Nickel: the essentials. Nickel is found as a constituent in most meteorites and often serves as one of the criteria for distinguishing a meteorite from other minerals.

What is von Willebrand disease (VWD)? It is the most common bleeding disorder in the United States, found in up to 1 percent of the population. Blood contains numerous proteins that help the body stop bleeding after medical procedures or injuries. One of these proteins is named von Willebrand factor (VWF). People with VWD have low levels of VWF or VWF that doesn't work properly, so their blood doesn't clot properly. Though equally common in men and women, VWD symptoms can be more noticeable in women because of heavy bleeding during menstrual periods and after childbirth.
