The Natural History Museum in London recently opened a new exhibit that features mockingbirds that Charles Darwin collected during his travels around the Galapagos Islands in 1835. He observed they were unlike the mockingbirds in other South American regions.

Among many possible environmental factors, scientists have long suspected that certain combinations of nanoparticles contribute to cell damage, aging, and eventually death. That hypothesis has been confirmed in a recent study that observed these ultrafine molecules, some of which can penetrate cell membranes and wreak havoc.¹

A team of French experts in paleoenvironments has discovered algae and several bits of marine life that are completely encased in amber, a hard substance thought to originate from hardened tree sap. Amber is renowned for preserving exquisitely detailed fossils, often of insects.

Genes could be thought of as brick molds, used to construct materials for building the physical structures of living organisms. They carry the codes to help make proteins, which then make up different cells that are combined together to form mega-structures called tissues.

Our cells are amazing places that contain countless molecular machines all working together to perform multiple and important functions simultaneously.
