Neonicotinoid insecticides, such as imidacloprid, clothianidin, thiamethoxam and thiacloprid, affect the amount of sleep taken by both buff-tailed bumblebees...
A team of researchers from Germany, Denmark and the United Kingdom has identified circadian rhythms in non-photosynthetic, Gram-positive bacterium Bacillus...
Formerly thought to be ‘junk DNA,’ microRNAs (miRNAs) are small chains of about two dozen non-coding nucleotides. They are emerging as important regulators...
A single letter change in DNA code can potentially decide whether a plant is a lark or a night owl, according to a study published in the journal Plant,...
Wearing blue-light filtering glasses before sleeping creates a form of physiologic darkness, thus improving both sleep quantity and quality, and is related...
A new study published this week in the journal Nature shows that injecting mice with a salt solution (hypertonic saline) leads to the activation of neurons...
