The gut microbiome is an evolving and exciting field of research, and as we uncover more about the mysteries of the microbiome, the more we realize its significance in our everyday lives. The vast network of microbiota, spanning thousands of species of bacteria, fungi parasites, and more dictates everything from your immune response to mental disorders to physical health. In this episode, Ally, Matthew, and Adya (and Clarinde in spirit) explore the relationship between the gut, brain, and body and discuss how we can directly improve our mental and physical well-being through gut health.

The return to school and social situations after a long period of awayness can be scary a lot of the time. For many of us, amidst all the joy of being reunited with friends, there's the anxiety that comes with being in these social situations. In this episode, Adya and Matthew cover how the brain deals with social isolation, the post-COVID (and summer vacation) phenomenon that is re-entry anxiety, and ways that you can working through that to be more yourself in social situations.

P.S: we're sorry the audio cut out a bit on a few occasions, something was up with our network as we were recording :(

**We want to make a note that it was only after the podcast was recorded did we realize Gliske’s research had been retracted due to some errors in the study. Some facts mentioned in the podcast that have been drawn from Gliske are therefore theoretical and not definitive:

The bottom line that 1) there are anatomical differences in the cis and trans brain (BNST, central extended amygdala, etc.) and 2) there is not enough research to understand functional differences in trans and cis brains holds true.

As the pandemic rages into its 3rd year, the team examines the often overlooked phenomenon of COVID-somnia, including what you can do to minimize the risk as schools stay closed and work from home enters yet another leg. They also look at the instances of hallucinations induced by sleep deprivation, and why it isn't as rare as many would think.

What exactly does happiness look like? And can we learn it? In this episode, the team dives into the hypotheticals of happiness, what it means to run on the hedonic treadmill, and how to find greater happiness through what psychology and neuroscience have taught us.

In the second of two episodes on Valentines day, Adya, Clarinde, Ally and Matthew dive into what love looks like across cultures, ranging from American cultures to North Tibetan cultures to cultures in Hong Kong here today. They also address the anxiety of being single of valentines day, and offer encouragement and tips on how to cope with the FOMO.
