Geosciences’ Shuhai Xiao finds fossils dating back 550 million years, among earliest known displays of animal mobility

[vc_row][vc_column][vc_column_text]

VT NEWS | September 4, 2019

In a remarkable evolutionary discovery, a team of scientists co-led by a Virginia Tech geoscientist has discovered what could be among the first trails made by animals on the surface of the Earth roughly a half-billion years ago.

Shuhai Xiao, a professor of geosciences with the Virginia Tech College of Science, calls the unearthed fossils, including the bodies and trails left by an ancient animal species, the most convincing sign of ancient animal mobility, dating back about 550 million years. Named Yilingia spiciformis – that translates to spiky Yiling bug, Yiling being the Chinese city near the discovery site – the animal was found in multiple layers of rock by Xiao and Zhe Chen, Chuanming Zhou, and Xunlai Yuan from the Chinese Academy of Sciences’ Nanjing Institute of Geology and Palaeontology.

The findings are published in the latest issue of Nature. The trials are from the same rock unit and are roughly the same age as bug-like footprints found by Xiao and his team in a series of digs from 2013 to 2018 in the Yangtze Gorges area of southern China, and date back to the Ediacaran Period, well before the age of dinosaurs or even the Pangea supercontinent. What sets this find apart: The preserved fossil of the animal that made the trail versus the unknowable guesswork where the body has not been preserved.

Shuhai Xiao

“This discovery shows that segmented and mobile animals evolved by 550 million years ago,” Xiao said. “Mobility made it possible for animals to make an unmistakable footprint on Earth, both literally and metaphorically. Those are the kind of features you find in a group of animals called bilaterans. This group includes us humans and most animals. Animals and particularly humans are movers and shakers on Earth. Their ability to shape the face of the planet is ultimately tied to the origin of animal motility.”

The animal was a millipede-like creature a quarter-inch to an inch wide and up to 4 inches long that alternately dragged its body across the muddy ocean floor and rested along the way, leaving trails as long as 23 inches. The animal was an elongated narrow creature, with 50 or so body segments, a left and right side, a back and belly, and a head and a tail.

The origin of bilaterally symmetric animals — known as bilaterians — with segmented bodies and directional mobility is a monumental event in early animal evolution, and is estimated to have occurred the Ediacaran Period, between 635 and 539 million years ago. But until this finding by Xiao and his team, there was no convincing fossil evidence to substantiate those estimates. One of the recovered specimens is particularly vital because the animal and the trail it produced just before its death are preserved together.

Remarkably, the find also marks what may be the first sign of decision making among animals – the trails suggest an effort to move toward or away from something, perhaps under the direction of a sophisticated central nerve system, Xiao said. The mobility of animals led to environmental and ecological impacts on the Earth surface system and ultimately led to the Cambrian substrate and agronomic revolutions, he said.

“We are the most impactful animal on Earth,” added Xiao, also an affiliated member of the Global Change Center at Virginia Tech. “We make a huge footprint, not only from locomotion, but in many other and more impactful activities related to our ability to move. When and how animal locomotion evolved defines an important geological and evolutionary context of anthropogenic impact on the surface of the Earth.”

Rachel Wood, a professor in the School of GeoSciences at University of Edinburgh in Scotland, who was not involved with the study, said, “This is a remarkable finding of highly significant fossils. We now have evidence that segmented animals were present and had gained an ability to move across the sea floor before the Cambrian, and more notably we can tie the actual trace-maker to the trace. Such preservation is unusual and provides considerable insight into a major step in the evolution of animals.”

The study was supported by the Chinese Academy of Sciences, the National Natural Science Foundation of China, the U.S. National Science Foundation, and the National Geographic Society.

To Save The Science Poster, Researchers Want To Kill It And Start Over

[vc_row][vc_column][vc_column_text]

From NPR  |  June 11, 2019

Mike Morrison hardly looks like a revolutionary. He’s wearing a dark suit and has short hair. But we’re about to enter a world of conformity that hasn’t changed in decades — maybe even a century. And in there, his vision seems radical.

“We are about to walk into a room full of 100 scientific posters, where researchers are trying to display their findings on a big poster board,” says Morrison, a doctoral student in psychology at Michigan State University.

The idea of a science poster is simple. Get some poster-making materials and then slap on a title, the experimental methods and the results. Almost everyone has created a poster like this at some point — often in childhood, for a school assignment or a science fair.

In the world of science and medicine, posters are a huge deal. Major professional conferences invariably feature sessions that are devoted entirely to research posters.

Posters get tacked up on rows of boards that fill ballrooms and convention centers. Scientists often stand beside their posters, hoping their work will catch the eye of other experts milling around the room.

Tens of thousands of people go to these sessions every year. The annual meeting of the Society for Neuroscience alone draws about 30,000 people. Geophysicists, chemists, experimental biologists, planetary scientists, cancer researchers, physicians — no matter what the field, science and medicine professionals routinely go to conferences and that means spending time either making or viewing posters.

“A poster session, ideally, is this incredibly fertile ground for creative insight,” says Morrison, who met me at the annual meeting of the Association for Psychological Science in Washington, D.C. “You’re walking into a room, completely open-minded, and ready to hear and read findings around stuff that you didn’t even study before. If there are 50 posters here, it should transmit 50 new insights into your brain.”

Morrison says the reality is not like that. He believes poster sessions are usually a dispiriting waste of time for all involved.

Together, we walk through a ballroom filled with posters.

“Imagine you’re driving down the highway, and you see billboards, but instead of an image and a catchy phrase, there’s paragraphs of text all over the billboards,” says Morrison. “That’s what we’re seeing; we’re walking through a room full of billboards with paragraphs of text all over them.”

It’s impossible to take in unless you stop in front of a poster to read it. But there are so many posters that we just keep moving.

“It’s mostly noise. You’re just skimming desperately,” says Morrison, “and you’re going to miss a lot as you walk by.” Maybe people stop and engage with one or two posters, Morrison says, but it generally takes time to even figure out what the poster is about. That means researchers often spend time with a poster that turns out to be not all that significant for them.

In his view, this is more than just a bummer for scientists. Insights that could help humanity are buried in a jumbled mess that keeps them from being noticed by the right folks.

“So whatever you care about — whether it is exploring the universe sooner or curing a disease that your friend has — is happening slower right now than it should, because we have all these inefficient systems for disseminating knowledge among scientists,” says Morrison. “I think people assume that science is progressing as fast as it can, and it’s not.”

This really bugs Morrison. So a couple of months ago, he tweeted out a little video. It’s a cartoon he made about the nightmare that is the scientific poster session.[/vc_column_text][vc_video link=”https://www.youtube.com/watch?v=1RwJbhkCA58″ align=”center”][/vc_column][/vc_row][vc_row][vc_column][vc_column_text] 

In it, he proposed a new poster design. It looks clean, almost empty. The main research finding is written right in the middle, in plain language and big letters. There’s a code underneath you can scan with a cellphone to get a link to the details of the study.

This video went viral. His design is now popping up all over the place. In fact, in our visit to a poster session, we easily spot one that was surrounded by more traditional posters.

This poster says, in giant letters: “Jurors overwhelmingly vote ‘not guilty’ when an eyewitness is inconsistent in their identification, regardless of the actual reliability of that identification.” It was created by Kendra Paquette, a student at California State University, Fullerton.

“Everybody’s talking about this new poster format, they call it Poster 2.0,” says Paquette. “There’s a little video that I watched and it just made sense.”

Told that Morrison created the video, she greets him like he’s a rock star. “I’m totally supportive of it,” says Paquette, who admits that she felt a little nervous about trying this new format.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]But it seems like a lot of people have seen the video, she says, so “everyone’s like, ‘Oh, I wanted to try it, I’m so glad you did, now I’m going to do it next time.’ “

Clearly, Morrison’s idea has made an impression. On Twitter, scientists have been debating its merits and sharing photos of their own rejiggered posters.

One enthusiastic supporter is Christian Suharlim, a public health researcher at Harvard who became familiar with the problems of the usual wall-of-text design when he was involved with running an event called “Poster Day” at the Harvard T.H. Chan School of Public Health.

“It was just impossible to gain insights from the many posters presented in such a short time,” Suharlim told NPR. “When we ask people to rate ‘Audience favorite,’ they have small numbers of posters they evaluated, and are unable to provide their ratings effectively. It is just not an efficient design.”

That’s why he says Morrison’s new format has been made the required layout for a poster session on immunization economics that’s being held next month. It will have more than 40 posters from 20 countries, and all will feature the spare design.

“The current method is not effective in communicating research findings. For instance, in my field, we all want improvements in our life: vaccines for all diseases, easier delivery of vaccines, innovative way to finance vaccines, effective ways tackling vaccine hesitancy,” Suharlim says. “Experts are all coming to these conferences, and they have limited time to update their knowledge.”

Morrison is now working on experiments to study the effect of different poster designs. He wants to track people’s eyes to see whether they are more likely to read a simple poster and wants to see whether they actually absorb and retain more information from less-crowded posters.

In the meantime, he did what any scientist would do. He created a poster about his new poster.

“In the middle, it just says, ‘This poster could communicate findings more quickly,’ ” says Morrison.

And he presented it at this psychology conference — at a poster session.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_separator][/vc_column][/vc_row]

From VT News

The Virginia Tech Department of Geosciences is sponsoring a screening of the short documentary film “The Bearded Lady Project: Challenging the Face of Science,” followed by a panel discussion. Filmmakers say the movie challenges preconceptions about what a scientist looks like, focusing on the field of paleontology, seen as dominated by men.

The 30-minute film screens at 4 p.m. Sept. 20 at the Lyric Theatre in Downtown Blacksburg and will be followed by a discussion panel that includes the project and film’s originator, Ellen Currano, an associate professor at the University of Wyoming. Joining Currano will be Meryl Mims, an assistant professor in the Department of Biological Sciences, and Tina Dura, a postdoctorate researcher at Humboldt University in California, who will join the geosciences department in 2019.

The event is free and open to the public.

“We are privileged to welcome Dr. Currano herself — the originator of the Bearded Lady project — to Blacksburg to host both a showing of the film and a panel discussion,” said Steve Holbrook, head of the Department of Geosciences, part of the Virginia Tech College of Science. “Currano and her colleagues have created an inspiring short film whose main message is that anyone can become a successful scientist, regardless of gender or body type. People of all ages are invited to attend, regardless of facial hair status.

According to the film’s promotional website, “paleontologists are typically depicted as rugged, burly men, invariably with beards.” With this in mind, paleontologist Ellen Currano, filmmaker Lexi Jamieson Marsh, and photographer Kelsey Vance set out to turn the stereotype on its head by interviewing real-life female paleontologists who don false beards while on camera. Supported by a National Science Foundation grant, the movie seeks to change “the face of science and encourage a new generation of women to focus on a career in this field of study.”

[/vc_column_text][vc_video link=”https://vimeo.com/105722505″][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]

In the process of filming, Marsh, Vance, and director of photography Draper White traveled across the United States and the United Kingdom, interviewing female paleontologists and, of course, taking bearded portraits of scientists in their field, laboratory, museum, and classroom settings.

The film premiered last year and is available only for special screenings, such as the Lyric event. “I was fortunate enough to attend the premier of this film to a packed house in Laramie, Wyoming, last year, and I can attest that the film is wonderful,” Holbrook said.

Dr. Dana Hawley leads research linking bird immunity and pathogen virulence

From VT News

March 1, 2018  |  As annual flu shot patrons know, immune systems are not perfect and must be constantly reinforced to protect against rapidly evolving pathogens.

New research shows that, in the case of a common backyard bird, imperfect immunity to a dangerous pathogen that causes “bird pink eye” actually makes the pathogen stronger and more dangerous for its next victim.  The findings — from a multi-university team led by Virginia Tech — were published March 2 in the journal Science.

Unlike humans, wild birds do not receive vaccines and must rely on their natural immune systems to protect them from pathogen attacks. Immune systems have “memories” that allow organisms to recognize past abusers and ward them off. However, in the case of partial immunity, these memories aren’t always perfect and some pathogens make it through the door.

Dana Hawley, an associate professor of biological sciences in the College of Science who led the work, has long studied mycoplasmal conjunctivitis in house finches — a disease similar to “pink eye” in humans. In 2015, she determined that birds that eat at feeders are more likely to be infected with the disease, which causes red, swollen eyes and often blindness that results in death.

An increase in the severity of finch pink eye in recent years alerted Hawley and her collaborators to a potential link between bird immunity and pathogen virulence. She partnered with colleagues specializing in microbiology and modeling to measure how bacterial strains of varying strength fared in finches with or without pre-existing immunity to the pathogen.

The lab experiments showed that stronger or more virulent strains have a leg up for several reasons. One of the most surprising was that virulent strains generate more complete memory responses in finches, leaving weaker strains with few hosts to infect. In contrast, weaker strains produce only partial immune memory, leaving the door open for more virulent strains to invade.

Results from that experiment were then modeled to reveal how a pathogen might move through an entire population of finches. The model showed that pathogen strains that came to dominate in an experimental population with incomplete immunity were almost twice as harmful as those that dominate in the absence of immunity. Thus, incomplete immunity is likely what’s driving the evolution of more harmful strains of the finch bacteria in nature.

“Our results are not just important for finches. Many human pathogens and other animal pathogens also cause only incomplete protection against reinfection. Thus, the potential is there for the host immune response to favor more harmful strains in many types of hosts. The immune response is an incredibly powerful agent of protection for hosts, but in this case, imperfection can be deadly,” said Hawley who is an affiliate of the university’s Global Change Center, an arm of the Fralin Life Science Institute.

“The shift to favor more harmful pathogens that we observed in the modeling results is a very dramatic increase, suggesting that immune responses have key effects on the evolution of this pathogen and others,” said Arietta Fleming-Davies, co-first author on the paper and currently an assistant professor of biology at the University of San Diego. “What I found unique about working on this study was that the patterns in the experimental data were so strong — no matter how we looked at it, the same important immune effect popped out.”

“This is really groundbreaking since, most of what we know about host-pathogen co-evolution is in the context of interventions like vaccinations,” said Ariel Leon, a doctoral student in Hawley’s lab and co-author on the paper. “Additionally, this research provides valuable insight into what is driving pathogens to become more dangerous in wild animals, which we know to be important sources of emerging infectious diseases in humans.”

“The experiments reported in the Science paper explain elegantly why pathogen virulence increased once the disease had become established,” said André Dhondt, co-author, Edwin H. Morgens Professor of Ornithology and director of Bird Population Studies at the Cornell Lab of Ornithology. “Curiosity-driven research on birds can generate insights that are relevant for human health.”

“This study provides convincing evidence from a natural bird system that we should be looking at the relationship between the virulence of the primary infection and the strength of the memory response that the host generates,” said Ann Tate, an assistant professor of biological sciences at Vanderbilt University who was not involved in the research.  “When the two are correlated, lower virulence strains could be their own worst enemies, creating a population of hosts that are resistant to them but not the higher virulence strains that remain. The burning question now is, in which and how many disease systems are microbial virulence and the strength of host memory correlated? This is most likely in cases where microbial numbers or microbe-induced damage act as a kind of adjuvant for the generation of immune memory, and those conditions are likely to be met for a number of important human and animal infections.”

This work was funded by a $2.3 million NIH grant to Hawley as part of the NSF-NIH-USDA Ecology and Evolution of Infectious Diseases program. Hawley’s team involved seven collaborators from five institutions, including microbiologists, ecologists, and mathematical modelers.

Other co-authors on the paper include Paul D. Williams, a former postdoctoral research associate at Princeton University; Andrew P. Dobson, a professor in the department of ecology and evolutionary biology at Princeton University; Wesley M. Hochachka, senior research associate at the Cornell Lab of Ornithology; David H. Ley, professor emeritus of poultry health management at North Carolina State University; and Erik E. Osnas, a biometrician at the U.S. Fish and Wildlife Service.

“Between Earth and Sky: Climate Change on the Last Frontier” screened April 12 at the Lyric

From VT News

The documentary film “Between Earth and Sky: Climate Change on the Last Frontier” will be screened at 7 p.m. on April 12 at The Lyric Theatre in downtown Blacksburg. David Weindorf, the film’s executive producer, will be on hand to introduce the movie to a Blacksburg audience.

Sponsored by the Global Change Center at Virginia Tech and the Department of Crop and Soil Environmental Sciences at Virginia Tech, the event is free and open to the public. Among the many scientists interviewed in the documentary is John Galbraith, an associate professor of crop and soil environmental sciences in the College of Agriculture and Life Sciences and a Virginia Cooperative Extension specialist.

“This film educates through interviews about an important subject that is not widely acknowledged by people who live far away in warmer climates,” said Galbraith. “They learn that a dangerous feedback loop has started. Rising temperatures and enhanced wave action erode and melt permafrost, accelerate carbon dioxide and methane release, warming the planet further. The effects are global.”

The film mixes interviews with some of the world’s leading scientists in climate change and arctic soils with the day-to-day struggle of native Alaskans living on the front lines of global warming. The film shows the calamity of climate change that has started in Alaska but will soon engulf the globe, according to the film’s producers.

Dr. David Weindorf

“Alaska has been the source of myth and legend in the imagination of Americans for centuries, and what was once the last frontier of American expansion has become the first frontier of climate change,” said Weindorf.

The film especially focuses on the island of Shishmaref, which has been home to the Inupiaq people for thousands of years. As sea ice retreats and coast storms increase, the people of Shishmaref are faced with a disappearing island and a $200 million price tag to move their people, which will result in an untold cost on their culture and history.

Permanently frozen ground known as permafrost in the Artic and Subarctic sequesters 40 percent of the Earth’s soil carbon. Alaska has experienced the largest regional warming of any state in the United States, increasing 3.4 degrees Fahrenheit since 1949. In fact, this increase is more than twice the warming seen in the rest of the United States, according to the United States Environmental Protection Agency. Alaska’s warming has created a feedback loop of carbon to the atmosphere and the thawing of permafrost.

“The film provides a compelling glimpse of how climate change is directly affecting Alaskans today, not implications in the distant future. Similar coastal impacts are currently being experienced by communities around the globe, including high population centers in the U.S., such as Miami, Florida. We are well past the point of abstractions; the effects of climate change are observable right now,” said Bill Hopkins, director of the Global Change Center. “The film also highlights the disproportionally large effects of climate change on certain segments of society, raising important issues of environmental injustice.”

Producer David C. Weindorf currently serves as associate dean for research for the College of Agricultural Sciences and Natural Resources and BL Allen Endowed Chair of Pedology in the Department of Plant and Soil Science at Texas Tech University. Weindorf is 20-plus year member the Soil Science Society of America, past chair (2016) of the pedology section, and a licensed Texas Professional Geoscientist.

Director Paul Allen Hunton is a three-time Emmy award winning documentary film maker and serves as managing director of Texas Tech Public Media.

The film is supported by the USDA-Natural Resources Conservation Service, Texas Tech Public Media, Soil Science Society of America, BL Allen Endowment in Pedology, and the University of Alaska-Fairbanks.

For more information about the event, please contact the Global Change Center at 540-231-5400 or visit their website.

The Lyric Theatre is located at 135 College Ave. in Blacksburg.

IGC Fellows Estrada and Medina work on issues that address declining species worldwide

Video: In the rainforests of Central America, a research team studies a skin disease that may be the tipping point for amphibian life on the planet.

[hr]From VT News

As the clock ticks, populations of endangered species decline and threaten the functioning of healthy ecosystems.

Pollution, hunting, habitat degradation, climate change, and invasive species have dealt blows to global biodiversity. Climate change alone is putting one in six species on Earth at risk of extinction, according to a meta-analysis of 131 published studies in the journal Science.

Virginia Tech researchers from multiple colleges and disciplines, many affiliated with the Fralin Life Science Institute, are doing what they can to save populations of endangered species, including honeybees, frogs, and the horned anole lizard.

FROGS

In the rainforests of Central America, a research team studies a skin disease that may be the tipping point for amphibian life on the planet. A disease caused by chytrid fungus already threatens about 500 frog species. The disease disrupts frog skin, potentially resulting in death.

“Chytrid fungus is responsible for many amphibian population declines and extinctions across the world, causing scientists to claim it to be the root of the greatest disease-associated loss of biodiversity in recorded history,” said Lisa Belden, an associate professor of biological sciences in the College of Science and faculty member with Virginia Tech’s new Global Change Center. “The disease has already contributed to the decline of the Panamanian golden frog, which is now thought to be extinct in the wild.”

Belden’s team is interested in how a frog’s skin microbiome, or the collection of bacteria on its skin, helps it survive chytrid fungus exposure.

Doctoral students Angie Estrada and Daniel Medina collect microbiome samples from frogs in the rainforests of Panama.
Doctoral students Angie Estrada and Daniel Medina collect microbiome samples from frogs in the rainforests of Panama.

Two of Belden’s doctoral students, who are also Fellows with the Interfaces of Global Change program, travel to Panama to collect microbiome samples from frogs living in the rainforests.

Angie Estrada of Panama City, Panama, investigates how chytrid fungus infection varies during wet and dry seasons in the lowlands of central Panama.

“Some species of frog seem to be doing well at a few sites, while disappearing from many other sites,” Estrada said. “I want to try to understand why they persist and what is special about these sites so that we can try to mimic that success in other places.”

Daniel Medina, also of Panama City, examines how amphibian skin microbes affect chytrid fungus in low and high elevations. Frogs in warmer, lower elevations are generally able to withstand infection better than those in cooler, higher elevations.
