Placenta or Minus… enta

A new review of scientific literature finds that there is no evidence that eating the afterbirth is good for the mother.  It could even be harmful.  Which leads Anthony and Jeff to weigh the pros and cons of ingesting placenta, and wondering how this practice has become so common.  More Details/Download MP3 →


Cave Man Returns

The de-extinction movement is in full swing, which leads some scientists to consider reconstructing the DNA of Neanderthals.  Could that be possible?  And what would a prehistoric humanoid be like in the modern world.  Anthony and Jeff consider the possible ramifications.  More Details/Download MP3 →


Running Man

Dean Karnazes has a rare physiological condition that allows him to process lactic acid more efficiently than other humans and effectively run forever. His list of running accomplishments is truly super human. Jeff and Anthony differ on their opinion of whether running is worthwhile, but both of them imagine what they might do if they could replicate Dean’s unique attributes.  More Details/Download MP3 →


Awesomer Gossamer

Scientists have discovered that getting spiders to ingest carbon nanotubes will cause them to weave spider silk that is even stronger than their naturally strong tensile strands.  This leads Anthony and Jeff to imagine all kinds of potential uses for this amazing new by-product. There is only one problem: how do you harvest spider silk?  More Details/Download MP3 →


Under Age Thinking

Scientists now believe that they have isolated the specific parts of DNA that cause aging in humans.  Which leads Anthony and Jeff to think, if they’ve isolated them, perhaps they can eliminate them…  And if they can eliminate them, can’t we all live forever?  And, like, if we can live forever… what would that mean?!  More Details/Download MP3 →


Iron Chef

A London-based company has developed highly articulated robotic hands, and has decided to use the technology to create an in-home product: stand-alone arms that will cook gourmet meals.  Jeff and Anthony marvel at the innovation, but wonder if chef hands is really the most impressive use of the technology.  Like, what about a tiny Ralph Macchio?  More Details/Download MP3 →


Meet Me in the Uncanny Valley

A new virtual reality startup called Project Elysium aims to give Oculus Rift users the ability to have conversations with their deceased loved ones by recreating them digitally, using pictures, video, and data from their lives.  Jeff and Anthony think this is the technological version of clairvoyant shysterism, but actually stumble upon some interesting use cases.  More Details/Download MP3 →

Embry-Oh No!

Whelp, it’s happening.  Scientists in China have begun genetically modifying human embryos.  While these initial attempts to replace potentially fatal genes with new, safe, designer genes proved unsuccessful, the fact that Chinese researchers are even experimenting on human embryos has caused a stir in the scientific community.  Jeff and Anthony debate whether humans should be playing god in this way, and consider the inevitable Lizard Babies that will result.  More Details/Download MP3 →


Take My Pulse

When his heart was replaced with a constant, flowing artificial pump in March of 2011, Craig Lewis became the first human ever to live without a pulse.  Anthony is eager to disregard his biological heart for science’s improvements – he’d do it in a heartbeat – but Jeff is worried that living life without a pulse might lead to strange existence out of rhythm.  More Details/Download MP3 →


Less is Moore’s

Moore’s Law states that every 2 years the number of transistors on a chip will double.  But some scientists predict that in just 10 years, we will hit the upper limit of Moore’s Law.  Anthony and Jeff wonder what the will happen if we get to the end of the Law and suggest a few ways we might outsmart this presumptive limit.
