Personalized Smell
Different combinations of genes make people sensitive to different smells.
Age of a Tree
How do you count a tree's rings without cutting it down? (Take a core sample.)
Fresh Rain Smell
Why does it smell fresh after it rains? (Ozone from lightning and bacteria in soil)
Sea Sponge Fibers
The optical fibers of the sea sponge can help improve fiber optic cables.
Worm Regeneration
Studying how flatworms use stem cells to regenerate lost body parts.
Mice Mothers
Vitamin supplements given to pregnant mice affect their offspring's risk for obesity, diabetes, and cancer.
Cold Crabs
Cold-water crab species would adapt better to global warming than warm-water species.
Bacterial Fertilizer
Some bacteria make airborne chemicals that help plans grow, resist herbivores
Disappearing Fish
Fish are smaller and not as prolific as they used to be
Pet Roundup
The difference b/t wolves and dogs; tropical fish hunters with hand nets decimate fish populations
Rodent Road Signs
Wood mice use leaves and twigs to mark their spot and find their way around
Mosquito Dunks
How do those mosquito-killing dunks work? (one type uses a bacterium, the other a hormone)
Mosquito Virus
A virus found in hog wastewater infects mosquito larvae and kills them.
Fire Ant Control
Using phorid flies from South America to control fire ants in the U.S.
Primate Cloning
Humans and other primates cannot be cloned using current techniques.
Animal Research
Fish can feel hooks; chickens can regenerate hearing hair cells; adding the neurotransmitter GABA to old monkey's brains made their neurons as efficient as a younger monkey's
Losing Smell
Some olfactory genes in humans don't work -- meaning we've lost some of our ability to smell
Firefly Flashes
Male fireflies that are better able to reproduce have longer flashes, and females can tell.
Cloned Pigs
Cloned pigs differ from one another as much as pigs bred conventionally do.
