Celebrating Georgia Tech Women: Pathway of Progress is the new name of the forthcoming, permanent tribute to the impact of women from Georgia Tech, now under construction near the John Lewis Student Center and Stamps Commons. Set to open in Fall 2024, the physical installation and accompanying digital experience will celebrate 70 graduates, as well as 98 women and events with historical significance to the Institute. 

The Institute is proud to reveal the inaugural alumnae whose names and legacies will be recognized. The historical honorees will be announced this fall.

Inaugural honorees include several College of Sciences alumnae — see the honoree list and learn more about the project here.

Georgia Tech opened the 11th annual Atlanta Science Festival (ASF) with record attendance for Science and Engineering Day. Despite the drizzly weather, about 4,000 people of all ages from throughout metro Atlanta — more than double the number of attendees in 2023 — visited campus on Saturday, March 9, 2024, for the space-themed event. They explored more than 45 exhibitions and hands-on activities related to art, robotics, nanotechnology, chemical and systems engineering, and biology, as well as other STEAM areas. 

Visitors began their investigations at “Earth” (the Kendeda Building for Innovative Sustainable Design), where they picked up a galactic passport specially designed to guide them from building to building — each designated with the name of a planet — and the demonstrations housed within.

At “Mars” (Marcus Nanotechnology Building), attendees measured their height in nanometers, experimented with fruit batteries, and took a window-tour of the largest cleanroom in the Southeast, where semiconductors are developed. Inside “Venus” (Parker H. Petit Biotech Building), budding scientists examined bioluminescent bacteria under a microscope and made Play-Doh models of the human brain. When visiting “Saturn” (Ford Environmental Sciences and Technology Building), visitors studied density by making DIY lava lamps and inspected human brain specimens the way a pathologist would.

“Getting to hold a human brain was cool,” said a 12-year-old participant from Alpharetta. “And I also liked comparing it to the brains of a pig and a mouse.”

Other activities included math games and puzzles, the opportunity to build an artificial hand and a gallery display of research-inspired artwork. Georgia Tech faculty, students, and staff hosted all the demonstrations and served as volunteers who helped Science and Engineering Day guests navigate campus and the demonstration sites.

For many participants, the undoubted highlight was the chance to hear a presentation by former NASA astronaut and Georgia Tech alumnus Shane Kimbrough, MS OR 1998. Kimbrough spent 388 days in space over three missions and served as commander of the International Space Station (ISS) in 2016. He captivated the standing-room-only crowd with photos and descriptions of his time living and working aboard the ISS and answered questions from the kids in the audience.

“It’s really exciting to see all the activities around campus today … we’re inspiring the next generation of scientists and explorers for our country,” Kimbrough said afterward.

The event was a resounding success for Georgia Tech and the Atlanta Science Fair.

Lauren Overton-Kirk, who organized the event for the Institute, said, "Georgia Tech Science and Engineering Day 2024 was so wonderful to share with the community. What started years ago as a day for young scientific exploration became an all-ages, space-themed scientific spectacular. You could feel the passion for learning fill the campus in a way only Georgia Tech could do.”

Both the Georgia Tech and the Atlanta Science Festival teams are looking forward to next year’s Science and Engineering Day.

As one of the founding organizations of the Atlanta Science Festival, Georgia Tech has been deeply invested in sharing the Institute’s innovations with the community,” said Meisa Salaita, ASF co-director. “And that investment was deeply evident on March 9th as they opened their doors to kick off the 11th annual Science Festival. Their students and faculty came out with enthusiasm to showcase science to the public. We couldn't be more thrilled with this partnership — and the many ways Tech has helped us show our community that Atlanta is a science city.”

This season, more than 30 College of Sciences faculty across all six schools and the Undergraduate Program in Neuroscience are recognized by the Institute for their excellence in research and teaching.

Title: RNA Helicase, Nucleolus, and 3D Genome Architecture in Human Pluripotency Control

Major efforts in the field in the past two decades have dissected the transcriptional, post-transcriptional (including translational and posttranslational), and epigenetic mechanisms that underlie the maintenance of mouse and human embryonic stem cells (ESCs), leading to the discovery of many transcription factors, noncoding miRNAs/lncRNAs, translation factors, and epigenetic regulators acting alone or in conjunction to maintain pluripotency. Pluripotency entails unique open chromatin features compared to differentiated cells, and the global chromatin organization of ESCs predicts pluripotency and function. Recent studies have hinted at nucleoli as a central hub for nuclear functions in genome stability, aging, cell fate decisions, and cancer. I will discuss how our recent work has discovered an essential RNA helicase critical for the structural integrity of nucleolus in maintaining hESC pluripotency, and how the regulation and roles of the nucleolus in chromatin organization and genome architecture can be better appreciated to understand stem cells, development, and disease.

Event Details

The skin on our hands and feet collectively makes up roughly 5% of our surface area — at least, when it comes to our bodies. When you look at an important sensory area of the brain called the somatosensory cortex, which receives information about things like touch and pain from everywhere on the body’s surface, that number jumps to about 30%.

Liang Han recently received $550k from the National Science Foundation to uncover where in our nervous system that discrepancy in neural real estate might stem from. 

“The somatosensory cortex is like the output of the whole neural circuit — but the neural circuit takes multiple steps,” explains Han, an associate professor in the School of Biological Sciences. “How does this neural circuit generate such a biased representation, and exactly which neurons are involved?”

Pinning down which step in the neural circuit is causing areas like the hands and feet to take up so much of the somatosensory cortex may give us insights into how our sensory systems evolved — and where best to treat them when things go wrong.

Itching for answers

The somatosensory cortex is on the surface of the brain and receives information from specialized sensors on the surface of the body about touch, bodily movement, pain, temperature, and itch. Though it’s organized in a way that roughly matches our body’s structure — areas receiving information from the feet light up next to areas sensing the legs versus the ears, for example — the surface area of the somatosensory cortex is heavily biased towards certain body parts, like the hands. 

To find out where in the nervous system this bias originates, Han and her team are planning to examine the cellular mechanisms of one particular sensation: itch. Specifically, itch on glabrous (or hairless) skin, like that on the hands and feet.

“We’ve been studying itch sensation for a long time, and our previous study identified a group of neurons that control glabrous skin itch sensation,” says Han. Led by Haley Steele, a former Ph.D. student working with Liang, the research gave Han and her team the ability to isolate and study the neurons responsible for sending glabrous skin itch sensation all the way from the fingertips, through the spinal cord, and finally to the somatosensory cortex in the brain.

Interestingly for Han’s team, recent data collected by Yanyan Xing, a former postdoctoral researcher in the Han lab, suggested that there were potential physical differences in the itch-sensing neural circuits for central body parts (like the torso) versus the overrepresented peripheral body parts (like the hands).

“If you ask me why we started this project, that's why,” says Hand, “because we saw that data and we thought, ‘Oh, this is interesting.’”

Going more than skin deep

Those physical differences are just one potential piece of the puzzle. When it comes to the cellular origins of brain’s sensory biases, there could also be more itch-sensing neurons in peripheral areas of the body, their physiology could be different, their signals could be amplified somewhere down the line (like in the spinal cord or brain stem), or it could be a combination.

Using their previously developed tools to genetically label neurons specific to glabrous skin itch sensation in mice, Han and her team plan on studying all that — plus how these neural circuits develop over time.

“Our nervous system evolved in a way that our central nervous system (brain and spinal cord) allocated more neural resources to those distal (peripheral) parts of the body for sensory processing,” explains Han. From exploring our environment to manipulating objects, having keen sensation in distal body parts like the hands and feet has been crucial for our survival. By understanding these sensory circuits, Han is hopeful that “this study will help us to understand how the nervous system evolved.”

Beyond gaining key insights into the sensory system, understanding this particular sensation may help improve treatments for chronic itch — an experience that roughly one in five people will have in their lifetime. 

“Itch is associated with so many different conditions,” says Han. “Understanding the basic mechanisms of the neural circuit will help us to eventually treat the condition.”

 

This research will be funded by the National Science Foundation.

This news was originally released in the University of Helsinki newsroom. Read the full story here.

In a new study led by Georgia Tech and University of Helsinki, researchers have discovered a mechanism steering the evolution of multicellular life.

Co-authored by the School of Biological Sciences’ Dung Lac, Anthony Burnetti, Ozan Bozdag, and Will Ratcliff, the study, “Proteostatic tuning underpins the evolution of novel multicellular traits”, was published in Science Advances this month, and uncovers how altered protein folding drives multicellular evolution.

The team’s research centers on the ongoing Multicellularity Long Term Evolution Experiment (MuLTEE) experiment, in which laboratory yeast are evolving novel multicellular functions, enabling researchers to investigate how these functions arise.

Among the most important multicellular innovations is the origin of robust bodies: over 3,000 generations, these ‘snowflake yeast’ started out weaker than gelatin but evolved to be as strong and tough as wood.

From an evolutionary perspective, this work highlights the power of non-genetic mechanisms in rapid evolutionary change. 

“We tend to focus on genetic change and were quite surprised to find such large changes in the behavior of chaperone proteins,” says Ratcliff. “This underscores how creative and unpredictable evolution can be when finding solutions to new problems, like building a tough body."

This press release is shared jointly with the UC Irvine newsroom.

The National Science Foundation (NSF) has awarded $15 million to an interdisciplinary team spanning 21 institutions across the country.

The six-year funding will support the Integrative Movement Sciences Institute (IMSI), an innovative group conducting groundbreaking research in the mechanics of muscle control during agile movements in changing environments.

NSF IMSI includes several key Georgia Tech researchers:

  • Co-PI Simon Sponberg, Dunn Family Associate Professor in the School of Physics and School of Biological Sciences
  • Lena Ting, professor and McCamish Foundation Distinguished Chair in Biomedical Engineering and co-director of the Neural Engineering Center
  • Greg Sawicki, associate professor in the School of Mechanical Engineering and the School of Biological Sciences.

“To the best of our knowledge, this is the first US-based integrative center on the fundamental biology of muscle and movement that aims to bridge from the molecule to the whole animal to understand dynamic locomotion,” co-PI Sponberg says.

The research team also includes PI Monica Daley (UC Irvine), and additional Co-PIs Kiisa Nishikawa (Northern Arizona University), Jill McNitt-Gray (USC Dornsife College of Letters, Arts and Sciences), and Anne Silverman (Colorado School of Mines).

Leveraging expertise

“The Georgia Tech contingent will leverage the Institute's expertise in the multiscale biophysics of muscle, neuromechanics, integrative physiology and bio-robotic movement,” Sponberg says, “including the Institute’s expertise in fundamental muscle biology and movement technologies.”

The group will also collaborate with Tom Irving and Weikang Ma at the Argonne National Lab to leverage multiscale imaging, which will help connect the team’s understanding of the function of muscle at the nanoscale to the properties of that tissue during motion.

A central theme of the new Integrative Movement Sciences Institute will bridge fundamental discoveries about the biophysics and physiology of muscle and movement from insects to humans research that Sponberg’s lab specializes in.

Last year, Sponberg also received a prestigious Curci grant to study coordinated movement in hawk moths. The team’s goal is to understand how muscle integrates with the rest of a body’s biology and the surrounding environment to allow animals and humans to move through so many varied environments. 

“Muscle is unlike any other tissue,” Sponberg says. “It enables movement in all animals and allows them to negotiate nearly every environment on this planet. For humans, it is the key piece of our physiology that translates our brain’s intentions into the movement that lets us get around in our world.

Creating models that can understand muscular control in dynamic, complex environments is vital, and could have applications spanning biotechnology, like building more dynamic robotics, and bioeconomy, creating avenues to develop new physical therapy and rehabilitation protocols.

“By integrating across scale and bringing to bear an interdisciplinary team of biologists, biophysicists, and bioengineers that span the scale from molecule to ecosystem, the new Integrative Movement Science Institute will create the next generation of muscle and movement models and experiments to understand locomotion in diverse settings,” Sponberg adds.
