Stem cells that were claimed to be created simply by exposing ordinary cells to stress were probably derived from embryonic stem cells, according to the latest investigation into an ongoing scientific scandal. How that contamination occurred, however, remains an open question. The investigation was instigated by RIKEN, the Japanese research institution where… Read more“Contamination created controversial ‘acid-induced’ stem cells”

A couple of weeks ago, I blogged about a new NASA video showing the relative locations and orbits of the space debris they are tracking.  The assumption here is (and I think it’s correct) is that all this space debris is man-made.  Anything natural approaching from the cosmos is either… Read more“Meteorites and the Space Elevator”

We start off by hypothetically shooting things into the sun, then learn about the latest success from the Indian space program and wind up in Canada – learning about… Read more“Weekend Walkabout – From shooting things into the sun to India to Canada…”

Yes, I said that my next post was going to be on tether capacities and power systems, but that can wait – a new space-elevator themed book is available! Celestial Phoenix is written by new (I think) author A. P. Williams and is available on Kindle at Amazon. Be warned… Read more“Book Review – Celestial Phoenix”
