The metabolism of most animals follows a circadian rhythm that differs between the day and night. Mexican cavefish living in constant darkness, lost this circadian rhythm some time ago. In a newly published study in PLOS ONE, researchers compared the metabolic rate of both cave- and surface-dwelling Mexican tetra fish (Astyanax mexicanus). They hypothesized that…

Amazon Prime Air might want to pay attention to this research. Scientists have studied the flight patterns of albatrosses to understand how the animals are able to sustain flight with minimal energy expenditure.

New research provides more evidence of how birds conserve energy by flying in a “V” formation:

Aphids generate energy

Red pea aphids (Acyrthosiphon pisum); Figure from: Valmalette et al., 2012 In 2010, scientists at the University of Arizona¬†showed that aphids can produce their own carotene. No other animals are known to produce this important antioxidant and must therefore obtain it from their diets. Aphids apparently acquired this ability to produce carotenoids from a fungal…
