you may soon be saying ‘aaah’ to check for cancer

How many times have you been to the doctor and had that stupid wooden tongue depressor stuck in your face?  Dry bland taste and the ever-present fear of splinters – no thanks.  Are they even able to see anything worthwhile?

There may soon be a replacement that could actually be used to screen for oral cancers.  The lab of Dr John X J Zhang at the University of Texas in Austin have created a portable mini microscope with resolution good enough to identify early-stage cancer cells.  Their work was recently published in the Journal of Micromechanics and Microengineering.

a biological robot built to keep you healthy

There is no end to work as a researcher.  Eight experiments running at once, preparing for a lab meeting, reading journal articles.  I guess I can’t complain too much, but I have been pretty damn busy lately, as evidenced by the slight lack of posts recently.

If only I had a little robot sidekick to help me out with things.  May not be too far off if a collaborative project from the Engineering and Physical Sciences Research Council (UK) and National Science Foundation (USA) takes off.  This work, being done primarily at Newcastle University in the UK, aims to create a tiny robot designed to function like a living creature.

Every woman I know has a squirt bottle of hand sanitizer, there are ad campaigns about washing your hand, and Lysol is never not in my kitchen. So much effort to get rid of bacteria. But what if we started using them for good, in the fight against cancer?

In a recent article in the journal PLoS ONE, a group led by Dr. Mark Tangney, of University College Cork in Ireland, has reported the use of genetically engineered bacteria being used to develop better tumor imaging techniques.
