Siestas & Sleepless Nights: The Science of Sleep - Part 2

This episode dives into cultural sleep patterns, the science-backed benefits and timing of naps, and how circadian rhythms and so-called "sleep pressure" affect night time sleep.
It also covers sex and age differences in sleep needs, the risks of too little or too much sleep, and practical sleep hygiene tips to improve sleep quality.

Sleeping Tight and Why It Matters: The Science of Sleep - Part 1

This episode explores why sleep is SUPER important for body repair, immune function, literally cleaning your brain, and protecting you from diseases like Alzheimer's.
We get into some FUN topics like dreams: why we dream, whether there are any benefits to dreaming, and how sleep is different for different animals.
Give it a listen, and stay tuned for part two!

Going on a Trip: Science of Psychedelics

In this episode, I explore the history, science, and clinical promise of psychedelics. This was actually my Master's Thesis topic so very fun episode for me!
We cover everything from how the psychedelics actually work, by acting brain (serotonin) receptors to increase neuroplasticity (make your brain more malleable), disrupt rigid brain patterns, and increase brain "entropy"... and, more importantly, why those effects may help us treat conditions such as PTSD and treatment‑resistant depression.
The episode also discusses the current clinical evidence (including a critical appraisal of its robustness), logisitcal and ethical challenges, and the importance of use within therapeutic / research settings only.

Cris Cancer: Who is funding tomorrow's cancer cure?

In this episode of Science Savvy, I sit down with Elena Muyo, Scientific Projects & Partnerships Lead at CRIS Cancer UK, to uncover how this unique charity is rewriting the future of cancer research. From dual CAR-T trials in children with leukemia, to a first-in-class lung cancer vaccine, to pioneering treatments for devastating childhood brain tumors, CRIS Cancer is driving science that gives patients options when medicine says “there’s nothing more we can do.”
We talk about the incredible story that started it all, how CRIS selects and funds projects that others overlook, and why every pound donated has a multiplying effect on hope and discovery. If you’ve ever wondered how patient-driven science can change the course of cancer treatment, this is the episode for you.

Genetics of Schizophrenia with Aitana Padilla

In this episode we talk about "having great genes", but also weird ones, ancient viral ones, and even one named after Sonic Hedgehog (look it up!). W dive into how your DNA is more like a script with a dimmer switch than a fixed destiny. From epigenetics and retroviruses to schizophrenia research, stem cells, and the pitfalls of 23andMe, we explore the science written into your genome.
Thank you to Aitana Padilla for coming on the show. Aitana is a neuroscientist in training with a deep focus on the genetics of mental health. She currently investigates how human endogenous retroviruses (remnants of ancient viral infections embedded in our DNA) may influence schizophrenia!

Built to Be Mid: The Evolutionary Problem With Happiness

Welcome to this Science Savvy episode on Happiness. In this episode, I explore what happiness really is from a neuroscience & evolutionary perspective, and explain why it’s a biological miracle that we feel joy at all.
I have a background in pharmacology and biomedical engineering, and in this episode I cover why dopamine gets all the hype (but shouldn’t), how gratitude rewires your brain, why you’re not supposed to be happy all the time, and what Tibetan monks can teach us about brain waves and contentment.
Science Savvy helps you understand the systems shaping your thoughts, health, and behavior. If you're ready to explore your body and brain with a little more clarity, you're in the right place.

Boss?! How our brains make (and break) trust with Dr. D'Amico

In this episode, I am joined by Dr. Katharine D'Amico, a behavioral neuroscientist and President of the The Swala Institute for Applied Neuroscience for professional communication. We explore how your brain rapidly forms perceptions, builds (or breaks) trust, and makes high-stakes decisions.
My name is Carmen, I am the host of Science Savvy. I have a background in pharmacology and biomedical engineering. Science Savvy podcast is all about breaking down the extraordinary science behind everyday life.
In this episode, Dr. D'Amico shares her insights from mentoring over 900 startups and researching how trust and emotion shape behavior in professional environments. This episode covers why first impressions are sticky, how oxytocin builds trust and lowers stress, what role emotions really play in strategic decisions, and how to rewire your habits to make better choices. Whether you're curious about brain chemistry, leadership, mental health, or simply how to make smarter decisions, this episode offers clear and engaging insights grounded in real research.
Also, the cover at the beginning of the episode is from my band! Comment if you recognise it ;)

Building Minds: How Architecture Shapes Our Lives and Well-Being

Welcome to the Architecture and the Brain episode, part of Science Savvy with Carmen. In this episode, I explore how the built environment influences the way we think, feel, and connect with others. With my background in pharmacology and biomedical engineering, I break down the science behind sensory perception and neuroarchitecture, and unpack how it shows up in your daily life.
This episode covers the psychology of shared spaces, the impact of natural light and materials on mood and cognition, and why we’re hardwired to respond to beauty. I’m joined by Antonio, a talented architect, as we explore how thoughtful design can support mental health, foster community, and reflect evolving cultural values. Whether you’re passionate about urban planning, curious about how light and scent influence your brain, or just want to create a more inspiring space, this episode offers clear and engaging insights grounded in real research.
Science Savvy helps you understand the systems shaping your thoughts, health, and behavior. If you're ready to explore your body and brain with a little more clarity, you're in the right place.

PCOS: The Reality Show Where No Egg Wins with Dr. Faris

Welcome to the PCOS episode, part of Science Savvy with Carmen. In this episode, I explore the science behind Polycystic Ovarian Syndrome, a complex hormonal and metabolic condition that affects millions of women worldwide. With my background in pharmacology and biomedical engineering, I break down the mechanisms behind PCOS and unpack how it shows up in your daily life.
This episode features a conversation with Dr. Basma Faris, a board-certified OB/GYN and certified culinary medicine specialist. We discuss why PCOS is not just about cystic ovaries, how insulin resistance contributes to hormonal imbalance, and the ways diet, sleep, and stress management play a role in symptom control. We also talk through the myths, the science, and the danger of wellness misinformation. Whether you're navigating a diagnosis or simply curious about how hormones, metabolism, and lifestyle connect, this episode offers clear and engaging insights grounded in real research.
