Naturalists at Sea
For centuries after Columbus, the flora and fauna of the New World remained a mystery to Europeans. But in the 1600s and 1700s, explorers began to visit and describe what were then considered remote corners of the Earth.

Odd head of seahorse cloaks its sneak attacks
Head shape creates hydrodynamic fake-out for stealth hunting.

The ice of a distant moon
Jupiter’s moon Europa hides a liquid ocean, and conceivably life, under kilometers of ice. The challenge for engineers is how to penetrate that frozen barrier with technology that can be launched into space and operated remotely.

Male zebrafish sex tool stops fin regeneration
Tiny, spiked structures on the pectoral fins of male zebrafish help them hold females steady while mating. However, the structures produce a protein that seems to hinder the fish’s ability to regenerate fins.

The giraffes that sailed to medieval China
Chinese exploration of the world is often left out of Western textbooks (at least it was left out of mine), but for a brief period, from 1405 to 1433, the Chinese under Ming emperor Yongle sent out numerous trade missions that reached as far as present-day Kenya. During the fourth expedition, which left China in 1413, part of the fleet led by commander Zheng He sailed to Bengal in India, where in 1414 they met envoys from the African coastal state of Malindi (now part of Kenya). The men from Malindi had brought with them as tribute giraffes, and they gave one of those giraffes to the Chinese, who took it home.
