A scientist's perspective - Animal rights
Warning: Science rant approaching.
A couple of weeks ago the flavor of the day was an animal rights group handing out pamphlets about animal research. At first I walked past, but on my return trip I took a pamphlet out of curiosity. It was far from well designed, but it got their points across I suppose. The gist of the message was that animals used in research are lonely, mistreated, and abused. Additionally, they are unnecessary due to "alternative research methods." I want to clear this up. There is no adequate alternative research method. None, nine, zip. Yes, we can test new drugs/antibiotics/etc. on cell culture. Yes, we know a lot about biochemistry and drug metabolism and gene networks. And yes, we can make predictions based on that information. Predictions. If you wish to be treated with a drug that is predicted to work, by all means, have at it. I won't even get started on studying diseases in animals. That's a whole other story.
So here's the deal. Say someone has found a new chemical that they suspect might treat cancer based on the chemical structure, it's similarity to previously developed drugs, and a fancy computer system that analyzes potential drugs and drug targets based on decades of research. The next step is to test it on cell cultures. For non scientists, a cell culture is generally a single cell type that has been immortalized, which means they will continue to grow (read: replicate) in the laboratory indefinitely as long as they are provided with appropriate nutrients. Cell cultures are generally created from cancerous cells as growing/replicating is what they do best. So while these cells were originally liver cells, or heart cells, or brain cells, they are not normal cells. This is because healthy cells don't generally like to grow and replicate outside their normal environment (i.e. the human body). Cell cultures can tell us a lot about what a new drug might do in the body, but I stress, might.
See, cell cultures don't have liver enzymes and all sorts of other bits of human biochemistry. A lot of drugs do one thing in cell culture, but something completely different in the human body because the human body is complex. The human body is not just one cell type. When you eat something, it goes to your stomach which is highly acidic. Well, a pill you swallow follows the same path. The acids in your stomach may modify the drug or change how it works. Likewise, your liver's primary function is to take up foreign chemicals and process them. Often, this means the liver enzymes will modify the drug you just swallowed in an attempt to get rid of it, but sometimes this has side effects. For example, part of the process for getting tylenol out of your body is for the liver to modify it to make it easier to get rid of. As a side effect, a fraction of tylenol is changed into a chemical called NAPQI which damages healthy cells. Normally, the liver can handle the small bit of NAPQI and get rid of it too, but if you take too much tylenol, you produce too much NAPQI and this can cause liver damage. This effect would never been seen in a cell culture, however, as they do not have livers and would not make that byproduct at all.
Animal use in research is highly regulated, though these regulations differ by country and (to some extent) by institution. I will say that my experience is academic. I don't know the procedures in the industrial setting. In academia, however, you can't simply say "I wonder if..." and go inject chemical X into a bunch of mice and see what happens. It is a weeks long process of writing proposals, justifying the experiment, and providing background information to a panel of reviewers consisting of community members, veterinarians, and other scientists and waiting for approval. In addition, there are strict regulations on how animals are treated designed to minimize pain and discomfort. Unfortunately, animal research is necessary in order to provide any reasonable sense of security in chemical testing and even more necessary in studying disease and infections because human beings generally don't like being test subjects and they are too damn complex anyways. So yes, animals are cute. Yes, they feel pain. Yes, I've killed mice in the name of science. No, I don't enjoy it. But there is currently no alternative to using animals in research.

Bike lanes
When I first arrived here and was biking to campus to meet professors, etc., I was constantly warned about biking in the city. One of my professors saw my helmet, practically shuddered, and commented that at least I had the helmet and to be very careful. I shrugged off their comments as those of people who don't bike and only hear the horror stories. I saw billboards for bike activists trying to improve biking in the city and figured I don't have time to take up another cause at the moment and they are probably exaggerating.
Fast-forward a month (which I suppose is rewinding a month now as I write this belatedly). I headed out of the house on a rainy day expecting to take the T (public transit = T) to work but when I stepped outside the rain let up and it was actually fairly nice. I knew if I went back inside to grab my helmet the rain would return because that's simply how life works, so I decided in a moment of haste to forgo the helmet just that once. Of course, I was nervous as hell biking to and from work even though there are bike lanes along my entire route. I simply don't trust drivers.
So the end of a long day I'm heading home, in the bike lane, and of course now it's rainy and wet and cold. I'm distrustfully watching traffic like a hawk but that does me little good when the driver of the the SUV parked along the bike lane, who must have been just hanging out in his car for a while, opens his door at the last possible second before I pass by. My bike hits the V made by the door and his car, and my momentum plus the force of the door opening throws me into the car lane where I landed rather painfully on my knee. Thankfully, no cars were currently careening past and a couple good bruises and surge of aggression were my only ill effects. The second of which waned upon returning home and pouring a glass of whiskey.
A week later on a bright and shiny day I'm late for a meeting at work and biking as fast as I can when the door of a parked cab opens unexpectedly. The problem with cabs is that in the time it takes the passenger to pay before exiting, any bikers coming upon it don't have the visual ques of seeing it park or flashing tail lights to note that someone might be exiting the vehicle. So the passenger opens the door right across the bike lane and I swerve nearly enough to avoid it. Nearly. The door caught the handlebar just above the grip, shattered my gear shifter and ripped the grip clean off. Again, I found myself sitting on the road, though in the bike lane this time. I wasn't hurt, having had enough time to almost stop and only being clipped by the door. In fact, I remember scowling and mumbling "seriously?" as I gracefully landed on my ass. A passerby picked up my grip and I replaced it, not noticing how badly damaged the shifter was at first. The taxi driver very sincerely grasped both my hands and asked me repeatedly if I was ok, apologizing at least three times that I recollect. He was so concerned I couldn't really be mad. I picked up my bike and rushed off but was still in earshot to hear the driver begin chewing out his passenger. I hope he had already been tipped.
I'm even more careful while biking lately. And now I wonder at the logic of bike lanes that don't extend past the reach of an opening car door. However, I'd still rather bike than take the T or walk, or deal with driving in the city. So, *shrugs*. And as a side note, here's a picture of my bike. I've cleaned it up a bit since this picture, so imagine less rust.

The road is home
Since I arrived in Boston I've been planning to rent a zip car and get out of town for a day, explore Massachusetts a bit and indulge my wanderlust. So last Saturday at 7am, fresh from a short nights sleep after a long exam and a long days work, I hopped in a bright red Ford Escape and headed North.
Halibut point |
I took longer than planned to get out of the city as I was bent on avoiding highways. Apparently, this is a bad idea at least within the chaos that is urban life. I did eventually find my way to winding seaside roads, however. I perused a library book sale, bought pumpkins, walked along the waves. My main goal, beyond my wander-fix was to scout potential highline and waterline sites to appease my slackline addiction. I did find one potentially amazing site, an old quarry with sheer man-made edges dropping off into deep water. Unfortunately it is protected land and far too public regardless. I guess I'll have to take another scouting trip soon.
Not for the first time, I noted something interested, however. Like initials carved into trees or in more frustrating cases, carved into Stonehenge and Greek temple pillars, we humans seem to have this undeniable urge to mark our territory, to anonymously announce to future visitors that "I was here." In this case, however, the markers made me smile.
I hadn't been myself for the past couple weeks. Exams, work, and trying to continue my slacklining, photography and life in general can be a bit exhausting. Lack of sleep had caught up with me. But on those winding roads draped in autumn leaves, I felt at home.

These city lights
I'm tired, I haven't much to say. But I was biking home from dinner at a friends house tonight and had my camera with me. I grabbed a few shots along the river and wanted to post one before the thought gets lost in my to do list.
A long aimless photo walk is on that list. Fortunately and unfortunately, due to a dinner date with a long lost friend (the fortunately part) and an upcoming midterm exam (the unfortunate, of course) it will have to wait for the weekend.

This is the life and you are you
The view from my bridge |
I'm intrigued at how fast my mood changed. I just didn't want to be there anymore. I said my goodbyes, found my bike, checked directions on my phone and left. It wasn't until I'd crossed an unfamiliar bridge that I realized I was going exactly the wrong way (of course) and was now in South Boston. Sigh. I got back on track and I was about halfway across the bridge I usually take to campus when I suddenly felt like I could breathe easier and thought 'it's good to be home.' The thought made me blink. Home? I've been here less than two weeks. And more interestingly, Cambridge is apparently home; not Boston.
What strange creatures we humans are.

Small town girl in a medium sized city
Fast forward. I accepted Boston University's offer and six months later I'm frantically packing up, finishing photo jobs, and compiling the last data and figures for one of my papers at the lab while hiring new staff, apartment hunting via email/craigslist, savoring my last Plum Street Porters, playing as much soccer as my body will tolerate and getting on a slack/high/longline as often as possible. After my last day at work, I rode with my Dad and his business partners to Colorado Springs. My sister and I spent a day with them at gluten free convention playing spokeswomen, handing out samples, and selling a truckload, literally, of their products. The next few days included lots of time with my niece and nephew, a very good bottle of wine with my sister, and my first professional massage (by the way, Mel, there's a Massage Envy right by my Trader Joe's!).
So, Boston. Other than once again losing my knife to airport security (I NEVER remember to pack it), my travels were rather uneventful. And I have since recouped my loss in duplicate.
My sanity balances on a slackline |
Other than the expense of meat and tomatoes (potatoes, fortunately aren't too obscene), Boston suits me. Hurricane (or tropical storm as she was later known) Irene was disappointing compared to a real Montana storm. Cambridge is a wonderfully quirky neighborhood. I live in apartment #5, but there is no 1, 3, or 4 and 2 is split into 2L and 2R. Google can't find my apartment. And I actually saw a bike with a frame made of bamboo today.
I've spotted quite a few potential longline parks and tons of places for teaching lines or tricklines, including the middle of Commonwealth Ave, just outside my work. The divider there is basically a long narrow park with a little path, benches, and plenty of useful trees. Also, I am now the proud owner of an ascender and a few steel carabiners, the first bits of my longline 'investment' to arrive.
Hmm. Speaking of porter (yes, I know it was a while back, but it stuck in my head) I've got one chilling in the freezer and I do believe it is dinner time. Then back to photo editing.
Cheers.
