… sweet potatoes may have reached Polynesia 100,000 years before humans did.

… a new Antarctic expedition will take time off from science to search for Shackleton’s legendary ship Endurance.

… the secret language of cargo ships.

These marks, called load lines, show the maximum load a ship can carry. If a ship is overloaded, the marks disappear underwater. The letters on either side of the circle stand for the ship’s registration authority. BV stands for Bureau Veritas, a Paris-based company that is one of 12 members of the International Association of Classification Societies, which sets and maintains safety standards for more than 90% of the world’s cargo ships. The marks and letters to the left of the circle indicate maximum loads under different climatic conditions, which impact buoyancy: tropical freshwater (TF), freshwater (F), tropical seawater (T), summer temperate seawater (S), winter temperate seawater (W), and winter North Atlantic (WNA).
