How Fasting can Improve Overall Health

Figure thumbnail fx1

Highlights
•Transcriptional response to fasting is robustly rhythmic in liver and muscle
•Lack of food fails to sustain “free-running” conditions of peripheral circadian clocks
•Genes are temporally regulated by the clock and fasting-related transcription factors
•Rhythmic response to fasting is reversible by refeeding

Protects against aging-associated diseases. In a University of California, Irvine-led study, researchers found evidence that fasting affects circadian clocks in the liver and skeletal muscle, causing them to rewire their metabolism, which can ultimately lead to improved health and protection against aging-associated diseases. The study was published recently in Cell Reports.

The circadian clock operates within the body and its organs as intrinsic time-keepin...

A new wave of semiconductors that can be painted on is on the horizon. It bears the promise of revolutionizing lighting all over again and of transforming solar energy. Ornate quantum particle action, revealed here, that drives the new material’s properties defies the workings of established semiconductors.

LED lights and monitors, and quality solar panels were born of a revolution in semiconductors that efficiently convert energy to light or vice versa...

New way Supermassive Black Holes are ‘fed’

A new study finds that some supermassive black holes are ‘triggered’ to grow, suddenly devouring a large amount of gas in their surroundings. Supermassive black holes weigh millions to billions times more than our sun and lie at the center of most galaxies. A supermassive black hole several million times the mass of the sun is situated in the heart of our very own Milky Way.

Despite how commonplace supermassive black holes are, it remains unclear how they grow to such enormous proportions. Some black holes constantly swallow gas in their surroundings, some suddenly swallow whole stars...

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...
