Our guest this episode once got told off for breastfeeding in a kiddie pool... Join us this week as we talk to Dr. Ellie Syddall, A&E doctor and breastfeeding advocate for her patients and fellow doctors.Incidentally, where is the weirdest place you have breastfed?In this lively and heartfelt episode, we dive into what it really looks like to balance medical training with the realities of raising a young family. Dr. Ellie shares candid stories from her years in A&E—sometimes pumping between shifts, sometimes studying for exams with a baby attached—and the resilience it takes to navigate a system that isn’t always designed with parents in mind. We explore how becoming a mother reshaped her identity as a doctor, giving her deeper empathy for patients and a sharper awareness of how healthcare can better support new parents.From latch struggles to public‑feeding confrontations, we unpack the trials of breastfeeding with warmth and humour, including the myths that stubbornly refuse to disappear—from “you have nipple thrush” to “lanolin is great for sore nipples” Ellie helps debunk each one with evidence, clarity, and the occasional eye‑roll.We also talk about what genuine support looks like, whether you’re a partner, friend, colleague, or a stranger in the supermarket. Spoiler: unsolicited advice isn’t helpful, but turning up with brownies almost always is.Finally, we revisit our own early breastfeeding days, sharing the awkward, chaotic, and unexpectedly joyful moments that come with learning how to use your boobs for the purpose they were actually designed for. This episode is equal parts informative and hilarious—a celebration of the messy magic of feeding babies, the communities that lift us up, and the women who manage to do it all while saving lives on the side.As always if you have questions or suggestions please get in touch!Our email address: Sciencetitspod@outlook.comFollow us on all the socials!Instagram and Tiktok- @sciencetitspodBlueSky - @sciencetitspod.bsky.socialContent outlined and presented by Brenda Finney and Frances Hall.Music from audiojungle.net – Konstantin KasyanovLinks:1.     MiLC – Medics Lactation Community, https://www.facebook.com/groups/480916214609440/2.     IBCLC = International Board of Lactation Consultants3.     The boob remembers! https://www.eurekalert.org/news-releases/6166704.     National Breastfeeding Helpline – (UK) 0300 100 0212, https://www.nationalbreastfeedinghelpline.org.uk/5.     National Women’s Health and Breastfeeding Helpline – (USA) 1-800-994-9662

This episode we do a rundown on the key stages of how breasts develop from the fetus to puberty. WITHOUT trying to spend too much time remembering how much of a horror show puberty was… Anyway, Brenda also found some statements about this process from across the internet and poses them to Frances throughout, and some of them are truly unhinged (Toothpaste?!).

Ever wondered why mammals are called mammals? Spoiler: it’s all about the milk. In this episode of Sciencetits, we venture into the evolutionary origins of the mammary gland. We trace the timeline back to when glands first started secreting nutritious goo and as the theory goes not just for offspring, long before marketing made cleavage a cultural phenomenon.Where did milk come from? Turns out, it wasn’t invented by cows—it likely began as a skin secretion to keep eggs moist (talk about multitasking). Over millions of years, evolution said, “Let’s make this dinner, for the kids” and voilà: lactation.But here’s the kicker—why do humans have breasts that stick around even when we’re not nursing? Most mammals only flaunt them during feeding season. We explore theories ranging from sexual selection (thanks, Darwin) to fat storage and signaling fertility. It’s science, it’s history, and yes, it’s a little cheeky. Tune in for an episode that proves evolution has a sense of humor—and a soft spot for mammary innovation.As always if you have questions or suggestions please get in touch!Our email address: Sciencetitspod@outlook.comFollow us on all the socials!Instagram and Tiktok- @sciencetitspodBlueSky - @sciencetitspod.bsky.socialContent outlined and presented by Brenda Finney and Frances Hall.

This week we dive into the science of friendship and stress. Prompted by a social media post claiming that women’s friendships help them handle stress better, Brenda investigates the origins of this claim—only to discover the cited “recent” study dates back to 2000 and isn’t even primary research.Together, the hosts unpack the “tend-and-befriend” theory, a biobehavioral hypothesis proposed by UCLA researchers that suggests women respond to stress through nurturing and social bonding. The paper, published in Psychological Review, synthesizes findings from psychology, neuroendocrinology, and evolutionary biology, but notably lacks empirical data. Brenda and Frances explore the implications of theoretical models in science, the importance of distinguishing between hypothesis and evidence, and how scientific ideas evolve through citation and critique—this one has over 5,600 citations!With their signature blend of humor and insight, the duo challenge listeners to think critically about what “recent” means in science and how social connections shape our health.

This week Frances gives Brenda a pop quiz on several random topics which caught her eye. From the dichotomy of good and evil in babies to electric animals, here we go!

Welcome Back! We are rested and ready to go after our summer break. We kick off this week with Karin, a toxicologist Frances found synergy with as they kept running into each other at conferences. Our chat just goes to show how different scientific minds impact how we move through the world - but also get sucked in by clever (or nefarious - depending on your point of view) marketing. We cover skincare, muscle care and working out as we age.Also - I do apologise - there may be quite a lot of background noise in this episode - despite my best efforts and AI tool assistance, I couldn't seem to get it all cleaned out!As always if you have questions or suggestions please get in touch!Our email address: Sciencetitspod@outlook.comFollow us on all the socials!Instagram and Tiktok- @sciencetitspodBlueSky - @sciencetitspod.bsky.socialContent outlined and presented by Brenda Finney and Frances Hall.Music from audiojungle.net – Konstantin KasyanovLinks:www.examine.com - Great independent resource for pulling together facts and data about nutritional supplements.

For our last show before our summer break (we should be back in late August/September), we are chatting to @tobytheneuroscientist, who came across the Sciencetits TikTok FYP feed and Brenda immediately knew it would be great to get him on the show. Toby is a PhD student studying dementia at UCL and his social media content is just...*Chefs kiss.We talk to Toby about how he decided to do his PhD, and what he wants to do with his career, with a little advice thrown in along the way.Including the importance of networking and making use of British pub culture in all the right ways!Find him as @tobytheneuroscientist on TikTok and send him some love!Right as we are off for the summer, catch up on all our episodes, leave us a review or send us a note.
