Timelapse #2!

Hey there everyone. We have ourselves another shiny new timelapse video! This one is of a yeast genus called Alternaria. This particular isolate we got from Taylor Valley, Antarctica.

The video shuts off sometimes because the incubator we grew these guys in was made for plankton, and as such it shuts off the light at night (too much light can be bad for plants). Also some condensation built up on the inside of the plate making it hard to see, but rest assured, we are working on fixing these problems.

Enjoy!

Roast of Lab Equipment 4

Well it's that time again. The time when we all gather to pay tribute to the hard working equipment that makes our work possible.

Today, we would like to honor the greatest team since Root Beer and Vanilla Ice Cream. Today, we would like to thank the Biosafety Cabinet and the Fume Hood.

We will begin by talking about the more frequently used Biosafety Cabinet.



 The Biosafety Cabinet is our primary sterile area in the lab. Any time that we are working with a fungi sample directly, we do it in the Biosafety Cabinet. Before and after every use we wash it really well with... well what is basiclly the equivelent of super powerful wet naps.

As if someone said, "This is good, but can we weaponize it?"


On top of that, the hood contains a high power ultra-violet light that, when turned on, pretty much cooks any organism still alive.

The Biosafety Cabinet also contains a fan and is designed so that while the hood is open, no outside air can enter. This keeps not only the surfaces around our samples clean, but the air as well. As a result, contamination is significantly lower than if we worked out in the open.

The Biosafety Cabinet in a nutshell. 


Next we would like to thank the Fume Hood.


The Fume Hood is like a reverse Biosafety Cabinet. The Fume Hood does not work to keep contaminants out, but instead works to keep chemicals in. The design of the Fume Hood is pretty similar to the Biosafety Cabinet, but the Fume Hood has a fan that sucks outside air in, and prevents the air inside from escaping uncontroled. This is important because if we are working with hazardous chemicals, we want them as contained as possible.

Like a trap for poison!

For example, one chemical that we work with on occasion is called Beta-Mercaptoethanol, or as I like to call it Deathanol, or just Poison. The "Material Saftey Data Sheet" (MSDS sheet) says, among other things, "Combustable liquid and vapor," and, "Inhalation of high concentrations may cause central nervous system effects characterized by nausea, headache, dizziness, unconsciousness and coma...Exposure to high concentrations of mercaptans can produce unconsciousness with cyanosis (bluish discoloration of skin due to deficient oxygenation of the blood), cold extremities and rapid pulse."

As you can see, it's pretty nasty stuff that you don't want to be breathing. The Fume Hood allows us to do that. 


Biosafety Cabinet and Fume Hood, for your hard work in the name of science we are proud to present you with The Golden Mushroom Award and Haikus written in your honor. 


Biosafety has
way to many syllables
for a good haiku

Thanks to the Fume Hood
the Mercaptoethanol
can't hurt me as much

Time-lapse

All right everyone the moment has arrived!

You will find below our very first yeast growing time-lapse video! This particular isolate is called CRY HAVOC. CRY HAVOC isn't actually an antarctic yeast. It is just a regular everyday yeast, but we use it in a lot of our experiments to compare with the Antarctic yeasts. For example, in our desiccation experiment, we are desiccating CRY HAVOC to learn how yeasts that are not adapted to dry environments fare when exposed to dry environments, and then comparing that with the yeasts that are adapted to dry environments.

But I digress, here is the video. Enjoy!

Cool things to come...

Hey everyone!

Here at Connell Lab, we recently discovered that we are in possession of a time-lapse camera, which is pretty darn cool. We are putting it to use already so hopefully sometime next week, you will be able to see a time-lapse video of an Antarctic fungi growing. If it works well, we might even do a couple more.

In the meantime though, here is just a little taste of what's to come!

Upward Bound

Hey all,

Today we would like to give a very warm welcome to the smart and talented upward bound students who will be helping us out for the next few weeks.

First we have Heidi Ortiz.



Heidi is a senior from Oxford Hills Comprehensive High School. Upon finishing high school, she plans on going to the University of Miami to major in Marine Biology. She is currently doing an experiment on the effects of prolonged light exposure on Antarctic Fungi. Can't wait to see the results!

Next we have Chhayheng Chhoeu, a Senior from Lowell High School. Upon finishing high school, Chhayheng plans on going to college to major in Biology or Premed.



Chhayheng is currently helping Amber out with her study of the Red Tide algae. How awesome is that?

Once again, we here at Connell Lab would like to welcome you both! Here is a picture of a cake to celebrate the occasion.

Horray!

We look forward to working with you!
