Skeletal muscle in individuals with type 2 diabetes has a different circadian rhythm, research shows

Almost all cells regulate their biological processes over a 24-hour period, otherwise called a cell's circadian rhythm. To do so, cells use a biological clock that cycles different genes on and off throughout the day and night. Scientists already know that our metabolic health can suffer when our biological clock breaks down, due to shift work or sleep disorders, for example. However, it's unclear how exactly the biological clock of people with type 2 diabetes differs from healthy people.

Research uncovers a new human sensory ability to detect sugars in the mouth

Most everyone understands that a major role of our sense of taste is to inform us when sugar is present in foods and beverages by eliciting sweetness on our tongues. A study led by the Monell Chemical Senses Center, published this month in PLOS ONE, identifies a new human sensory ability to detect sugars in the mouth with a molecular calorie detector, of sorts.
