Science Safety Rules
Twice a year, every student in science classes has to be
read the “Science Safety Rules.” Then
they must sign a document saying they’ve been read the rules. This year, I was chosen to take care of the
11th grade. This was my first
encounter with the “Science Safety Rules.”
Some, such as “When diluting an acid, pour the acid into water. Never
pour water into the acid,” are really important. Others are ridiculous. Today, I want to highlight my favorite
section: the safety shower. The
emphasized sections are not mine. This
is from the actual document:
When and how to
use the safety shower
- Shower should be used for fire EMERGENCY only!
- If you (or a lab mate) is ON FIRE, position
yourself (or your lab mate) under the safety shower.
- Pull the handle and a deluge of water will result.
- Flames will be rapidly extinguished.
- The safety shower should
also be used if you suffer a massive spill of a dangerous chemical on
yourself, and need to get it off rapidly.
- However,
in a high school laboratory, this will seldom be necessary.
First of all, I
love that fire EMERGENCY is red and in
capitals. ON FIRE and the parenthetical
(or a lab mate)’s in the next line are great for comedic effect when reading to
the class. The contradiction
between the first line and second to last line is a nice touch. Finally, I don’t remember the last time I saw
the word deluge used in a sentence not written by a poet. (Plus, who knew that a deluge of water would
put out a fire?)
CC Cards
In other news, I got a
thank you card from my cousin, CC, this week.
In true CC fashion, she filled up both inside panels and the back. She has done this with every card she has
ever sent me.
Other Random Bits of
Awesome
I am playing intramural volleyball against the students
this Friday. Uchiteli United had a
practice yesterday and my red, bruised arms reminded me of why I prefer sports
played with your feet. Like…
Soccerfootball! Uchiteli United (which is the name of the teacher team in all of the intramural tournaments) hasn’t had a game yet, but I’ve unofficially joined the girls’ football club to prepare for our matches. However, I have to tone down my playing a bit to play with them and they all flinch whenever I come near them. Apparently, I’m scary. It’s probably the only situation in which I am scary.

The Nobel Prize in Medicine was awarded to Sir John B.
Gurdon and Shinya Yamanaka for "for the discovery that mature cells can be
reprogrammed to become pluripotent." Basically, they found a way to take a
differentiated cell (like a skin cell) and turn it back into a cell that is
capable of differentiating into any type of tissue cell, or a stem cell. Embryonic stem cells, which most people have
probably heard of, are debated upside down and sideways in ethics. Previously, it was thought that embryos were
the only place to find these cells. This
new discovery could pave the way for stem cell research that can take place
without the ethical debate surrounding embryonic cells, which is great since
stem cell research is showing promising developments in treating diseases like
Parkinson’s and Alzheimer’s and in organ/tissue regeneration. Science for the win. http://www.nobelprize.org/nobel_prizes/medicine/laureates/2012/press.html
More Bits: Slime
molds have "externalized
spatial memory" which is kind
of awesome. They can navigate a maze by
detecting areas they have slimed
before. Therefore they do not retrace their "steps."
And One Final Random:
An outbreak of my favorite opportunistic parasite, Naegleria
fowleri, has occurred in Pakistan. This
amoeba normally lives in warm freshwater and feeds on bacteria. It does not need to become a parasite to
survive. However, if you dunk your head
under that water and it gets into your nose or ear, it eats its way into and
through your brain. That’s right. It’s a
brain-eating amoeba. Science fiction
could not have done any better than nature in this case. Unfortunately for those infected in Pakistan,
the case fatality rate is 98% and in the 123 known cases in the US in the last 50 years, only one person has survived.
This is a decidedly less-awesome fact; however the organism itself is
pretty cool.
