Robot Controlled Chemical Evolution

Robot Controlled Chemical Evolution, “It’s life, Jim, but not as we know it.”

Glasgow scientists studying Robot Controlled Chemical Evolution have created a robotic system where chemicals can evolve. I read about this in Gizmag, but followed it up with a quick read from the horses mouth at Nature magazine. The featured image (enlarged here) is a picture looking down at the heart of the researcher’s robot. Continue reading “Robot Controlled Chemical Evolution”

Dry Ice In Water

Observing The Reaction Of Dry Ice In Water

I always wanted to try this (put dry ice in water) and last year I got the opportunity. When I bought some meat from Donald Russell it was delivered packed in dry ice (frozen CO2) i.e. solid carbon dioxide. This dry ice was used to keep the meat cool in transit. The meat and dry ice are transported in a polystyrene box which provides lots of insulation. However the heat does percolate a package like this and the dry ice sublimates, but usually there is some left on arrival. If not the meat temperature may rise too high. So I had a source of dry ice.

The first thing I wanted to do as soon as the meat was stored in a cool place was put the dry ice in water and watch it bubble away and the vapour flow out and down the side of the container. I caught it on video below:
