From Worm to Man
• arclein"Because of this fundamental similarity between all animals, understanding how a worm assembles its excretory system may very well be relevant to understanding kidney physiology and regeneration in humans," he adds.

Animal's Genetic Code Redesigned
• arcleinWhat makes the newly created animals different is that their genetic code has been extended to create biological molecules not known in the natural world. Genes are the DNA blueprints that enable living organisms to construct their biological mach
How Viruses Infect Plants

Why Giant Bugs Roamed

Life Giving Deep Sea Hydrogen
• arcleinWhen seawater interacts with hot rock and rising magma, it becomes superheated, dissolving minerals out of the Earth's crust. At hydrothermal vents, this superheated energy-laden seawater gushes back out into the ocean at temperatures of up to 400
Early Evolution of Wood in New Brunswick

Exploring the Wild Shores of B.C.'s Great Bear Rainforest

African Crested Rat Applies Deadly Poison
• arcleinThey found that the African crested rat chews the roots and bark of a highly toxic tree, and then smears the lethal mixture on its specially adapted fur. Any animals that attack receive a mouthful of potentially deadly poison. It is the first t
Antimatter belt surrounds Earth

On Apex Predators
