In the mid-20th century, psychedelic research to treat conditions like depression began to take off, yet by 1970 almost all of that work came to a screeching halt. But guess what? It’s back, and access to guided therapy to treat various mental health conditions is becoming a reality. The link to The New York Times article about Roland Griffiths is here.

There's a whole lot of information (and misinformation) out there about depression, as well as debate surrounding how it's treated. In this episode, Sam and Deboki unpack this complex mood disorder that impacts over 300 million people across the globe as well as the effectiveness of SSRIs and the work being done to find better drugs.

The first computer was created in 1945 and came in at double the size of a one-bedroom apartment. Just 50 years later, the architecture of the computer on a chip that measured just 7.44 by 5.29 millimeters in size. And now, computers have gotten smaller and smaller [looks down at Apple Watch]. So how did we go from apartment-sized calculators to the tiny devices we use to look up cat pictures when we’re bored? And just how much smaller can we go?

The question of whether or not life exists on other planets is an important and interesting one. But maybe the more intriguing question is, “what if it does?” In this episode of Tiny Matters, Sam and Deboki chat with science writer Jaime Green about what it would mean for life to exist beyond Earth. Her book, “The Possibility of Life: Science, Imagination, and Our Quest for Kinship in the Cosmos,” is a mix of history, astronomy, biology, philosophy, and sci-fi, and just hit store shelves.

Since the very beginning of the space age, people have been wondering if algae could provide a life support system beyond our planet. From dozens of studies over the last 60 years, we’ve figured out that algae probably can thrive for up to a year in space. But what if we wanted to live permanently on another planet, like Mars? This episode is all about algae: how it shaped early Earth, how we might use it to terraform planets in the future, and how it’s being used in biomanufacturing to hopefully get us away from relying on fossil fuels.

For millennia, humans have looked to the sea to find medicine. Today, medical treatments that come from the ocean have been clinically approved for pain, cancer, and Alzheimer’s disease, and over a dozen more are in clinical trials. In this episode of Tiny Matters, Sam and Deboki are tackling marine natural products—things like proteins, fats, and other molecules that aquatic organisms produce—that humans are hoping to use to treat the diseases that plague us.

Around 400 million tons of plastic are produced annually, which is the estimated weight of all of humanity! Plastic-covered beaches and litter on the side of the road is gross and depressing, but it turns out that stuff is just the visible tip of the iceberg. Plastic breaks down into tiny, tiny pieces that have now been found in almost every ecosystem on the planet—from the bottom of the ocean to mountain ranges in Europe. They’ve also been found in us. This episode of Tiny Matters is all about microplastics and both the molecules that stick to them and the ones they release, like forever chemicals (aka PFAS). Find Imari's upcoming book about plastics here. If you're looking for more info on microplastics monitoring and policy, check out  this episode of Stereo Chemistry from our friends at C&EN.
