Cold Animals
How do warm-weather animals survive cold weather zoos? (some adapt, and most are allowed to choose to go to the heated indoors)
Cavity-Fighting Bacteria
Bacteria used to ferment milk can also prevent harmful bacteria from sticking around inside the body
Caffeine Pesticide
Caffeine can act as a pesticide to frogs, snails, and slugs.
Fish, Bugs and Robots
Sweating mannequin, microchips in salmon, and caterpillar bug repellent
Spiny Spiders
Spiny spiders use their yellow stripes to lure prey into their webs.
Ant Civil War
An endangered secretes chemicals that may be turned into a pesticide.
Predicting Evolution
Predicting antibiotic resistance by forcing bacterial genes to evolve in a test tube
Malaria-Proof Mosquitoes

Killer Windows
Turning off building lights can prevent birds from flying into windows.
Food Contamination Test
A biosensor for food poisoning pathogens that works like a pregnancy test.
Evolving Spiders
Female choice is driving evolution in a species of jumping spider in Arizona.

Fly Stress Test
A stress test for fruit flies helps provide clues to the genetics of heart disease.
Primary Colors
Why are there three primary colors? (Three kinds of receptors in the retina)
Stealth Bugs
Bacteria in the gut cover themselves with sugar-- perhaps to avoid detection of the immune system
Therapeutic Eggs
The first steps in genetically engineering chickens to produce protein-based medicines in eggs

A 25-year effort to discover, identify, and catalog every living species on Earth.
Killifish and Pollution
Killifish in a river contaminated with creosote have adapted to the pollution.
Calico Copycats
Will a calico cat clone always be calico? (No, fur color/pattern depends on both genes and developmental factors in womb)
Endangered Clones
Why can't cloning be used to produce more endangered animals? (it can be, after more research is done with domestic animals to perfect the procedure.
Tasting Protein
The umami area of the tongue has a taste for amino acids, the building blocks of protein.
