Biofluorescence

Biofluorescence

Here’s a quick news bite about the discovery of a sea turtle which has a fluorescent shell and possibly parts of the head and limbs. I’ll try to dig up more info and edit the post later.

You can read about bioluminescence and fluorescent proteins here:

I’ll have to read more about this later.

Liquid water flows on present-day Mars! Researchers using our Mars Reconnaissance Orbiter detected signatures of hydrated minerals on slopes where mysterious dark streaks are seen on the Red Planet. Scientists say it’s likely a shallow subsurface flow, with enough water wicking to the surface to explain the darkening. This is a significant science discovery on our quest to send humans on a #JourneyToMars. Details: http://go.nasa.gov/1Lh2IvA

What’s in the fold?

Congratulations! You’re a TIM (triose phosphate isomerase) barrel.

You have multiple talents and can fit in with lots of different social groups. On the surface, you might seem indistinguishable from other TIM barrels, but, in fact, you are totally unique in your subtle way.

We know how fickle some proteins can be, so we developed the all-in-one Amicon® Pro system for protein purification and antibody labeling.

Mentioning Amicon gives me flashback nightmares of grad school, filtering human red blood cell lysate (broken cells) so that I could harvest hemoglobin.

I had to search Protein Database (PDB) to see if I can display a TIM barrel on the 3D wall at work.

You can use the Jmol viewer to explore TIM.

On the right hand side, where it says Style, you can change between the different types (models) of depicting a structure: ball & stick, cartoon, space-filling, etc. Unfortunately I don’t have time for a lengthy post to explain the different models or to write more about TIM.

On the last question, in case you don’t know who Maud Menton is, she’s the Menton in the Michaelis-Menton equation. She’s also an alum of the University of Chicago.

American adults get a D in science; 22% confuse astronomy and astrology

The test isn’t particularly hard but then again, I tend to surround myself with smart friends. Based on some of the nonsense I’ve been reading in the news, it would be interesting to see how some of the presidential candidates would fare on the Pew research test. Try it yourself.

I got them all correct. I’d be upset if I got any of them wrong. I’m a scientist for crying out loud.

“So what do you do for a living?” I always cringe a bit when that question comes up among strangers,

I also dislike that question. I tell people I’m a scientist or that I do cancer research. Sometimes people are startled by that answer and say something like, “you don’t look like a scientist”. Which reminds me of a post about perceptions of what a scientist looks like.

Hey scientist, smile!

I try to strike a balance between explaining what I do and not talking over people’s head. It’s really an exercise to not use jargon. Most occupations have jargon and we often forget that jargon is almost a foreign language to everyone else. My wife and I had fried chicken for lunch while running errands yesterday. The girl at the cash register asked if the half order of dark was mine. I ordered 2 thighs and 2 drumsticks and it took a second to make the connection. Neither of us are stupid. Her co-worker chimed in and said, “you have to learn that not everyone knows that a half dark order is 2 thighs and 2 legs”.

One aspect of being a scientist that people do not realize is that great scientists are also creative. Without creativity, you’ll always be thinking inside the box. You will make incremental steps.

I don’t think I’m exceptionally smart. It does take a lot of work and effort to be a scientist as Brian said. I try to surround myself with people who are smarter. That keeps me humble and on my toes. I also remind myself that every person knows something that I don’t and I certainly don’t know everything. I enjoy learning and that’s why I’m a scientist.

You Are Not Stupid

“So what do you do for a living?” I always cringe a bit when that question comes up among strangers, because when I reveal that I’m an astrophysics professor the response is almost always the same. “Um…wow…. You must be really smart!”

While it’s often intended as a compliment, it really isn’t. Smart didn’t allow me to become an astrophysicist. Hard work, dedication and the support of family and friends did. It’s also one of the most deeply divisive misconceptions about scientists that one can have: scientists are smarter than you. Part of this stems from the idolization of brilliant scientists. Albert Einstein was so smart that fictitious quotes are attributed to him. Media buzzes whenever Stephen Hawking says something about black holes. Any quote by Neil Tyson is a sure way to get likes on Facebook. We celebrate their genius and it makes us feel smart by association. But this stereotype of the “genius scientist” has a dark side.

For one there’s expectation that to do science you must be super smart. If you struggle with math, or have to study hard to pass chemistry, you must not have what it takes. The expectation to be smart when you don’t feel smart starts to foster a lack of self confidence in your abilities. This is particularly true if you’re a girl or minority where cultural biases presume that “your kind” aren’t smart, or shouldn’t be. Lots of talented children walk away from science because they don’t feel smart.

Then there’s the us vs. them mentality that arises from the misconception. Scientists (and fans of science) are smart. Smarter than you. You are stupid. But of course, you’re not stupid. You know you’re not stupid. The problem isn’t you, it’s the scientists. Scientists are arrogant. For example, when I criticized a particular science website for intentionally misleading readers, the most popular rebuttal was that I (as a scientist) was being elitist.

Where this attitude really raises its head is among supporters of fringe scientific ideas. Some of the strongest supporters of alternative scientific ideas are clearly quite intelligent. Presidential hopeful and evolution denier Ben Carson is a neurosurgeon. Pierre Robitaille made great advances in magnetic resonance imaging, but adamantly believes that the cosmic microwave background comes from Earth’s oceans. Physicist and Nobel laureate Ivar Giaever thinks global warming is a pseudoscience on the verge of becoming a “new religion.” None of these folks are stupid.

If there’s one thing most people know about themselves it’s that they’re not stupid. And they’re right. We live in a complex world and face challenges every day. If you’re stupid, you can quickly land in a heap of unpleasantness. Of course that also means that many people equate being wrong with being stupid. Stupid people make the wrong choices in life, while smart people make the right ones. So when you see someone promoting a pseudoscientific idea, you likely think they’re stupid. When you argue against their ideas by saying “you’re wrong,” what they’ll hear is “you’re stupid.” They’ll see it as a personal attack, and they’ll respond accordingly. Assuming someone is stupid isn’t a way to build a bridge of communication and understanding.

One of the things I love about science is how deeply ennobling it is. Humans working together openly and honestly can do amazing things. We have developed a deep understanding of the universe around us. We didn’t gain that understanding by being stupid, but we have been wrong many times along the way. Being wrong isn’t stupid.

Sometimes it’s the only way we can learn.
