Artificial Light at Night Disrupts Cell Division, Research Shows

ScienceDaily (Apr. 20, 2010) — Just one " pulse " of artificial light at night

disrupts circadian cell division, reveals a new study carried out by Dr.

Ben-Shlomo of the University of Haifa-Oranim Department of Environmental and

Evolutionary Biology along with Prof. Charalambos P. Kyriacou of the University

of Leicester.

" Damage to cell division is characteristic of cancer, and it is therefore

important to understand the causes of this damage, " notes Dr. Ben-Shlomo. The

study has been published in the journal Cancer Genetics and Cytogenetics
