The news that some members of the gorilla troop at the San Diego Zoo have tested positive for the virus that causes COVID-19 ramps up the urgency for protecting great apes in the wild from exposure, warns Thomas Gillespie, an Emory disease ecologist. 

“This first known transmission to apes confirms what we strongly suspected — that one of our closest living relatives is susceptible to the novel coronavirus,” says Gillespie, an associate professor in Emory’s Department of Environmental Sciences and Rollins School of Public Health. “More than ever, it’s a race against time. If gorillas in the wild become infected it will be a much more dangerous scenario because we won’t have the ability to contain it.” 

In March, Gillespie co-authored a Nature commentary warning that non-human great apes are susceptible to human respiratory diseases and that COVID-19 could prove devastating to animals on the brink of extinction. 

The non-human great apes include chimpanzees, bonobos and gorillas, which live in equatorial Africa, and orangutans, which are native to the rainforests of Indonesia and Malaysia. The International Union for Conservation of Nature (IUCN) lists chimpanzees and bonobos as endangered species, while gorillas and orangutans are critically endangered. 

Even exposure to viruses that have mild effects in people, such as those causing the common cold, have been associated with mortality events in wild primates. 

The San Diego Zoo Safari Park reported that it conducted tests for the presence of the SARS-CoV-2, the coronavirus that causes COVID-19, after two of its gorillas began coughing. On January 11, the test results confirmed the presence of the virus in some of its gorillas, the zoo announced in a release, adding that it suspects that the virus was transmitted by an asymptomatic staff member, despite the strict prevention protocols in place. 

Great apes, in particular, are at risk from many human diseases due to our close relationship. Chimpanzees and bonobos are our nearest living relatives, sharing about 99 percent of human DNA, while gorillas are our next closest relatives, sharing 98 percent of our DNA. 

The great apes also share key sites within the ACE2 receptor protein with humans that allow SARS-CoV-2 to bind onto cells and infect them. 

Gillespie is a member of an IUCN task force focused on mitigating the impact of COVID on great apes and other primates. He is working with governments and organizations in Africa, including the Jane Goodall Institute, to provide scientifically-informed guidance on protecting wild apes during the pandemic as tourism, research and other activities that lead to human-ape overlap resume. The IUCN Save Our Species Program provided funding to support communities impacted by the loss of great ape tourism, to help prevent people from resorting to poaching animals or logging their habitats. Some of those funds are set to run out soon. 

Gillespie’s lab is also developing a spatially-explicit model to investigate key factors that may affect the spread of the virus among wild primates, so that governments and organizations can prioritize efforts to protect the animals. 

“What’s happened in San Diego has brought the pandemic risks for great apes back into the spotlight,” Gillespie says. “Great apes are our closest relatives and many of them are critically endangered, on the verge of extinction. We’ve gained a lot of insights into our own health and biology by studying these animals. They are important not just to ecosystems but to giving us insights into understanding our own selves and our evolutionary past.”

Valuing 'natural capital' vital to avoid next pandemic, global experts warn

Every economic decision needs to take natural capital into account to avoid an even bigger catastrophe than the current pandemic, says Emory disease ecologist Thomas Gillespie.

By Carol Clark

Pandemics will emerge more often, kill more people than COVID-19 and do even more damage to the world economy unless urgent steps are taken to address risk drivers such as deforestation, warns a major new report on biodiversity and pandemics. 

The report, entitled “Escaping the Era of Pandemics,” was made public by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), which includes United Nations members from more than 100 governments. The report is the result of an urgent workshop organized by the IPBES. The workshop brought together 22 experts to evaluate scientific evidence and make recommendations to control and prevent future pandemics, detailed in the report, which IPBES members will now consider whether to endorse. 

“The two biggest driving forces for pandemics are forest degradation and industrial animal production,” says Thomas Gillespie, an associate professor in Emory’s Department of Environmental Sciences and Rollins School of Public Health, who served as a scientific peer reviewer for the report. “Greater management and surveillance of wet markets, where live animals are sold, is also important.” 

Every major economic decision, Gillespie warns, needs to take into account what he calls “natural capital” in order to avoid even bigger catastrophes than the current pandemic. 

The economic costs of a major pandemic are 100 times the estimated costs of prevention, the report notes. It recommends government policy changes to reduce globalized agricultural expansion and the types of trade that have led to pandemics. Some of the possible measures it cites are taxing meat consumption and livestock production and reforming financial aid for land use to consider risks to biodiversity and health. 

Like all pandemics, the emergence of the novel coronavirus was driven entirely by human activities, the report states. The authors estimate that another 1.7 million currently “undiscovered” viruses exist in mammals and birds — and nearly half of them may have the potential to infect people. 

National governments need to incorporate a “One Health” approach — considering the deep connections between the health of people, domesticated animals, wildlife and ecosystems — to build pandemic control and prevention efforts, the report adds. 

Thomas Gillespie in 2018 with famed primatologist Jane Goodall. He is working with the Jane Goodall Institute on a One Health project in Tanzania's Gombe National Park.

Gillespie is a disease ecologist who helped pioneer the “One Health” approach to protect humans, ecosystems and biodiversity. His projects in Africa, including collaborating with Jane Goodall at Gombe National Park in Tanzania, are focused on helping farmers subsisting amid fragmented forests co-exist with primates and other wildlife in ways that minimize the risk of pathogen exchange between species, known as “spillover.” HIV, for instance, spilled over from chimpanzees to humans. Infectious disease and deforestation are the two biggest challenges facing chimpanzees at Gombe today, according to a newly published study led by Goodall and co-authored by Gillespie. 

The Gillespie Lab has a similar project in Costa Rica, focused on bats in fragmented natural ecosystems.

Now, Gillespie finds himself virtually managing his lab’s field projects while also advising global policymakers. “More people are listening,” Gillespie says. “This pandemic has fueled awareness that a One Health approach applied on a grand scale is vital to both local and global economies.” 

In the following Q&A, Gillespie explains the seismic shifts he says are needed to protect global health and economies against the impacts of pandemics. 

What do you mean exactly by “natural capital”? 

Natural capital consists of ecosystems of nature that sustain us. Human activity has driven an overall global decline in natural resources of 40 percent per capita in just over 20 years. Our economies, our health and our well-being are all built upon natural capital. 

There is growing recognition that we are totally dependent on the natural capital of our planet and that perpetual economic growth is not sustainable. We’ve had a false sense that we can simply measure the success of countries and policies through gross domestic product and economic growth, even when it means we are taking loans from nature that we have no capacity to repay. 

The rising risks of pandemics has caught the attention of people who are in charge of economies because COVID-19 is immediately affecting bottom lines. Every country is feeling the pain simultaneously, at both individual and national levels. 

Is it possible for human development and conservation to co-exist? 

When people talk about development from an economic standpoint it involves conversion of natural resources for profit, often by degradation of ecosystems via mining, timber cutting, oil extraction or clearing for cash crops. But when we talk about development from a sustainability perspective, we’re talking about improving the quality of human life. 

Use of the word “development” in these different ways can lead to a great deal of confusion. The urgency of the coronavirus pandemic is helping to break the silos down so that people from both camps can come together to think about solutions. There is growing recognition that instead of just considering whether a land-use project will impact a certain endangered species, we need to have mechanisms to evaluate more broadly how projects may impact the health of wildlife, people and an entire ecosystem. 

Right now, those profiting from economic development are not the ones paying the costs. The data shows very clearly that you can have a high GDP (gross domestic product) and also have plenty of poor people and a large proportion of a population struggling to survive. There is not a clear linkage between gains in the stock market and the quality of life for the average citizen. 

How does climate change fit into this “One Health” approach? 

Although many have rallied behind mitigating and adapting to climate change, it’s just one of the troubling vital signs of the planet. Climate change, biodiversity loss and the ever-increasing risks of pandemics are all symptoms of the same illness — our disconnect with nature and associated unsustainable norms. 

We’ve long needed to bring together climate scientists, disease ecologists and policymakers from agriculture, financial and environmental systems to tackle the illness instead of just having them all separately focus on individual symptoms. This shift is occurring, discussions are happening. The challenges are enormous, but at least now everyone has come together at the same table to try to work toward solutions. 

What are some examples of individual countries taking on these challenges? 

U.S. President-elect Joe Biden has vowed to rejoin the Paris Agreement for carbon reductions and set a 2050 carbon neutrality target. That holds huge implications for global climate diplomacy and will also create opportunities to rally behind shared solutions to prevent future pandemics and to safeguard the planet’s ecosystem services upon which our collective future depends. 

Some governments are beginning to remove environmentally harmful subsidies and redirecting incentives for a green recovery. In fact, New Zealand, Scotland and Iceland are recasting their entire economic frameworks to officially prioritize human well-being and planetary health over GDP. 

New Zealand developed a “Living Standards Framework” to set its budget. Bhutan now shapes policy to advance what it calls its “Gross Happiness Indicator.” Similarly, the world’s largest sovereign wealth fund — the Norwegian Government Pension Fund — has divested from 32 companies involved in unsustainable palm oil production. 

These kinds of initiatives are leading the way to build a better future together.

Bat ecology in the era of pandemics

Bats are primarily creatures of the night. Their cape-like wings, alien faces and strange behaviors drive human fascination and fear.

“People have so many misconceptions,” says Amanda Vicente, who studies the disease ecology of bats as an Emory University doctoral candidate. “Bats are associated with dark things, like Dracula. They have never had a good reputation.”

Evidence linking viruses carried by bats to disease outbreaks, from the ongoing COVID-19 pandemic to SARS, Marburg, MERS, Nipah, Hendra and Ebola, is not helping their image.

“It’s important for people to know that our enemies are not the bats, but the pathogens,” Vicente says. “And in order to better fight these pathogens, we need to understand their evolutionary relationship with bats, and how that relationship is being altered by human behaviors.”

Read more about the work of Vicente, who is leading a team of Emory students to study cave bats in her native Costa Rica.

Beware false 'cures' for COVID-19

Cinchona is toxic and self-medication with it or any other unproven "cures" should be avoided.

Following is an excerpt from an article in The Conversation, co-written by Cassandra Quave, an ethnobotanist at Emory University; Kim Walker, from the Royal Botanic Gardens, Kew; and Nataly Olivia A. Canales, from the Natural History Museum of Denmark. 

Chloroquine and hydroxychloroquine are [antimalaria drugs that are] currently being researched as potential treatments for COVID-19. …

False links are now being made [on social media networks] between another source of antimalarial compounds, cinchona bark, as a natural or alternative source of chloroquine or hydroxychloroquine. As quinine from cinchona bark is an ingredient in tonic water (in very low amounts), there have been rumors that it could also protect against SARS-CoV-2 – the virus that causes COVID-19.

Since its discovery in the 17th century, the bark of the Andean cinchona tree and its chemical constituents, known as quinoline alkaloids (quinine, quinidine, cinchonine and cinchonidine), provided the only treatment for malaria for over 300 years. In 1934, scientists developed the first synthetic antimalarial, later known as chloroquine. Although chloroquine was inspired by the antimalarial activity of quinine, its chemical structure (and pharmacological properties) are quite different from the natural compounds found in cinchona bark.

To date, there is no laboratory or clinical evidence that quinine or any other cinchona bark compounds exhibit activity against COVID-19. Also, not everything that is natural is safe. Cinchona and quinine are toxic and can cause serious side-effects known as “cinchonism” which can include hearing and vision loss, breathing issues, and heart and kidney issues. It can also lead to a coma.

While quinine pills were once sold over the counter in the US to treat night leg cramps, they were pulled from the market by the Food and Drug Administration in 2006 after serious side effects and death were reported.

History is full of examples of people profiting from the public’s panic and fear during unstable times. The European Union law enforcement agency has already seized 48,000 packages of potentially dangerous pharmaceuticals, including unauthorized chloroquine, as well as fake masks and bogus coronavirus cures.

The benefits, if any, of chloroquine or hydroxychloroquine for treating COVID-19 are still not fully understood. Cinchona bark does not contain either of these compounds, and the alkaloids in the bark bear no relation to them. Likewise, there is no evidence of cinchona being able to prevent or treat COVID-19.

Cinchona is highly toxic and self-medication with it or any other unproven cures should be avoided. Protect your health and don’t waste money funding unethical people and companies profiteering off fear in these uncertain times.

Great apes and COVID-19: Experts raise the alarm for endangered species

A mountain gorilla in the wild. Endangered great apes are susceptible to human respiratory diseases, warns Emory disease ecologist Thomas Gillespie.

By Carol Clark

Primate experts warn that the global human health emergency of COVID-19 also threatens our closest living relatives — endangered great apes.

Nature published their commentary raising the alarm that non-human great apes are susceptible to human respiratory diseases. The 25 authors call for urgent discussions on the need to severely limit human interaction with great apes in the wild, and in sanctuaries and zoos, until the risk of COVID-19 subsides.

“The COVID-19 pandemic is a critical situation for humans, our health and our economies,” says Thomas Gillespie, a disease ecologist at Emory University, and a lead author of the commentary. “It’s also a potentially dire situation for great apes. There is a lot at stake for those in danger of extinction.”

Some countries have already suspended great ape tourism, and others with ape tourism and field research need to seriously consider following suit, the authors write. They add that the same applies to sanctuaries and zoos where great apes and humans are in closer contact.

While great ape tourism will inevitably plummet due to the pandemic, all it takes is one infected visitor to spark catastrophe, the experts warn.

The non-human great apes include chimpanzees, bonobos and gorillas, which live in parts of Sub-Saharan Africa, and orangutans, which are native to the rainforests of Indonesia and Malaysia. The International Union for Conservation of Nature (IUCN) lists chimpanzees and bonobos as endangered species, while gorillas and orangutans are critically endangered.

Habitat loss, poaching and disease are the primary threats to the remaining great apes.

Even exposure to viruses that have mild effects in people, such as those causing the common cold, have been associated with mortality events in wild primates. Because the coronavirus that causes COVID-19 is fatal for some humans, experts fear it could potentially prove devastating to great apes. Evidence suggests COVID-19 may be transmitted by people who have only mild symptoms, and perhaps even those who are asymptomatic.

“People who are younger, who may be less at risk for severe illness from COVID-19, are the ones who are more apt to be hiking into the national parks of Africa and Asia to see great apes in the wild,” Gillespie says. “It would be extremely difficult to monitor whether they were infected with COVID-19 since they may not have obvious symptoms.”

Great ape tourism has contributed to conservation in many positive ways, providing an economic incentive for governments and individuals to support their protection. Donors are needed to help shore up marginal economies facing the loss of tourism dollars and to continue to protect the health of people and the great apes in the wild, Gillespie says.

Tourism has habituated wild great apes to not fear humans, he adds. Without staff to patrol and protect them, the animals would become even more vulnerable to poachers.

“Essential staff needs to remain in place,” Gillespie says. “But we need to make sure that staff numbers are low and that they are engaged in proper processes to protect themselves, and the apes, from exposure to COVID-19.”

Gillespie studies how germs jump between wild animals, domesticated animals and people. Through this “One Health” approach, he aims to protect humans, ecosystems and biodiversity. As a member of the IUCN, Gillespie helped develop the organization’s “Best Practice Guidelines for Health Monitoring and Disease Control in Great Ape Populations.” In 2017, Gillespie co-authored a landmark report detailing that 60 percent of the more than 500 primate species worldwide are threatened with extinction, while 75 percent have declining populations.

Fabian Leendertz, from the Robert Koch-Institute, Germany, is co-lead author of the Nature commentary. Additional authors include experts involved in primate research, conservation and policymaking from around the world.

“As professionals working with great apes,” the authors conclude, “we bear a responsibility to protect them from our pathogens. We hope for the best but should prepare for the worst and critically consider the impact of our activities on these endangered species.”

Emory soil analysis project leads to EPA site investigation

An Emory University collaboration with members of Atlanta’s Westside community, to test urban soil for contaminants, has led to a site investigation by the U.S. Environmental Protection Agency (EPA). The ongoing community collaboration is funded by Emory’s HERCULES Exposome Research Center, dedicated to understanding how environmental exposures affect health and community well-being.

The EPA told the Atlanta Journal-Constitution that it is continuing to collect samples and has so far identified 64 sites where the soil contains elevated levels of lead — a dangerous neurotoxin. The agency plans to begin decontaminating properties, possibly by removing and replacing soil, in the first quarter of next year, at no expense to residents or homeowners, according to the AJC. The report also appeared in Georgia Health News.

“It’s important for people to know that soil contamination by heavy metals can be serious,” says Eri Saikawa, an associate professor of environmental sciences at Emory and the lead researcher on the original project that sparked the EPA investigation. “If you are thinking about gardening in an urban area, or if children are playing in your yard, it makes sense to test your soil and make sure that it’s not contaminated.”

Artificial intelligence and 'deep ethics'

In the sci-fi film “2001: A Space Odyssey,” astronauts go into a soundproof pod to discuss their concerns about some of the decisions made by the supercomputer Hal (seen through the window) without realizing that Hal knows how to lip read.

Advances in neurotechnology, genetics and artificial intelligence are not only going to change society as a whole, they are actually going to challenge what it means to be human and change our ethics, argues Paul Root Wolpe, director of the Emory Center for Ethics, in a recent TEDx Atlanta talk.

He uses self-driving cars as just one example.

“These vehicles are going to be going down the road and in a crisis they’re going to have to make decisions about what to do,” Wolpe says. “Do I crash into the wall and endanger my passengers or do I turn left and hit those pedestrians? For the first time we’re going to have to create ethical algorithms. That is, we’re going to have to teach a vehicle to make ethical decisions. For the first time, machines will be making ethical decisions that will have a profound impact on human beings.” 

Watch Wolpe’s talk in the video below to learn what he means by the term “deep ethics,” and how artificial intelligence may someday help us navigate through the ethical complexities raised by technology itself.

Growing knowledge and healthy food

From Emory Magazine

As an undergraduate biology major at Clemson University, Daniel Parson recognized the disconnect between environmental sustainability and traditional agriculture. He went on to get a masters degree in plant and environmental science from Clemson and spent more than a dozen years working in organic farming in Georgia and South Carolina.

"We look at nature as wilderness, but we also need things from nature and we need to learn how to get them without destroying it," says Parson.

He joined Emory's Oxford campus in 2014 to run the Oxford Organic Farm, an 11-acre piece of land that provides produce for the university's dining halls and farmers markets and unique learning opportunities for students.

"We try to match the seasons with when students are on campus so our work-student students who are here every day have the best experience possible and so we can work with faculty to connect course curriculum to the farm," says Parson, whose official title is farmer-educator. "For economics classes I might talk about how we set prices and interact with markets, but for other classes I may just be talking about the experiences I've had and how that connects with what they are discussing in class."

Frankenstein at 200 sparks wonder and debate

Emory's Stuart A. Rose Manuscript, Archives and Rare Book Library holds an 1881 original edition of "Frankenstein" and an 1831 edition, above, with a depiction of the "creature" and a prologue by Mary Shelley.

It’s the 200th anniversary year of “Frankenstein, Or the Modern Prometheus,” an enduring novel at the nexus of major questions of our time. Emory faculty explore many of them in a newly published anthology, “Frankenstein: How a Monster Became an Icon, the Science and Enduring Allure of Mary Shelley’s Creation.”

“When you see a contemporary film about androids, like ‘Blade Runner 2049,’ you’re seeing the ‘Frankenstein’ story in a 21st-century guise,” says Sidney Perkowitz, Emory emeritus physicist and co-editor of the new anthology. “The androids are sleek and modern instead of the shambling, stitched-together creature in ‘Frankenstein,’ but they have the same questions swirling around them. Even as we’re on the verge of artificially generating life, we’re no closer to knowing whether we should.”

Ecosystems hanging by a thread

Emory disease ecologist Thomas Gillespie served on an international committee that developed best practice guidelines for health monitoring and disease control in great ape populations, part of a growing public education effort.

By Tony Rehagen
Emory Magazine

Thomas Gillespie’s parents and teachers always wanted him to go into medicine.

“Growing up in Rockford, Illinois, if you were smart and interested in biology, you were supposed to be a doctor,” he says.

Gillespie, meanwhile, was always more interested in primates. In seventh grade, he phoned animal psychologist Penny Patterson, famous for teaching the gorilla Koko how to use sign language, and interviewed the scientist about Koko’s diet while punching out notes on a typewriter. He was premed at the University of Illinois, but spent his internship at the Brookfield Zoo in Chicago, working in the “Tropic World” primate exhibit. His favorite undergrad course was biological anthropology, the study of biological and behavioral aspects of humans and nonhuman primates, looking at our closest relatives to better understand ourselves.

Gillespie eventually took a year off before graduate school to work with primate communities in the Peruvian Amazon. The apes finally won out — Gillespie would choose a doctorate in zoology over medical school.

But it wasn’t long before the two fields of study collided. While monitoring the group behavior of colobine monkeys in Africa, Gillespie observed that some of the animals were eating bark from the African cherry tree — not a typical food source for them. When he dug deeper, Gillespie learned that human doctors in the region used that same bark to treat parasites in their patients. The monkeys, he realized, were self-medicating.

“That discovery in these monkeys brought me back toward the health science side of biology,” says Gillespie.

Gillespie’s return to a medical approach to zoology came not a moment too soon—for the sake of the primates and maybe even all of humankind. As an associate professor in Emory’s Department of Environmental Sciences specializing in the disease ecology of primates, Gillespie and his team of researchers have helped uncover a crisis among our nearest taxonomic neighbors. According to an article coauthored by Gillespie and thirty other experts and published in the journal Science Advances, 75 percent of the world’s five-hundred-plus primate species are declining in population, and a whopping 60 percent face extinction, largely due to human encroachment.

The Lying Conference: Uncovering truths about deception

The Lying Conference will unmask the many factors involved in deception, including evolution, culture and the human affinity for storytelling and make believe.

By Carol Clark

We grow up with this notion that we should always tell the truth. But can we live without lying? 

That’s one of the questions to be explored in a day-long event, “The Lying Conference,” on Friday, November 17, from 8:30 am to 6:30 pm at Emory Conference Center. Emory’s Department of Psychology is bringing together scientists from psychology, neuroscience and anthropology — along with a leading journalist, a theater director and a professional magician — to discuss their insights into lying and deception. The conference is free and open to the public, but registration is requested. 

Topics to be covered include: The deep, evolutionary roots of lying. How children learn to tell lies. Cultural differences in lying. How we decide whether someone is trustworthy. How technology and the changing media and political landscapes are affecting our collective beliefs. The role of deception in the arts and entertainment.

“Lying is kind of a hot topic right now, with all the buzz about fake news and accusations of cover-ups and deception,” says Emory developmental psychologist Philippe Rochat, lead organizer of the event. “When we talk about lying, what we are indirectly trying to understand is, what is the truth? It can be a profound question.”

Science uses probabilities to approximate the truth, Rochat notes. “It’s a never-ending journey and you keep trying to get closer.”

In day-to-day interactions, we regularly negotiate the truth with one another, trying to convince others of a point of view. “People put on makeup to exaggerate their features,” Rochat says. “We amplify some things about ourselves and hide others. We make believe. We seduce.”

People can lie maliciously, in an anti-social way. Or they can tell white lies, to be polite and avoid hurting another person’s feelings.

Rochat is particularly interested in the developmental trajectory of lying. Between the ages of two and three, children begin to engage in pretend play. By around age four, when children start to have ideas about what other people are thinking, lying emerges. “They can be explicit at this stage, because they can understand that someone can be deceived,” Rochat says. “But they still cannot lie very well. They tend to leak the truth.” By the age of six or seven, he adds, “we become much better at concealing the truth and keeping a secret tight.”

Whatever the reasons for lying, one thing is clear: “We’ve evolved to lie,” Rochat says. “It’s deeply rooted in our nature and somehow important to our survival.”

Following are the seven speakers of the conference and brief summaries of their topics.

“Perspective-taking and Dishonest Communication in Primates and Other Animals,” by Emory primatologist Frans de Waal: While there is plenty of evidence for functional deception in animals — such as the way a butterfly might use mimicry as camouflage — but tactical deception requires anticipating the reaction of others. Tactical deception is clearly more developed in apes than most other species, although there is also evidence for corvids.

“Lying, American Style,” by Emory anthropologist Bradd Shore: He will discuss the role of culture in lying and how it differs across cultures. Shore will also touch on the some of the ways the American cultural model has been politically deployed and manipulated in recent decades.

“Little Liars — How Children Learn to Tell Lies,” by Kang Lee a developmental psychologist from the University of Toronto: Lee will use scientific evidence from his lab to show how lying begins early in life, what factors contribute to the development of lying, why children lie and whether adults can easily detect children’s lies. He will also discuss recent developments in technology that may help in detecting lies.

“Face Value — The Irresistible (and Misleading) Influence of First Impressions,” by neuroscientist Alexander Todorov from Princeton University: People form instantaneous impressions from faces and act on these impressions. In the last 10 years, data-driven computational methods allow scientists to visualize the configurations of face features leading to specific impressions such as trustworthiness. But these appearance stereotypes are not often accurate. So why do we form first impressions?

“What Happened to the News? Technology, Politics and the Vanishing Truth,” by Johnathan Mann, former CNN International anchor: Many American believe that the news media intentionally lie to them. President Donald Trump is the best-known detractor of “fake news,” though he himself has been accused of lying more than any other public figure in recent memory. Mann will address the overlapping changes to technology, politics and business that have crippled our national conversation with deception and distrust.

“Onions and Identities — Theater and the True Self,” by Emory dramatist Tim McDonough: Drama is densely populated by duplicitous schemers, by power figures whose lies maintain the sociopolitical status quo, and by characters in search of themselves, who mirror to us our confusions and self-deceptions. Theater provides a template for understanding identity and insight into existentially and socially necessary forms of deceit.

“The Science of Magic and the Art of Deception,” by professional magician Alex Stone: Magicians trick our brains into seeing what isn’t real, and for whatever reason our brains let them get away with it. Through a mix of psychology, storytelling and sleight-of-hand, Stone will explore the cognitive underpinnings of misdirection, illusion, scams and secrecy, pulling back the curtain on the many curious and powerful ways our brains deceive us not just when we’re watching a magician but throughout our everyday lives.

Responding to climate change


By Martha McKenzie
Emory Public Health

Climate change. Partisan politicians debate its reality, and many citizens see it as a faraway threat, something that endangers the future of polar bears but not them personally.

The health effects of global warming, however, are already being felt. Extreme weather events such as wildfires, droughts, and flooding are becoming more frequent, resulting in more injuries, deaths, and relocations. Heat and air pollution are sending people with asthma and other respiratory ailments to the emergency room. Diseases carried by mosquitoes, fleas, and ticks are expanding their territory—dengue has become endemic in Florida, Lyme disease has worked its way up to Canada and over to California, and some fear that malaria may re-emerge in the U.S.

Tie these health burdens—which are only likely to worsen—with the current administration’s decision to pull out of the Paris climate agreement and dismantle environmental regulations, and the call to action becomes more urgent. “The federal government’s actions might be a headwind from a funding perspective, but they are also very much a tailwind from an inspiration and motivation perspective,” says Daniel Rochberg, an instructor in environmental health who worked for the U.S. State Department as special assistant to the lead U.S. climate negotiators under presidents Bush and Obama. “As others have said, ‘We are the first generation to feel the sting of climate change, and we are the last generation that can do something about it.’ We have to get busy doing something about it.”

Rollins School of Public Health has gotten busy. Faculty researchers are building the science of climate impacts, strategies for reducing greenhouse gas emissions, and approaches for increasing resilience to climate change. Climate@Emory, a university-wide organization of concerned students, faculty, and staff, is partnering with other academic institutions, industries, and governments to support education and climate remediation efforts. Through Climate@Emory’s initiative, Emory University is an accredited, official observer to the UN climate talks and has sent students and faculty to the climate conferences in Paris in 2015 and in Marrakech in 2016. And, of course, Rollins is educating the next generation of scientists who will be dealing with the fallout of today’s climate decisions.

“For environmental scientists, it’s a challenging climate,” says Paige Tolbert, O.

Unveiling of Frankenstein portrait to set stage for year-long celebration of the classic novel


A public unveiling and discussion of a large-scale portrait of Dr. Frankenstein’s creation, described in Mary Shelley’s 1818 novel “Frankenstein," will take place at 7 pm at Emory on Tuesday, September 19. The event will be held at the Schwartz Center for the Performing Arts and is open to all free of charge, but guests must register in advance at http://engage.emory.edu/Frankenstein or call Erin Mosley at 404-727-5048.

The portrait is by renowned artist Ross Rossin, who is on the Emory campus as the 2017-2018 Donna and Marvin Schwartz Artist-in-Residence. Rossin, whose art hangs in the Smithsonian National Portrait Gallery and was exhibited at the United Nations Palace of Nations in Geneva and the Russian Duma in Moscow, is also known to Atlantans as the sculptor/creator of the nine-foot-tall bronze statue of Hank Aaron unveiled earlier this year at SunTrust Park.

Rossin's residency is part of the Ethics and the Arts Program at Emory's Center for Ethics. The program, the only one of its kind in the nation, encourages ethical discourse and debate through and about the arts, and partners with arts organizations to demonstrate the way art challenges ethical perspectives.

This year, the residency coincides with FACE (Frankenstein Anniversary Celebration and Emory), a year-long university-wide celebration of the 200th anniversary of the novel.

The exclusive corporate sponsor of FACE is Turner Classic Movies (TCM), and Emory is providing support through its Science and Society fund.

“One of the most acclaimed and influential works of science fiction ever written, ‘Frankenstein’ continues to shape debates surrounding science and its complications,” says Paul Root Wolpe, director of Emory’s Center for Ethics, which is spearheading FACE. “It’s a permanent part of the dialogue about the dilemmas we face in technological advancement, scientific experimentation and research, bioethics, artificial intelligence, stem cell research and innovation.”

Rossin’s new depiction of Frankenstein’s creation is expected to highlight the broad influence and implications of the landmark novel. Rossin envisioned not the standard movie portrayal, but a portrait based on his vision of Shelley’s intent.

“It’s precisely Mary Shelley’s youth [age 18 when she began the novel] that inspired me to approach my subject differently,” says Rossin. “Unlike all other portrayals before, I prefer to see the Creature as a young man.”

As Rossin points out, Dr. Frankenstein intended “to create something beautiful, young, powerful and promising, like Prometheus. The Creature was supposed to have a future, open a new chapter in human history.”

Those familiar with the story know that Dr. Frankenstein’s good intentions turned ugly and murderous. Rossin says that his portrait of “Adam Frankenstein reflects exactly this kind of tragic duality. In my work the viewer should be able to see both.”

Georgia Climate Project creates state 'climate research roadmap'

Emory Report

Scientists, researchers and environmental experts from across the state convened at Emory last week to draft the “Georgia Climate Research Roadmap” — a set of targeted research questions that could help Georgia better understand and address one of the century’s defining challenges.

The goal of the May 22-23 gathering was to formulate “Georgia’s Top 40,” key climate research questions that could eventually aid decision-making and planning for Georgia policymakers, scientists, communities and service organizations.

An initiative of the Georgia Climate Project, the roadmap was a response to the fact that communities across Georgia are already exploring strategies to address the impact of climate change, says Daniel Rochberg, chief strategy officer for the Climate@Emory initiative and an instructor in the Rollins School of Public Health and Emory College of Arts and Sciences, where he focuses on climate change and sustainable development.

Some Georgia communities are actively assessing vulnerabilities and strategies to build resilience to potential climate change impact, while others are developing technologies and policies to begin reducing emissions, according to Rochberg, who has also worked for the U.S. State Department as special assistant to the lead U.S. climate negotiators under presidents Bush and Obama.

“To inform this work, decision-makers at all levels need credible and relevant information from across the natural, applied and social sciences,” says Murray Rudd, an associate professor in Emory’s Department of Environmental Sciences and member of the climate research roadmap steering committee. “The Georgia Climate Research Roadmap seeks to fulfill this need by identifying the key research questions that, if answered, can lay the groundwork for the state and its residents to take effective, science-based climate action,” he says.

Small world, big impact: The Emory Global Health Institute

The Emory Global Health Institute helped fund a program in Haiti for those suffering from depression in communities ravaged by natural disaster and conflict. This photo, near the town of Hinche, was taken by Emory medical student Jesse Rappaport, one of the 2016 winners of the EGHI Global Health Student Photography Contest.

By Sylvia Wrobel
Emory Magazine 

The little boy died at home, without medical attention, before his fifth birthday. It happens to as many as one in five children in poor African and South Asian countries. The boy was deeply mourned, but never counted. His death was not noted in any registry. Except for a fever, no one had any idea why he died—information that might have been lifesaving for family members, or helped health officials recognize and address a widespread problem, or been the earliest indication of a smoldering epidemic.

In 2015, when the Bill and Melinda Gates Foundation wanted to learn why so many die young, they turned to the Emory Global Health Institute (EGHI) to lead the Child Health and Mortality Prevention and Surveillance Network (CHAMPS), designed to help high-child-mortality countries strengthen their capability to collect, analyze, interpret, and share data. Innovative methods include training local teams to visit families soon after a child dies,gathering information on symptoms and, with permission, taking small needle tissue biopsies, which when examined with specialized tools developed at the US Centers for Disease Control and Prevention (CDC) can identify the specific organisms causing illness and death.

“While we would think we have a pretty good idea of why children are dying—respiratory disease, enteric infections, fevers, and sepsis from different microorganisms—we don’t know those specific causes,” says Jeffrey Koplan, former director of the CDC and now Emory Vice President for Global Health and EGHI’s founding director. “There are a lot of different things that can cause respiratory failure. A lot of illnesses can lead to gastroenteritis and then death. The objective of this grant is to identify the specific causes of death so that we can develop programs to address them and save lives.”

CHAMPS is big: A $75 million investment for the first three years of a projected 20-year study, involving hundreds of partners at field sites and programmatic support from Emory, the CDC, and other Atlanta-based and international partners. But EGHI was created to serve as the mainframe for just such large-scale, long-term efforts—whether addressing high rates of maternal and childhood morbidity, understanding the spike of diabetes in developing nations, or increasing access to safe water.

Borders don’t mean much to infectious diseases, from shape-shifters like HIV and drug-resistant tuberculosis to sudden outbreaks like Ebola, SARS, or Zika. Chronic problems like diabetes and cardiovascular disease no longer belong primarily to richer, fatter nations but take an increasingly heavy toll on the economic stability, development, and even national security of developing nations, all with global impact.

Founded 10 years ago as the flagship program to expand Emory’s commitment to global health, EGHI is its own entity, university-wide, not part of any individual school. The organization is deliberately compact—a staff of ten, a cluster of offices, no big signs on the door. But its design—pragmatic, strategic, multidisciplinary, partner focused—gives it maximum flexibility in how to identify and tackle problems.

The top 10 policies needed now to protect pollinators

Bee thankful: “If you enjoyed a bountiful Thanksgiving Day dinner, you should give thanks to pollinators,” says Emory biologist Berry Brosi.

By Carol Clark

Scientific experts from eight different countries developed a list of the top 10 policies needed to reverse the decline of pollinators crucial to the world’s food supply.

The journal Science is publishing the recommendations for the global community in a forum article, “10 Policies for Pollinators.” The recommendations will be presented at the United Nations Convention of the Parties on Biological Diversity (CoP13), to take place in Mexico December 4 to 17.

“If you enjoyed a bountiful Thanksgiving Day dinner, you should give thanks to pollinators,” says Berry Brosi, a biologist and ecologist in Emory University’s Department of Environmental Sciences and a co-author of the article.

Brosi cites the first policy recommendation on the list as the most concrete and actionable: Better pesticide regulatory standards.

He adds that several of the recommendations related to sustainable agriculture more broadly include making chemical control for insects and other pests a last resort.

“Especially in light of the emergence of the Zika virus, and widespread public concern about mosquito-borne diseases, we are likely to see increased demands for pesticide use,” Brosi says. “Mosquito control is, of course, important, but we also need to be thoughtful about what kinds of pesticides we use and how we use them. We should carefully consider the impact on pollinators and other biodiversity.”

The Environmental Protection Agency is currently reviewing a class of insecticides commonly used in agriculture, neonicotinoids, which have been linked to wide-scale bee declines and impacts to other pollinator species by a range of scientific studies.

"Neonicotinoids are known to kill bees and other insect pollinators in very low doses, and to cause behavioral disruptions in even minute concentrations, measured in parts-per-billion," says Brosi, whose research focuses on both managed honeybees and wild bees.

In 2014, Emory began taking steps to eliminate the use of neonicotinoid-based pesticides and pre-treated plants on its campus grounds, the first university to do so worldwide.

The EPA’s review of the safety of neonicotinoids is not due until 2017.

The complete list of recommended policies for pollinators is as follows:

1. Raise pesticide regulatory standards
2. Promote integrated pest management
3. Include indirect and sublethal effects in GM crop risk assessments
4. Regulate movement of managed pollinators
5. Develop insurance schemes to help farmers
6. Recognize pollination as agricultural input in extension services
7. Support diversified farming systems
8. Conserve and restore “green infrastructure” (a network of habitats that pollinators can move between) in agricultural and urban landscapes
9. Develop long-term monitoring of pollinators and pollination
10. Fund participatory research on improving yields in organic, diversified and ecologically intensified farming

The policy recommendations follow a United Nations warning in February that pollinators were under threat. Brosi was among 77 international experts who worked on that report, the first global pollinator assessment for the U.N.’s Intergovernmental Panel for Biodiversity Ecosystem Services (IPBES).

The assessment found that more than 40 percent of invertebrate pollinator species, particularly bees and butterflies, face extinction. And 16 percent of vertebrate pollinators are under threat. The issue is critical to agricultural, economics and the health of humans and ecosystems: 75 percent of the world’s food crops depend on pollination by at least one of 20,000 species of pollinators, including bees, butterflies, moths, wasps, beetles, birds, bats and other vertebrates.

Why Zika risk is low for Olympic athletes in Rio

An aerial view of Rio de Janeiro, host of the 2016 Summer Olympics. "August is the winter season in Rio, when mosquito populations are at their lowest," says Emory disease ecologist Uriel Kitron.

By Carol Clark

Some health professionals have lobbied to postpone the upcoming Rio de Janeiro Olympics due to the risk of the Zika virus, which is spread by mosquitos and – less commonly – through sexual intercourse. Other experts disagree that Zika poses a significant enough threat to warrant changing the venue or date of the games, set for August 5 to August 21.

“The risk of Zika infection in Rio during the Olympics is very low,” says Uriel Kitron, chair of Emory’s Department of Environmental Sciences and an expert on mosquito-borne diseases. “But if you are pregnant, or are thinking of getting pregnant right now as part of a couple, then you may want to consider even this low risk of transmission, given the potential serious complications.”

He refers travelers to the current advisory of the Centers for Disease Control and Prevention. The CDC advises women who are pregnant “to consider not going to the Olympics,” due to the link between Zika infections and severe birth defects. The CDC also recommends special precautions for men and women to practice safe sex following any possible exposure to the Zika virus.

When Zika popped up in Brazil last year, Kitron already had ongoing research projects in the country focused on how urban mosquitos spread the viruses of dengue and chikungunga. The population had no immunity to Zika and the virus swept like wildfire through the country. Kitron and his Brazilian colleagues quickly expanded their research to include cases of Zika, which can cause a rash and relatively mild illness, although most of those infected have no symptoms at all. It was not until months later that the more insidious effects of the Zika virus became apparent.

Kitron and his colleagues completed one of the first epidemiological studies, now out in Emerging Infectious Diseases, showing the strong link between the epidemic curve of the outbreak and a spike in cases of Guillain-Barré syndrome and babies born with smaller than normal heads, a condition known as microcephaly.

In the following interview, Kitron discusses some of what is now known about this emerging infectious disease and why mosquito surveillance and control is currently the key to containing its spread.

Why do you think the risk is low for Zika virus transmission during the Olympics?

For one thing, August is the winter season in Rio, when mosquito populations are at their lowest. And the areas where the athletes will be staying and competing are well-maintained, making Olympic visitors even less likely to encounter a mosquito.

The rates of Zika infection in Brazil have gone down drastically since last year, probably because the population now has herd immunity, so that further lowers the risk of transmission. Brazil is no longer the “hot spot” of the Zika pandemic. The horse has already left the barn as Zika has moved throughout Latin America and the Caribbean.

The U.S. territory of Puerto Rico, where an outbreak began more recently, currently has high rates of new Zika infections and summer is the high season for transmission.

The Nilton Santos stadium in Rio, one of several Olympic venues.

What is the risk of contracting Zika virus from a mosquito in the United States? 

Unless you are in the U.S. territories of American Samoa, Puerto Rico or the U.S. Virgin Islands, the risk is very low for most of the United States and will likely remain very low.

In the past, we have seen a few cases of locally transmitted dengue fever and chikungunya in South Texas and South Florida. The Aedes aegypti mosquito, the main vector of dengue, chikungunya and Zika, can be found in states bordering the Gulf of Mexico. The much more widespread Aedes albopictus, better known as the Asian tiger mosquito, has also shown that it can transmit these diseases, at least in a laboratory setting. Aedes albopictus, however, is not as effective as a vector.

We’ve greatly reduced the density of Aedes aegypti in most of the country. It feeds almost exclusively on humans, prefers a tropical climate and particularly thrives in dense neighborhoods with substandard housing. People in warmer areas of the United States generally have window screens and air-conditioning.

While we could see limited transmission of Zika virus from mosquitos in the Gulf states, it would be unlikely to develop into intensive transmission. We have relatively better methods of disease surveillance and mosquito control in the United States, which is one reason why we haven’t had a major outbreak of dengue fever. So far, we have been able to catch cases early and control the spread.

Is the Zika virus a disease of the poor? 

Mosquitos bite everybody so it’s not only the poor who are affected by diseases like dengue and Zika. But, of course, there are more mosquitos in poorer areas and less protection from them. So the poor are generally at much higher risk.

What are the prospects for effectively combating the Zika virus globally? 

I’m optimistic that we will have a vaccine for Zika within a few years because there is only one strain of the virus, unlike the dengue virus, which has many different strains.

People have proposed releasing genetically modified, sterile male Aedes aegypti mosquitos. The idea is they would compete with the wild sterile males to reduce populations of disease-carrying mosquitos. Genetically modified mosquitos might be one tool to fight mosquito-borne diseases, but I’m skeptical whether they would compete that well with other mosquitos in natural conditions. The jury is still out on that question.

For now, good mosquito surveillance and larvae control remain the keys to prevent and contain outbreaks. It’s generally much easier to control mosquitoes at the larval stage by eliminating breeding sites.

A study led by the Emory Vaccine Center recently found that people infected with dengue virus develop antibodies that cross-react with Zika virus. Can you talk about how that relates to your ongoing epidemiological research in Brazil? 

I’m part of a collaboration with Brazilian scientists focused in Salvador, the capital of the Brazilian state of Bahia in the northeast region of the country.

We are continuing to study the epidemiology and ecology of the Zika, chikungunya and dengue viruses. We’re particularly interested in the co-circulation of the three. What does it mean to have several arboviruses circulating among a population as far as the complications in humans? For instance, during the Zika outbreak last year in Bahia, we think there was more chikungunya circulating than was previously realized. And it’s possible that the spike in Guillian-Barré cases may be more related to chikungunya.

It’s important to gather data on the interactions of people, pathogens and disease vectors like mosquitos. Not only could it help us combat current outbreaks, the data may help us deal with the next emerging infectious disease.

Zika virus raises issues of both abortion rights and disability rights

Women in 2015 protest a bill in North Carolina to increase restrictions for women seeking abortions.

Chloe Angyal writes in the Huffington Post about how the Zika virus may put abortion rights and disability rights on a collision course (although the causal connection between Zika and birth defects has not been established). Below is an excerpt from the article:

"While abortion rights advocates might well point to Zika-linked microcephaly as evidence that the U.S. needs to liberalize abortion laws, disability rights advocates might argue otherwise. On the issue of abortion, the feminist and disability rights movement often come into uncomfortable conflict as they struggle to accommodate both the rights of a woman to control her own fertility and the rights of people with disabilities to exist.

"Now, with the threat of Zika-linked fetal abnormalities looming, that fault line could well crack open, and at least one thought leader in disability rights is concerned by the hastiness with which calls for loosened abortion restrictions are being made.

"There are clear parallels between the experiences of women and those of people with disabilities (not to mention overlaps between the two groups), noted Rosemarie Garland-Thomson, a professor of English at Emory University and a pioneer of the discipline of disability studies. Through much of history, she said, able-bodied women were not allowed to control their own reproduction.

“'There’s a long, deep and troubling history of women’s reproduction being taken over by men and by a variety of other cultural institutions,' she told HuffPost. Likewise, people with disabilities have long been subject to reproductive coercion, from the abandonment of newborns with disabilities to mandatory sterilization of women with disabilities. They have, said Garland-Thomson, 'been eugenically eliminated from the world through selective abortion and other biomedical practices.' 

"Both groups have similar histories of subjugation, particularly around medical decision-making. And on the issue of access to abortion, particularly in the age of prenatal fetal testing, those histories collide."

Reporting from Paris: Student updates on COP21

Among the 10 undergraduates representing Emory at COP21 are, from left: Savannah Miller, Naomi Maisel, Taylor McNair, Mae Bowen and Siyue Zong.

“In a basement auditorium in a quiet Parisian neighborhood, writer Naomi Klein held an event to talk about the ‘Leap Manifesto: A Call for a Canada Based on Caring for the Earth and One Another,’” reports Emory junior Clara Perez from the scene.

“Climate change, Klein said, is the catalyst to transformative change in all kinds of struggles – indigenous, class, anti-racism, among many others. She called for addressing climate change in a way that is ‘based on justice and redressing historical wrongs.’”

Now midway through a two-week trip to Paris, a delegation of Emory undergraduates are providing real-time updates on the 21st Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change (COP21) and related events.

On the web site they’ve created, the students have posted photos of a demonstration that happened shortly after they landed in Paris. And they are gathering “snapshot” bios of other attendees, under the heading “Humans of COP21.”

Senior Taylor McNair writes: “From a business perspective, carbon pricing at COP21 is arguably the most exciting news to emerge from the first few days of the conference.”

Senior Mae Bowen was intrigued by an event at the Kedge Business School in Paris. Jean-Christophe Carteron presented a Sustainability Literacy Test he developed as a tool for universities and corporations to assess and develop the knowledge of their community members.

“While ‘sustainability’ is still a complicated term,” Bowen writes, “the goals of the Sustainability Literacy Test are admirable and a step in the right direction. No business or government leader should be able to claim ignorance when making decisions that negatively affect the future of our planet and humanity.”

Watch the web site for daily updates and follow the students’ updates on Twitter: @EmoryinParis.

And check out the podcasts that the students created as part of the Emory course “Paris is an Explanation: Understanding Climate Change at the 2015 United Nations Meeting in France.”
