Resonetics has introduced the RapidX250 laser micromachining system, developed for universities and corporate research to fabricate microfluidic MEMS and medical devices in a rapid prototype fashion.
Traditionally MEMS devices are fabricated by semiconductor lithography. The Rapidx250 uses a multiwavelength excimer laser (193 nm and 248 nm) to directly fabricate the structures in a single step.
The laser [...]
Welcome back to Cheap Laugh Tuesdays (CLT)! Ahh... Far Side... Classic 
We’ll take a brief break from chemical safety today in order to participate in the “favorite reaction” blog carnival. I first recall learning about the Belousov–Zhabotinsky reaction several years ago when I was working on a story about photos of chemical reactions on display at the University of Wisconsin, Madison. It’s quite possible that I’d [...]

Back in May, Explora!, the local science center for which I occasionally volunteer, referred me to the local public TV station to lead a weekend “Science Cafe”. The discussion subject was lightning and its connection with cosmic rays. Trying to augment my usual hands-on electrostatics program with something perhaps more topical, my mind wandered back [...]
Two videos from my most recent radioactive scavenger hunt in Ukraine’s Chernobyl exclusion zone are now on YouTube. One features a pinhead-sized piece of spent nuclear fuel (pictured at left) that was carefully excavated from under about six inches of soil with the aid of a CDV-700 Geiger counter probe, taken back to our hotel [...]

The American South is widely seen as the most viable US market for new nuclear power plants. Although the “nuclear renaissance” faces serious obstacles in the post-Fukushima world, if reactors are to be put on the grid then the South is almost certainly where it will happen first. Dominion’s North Anna plant, which I visited [...]
