  • Mediocre writing, annoying delivery

    I tried to like this podcast (I love the subjects!) but as is the bane of other podcasts, the hosts try too hard to be entertaining. Kelly is loud and overly exuberant while Daniel comes across as smug.

  • One of the most entertaining & excellent podcasts

    I was lisenting to the latest episode on parasites and remembering how much I loved parasitology as an undergrad before going to the dark side of biochemistry. I once wrote a paper that argued parasites are a 5th or 6th trophic level because they rely on their hosts to expend the energy needed to extract energy from lower levels and the energy economics of only 10% of the energy transferred up the chain makes them very efficient and leads to these amazingly complex life cycles. So my response ... more

Talking Points

Recent interactions between the hosts and their guests.

Listener Questions #39
Q: What is the current stance on waterless showers and alternative cleaning technologies, especially in space or water-scarce environments?
Waterless or low-water options like dry shampoos, mist-based showers, spa-like sonic cleaning, and real-time recycled water showers are discussed, with caveats about practicality, energy use, and current limitations; the hosts emphasize that while innovative options exist, traditional water-based showers remain easier and more comfortable for most people.
Listener Questions #39
Q: Why not be ambidextrous from an evolutionary perspective, and how common is handedness across species?
Handedness appears to be a widespread trait with a genetic and environmental influence but no single dominant gene; most species show a preference for one side due to brain lateralization and specialization, making perfect ambidexterity uncommon.
Listener Questions #39
Q: Hi Daniel and Kelly, how does muscle memory actually work in the brain versus the muscles themselves, and is there evidence that muscles remember.
The hosts explain that muscle memory involves a combination of motor cortex signals, cerebellar coordination, and possibly changes within muscle fibers, including nuclei, that prime future responses; evidence is mixed and ongoing, with studies in animals and speculative human data showing nerve and cellular contributions to memory-like effects.
Are rural raccoons becoming domesticated?
Q: What is the Latin name of the silver fox?
Vulpes vulpis.
Listener Questions #38
Q: Why is there so much focus on alien size and intelligence, and what physics governs the possible scales of life?
Size is bounded by building blocks and the need for metabolism and information processing; intelligence requires enough computing units and a brain structure that can coordinate across the body without being overwhelmed by thermal noise. These physical constraints suggest humans occupy a reasonable middle ground for complexity and communication speed.
