Choline – again

Earlier we discussed the importance of choline in raising the level of general intelligence among the public. Now a study conducted by researchers from Arizona State University, reported by ScienceDaily, has found:

that a lifelong dietary regimen of choline holds the potential to prevent Alzheimer’s disease (AD). (source: Science Daily)

Alzheimer’s disease is the most common form of dementia and puts a high cost on both individual, their friends and family as well society at large. If choline can play a role in a wider strategy to combat dementia, we have little reason not to do so.

Space habitats: the way of the future?

Matthew S. Williams has written a good and elaborate article about space habitats on Interesting Engineering:

Are Space Habitats the Way of the Future

Williams discusses the basics of orbital space settlement and the major benefits and the important problems associated with this concept.

Coriolis effect

As pointed out in a previous post centrifugation is the method proposed in space colonization literature to replace gravity in orbital space habitats. Though the centrifugal force is the most well-known effect of a rotating object (if not, consider your washing machine for a moment), its sister force, the Coriolis force is less known.

The Case Against Mars

We are, to put it mildly, no fans of the colonization of Mars and instead we favor orbital space settlements. In the video below Simon Whistler of the TopTenz YouTube channel gives a nice summary of the challenges people will face on Mars.

It is not to say that orbital space habitats will be easy to build but given the particular difficulties Martian settlers will face, it will be the better alternative.

Of related interest: Interesting Engineering has an in depth article on the challenges of building human settlements on Mars.
