When did we suspect that the Earth was round?

I recently read the passage:

“On the summit of the pillar, above one hundred and twenty feet from the ground, stood the colossal statue of Apollo. It was of bronze, had been transported either from Athens or from a town of Phrygia, and was supposed to be the work of Phidias. The artist had represented the god of day, or, as it was afterwards interpreted, the emperor Constantine himself, with a sceptre in his right hand, the globe of the world in his left, and a crown of rays glittering on his head.”

This caused me to pause and question my assumptions about how recently mankind had determined that the Earth was round.

I mentioned this to my mom. She immediately set me straight and sent me an essay by Isaac Asimov (earthpix). The essay is short, and well worth reading. As an extra incentive to read it …….. it explains how in 240 BC Eratosthenes used two sticks to correctly estimate the radius of the Earth.

Pylon appreciation

People are “into” lots of things, but lots of things people are “into” I had no idea were even things. I finally got around to reading a book I’ve had on my reading list for a long time: The Pleasures and Sorrows of Work by Alain de Botton. Chapter VII is on transmission engineering and introduces a founding member of the Pylon Appreciation Society (“Ian”). I didn’t even know what pylon was, so obviously I had no appreciation for what pylon-appreciators must be appreciating.

Pylons are those big metal things that hold our electricity cables. When you stand under them you can hear a crackling sound which is called “corona discharge” (the sound of nitrogen and oxygen splitting). The distance between pylons is a very interesting science: longer cables, vibrate more, the more they vibrate the weaker they become and the more pressure they put on the pylon. The reason we don’t see the cables shaking violently even with massive amounts of electricity vibrating through, is because of weighted tubes that have springs which vibrate at an opposing frequency to the conductor. So that’s what the coily things do that are attached to pylons.

Something I found particularly interesting was the naming scheme for cables that are different widths. Widths vary depending on how much electricity they need to carry, and this determines how many strands of aluminum cable are twisted together. The names for cables of different thicknesses are named after flowers that have stems with similar looking cross-sections. The smallest type of electric cable is called poppy because it has one strand of aluminum surrounded by six strands that go around the circumference. As you go up in size there is the laurel, the hyacinth, the marigold, the bluebonnet and the cowslip. 7,19,37,61,91,127.

The number pattern got me side-tracked because I couldn’t figure out how you would predict the next number in the sequence, de Botton didn’t seem to find this interesting because he didn’t mention anything about why cables and flowers should be like that.

The pattern is this: each number in the sequence is predicted by 1+6(1/2 n (n-1)). When you google this that means the numbers are called hex numbers or centered hexagonal numbers. You can also predict the next number in the sequence by taking the difference between consecutive cubes.

In our field we use hexagonal numbers to get the area estimates for ring vaccination. Maybe we should start calling our ring vaccinated areas after flower names. Large vaccine rings can be bluebonnets and we can call the smaller ones “Poppy vaccination campaigns”?

 

Harbinger of Spring

Someone had the lovely idea of planting daffodils on campus. Seeing them makes me happy and reminds me that days of sunshine will soon be here.

Daffodils

I wandered lonely as a cloud
That floats on high o’er vales and hills,
When all at once I saw a crowd,
A host, of golden daffodils;
Beside the lake, beneath the trees,
Fluttering and dancing in the breeze.

Continuous as the stars that shine
And twinkle on the milky way,
They stretched in never-ending line
Along the margin of a bay:
Ten thousand saw I at a glance,
Tossing their heads in sprightly dance.

The waves beside them danced; but they
Out-did the sparkling waves in glee:
A poet could not but be gay,
In such a jocund company:
I gazed–and gazed–but little thought
What wealth the show to me had brought:

For oft, when on my couch I lie
In vacant or in pensive mood,
They flash upon that inward eye
Which is the bliss of solitude;
And then my heart with pleasure fills,
And dances with the daffodils.

William Wordsworth

Androgynous names and the mind-altered present

Two things happened when I started grad school: one, I started drinking more coffee, and two, I started noticing how frequently my name gets misheard, mistaken or mispronounced. The two things are highly correlated: coffee shops are where my name is most often lost in translation. Spelled on my coffee cups have been names from Jill to Gel to Jeff to Josie, none of which I mind and all of which are close, or somewhat close to Jo.

This weekend for the third time, I got JF.

Most of the time people’s tendency to be bad with names gets blamed on memory, but when name mishaps only occur on first encounters (i.e. with unfamiliar people in coffee shops), it is hard to blame an unmemorable past. For a while, I blamed my diction. Maybe my “o” sounds like “f” or “l” or “s.” Maybe I am so in need of coffee during these times that my uncaffeinated grumblings sound like word slurrs. Maybe coffee shops are too loud to hear the distinction between “o”s and the 25 other letters of the alphabet. Maybe I have an accent that causes my words to sound full of consonants. So I told myself it was my fault, I needed to speak up, lean in, I tried spelling. And now instead of Joans and Jills, I get JF.

My new hypothesis is that it is not me as much as it is my name. If my name was Jill it would probably never get confused to Gel. Do Rachels ever get Richards? Does Karly ever get Carl? Probably not. The problem here is living androgynously in a gender schemata world. I am guessing that names that are androgynous but have a stronger association with one or the other gender are less expected when meeting a new person, and thus more frequently mistaken.

Though we don’t think of our minds as expecting a particular name when we first meet someone, we likely are. A study at Miami University explored why it is that certain people seem to “look” like or “fit” their names while others don’t and what facial features trigger certain name expectations. Gender is an obvious cue for most people to remember names, but less obvious features also play a role in setting up our expectations for what someone’s name should be. The study linked specific facial features to specific name associations: The name Bob is generally linked to a rounder and larger face, Tim is thinner. Perhaps it is when name and feature are incongruous that names on coffee cups go awry. A large faced Tim or a skinny Bob — would they get as high a frequency of mistakenly named cups as a girl named Jo?

If expectations for names alters our ability to hear a person’s name, where else are our mind’s expectant neurons veering us away from being more perceptive of our surroundings? We hear often that memory is unreliable, but it seems like our minds can be just as unreliable in the present when we let our expectations dominate.

The Pennsylvania Epidemic

My oldest nephew is seven. The last time I saw him, we spent hours and hours reading Harry Potter together. One of the things I love about this kid is his natural tendency to turn the ordinary into the wonderful and mysterious. For example, when he heard I was moving to Pennsylvania, he paused for a moment and then said,” Hmmmmm. I guess that’s like Transylvania except instead of teeth for fangs the vampires have pencils”. At first I just thought this was very clever and funny ……….. but lately I’ve been looking a little wan and my teeth have been hurting …….. and now I’m concerned that he had a much deeper appreciation of the risks involved in moving to Pennsylvania than I did.

Nothing kills inspiration like a blank page

It might be better to start out a blog post by deleting a block of random letter combinations from the screen, and then typing.

The blank page is a known killer of writing. This phenomenon even has a name: Blank Page Syndrome. With infinite choice of what to write, writing anything at all becomes impossible, or at least much harder.

How to beat it? Lifehack’s website offers 10 suggestions. My favorites of these include starting in the middle, setting small goals such as writing for a set number of minutes, free-writing just anything to get yourself started without regard to whether it is any good or complete garbage (editing is much easier), and changing your physical location.

Other ideas? Having some curly fries at the ‘skellar with lab mates is also inspiring.

Why don’t cats, dogs, and horses get malaria?

Lots of animals get malaria, including birds, reptiles, snakes, primates, bats, rodents, and at least one ungulate, the antelope. Even turtles get Haemoproteus parasites, a phylogenetic sister species to those in the Plasmodium malaria parasite group. So why don’t cats, dogs, and horses get malaria? There are also no documented cases in pigs that I could find, and with a questionable exception of a case in a water buffalo, bovids may also be exempt.

I started looking for similarities among animals that haven’t had malaria.

One of the most important organs for humans and rodents in fighting malaria parasite infection is the spleen. In a bold statement, one researcher suggests that the evolution of spleen structure may have been driven by malaria parasite infections. Primates and rodents have a defensive type spleen. Looking for differences among spleen morphologies seemed like a logical place to start.

I found that canids and equids have in common “storage type” spleens, called dynamic sequestering spleens where they store blood and have drastic changes in hematocrit with exercise. Cats also have this type of spleen that works as a dynamic sequestering organ for blood. How much blood is being stored? Horses store up to half of their RBCs in the spleen, and dogs store 1/3, changing hematocrit drastically when going from resting to exercise. Cats may store 20% of their RBCs in their spleen. In contrast, our hematocrits change maybe 5% with exercise, and no more than 2-3% of this change is due to the spleen, the rest is from water moving to our muscles.

So, is it a coincidence that animals that have dynamic sequestering spleen are malaria-free? Correlation isn’t causation, and since horses, dogs, and cats share a closer phylogenetic history than the rest, it is difficult to sort out whether lack of malaria parasite infection is because of spleen morphology or other shared features.

The spleen isn’t a commonly discussed organ (there’s even a paper called “The avian spleen, a neglected organ” by J.L. John in 1994, which states that bird spleens don’t store red blood cells). However, the spleen removes parasitized red blood cells, is involved in making new RBCs, has immune functions, and plays a large role in malaria clearance. So, is it spleen evolution or morphology the reason horses, cats, and dogs don’t get malaria? And could it be that rapidly shifting hematocrits stop these parasites?

Some thoughts about blood

This image was lifted from the Radiolab page without permission. For other cool art by Jonathon Rosen check out http://jrosen.org/index.html

I’ve been thinking about blood lately. I’m not the only one interested in the stuff. There was a great Radiolab podcast about blood not too long ago that covers the human obsession with blood. Recently I’ve been a little obsessed with the question of why blood is so bubbly. Are our veins filled with soap? (Don’t worry, I’m joking).

I’ve worked with donated human blood to make aliquots for feeding to bedbugs, mosquitoes, and for the malaria culture. In doing so, I’ve noticed blood forms pretty stable bubbles very easily in at least two instances. The first is when it is mixed with air, such as in a pipette when trying to get the last bit of blood from the bottom of a vial, and the second is when mixed with water, observed when washing up. Why?

My first thought is that maybe it is because of the anticoagulant (CPDA-1) used in the blood bag for collection, but I couldn’t pick out any ingredients in that were a red flag for a bubbly reaction with air or water. Blood is really viscous, which might explain bubbles forming readily in a pipette, but not in water.

Sigma-Aldrich’s website on properties of blood was helpful and maybe a step forward to solving the mystery of the bubbles. Blood contains 0.9% inorganic salts, including sodium, potassium, and carbonate. I’m no biochemist but sodium carbonate and potassium carbonate can both be used to make soaps so maybe my joke that we have soap in our blood isn’t so far off the mark? I’d love to know.

Biomimetics

A large part of my choice to specialise in disease evolutionary biology was (and is) a belief that it’s the most interesting part of biology. In turn most of my decision to become a biologist rather than another flavour of nerdy scientist was that I thought other forms of science were boring in comparison (and almost certainly harder). However, I do count myself very lucky to have friends who are equally convinced that their area of specialisation is the most interesting thing in the world and who are willing to patiently explain some interesting titbits in their attempt to convince me. I especially appreciate this when we are on runs as not only does it feel like I am expanding my mind while getting fit but it also has the great side benefit that if I time my dumb questions right I can get out of doing any of the talking on the uphill’s.

Something I learnt about recently while running with my friend Jay is biomimetics in the design of airplane wings.  The fact that basic airplane design started with observing bird morphology is not surprising, what impressed me more is that NASA is still studying bird adaptations in order to further improve design and therefore fuel efficiency. Large birds such as eagles, hawks etc. have feathers at the tips of their wings which can curve up eliminating the vertical vortex created around the wing and reducing drag. Recently airplane designers have started using similar winglets with the same effect of reducing drag. This means fuel consumption is reduced and also that planes can have smaller wings while still generating the same vertical lift.  There are also many other examples of where biology is being studied to help in aeronautical engineering. For example, North African desert scorpions have patterned exoskeletons with groves that help them withstand sandstorms so forceful they would strip paint off steel. Small grooves and bumps on the scorpions amour distribute airflow and reduce abrasion, something that again can be copied in the design of plane surfaces. I would like to say that I impart as much fascinating biology to my running partners but sadly I am normally too busy trying to breath.

birds and plans

Part 1 of 2

I should start by saying that I don’t really believe in reincarnation.

(Well, I should probably start by apologizing to Andrew, who probably was expecting other kinds of topics on the blog. Don’t worry- part 2 will be more related to science.)

I think that I first heard about reincarnation at a pretty young age, when my grandmother mentioned that she felt like she had done such-and-such in her past life. I was probably freaked out by this possibility then. Souls, spirits, ghosts, magic, and aliens were basically equivalent and equivalently confusing to me as a child and, while my default stance towards natural things was to be curious, my default when it came to supernatural things was to be afraid. This fear of the supernatural I blame on the neighbors who tried to save me by taking me to church, without having had anyone explain to me that there is some debate about whether or not Hell is actually a place.

I spent a lot of time being afraid as a kid because people didn’t sufficiently explain things to me. In the absence of explanations, I wasn’t always even able to characterize things correctly as natural vs. supernatural. When I realized this later, I used to think about whether rain would have terrified me if I grew up in, say, the Atacama, and then moved somewhere else. (Most likely yes.)

Also later, once I figured out that eclipses had nothing to do with aliens and I wouldn’t go to Hell for wondering if aliens existed, I also got to thinking about reincarnation. And I came to the conclusion that, if it did exist, then I must be a newbie. Reincarnation is where, I reasoned, people’s intuition came from: you learned these things in your previous life. Since I usually feel like I don’t know anything and that the thing that I use to make decisions besides logic (which is what I would describe as intuition) is so often wrong, this must be my first time around the block.

Moving by the numbers

Since I spent four days of this week on the road, rather than in the lab, I thought I’d share some data I collected along the way.

We traveled for roughly 2,050 miles. The first hypothesis we tested was that cats that have never ridden in the car before will adjust. Our cat took about 4 hours to resign himself to the fate of being trapped in a car, followed by a one hour adjustment period at the beginning of each new day on the road (this means approximately 7 of 34 hours, or 20% of the trip was accompanied by a soundtrack of meowing. The ratio could have been much worse).

Stars of roadside attractions are often larger than life. There was the world’s largest prairie dog, a cow with an extra leg, (we didn’t stop for these), and what was probably one of the largest crosses in the country which dwarfed the trees and made quite the impression even at 80mph.

The largest wind chimes are 49 feet tall and exist in Kansas. This prompted us to test a second hypothesis: that it is windy enough in Kansas that having two bikes strapped to the back of a Civic decreases fuel efficiency by about 10 mpg. Our alternative hypothesis was that the air pressure in the tires had fallen, which we ruled out at the next gas stop (a pressure gage is $1.69 in Nowhere, KS). The fact that our mpg went back to normal after Missouri where there were some hills to break up the wind supported hypothesis #1.

Average gas prices ranged from $3.19 to $3.69 per gallon along route 70. On a side note, I feel this must have been too cheap because there were certainly a lot of cars on the road that had only one occupant, and rarely did we see buses. There was one cyclist chugging along in eastern Colorado with some huge saddlebags, and three hitchhikers along the highway, but I’m not sure we can assume these alternative modes of transportation were due to the price of gas. We kept track of license plates we saw from other states while on the road, documenting 41/50 states. The majority of those missed were from New England, which could be expected since we were heading East and only went as far as the middle of PA. It’s good to be back.

Thinking of a career switch?

I was just reading the online newspaper and I was stunned by the announcement that the selection for a commercial trip to Mars, scheduled for 2023, has opened. Mind you, this is a one way trip, the plan is to establish a human colony and grow this population by four every two years.

Crazy? Get this, cause who do you think is all going to pay for this? Us, sensation-seeking human beings. That´s when I realized this was clearly a Dutch initiative. Remember ´Big Brother´? Big business. Combine that with the dollar making versions of ´Pop Idol´ and a very simple commercial idea was born: Let the selection of astronauts be a publicly broadcasted sensation, one where, of course, the viewers can cast their votes. The selected candidates will be followed in all the ups and downs during preparation, travel to and life on Mars. This is all planned to become the biggest media-event in history.

My disbelief just grew and grew. Is this some kind of April fools joke? Or am I just too naïve to think this would still be too much science fiction? Also, who would ever want to sign up for something so permanent as this? Perhaps expectedly, the latter doesn´t seem to be an issue, the organization received tens of thousands applications before the call was even opened. There is clearly lots of ambition out there to be the next Neil Armstrong.

What do you think? Is this crazy? Exciting? And most important of all: will you watch?

It’s a dangerous place

The recent warm weather has been a delight after what seems far too long a winter. Going for a run now is not the brass monkey exercise it has been for the last few months and jogging between the trees on a sun-dappled path is a pleasure(1). But the woods hide a number of dark secrets. As Peter’s grandfather said so portentously, “Its a dangerous place. If a wolf should come out of the forest, then what would you do?”

Well, maybe not a wolf round here but there is an equally, nay more, dangerous creature that goes through a strange transformation in a few weeks time.

I encountered it for the first time last year and still don’t feel I have fully recovered. There I was, sometime in May or June, running along, few cares in the world, a latter-day Fotherington-Thomas(2), when there was a rustling in the undergrowth and a rufous bundle exploded onto the path and began to bear down on me with murderous intent.

Yes, there. That animal. See? Vicious little bastard. Mean glint in its eye. What? What do you mean “where?” No, its not behind the ruffed grouse, it is the ruffed grouse. Huge sharp …

Okay, they might not be large but size, as we all should know, isn’t everything. After all, when on the rampage they ruff their neck feathers like Nedry’s nemesis, point their wings like the pectorals on a great white shark making its very final approach while at the same time they utter blood-curdling clucks. True, their excuse may be that they were only protecting their newly precocious offspring – “well honestly officer, look at him, all that heavy breathing and dayglo spandex. Wouldn’t you have feared for your children?” – but they are wholly undeterred by any difference in size between them and the object of their fury. They savage ankles without fear or discrimination.

All in all a terrifying experience, enough to make anyone soil their armour. The only thing one can do, in the absence of the Holy Hand Grenade of Antioch, is, of course, run away. Or if cornered, fend them off with a suitable twig.

Thankfully the rabid grouse season is relatively short lived (coincident with the fledging of offspring) and the chance of encountering ones imminent demise passes by the end of June. Then we can run unmolested again and go back to monitoring whether the chipmunks are stockpiling ordnance for a summer offensive.

But that, as they say, is another story.

1. That may be a gross exaggeration if not a downright lie considering that, aside from the ever present nag of age, the sore achilles, the recalcitrant knees, and the slight lisp the only real pleasure comes when it ends.
2. “He sa, Hello Flowers! Hello Trees! he is uterly wet & a wede.”

Musings: Hemingway and Evolutionary Neuroscience

I am an “Analytical” on the common “social styles” quadrant used to assess communication styles in the workplace. I doubt this surprises anyone who has spent more than five minutes with me, and my analytic personality even invades my procrastination time. While on reddit the other day (the greatest time sink in the history of the internet), I came across two things:

1. “Happiness in intelligent people is the rarest thing I know.” -Ernest Hemingway
2. This article.

Both of which I mulled over for a while, and then synthesized them.

1. I think Hemingway is brilliant, but he is clearly speaking from a biased stance of self-reflection, and most likely said this while drunk. However, his sentiment stuck in my mind, as I clearly surround myself with highly intelligent, yet [seemingly] happy people on a daily basis. But then I thought about figures I consider to be highly intelligent, mostly of the artistic variety, who are/were also plagued by at least one of the psychiatric symptoms mentioned in (2.) – anxiety, paranoia, obsession and compulsion. What gives; is there a correlation?

2. If you read the actual paper, you’ll see that the entirety of this study is based on the platform of the Evolutionary Threat Assessment System Theory, a portion of neuropsychology that suggests that parts of the brain (basal ganglia, prefrontal cortex and the limbic system, a set of structures responsible for emotion and memory, primarily) have evolved to detect threats, tangible or intangible. Malfunctions or deformities in this anatomy is suggested to contribute to a spectrum of mental illnesses, but I’ll be focusing on anxiety (as overanalysis often leads down this road). But I wasn’t interested in the ETAST in the context of religion and spirituality; I was concerned with it in the context of intelligence (I know this is a subjective term, but bear with me, this isn’t my forte).

Human intelligence and our understanding of our surroundings and the world in which we live is continuing to evolve. We’re slowly moving away from performing rituals to appease an angry deity, but we aren’t seeing a reduction in generalized anxiety disorders (GAD) in adult populations. This, in some percentage of diagnoses, is surely due to overdiagnosis as well as changes in mental health evaluation. However, I posed that along with high intelligence comes a certain degree of perfectionism and dissatisfaction (perceived threats), which, in some cases may lead to anxiety (an evolved defense mechanism), and in diagnosed GAD patients, to a level of chronic anxiety that is surely maladaptive.

I did find some support for my thoughts throughout my hour of searching (and making a facebook plea to my social scientist friends to help me out). A study published last year demonstrates that in patients diagnosed with GAD, scores on the Wechsler scale of intelligence and IQ tests positively correlate with scores of a “Psychosocial Work Environment and Stress Questionnaire”. Now, to me, these data present issues as they are from a small data set (GAD n=26, healthy n=18) and the tests are obviously quite subjective. However, the study cites several findings supporting that choline levels in the brain can be correlated with neuronal processing integrity, which is positively linked to intelligence. Choline metabolite levels (obtained by specific MRI scan sequences) in GAD patients showed the same positive correlation between IQ and “worry score” as noted by the PWSQ.

Although being a chronic worrier doesn’t necessarily mean one cannot be happy, I think that perhaps both Dr. Coplan of the SUNY Medical Center and Mr. Hemingway are on to something. As someone who has a decent level of intelligence, and one who over-analyzes and frets about nearly everything, I can attest that I am one data point that would support the above hypothesis.

Happy National High Five Day!

Yes, it really is National High Five day (the third Thursday in April), and I am personally a huge fan of the high five.  For those of you that are too old to appreciate the high five (e.g. Andrew and Matt), the high five is a hand gesture that occurs when two people simultaneously raise one hand about head-level high, and proceed to slap the flats of their palms together against each other.  Sometimes this gesture is proceeded by one person verbally saying “Give me five” or “High five,” but if you happen to be someone that doesn’t recognize when a high five is being invited without the verbal cue you automatically fall into the old person category.  The reason why I love the high five is because it typically represents two people acknowledging an accomplishment spanning from just being friends to actually getting something meaningful done together. 

Here is some history of how the high five got started and its many meanings.  The high five most likely originated as a variant of the “low “ five, which was already prevalent in African American culture since at least World War II, and was given as a greeting between friends.  The first documented case of the “high” five occurred on October 2, 1977 between two baseball players, Dusty Baker and Glenn Burke, on the Los Angeles Dodgers.  Dusty Baker had just hit his 30th homerun during a game against the Astros, which made the Dodgers the first team in history to have four players each with at least 30 homeruns.  So, the players were pretty excited.  Burke, who was waiting on deck, threw his hand up in the air in a major show of enthusiasm to greet his friend as he crossed the plate.  Baker, in response, slapped his hand and the “high” five was officially born.  The Dodgers then went onto popularize this gesture throughout the remaining season, and the high five became a universal gesture of celebration between teammates in the sports arena.  Burke, who was one of the first athletes to be openly gay, went on to use the high five with other homosexual residents of San Francisco after he retired from baseball making it also a symbol of gay pride and identification.  In the nineties there was a falling out of the high five, with many youngsters being too cool for school thinking that the high five was cheesy.  Maybe the Grunge era was when the fist pump got started?

Once the high five originated, there quickly were many variants of the high five radiating out from the site of origin.  If one denies someone a high five, this could be interpreted as the person being too old (e.g. Andrew and Matt), as an insult, or a jest.  There is also the self-high five, which honestly is a bit sad, and our favorite rhyme growing up: “Up high, to the side, down low, your too slow.”  This involved the initiator of the high five to withdraw their hand on the low part of the sequence before their partner has a chance to slap their hand.  And probably my most favorite and most recent addition of the high five is the “air five” or “wi-five,” where two people high five from a distance and never physically touch.

Even though the high five has worn many hats spanning many themes including race, sexual orientation, and athletics, in general it has always represented a symbol of comradery.  So I am a fan, and Happy National High Five Day.  Wi-five to you all.

Pray for rain

Get psyched, because tarping season is here!  With a 30-foot tarp and four tent spikes in my car, all that’s left is to find a hill and wait for a storm.

Some of you might be unfamiliar with the sport of tarping.  I feel sorry for you.  Or maybe I envy you.  I feel sorry for you because you have never experienced the most enjoyable sport ever created, but I envy you because you are still able to experience tarping for the first time.

Tarping is a sport that was invented by a team of astronomers, physicists, and biologists in Madison, WI during the summer of 2004.  The sport of tarping is comprised of a series of slides in which the participant (slider) travels down a tarp-covered hill.  The goal is for the slider to achieve a higher tarping score than his or her opponents.  Scores range from 0 to 6, with a 6 representing a perfect slide.  These scores are tabulated from 3 equally weighted categories: difficulty, style, and distance (measured on a log scale).  The only rule in tarping is a “no blatant cheating” rule.  Violation of this rule results in the disqualification of that slide’s score (or the previous/next slide if the cheater was not the slider).  There is no longer-term penalty.  Refereeing and judging are performed subjectively by anyone other than the slider (but see no blatant cheating rule).

The regulation tarping field is comprised of 1) a grass-covered hill, 2) a tarp spiked into the ground, and 3) fresh rainwater.  Even with these regulations, every tarping field is unique because of variation in hills, tarps, and rain intensity.  This feature keeps the tarping experience novel, and often results in a “home hill advantage.”

And as a final tip, it gets pretty muddy out there.  Wear old clothes.

 

The Complete Works of Christopher Curtis

One question that I sometimes interject into awkward silences as an emergency conversation starter is “what superpower would you wield if you could pick any superpower?”

Should we find wordlessness filling the space between us, I should warn you now that this is kind of a trick question: I will judge you if you pick flight. Lame. That answer totally lacks imagination. Clearly, if they were handing out superpowers, any Tom, Dick, or Stanley in front of you in line is going to take flight, and you’ll be left scratching your temple, earthbound, while the distributor calls “Next!” I’m sorry to be a snob about this, but…come on. You are a biologist and know about all sorts of awesome “superpowers” that other species have; think outside the box!

Anyway. My top two choices have in the past been “not having to breathe” and “the ability to communicate in any language.” Not having to breathe could be useful in all sorts of situations- running and free-diving, for example. I’d also probably live a pretty long time, if sharks or whatnot during the free-diving didn’t kill me, assuming that my cells had some other awesome way of getting oxygen. Being able to communicate in any language would also be very, very awesome. I am tempted by this possibility (haha) especially because people consider “music” and “R” to be languages, so I could be a rockstar in any sense I chose.

Lately, as I’ve been reading things and writing up, I have been thinking of a similar, scientist-specific, conversation starter: “If you could pick one scientist whose entire body of work you would have instant (superpower-like) recall of, who would it be?” I’m currently leaning toward Chris Curtis, because I’m pretty sure that he already thought basically every mosquito-control-y thought I ever had, and so I feel like I’d be better able to move into some novel brainspace, knowing for sure that my question had already been answered.

Bilingual parrots

Taco the African gray

Having a parrot is kind of like having a small alien equipped with a copy of Lonely Planet’s the Human Home. Parrots hatch from eggs, females are the heterogametic sex, their red blood cells have nuclei and yet, by flipping to the vocabulary section of their guide book, they still have the ability to ask where the bathroom is.

Like the aliens on movies and TV shows, the ability to communicate makes parrots unusually relatable to humans, despite our obvious physical differences. Not only do parrots communicate with us in our own language, they communicate with each other in ways that are almost impossible not to anthropomorphize.

For example, parrots have contact calls they use to keep in touch with their companions. In Costa Rica, yellow-naped Amazon parrots that roost in different geographic regions have their own dialect of calls, despite extensive gene flow between the different regions (Wright et al 2005). Parrots that roost at the intersection of regions can use both dialects interchangeably, although I’m not sure if this is equivalent to switching from “y’all” to “yous” or from “hello” to “bonjour.”

Furthermore, the contact calls of parrots are different than the calls made by most other animals because they are specific to an individual and other individuals can use the signature call to address that individual. In other words, parrots don’t just say “attention all parrots, I am Parrot,” they say “attention Specific Parrot, I am Other Specific Parrot.” Like our given names, these unique contact calls are learned by baby parrots while in the nest and they depend on the vocalization of mom and dad (Berg et al 2011).

All of this is to say that when it comes to late night laboratory companions, I do believe that the top choice is clear.

I know what you mean

Words are very important to me. For example, one of the main things that worries me about going to a cool place in Asia is that there might not even be letters that I recognize on signs. I imagine it being like having one of my senses taken away: I need my sense of reading!

For another example, I have trouble remembering a person’s name unless I know how they spell it. This could be a consequence of having a name that is inevitably misspelled, but I really think it’s because my brain finds it difficult to hold on to something unless it’s been condensed into the form of a series of letters. It’s kind of an “if a tree falls in the forest…” type of issue. That is, “if a thing without a name falls in the thing without a name…” You see my problem? (Perhaps you see more than one, ha ha.)

Together, these examples provide a metaexample of why I love to read: I love to understand. I love when words are aligned in just the right series to suddenly bring an idea into sharp focus. “Aha!” moments, if you will. They feel so good on your brain, and tend to be great things to revive lagging conversations.

I must admit, though, that my favorite thing to read- and to write- is a phrase or sentence that conveys a thought or feeling you’ve had in exactly the way that you mean it, so that you pause, and re-read it, and say, “yeah.”

Here’s the passage that caught me in The Subtle Knife, by Philip Pullman, and made me think about this…

“And each of them saw their own expression on the other’s face. Will remembered that moment for a long time afterward.”

A short review

In my role as bridge vector between our research group and the seamier side of OPP and EHS I have, while trying to maintain up to date knowledge viz a viz health and safety, taken any number of courses and read all sorts of pamphlets appertaining to life in the laboratory. Recently one such document caught my attention. Put together by a special EHS sub-division (Services for Health, Environment, Employee Trauma and Ennui) the authors had looked into and subsequently produced a report on “Alternative Late Night Laboratory Companions: A Guide to Non-Humans.”

Being familiar with the echo of empty laboratory corridors I have often felt, as I am sure you have, that in the absence of a colleague a bit of alternative, but still real-life conversation would be more desirable than having to load yet another Barbara Cartland onto the ipod. A whole report assessing the conversational abilities and other merits of non-human animals as late working companions was definitely something to peruse and report on to the group. So I dipped into the weighty volume and came upon the section headed “Domestic Fowl,” which started enthusiastically by stating:

Everyone loves chickens. Be they Light Sussex, Rhode Island Red, Longhorn Leghorn or, praise be, a Buff Orpington Cock. Conversation is never dull in the lab when there is a chicken around. They have that knack for small talk that makes a long day at the microscope fly. Even if they can’t.

Despite this high praise the section goes on to conclude:

“However, chickens cannot be recommended as companion animals in the laboratory. Though their conversational qualities are well documented they are wont to preen.”

In the same section ducks get short shrift as they are “inclined to waddle” a distracting behaviour the author notes, “which can be much better observed at Walmart.” Geese receive the most scathing assessment:

“Geese have no saving graces in the lab. They are haughty and inclined to a variety of neuroses which, over the course of an evening spent sorting pupae can be overwhelming. What is more they regularly sod off somewhere north. You might be on your eighty-first dissection and in dire need of a good chinwag, when there is a sudden flapping of wings, your notes get buffeted into the chloroform jar and all your carefully prepared samples end up in the fag ash on the floor. The geese meanwhile depart for Svalbard and a summer of sex and sunshine.”

Mammals barely figure in the report with cats being described as only wanting to talk about foreign policy,” horses “lugubrious in the extreme” and porcupines “prone to emotional outbursts.” I feared dogs might be discussed but thankfully all they authors say is; “Dogs cannot be seriously considered as companion animals as they have no conversational ability whatsoever.

As if the latter really needed pointing out. Finally I found the important section:

One might consider fish,” the document stated. Yes, I do. Often, I thought. “The particular choice of laboratory companion fish is a difficult one. Some swear by carp. They are intelligent, thoughtful and ruminative conversationalists. However, the pace of their discourse is not to everyone’s taste. For those inclined to snappier repartee the experts suggest one of the cleaner wrasse. Naturally cleaners, given their original job, have the full hairdresser type repertoire complete with a range of put-you-at-ease entrees, a lightening quick ability to change topics when the previous one flags, a surprisingly thick skin for those awkward moments and the ability to make a really good cup of tea.

Excellent, we should get one for the insectary I thought. But then I noticed an addendum:

Beware however, the Fang-toothed blenny, the cowboy of laboratory conversationalists. They may look like wrasse and even act like wrasse but once let in the door turn out to be surly, uncommunicative and if pressed, prone to violence. While this may increase the excitement, losing your focusing finger will not facilitate the oocyst counts.”

There was much more but in the end I had to settle for the disappointing fact that, what with the variety of options available and the lack of any clear choice, the lab would have to continue to echo with the earnest tones of NPR’s “This American Loofah.”
