We’re all familiar with clocks that shine glowing numbers at us in the middle of the night, but bioengineers at University of California, San Diego have created an entirely different kind of glowing clock. They made a genetic clock that reliably keeps time by the blinking of fluorescent proteins inside E. coli cells. The clock’s blink rate changes when the temperature, energy source or other environmental conditions change, so it could be used as an environmental sensor. In addition, synthetic biology advances like the gene clock could help scientists manipulate gene expression in the future.

To the best of my knowledge the pterodactyle was a reptile, not specifically a dinosaur.

nah, still has to dump that heat in the environment with that micro fridge. could be using a bigger radiator or sink

"Pint-sized refrigerators can blast much more coolness that the conventional method"
You dont move 'cool energy' you remove heat.

Hmm, I wonder if the "red LED" used to study those wrinkles was your typical high-efficiency InGaAlP version.

Ahh so many items that I could care less about. Not that they aren't important, I just know I'll probably never hear about anyone of these ever again. :)
