(A Biologist's) St. Patrick's Day Song
May 24, 2012
I'm resurrecting this nerdy drinking song from last year... As many of you perceptive viewers noticed there were a couple alcohol-induced scientific errors in my last version of this song (gold star, perceptive viewers!) -- so I thought this St. Patrick's day would be a perfect time to correct them. Lyrics: In the year of our lord eighteen hundred and eleven On March the seventeenth day I will raise up a beer and I'll raise up a cheer For Saccharomyces cerevisiae Here's to brewers yeast, that humblest of all beasts Producing carbon gas reducing acetaldehyde But my friends that isn't all -- it makes ethyl alcohol That is what the yeast excretes and that's what we imbibe Anaerobic isolation Alcoholic fermentation NADH oxidation Give me a beer [CHORUS] My intestinal wall absorbs that ethanol And soon it passes through my blood-brain barrier There's a girl in the next seat who I didn't think that sweet But after a few drinks I want to marry her I guess it's not surprising, my dopamine is rising And my glutamate receptors are all shot I'd surely be bemoaning all the extra serotonin But my judgment is impaired and my confidence is not Allosteric modulation No Long Term Potentiation Hastens my inebriation Give me a beer [CHORUS] When ethanol is in me, some shows up in my kidneys And inhibits vasopressin by degrees A decrease in aquaporins hinders water re-absorption And pretty soon I really have to pee Well my liver breaks it down so my body can rebound By my store of glycogen ...

How does the immune system fight off threats to the brain? New U-M research yields fresh insight
Finding of an amplification defense mechanism may help research on brain infections, tumors & autoimmune attacks – and settle a debate in immunology ANN ARBOR, Mich., April 30, 2012 /PRNewswire-USNewswire/ -- Like a police officer calling for backup while also keeping a strong hold on a suspected criminal, immune cells in the brain take a two-tier approach to fighting off a threat, new research from the University of Michigan Health System finds. For the first time, the scientists managed to capture that reaction in action, showing how certain immune cells locked onto a model of virus-infected brain cells, while also sending signals to neighboring uninfected cells to let them know about the immune attack. The findings may ...
