Dead men might not tell tales but fossilized apes and the soil around them may change a narrative. That’s what happened recently when a large collaboration of researchers gathered clues from an ape fossil in Moroto, Uganda that lived 21 million years ago and from a detailed analysis of the soil.

Scientists have long thought apes started climbing upright, which is an important evolutionary step, all those years ago to reach fruit in a habitat dense with trees. Recent evidence from two publications in the journal Science, however, suggest that the habitat included grassland and woodlands.

James Rossie, Associate Professor in the Department of Anthropology at Stony Brook University, studied the teeth of the fossil, called Morotopithecus, to determine what this ancient ape ate.

“The important thing about the teeth of Morotopithecus is a shift towards folivory” or leaf eating, Rossie said. “The surface of the molars were elongated with well-developed crests” which indicate that this primate consumed leaves rather than fruit.

By contrast, molars of animals that eat fruit are more rounded. Additionally, carbon isotope dating of the enamel suggest that they fed on water-stressed plants. This discovery and analysis changes not only the narrative of this particular ape species, but also of the evolutionary progression and habitat of primates.

This analysis indicated that apes lived in areas of open woodlands, where there were patches of trees separated by stretches of grassland about 10 million years earlier than scientists originally believed. During the miocene period, they would have had to evade predators such as Simbakubwa, an extinct carnivore that was larger than a lion.

“It was very unexpected that an ape with upright, versatile climbing abilities was living in a seasonal woodland with open, grassy patches, rather than in a closed tropical forest,” said Laura MacLatchy, a Professor in the Department of Anthropology at the University of Michigan and the leader on the study.

“The findings have transformed what we thought we knew about early apes, and the origins for where, when and why they navigate through the trees and on the ground in multiple different ways,” Robin Bernstein, Program Director for Biological Anthropology at the National Science Foundation, said in a statement. “The effort outlines a new framework for future studies regarding ape evolutionary origins.”

The fossils Rossie and his colleagues examined including the lower part of a face, the palate, upper teeth, a couple of vertebrae, the lower jaw, and a complete femur. It’s unclear if these fossils came from one individual or from a collection of apes. With considerable wear and tear on the teeth of the upper jaw, the owner of those bones was an adult, Rossie said.

By studying the bones as puzzle pieces that fill in a narrative, researchers concluded that the smaller, thick femur, or thigh, bone helped the ape climb quickly and effectively up the trunks of trees.

The longer legs of a human push us away from trees, making it harder to climb, while the shorter, sturdy legs of an ape enable it to get closer to the trunk and reach lower branches quickly. 

Apes that fed on leaves would likely have had larger bodies to accommodate the need for a longer digestive tract. A heavier animal that navigated through trees would run the risk of falling to the ground if their weight caused a branch to break.

By climbing upright, apes could distribute their weight more evenly over several branches, enabling them to maneuver through the trees to the leaves while reducing the strain they put on any one branch.

In a second paper published together as a part of this analysis, soil researchers studied the environment at Moroto and at several other sites of similar age across eastern Africa.  These soil scientists determined that the early habitat included forests and grasslands.

Cooperative work

Rossie believes the work of numerous scientists over a long period of time not only represents a paradigm shift in thinking about ape evolution and the environment in Africa, but also in the way scientists across a wide range of expertise collaborate.

The researchers who trained Rossie and his colleagues were more competitive and guarded, he said. They didn’t share information with each other about their findings and wanted other researchers to learn about their findings through journal publications.

“We decided to take a different strategy” about a dozen years ago, he said. “It occurred to us that these separate silo attempts to reconstruct these environments were incompatible, with different methods and strategies. We couldn’t put it together into a coherent picture.”

By working together with the same methods, the scientists had comparable data and developed a coherent picture. Such broad collaborations across a range of fields required a “bit of a leap of faith,” he added. The scientists knew and trusted each other.

Indeed, Rossie and MacLatchy have known each other since the early 2000s when MacLatchy first asked Rossie to study other fossils.

Bringing numerous researchers across a range of expertise was a “game theory experiment,” Rossie added. Researchers could have published smaller papers about each site more quickly, but chose to combine them into the more meaningful synthesis.

MacLatchy suggested that the work on this project that involved sharing data across multiple sites, as well as joining forces in a range of expertise, makes it possible to reconstruct habitats with much greater detail.

“We are also able to obtain a regional perspective, which is not possible if interpretations are based on individual fossil sites,” she said. “I’d like to think this kind of collaboration will become standard.”

A resident of Centerport, Rossie is a hockey fan and is pulling for the Islanders.

He enjoys studying teeth because a single tooth can provide considerable information about an animal’s place among other species and about its strategies for getting and processing food.

His professional studies have come full circle. As a college junior at St. Lawrence University, he attended a field school run by Harvard University and the National Museum of Kenya at Lake Turkana. Almost every moment of that experience made him more eager to pursue paleontology as a career.

“As fate would have it, my field project is now centered on an area on the west side of Lake Turkana that I first visited back in 1995,” he explained.

The Turkana Basin Institute serves as his home base during the field season and he is grateful for their ongoing logistical support.

As for future work, Rossie is studying the fossils of at least four different species of apes in Lake Turkana in Kenya.

The clock didn’t care about COVID-19.

Time marched forward at the same pace that it always has, and yet, the pandemic, which altered so much about our experiences, seemed to alter the fourth dimension.

Initially stuck in homes, we developed new routines, worked at kitchen tables or desks and spent considerably more time with family members and our pets throughout the day than anticipated.

For students, the pandemic altered opportunities and created challenges unseen for a century.

And yet, each year, as in this one for our daughter, the annual rite of passage of a graduation following an amalgam of typical and unique experiences awaits.

As these students march to “Pomp and Circumstance,” listen, or half-listen, to graduation speakers and glance at their supportive families who are thrilled to mark the milestone, celebrate their achievement and come together, what will be going through the minds of these new graduates?

Some may reflect on the typical academic stresses and achievements that helped them earn their diploma. They will consider the hours spent on lab experiments, the late-night workouts at the gym before a big game, and the endless rehearsals for shows and performances. They may bask in the attention of friends they made from around the country or around the corner.

They also might consider the parts they missed or the sudden change from their expected pathways.

Students, who were studying abroad, suddenly needed to return home as quickly as possible. They had to make sure they had their passports and visas, booked flights, and cleared out of rooms that might have just started to feel like home.

Others, like our daughter, raced back to their dorms from spring break, packed everything up and drove home.

As the weeks and months of uncertainty caused by a pandemic that gripped the country for more than two years progressed, some students recognized that they would not have some opportunities, like studying abroad. They might have filled out forms, learned important words in a different language, and chosen classes carefully that they couldn’t take.

Student-athletes, actors and artists, many of whom worked hard for months or longer together, were on their own as fields and stands stood empty.

These students may recognize, more than others, that plans may need to change in response to uncertainty caused by health concerns, storms or other issues.

Amid these disruptions and changes in routine, students and their families needed to pivot. They connected with friends online, entertained themselves at home, often on electronic devices, and tried to learn online.

Undoubtedly, they missed learning opportunities inside and outside the classroom. I heard from numerous students about lowered expectations and abridged syllabi, with American History classes designed to go to 2016 that stopped in 1945, at the end of World War II.

It will be up to students to fill those holes and to recognize the opportunities to become lifelong learners.

Indeed, as people search for a label for these graduates, perhaps the list will include the pivot generation, the empty stadium generation, and the virtual learning generation.

Historically, commencement speakers have exhorted graduates to embrace the opportunity to learn, to question the world around them and to seek out whatever they need.

After the pandemic adversely affected some of the students, perhaps some of them will learn and develop a stronger and more determined resilience, enabling them to keep their goals in sight even amid future uncertainties.

In the meantime, they and we can embrace the normalcy of a routine that allows them to watch the familiar clock as it slowly moves through the minutes of a commencement address.

Michael French in front of a mobile radar antenna.

By Daniel Dunaief

Michael French

 

When he was in elementary school in Hamden, Connecticut, Michael French was several miles away from an event that would shape his life. A tornado touched down, causing extensive damage, knocking out power lines and injuring 40 people. The violent storm was traumatizing, causing him to hide in the closet during routine summer storms.

By the time French attended college at Cornell University, these powerful and potentially devastating storms had become an “interest and fascination,” he said, leading him to major in atmospheric sciences.

After graduating from college, he received an offer from Professor Howard Bluestein at the University of Oklahoma (OU) for a master’s program. A consultant for the movie Twister starring Helen Hunt and Bill Paxton, Bluestein was one of the first to put a weather radar on the back of a truck to collect data in severe storms and tornadoes. French also earned his PhD at OU.

These days, French, who is an Associate Professor in the School of Marine and Atmospheric Sciences at Stony Brook University, spends parts of his time traveling to places in the southeast in trucks with unique and emerging instrumentation, typically Doppler weather radar, gathering data about severe thunderstorms and tornadoes.

French has seen about 25 tornadoes. The closest he’s come to these violent storms is about a kilometer away, which occurred in 2004. When he’s conducting research, he is more concerned about lightning, which frequently occurs around thunderstorms that produce tornadoes.

When he’s collecting data, French has to get out of the truck to stow the antenna among other tasks. “Automatically, that means you’re in danger,” French said. “There’s nothing you can do about it, except try to minimize your time” outside. Two or three times when he was earning his PhD, lightning struck within a quarter of a mile of his location.

Better sampling

In his research, French described himself as a “pure observationalist.”

A main theme of his research is whether the nationwide network of fixed-site radar can be used by forecasters to predict whether a thunderstorm will produce a tornado and, if it does, how likely it is to be a significant or violent storm. 

French is also interested in exploring what leads to tornado dissipation and whether forecasters can use radar analysis to make dissipation predictions.

Looking at time scales of 30 seconds or fewer, he studies how tornadoes evolve, including how they tilt, how their intensity changes with height, and their motion. He can estimate these characteristics with phased-array radar technology, in which the beam of the radar is steered electronically.

Scientists like French can tap into archived data from a network of 160 radars stationed throughout the country. He would like to use information from the past 10 to 15 years to analyze hundreds of supercell thunderstorms to find commonalities among those that produce tornadoes and those that don’t.

“Ideally, in the future, such information, to the extent it exists, can be leveraged by forecasters to better assess the likelihood of a storm producing a tornado,” French explained.

Many of his ideas for research projects come from reading the results of papers from colleagues who use computer models to simulate storms and tornadoes. In a model, the scientists can control conditions like temperature and humidity. French thinks about ways to verify the findings using observational data.

Funded by the National Oceanic and Atmospheric Administration, French participates in the Propagation, Evolution and Rotation in Linear Storms field experiment (called PERiLS). 

Running from February through May in the southeast, the experiment studies tornadoes within a different type of storm, referred to as squall lines. The tornadoes that form in these storms persist or form overnight, often hitting while people are sleeping and are unprepared to protect themselves.

He is working with Stony Brook Professor Pavlos Kollias in using mobile phased array radar to collect data over short time scales of these squall lines when they’re producing tornadoes.

In areas where people live in mobile homes, these squall line tornadoes can lift the home, damaging homes and threatening the lives of people as they sleep.

Exciting findings

French uses a radar called dual polarization, which provides information about the size, shape, orientation and type of precipitation. He is interested in whether this technology can identify differences in storms to predict the formation of tornadoes.

In dual polarization, there are a few signatures of storms that hold some promise of differentiating between those that produce tornadoes and those that don’t.

Working with an algorithm to identify the ZDR column, which is a proxy for the size of the updraft, developed by Darrel Kingfield at the National Center for Atmospheric Research, French analyzed 200 supercell storms and found that the ZDR column was larger in storms that produce stronger tornadoes and was smaller or nonexistent in storms that did not.

Forecasters don’t have a way yet to automate the size of the ZDR column in real time.

In an email, Bluestein suggested that French’s studies, including on how tornadoes dissipate, can “contribute to improved short term forecasting.”

Bluestein, who has seen over 100 tornadoes, also suggested that two papers from French that related drop size distributions estimated from polarimetric radar data in supercells were “original and rather novel. This work has implications for estimating the intensity of pools of cool air in storms, which can be related to tornado formation.”

Dinner table conversations

A resident of Stony Brook, French lives with his wife Jennifer, who is a hydrometeorologist at Vieux & Co. The couple met when they were at the University of Oklahoma. 

French said his wife, who storm chased when she was in Oklahoma, knows the safety measures he uses to mitigate the risks. 

While French studies these storms because of their destructive power and the need to understand more about how and where they will form, he also has an appreciation for them.

At a distance, when these storms aren’t impacting people and when he can’t hear the roar of the wind, French describes tornadoes as a “wonder of nature” that have an “aesthetic element to them that is really astounding.”

As for his childhood concern about these storms, French feels that he “ultimately channeled [his fear] in a positive way.”

An indulgence is like a gift we give ourselves.

No, it’s not always healthy, which is why we sometimes limit our indulgences.

These indulgences, however, can go a long way to restoring our equanimity.

In a nonscientific survey of people of different ages who were willing to respond to a question about their indulgences, I received a range of interesting responses. Sharing them, I hope, gives you a chance to consider what indulgence could improve your morning, afternoon, day or week.

Several people suggested that desserts were an indulgence. Maybe that’s because so many restaurants market their marquee confection as a “warm indulgence” or a “decadent indulgence.”

Not everyone enjoys the same sugary treat. Alex appreciates a warm chocolate chip cookie, while his wife Michelle suggested that any dessert would do for her and that she doesn’t discriminate, which, I suppose makes her sugar sensitive.

Chocolate made several people’s lists, although, given the size of the market for chocolate, consumption of this sweet is likely more of a routine than a periodic indulgence.

A close friend suggested that gelato was one of his favorite indulgences. He also shared a list of other pleasures, which includes skiing in fresh powder and sailing in Port Jefferson harbor.

Sticking to the food realm for a moment, a mother and her son both considered pizza an indulgence.

A friend in his mid-20s enjoys jalapeno kettle brand potato chips dipped in sour cream, while his longtime girlfriend partakes in a matcha latte.

In the frozen food section, a friend seeks out Italian ices.

A neighbor with four young kids enjoys shopping and jewelry, although some of the joy of those moments may come from getting out of the house and spending time on her own.

Another neighbor whom I’ve seen running regularly didn’t hesitate to add alcohol to the list of indulgences. His drink of choice, which he shared instantly after getting the question, is bourbon.

Apart from food and drinks, a host of activities made the list.

A man in his mid-80s who leads an active life appreciates the opportunity to swim as often as possible.

For several people, reading a book without interruption is a welcome indulgence, breaks up the routine and transports them to other places, other times and other thoughts.

Julie, a friend whose company we like to keep regularly, enjoys siting on a beautiful, breezy beach with a book.

Kim, a friend I’ve had for well over a decade when our children started going to birthday parties together, shared a list that includes facials, a spa day, travel and chocolate eclairs. 

Noelle, who savors the chance to read a good book as well, loves foot massages, floating in a pool with her eyes closed and breathing underwater. Noelle is a scuba diver who hasn’t breathed underwater in a while, but is building up the momentum to return to the depths to search for some of her favorite aquatic friends.

Several close friends immediately highlighted the joy of a massage. That one resonates for me, as I accumulate stress in my upper back and neck and I can feel myself relaxing the moment someone works out the knots.

Another close friend loves spending time with her mother in a garden, listening to the origin story of flowers that came from the gardens of other relatives.

After listening to all these indulgences, I felt transported into the peace in other people’s lives. Asking about indulgences is a pleasant social icebreaker. To borrow from “Saturday Night Live”: indulgences, talk amongst yourselves.

The weather outside has been frightful and local researchers suggest the trend has been anything but delightful.

Over the last year, the country has confronted numerous violent and intense storms, causing property damage and leading to evacuations and rescues. Just last week, Fort Lauderdale, Florida received a month’s worth of rain in an hour amid a storm that dumped over two feet of rain on the city. Such a torrential storm isn’t unique to Florida, as areas including Dallas experienced significant rains last August that crippled the city.

Malcolm Bowman

“The extremes are increasing,” said Malcolm Bowman, Professor Emeritus at the School of Marine and Atmospheric Sciences at Stony Brook University. “It’s part of the prediction of climate science.”

Indeed, as the atmosphere becomes warmer, the increase in water vapor raises the amount of rain in a particular storm, added Edmund Chang, Professor in the School of Marine and Atmospheric Sciences at Stony Brook University. Chang and other local scientists discussed their concerns and potential cause for optimism amid the approach of the 54th anniversary of Earth Day.

Climate Change report

This March, the Intergovernmental Panel on Climate Change (IPCC) released a report that suggested that climate change was worsening and that the Earth will likely increase by more than the 1.5 degrees Celsius above pre-industrial revolution averages that would lead to numerous environmental damage.

“Since the last IPCC report, there has been a lot more research looking at these weather extremes,” Chang said.

Edmund Chang

In warmer temperatures, which have increased on average for the Earth by 1.1 degrees, storms carry significantly more precipitation.

While it is outside the realm of his own research, Chang said that other researchers have demonstrated that storms in the Northeastern United States have had an increase in higher precipitation events, which is also linked to the fact that these storms are moving more slowly, drenching areas with rain before slowly leaving.

Chang is particularly concerned about sea level rise. “I have lived in coastal areas all my life,” he said. “We know that the sea level is rising. The rate of rise is accelerated.” Counteracting the effects of melting ice sheets in Greenland and the Antarctic are among the more difficult processes to mitigate, he added.

In his own research, Chang is assessing the bias in models that predict whether a season will likely be stormier than average. He is looking at how model biases may impact the accuracy of longer range forecasts.

Different models have different biases, he explained. Weather channel fans, and those who watch storm models for approaching hurricanes and other events, may recognize that meteorologists often overlay American and European weather models, particularly when describing approaching hurricanes.

In Chang’s research, he has found that combining different models improves the forecast. “A better way of improving models is to understand where the model biases or error comes from” rather than averaging errors that cancel each other out, he said.

Reasons for optimism

Chang believes there are reasons for optimism about efforts to mitigate the effects of climate change. The current administration is “starting to impose more stringent emissions controls from vehicles,” he said. “It’s getting a bit more encouraging.”

In other areas, world leaders have also taken encouraging steps towards protecting the oceans and biodiversity. Last month, the United Nations announced the legal framework for a High Seas treaty, which protects biodiversity, reduces pollutions and shares ocean resources. After 20 years of work, 193 countries verbally agreed to a treaty to protect 30 percent of the world’s oceans by 2030.

Ellen Pikitch

The treaty is “of monumental importance,” said Ellen Pikitch, endowed professor of Ocean Conservation Science and executive director of the Institute for Ocean Conservation Science at the School of Marine and Atmospheric Sciences at Stony Brook University. “The treaty will enable marine protected areas (MPAs) to be created in areas outside national jurisdictions and allow fisheries management of species in international waters not currently covered by regional agreements.”

Citing recent reports, Bowman said global emissions of carbon dioxide have declined 2 percent over the last 12 months. “There are moves, even in China, to bring in solar and wind” power, he added.

Local concerns

As storms hit areas like Florida and Texas, Long Islanders frequently wonder about the readiness of the region for future storms. Indeed, Hurricane Sandy wreaked havoc in the Middle Atlantic states in 2012.

“If we had another Sandy, it could be just as bad or worse,” said Bowman, who has been a part of a storm surge working group in New York.

In the fall, the Army Corps of Engineers published a tentatively selected plan for the area after the administration of President Biden (D) reinstated the Harbor and Tributary Study, which was temporarily halted in 2019. The plan doesn’t involve enough protection along the harbor with concrete and steel, Bowman said. 

“They say [concrete] is terrible,” Bowman said. “We say it’s necessary.”

Any plan for flooding in and around the New York area would not only have to address how to handle a storm surge that brought water in from the ocean. It would also have to provide a way for any heavy rains to get out.

The reality of global warming is “scary,” said Bowman. And yet, “how many people are changing their living habits?”

As for his native New Zealand, Bowman said a tornado touched down in recent weeks, which is “unheard of.” While the tornado was not on the scale of such twisters in Kansas, he said it ripped through several homes.

New Zealand, with a population of five million people, is moving toward using electric cars, while the country is also considering a genetic modification in cattle that reduces the production of methane from when they burp or pass gas.

“There’s a big push in New Zealand to do its bit,” Bowman said.

The New York City Mayor’s Office and the Trust for Governors Island may soon announce the winner for the global competition to create the Center for Climate Solutions.

In October, Stony Brook University was announced as a finalist for the ambitious project. Northeastern University and the City University of New York and the New School were the leaders of the other bids.

A multidimensional environmental effort designed to educate the public, offer climate solutions and ensure equitable climate solutions, the competition, which was launched in 2020 by former New York City Mayor Bill de Blasio (D), is expected to create over $1 billion in economic impact and create 7,000 permanent jobs.

The winner or winners will create a space on the island that features views of the Statue of Liberty and the Brooklyn Bridge with several key features. The center will provide a way to study the impacts of climate change, host a living lab that provides entrepreneurs and nonprofits that can test and showcase their climate solutions, serve as an urban center for environmental justice organizations, feature dormitories and housing and provide space for New Yorkers and visitors to discuss climate change.

Partners on the Stony Brook proposal include Brookhaven National Laboratory, International Business Machines, Georgia Institute of Technology, Pace University, Pratt Institute, University of Washington, Duke University, Moody’s Corporation, Rochester Institute of Technology, SUNY Maritime College, Oxford University, URBS Systems, General Electric and other business, nonprofit and on-Island partners.

The proposals offered ways to support interdisciplinary research focused on urban adaptation, urban environments, public policy, environmental justice and public health.

At the same time, the finalists offered educational programs for students all the way from K-12 through graduate and adult education.

The center will provide workforce training opportunities, incubators and accelerator spaces for nonprofits and entrepreneurs working on climate and public programming.

The selection committee that is choosing the winners includes representatives from the Trust for Governors Island, Mayor Eric Adams’s (D) Office of Climate and Environmental Justice, the Mayor’s Office of Equity and the New York City Department of City Planning.

“New York City is facing some of the most complex climate adaptation challenges in the world,” Kizzy Charles-Guzman, executive director of the Mayor’s Office of Climate and Environmental Justice, said in a statement when the finalists were announced last October. “The Center for Climate Solutions will bring together actionable science, community-based partnerships and innovative and equitable solutions to communities on the frontline of the climate crisis.”

Grace Mehl, far right, at the Association of the United States Navy Dining in 2019.

By Daniel Dunaief

Grace Mehl had made it onto her first navy ship, passing through a fiercely competitive process in which the U.S. Navy only had openings for two out of 60 women. 

Her first boss, who was a warrant officer, made his feelings about her presence on the ship known. “I don’t believe women belong on a ship,” he told Mehl in 1980. “I don’t believe they belong in the navy. If you do your job, we’ll get along fine.”

That conversation, however, was among the only ones Mehl, who grew up and now lives in Smithtown, had with people about whether her gender could affect her ability to serve. At the same time, members of the navy sometimes grumbled about the expanding role of women in the armed forces.

“I heard a lot of gruff from older guys talking about having women in the navy,” said Troy Wussow, an enlisted man who served aboard the USS Shenandoah with Mehl after the ship was christened in 1983. “The old salt saw it as problematic.”

Mehl often won over others with her professionalism, talent, and willingness to work.

When he met Mehl, Wussow and others were building an office that they wouldn’t complete by a deadline because supplies hadn’t arrived. When he presented the situation to Mehl, she told them to get lunch. While the others ate, Mehl redesigned the building with the supplies on hand. Wussow was grateful for her solution, which enabled him and the rest of the crew to execute their orders.

“She solved the problem for us, which was an extraordinary beginning,” Wussow said.

Indeed, Mehl also impressed her superiors, rising through the ranks to become one of the first five women to command a navy combatant ship. For 14 years of Mehl’s career, women only joined navy combat ships when they volunteered. In 1994, however, the navy started assigning women to ships the way they had men. The executive officer sent some of those frustrated female navy crew to see Mehl.

“When they walked into my state room and looked at me, they just stopped” being upset, Mehl said. They couldn’t tell Mehl how unfair it was when she had been living that life.

“After they got there, they started to learn that it wasn’t so bad and it was just another job,” she said, “although you were floating around while you were doing it.”

Commanding respect

A graduate of SUNY Binghamton, Mehl, who grew up on a chicken farm, had a desire to get a job that makes a difference and to see the world. Her sister Jane and her college roommate had also joined the military, so she already had examples of women who had gone into the service.

Her father John Albert Mehl had also been in the Army Air Corps during World War II. A tail gunner, the Mehl patriarch had been stationed in England and France and had been on 65 missions. Her sister was an Army nurse.

Despite the army family connection, Mehl entered the navy because she didn’t want her sister to have the ability to boss her around.

“The army wasn’t big enough for both of us,” Mehl said.

Wussow suggested that Mehl had an effective approach with those under her command and with superior officers. Officers either commanded or demanded respect, Wussow suggested. Mehl was in the former category, listening to problems, working with people to solve them, and following and enforcing rules.

Dave Gellene, who was her executive officer when she was the commanding officer of the Gunston Hall, appreciated her naval skills. “She was able to maneuver the ship the best I’ve seen,” he said.

Gellene, who served on active duty in the Navy for 23 years and has been a government civilian for the navy for 15 years, said Mehl maneuvered the ship expertly through all kinds of weather and in densely populated areas where other boats were nearby.

Her ability to control the ship “gained the crew’s confidence,” Gellene said. Even early in Mehl’s tenure as commanding officer, Gellene could tell that the spirit of the ship improved dramatically the day after she took command.

The Bronze Star

The navy awarded Mehl the Bronze Star for her work in 1999, when the armed forces provided support during the humanitarian crisis in the former Yugoslavia.

“I was very proud of the people on the ship,” Mehl said. “I got to wear the Bronze star, but I didn’t earn it: my crew earned it.”

Gellene recalled that the marines who were disembarking for the peacekeeping mission had to get ready each day, only to learn that the mission encountered additional delays.

Mehl, whom Gellene said kept everyone informed of orders and important information, had agreed to play bagpipe music on the day the mission would occur which was “very motivating.”

Mehl and the crew of the Gunston Hall also provided critical assistance in 1999, when an earlier enormous earthquake rocked Turkey, killing over 17,000 people.   With Mehl at the helm, the ship tied up at a dock and the crew put up tents for displaced residents.

“The crew would have stayed forever if they could,” Gellene said. “Under her leadership, she kept everyone motivated and focused.”

In a less stressful but important moment for the ship, Gellene also recalled how the Gunston Hall was stationed in North Carolina during the Super Bowl in 1999. Before the widespread use and availability of cell phones, the ship had to face a particular direction to get a good satellite feed to watch the game. Mehl stayed at the helm, keeping the ship at the right angle so the crew could watch the Broncos defeat the Falcons in Super Bowl 33.

“You could imagine the morale boost,” Gellene said.

Current contributions

Mehl has established numerous connections to the Long Island community. Having given talks to students in elementary and high schools, she said people know her as “the Navy lady.”

She volunteers with Vietnam Veterans of America, is on the Board of Directors of the United Veterans Beacon House, and serves on Veterans Court.

Mehl also earned a certification as Eastern Apicultural Society Master Beekeeper and is the Education Director of the Long Island Beekeepers club.

Looking back on her service, Mehl believes she did something important during her two decades in the navy.

“I feel like I opened a door for women to be able to follow in the path that I broke for them,” she said. “I feel that we have come a long way in the military.

Ideally, doctors would like to know about health threats or dangers such as diseases or chronic conditions before they threaten a person’s quality of life or expected lifespan.

On a larger scale, politicians and planners would also like to gauge how people are doing, looking for markers or signs that something may be threatening the health or safety of a community.  

Researchers in computer science at Stony Brook University have been designing artificial intelligence programs that explore the language used in social media posts as gauges of mental health.

Recently, lead author Matthew Matero, a PhD student in Computer Science at Stony Brook; senior author H. Andrew Schwartz, Associate Professor in Computer Science at Stony Brook; National Institute on Drug Abuse data scientist Salvatore Giorgi; Lyle H. Ungar, Professor of Computer and Information Science at the University of Pennsylvania; and Brenda Curtis, Assistant Professor of Psychology at the University of Pennsylvania published a study in the journal Nature Digital Medicine in which they used the language in social media posts to predict community rates of opioid-related deaths in the next year.

By looking at changes in language from 2011 to 2017 in 357 counties, Schwartz and his colleagues built a model named TrOP (Transformer for Opioid Prediction) with a high degree of accuracy in predicting the community rates of opioid deaths in the following year.

“This is the first time we’ve forecast what’s going to happen next year,” Schwartz said. The model is “much stronger than other information that’s available” such as income, unemployment, education rates, housing, and demographics.

To be sure, Schwartz cautioned that this artificial intelligence model, which uses some of the same underlying techniques as the oft-discussed chatGPT in coming up with a model of ordered data, would still need further testing before planners or politicians could use it to mitigate the opioid crisis.

“We hope to see [this model] replicated in newer years of data before we would want to go to policy makers with it,” he said.

Schwartz also suggested that this research, which looked at the overall language use in a community, wasn’t focused on finding characteristics of individuals at risk, but, rather at the overall opioid death risks to a community.

Schwartz used the self-reported location in Twitter profiles to look at representation of a community.

The data from the model, which required at least 100 active accounts each with at least 30 posts, have proven remarkably effective in their predictions and hold out the potential not only of encouraging enforcement or remediation to help communities, but also of indicating what programs are reducing mortality. Their model forecast the death rates of those communities with about a 3 percent error.

Both directions

Schwartz explained that the program effectively predicted positive and negative changes in opioid deaths.

On the positive side, Schwartz said language that reflected a reduction in opioid mortality included references to future social events, vacation, travel and discussions about the future.

Looking forward to travel can be a “signal of prosperity and having adventures in life,” Schwartz said. Talking about tomorrow was also predictive. Such positive signals could also reflect on community programs designed to counteract the effect of the opioid epidemic, offering a way of predicting how effective different efforts might be in helping various communities.

On the negative side, language patterns that preceded increases in opioid deaths included mentions of despair and boredom.

Within community changes

Other drug and opioid-related studies have involved characterizing what distinguishes people from different backgrounds, such as educational and income levels.

Language use varies in different communities, as words like “great” and phrases like “isn’t that special” can be regional and context specific.

To control for these differences, Schwartz, Matero and Giorgi created an artificial intelligence program that made no assumptions about what language was associated with increases or decreases. It tested whether the AI model could find language that predicted the future reliably, by testing against data the model had never seen before.

By monitoring social media in these specific locales over time, the researchers can search for language changes within the community. 

Scientists can explore the word and phrases communities used relative to the ones used by those same communities in the past.

“We don’t make any assumptions about what words mean” in a local context, Schwartz said. He can control for language differences among communities by focusing on language differences within a community.

Schwartz recognized that fine refinements to the model in various communities could enhance the predictive ability of the program.

“If we could fully account for differences in cultural, ethnic and other variables about a community, we should be able to increase the ability to predict what’s going to happen next year,” he said.

With its dependence on online language data, the model was less effective in communities where the number of social media posts is lower. “We had the largest error in communities with the lowest rates of posting,” Schwartz explained. On the opposite side, “we were the most accurate in communities with the highest amounts” of postings or data.

Broader considerations

While parents, teachers and others sometimes urge friends and their children to limit their time on social media because of concerns about its effects on people, a potential positive is that these postings might offer general data about a community’s mental health. The study didn’t delve into individual level solutions, but these scientists and others have work that suggests this is possible.

As for his future work, Schwartz said he planned to use this technique and paradigm in other contexts. He is focusing on using artificial intelligence for a better understanding of mental health.

“We hope to take this method and apply it to other outcomes, such as depression rates, alcohol use disorder rates,” post traumatic stress disorder and other conditions, Schwartz said. “A big part of the direction in my lab is trying to focus on creating AI methods that focus on time based predictions.”

I don’t know if teeter-totters exist anymore. Remember them? Two people sit on opposite ends of a board, with a support in the middle. They start at the same height, facing each other, with legs extended. One person pushes up while the other bends his or her legs and gets closer to the ground. The one on the bottom pushes off, while the one on the top heads toward the ground.

The image seems like an apt simile for conversations.

You see, one person talks, while the other listens, and then, the listener becomes the speaker and the speaker the listener. Such simple descriptions don’t work in group dialogue.

In one-on-one conversations, these interactions sometimes involve prolonged periods when one person is on the ground, and the other is stuck in the air, waiting for the speaker to stop talking so he or she can come to the ground and share some thoughts and reactions.

I have had numerous experiences where it seems the teeter-totter gets stuck in one position, much more often than not with me dangling in the air. Yes, I am a decent listener. No, I don’t hear or register everything my wife or anyone else tells me. I do, however, have an ability to listen to a meandering story that includes many detours, recitations of facts that aren’t germane to the main thread of the story, and to self editing. To wit:

“It was a Tuesday that I lost my dog.”

“No, wait, it was a Wednesday and it wasn’t my dog, it was my cat.”

“No, no, it was a Tuesday, and it was neither my dog nor my cat, but it was my car keys. The point is that I lost something before I found it. That was also the day I got a new job.”

Somewhere along the lines, I wonder what happened to the fine art of conversational teeter-tottering, with a predictable and relaxing back-and-forth rhythm.

The stories from another person continue, with one bleeding into the next one so endlessly that I feel like I’m listening to excerpts from several different books on tape.

As I listen, I wonder what my role is. Clearly, the other person doesn’t want or need to hear much from me.

I sometimes wish there were a swimmer’s clock behind the person’s head, which would allow me to time the minutes between sounds like “uh huh,” and “oh yeah,” and “really? no way! That’s terrible/wonderful/amazing/ridiculous!”

It’s the Mad Libs version of listening to the same story, or a variation of that story, while throwing in the appropriate, or sufficiently irreverent, adjective.

I raise my eyebrows periodically in response to the tone of the person’s voice, going through lists of chores in my head, wondering who didn’t give this person a chance to speak when he or she was younger.

An actual pause periodically arrives. My toes dig happily into the welcome sand beneath me, reveling in the auditory opening.

I don’t want to wait too long to say something, because people aren’t always comfortable with quiet, which can restart an ongoing monologue.

After I express an idea, or sometimes just a phrase, I feel my body ascending back into space. Wait, did I not make it clear that I wasn’t done? How am I dangling above the ground again?

Suspended in mid-air, I suppose I could consider those moments as the equivalent of listening to a bird singing a repetitive tune echoing among the eaves.

Perhaps in the future, we can create a verbal shorthand when we feel we’ve lost conversational balance. Maybe, we can just say “teeter-totter” when we need to speak.

Johanna Mitra was part of the rescue team to save the endangered greater bamboo lemur.

By Daniel Dunaief

Johanna Mitra traveled a long way from her childhood home on the Upper West Side of Manhattan to join an effort to save the critically endangered greater bamboo lemur.

A graduate of Stony Brook University, Mitra took a class led by Distinguished Professor Patricia Wright that set her on a memorable and extraordinary course.

Mitra “came up to me after class and asked if she could help” with her research and with conservation, Wright recalled.

Johanna Mitra was part of the rescue team to save the endangered greater bamboo lemur.

Mitra started by cataloging photos for about three months twice a week. Wright saw that Mitra had been writing blogs for an environmental nonprofit and had asked Mitra if she’d like to apply for the opening as the Communications Officer at Centre ValBio, a research station Wright created in Madagascar.

“The next thing I knew, a couple of months [and an undergraduate degree in Ecosystems and Human Impact] later, I was packing a bag to go to Madagascar!” Mitra explained in an email.

Mitra sent her parents, Nilo and Ursula Mitra, a group photo where it was “fairly evident that she was the youngest person and only woman,” Nilo Mitra said in an interview.

The Mitra parents felt reassured that the research station had been around for decades and that a large number of foreign researchers use the site, which gave her parents confidence that the team would be able to deal with any safety or health issues that arose during the translocation.

Still, that didn’t completely allay Nilo Mitra’s concerns when he learned about the crocodiles that lived in some of the rivers his daughter would cross.

After watching nature shows, Mitra’s father cautioned her not to stand too close to the shore. While she was away, he also wished he had told her not to go too close to the reeds, as crocodiles hide there before attacking.

Mitra’s trip didn’t involve any hair raising interactions with crocodiles. In fact, she felt disappointed because she “would have liked to see one – from a safe distance,” she said.

Mitra and the translocation team encountered individual zebus, which are a type of cow with a lump behind its head that makes it look like it’s wearing shoulder pads.

Mitra “could sense hesitation and tentativeness in the group when we were hiking” as the group gave the animal, which can be aggressive in defending its turf, a wide berth.

During the two-day trip to translocate the lemurs, Mitra rode in a car, truck, and canoe. When the roads, which were severely damaged by the raging waters and 80 mile per hour winds of Cyclone Freddy, were impossible to navigate, she and the team traversed difficult terrain on foot.

She hiked along rolling hills that “looked very beautiful but were degraded,” Mitra said. She walked up and down hills that had deep patches of mud.

The team also crossed streams, walked through rice paddies and fields and climbed steep, rocky slopes.

Fortunately for Mitra, the group hired porters to carry the equipment and her backpack. She only had responsibility for maneuvering herself and a camera bag. 

During the hike, she was concerned about getting a camera she had borrowed to document the journey wet, particularly when she was traveling in a canoe that sat low in the water.

When she waded through streams, she hoisted the camera on her shoulder or near her head.

Back home in Manhattan, her parents watched three videos about Madagascar, studied local roads and tried to track their daughter’s whereabouts.

When her journey started, they were able to track her phone for about 90 minutes, until the signal “vanished off the face of the Earth,” her father said.

After several days, her mother called Wright to ask if she’d heard anything. Wright assured her that the crew was fine and they had completed their mission of trying to bring back enough greater bamboo lemurs to increase the population from the current number of about 1,000.

“We are extraordinarily proud” of the work she did to get the job and to help in this conservation effort, her father said.

As for the experience, Mitra expressed awe at the opportunity.

“The whole thing felt unreal,” Mitra said. “I felt like I was a part of something incredibly meaningful.” The expedition “made it clear that a lot goes into saving species, but it’s worth it,” she concluded, despite the few rapid heart beats from her proud, concerned and supportive parents.
