Andy Thliveris: Remember the Undergrads

Andy Thliveris: 'Remember the Undergrads'

 

In December 2022, Andrew Thliveris BS’83 made a special trip to Salt Lake City with his wife Lauren. They joined the School of Biological Sciences in a belated (due to the pandemic) remembrance of K. Gordon Lark who had passed away more than two-and-a-half years earlier in April 2020.

Vice Chair and Ophthalmology Residency Training Program Director at the University of Wisconsin-Madison’s Department of Ophthalmology and Visual Sciences, Thliveris, until his retirement in September, was also Chief of Ophthalmology at the W.S. Middleton VA and holds the rank of Professor at the School of Medicine in Madison. At the event “Andy” remembered that as an undergraduate he worked in the Lark lab for five years and that Lark had a profound impact on him. “He changed my life,” reported Thliveris whose main message to the faculty and friends who had gathered was “Remember the undergraduate students.”

Thliveris also surprised many by announcing that through his affiliation with the Carl Berg Foundation he had arranged to fully fund the Lark Endowed Chair with a check for $430,000. The Lark fund was established in 2017, followed in July 2022 with a campaign to “re-boot.” The ambition was to achieve the level of endowed professorship through an anonymous, matching donation of $250,000. But with Thliveris’ brokered gift—added to many others from generous individual donors—the K. Gordon Lark Endowment was elevated to the more prestigious level of endowed chair.

With his characteristic humor, Thliveris was eager to recall his time in Lark’s lab.  He confessed to being that “pesky nerdy undergrad, high-maintenance, known to call Gordon at 11 pm on several occasions, [until] finally, Gordon, then speaking to his post-doc Paul Keim, [said], ‘You’ve got to get this guy under control because I have no idea what the hell I told him last night.’”

Lark wasn’t the only one who mentored, managed and otherwise inspired that “pesky” undergrad. Addressing Nobel laureate and Lark colleague Mario Capecchi who was at the event as well, Thliveris remembered how “you spent many hours with me in your office when you taught biochemistry. I was always in there.” He also recalled Baldomero “Toto” Olivera and his amazing cone snails which would later prove critical in the advance of alternatives to opioid pain relievers, as well as the late Naomi Franklin who helped bring sequencing to Lark’s lab and its occupants.

Regarding Martin “Marty” Rechsteiner, now in the U’s  Spencer Fox Eccles School of Medicine, Thliveris recounted his professor “who on the first day of his class of trembling undergrads told us that if we memorized every word out of this mouth then we might just pass his class.”

Clearly, Thiliveris’ sojourn at the U as an undergraduate where he majored in biology and geology & geophysics, and later attended the U’s medical school where he earned his MD, prepared him well. Following his ophthalmology residency at Wisconsin in 1998, he was a postdoctoral research fellow as a launch to his auspicious 28-year career. After joining the faculty in 2000, he took on the position of Veterans Affairs Hospital service chief and later, in 2014, vice chair of resident education and residency director  — roles he held until his retirement and during which time he trained countless physicians, including many of the department’s own faculty.

'Ball of energy'

At the announcement of his retirement, Thilveris said, “Our residents are beyond amazing, and the dedication from the faculty to our program has made short work for our education team. We have a very proud tradition here and are poised to continue for generations to come.” In hearing the news, many in Wisconsin responded with memories of his meticulous teaching, patience, wisdom, and, of course, his delightful sense of humor.

“I am beyond grateful to Andy for his role in my own training and in my recruitment back to UW-Madison,” said Evan Warner, MD. “His kindness, openness, and genuine concern for each and every colleague, trainee, and staff member has been foundational to our department culture, and it is such a privilege to be a part of it. As residency program director, he has been a ball of energy with so many ideas and such passion for seeking feedback and making things better for the residents.”

Thliveris will also be remembered for his work as director of the department’s cataract extraction phacoemulsification course. In this three-year progressive course, medical and veterinary ophthalmology residents, UW and visiting medical students, and pre-residency fellows from around the country learn the latest cataract surgical techniques. Daniel Knoch, MD who will assume the role of veterans affairs service chief following Thliveris' retirement recalled how “There are dozens of residents, numerous faculty, and thousands of patients that Andy has helped through his after-hours videos, toolbox approach to surgical teaching, probing questions, and high standards.” Anna Momont, MD who has assumed the role of ophthalmology residency training program director acknowledged that because of Thliveris’ “unwavering dedication to our residents and their training,” is leaving the department nationally recognized and a “highly sought-after residency program.”

'Full steam ahead'

To recognize Thliveris’ lasting legacy, the department dedicated its new Surgical Skills Training Facility in his honor. The new space, which expands the department’s training capacity by providing 10 training pods, each outfitted with state-of-the art equipment, will be instrumental in training the next generation of eyecare specialists. “While the decision to retire was a very emotional one,” says Thliveris, it comforts me greatly to know that I am leaving things in such capable hands. Full steam ahead.”

Whatever Gordon Lark said during those 11 pm phone calls to Andrew Thliveris must have been spectacular. And now with the K. Gordon Lark Endowed Chair poised to announce its first recipient soon, the undergraduate has made sure the legacy of founder of the School of Biological Sciences will continue.

Clenched fists and full beards

Clenched fists and full beards

Humans have not evolved to do any one thing. We evolved to make tools. We evolved to tell stories. We evolved to explore and more. And one thing that some scientists are now coming to recognize is that we also evolved to fight — with each other.

David Carrier

David Carrier is a professor in the School of Biological Sciences at the University of Utah, and the author or co-author of scores of studies suggesting humans’ physiological characteristics were driven by running after other animals and fighting with each other.

In 2021 he and his team of researchers, including U Professor of Mechanical Engineering Steven Naleway and Ethan Beseris HBS’18, were awarded the Ig Nobel Peace Prize for a study exploring whether beards may serve an evolutionary purpose to protect the jaw during a fistfight. A parody of the Nobel Peace Prize, the IG Noble in all of its categories is awarded for research that, at least at first blush, seems odd, silly or weird.

Since the award, Carrier has been hosted to discuss his research in greater, more sober detail ,including recently on Utah Public Radio’s podcast UnDisciplined with Matthew LaPlante.

Have humans, in particular males, evolved to fight each other? That’s the broader question that interviewer LaPlante asks Carrier in this September 7, 2023 episode.

 

 

A warming climate could make cities even less hospitable to wild mammals

urban wildlife In a Warming Climate

 

Human-driven climate change could worsen the effects of urbanization on native wildlife, suggests new research based on analyses of data recorded by 725  trail cameras set up in and around 20 North America cities, including Utah’s urban areas along the Wasatch Front.

The main finding was that urbanization’s negative effects on wildlife are tougher on larger-bodied animals and are worse in the less vegetated cities in drier regions, such as Phoenix and Salt Lake City, according to University of Utah wildlife biologist Austin Green, one of the study’s many coauthors.

“Those cities that don’t have as much rainfall have higher average temperatures, the effects that they had on wildlife were greater than in cooler and wetter cities,” Green says.

These findings are based on thousands of photos of wild animals, namely 37 species of native mammals that live in or near cities, ranging from squirrels to black bears. The images were recorded by motion-triggered camera traps operating in the summer of 2019 in places used for outdoor recreation within cities and up to two kilometers beyond the urbanized boundary. To ensure privacy, images of people were automatically deleted by the program that uploaded the photos, according to Green who is aa postdoctoral fellow in the College of Sciences' Science Research Initiative.

Led by Arizona State University biologist Jeffrey Haight, the study published Monday in the journal Nature Ecology & Evolution.

Haight and collaborators from around the country analyzed data from 725 camera traps to assess the composition of native mammal communities and the relative occupancy of each species. In partnership with the Urban Wildlife Information Network, the team covered Salt Lake City, Chicago, Los Angeles, San Francisco Bay Area, Atlanta and Austin and Edmonton in Canada and 13 other cities in the course of some 20,000 camera days.

Why Scientists Haven’t Solved the Mystery of the OMG Particle

Solving The Mystery Of The 'OMG Particle'

 

Below the snow-covered peaks of the Andes Mountains, among scattered rocks and the scrub of prairie bushes, there sits at this very moment a 12-ton polyethylene tank holding 3,000 gallons of pure water.

 

All around it, spread out in every direction over an area nearly the size of Rhode Island, are 1,599 more such tanks, each identical to the first. These lonely sentinels have their eyes on the sky, patiently observing what human eyes cannot in the hopes of solving a mystery that began on another continent and more than three decades prior — a mystery that started with the Oh-My-God event.

It was the night of October 15, 1991. The University of Utah had set up an experimental observatory called the Fly's Eye in the isolation of Dugway Proving Ground, a sprawling 800,000-acre tract of land used by the U.S. Army to test biological and chemical weapons since the 1940s. On that night the Fly's Eye detected something called an air shower, a miles-long explosion of streaming particles invisible to the human eye and caused by high-energy interactions in the upper atmosphere. Each of the telescope’s detectors were designed to point at a different part of the field of view, in a similar way to insects’ compound eyes. It was this that earned the telescope its name. “We were hoping we might pick up something really unusual,” says David Kieda at the University of Utah, who worked on the telescope at the time. (Read more about the Fly's Eye Array here.)

Scientists looked at the data they'd collected and worked backward to deduce the properties of the space-borne particle that led to the air shower. The results weren't just shocking — they were thought to be impossible. They called their discovery the Oh-My-God particle.

While the Oh-My-God particle still remains the most energetic cosmic ray ever detected, a handful of others in the off-the-scales range have been observed in the years since, confirming that it wasn't a miscalculation or instrumentation failure, but in fact a real event. This is why 1,600 giant water-filled tanks have been installed in a grid formation across 3,000 square kilometers of the arid Mendoza region of Argentina. These are the specialized detectors of the Pierre Auger Observatory, forming an array designed to capture evidence of other extremely high-energy cosmic rays. "The quest for identifying the sources of the most energetic particles in the Universe continues," says Carsten Rott, chair of the Department of Physics & Astronomy at the U. "[But] not only at the Auger detector in Argentina, but also right here in Utah with the Telescope Array experiment."

Volcanism That Drove Ancient Global Warming

Volcanism that Drove ANCIENT Global Warming

Geological evidence extracted from the floor of the Atlantic Ocean affirms a long-standing theory that greenhouse gas emissions associated with volcanism drove catastrophic climate change 56 million years ago.

A new study by an international team of scientists—including University of Utah geologists—examined hundreds of core samples in search of clues to what drove rapid warming that triggered the deep sea die-off marking the transition from the Paleocene to the Eocene epoch. A paper published this month concludes that large volumes of methane—a potent greenhouse gas—escaped from hydrothermal vents on the ocean floor during a period of intense volcanic activity.

Around the time the Americas and Europe started spreading apart to form the North Atlantic, Earth’s temperatures spiked by 5 degree Celsius and ocean chemistry changed during a 200,000-year period known as the Paleocene-Eocene Thermal Maximum, or PETM. This resulted in a major extinction event that wiped out a lot of deep marine life and accelerated evolution among terrestrial creatures, with mammal species becoming more diverse.

Ancient analogue for today’s climate change

“This article provides evidence for hydrothermal venting playing a major role in the global warming event that happened during the PETM by showing vents in the North Atlantic erupted in very shallow water and coincided with the onset of the PETM,” said Sarah Lambart, a U professor of geology and geophysics. “While their origins are different, the PETM presents similarities with global warming today in that the sediments that were heated were very rich in hydrocarbons. So this event can be used as a natural analogue for how the Earth system responds to the rapid burning of fossil fuels.”

She noted that today’s anthropogenic climate change is 100 times faster than what transpired at the end of the Paleocene.

Scientists have long believed the PETM was triggered by rapid and massive releases of carbon dioxide (CO2) and methane (CH4) into the atmosphere from geological sources.

Methane is a far more powerful greenhouse gas than carbon dioxide, although it eventually breaks down in the atmosphere. Over short time frames, methane could have a major impact on the climate, and the scientific team thinks that might be the case with the PETM, which coincided with the volcanic-driven continental breakup that created the Atlantic.

Loudest Stadium … according to science

Geoscience and football meet at Rice-Eccles

 

U geoscientists are now measuring the actual seismic impact of Big Time college football on the Salt Lake City campus and live tweeting the measurements during games, starting with Thursday’s Florida-Utah matchup.

Ahead of the Utes’ season opener, seismologist and Utah season ticket holder Jamie Farrell installed the seismometer in the Rice-Eccles Stadium to measure and record Earth shaking associated with fans’ response to on-field action during the Utes’ home games.

“We’re going to try to convert the amount of energy that gets released either over an entire game or if there’s a big event, where it shakes a lot, and try to convert that into equivalent magnitude, how much energy is put into the ground,” Farrell said. “But if not, we can compare different things, like when the team ran into the stadium, when we scored our first touchdown or this was a third-down stomp.”

Farrell is an associate research professor in the Department of Geology and Geophysics, where he helps oversee the U of U Seismograph Stations, or UUSS. He is an expert in the use of seismic waves to characterize the Earth’s crust, with a particular focus on the volcanism under Yellostone Park.
