Massive floods have been sweeping the globe lately. British Columbia flood of 2021, Pakistan flood of 2022, Hurricane Ian, New Zealand, Las Vegas, Kentucky, Yellowstone National Park flood, and floods in California are all recent examples of such tragic flooding. And many are blaming climate change. But at the same time, we’re also seeing record lows in rivers and reservoirs all around the world. So what’s really going on here? Is the answer Hadley Cells changing? Is it the moisture capacity of the atmosphere?

Do you feel stressed right now? Have you ever had a panic attack upon remembering a deadline at the last minute? It really gets you thinking— Why DO we experience stress and anxiety? In this episode, Dr. Tina Lasisi walks us through the evolutionary function of stress, how different stress hormones affect our bodies, and why some people have completely different responses to the same stressors.
"Why am I like this?" is a show hosted by biological anthropologist Tina Lasisi, and produced by STEMedia, that dives deep into evolutionary biology to explain some of our existentialism or everyday questions about our body.

Subduction zone earthquakes are the largest and most destructive on earth. In 2004 a 9.1 megaquake hit Sumatra off the coast of Indonesia, unleashing a massive tsunami and killing 227,898 people. And in 2011, the Tohoku earthquake struck Japan, killing around 20,000 and triggering the infamous Fukushima nuclear disaster. In the Pacific northwest lurks the Cascadia Subduction Zone, which has been dormant for centuries and is overdue for its next “big one.”
In this episode we’re going to tell you what experts think is the best way to survive this inevitable disaster.

Have you ever wondered why your hair grows out of your scalp the way it does? Maybe you've also wondered why our body hair isn't as dense as most other mammals. It really gets you thinking— Why aren't we as furry as our primate counterparts? And what are the advantages of various textures of hair? In this episode, Dr. Tina Lasisi walks us through why hair varies so much across all humans, how hair is a part of our impressive thermoregulatory system, and the shortcomings of addressing hair variation in scientific literature.

Many people say using cannabis helps them with sleep, nausea, chronic pain and other conditions. But producers have long associated "good weed" with high THC content. Over the last few decades, the THC content in many common cannabis strains has skyrocketed, leaving consumers with fewer options. As we continue to legalize cannabis, will that ever change? Let's explore the future of weed.

Wildfires have been consuming homes at a staggering pace over recent years. In fact, structure loss in these fires has grown by 10,000% in the last 13 years! And as climate change further warms the air and dries out the land, this trend seems to be going the wrong way.
For decades, conventional wisdom has told us that fuels reduction is key to protecting communities. However, the latest research shows that weather actually plays a big role as well. In fact, the vast majority of structures are destroyed in wind-driven fires. Tune in to learn how we’ve been focusing on the wrong problem and what we can do about it.

Was hurricane Ian a perfect example of the way hurricane seasons will change as the world warms? Both climate models and the laws of physics are clear: more greenhouse gasses in the atmosphere means warmer air and oceans, which means more energy for bigger, stronger hurricanes. So why is it that we haven’t seen a clear signal from climate change in the hurricane record over the last century? This episode explores groundbreaking research on this question and looks ahead at what we can expect in the coming decades.

To find out how science and art are intertwined, Out of Our Elements Host Arlo Pérez Esquivel talks to Harvard Art Museums’ Narayan Khandekar, an organic chemist who leads research and conservation activities at The Straus Center for Conservation and Technical Studies, about the tools (including a catalogue of more than 2,700 pigments) it uses to scientifically analyze paintings.
Then, art conservator Liza Leto-Fulton demonstrates how to make paint using pigment and a binding medium. And she explains why, despite technological and scientific advances, the human touch is still an important part of conservation.

On the morning of May 18, 1980, Mt. St. Helens volcano exploded with 500 times the force of the Hiroshima bomb. It was the most destructive eruption in U.S. history. The cataclysmic chain of events killed 57 people and thousands of animals, took out 250 homes, 47 bridges, and 185 miles of highway, and flooded valleys. The mountain’s north side collapsed leaving a yawning crater the size of downtown Seattle. To this day, the crater of Mt. St. Helens volcano remains a place of immense danger and strictly off-limits to the public — avalanches, crevasses, poison gas, and boulders tumbling down the near-vertical slopes are just a few of the threats. But in recent years, the crater has become a place of great scientific interest. Few people realize that the hollowed-out crater now holds the world’s youngest glacier. And it cont...

Have you ever wondered how hail is formed? Or just how big it can get? The largest hailstone ever recorded, the size of a volleyball, fell in Vivian, South Dakota on July 23rd, 2010. Large hailstones often shatter windshields, destroy crops, and can even smash through roofs. And while hail might not terrify you in the same way a tornado or earthquake does, each year hailstorms cause between $10 and $20 billion across the U.S.
In this episode of Weathered, we learn how the IBHS Research Laboratory is using 3D printers, sophisticated potato guns, a sky-diving chamber, and other state-of-the-art equipment to help unravel the mystery of how on earth su...

To understand the dawn of chemistry, scientists can’t use test tubes and flasks: they need an atmospheric observatory, courtesy of a modified Boeing 747 jet. In this episode of Out of Our Elements, hosts Caitlin Saks and Arlo Pérez Esquivel learn all about NASA’s unique SOFIA (Stratospheric Observatory for Infrared Astronomy) mission, and how it was used to detect the first type of molecule in the universe: helium hydride.
Helium hydride’s formation helped launch the chemistry that was needed for stars, which contributed to the formation of the rest of the molecules in our universe, to form. Now, 13.8 billion years after the Big Bang, we have the tools to understand how molecu...

In the 1930s, the US experienced what has been called its greatest ecological disaster, when the dust bowl ravaged the midwest, eroding topsoil, destroying crops, and displacing millions. As climate change exacerbates drought across much of the US in places like Phoenix and the larger Colorado River basin, damaging dust storms and haboobs are becoming more common, leading many experts to ask whether we might be heading into another dust bowl?
In this episode of Weathered, we speak to a leading expert about this growing threat, the various hazards that dust storms pose to our health, and how best to prepare ourselves and stay out of harm's way.

Horseshoe crabs spend most of their lives in the ocean depths. But every May and June, their spindly little legs will carry them 60 miles or more to congregate on sandy beaches up and down the Atlantic coast. Nowhere are their numbers greater than in Delaware Bay. As many as 30 million crabs — a population the size of Shanghai, China — descend on these shores. What are they all up to?

What can we do about our plastic waste dilemma? Out of Our Elements hosts Caitlin Saks and Arlo Pérez Esquivel join chemist Malika Jeffries-EL in her Boston University lab to explore just what it takes to break down familiar plastics like legos and styrofoam. They also learn why plastic isn’t always recycled—even when it does make it into those familiar blue bins.
Biodegradable plastics on the market today may sound like a fantastic solution to our problem. But there’s a caveat: Outside of special composting facilities, they’re difficult to break down and they can still introduce harmful microplastics into the environment.

Does fire affect climate change? What about extreme wildfire behavior?
A fire tornado, or “firenado,” is exactly what it sounds like: a tornado made out of fire… and it is truly the stuff of nightmares. The most famous example occurred when the 2018 Carr Fire spawned an EF3 fire tornado with estimated wind speeds of 143 mph! And as climate change drives increasing wildfires around the planet, it only makes sense that we see more fire tornadoes as well. But, watch to the end of this episode because even though fires are burning more acres each year we have some very good news about climate change and carbon storage of burned forests.

Caitlin and Arlo explore a material that may seem mundane and ubiquitous, but is in fact the backbone of our modern telecommunications infrastructure: silica glass. They visit the Diablo Glass School to discover how chemistry plays an important role in the material’s versatility, and experiment with manipulating glass to change its color, and make it so durable that even hammering won’t break it.
But how does this lead to the internet? To find out, they meet with the Exploratorium’s Desiré Whitmore -- also known as “LaserChick” -- who uses lasers to demonstrate how information can be transmitted through glass, and explains how that forms the basis of an ever-growing global fiber optic network than enables high speed internet communication.

Like this episode of #AnimalIQ? Of course you do, that’s the porpoise of us making it! You should subscribe to Terra 🐋 https://bit.ly/3mOfd77 (Trace takes full responsibility for these terrible jokes)
Dolphins are playful and intelligent sea creatures. Humans are enamored with their smarts. We all know they can jump through hoops, but just how much brain power do dolphins have? Can they recognize friends from strangers? Comprehend basic mathematics? Surely they can’t use a giant underwater touchscreen… can they? (They can!) What can’t dolphins do? You’ll have to tune in to Animal IQ to find out! This week Natalia called Dr Diana Riess a dolphin intelligence expert from Hunter College and Trace called Ph.D student Diana Rocha of the World Cetacean Alliance and Dolphin Encountours to learn more about these precocious porpoises.

Methane is a molecule that causes a bit of a conundrum: On the one hand, it’s a fuel that burns cleaner than coal or oil (it could be a bridge fuel to reach a renewable energy future, some believe). On the other hand, it’s a greenhouse gas that’s 86 times more potent than carbon dioxide, according to the Intergovernmental Panel on Climate Change. Controlling methane leaks and emissions, both climate scientists and activists say, is crucial for controlling global climate change.
Hosts Caitlin Saks and Arlo Perez Esquivel investigate this tricky molecule -- and its dancing abilities -- by tracing it to its source, both in nature and in the city. And they meet with Boston University’s Nathan Phillips and MIT’s Desiree Plata to figure out exactly why this molecule is so efficient at heating both our homes and...
