A couple more
free audiobooks from
ScienceNews:
Life Hacks.
Robots Revealed.
These are relatively recent productions--within the last year or so.
ScienceNews probably has some older ones that are
free also.
One could wish that these are videos, but crossing the threshold from audio to video would add enormously to the production costs. And the society behind
ScienceNews is apparently a non-profit organization, given the ".org" in the magazine's web address.
Thanks to skinmaan and tubemonkey for the info that led me to find these.
