2With the widely use of confocal microscopes, scientists are revealing ineteresting interactions between molecules. “Cololization” seems to be the buzz word. However, imaging processing is somehow not something just as you see, i.e. it is not WYSIWYT (what you see is what you think). It is more or less beyond the curriculum of many biologists. Many of my coleagues act in a way that if the two channels have signal in the same region to give another color, that is colocalization. In fact this is a false conclusion. Although confocal microscopy is really powerful, images still are far beyond a direct “yes” or “no”. On the mailing list of CONFOCAL, someone started such a “troll”, and many valuable info is in the thread. Check it out before you do the experiments.

If you’re study biology especially you are an electrophysilogist, you will do statitical tests often, if not daily.  While you are hurrying to find the asterisk between the groups (two? awesome; three? it rocks!), do other people believe that?  Someone at Columbia wrote something interesting on this topic, and complied a beautiful S-shaped curve for us.

APoD just shows a beautiful silhouette of both the International Space Station and shuttle Atlantis with the Sun as the background. A nice shot.

A lot people here around me use M$ Excel for data analysis.  To them it is easy to use.  Although I think it is a pain to use Excel to do statistical analysis when compared with R, Igor Pro, or Origin Pro, they stick to it.  Anyway, here is a list of the essential Excel skills for data analysis from Juiceanalytics‘ blog, whch is a helpful.
