Researchers have now created the first simplified computer model of the process that forms the Fåhræus-Lindqvist layer in our blood -- a model that could help to improve the design of artificial platelets and medical treatments for trauma injuries and for blood disorders such as sickle cell anemia and malaria.
Some time around 37,000 BCE a massive volcano erupted in the Campanian region of Italy, blanketing much of Europe with ash, stunting plant growth and possibly dooming the Neanderthals. While our prehistoric relatives had no way to know the ash cloud was coming, a recent study provides a new tool that may have predicted what path volcanic debris would take.
