Space Junk

Mar 31 2010 Published by under Cultural Observation, Streaming videos

tags: , , , ,

Humans and garbage .. after you watch these videos, you'll ask yourself if humans can do anything -- even go into space -- without creating a huge trail of garbage? This space garbage is extremely dangerous, too. For example, 10-gram piece of debris can generate a collision force in space equal to the crash of a car traveling at 100 km per hour. Because of our trashy ways, it won't be long until space vehicles cannot leave earth because of the thickening belt of garbage circling planet.

UV, You See? Black Light Reveals Secrets in Fossils

tags: , , , , , , , , , , , ,, ,


Figure 1. The holotype of Microraptor gui, IVPP V 13352 under normal light. This shows the preserved feathers (white arrow) and the 'halo' around the specimen where they appear to be absent (black arrows). Scale bar at 5 cm. [larger view]
DOI: 10.1371/journal.pone.0009223

This post was chosen as an Editor's Selection for ResearchBlogging.org

It has long been known that when exposed to ultraviolent light, fossilized bones and shells -- and even tissues -- will fluoresce, thus rendering undetectable details visible. But this technique has been used mostly to visualize fossilized invertebrates, and inexplicably, has rarely been used to investigate hidden structures in most vertebrate fossils. But a team of paleontologists recently studied the Microraptor gui holotype using UV light.
