Cell Culture Room Issues

I should not need to send out e-mails like this:

Several issues have come up in the cell culture room lately that need to be addressed:

  • Dirty hoods: The working surface inside of the hood must be sprayed down with 70% ethanol and wiped both *BEFORE* and *AFTER* use.
    • I have noticed that the working surface of one of the hoods has consistently been left dirty with dried media spots and the UV light turned on.  The UV light alone is not sufficient the decontaminate the hood.  Most recently, the surface of the hood actually looked even worse under normal fluorescent light.
    • Bleach left on the metal surfaces of the hood will lead to corrosion.  This is not a reversible process, and the parts are expensive to replace.  Clean spills immediately.
  • Open hoods: The sash on the hoods need to be fully closed for our safety once the UV light has been turned on.
    • I want to preserve my vision and also not grow tumors.
  • Vacuum traps/waste flasks: Bleach must be added to these flasks to neutralize any organisms within, *especially* before being emptied (down the drain with copious amounts of water).
  • Unlabeled PBS & media bottles: If you open a bottle, you are responsible for it.  Unlabeled bottles are effectively a waste of valuable and expensive lab supplies.
    • I do not have confidence in any bottle that has been opened but was not labeled with someone’s initials and dated, and therefore will not use them.  I also cannot tell if anything has been added to the media or not, and again, will not use it.
  • Empty serological pipet holders: It is everyone’s responsibility to refill these when the pipets are running low.
    • With the exception of the 1mL and 2mL pipets, an entire bag of pipets will fit in each compartment.  Please don’t just refill with only enough for you to continue working.
  • Empty 70% ethanol spray bottles: It is also everyone’s responsibility to refill these.
    • Matt and I have made up many bottles of 70% ethanol, ready to be used to refill the spray bottles.  Please use them.

The cell culture room should be kept as clean and orderly as possible in order to minimize the risk of contamination, and to make cell culture work as fast and efficient as possible.  It is therefore the responsibility of every member of the lab who uses the culture rooms to maintain the space, regardless of rank and position in the lab.

MS Outlook

I have only ever used Outlook on a consistent basis twice. The first was during my internship at Amgen, and the second is now here at Children’s National Medical Center.

I tried to use Thunderbird in college, and it worked well in the beginning. Once I started to use Gmail, however, it was clearly less efficient, and since Gmail introduced themes, the AJAX-based webmail interface of Gmail is too good not to use.

I do appreciate Outlook, though, so long as people know how to use it properly.  One very useful feature comes from its integration with a calendar, and the ability to invite attendees to meetings, events, etc.  This was done very effectively at Amgen, and not so much at CNMC.  My PI only just learned how to do that, which is good, but to be honest, the meetings I forget about are not the ones with her.

The things that both Outlook and Gmail do well seem to be related to the fact that while people want tools that will do everything, each specific function still needs to be segregated.  I don’t want to look at my calendar, my documents, and my e-mail all at once — but I do want to be able to if I need, and I want edot be able to switch between them quickly.  I also want to move something from my e-mail to my calendar or my documents easily, with as few dialog boxes as possible.

One annoyance I have with Outlook is is someone send me a meeting reminder as a normal e-mail and not an Outlook invitation, I haven’t figured out a way to easily add that to my calendar without switching between my Inbox view and my Calendar repeatedly.  Of course, as I’m writing this, I just noticed I need to hit Ctrl+Shift+A.  Yup, that will work.  Nevermind.

Master of Confocal Microscopy?

I might not be yet, but maybe someday soon.  It’s now really easy for me to do this, and I can’t figure out if it’s just having had more experience or whether I did some magic to the slides that is making them cooperate with me.  I’ll post some sample images later.  For now, here’s a cell I took a picture of an could have sworn it was 3D on the screen.

Who says pep talks don’t work?

My PI gave me a pep talk about graduate school this morning, and combined with a couple other recent events, it has brought grad school as a possibility back into my future life plans.  It’s irritating that I keep going back and forth on this.  Sorry for the mental vomit that comes below, but it’s part of the reason why I haven’t been able to make up my mind.

Issues to consider:

  • Turns out I’m not half bad at science
  • I’ll most likely be on two papers within the next six months, which is good for grad school and med school; ok for industry, but having only a bachelor’s is a limiting factor there.  means nothing outside of science.
  • I missed working in the lab when I wasn’t doing so Senior year or college
  • I don’t even hide the fact I’m a huge science dork
  • Graduate student stipends are ~$21,000/yr
  • Lab environment and dynamic are highly variable, and people and personalities are important.  also important in an office, which just as limiting in social interaction.  social aspect totally different than working in medicine
  • Could go for dual-degree, but that essentially doubles the time before I actually begin my career post-education.
  • I’ll most likely work 10+ hours days and many “occasional” weekends
  • I’d probably work 10+ hours a day and many “occasional” weekends anywhere I work
  • Graduate school is way less expensive than medical school
  • I’d most likely need at least one post-doc position after graduating in order to gain experience, so +2 or more years
  • Medical residencies are similar, and could take longer
  • If I want to stay in science, the only way to make it a decent career is to get a PhD
  • The only ways I’m going to make a decent amount of money in science are to either run a lab or go into industry.
  • Running a lab involves always chasing money, but I will be my own boss, sort of.
  • Working in industry is more structured, but I surrender more independence.  Pay is higher for the same or less work.
  • I have a bit of security in my current position, minimum one year, possibly up to two.
  • Science: I get to play with expensive toys and generate images like this:
  • HCMV-infected HFF

    HCMV-infected HFF

  • Outside of science, and maybe in industry: I can buy my own toys.

Conclusions:

  1. Medical school is out, unless it’s part of a dual-degree medical scientist training program and I end up with both an MD and PhD.
  2. If I stay in science, everything I’ve done for the last four-plus years is still working for me.  Cons: I will be broke for at least four years.  Risky after grad school.  Can lose funding and enter career limbo.  Need to start applying now.
  3. If I leave science, my options may be limited?  Alternatives: product design consultancy (e.g. Ideo), management consulting (not familiar with the field).  Cons: my experience is lacking, at least from my perspective.  Can be laid off.  Should start applying now.

Recent local abundance of luck

Things haven’t been going particularly well for most of the summer, at least with regard to work in the lab, and I had been fairly annoyed by it all. Some of it was likely due to the fact that I was exhausted from moving from Alexandria to Pentagon City gradually and without the melp of movers, but most of it was the direct result of inefficiencies in the lab finally becoming apparent.

Luckily, I wasn’t alone in my frustration, and consequently, had help from my intern in trying to address some of the issues we were having.

Oddly enough, as inappropriate as venting my frustrations about work at work probably is, it helped a lot, not only to sort o my feelings about it and finding a solution, but I think also made me a little less scary and distant to my intern.

Since then, things in the lab have actually been working pretty well — well, at least until today, when I discovered a problem with the protocol I was using. I can still use some of the data that I generated; just not all of it.

What actually prompted me to write this post was actually what happened to me on the way home — a “no passengers” train pulled into the Gallery Place station and turned into the train I needed, saving me the 10 minute wait for the next train home since it was 8:30 pm.

New lab software!

Disclaimer: this is an extremely nerdy post.

First, a bit of background: to examine the location of proteins and stuctures inside of cells, we can fix and then stain those cells with antibodies conjugated to fluorescent molecules or proteins.  To image these cells at a very high resolution, we use the confocal microscope with a UV and/or laser light source.  This microscope is connected to a  computer so that we can make fine adjustments, improve the color balance, and control the laser settings.  We can do more image analysis on other computers not connected to the microscope using a “light” version of the software used to actually run the microscope.

I haven’t been able to do that on my home desktop because the software, ZEN 2008, was incompatible with 64-bit systems, and so I’ve had to do this either at work, or on my laptop.  However, it turns out a new version was recently released, ZEN 2009, which is compatible with 64-bit systems, and works beautifully.  Hooray!

The only downside is that the microscope sees a lot of use, and often, I can only get time to use it during off-peak hours, e.g. not a weekday between 7am and 6pm — like yesterday, 6pm-9pm.  :(

Maybe I’ll generate some nice images from my data at some point and I’ll be able to do something really nerdy and use my own data as my desktop background.

Selfishness in shared environments

Most of my responsibilities at work in the lab as far as actual scientific work has involved finishing up projects and experiments for papers submitted for publication but never completed by postdoctoral fellows and graduate students before they left the lab.

At this moment, I’m working on two such projects; one of which I am working on with the help of an undergraduate intern who had worked on this same project last year. It would be perfectly fine if the graduate student who had worked on this project as part of their dissertaition had actually made it possible to repeat their experiments, but they didn’t, and I can only describe this behavior as completely selfish douchebaggery.

Proper scientific protocol requires that your work be as well documented as possible such that your results can be independently verified. Independently as in a completely different lab. The expectation of acceptable documentation within the *same* lab, however, extends to the proper documentation and storage of reagents, especially those which are extremely expensive.

This graduate student completely and utterly failed in this. Nothing was documented in enough detail for anyone to exactly dupilicate their experiments, the reagent list was incomplete, and worst of all, very few of the reagents they used could be found. Those that could e found had been improperly stored
And had therefore expired or degraded.

This is beyond frustrating not only because it makes repeating experiments dificult, but because it results in a massive expenditure of time and energy for and experiment that won’t work due to bad reagents. These failed experiments brought my intern to tears today after having worked all of this past weekend and also digging around in the -80 degree freezers last week.

My intern has done an amazing job, and it’s extremely unfair that all of this hard work has been thrown away because this grad student was too lazy to not only properly document their experiments but also properly store their reagents so as not to waste everyone else’s time and significant amount of the lab’s money.

I don’t understand how they got away with it, and I wish there were something I could do about it.
