Down-Home Research

One of the things I enjoy most about video production is that it gets me out of the office. Don’t get me wrong, working in the luxury of air conditioning can be really nice in the summer, but anyone can go a little stir-crazy if they spend every single day at a desk. But every now and then, my job takes me places, and during production of our most recent Labors of Lab segment, it took me back home.

Laura Schwab, a senior biology major at Texas A&M who studies aquatic insects, is the star of our latest installment. As I was beginning the storyboarding process for her episode, Laura’s faculty advisor, Dr. David Baumgardner, invited me to film her and a few other students as they trapped insects at the Navasota River. Well, it just so happens I’m originally from Navasota, so this would be a homecoming of sorts for me. Sign me up!

Now, let’s be clear: The Navasota River isn’t what you would call a “pretty” river. It’s muddy, and there’s usually no shortage of algae. But it is buzzing with wildlife, especially the aquatic insects the students were so hoping to capture. And even though I grew up in that area, I’d never actually been near, or in, the Navasota River. This was a shoot I was truly looking forward to, even on a Saturday.

Laura turned out to be an excellent choice for a Labors of Lab spot, and it was quickly apparent that she was Dr. Baumgardner’s right-hand person. Upon our arrival, they immediately divided up the students and waded into the river, where they embarked on separate excursions. While Dr. Baumgardner led two of the students off to catch insects in the river’s current, Laura and two other students went searching for snag, the random sticks and natural debris that protrude from calm parts of the river that often serve as nesting grounds for many water bugs.

It was here that Laura’s natural leadership shined. She carefully chose which area of the river they would scour for snag, all while explaining to her team the reasons for her selection and demonstrating the proper way to collect a specimen. Whenever they found a particularly mossy stick that looked like it might be serve as a decent home for insects, they carefully doused the end of it in an alcohol solution and secured it in a Ziploc bag.

It was fascinating to watch. In the videos I produce, I often only film people talking about their research and, usually, I’ll stage scenes of people pretending to work on their research so it appears as if they’re actually doing something fascinating in the final video. Never have I actually had the chance to film genuine research in progress — until now. The scenes I filmed at the river that day were some of my best, in my opinion. Undergraduate students doing real research, having real fun. You can’t fake that.

Plus, there’s no place like home.

Oh, and speaking of that spot, watch Laura in action and hear her thoughts on doing field work for Dr. Baumgardner’s lab in our latest Labors of Lab episode below:

REU Posters are Now in Session

For the students who traveled from across the state and nation to participate in Texas A&M’s Summer Research Experiences for Undergraduates (REU), the annual Undergraduate Research Poster Session is the program’s pinnacle. It’s here that they get to showcase the results of their research projects and bask in the culmination of two months of grueling lab work and analysis, not to mention all the trial and error in between.

The poster session is not only a well-deserved celebration of their success, it’s also one final benchmark for these young scientists; they get to personally discuss the results of their research projects with their peers and other faculty besides their designated mentors. It boils down to huge opportunity to really show how much they’ve learned over the summer and do a little networking to boot

See what the poster session is all about.

When Math Comes to Life

It’s summertime, and in the Department of Mathematics, that can only mean one thing: SEE-Math. SEE-Math, which is short for the Summer Educational Enrichment in Math Program, is Texas A&M’s annual two-week day camp for gifted students entering the 6th, 7th or 8th grades to explore their potential in mathematics-related fields and led by professor of mathematics Philip B. Yasskin.

Much of the program’s charm lies in its entertaining and engaging activities that demonstrate the many ways math exists naturally in the world around us. Last week, senior lecturer Mila Mogilevsky had the students try their hand at origami, the Japanese technique of folding paper into elaborate figures. While the students certainly enjoyed the art lesson, they also enjoyed learning about the geometry that makes the beautiful paper creations spring to life.

Here’s a quick video of origami in action:

Also, check out last summer’s video to learn more about what exactly SEE-Math is all about:

When Research Gets Wild

Scientists often go to great lengths for their research, but sometimes it gets downright risky.

Grace Smarsh ’14 is a Ph.D. candidate who has been working in the lab of Dr. Michael Smotherman, Texas A&M University biologist and a leading expert on bat behavior. Grace spent a total of 17 months during a three-year period in Tanzania studying the songs of its native heart-nosed bat to probe how their vocal ranges adapt to different social interactions. While on her quest to observe the winged creatures, Grace had to learn to coexist with the land-dwellers of the African bush, from the tiniest of insects to some pretty large cats.

Here’s Grace, discussing some of her encounters and how she coped with her rank in the animal kingdom.

All Work and No Play — OK, Maybe Just a Little Play

If you have that preconceived concept, as I once did, that scientists do nothing all day but merrily toil in their labs, pour ambiguous neon liquids from one beaker to the next and jot incomprehensible equations on a blackboard, well, sorry. That’s fiction.

The truth is that being a scientist can be a downright stressful gig.

Before they can pursue the undiscovered, they have to pursue funding so that they can actually perform the research that’s expected of them. Whenever they do don the stereotypical but regulation-required white lab coat, it’s usually to do the same tedious, non-glitzy experiment multiple times with the hope of coming up with some sort of data worth publishing. Those world-changing discoveries are few and far in between, and even then, more follow-up research must be done, which of course means more grants must be secured. It’s a vicious cycle.

Most of them also teach courses each semester, which involves a fresh new realm of stress. On top of everything else, they have to somehow squeeze in the time to create and plan lectures, hold student office hours and grade assignments and exams. (By the way, scientists and lab techs are among the heaviest coffee drinkers in the U.S.)

Breathing down their necks are supervisors wanting publications, students wanting help with homework and the rest of the world wanting answers to a laundry list of questions on everything from the cosmos to cures. They have obligations to fulfill and deadlines to meet. Normal work hours and weekends are never guaranteed.

To put it bluntly, being a scientist is demanding career. Thankfully, the scientists at Texas A&M, are able to find ways to smile through it all, no matter how strenuous it gets. It’s that whole ‘all work, no play’ notion, and big surprise, they excel at that, too. Here’s a lighthearted look at some of our faculty finding joy in the job(s) they do so well.

Somewhere Over, er, Around the Rainbow

Rainbows — who doesn’t love them? Everyone — no matter what age, no matter how bad their day is going — will stop and admire, even if only for a second or two, those beautiful arches of color whenever they happen to appear.

Our infatuation with them goes back thousands of years. In many religions, they are viewed as a sign or message “from above.” In many cultures, they are a symbol of peace and hope. In this day and age, however, rainbows make fantastic social media fodder, and if there’s been a good rain, it’s almost certain that you’ll find at least one picture of Mr. Roy G. Biv.

So last week after a wet several days, Shana and I took to our Facebook machines to skim the obligatory rainbow pics posted by our friends, and we noticed something rather interesting — several shots of unusually flat, double-rainbows.

Rainbow

Being the curious science enthusiasts that we are, we wanted a logical explanation for these oddities. Shana decided to consult our go-to guy for any inquiry involving the sky — Dr. Nicholas B. Suntzeff, University Distinguished Professor of Physics and Astronomy.

We learned that rainbows are naturally 360 degrees, and half of it lies below the horizon where there is no moisture. As for why our rainbows in question had less arch than normal, Dr. Suntzeff explained:

“It is flat because the photo was taken during the middle of the day. The rainbow is circular around the anti-solar point. Here, the anti-sun must be way below the horizon.”

He also passed along this link that offers a very detailed explanation:

There you have it — rainbows are naturally circular, thus eliminating any hope for ever finding that pot of gold at the end of one.

At least they’re still pretty to look at.

(Incidentally, for those who might want to try that water-hose experiment to see the full 360-degree effect in action, I’d recommend leaving your dog, if not your adorable toddler, inside. Curious? Click here.)

EDITOR’S NOTE: Anything look familiar, from photo to explanation, in this September 30 Astronomy Picture of the Day? Just goes to show this is phenomenal double stuff the world over!

Science: There’s a Magic to It

“It’s magic!”

It’s hard to hear yourself think, much less anything else, in a classroom full of sixth-graders, but that excited shriek caught my attention.

YAP_demo_PhysicsI was taking photographs of a Physics Show demonstration for the Youth Adventure Program (YAP) in the Mitchell Physics Building last month. The kids were in awe over a tiny cube-shaped magnet that was floating in midair around a circular disc. And indeed, it gave the appearance of something on the supernormal side of things.

“It’s not magic – it’s physics,” noted Dr. Tatiana Erukhimova, senior lecturer and champion of the Department of Physics and Astronomy’s premier outreach extravaganza.

Technically, that’s true. We actually were witnessing the principles of superconducting levitation at work. Superconductors expel magnetic fields, so when the disc is cooled to its point of superconductivity (with the help of some liquid nitrogen), the repulsion is so strong that the magnet appears to be suspended in air.

Science may be the fabric of what we know as “magic,” but it takes a lot of creativity Tatiana_YAP(and perhaps some charisma, too) to capture an audience’s imagination using only everyday objects, especially when that audience is hyperactive pre-teens. People like Tatiana, and also Dr. James Pennington who spearheads the Department of Chemistry’s Chemistry Roadshow, are masters of this.

To me, there’s a little bit of magic in that.
