As the dominant fish species in the perpetually cold waters surrounding Antarctica, icefish are notable for the unique physical adaptations that allow them to live where they do. The temperature of saltwater can drop below the freezing point of freshwater without solidifying, so icefish have evolved a type of glycoprotein antifreeze in their bodily fluids. Some icefish have demineralized bones that make them more buoyant than others. How are some icefish able to survive without red blood cells?

In 1625, the Dutch West India Company decided to build a fort on the southern tip of Manhattan Island, in close proximity to the fur-rich forests bordering the Hudson River. Named Fort Amsterdam, it became the capital of New Netherland and was incorporated as the city of New Amsterdam a few decades later. In 1664, it was captured by the British and renamed New York. The Dutch retook the city in 1673, and before the British claimed it yet again, it was briefly known by what third name?

What unusual floral arrangement was placed near the casket at Rand's funeral?
