I see clipmarks is getting spammed.

Badly, I just flagged a bunch of clips selling pet products.

                and ions streaming through space. These particles can
                cause cancer and brain damage, but they can be just as

                in space. The transistors went up on the space shuttle

                astronauts placed them in a test setup on the outside of
                the International Space Station on 22 March. After a
                year, researchers will check how radiation affects the
                transistors' operating voltages and currents.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://spectrum.ieee.org/aug08/6485">A typical transistor is made up of a gate separated
