Study: Circadian Rhythm Gene Variants Increase Risk of Migraines from Financial Hardship

Migraines take a toll on around 1 billion people. This work by Baksa et al. indicates that individuals with certain gene variants in the CLOCK gene, which is involved in circadian rhythms, are at a higher risk of migraines when they are exposed to financial hardship.

Researchers have shown that financial stress may cause more migraines in individuals with variants in the circadian rhythm gene CLOCK, suggesting that the genetics of circadian rhythms and presence of chronic stresses interact to influence the likelihood of migraine problems. Migraines take a toll on around 1 billion people. This work by Baksa et al. indicates that individuals with certain gene variants in the CLOCK gene, which is involved in circadian...

The Trachilos footprints were discovered by Dr. Gerard Gierlinski, a paleontologist at the Polish Geological Institute, by chance when he was on holiday on Crete in 2002. Dr. Gierlinski identified the footprints as those of a mammal. In 2010, he returned to the site together with Dr. Grzegorz Niedzwiedzki, a Polish paleontologist at Uppsala University, to study the footprints in detail. Together they came to the conclusion that the footprints were made by hominins. Image credit: Andrzej Boczarowski.

This painting depicts an asteroid slamming into tropical, shallow seas of the sulfur-rich Yucatan Peninsula in what is today southeast Mexico. The aftermath of this immense asteroid collision, which occurred approximately 65 million years ago, is believed to have caused the extinction of the dinosaurs and many other species on Earth. Shown in this painting are pterodactyls, flying reptiles with wingspans of up to 50 feet, gliding above low tropical clouds. Image credit: Donald E. Davis / NASA.

A chemically termolecular reaction is a reaction where three different molecules (e.g. H, O2, H) each participate in the breaking and forming of chemical bonds. The reaction is mediated by an ephemeral collision complex (HO2**) formed from the collision of two molecules (H, O2) which then reacts upon colliding with a third molecule (H).
