Anthracite Coal First Burned as Residential Heating Fuel (1808)

Anthracite is a compact variety of coal that was first burned as a residential heating fuel in the US by Judge Jesse Fell in Wilkes-Barre, Pennsylvania.

When in Control of Epidural Dosage, Women Use Less

More than half of women in labor opt for epidural anesthesia, a type of anesthesia that is delivered directly into the spine to numb the lower half of the body, reducing the pain of childbirth but also increasing the risk of an instrumental delivery, meaning that doctors must use forceps or a ventouse to help deliver the baby's head. A recent study, however, found that women given a hand-held controller so drugs could be delivered when needed used approximately 30% less anesthetic and required fewer instrumental deliveries than women who received a steady infusion of drugs.
