Curiosity Killed the Rat

In this episode about the science of siblings, we take a close look at the popular idea that your birth order can affect your personality or who you grow up to be. Are first born children more likely to be natural leaders? Are they more neurotic, having experienced the luxury of undivided parental attention only to be “dethroned” by the birth of younger siblings? Are younger siblings more free-spirited and less conscientious? Is there any actual scientific substance to birth-order theory at all?? In our listener question we talk about cannabinoid receptors – do we still have them even if we never partake in cannabis use? We now have patreon! If you love what we do and appreciate what we make, there is now a way you can show us your appreciation financially! There is absolutely ZERO pressure, but if you have as little as $1/month you can chuck it our way to help us out and show us you appreciate all the time and effort that goes in to making this show.

Have you ever wondered why your room always gets messy, no matter how much you clean it? Why you can't un-break that priceless plate you accidentally dropped? Or if there is anything we can do as individuals to prevent the inevitable heat death of the universe? In this extra long episode, Kate and Matt are joined by Bodhi to talk about entropy, life, and ethics, and how they are all more closely related than you may think. Stick around to the end for our listener question, where we find out why some people cannot stand the taste of certain foods.

This episode, Kate and Matt are joined by legendary science communicator Dr Jen Martin to chat all about her experiences when she visited the coldest, driest, most remote continent on earth: Antarctica. Jen went to Antarctica as a staff member for Homeward Bound (a global leadership program for women in STEMM) and consequently was involved in the (so far) largest women-only expedition to Antarctica. But what kind of temperatures are we talking about? Is climate-change-in-action super clear from Antarctica? What is it like to actually BE there?! Jen, being an ecologist in training, also chats to us about some of the amazing wildlife: penguins, seals, and orcas, oh my!

Joined by our resident immunologist Catriona Nguyen-Robertson, Kate and Matt chat all about Vaccines! How and why do vaccines work to protect us against disease? What happens in the body in response to receiving a vaccine, and how does this help? What are some of the different types of vaccines? And what about the COVID-19 vaccines? Are they safe? Why were they ready so quickly? And why are they an example of some very clever science in action!? This episode’s listener question is about cheese – why does it taste better melted!?

Why do our eyes leak when we feel emotions, chop onions, or get poked in the eye? Do these scenarios lead to the creation of different types of tears? How are tears created? WHY? This episode, Kate and Matt delve into all these questions and so many more, as we chat all about crying. We also tackle a listener question about sweating – why do our palms sweat when we get nervous?

With Valentine’s Day fast approaching, Kate and Matt spend this episode talking about the science of love. What is love? Can science explain all those feelings you get when you fall in love with somebody? Breaking love down into the three phases of Lust / Attraction / Attachment, we delve into some of the neuroscience and biochemistry responsible for love. We also answer a listener question about plants and grow lights… how do they work?

Welcome back, folks, to another season of Curiosity Killed the Rat! This episode, Kate and Matt chat about the idea of perpetual motion, and the amazing machines designed to harness this motion to keep moving… forever! From overbalanced wheels to self-refilling flasks, we take a dive into some of the coolest perpetual motion machines that have been theorised throughout history (…or claimed to be real on YouTube…) and why, realistically, they couldn’t possibly work. This episode’s listener question is about sunsets; why are more spectacular than others?

In a truly spooktacular Halloween special to round out season 1, Kate and Matt are joined by Rosie Arnold to chat about ghosts! Have you ever wondered about the explanations scientists have for ghostly encounters? As Rosie breaks down some theories of human perception, we chat about how humans experience the world and why some humans might feel/ hear/ or even see ghosts. Our listener question keeps us in the spirit… spirit, as we try answer the question: Do EMF meters measure ghost energy?

We have an exciting episode this week feature not one, not two, but THREE awesome guests from the Science Communication program at Unimelb, ready to chat all about some awesome science! Steph teaches us about aquatic apes and tiny bones in our ears. Cat leads us through the solving of the mystery in the link between vultures, rabies, and Voltaren. Wayne chats about how different animals can camouflage... by changing their smell!

Kate then tackle’s this week’s listener question all about IV vitamin treatments… is there science behind the hype?

In this episode, Kate and Matt are joined by physicist Kaih Mitchell to discuss all things Lasers. What is a Laser beam? How are different colour lasers made? How powerful and deadly can they be?

This week's listener question takes a look at how habits are formed and what a person can do to overcome them.
