Combining Up-Close Views of Science, Nature With the Magic of Light

Zinnia stamen by Thomas Barlow, Duke University

Thomas Barlow ’21 finds inspiration in small everyday things most people overlook: a craggy lichen growing on a tree, a dead insect, the light reflected by a pane of glass. Where we might see a flower, Barlow looks past the showy pink petals to the intricate parts tucked within.

The 20-year-old is a Duke student majoring in biology. By day, he takes classes and does research in a lab. But in his spare time, he likes to take up-close photographs using objects he finds outside or around the lab: peach pits, fireflies. But also pipettes, pencils.

Barlow got interested in photography in middle school, while playing around with his dad’s camera. His dad, a landscape architect, encouraged the hobby by enlisting him to take photos of public parks, gardens and playgrounds, which have been featured on various architects’ websites and in national publications such as Architecture Magazine. But “I always wanted to get closer, to see more,” Barlow said.

In high school he started taking pictures of still lifes. But he didn’t just throw flowers and fruit onto a backdrop and call it art. His compositions were a mishmash of insects and plants arranged with research gadgets: glass tubes, plastic rulers, syringes, or silicon wafers like those used for computer chips.

“I like pairing objects you would never find together normally,” Barlow said. “Removing them from their context and generating images with interesting textures and light.”

Sometimes his mother sends him treasures from her garden in Connecticut to photograph, like the pale green wings of a luna moth. But mostly he finds his subjects just steps from his dorm room door. It might be as easy as taking a walk through Duke Gardens or going for one of his regular runs in Duke Forest.

Having found, say, a flower bud or bumblebee, he then uses bits of glass, metal, mirrors and other shiny surfaces — “all objects that interact with light in some interesting way” – to highlight the interaction of light and color.

“I used to be really obsessed with dichroic mirrors,” pieces of glass that appear to change colors when viewed from different angles, Barlow said. “I thought they were beautiful objects. You can get so many colors and reflections out of it, just by looking at it in different ways.”

In one pair of images, the white, five-petaled flowers of a meadow anemone are juxtaposed against panels of frosted glass, a pipette, a mechanical pencil.

Another image pair shows moth wings. One is zoomed in to capture the fine details of the wing scales. The other zooms out to show them scattered willy-nilly around a shimmering pink circle of glass, like the remnants of a bat’s dinner plate.

For extreme close-ups, Barlow uses his Canon DSLR with a microscope objective mounted onto the front of a tube lens. Shooting this close to something so small isn’t just a matter of putting a bug or flower in front of the camera and taking a shot. To get every detail in focus, he takes multiple images of the same subject, moving the focal point each time. When he’s done he’s taken hundreds of pictures, each with a different part of the object in focus. Then he merges them all together.

At high magnification, Barlow’s flower close-ups reveal the curly yellow stamens of a zinnia flower, and the deep red pollen-producing parts of a tiger lily.

“I love that you can see the spikey pollen globules,” Barlow said.

When he first got to Duke he was taking photos using a DIY setup in his dorm room. Then he asked some of the researchers and faculty he knew if there was anything photography-related he could do for their labs.

“I knew I was interested in nature photography and I wanted to practice it,” Barlow said.

One thing led to another, and before long he moved his setup to the Biological Sciences building on Science Drive, where he’s been photographing lichens for Daniele Armaleo and Jolanta Miadlikowska, both lichenologists.

“A lichen photo might not seem like anything special to an average person,” Barlow said. “But I think they’re really stunning.”

Science in haiku: // Interdisciplinary // Student poetry

On Friday, August 2, ten weeks of research by Data+ and Code+ students wrapped up with a poster session in Gross Hall where they flaunted their newly created posters, websites and apps. But they weren’t expecting to flaunt their poetry skills, too! 

Data+ is one of the Rhodes Information Initiative programs at Duke. This summer, 83 students addressed 27 projects addressing issues in health, public policy, environment and energy, history, culture, and more. The Duke Research Blog thought we ought to test these interdisciplinary students’ mettle with a challenge: Transforming research into haiku.

Kicking Off a Summer of Research With Data+

If the May 28 kickoff meeting was any indication, it’s going to be a busy summer for the more than 80 students participating in Duke’s summer research program, Data+.

Offered through the Rhodes Information Initiative at Duke  (iiD), Data+ is a 10-week summer program with a focus on data-driven research. Participants come from varied backgrounds in terms of majors and experience. Project themes range  from health, public policy, energy and environment, and interdisciplinary inquiry.

“It’s like a language immersion camp, but for data science,” said Ariel Dawn, Rhodes iiD Events & Communication Specialist. “The kids are going to have to learn some of those [programming] languages like Java or Python to have their projects completed,” Dawn said.

Dawn, who previously worked for the Office of the Vice Provost for Research, arrived during the program’s humble beginnings in 2015. Data+ began in 2014 as a small summer project in Duke’s math department funded by a grant from the National Science Foundation. The following year the program grew to 40 students, and it has grown every year since.

Today, the program also collaborates with the Code+ and CS+ summer programs, with  more than 100 students participating. Sponsors have grown to include major corporations such as Exxonmobil, which will fund two Data+ projects on oil research within the Gulf of Mexico and the United Kingdom in 2019.

“It’s different than an internship, because an internship you’re kind of told what to do,” said Kathy Peterson, Rhodes iiD Business Manager. “This is where the students have to work through different things and make discoveries along the way,” Peterson said.

From late May to July, undergraduates work on a research project under the supervision of a graduate student or faculty advisor. This year, Data+ chose more than 80 eager students out of a pool of over 350 applicants. There are 27 projects being featured in the program.

Over the summer, students are given a crash course in data science, how to conduct their study and present their work in front of peers. Data+ prioritizes collaboration as students are split into teams while working in a communal environment.

“Data is collected on you every day in so many different ways, sometimes we can do a lot of interesting things with that,” Dawn said.  “You can collect all this information that’s really granular and relates to you as an individual, but in a large group it shows trends and what the big picture is.”

Data+ students also delve into real world issues. Since 2013, Duke professor Jonathan Mattingly has led a student-run investigation on gerrymandering in political redistricting plans through Data+ and Bass Connections. Their analysis became part of a 205-page Supreme Court ruling.

The program has also made strides to connect with the Durham community. In collaboration with local company DataWorks NC, students will examine Durham’s eviction data to help identify policy changes that could help residents stay in their homes.

“It [Data+] gives students an edge when they go look for a job,” Dawn said. “We hear from so many students who’ve gotten jobs, and [at] some point during their interview employers said, ‘Please tell us about your Data+ experience.’”

From finding better sustainable energy to examining story adaptations within books and films, the projects cover many topics.

A project entitled “Invisible Adaptations: From Hamlet to the Avengers,” blends algorithms with storytelling. Led by UNC-Chapel Hill grad student Grant Class, students will make comparisons between Shakespeare’s work and today’s “Avengers” franchise.

“It’s a much different vibe,” said computer science major Katherine Cottrell. “I feel during the school year there’s a lot of pressure and now we’re focusing on productivity which feels really good.”

Cottrell and her group are examining the responses to lakes affected by multiple stressors.

Data+ concludes with a final poster session on Friday, August 2, from 2 p.m. to 4 p.m. in the Gross Hall Energy Hub. Everyone in the Duke Community and beyond is invited to attend. Students will present their findings along with sister programs Code+ and the summer Computer Science Program.

How Many Neuroscientists Does it Take to Unlock a Door?

Duke’s Summer Neuroscience Program kicked off their first week of research on June 4 with a standard morning meeting: schedules outlined, expectations reiterated, students introduced. But that afternoon, psychology and neuroscience professor Thomas Newpher and undergraduate student services coordinator Tyler Lee made the students play a very unconventional get-to-know-you game — locking them in a room with only one hour to escape.

Not the usual team building activity: Students in Duke’s 8-week Summer Neuroscience Program got to know each other while locked in a room.

Bull City Escape is one of a few escape rooms in the Triangle, but the only one to let private groups from schools or companies or families to come and rent out the space exclusively. Like a live-in video game, you’re given a dramatic plot with an inevitably disastrous end: The crown jewels have been stolen! The space ship is set to self-destruct! Someone has murdered Mr. Montgomery, the eccentric millionaire! With minutes to go, your rag-tag bunch scrambles to uncover clues to unlock locks that yield more clues to yet more locks and so on, until finally you discover the key code that releases you back to the real world.

This summer’s program dips into many subfields, in hopes of pushing the the 16 students (most of them seniors) toward an honors thesis. According to Newpher, three quarters of the senior neuroscience students who participated in the 2018 SNP program graduated with distinction last May.

From “cognitive neuro” that addresses how behavior and psychology interacts with your neural network, to “translational neuro” which puts neurology in a medical context, to “molecular and cellular neuro” that looks at neurons’ complex functions, these students are handling subjects that are not for the faint of heart or dim of mind.

But do lab smarts carry over when you’re locked in a room with people you hardly know, a monitor bearing a big, red timer, blinking its way steadily toward zero?

Apparently so. The “intrepid team of astronauts” that voyaged into space were faced with codes and locks and hidden messages, all deciphered with seven minutes left on the clock, while the “crack-team of detectives” facing the death of Mr. Montgomery narrowly escaped, with less than a minute to spare. At one point, exasperated and staring at a muddled bunch of seemingly meaningless files, a student looked at Dr. Newpher and asked, “Is this a lesson in writing a methods section?”

The Bull City Escape website lists creative problem-solving, focus, attention to detail, and performance under pressure as a few of the skills a group hones by playing their game — all of which are relevant to this group of students, many of whom are pre-med. But hidden morals about clarity and strength-building aside, Newpher picked the activity because it allows different sides of people’s personalities to come out: “When you’re put in that stressful environment and the clock is ticking, it’s a great way to really get to know each other fast.”
