A look back on my life in science, birds, fish, invasive species, streams, dams, and climate change and sleeping lizards.

Where is every one? Why haven't we been visited by alien races, made contact with aliens, or even discovered a hint of an alien race? Ever since Fermi asked this simple question, people have been coming up with answers as to why we don't see aliens. Some solutions are scary, but I think a potential answer could be found by looking at our own solar system.

I believe humans are special and improve our chances of surviving as a species, I explain why we should colonize the solar system and beyond.

I explore how the Silurian Hypothesis provides insight into what it takes for a planet to host or evolve a civilization, how we might detect them, and the legacy of humans on Earth.

After 6 months, I'm back! I talk about how some of my views have changed to become more nuanced and how my own biases shape the way I think about astrobiology.

In researching astrobiology for my up coming book, I've started to view the evolution of life and civilizations in a paradigm shifting way that challenges the very basics of our understanding of evolution. Listen in as I explain why I think evolution is progressive.

What makes animals different from all other organisms? I discuss the evolutionary origins and unique features of animals along with a few other fun facts. And find out why I don't think sponges are animals.

The more I learn about plants, the more I'm amazed. From insects to fungus and bacteria, plants form many relationships. Some plants even talk to each other through the air or underground, while others form three-way relationships with ants and fungus.

Tatooine, Dagobah, Hoth, or the Death Star, how Star Wars resembles our solar system. I couldn't help myself, I had to do an episode comparing our solar system to my favorite movie. Learn how the Earth was like Mustafar. (Yes, I did say wookies were on Endor, Ewoks were supposed to be wookies)

From the nature of light, to the light reaction and through the Calvin Cycle I explain how photosynthesis works. I cover how light energy transformed into chemical energy and follow the electrons from water to the Calvin Cycle.

After a few memes with cats sitting on biology books making references to biology being soft and textbooks calling chemistry the central science, I figured it's time to start calling biology the Apex Science, or the apex of science. Drawing from my own experience, I explain how biology is special because it incorporates almost every other field of the natural sciences, putting it at the top

These are some of the biggest discoveries, events. and breakthroughs of 2022, from huge volcanoes, long-lived bacteria, breakthroughs in cancer treatments, AI, and why the James Web Telescope is one of the most important things we have done as a society.

How we do science is changing. I use my own  experiences from graduate school to understand science and where it is going from question driven science to the importance of natural history and keeping up with Artificial Intelligence.

Can one number be used to rank a civilization's advancement? I discuss the Kardashev Scale and how we might expand upon it by looking at other measures of advancement beyond energy use.

Do you have mutant super powers like eating ice cream without it hurting your stomach? How can diet and exercise slow down aging, or why do age in the first place? Does what happen to you affect your children? How do we make more proteins than we have protein-coding genes for?  Lastly, how can two black labs have both chocolate and yellow lab puppies? We can find answers to these questions by knowing how our genes are regulated. I discuss gene regulation including operons, alternative mRNA splicing, epistasis, and epigenetics,

Why are some cancer cells immortal? What can we learn about aging from a lobster? Why does a gene from a human work in a bacteria? The answers lies in genetics. In this episode I explain how understanding the basics of DNA replication, the genetic code, and mutations improves our lives from treating cancer, slowing aging, to making medicines.

Why do we reproduce sexually, why do we look similar to our parents and siblings, but are different? In this episode, I take a close look at the origins of sexual reproduction, how meiosis generates genetic diversity, and Mendel's basic principles of inheritance.  One of the major themes in my classes is that biology is complicated, and that goes for genetics so I also discuss  extensions to Mendelian genetics. And lastly, I explain several common misconceptions about inheritance.

Why is the outer solar system perhaps the best place to look for life?  If it is, then where should we look for it? And importantly, what would it mean to find life in our solar system?

For hundreds of years, we have wondered if life is on Mars. I take a close look at the evidence from nearly 50 years of orbiters, landers, rovers, and even Marian rocks found on Earth to answer this question. The evidence is compelling!

Surprisingly, defining life is hard. Listen in as Tom Kennedy takes a broader look at what makes something living.
