Does circadian rhythm affect accuracy of PCR tests for SARS-CoV-2?

Accurate detection of the virus that causes COVID-19 is a vital component in all containment and mitigation strategies for the current global pandemic crisis. Polymerase chain reaction (PCR) tests are commonly used in hospital and clinic settings because they are highly specific, but false-negative tests are common, up to 30% and particularly in early infection.

Shedding new light on entrainment of circadian clocks

Scientists have been studying entrainment of circadian rhythms as long as they have studied circadian clocks. Entrainment, the process by which internal rhythms are reset in order to match the period of the entraining cycle, has properties that are common across many life forms. Indeed, theory of entrainment is one of the factors that unites the field of chronobiology, with principles that can apply to all life forms.

Discovering the Key to Healthy Lighting

Electric light enabled us to conquer the night, but it has come at a significant cost to human health. Over the past 20 years, light exposure at night, and too little light during the day, has been linked to dozens of serious health disorders caused by circadian rhythm disruption
