Free radicals may be good?
An important reminder that our current view of scientific ‘truth’ is always a rough draft.

Biology education
I’ve been thinking about this recently. Should biologists, specifically those in the molecular biosciences, focus on biology at the undergraduate level? Modern cell and molecular biologists benefit from rigorous training in chemistry, mathematics, computer science and physics. Most don’t get good training in these disciplines in high school. In college, students take just enough courses in these topics to graduate. The problem is that few folks are willing (or able) to teach themselves calculus or physical chemistry. For good students, it’s relatively easy to go back and learn the biology.
Are we hamstringing new biologists by letting them focus so much effort on biology?
…and another beautiful video from the BioVisions folks.
An excellent summary of many subcellular processes. The problems with animations is that they are often simplified to the point of being untrue. The folks at Harvard have gotten things right in this video.
Who's heard of exosomes?
This is one of the reasons I became a cell biologist. There are many great mysteries about the fundamental workings of eukaryotic cells.

epigenetics
Can events that happen in your life directly affect gene expression in your offspring? The answer appears to be yes, although there are many things to learn.
