From tiny T. rexes to a car-sized sea monster, we revisit some of our favourite stories about predators in their prime, like:

• Smaller tyrannosaur solves decades-long debate about the T. rex
• Among Yellowstone’s top predators, wolves beat out cougars as the top dog
• Bears with us. Tracking grizzlies in B.C.
• Cleveland’s ancient car-sized sea monster had bony fangs made out of its skull
• Wild wolves run for their lives when they hear Big Bad Humans nearby
• Why penguin-eating pumas live closer together in Patagonia

From camping out on 'bird poop island,' chasing down wild dogs in Madagascar, or even looking for bombs in a bog in Ottawa –– no one quite does summer like scientists. This week, we revisit some of the hijinks that Canadian researchers got up to last year as they left their labs to get their hands dirty in the field.

FEATURING:

• Camping out on a remote island with thousands of screaming, pooping, barfing birds
• Dodging lions and mongooses to monitor what wild dogs are eating in Mozambique
• Saving ancient silk road graffiti from dam-inundation
• Prospecting for Second World War bombs in an Ottawa bog
• Technology allows examination of Inca mummies without disturbing them
• Eavesdropping on chatty snapping turtles in Algonquin Park

Quirks & Quarks has been taking your burning science questions for half a century. And while we thought we might have answered every question there is to answer over the years, our listeners proved there are always more fascinating head-scratchers for us to tackle.

Like:

• Are comets eternal?
• In a sauna, what am I sweating out?
• Did dinosaurs produce milk?
• If heat rises, why is there snow on the top of mountains?
• What does a black hole orbit?
• What if we had no moon?
• Why are cat and dog tongues so different?
• Why are robin eggs so blue?
• Why do some animals become mega sized?
• How do animals deal with strong bright UV light?
