New research led by an astronomer at the University of Warwick has found the first confirmed example of a double star system that has flipped its surrounding disc to a position that leaps over the orbital plane of those stars. The international team of astronomers used the Atacama Large Millimeter/sub-millimeter Array (ALMA) to obtain high-resolution images of the Asteroid belt-sized disc.

The overall system presents the unusual sight of a thick hoop of gas and dust circling at right angles to the binary star orbit...

Your knees and your smartphone battery have some surprisingly similar needs, a University of Michigan professor has discovered, and that new insight has led to a “structural battery” prototype that incorporates a cartilage-like material to make the batteries highly durable and easy to shape.

The idea behind structural batteries is to store energy in structural components – the wing of a drone or the bumper of an electric vehicle, for example. They’ve been a long-term goal for researchers and industry because they could reduce weight and extend range...

High intake of Dietary Fiber and Whole Grains associated with reduced risk of non-communicable diseases

Carbohydrate quality and human health: a series of systematic reviews and meta-analyses
January 10, 2019DOI: https://doi.org/10.1016/S0140-6736(18)31809-9

Observational studies and clinical trials conducted over nearly 40 years reveal the health benefits of eating at least 25g to 29g or more of dietary fiber a day, according to a series of systematic reviews and meta-analyses. People who eat higher levels of dietary fibre and whole grains have lower rates of non-communicable diseases compared with people who eat lesser amounts, while links for low glycaemic load and low glycaemic index diets are less clear...

Targeting an RNA-binding Protein to Fight Aging

Schematic model of PUM2 impact on age-related mitochondrial function. PUM2 expression increases upon aging and this facilitates the capture/trapping of Mff mRNA, either alone or in association with other RNA-binding proteins (RBPs) in Ribonucleoprotein particles (RNP). Consequently, PUM2 prevents Mff translation, impairing mitochondrial fission and mitophagy thereby leading to mitochondrial dysfunction.

Researchers have found that the RNA-binding protein PUM2 contributes to the accumulation of defective mitochondria, a key feature of the aging process. Targeting PUM2 in old animals protects against age-related mitochondrial dysfunction...
