Deep thoughts with Dave Kennedy

-The person who invented the saying “When the #%@$ hits the fan” either had a vivid imagination or a very dirty living room.

-Six percent of people who have ever been born are still alive, meaning that only about 100 billion people have ever died.  After accounting for reincarnations, heathens, and murderers, there is no way that heaven is overcrowded.

-People who deal in absolutes are always wrong.

-The guy who copyrighted the Happy Birthday song should hurry up and patent the placebo effect before someone else does.

-Luck is just skill leaving the body.

-Last night I dreamt that my shoe lace broke.  This morning I was relieved that I can’t dream the future.

-What would a mirror see if it reflected inward?

Human uniqueness? (includes a brief spoiler for the movie “Lucy”)

I recently watched “Lucy”, which can only be labeled as the most scientifically incorrect movie perhaps of all time. It takes as its premise the incorrect fact that humans only use 10% of their brain’s “capacity” and then proceeds to show us the absolutely mind-boggling progression of a woman’s abilities as she ultimately uses 100% of her brain to travel through time in an office chair to deliver the secrets of the universe to Morgan Freeman, all of which conveniently fit on a USB drive.

I left the theater with a fellow grad student, our brains throbbing from disbelief at how events had proceeded. It was an engrossing, utterly disturbing experience that left us shell shocked. I stand behind my statement that “It wasn’t completely bad per se, but it was completely wrong”. Interestingly enough, however, it sparked a conversation based on the following question: how different are humans from other organisms on Earth?

As common and seemingly simple as this question is, I find myself visiting it frequently. I oftentimes think that as biologists we have a tendency to have a perspective that is unique from that of traditional philosophers or social scientists. We publish accounts of animal behavior that resemble are own human perceived idiosyncrasies, in order to squander arguments that these aspects are part of what make us unique organisms. We seek alternative explanations for patterns in human conflict or the establishment of empires, paying attention to environmental factors that may have played a role, in addition to social explanations.

Rather than finding these examples as damaging to the image of what makes us unique as human beings, I instead find them very comforting. What I find uncomfortable is the fact that people seem to consider Homo sapiens as operating outside the realm of natural laws that dictate the existence of every other organism. I’m not naïve enough to overlook the fact that we certainly are highly divergent in a lot of aspects and have relieved ourselves from multiple selection pressures (at least for the time being) and of course there are examples of other animals that self-medicate, use tools and make war, but we operate at the extreme level in all of these cases (to some degree); however, the tendency for people to be anthropocentric and forget the crucial fact that at some level we still are subject to the same natural laws that all of life is, might be one of the most depressing, annoying things about being human, ultimately contributing to the ambivalence with which we treat the planet and its inhabitants.

I think I only believe this 30% of the time, but soul-sucking Lucy brought out the thoughts.

 

So …….. what exactly does that mean?

 

I was recently told that to see stars that are farther away you need a longer telescope. I am taking this little tidbit slightly out of context ………. but …….. it is a perfect example of a statement that serves to bamboozle you. It seems to me that I could construct a telescope that was a mile long and I would be just as blind to the wonders of the sky as before I built it. If I want to see objects that are farther away, some things that might be useful to do are* (i) collect more light (maybe by observing over a longer period of time) or (ii) magnify the image of interest. In a telescope that uses lenses for magnification it seems probable that more magnification requires more lenses (perhaps separated by longer distances) and that this would result in a longer telescope. The statement “to see objects that are farther away you need a longer telescope” isn’t just opaque, it is dangerous. These types of statements are often said with great confidence and young (as well as old!) inquiring minds are usually discouraged from questioning further. A more informative statement might go something like: “One strategy to see objects that are far away is to magnify them, this can be done by using a sequence of lenses separated by carefully caculated distances. This is why the telescope in front of you is so damn long”.

*Disclaimer: I haven’t actually checked if these hypotheses are correct, so use at your own peril.

Translating ‘competitive release’ with help from a tree

I just arrived back east and decided to detour through the American Museum of Natural History on my way through New York. I’m chatting with my sister, the artsy, business-y member of my family who’s spending her summer living on the upper west side, taking courses at an art institute here. We speak different languages when it comes to our work and both have trouble understanding how the other one gets paid to do what she does. We are walking down the hall of North American Forests and are staring at tree rings on the Mark Twain tree, a 1,400 year old giant sequoia that took four days to cut a cross section, and weighs something like the amount of multiple tow trucks.

Across from the Mark Twain tree I get excited to see a smaller, but still impressive tree core which helps us in our struggle at crossing the science-art world boundaries.I point at the tree and look at my sister: “This is what I study!”photo

The tree rings of the loblolly pine show the effect of competition on the tree’s growth. When resources are limited and the loblolly was competing for water, sunlight and nutrients with its fellow plant compatriots the tree’s growth was inhibited. Without competitors, the tree’s access to resources become abundant, releasing it from the suppressive pressure of competition. Wiide fat rings mark the moment of competitive release.

My sister looks at me with an expression of an “Aha,” moment, “so this is what you do.” Then she says “That’s beautiful.” And coming from someone in the art world, I feel like I just received a very great compliment.

I’m amazed by the number of things that inspire me to think about work even when I’m in places I wouldn’t expect. Reminders of broad-scale ecological patterns crop of everywhere I start looking and it’s exciting to see reminders of our science’s remarkable applications when I have the time to cross its borders.

A (wo)Man of Science

When people ask what you do, how do you respond? Biologist? Researcher? Scientist?

I recently learned that if we’d been around in 19th century Great Britain, a common response would be Man of Science. As it turns out, the title of “scientist” is actually a relatively recent word, coined as the counterpart to “artist”. It is also a title that was not easily nor rapidly accepted in Great Britain. Americans, on the other hand, took up the term relatively rapidly and with much less debate, which served as further ammunition for the British anti-“scientist” crowd.

Read more about the history of “scientist” from science historian Dr. Melinda Baldwin.

Today, I’m not worrying about my gender.

No one can deny the facts – gender inequality is a problem in science. The average male scientist is paid more than his female colleagues, in academia and industry. Even when the underrepresentation of women in the highest paid positions of academia is controlled for, women’s wages are still not equal to men’s. Then there’s the ‘leaky pipeline’ whereby, despite taking PhDs in equal numbers to men, women leave academia more often at each of the next stages. So the number of women drops the higher you look up the academic ladder. The ‘leakiness’ of the pipeline is due to many factors, including the dominance of men on selection committees and the fact that women are more likely than men to leave science after having children. Women are also notably underrepresented at conferences, where they give less invited talks than men, perhaps because they turn down invitations more often than their male counterparts. I could go on (and will direct you to Megan’s blog below for yet another startling fact) but I’ve made my point. Inequality between men and women in science exists, it has many drivers and it is angering and alarming, particularly to a young female scientist like me.

Why then, when a female scientist comes to visit and the conversation turns to ‘being a woman in science’, do I feel frustrated and wish we’d just get on with talking about science? Why, when ‘women in science’ was posited as a subject for discussion at a meeting, did a fellow grad student send me an email containing one of my favorite sentences of all time – ‘I am so f***ing bored of hearing about how my vagina is going to stop me from being a scientist’. Is it because we don’t care? I totally refute that. Perhaps I am in denial? My awareness of the above shows that this isn’t the case. Rather, I think it is because the data do not mirror my experience. I live a charmed life as a female scientist, one in which my sex doesn’t matter.

On the surface, my situation looks pretty traditional. A young woman in a lab lead by two men over forty (sorry guys), at a center lead by a man, in an institute lead by a man. Scratch the surface, though, and it starts to look different. During my tenancy in the Read/Thomas lab, I have seen four graduate students defend their PhDs. All were women. Ten postdocs have been hired, of which just two have been men. Five babies have been born to four female postdocs. Most of these new mothers wished to return to science and have done so. They have gone on to publish papers, achieve illustrious fellowships and, in one case, bag a faculty job. Indeed, I do not see the pipe leaking (at least, yet). Of the three postdocs that have won faculty jobs, all have been women. Their jobs are at leading research universities. As it stands, the Read/Thomas lab has seventeen PhD students and postdocs, 76% of which are women. One learns one’s values from one’s experiences. The Read/Thomas lab is a pretty feminist experience – gender doesn’t matter, only ‘papers, papers, papers’.

Some would say that we’ve gone too far in the other direction and that a lab dominated by women is not good for gender equality. I agree, though I believe we were all hired on our merits and would feel queasy about quotas. I do wonder whether we might benefit from more men and, as someone who has always enjoyed male company, would quite enjoy having more men around. An ex-PhD student of Andrew’s (who returned to science on a grant specifically for women, after a stint as editor of a leading journal) also got me thinking about whether women can sometimes be bad for each other. Women are more likely to suffer from ‘impostor syndrome’ and, at least according to stereotype, to speak to each other about it.  I do think that my fellow female scientists and I sometimes reinforce each other’s doubts about our abilities. One of us talks about not feeling great and we sympathize, because we feel the same. Over time, it becomes ‘normal’ not to feel confident, when in fact we should feel bloody good about ourselves! After all, we’re at a great place, working hard to do high-quality science. A preponderance of women might also be bad for diversity. It is easy to imagine a positive feedback loop whereby the sex bias deters men from joining us, so that the proportion of women only rises. In the midst of recruiting the next cohort of budding PhDs with the (all female) CGSA board, I’ve often contemplated this. Not seeing themselves represented, perhaps men don’t feel welcome?

Our lab’s skewed sex ratio might provoke an alternative reaction – causing some to snigger that Andrew and Matt ‘like women too much’ (wink wink, nudge nudge). If it weren’t for the fact that so many women experience unwanted sexual attention so often, I would find such a suggestion laughable. I can say in no uncertain terms that I have never felt that they intend to do anything other than turn me into a functioning scientist and I do not know anyone who has felt otherwise. Moreover, were I ever to feel threatened by someone at work, I know exactly who I would turn to and don’t doubt that I would be believed.

In life beyond the lab, things appear to be looking up for women too. I confess to being on Twitter and to liking it. I follow numerous scientists, many of whom happen to be women. They are a diverse group and lead successful scientific careers. Indeed, one of the women I most admire – and whose profile picture features herself and her daughter – recently got tenure, to the congratulations of The Twitterati. These women are at the forefront of both science and the campaign for gender equality in science, often raising awareness of the latter by tweeting and blogging. They keep me aware of gender issues, too often horrifying me in the process. The positive thing, the irony even, is that I’m not learning about these problems from whisperings in the corridor or meetings in darkened basements. I’m learning about gender inequality in a public forum from women who have achieved success and whom I follow primarily because I think their science is cool. Indeed, their example has given me the confidence to write about this without fear of losing a job over it.

The fight for gender equality is far from over. I can think of many things about the attitudes of both institutions and individuals that make me feel uneasy as a woman. I would hope (perhaps naively) that if and when I have a child, things will have changed so that I get a reasonable amount of time off. Having the freedom to choose how to split said time with my partner, with no one pre-prescribing my role by giving me more time than him, would also be a major step forward. I’m sure that if I were a member of the LGBT community, my life would be considerably harder. I’m sure there are some old fogeys out there who will scoff at these ideas.  But I just want to say – and I hope not to have to retract this in the future – at this moment in my life, in this lab, I don’t think the fact that I have a vagina is going to stop me from being a successful scientist.

Give the guy a break

For those of you who don’t know, LeBron James is a basketball player — the best basketball player in the world, and he has been for a while now.  He was drafted straight out of high school at the age of 18, and everyone knew he was going to be great.  But throughout his career he’s been criticized mercilessly for being overrated, for being spoiled, for being a sell out, for abandoning his team, for being afraid of competition, for being a sore loser, for being arrogant, for biting his nails, for flopping, etc..  In a world where, allegedly, football players stab people, torture dogs, and rape girls, baseball players kill people, beat their wives, and steal cars, and basketball players get in fights with fans during games, deal cocaine, and point guns at teammates, Lebron James is vehemently criticized for the way that he announced his plan to change teams.  It’s probably also worth mentioning that the way he made his announcement raised over $3 million, all of which was donated to charity.

Now don’t get me wrong, I’m not a huge fan of the guy — when his team lost to my Orlando Magic in the playoffs a few years ago, he didn’t congratulate them on the win — but let’s put things in perspective.  Here’s a guy who was told when he was 14 that he was going to be the best in the world at something, and maybe the best at it of all people ever.  He’s had people fawning over him his entire life.  He was a millionaire at 18.  He is a two time champion and four time MVP.  And how does he react; he’s happily married with children to his high school girlfriend, he’s close with his high school friends, he appears in the news for charity and his basketball performance, and never once for criminal behavior.  That’s a heck of a lot better than I probably would have done.  Just sayin’.
