At Biotech Party, Gender Diversity Means Cocktail Waitresses

Outside the Exploratorium, an airy event space on San Francisco’s waterfront, a long line of mostly male biotechnology investors and executives waited to get into a party.

The ballrooms of the Westin St. Francis hotel were packed with rows of men in blue and gray suits. Outside the hotel, where attendees gather for coffee, was about the same -- of 47 people sitting on one side of the square outside the conference hotel, two were women. Of those, one was in media relations. There was no line for the women’s bathroom.

LifeSci’s McDonald says it’s just reality that the industry and its investors skew male. That’s why he hired the models.

“When you think about going to a party, when you don’t have any models, it’s going to be 90/10, or even greater, male-to-female,” he said. “Adding in some females changes the dynamic quite a bit.”

I have a lot of friends who are premeds, so they definitely aren't all bad. That said, some of them are pretty hard to be in class with. Especially the ones who are SUPER competitive - they dominate office hours and take up the instructor's time with questions that are sometimes only relevant to themselves. One of my TAs was complaining about one of the that argued with him for 30 minutes over half a point. There's a point where it goes past acceptable academic competition.

At the risk of being incredibly whiny, what exactly is everyone's beef with med students? D: I just finished my biology degree with pre-med and I guess I was just surrounded by med students because I do not understand

It’s just exhausting to be in a class you enjoy and are taking because you want to do science and be surrounded by students who are constantly complaining about how much they hate it, and don’t need it, and are only taking it because it’s going to be on the MCAT. Certainly not all pre-meds are like that, but even the 10% who constantly ask questions about if they’re going to get an A and look down at the mere science students kind of ruin it when you have to deal with them in every class.

I will say, a large part of the problem isn’t even pre-med students themselves, it’s the fact that biology departments have to bear the burden of the majority of their students being pre-professional in some capacity, who have completely different needs than pre-doctoral students who want to be biologists. Bio programs end up teaching to the MCAT almost out of necessity, which does a disservice to the students who want to be scientists. 

I know that at my university, I considered switching to bio from chem, but ended up staying in the science and engineering college because the bio college was so focused on pre-professional students that they did a really poor job preparing you to be an actual scientist. Just based on the classes I took for my biochem minor, it was really obvious. I suspect that this is the case at a lot of schools, which sort of compounds the issues and makes pre-doctoral students frustrated with pre-meds, even though it’s not their fault directly.

PUMPKIN-SPICED FLUORESCENCE

Inside a pumpkin, seeds don’t need much chlorophyll—the molecule that helps plants convert light into food—because there isn’t a lot of light deep inside the fruit’s flesh. Instead of chlorophyll, the green seeds are chock-full of protochlorophyllide, a highly fluorescent molecule that glows orange-red under ultraviolet light and can be converted into chlorophyll a by an enzyme in the seeds. The enzyme reduces protochlorophyllide to produce chlorophyll when the enzyme encounters light, which occurs only after the seed has left the pumpkin and therefore needs to start producing its own food so it can grow. Helmut Brandl, a science communicator and professor at ETH Zurich, extracted this protochlorophyllide by grinding up pumpkin seeds and mixing them with nail polish remover (bottom row).

Look Deep Inside

daniel stoupin, a doctoral candidate in marine biology at the university of queensland, has photographed a variety of coral species from the great barrier reef using full spectrum light to reveal fluorescent pigments that would otherwise be invisible to the naked eye. (see more at bioquest studios)

coral growth rates in the great barrier reef have plummeted 40 percent in the last 40 years, a result, according to a recent study, of increased ocean acidification. since the beginning of the industrial revolution, about one third of the carbon dioxide that has been released into the atmosphere as a result of fossil fuels has been absorbed by the oceans, where it in turn prevents coral from using a mineral called aragonite to make their calcified skeletons.

new modelling has also shown that if ocean waters continue to warm by even one degree, which most now see as unstoppable, the coverage of corals on the great barrier reef could decline to less than 10 percent, which is a level too low for the reef to mount a recovery.

further complicating matters for the coral is the plastic detritus left by humans which now litter the oceans and which the coral now consume. unable to expel the plastic bits and thus take in nutrients, the coral slowly starve. a recent study found that each square kilometre of australia’s sea surface water is contaminated with approximately 4,000 pieces of tiny plastic.
