From July & August 2025.

Today's 2 topics:

- 24 hours a day, 16,600 feet above sea level in the high dry desert of northern Chile, the 66 antennas of 1.4 billion dollar Atacama Large Millimeter/submillimeter Array or ALMA receives signals located between the infrared and radio portions of the electromagnetic spectrum. The waves that ALMA receives have a length which is about the same as the thickness of a dime. The pattern of present and missing wavelengths in these signals contains the characteristic spectral signatures of the complex molecules that form the basis of living organisms.

- Humans are moving towards a day when there are space colonies in orbit, on the Moon, and the planet Mars, places where the force of gravity ranges between zero and 38% of what we experience every day. What effect will such different environments have on the regeneration of liver, skin, and other human body organs?
