Want to listen to a particular story from the show? You can do that here. Just look for the time-code link in the description.

The following program is has been constructed entirely out of scientific materials.
No corporate, industry, government, philosophy, religion or other special interest lobbying effort was involved in its creation.
Sponsorship of the show is generated by a community of its listeners who have no control over the content.
The hosts themselves have only the vaguest recollection of volunteering to be hosts, and were not selected to do so by anyone but themselves.
None of them need your vote, your money, your trust or your time and you will not need to click agree to any form of end user agreement in order to enjoy the content.
The stories you will hear are real accounts from the publications of lab and field notes of scientists engaged in research and discovery.
The only filters between you and the subject matters discussed are the education of the experts generating the information, and the cadences of the hosts delivery in relating that information to you.
If at any point while listening you begin to think too freely, feel free to find a more conventional format of public consumption upon which to dull your senses.
For we have no time for that sort of nonsense here on…
This week in Science, coming up next.

Driving Genes
A research team from UCSD reported the first demonstration of successful gene drive in mammals.
Chemists might have discovered why CRISPR makes mistakes.

Ancient Chinese secret…
Human ancestors might have lived in Asia far earlier than previously assumed.

Dark Matter Hunt
A scientist wants to look at minerals to find dark matter traces.

Ever more evidence for a longer native American history
Ancient tools suggest humans were active in the Americas up to 16,000 years ago.

Dogs Of America
They weren’t from America.

Snorting horses be happy horses

This Week in What Has Science Done for me Lately?!?
“Hello Dr. Kiki, Blair and Justin. Science has been doing a lot for me lately. Multiple sclerosis has been prevalent in my family. I recently had gone to see a neurologist at Mayo Clinic and they checked to see if I indeed have multiple sclerosis myself because I had been exhibiting a fair amount of symptoms. I am still awaiting the test results but I know that science has made progress in the understanding of multiple sclerosis and it is not quite as scary as it once had been so even if I do have it I will be okay because I believe in science allowing me to live a normal life nevertheless with the help of immunosuppressive therapies and so on.
–Logan Fette”

15 minutes to a better brain
Exercise post learning leads to better learning.

Oxygen Teeter Totter
Apparently, oxygen levels did some adjusting prior to reaching levels that were conducive to the explosion of life on the planet.

African origins were a multi cultural affair
It was a truly braided stream of humans.

Asteroidal Planetoids
The asteroid belt might be the remnants of 5 planets.

HIV Vaccine
One of 5 HIV vaccines has successfully completed a Phase 1 safety trial. Next step is to test efficacy of protection.
