NASA says no humans have had sex in space. There’s nothing other than speculation to suggest otherwise. (Well, speculation and a vague sense that we would want to try it, given half a chance.) But you aren’t a total junior-high pervert for wondering. Sex — or, rather, reproduction...

Mutations in the Cacnl1a4 calcium channel gene are associated with seizures, cerebellar degeneration, and ataxia in tottering and leaner mutant mice Tottering and leaner, two mutations of the mouse tottering locus, have been studied extensively as models for human epilepsy. Here we describe the ...
For NASA, available data suggest that lung cancer is the largest potential cancer risk from space travel for both men and women and quantitative risk assessment information for mission planning is needed. In space, the radiation risk is from high energy and charge (HZE) nuclei (such as Fe) ...
Besides needed for space station rendezvous, they keep the capsule pointed in the right direction at flight’s end as bigger engines steer the craft out of orbit. Coming in crooked could result in catastrophe. Read more … “POV: It’s 2030 in Europe and you’re being executed for ...
Clarke in particular figured that there were three main types of spacecraft needed for the exploration of space: Space Ferry, Orbit-to-Orbit, and Airless Lander. Each is optimized for their own particular area of use. More recently, orbital propellant depots and their related tanker ships also...
air for crew in spacecraft or in lunar/Mars habitats. Additional research is needed for optimization such as identifying additional candidate species, growing combinations of different cyanobacteria for synergistic effects, and testing more growth conditions to achieve enhanced biomass and increased ...
Studying stem cells in space and investigating their safety and feasibility for use in cellular therapies is still in its infancy. A full understanding of the effects of microgravity on stem cell growth and differentiation is needed. It is yet to be established whether microgravity induces expansion...
Officials said the small menagerie composed of dozens of individual cages would now be flown to Moscow for more tests. Scientists said the animals were needed because they were subject to experiments that are impossible to conduct on the humans who are currently operating the International Space Sta...
particular disease state for medical and insurances purposes. Precipitants of sickle cell polymerization like hypoxia and dehydration are highly sensitive to environmental factors such as high altitude. As such, data for individuals with SCD in space will be much needed. In doing so, we will ...
