Chromosome aberrations in astronauts

A review of currently available data on in vivo induced chromosome damage in the blood lymphocytes of astronauts proves that, after protracted exposure of a few months or more to space radiation, cytogenetic biodosimetry analyses of blood collected within a week or two of return from space provides a reliable estimate of equivalent radiation dose and risk. Recent studies indicate that biodosime...

Astronauts Must Program Robots

The traditional model for human-robot interaction is at the level of user-interface. For example, given a robot structure (say Robonaut a relatively complex many DOF humantorso style robot) how should the robot be commanded by the human? We propose that for planetary exploration on the scale of Martian or Lunar habitation, a fixed robot/architecture will not be versatile enough for the variety ...

Physicians as Astronauts

2011 urban Canadians. The physician must adapt to these differences and avoid imposing his own perspective. The same is true on orbit, with crews generally of international composition. Risk management Living in a remote area is a health risk in itself: for example, the chances of surviving a major head trauma are several orders of magnitude lower when the nearest neurosurgeon and ICU are sever...

Choroidal Folds in Astronauts.

We read with interest and enthusiasm the recent article by Sibony and colleagues which accurately described the biomechanical etiology of peripapillary wrinkles, retinal folds, and choroidal folds caused by idiopathic intracranial hypertension (IIH). The authors correctly state that chorioretinal folds have been documented in a variety of ophthalmic disorders including the microgravity environm...
