Picture of the day

These are human sperm stained with a method called Christmas staining.

This is a complex staining with: fast red, picrinic acid and indigocarmin.

When I saw these slides under the microscope in our course, medical cellbiology, they gave me that christmasy feeling. And I think they are really pretty and cute, like the balls you hang in your Christmas' tree!

So studying for the last test in the year of 2009 isn't JUST a pain in the ass, I think it is really interesting (not only due to the sperm...).

An update about the last days in Tartu coming soon, meanwhile from the stained sperm and me:

Merry Christmas!
