Scientists discover key ingredient in sexual reproduction
... Because sperm and eggs are relatively easy to extract
from sea urchins, biologists have been studying these small marine creatures for decades. They have long served as a model for understanding fertilization in other living beings, including people. In fact, the vital role that calcium plays in egg a...

How much of the world do we really see?
... everything is just that-an impression. In fact we extract
a few details and rely on memory, or perhaps even our imagination, for the rest. Others have a more radical interpretation: they say that we see nothing at all, and our belief that we have only to open our eyes to take in the entire visible world is ...
