Mice in space grow thinner skin and more hair, but how safe is micro-g for humans?

Six mice were spent 91 days on board the Internationals Space Station in 2009, or seven years in the life of a mouse. Comparing their tissue characteristics with mice living in the same conditions, only on Earth, researchers found micro-gravity induces some peculiar biological changes. For instance, the mice’s skin was thinner and their hair grew more. Like humans, mice too suffer from muscle and bone atrophy in micro-gravity, which prompted scientists to consider them as reliable models for studying the effect of living in space for extended periods of time. Previously, human astronauts have complained about skin dryness and irritation and these latest findings seems to suggest that these may indeed be caused by micro-gravity.

How fire burns in zero gravity

In space, of course, you can’t have any fires because there isn’t any oxidizer (i.e. oxygen) to sustain the combustion process. Inside a spacecraft or in the International Space Station, however, things are a bit different. Inside you have the same air mixture as on Earth, but because gravity is millions of times smaller an open flame behaves significantly different.

Aboard the ISS: how to wash your hair in space

Every little thing we hold for granted here on familiar ground and gravity is different in space. Take washing your hair for instance. Expedition 36 crew member Karen Nyberg recently uploaded a video on YouTube which has since gone viral which demonstrates how astronauts aboard the International Space Station wash their hair in microgravity. At first glance, everything’s normal. We’re presented

Russian crafts lands safely on earth – most mice, gerbils and other critters perish aboard perished

In April, the Russian space agency launched the Bion-M craft which carried quite a few mice, gerbils, newts, snails and some microfauna into Earth’s orbit. The experiment was designed to test how weightlesness affect them and how these organisms adapt in the process. The craft returned back to Earth on May 19th in an otherwise safe landing, however most of

3D printing in space might save astronauts a whole lot of trouble

The 3D printing revolution is right around the corner. While we might still be a few years away from seeing such printers for home users at an affordable price, the technology has so far proven itself marvelously, whether we’re talking about jawbone implants, scale on scale mechanized dinosaur parts or extremely fine nanoscale objects. Yes, 3D printing has shown that its a
