Huge collection of life sciences lessons- all I have used are high quality.

Extensive lessons from hands on inquiry lab at University of Rochester, developed/written with research funds.

"Biologists at the University of Rochester have determined how blind mole rats fight off cancer -- and the mechanism differs from what they discovered three years ago in another long-lived and cancer-resistant mole rat species, the naked mole rat."

Naked mole rats are hairless, blind, underground dwellers that are remarkably impervious to cancer. But why you ask? Well, researchers at the University of Rochester asked that same question and it turns out a cluster of genes, called the INK4 locus, is the answer. This locus, also found in humans and mice, uses that cluster to carry instructions, or encode, for several cancer fighting proteins.
