Get nautilus file manager to edit ID3 tags

So editing ID3 tags isn't integrated into Nautilus, which is pretty stupid since it does display your ID3 tag information... so I searched online and found these nautilus scripts:

but the ID3 editing script requires your mp3 files to be in a certain directory format and filename format... so I edited it to just send the filename you wish to edit, to a GUI ID3 tag editor, kid3... all you need to do is copy the python file into your user nautilus extension folder "/home/(your user name)/.nautilus/python-extensions", then install kid3 (using synaptic or apt-get on ubuntu/debian) and restart nautilus (you might need to go to the command prompt and do a killall "nautilus")

Enjoy!

My beating heart

This past Tuesday I dissected a chicken embryo... I extracted the heart and cut it into small pieces. Then I placed a single piece into an individual well of a 6 well cell culture plate, and added some DMEM + antibiotic media. A few of the chunks I added to an enzyme solution called trypsin which digests the extracellular protein scaffold that holds cells together, then I added some of this cell solution to a well in the plate and added the same growth media.

The next day the heart explants (chunks) were still beating:
