Rethinking the Mars terraforming debate

Posted by in categories: engineering, environmental, space

In late July, Bruce Jakosky and Christopher Edwards published a paper titled “Inventory of CO2 available for terraforming Mars,” which was sponsored by NASA. The paper analyzed the amount of volatiles, primarily carbon dioxide (CO2), on or in Mars currently, and concluded reasonably that there are not enough volatiles available on Mars to terraform it sufficiently for a person to not need a pressure suit. Jakosky is the principal investigator for MAVEN, the NASA Mars orbiter studying the planet’s atmosphere. He and his co-author wrote what is technically an accurate paper, in spite of what was an existing mild controversy over the amount of some volatiles in the soil and regolith of Mars.

The Life Extensionist’s Guide to Logical Fallacies

Posted by in category: life extension

A handy guide to logical fallacies for life extensionists.


When debating life extension, or debating in general, it may happen that participants commit logical fallacies—that is, their arguments contain logically invalid reasoning. In practice, this often means that people incorrectly come to certain conclusions that do not actually follow from the premises; if they appear to follow, it’s indeed because fallacious reasoning was used.

Logical fallacies can be tough to spot, both for the people committing them and for the people listening; rejuvenation advocates would therefore benefit from familiarizing with common fallacies committed during debates about life extension so that they will both be able to detect them in other people’s arguments and avoid committing any themselves.

Light from ancient quasars helps confirm quantum entanglement

Posted by in categories: particle physics, quantum physics

Last year, physicists at MIT, the University of Vienna, and elsewhere provided strong support for quantum entanglement, the seemingly far-out idea that two particles, no matter how distant from each other in space and time, can be inextricably linked, in a way that defies the rules of classical physics.

Take, for instance, two particles sitting on opposite edges of the universe. If they are truly entangled, then according to the theory of quantum mechanics their physical properties should be related in such a way that any measurement made on one particle should instantly convey information about any future measurement outcome of the other particle—correlations that Einstein skeptically saw as “spooky action at a distance.”

In the 1960s, the physicist John Bell calculated a theoretical limit beyond which such correlations must have a quantum, rather than a classical, explanation.

Stem cell-loaded hydrogel boosts healing process of aging muscles

Posted by in categories: biotech/medical, life extension

It’s an unfortunate fact of life that as we get older, our cells gradually lose the ability to heal themselves. Thankfully, at least one aspect of that might be treatable in the near future, if new work from Georgia Tech pans out. Researchers have developed a hydrogel that holds muscle stem cells, and by injecting this near the site of a muscle injury they can get to work repairing it. The team says the technique could be effective at treating injuries in the elderly and people with muscular dystrophy.
