ScienceDaily, 5 January 2021. https://www.sciencedaily.com/releases/2021/01/210105104832.htm First direct observation of magnetic field affecting autofluorescence of flavins in living cells. Summary: New research shows how X-Men villain Magneto’s super powers could really work. Researchers have made the first observations of biological magnetoreception – live, unaltered cells responding to a magnetic field in real time. This discovery is...

Published: June 9, 2020https://doi.org/10.1371/journal.pone.0230038 Abstract Background There is a rapid development in technologies that generate weak static magnetic fields (SMF) including high-voltage direct current (HVDC) lines, systems operating with batteries, such as electric cars, and devices using permanent magnets. However, few reviews on the effects of such fields on biological systems have been prepared and...

A short video seeks to stem the rising tide of light pollution, which is robbing Earth of its dark night skies. Light pollution doesn’t just make it more difficult for professional and backyard astronomers to observe the heavens, according to the 6.5-minute film, which is called “Losing the Dark.” The loss of darkness also disrupts...

Article https://doi.org/10.1038/s41467-020-15384-9 The cyanobacterium Synechococcus elongatus is a model organism for the study of circadian rhythms. It is naturally competent for transformation—that is, it takes up DNA from the environment, but the underlying mechanisms are unclear. Here, we use a genome-wide screen to identify genes required for natural transformation in S. elongatus, including genes encoding...

by Elise McGlashan, PhD & Parisa Vidafar, PhD on November 5, 2019 in Clocks in the Spotlight Image credit: Olivia Walch (Twitter: @OliviaWalch; website: www.oliviawalch.com)  Humans evolved in an environment with only very bright (sun) or very dim (moon or fire) sources of light. Today, artificial lighting enables us to spend hours per day at intermediate light levels. Our recent study shows...

PNAS June 11, 2019 116 (24) 12019-12024; first published May 28, 2019 https://doi.org/10.1073/pnas.1901824116 Significance: Electric lighting has fundamentally altered how the human circadian clock synchronizes to the day/night cycle. Exposure to light after dusk is pervasive in the modern world. We examined group-level sensitivity of the circadian system to evening light and the degree to which sensitivity varies between individuals. We...
