Pelicans are large aquatic birds with a scoop like bill that is used to filter their food from the water. There are 8 living species of pelicans and they are found from tropical to temperate regions. Pelicans most commonly have pale feathers, but a number of species are darker in color. They do not have any feathers on their face, bill or legs and these areas change color during breeding seasons.

An ACL (anterior cruciate ligament) is one of the four major ligaments in the human knee. It is the ligament that is located between the femur and the tibia (two main leg bones) within the knee. It attaches to the back of the femur, runs through the knee and attaches to the front of the tibia. It consists of two bundles of fibers, called anteromedial and the posterolateral. The ACL prevents forward movements of the tibia form underneath the femur. It essentially keeps the leg in line. It is the ACL, along with the PCL (posterior cruciate ligament) that keeps the knee joint stable.
BPA or Bisphenol A is an organic compound used to make polycarbonate plastics (clear, shatter proof plastics) and epoxy resins (glues and coatings). This compound has the same properties and mimics the effects of the female hormone estrogen. Ongoing research has raised concerns about the safety of this compound, particularly for infants and young children. This research has shown that BPA has a negative effect on fetal and infant brain development and behavior. Due to this concern many plastic products are now labeled as BPA Free. So what does BPA free mean? Read this article to learn more.
The Black Death was one of the worst health pandemics to ever affect the world. It was at its peak in 1348-1350 and is estimated to have killed 30-60% of the population of Europe. The Black Death was characterised by large swollen lymph nodes or buboes in the groin, armpit and neck, which oozed pus and bled when opened. These symptoms where followed by acute fever and the vomiting of blood. During the later stages of the disease the skin of a person would turn black due to haemorrhaging and gangrene. Death usually followed two to seven days after initial infection. It is believed that the Black Death originated in China and spread to Europe via the Silk Road. The plague broke out a number of times from the 1300’s to the 1800’s.
