Sleep Debt Needs to be 'Paid Off'

SLEEP that knits up the raveled sleave of care
The death of each day’s life, sore labor’s bath
Balm of hurt minds, great nature’s second course,
Chief nourisher in life’s feast.

William Shakespeare’s lines from Macbeth hold the common opinion that sleep is very important for recuperation, stress management, and a better condition of life. A multidisciplinary study involving eight researchers in the field of medicine, public health, medical technology, and psychology found that sleep deprivation reduces working memory capacity (WMC), and results to increased math, accuracy and speed errors. Previous studies found no serious impact on fine manual skills (e.g. surgery) an acute fatigue due to a 24 or 30 work-hour day without sleep in a four-day cycle.

Of the increased errors observed, those in math... (Read more.)

A RECENT study on macrophages (i.e. defensive cells in our body that engulf threatening substances inside our body) introduced me to a lethal, genetic disease that targets the male population.

While it has an incidence of one in 3,500 newborn males, health experts consider this as the most common lethal disease of childhood around the world. Mutation in the male (X) chromosome [dystrophin gene, locus Xp21] causes a rapid degeneration of the muscles, leading into an eventual loss of walking ability and then death. While females do not exhibit symptoms, they can be carriers of these defective genes, especially if the father had this condition or the mother is also a carrier. Symptoms usually appear before age five; at times visible in early infancy. These symptoms involve... ( Read more .) This article appears in Sun-Star Ce...

“I RECKON being ill as one of the great pleasures of life, provided one is not too ill and is not obliged to work till one is better,” wrote Samuel Butler in The Way of All Flesh (1903). The term “antioxidant” was originally used in the 18th century to refer to a chemical that prevents the consumption of oxygen in laboratory experiments.
