Anatomy
- Yes gentlemen, size does matter. A team of scientists (all male, of course) showed female participants computer generated, nude male figures with varying penis sizes, body shape, and height, and asked the women to evaluate the figures on attractiveness. They found that penis size did influence male attractiveness, but in interesting ways. Discussed on S01E10.
Animal Behavior
- Chickens can be trained to appreciate human beauty. A group of researchers trained chickens to be attracted to human faces and found that the chickens had the same exact preferences for faces as college students. Discussed on S01E02.
- Dogs align their bodies to the earth’s magnetic field while pooping. A team of German scientists recruited dog owners to carefully examine their dogs while they poop and discovered that while pooping, dogs align their bodies along the north-south axis when the earth’s magnetic field is stable. Discussed on S01E08.
- Bat fellatio increases copulation time. A group of researchers videotaped and carefully analyzed bat mating behavior and found that female bats frequently engaged in fellatio, which strongly correlated with longer copulation time. Discussed on S01E01.
- Tan et al., 2009. Fellatio by Fruit Bats Prolongs Copulation Time. PLoS One.
- Bonus: male bats apparently return the favor. Discussed on S01 Bonus Episode. Maruthupandian et al., 2013. Cunnilingus apparently increases duration of copulation in the Indian flying fox, Pteropus giganteus. PLoS One.
- Goats may or may not be afraid of air force helicopters. It’s unclear. A group of scientists had the Dutch Air Force fly combat helicopters above goats and looked for changes in behavior, cortisol levels, and heart rate in the goats. Discussed on S01E07.
- Elephants yawn and it might be contagious. Might be. A group of scientists videotaped elephants for 47 nights using an infrared camera to determine whether they yawn. The answer is yes (but not that frequently). Discussed on S01E08.
- Octopuses play catch by themselves when they get bored. A couple of neuroscientists decided to record octopuses housed in a tank for around 93 days and observed that they play with tube caps for fun. Discussed on S01E18.
- Cows need to be potty trained too. A couple of scientists wondered if potty training cows will help keep them cleaner and healthier. How did they do this? With electric shocks, of course. Discussed on S01E24
- What’s the deal with birds? An ornithologist was sick of receiving persistent calls for manuscript submissions from predatory journals out to make a quick buck, so he decided to submit his latest “work” to one. In it, he reveals his true thoughts on birds. Discussed on S01 Bonus Episode.
Anthropology
- Making turkeys exercise can teach us human history. A few anthropologists wondered whether human leg bone structure reflects how much we exercise. How did they study this? Make turkeys workout on treadmills and analyze their bones, of course. Discussed on S01E17.
- Chimps recognize each other by their butts. Also, humans are pretty good at recognizing butts. A couple of scientists showed college students and chimps images of female human and chimp faces, butts, and feet, to determine how humans and chimpanzees process and recognize these images. Discussed on S01E21.
Chemistry
- Can you unboil a hardboiled egg? A group of biochemists discovered that hardboiled egg whites can actually be quite easily unboiled. Discussed on S01E12.
- Adding poop to graphene enhances its electrocatalytic properties. A team of innovative material scientists wondered if anything you add to the magical material graphene makes it better, so they tried adding chicken poop. The results? Graphene’s effectiveness as an electrocatalyst doubled. Discussed on S01E23.
Economics
- Expensive placebos work better than cheap ones. Two independent studies showed that expensive placebo drugs work better than cheap ones in reducing pain and in improving Parkinson’s Disease symptoms. A third study showed that Spanish internet users are more willing to believe that more expensive fake drugs work better to treat fake diseases. Discussed on S01E11.

- Do ovulating lap dancers earn more tips? A group of scientists wondered if human estrus is a thing and wanted to find economic evidence for it. Where did they go to conduct their study? A strip club in Albuquerque, of course. Discussed on S01E22.
- Japan’s Phillips curve looks like the map of Japan. An economist noted that when Japan’s unemployment rate vs. inflation rate was plotted, the resulting graph looks almost exactly like the map of Japan, with all four main islands. Discussed on S01 Bonus Episode.
Ethics & Society
- Eating meat objectively makes you immoral. Scientists fed beef to college students and found that afterwards, the students developed more immoral opinions of cows. Discussed on S01E05.
- Ethicists may not be all that ethical. Are ethicists ethical? To find out, a philosopher went to academic libraries to see if people who study ethics were more likely to steal books. Discussed on S01E17.
- The presence of Batman makes people more prosocial. A group of psychologists wondered why pregnant women often do not get offered seats on the subway. Turns out, it’s because Batman isn’t also on the train. Discussed on S01E18.
Food & Cooking
- Is double dipping really unsanitary? Scientists investigated whether double dipping actually contaminates various dips (salsa, chocolate sauce, and cheese dip) with oral bacteria. Discussed on S01E06.
- Kids think bacon is a plant. A team of psychologists interviewed 176 four- to seven-year-olds from an American metropolitan area and found that roughly half of them think that meat come from plants and do not think animals are things we eat. Discussed on S01E09.
- People can’t tell pâté and dog food apart. A team of scientists and food critics wondered if people can tell apart dog food from pâté, liverwurst, and SPAM, so they asked some friends and colleagues to blind taste-test each of these different food items. Discussed on S01E20.
Language & Communication
- Manspreading in photos gets you Tinder likes. A team of psychologists and business administrators found that nonverbal displays epitomized by manspreading are beneficial for people on speed dates and dating apps. Discussed on S01E07.
- Let’s explain mansplaining. Does mansplaining actually exist, and if so, why? Why do men engage in this heinous act? Two female scientists investigated these questions and looked at whether mansplaining can be explained by the better-than-average effect and the interpretation bias. Discussed on S01E16.
- Bees on cocaine dance more exuberantly. A group of apiologists wondered if bees enjoy cocaine as much as people, so they gave bees cocaine and monitored their behavior. The bees did indeed enjoy cocaine, which caused them to exaggerate more when communicating through dance. Discussed on S01E14.
- Zoologists can be a bit sexist when describing female mating behavior. A group of zoologists felt that their colleagues were mis-using the word “promiscuous” when describing animal sexual behavior. They found that other zoologists were much more likely to use the term when describing female behavior than male. Discussed on S01 Bonus Episode.
- Don’t let writer’s block prevent you from publishing. A behavioral therapist had writer’s block and decided to self-treat. It didn’t work. He published the results anyway. Discussed on S01 Bonus Episode.
Medicine
- Teenage boys often pick their nose, and some are ashamed of it. A couple of psychiatrists investigated how often high school boys engage in nose picking using a very comprehensive survey. Discussed on S01E02.
- Shocking yourself with electricity is not a good way to treat venomous snake bites. Case report: a rattlesnake owner and frequent venomous snake-bite victim convinced his neighbor to shock him with a car battery to treat his most recent snake bite. His doctors describe his subsequent hospital stay. Discussed on S01E01.
- Reanimating cadaver arms is a good way to test pumpkin carving safety. Pumpkin carving can lead to serious hand injuries, so a few orthopedic surgeons tried to determine the safest knives to use for pumpkin carving. How did they do this? By carving pumpkins using reanimated cadaver arms, of course. Discussed on S01E15.
- Clowns make really good anxiolytics for kids pre-surgery. Two groups of anesthesiologists examined whether clowns can help calm kids’ nerves before they underwent surgery. The surgeons and surgical teams, unfortunately, did not appear to enjoy these experiments as much as the kiddos. Discussed on S01E21.
- Case report: finding a ladybug on colonoscopy. Some gastroenterologists found an intact ladybug in the transverse colon of a relatively healthy man who came in for a screening colonoscopy. How does that happen? Discussed on S01 Bonus Episode.
Microbiology
- Beards can be contaminated with bacteria, unless you wash them. A group of microbiologists suspected that their bearded colleagues were a contamination risk and devised interesting experiments to test this. The experiments involved a lot of chickens, for some reason. Discussed on S01E05.
- Are farts sterile? Do they contain bacteria? As told by Dr. Kruszelnicki on his radio show, a surgical nurse asked him whether breaking wind during surgery breaks the sterile field of the operating room. Dr. Kruszelnicki investigated this question with a couple of microbiologists. Discussed on S01E13.
Neuroscience
- Roadkill animals might be dumber. A taxidermist with 3500 dead birds teamed up with a zoologist to determine whether birds killed by cars have smaller brains compared to the other dead birds in their collection. Discussed on S01E10.
- Scratching your left arm can relieve itch in your right arm if you use a mirror. A team of neurologists examined whether they can relieve itch in one arm by scratching the other, with the help of mirrors. Discussed on S01E06.
- Dog owners are pretty good at identifying their dogs by smell. Dog owners were asked to distinguish their dog’s odor with that of an unfamiliar dog, and they were surprisingly accurate. Cat owners? Not so much. Discussed on S01E11.
- Pianos taste sweet and brass horns taste bitter. A group of scientists tested whether people’s senses of taste and hearing “cross-streams.” Turns out, they kind of do. Discussed on S01E12.
- Some people dedicate brain cells to recognizing specific celebrities. Some neurosurgeons found that when they showed their patients images of celebrities, such as Jennifer Aniston and Halle Berry, specified neurons lit up. Discussed on S01E16.
Physics
- When you need to drag sheep, choose wooden flooring. Sheep shearing is hazardous, in particular the sheep dragging step. Some scientists asked sheep shearers to drag sheep 400 times across different types of flooring to determine how best to make sheep dragging easier. Discussed on S01E03.
- You don’t swim slower in syrup. A swimmer and an engineer filled a swimming pool with syrup and asked professional and recreational swimmers to swim in it. The methods section is 10/10. Discussed on S01E04.
Physiology
- Swallowed Legos take one to three days to pass. Kids often swallow small toys and parents always worry about how long it will take for the swallowed object to pass. Inspired by the noble history of self-experimentation in medicine, six dedicated pediatricians took it upon themselves to figure this out. Discussed on S01E19.
- Eating garlic makes men smell more attractive to women. Garlic is famous for causing bad breath, but how does it affect body odor? A team of scientists fed garlic to men, collected their armpit sweat, and asked women to rate the smell. The results were quite surprising. Discussed on S01E23.
- Sitting too long on the toilet can cause deep tissue damage. A group of biomedical engineers created an intricate model of the buttocks to study the dangers of sitting on the toilet for too long. They also found that specialized toilet seats can help prevent tissue damage to the butt. Discussed on S01 Bonus Episode.
Psychology
- Drinking fake alcohol makes you find yourself more attractive. Some scientists tricked a group of people into taste testing fake alcohol and discovered that the participants found themselves to be more attractive afterwards. Discussed on S01E04.
- Can you predict who uses iPhones and who uses Android phones? Some psychologists wondered whether there are personality differences between iPhone and Android users, so they conducted a survey. They then took the data and developed a machine learning model to predict who uses what phone. Discussed on S01E14.
- Situations that arouse fear also arouse sexual attraction. A couple of social psychologists asked their attractive female associate to approach single men on bridges. They found that men approached on a scary suspension bridge were much more likely hit on the female associate. Discussed on S01E15.
- Testosterone makes men serve more hot sauce to people. A group of psychologists wondered if playing with a fake gun can 1) increase testosterone levels in men, and 2) make men more aggressive when serving hot sauce to people. Discussed on S01E22.
Sports & Athletics
- Are bearded men better at fighting? A few evolutionary psychologists wondered if beards provide men with an advantage during fights. They analyzed ten years worth of UFC fights to find out. Another group wondered if beards specifically act as a cushion to lessen the impact of strikes to the face during fights. They meticulously measured the amount of force various mammalian hairs, glued to fake human bones, can absorb. Discussed on S01E19.

- Swearing makes you stronger. Across two independent studies, researchers got a bunch of volunteers to perform exercises (wall sit, planking, flat push-ups, and chair push-ups) while saying their favorite swear word. Discussed on S01E24.
Transportation
- Does cannabis use impair your ability to ride a bicycle? A team of scientists wanted to know if marijuana use impairs automobile driving ability, but such an experiment would be unsafe and unethical. So instead of having marijuana users drive a car, they had them ride a bike through an obstacle course. Discussed on S01E20.
