It is a fact that climate is changing, but how much and how fast are the subject of debate. Georgia Tech researchers are attempting to answer these questions for peatlands, a freshwater wetland ecosystem. Their recent work indicates that warming of peatlands increases microbial production of greenhouse gases, releases more methane than carbon dioxide, reduces microbial diversity, and alters the composition of microbial communities in peat soils.
In April, the Center for Teaching and Learning celebrated students and postdoctoral scholars who have contributed to the learning environment at Georgia Tech at the 2019 TA and Future Faculty Awards Day.
Desert snakes slithering across the sand at night can encounter obstacles such as plants or twigs that alter the direction of their travel -- and cause them to mimic aspects of light or subatomic particles when they encounter a diffraction grating.
As university research has become more complex and interdisciplinary, laboratory teams have grown in size, with increasing numbers of specialists in such areas such as statistical analysis, electron microscopy or mass spectrometry.
The fish killer and the fish live in perfect harmony: But how the clownfish thrives in the venomous tentacles of the anemone remains a mystery. A new study tackles the iconic conundrum from the microbial side by watching bacterial colonies shift in fish mucus, as the clownfish cozy up to anemones.
Scientists from around the world have now observed 10 black hole collisions and a merger of two binary neutron stars using LIGO and the European-based Virgo gravitational wave detector. A new catalog inventories those events.
Do genes fire off signals to cause some behaviors? Science is getting closer to finding out. Researchers were able to directly match gene regulation with ritual mating behavior in fish. Their research field may give some insight into autism spectrum disorder.
The 2011 National Theatre stage adaptation of Frankenstein, written by Nick Dear and directed by Danny Boyle, highlights a construction of masculinity that relies on and normalizes violence against women. Though Shelley’s narrating scientist only briefly mentions his interactions with his female creature and brushes over his fiancée’s death, on stage, Victor performs necrophilic acts to taunt his creation/counterpart. Later, he and the audience watch while the creature rapes and then murders Elizabeth in a brutal simulacrum of sexual climax. These scenes of violence against women, performed frankly, do not allow for the possibility of emotional recovery or resolution on the part of the audience, but instead become a parody of desire and agency. They thus reinforce violent stereotypes as the basis of toxic masculinity.
Either exorbitantly expensive fuel or insanely hot temperatures have made fuel cells a boutique proposition, but now there's one that runs on cheap methane and at much lower temperatures. This is a practical, affordable fuel cell and a "sensation in our world," the engineers say.
Imagine your liver being just a big puddle. Some organelles in your cells are exactly that including prominent ones like the nucleolus. Now a synthetic organelle engineered in the lab shows how such puddle organs can carry out complex life-sustaining reaction chains.
Black holes form when stars die, allowing the matter in them to collapse into an extremely dense object from which not even light can escape. Astronomers theorize that massive black holes could also form at the birth of a galaxy, but so far nobody has been able to look far enough back in time to observe the conditions creating these direct collapse black holes (DCBH).
A simulator that comes complete with a virtual explosion could help the operators of chemical processing plants – and other industrial facilities – learn to detect attacks by hackers bent on causing mayhem. The simulator will also help students and researchers understand better the security issues of industrial control systems.
For ants and robots operating in confined spaces like tunnels, having more workers does not necessarily mean getting more work done. Just as too many cooks in a kitchen get in each other’s way, having too many robots in tunnels creates clogs that can bring the work to a grinding halt.
Injured elderly muscle tissue heals slowly or not at all, and Duchene MS sufferers often die when their diaphragm muscles weaken then give out. A new hydrogel that packs donor muscle stem cells could someday help these patients recover and live longer.
A previously overlooked predator— a thumbnail-sized snail—could be increasing the pressure on coral reefs already weakened by the effects of overfishing, rising ocean temperatures, pollution and other threats.
Georgia Tech Ph.D. students and postdocs host AbGradCon 2018 on June 4-8, 2018. The annual Astrobiology Graduate Conference provides a unique setting for graduate students and early-career scientists to share their research, collaborate, and network.
Despite the wealth of information about how bacteria communicate, little is known about how quorum sensing proceeds during an infection. Georgia Tech researchers describe for the first time how close bacteria need to be to “talk” in an environment similar to chronic infection in cystic fibrosis.
Most of what we know today about deadly bacteria such as Pseudomonas aeruginosa was obtained from studies done in laboratory settings. Research reported May 14 in the journal Proceedings of the National Academy of Sciences shows that this laboratory-based information may have important limits for predicting how these bugs behave once they’ve invaded humans.
Certain minuscule cancer signals easily evade detection, but perhaps no longer. Biomarkers made of glycoproteins are bound to get snared in the tentacles of this chemical octopus that Georgia Tech chemists devised over several years. The monstrous molecule could also be a windfall for the rising field of glycoscience.
Postdocs Karan Jani and Karelle Sielez, at the Center for Relativistic Astrophysics, and Nastassia Patin, at the School of Biological Sciences, are recognized for outstanding work at the 2017 Georgia Tech Postdoctoral Research Symposium.
In anticipation of the July 1 implementation date for the new state law allowing licensed gun owners to carry weapons on public college campuses, Georgia Tech leaders held an information session with the campus community June 14.
On the early Earth, methane production could have persisted in rust-free patches of ancient seas. Unlike the situation in today’s well-aerated oceans, where most natural gas produced on the seafloor is consumed before it can reach the surface, most of this ancient methane would have escaped to the atmosphere to trap heat from the early sun.
A little empathy can go a long way toward ending infectious disease outbreaks. That’s a conclusion from researchers who used a networked variation of game theory to study how individual behavior during an outbreak of influenza – or other illness – affects the progress of the disease, including how rapidly the outbreak dies out.
Following Dean Gary May’s confirmation as the next chancellor at the University of California Davis, Provost Rafael L. Bras has named a search committee to launch a national and international search for a new dean of the College of Engineering. The committee will be chaired by Julia Kubanek, associate dean for Research, College of Sciences; professor of Biological Sciences; and professor of Chemistry and Biochemistry.
Researchers have successfully identified biological signatures in pediatric patients with newly diagnosed Crohn’s disease (CD) capable of predicting whether a child will develop disease-related complications requiring major surgery within three to five years. The results of this research, “Prediction of complicated disease course for children newly diagnosed with Crohn’s disease: a multicentre inception cohort study,” have been published in the journal, The Lancet.
Triboelectric nanogenerators (TENG) convert mechanical energy harvested from the environment to electricity for powering small devices such as sensors or for recharging consumer electronics. Now, researchers have harnessed these devices to improve the charging of molecules in a way that dramatically boosts the sensitivity of a widely-used chemical analysis technique.
Tens of thousands of patients each year are diagnosed with heart valve disease, with many in need of lifesaving surgery to treat the condition.
Now, researchers at the Georgia Tech Manufacturing Institute -- including ISyE Professor Chuck Zhang -- are working on a tool that could help cardiologists care for patients with the disease. Using highly detailed imaging from CT scans, engineers are using 3-D printers to make an exact model of an individual patient’s heart valve.
In the not-too-distant future, water and energy harvested by individuals, communities and other non-traditional systems – think rain barrels, grey water recycling, solar panels and windmills – may be integrated into centralized municipal networks.
With these added resources flowing into existing municipal systems, water and energy supplies around the world could become more sustainable, more resilient, and more secure in the face of potential natural disasters and possible security threats.
However, according to School of Computational Science and Engineering Assistant Professor Bistra Dilkina, getting to a point where this is possible on a broad scale is not going to be easy.
As Open Enrollment season approaches, many employees may be thinking about how their health or families could change in the coming year. One important life change that requires benefits planning is welcoming a new child.
A research team from the Georgia Institute of Technology and ExxonMobil has demonstrated a new carbon-based molecular sieve membrane that could dramatically reduce the energy required to separate a class of hydrocarbon molecules known as alkyl aromatics.
When early terrestrial animals began moving about on mud and sand 360 million years ago, the powerful tails they used as fish may have been more important than scientists previously realized. That’s one conclusion from a new study of African mudskipper fish and a robot modeled on the animal.
With Tuesday’s announcement of the Final Rule for the Fair Labor Standards Act (FLSA), Georgia Tech Human Resources understands there may be a significant amount of questions about what it means for campus.
The last few years have seen a revolution in the way that diagnosticians evaluate the genetic mechanisms that cause debilitating congenital abnormalities from heart defects to intellectual disability. Whole genome sequencing (WGS) is just around the corner, and in about a third of cases it finds a strong candidate mutation, sometimes suggesting new treatment options, but otherwise bringing understanding to parents. But what about all of the other cases?
In the water above natural oil seeps in the Gulf of Mexico, where oil and gas bubbles rise almost a mile to break at the surface, scientists from the Georgia Institute of Technology, Columbia University and Florida State University have discovered something unusual: phytoplankton, tiny microbes at the base of the marine food chain, are thriving.
Researchers at Carnegie Mellon University who develop snake-like robots have picked up a few tricks from real sidewinder rattlesnakes on how to make rapid and even sharp turns with their undulating, modular device.
A weekly meditation class, which is suitable for all levels of experience, is designed to teach participants how to relieve stress, achieve deep relaxation, gain breath and body awareness, and achieve greater mental clarity.
Researchers have created a broad color palette of electrochromic polymers, materials that can be used for sunglasses, window tinting and other applications that rely on electrical current to produce color changes. The materials could allow sunglasses that change from clear to colored in seconds, at the push of a button.
The microneedles, ranging in length from 400 to 700 microns, could provide a new way to deliver drugs to specific areas within the eye relevant to these diseases. By targeting the drugs only to specific parts of the eye instead of the entire eye, researchers hope to increase effectiveness, limit side effects and reduce the amount of drug needed.
For new faculty, the university environment is not necessarily new but can be an overwhelming entity of operations during the first years. At Tech, many find their place among their peers on campus through mentoring.
Researchers have developed an automated imaging technique for measuring and analyzing the root systems of mature plants. The work could help plant scientists improve food crops to help meet the needs of a growing world population.
Industrial wet spinning processes produce fibers from polymers and other materials by using tiny needles to eject continuous jets of liquid precursors. The electrically charged liquids ejected from the needles normally exhibit a chaotic “whipping” structure as they enter a secondary liquid that surrounds the microscopic jets. A research team has now figured out how to convert the standard chaotic waveform to a stable helical form.
Do you want help exploring all of the career options available to PhD Scientists and Engineers going into the biomedical workforce? The NIH funded Atlanta Broadening Experiences in Scientific Training (BEST) Program has been established to help Emory and Georgia Tech PhD students and postdocs in the biological, biomedical, bio-focused STEM fields explore career paths beyond faculty positions.
According to a study published in the journal Proceedings of the National Academy of Sciences, co-evolutionary changes in species may reverse traditional predator-prey population cycles, creating the appearance that prey are eating the predators.
The “general faculty” designation will be retired July 1 as a result of the Academic Faculty, Academic Senate, and General Faculty’s April 22 approval of revisions to the Faculty Handbook that streamline definitions of faculty. The vote followed a second reading of the proposed changes; the first reading occurred at the groups’ joint Feb. 18 meeting.
From time to time, living cells will accidently make an extra copy of a gene during the normal replication process. Throughout the history of life, evolution has molded some of these seemingly superfluous genes into a source of genetic novelty, adaptation and diversity. A new study shows one way that some duplicate genes could have long-ago escaped elimination from the genome, leading to the genetic innovation seen in modern life.
Researchers at Georgia Tech have created a prototype software, Gyrus, that takes extra steps to prevent malware from sending spam emails and instant messages, and blocking unauthorized commands such as money transfers.
Since opening last fall, Tech’s Office of Postdoctoral Services has been connecting the dots among postdoctoral fellows, faculty mentors, and the administration by hosting networking events, orientation sessions, and workshops.
Did you know that the third week of September is National Postdoctoral Appreciation Week? That makes this a fitting time to announce the opening of the new Office of Postdoctoral Services, which is under the Office of the Vice Provost for Graduate Education and Faculty Affairs.
