Oil Droplets turn Cells into Tiny Lasers

in science on (#10FMD)
Scientists have turned individual cells into miniature lasers by injecting them with droplets of oil or fat mixed with a fluorescent dye that can be activated by short pulses of light. This finding could help to broaden how light is used for both medical diagnosis and treatment. The system was devised by Harvard Medical School scientiest, and it uses droplets of fat or oil within a cell to reflect and amplify light, generating a laser. Conventional luminescent probes, which include fluorescent dyes and proteins, have relatively broad emission spectra. This limits the number of probes that can be used simultaneously, because it is often difficult to distinguish these sources of luminescence from the broad background emissions of naturally occurring molecules in tissue.

complains I have JS disable
For Firefox, go into about:config and set:
accessibility.blockautorefresh to true

Lots of sites are doing nasty stuff with meta redirects, so changing that setting is a good idea. You can still click on the pop-up notice if you want to follow it.
suggests I might like to download NETSCAPE... how old is that site???
They have a banner for Netscape 7.1, which was released in 2003-2004. Yeah, the site is a bit crufty, but I'll take that over the likes of Forbes' shiny new site that breaks if you have ad blocking enabled.
