Intermittent Fasting Linked to Vastly Increased Chance of Heart Attack and Stroke

Posted by in categories: biotech/medical, health

This regimented approach to dieting has helped many people achieve the discipline they need to lose weight, and some research has shown that it can provide a myriad of health benefits, including improved blood pressure.

But a new yet-to-be-published study, presented this week at a meeting of the American Heart Association, suggests that intermittent fasting could have serious consequences for your cardiovascular health.

In an analysis of over 20,000 US adults, the study found that those who eat in just an eight hour window or less per day — thereby fasting for at least 16 hours — had a 91 percent higher chance of dying from heart disease.

Unlocking the Secrets of Space Chemistry With Cold Coulomb Crystals

Posted by in categories: chemistry, particle physics, space travel

Researchers at the University of Colorado Boulder have developed experiments to replicate the chemical reactions of the Interstellar Medium, using techniques like laser cooling and mass spectrometry to observe interactions between ions and molecules.

While it may not look like it, the interstellar space between stars is far from empty. Atoms, ions, molecules, and more reside in this ethereal environment known as the Interstellar Medium (ISM). The ISM has fascinated scientists for decades, as at least 200 unique molecules form in its cold, low-pressure environment. It’s a subject that ties together the fields of chemistry, physics, and astronomy, as scientists from each field work to determine what types of chemical reactions happen there.

Now, in the recently published cover article of the Journal of Physical Chemistry A, JILA Fellow and University of Colorado Boulder Physics Professor Heather Lewandowski and former JILA graduate student Olivia Krohn highlight their work to mimic ISM conditions by using Coulomb crystals, a cold pseudo-crystalline structure, to watch ions and neutral molecules interact with each other.
