipse, remains a puzzle even to scientists who study it closely. Located 1,300 miles from the star’s surface, it is more than a hundred times hotter than lower layers much closer to the fusion reactor at the Sun’s core...

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.

The particular dynamics of the instability between the giant planets kept Mars from growing to an Earth-mass planet. Credit: University of Oklahoma

A University of Oklahoma astrophysics team explains why the growth of Mars was stunted by an orbital instability among the outer solar system’s giant planets in a new study on the evolution of the young solar system. The OU study builds on the widely-accepted Nice Model, which invokes a planetary instability to explain many peculiar observed aspects of the outer solar system. An OU model used computer simulations to show how planet accretion (growth) is halted by the outer solar system instability. Without it, Mars possibly could have become a larger, habitable planet like Earth.

“This study offers a simple and more elegant solution for why Mar...
