Sexist birds and intimidating runners with hills

Does the sex of the bird affect how soon they fly away when approached by humans? What about the sex of the human? Coming across a steep hill while out jogging can be intimidating. Does being tired affect how runners perceive the size of hills? In this episode, Lu and Tirth discuss how European birds are sexist towards humans and how just tricking people into believing they have to climb a hill can cause them to exaggerate its steepness.

Kids vs traffic and food preference in fetuses

Crossing the street alone is a difficult and dangerous task for young kids. Is it even more perilous for overweight and out-of-shape children? Kids are notorious picky eaters. When does this start? In the womb? In this episode, Lu and Tirth play another game of Family Feud But Science and discuss practical athleticism in overweight children and whether fetuses are picky "eaters."

The ideal booty call and a potent jet lag drug for hamsters

What do men and women look for in an ideal partner for a one night stand, friends with benefits relationship, and marriage? What’s the best way to find out? An economics experiment, of course. Do hamsters experience jet lag? Do hamsters respond to Viagra? Does Viagra cure jet lag in hamsters? In the season 2 premier, Lu and Tirth catchup on all the life changing events that took place during the offseason and discuss giving people “mate dollars” to build their ideal mate and using Viagra to treat jet lag in hamsters.
