Magnets dim natural glow of human cells, may shed light on how animals migrate

January 9, 2021
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...

Biological and health-related effects of weak static magnetic fields (≤ 1 mT) in humans and vertebrates: A systematic review

August 28, 2020
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...

‘Losing the Dark’: Video Illuminates Threat of Light Pollution

April 29, 2020
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...

The circadian clock and darkness control natural competence in cyanobacteria

April 26, 2020
Taton, A., Erikson, C., Yang, Y. et al. The circadian clock and darkness control natural competence in cyanobacteria. Nat Commun 11, 1688 (2020). https://doi.org/10.1038/s41467-020-15384-9 Abstract 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’re all sensitive to light at night, but some are much, much more sensitive than others

November 6, 2019
by Elise McGlashan, PhD & Parisa Vidafar, PhD on November 5th 2019 in Clocks in the Spotlight 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 that the response of the...

High sensitivity and interindividual variability in the response of the human circadian system to evening light

November 6, 2019
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...
