Could you imagine putting that much energy into growing new bone each year complete with a velvety cover containing nerves, skin, and blood vessels? Although full-grown antlers lose their blood supply and animals scrape the velvet…

Nerves in the mouth and tongue make this amazing feat possible as they can actually stretch to twice their resting length without sustaining damage. Dr. Vogl was quote in CBC News…

New research shows that conotoxin, isolated from cone snail venom, can numb pain. Conotoxin is also reportedly 100 times more potent than morphine at treating…
