Timing can mean the difference between life and death for young geladas (an Old World monkey species). Geladas whose fathers remain leaders of a social group for as much as a year or more have a better chance of survival than those whose fathers are displaced by new males under a year after they’re born. 

New males who enter a social group can, and often do, kill the young of other males, giving the new male leaders a chance to impregnate the female members of their social group who might otherwise be unable to conceive.

The odds of a new male leader killing a young gelada are about 60 percent at birth, compared to closer to 15 percent at around a year of age, according to researchers at Stony Brook University (SBU).

Additionally, pregnant gelada monkeys often spontaneously abort their unborn fetuses once a new male enters the group, as the mother’s hormones cause a miscarriage that enables them to dedicate their resources to the future progeny of the next dominant male.

At the same time, the survival of females depends on becoming a part of a group that is just the right size.

Jacob Feder, a graduate student at SBU, and Amy Lu, Assistant Professor in the Department of Anthropology in the College of Arts and Sciences at Stony Brook, recently published a paper in Proceedings of the Royal Society B that explores the ideal group size that optimizes the longevity of females and the number of their offspring.

The researchers discovered a Goldilocks effect. By studying the behavioral and group data for over 200 wild geladas over the course of 14 years, they determined that a mid-size group with five to seven females has the greatest benefit for their own fitness and for the survival of their offspring.

“There tends to be a trade off” in the dynamics that affect female geladas in different groups, Feder said. Females in the biggest groups face a higher risk of takeovers and takeover-related infanticide, since males are more likely to try to dominate a part of larger social groups where they have greater reproductive opportunities.

By contrast, individuals in the smaller groups may live on the periphery of a multi-group dynamic. These females are less protected against predators.

In their native Ethiopia, geladas are vulnerable to leopards, hyenas, and jackals, among others.

For the females, the survival of their offspring depends on the ability of males to remain in the group long enough.

“The male turnover is one of the major drivers of their reproductive success,” explained Feder.

Researchers have seen new males enter a group and kill infants born from another father. The infants, for their part, don’t often recognize the need to avoid new males, Lu said.

When males enter big groups, females often have to reset their reproduction.

Groups with about nine to 11 females often split into units of four to seven, Feder said. A new male might become the leader for half of the females, leaving the remaining male with the other half. Alternatively, new males may take over each group.

The pregnant females who are part of a group with a new male will spontaneously abort their offspring about 80 percent of the time, as females “cut their losses,” Feder said

About 38 percent of females live in a mid-sized group that is close to optimum size.

Gelada charm

According to Feder and Wu, geladas are a compelling species to research, Feder and Wu said.

Feder found his visits to the East African nation rewarding, especially when he had the opportunity to watch a small female named Crimson.

An important part of daily life for these primates involves grooming, where primates comb through each other’s hair, remove insects and, in many cases, eat them.

Crimson, who was a younger member of the group when Feder started observing geladas, didn’t have much grooming experience with this activity. Instead of running her hands over the body of her grooming partner, she focused on her mouth. Her partner’s wide eyes reflected surprise at the unusual grooming choice.

One of the favorites for Lu was a monkey who has since passed away named Vampire. A part of the V group, Vampire was taller and bigger than most adult females. She displaced male geladas, some of whom were larger than she, almost as often as they displaced her.

“If you go out in the field enough, you know the individuals pretty well,” Lu said. “They all have their own personalities. Some of them walk in a different way and react to situations differently.”

A resident of Centereach, Feder grew up in northern Connecticut, attending Wesleyan University as an undergraduate, where he majored in music and biology. A bass guitar player, Feder said he “dabbles in anything with strings.”

In fourth grade, Feder read a biography of Dian Fossey, which sparked his interest in biology.

While he has yet to combine his musical and science interests with geladas, Feder said these monkeys have a large vocabulary that is almost as big as chimpanzees.

Lu, meanwhile, started studying geladas as a postdoctoral researcher. They’re a great study species that allow scientists to ask compelling questions about reproductive strategies. “At any point, you can follow 20 social groups,” Lu said.

Lu, whose two children are four years old and 16 months old, said she has observed the similarities between human and non-human primate young.

“Babies throw tantrums, whether it is my child or a gelada infant protesting being put on the ground,” she described in an email. Gelada infants use a sad “cooing” sound. Sometimes, the sad cooing sound is real and sometimes “they just get what they want.”

She hasn’t scored a point or dished out an assist in a college basketball game since 2009. That hasn’t stopped Ashley Langford, Stony Brook University’s first-year women’s basketball coach, from mixing it up with the players.

A point guard who graduated from Tulane University and who holds the school record for the most assists, scored over 1,000 points, and, despite being five feet, five inches tall, brought down 403 rebounds for 25th in school history, Langford plans to tap into her playing experience at Stony Brook.

“I’m a hands-on head coach,” said Langford, who most recently was associate head coach at James Madison University in Virginia. “I’m a demonstrator.”

Langford, who took over for Caroline McCombs this year when the former coach joined George Washington University, believes she can help a team that won back-to-back America East Championships by stepping onto the floor during practices and drills.

When she’s guarding them, she wants to “see them do a move,” she said. “At a certain point, they get too good” for her skills, which is when she pats herself on the back, especially after she sees her players exuding increased confidence.

Langford is pleased with the start of her time at Stony Brook, where she has felt welcomed and supported by Athletic Director Shawn Heilbron and President Maurie McInnis.

“This is a big reason why I chose to come here,” Langford said. “The administration is great and the president has been awesome.”

Langford appreciates how Heilbron knows the names of so many student-athletes, which is consistent with her approach to coaching.

Langford believes her players and the coach should have similar expectations.

“I need to be connected to my players, and I want them to be connected to me,” Langford said. “I want players to come into my office and talk. I want that relationship.”

Langford has been working within the limitations of National Collegiate Athletic Association rules during the summer. She hopes to use this time to build a rapport with her team and help them learn her terminology and the drills she runs.

“I want to give them a preview” about her and the program, Langford said.

In making the transition from playing to coaching, Langford said she has tried to improve and grow. She believes she and her team should constantly strive to improve.

Coaching is “less about basketball and more about how you connect with your players,” Langford said.

To be sure, that connection doesn’t mean she coddles the team. She strives to be honest without sugarcoating the message. 

“When they’re doing well, I’m going to tell them,” she said. “When we need to be better, I’m going to tell them that, too.”

Langford explained that basketball has changed considerably since her playing days, as players have more resources available to them. She sang the praises of Elizabeth Zanolli, assistant athletic director for Sports Medicine, who supports the basketball and other teams.

Players also have nutritionists, dietitians, and strength and conditioning support, which improve the overall health and endurance of the athletes.

On the court, the men’s and women’s games have increasingly emphasized the value of the three-point shot, which means that most of the points in a game come from in the paint close to the basket or outside the three-point line, where long-range shooters can rack up points quickly.

Langford doesn’t see much of a difference between the men’s and women’s games.

“I want players to pass, dribble and shoot,” she said. “It’s that simple.”

Rocks may not speak, move or eat, but they can and do tell stories.

Recognizing the value and importance of the ancient narrative rocks on Earth and on other planets provide, NASA sent vehicles to Mars, including the rover Perseverance, which landed on February 18 of this year.

Perseverance brought seven instruments, most of them identified by the acronym-loving teams at NASA, that carry out various investigations, such as searching for clues about a water-rich environment that may have sustained life about 3.5 billion years ago.

Several instrument teams developed and monitor these pieces of equipment, including Joel Hurowitz, Associate Professor in the Department of Geosciences at Stony Brook University and Deputy Principal Investigator on the Planetary Instrument for X-ray Lithochemistry, or PiXL.

In addition to the instrument leads, NASA chose participating scientists who can contribute to several teams, providing scientific support for a host of questions that might arise as the rover explores the terrain of the Red Planet 128 million miles from Earth.

Rebecca Smith, a post-doctoral researcher at Stony Brook in Geosciences Professor Scott McLennan’s lab, is one such participating scientist.

“I get to move around between all these different groups, which is fun,” said Smith, whose appointment will last for three years. While the Mars2020 program takes up about 20 percent of Smith’s time, the remainder is focused on the Mars Science Laboratory mission. Smith is likely to spend almost all of her time on Mars2020 starting this September.

Smith has helped make the science plans for the rover. The scientist and other researchers help select targets for the instruments that will help answer specific science questions. For this work, they collaborate with different science teams. Smith plans to get more involved with specific instrument teams soon, including SuperCam, PiXL and Sherloc.

For Smith’s own research, the scientist has a suite of rock samples that include lacustrine carbonates and hydrothermally altered volcanic rocks. The volcanic rocks formed under conditions that might be analogous to those once present in Jezero crater, where the rover landed and is currently maneuvering. The crater is just north of the Martian equator and has a delta that once long ago contained water and, potentially, life.

On Earth, Smith is using versions of the SuperCam, PiXL, and Sherloc to understand how these rocks would look to different instruments and determine what baseline measurements they need to tell the different types of rocks apart using the instruments aboard the rover.

Smith has studied rocks on Earth located in Hawaii, Iceland and the glaciers in the Three Sisters Volcanic Complex in Oregon.

Many planetary geologists use Earth as an analog to understand geologic processes on other planets. It is still uncertain if the climate of early Mars was warn and wet or cold and icy and wet, Smith explained in an email, adding, “It is possible the minerals we see with the rovers and from orbit can help us answer this question.” 

Most of the work the scientist been involved with is trying to understand how Mars-like volcanic rocks chemically weather under different climates.

Through previous research on Mars, scientists discovered that large regions had poorly crystalline materials. The poorly crystalline nature of the materials makes them difficult to identify using rover-based or orbiter-based instruments.

“The fact that they could have formed in the presence of water makes them important to understand,” Smith explained.

Part of the work Smith is doing is to understand if poorly crystalline material formed by water have specific properties that relate to the environment or climate in which they formed.

Smith said the bigger picture question of the work the teams are doing is, “was there life on Mars? If not, why not? We think that Mars, for the first billion years or so, was pretty similar to Earth around the same time and Earth developed life.”

Indeed, Earth had liquid water on its surface, which provided a habitat for microbial life about 3.5 billion years ago.

The ancient rock record on Mars provides a better-preserved history because the Red Planet doesn’t have plate tectonics.

“Based on what we know about Earth, if life ever developed on early Mars, it would likely have been microbial,” Smith wrote.

Other goals of Mars2020 include characterizing the climate and the geology. Both goals focus on looking for evidence of ancient habitable environments and characterizing those to understand a host of details, such as the pH of the water, the temperature and details about how long the water was on the surface.

Part of the reason NASA put out a call for participating scientists is to “bridge instrument data” from different pieces of equipment, Smith explained.

“I love the collaborative nature of working on a team like this,” Smith offered. “Everybody is interested in getting the most important information and doing the best job that we can.”

Smith enjoys the opportunity to study potentially conflicting signals in rocks to determine what they indicate about the past.“Geology is just so complex. It’s a big puzzle. Forces have been acting over a very long period of time and forces change over time. We are trying to tease apart what happened and when.”

While Smith works at Stony Brook, the post-doctoral scientist returned to California during the pandemic to live closer to her family. After finishing the current research program, Smith plans to remain open to various options, including teaching.

Smith appreciates the opportunity to work on the Mars 2020 mission, adding, “I’m really grateful for that during this past year in particular.”

A few weeks ago, I wrote about a conversation I imagined having with an alien who I  envisioned landing in my backyard. Here’s how I figure a conversation between an alien who speaks the language of my dog and our beloved pet would go:

Alien: Tell me about those humans?

Dog: They talk to each other constantly.

Alien: Does the noise bother you?

Dog: It’s not particularly problematic, but it is hypocritical.

Alien: What do you mean?

Dog: When we’re in the backyard or out for a walk, they tell us to be quiet or something much meaner when we speak to other dogs. They don’t want us to bark with other dogs, and yet they talk nonstop like they have so much to say. 

Alien: What else is different about humans?

Dog: They never smell each other’s butts. By the way, do you mind if I hump your tentacle?

Alien: That’s fine. So, why is smelling each other’s butts important?

Dog: We get all kinds of information, about where the dog has been, what grass it’s eaten. Speaking of which, are you planning to feed me sometime soon? I’ve been making those cute eyes at you during our entire ride and you haven’t felt the need to toss me food.

Alien: So, what do humans do all day?

Dog: They seem to be slaves to some small object they hold. Every time it buzzes or beeps, they immediately look at it, as if they will get in trouble if they don’t. Sometimes, they say something, like “Oh my gosh, I forgot,” or “Oh no, you don’t,” and then they run somewhere. I think that object gives them directions.

Alien: Are they pleasant?

Dog: Sometimes. They seem incredibly happy when they scratch our bodies and we move our legs. Once in a while, I do it if I think one of them is having a tough day.

Alien: Do they seem intelligent?

Dog: Hard to say. They don’t understand the value of sleep. They spend hours each day with the things in their hands or staring at a flickering screen. At night, they look at another screen on the wall in their bedroom.

Alien: What’s your favorite game to play with them?

Dog: There’s a big difference between my favorite and their favorite game. They love to play something they call “fetch.” They can be pretty simple and easy to please. When they like something, they keep doing it.

Alien: And your favorite game?

Dog: I call it the “mud game.” When everyone is wearing something fancy, nice or white, I go into the backyard and find the darkest mud. I come in and jump on them or spread mud on the floor.

Alien: Any other observations?

Dog: Just as they start to bring compelling smells into a room, they spray or roll on the scent of flowers over their bodies. I tried to copy them by rolling in the flowers outside, but they didn’t like that.

Alien: What do they say to you?

Dog: They seem especially fond of the word “sit.” Whenever someone comes into the house and they don’t know what to say to the other person, they tell me to “sit” and the other person laughs and nods. 

Alien: Do you like humans?

Dog: Humans, in general, are fine. I am not all that fond of those people who make unhappy faces and say they are not a “dog person” but a “cat person.” Who could possibly find those hissing creatures more appealing than dogs?

I recently spoke with several scientists about work they were doing for the National Aeronautics and Space Administration, or NASA. In chatting with them, it became clear that researchers love acronyms the way my dog loves anyone willing to toss him a few morsels of food.

I was just thinking about how much time I’d save in my life if I could start my own set of acronyms, all designed to create word efficiency and to develop the equivalent of an insider’s club.

For starters, how about OKWAM? As in, this place is definitely OK without a mask because they don’t mind if you walk around with your face uncovered.Then, perhaps, there’s MAPH as in masks are preferred here. You don’t necessarily have to wear a mask, as you might on, say, a commercial airliner, but you would make the owners of the establishment happy and feel safer if you did.

In the world of politics, President Joe Biden (D) merits his own set of acronyms. If you think he’s bringing back civility, you might appreciate the chance to tell someone that you believe BMAC, for Biden makes America civil.

Now, of course, Biden, as with his predecessor, has numerous detractors. The New York Post is as eager to capture his daily verbal stumbles as the left-leaning papers and news organizations were to seize on former President Donald Trump’s (R) “covfefe” and other scrambled words. In that case, you might see Biden as a PINOE, as in a president in need of an editor, or a PINOC, as in a president in need of a compass.

Trump deserves his own set of acronyms. Borrowing from the redundant wording of the movie “Dodgeball: A True Underdog Story” (2004), supporters of the 45th president might say TIARA, as in Trump is always right, always.

Those who find the former president slightly off kilter, however, might believe he has a FANTS problem, as in facts are not Trump’s strength.

TOSID seems appropriate for both sides. That one stands for the other side is deceptive. That applies to Democrats and Republicans, each of whom sometimes reflexively suggest that the other side can’t possibly be honest because, if they were, the argument they’d like to make isn’t as powerful.

In the wonderful world of summer weather, how about HEFY, as in hot enough for you, or perhaps, CIRN, as in can’t it rain now?

Yankee fans are probably bracing for another mediocre, at best, half of the baseball year. Sure, we have talent, and we get periodic glimpses of adequacy, but we wind up looking like a fourth-place team. I have the feeling it’s NOY or not our year.

Parents have spent almost two years struggling with child care, education and their sanity amid a pandemic that has caused their children to become more like home-based barnacles than school-based students. To that end, and you can pronounce this one however you’d like, how about FCTKSIS, for fingers crossed to keep school in session?

Children, of course, couldn’t control whether their schools opened, which left them even more powerless to act out against the rules, tests or social pressures that follow them around like Pigpen’s dust storm from the Charlie Brown comics. They are now struggling with the need to EFTEW, or to emerge from the electronic world.

Many of us made normal hygiene habits optional. These days, we should consider recommending a SMIYL to our friends, as in a shower might improve your life.

While disconnecting during a phone call, turning off our video momentarily or covering our computer camera were options from home, we sometimes find ourselves stuck in conversations or interactions that aren’t working for us. We might need to beg someone to SAM or stop annoying me.

POSING IN POQUOTT

Daniel Dunaief discovered this frog friend on an evening walk with the dog in Poquott last week. He writes, ‘The frog, and the dog, stayed still long enough to allow us to get a close up using a phone light on one side and a camera on the other. After the photo, the dog ambled home and the frog hopped away.

Rain can put a damper on life, as the two children at the beginning of Dr. Seuss’s The Cat in the Hat shared and as the itsy bitsy spider that went up the water spout only to get washed out again discovered.

As it turns out, rain, clouds, wind and foul weather can reduce the trading decisions of people who buy and sell large sums of money in stocks, as they grapple with their own reactions to clouds that they’d like to go away and come again some other day.

Danling Jiang

Danling Jiang, associate dean of research and faculty development in Stony Brook University’s College of Business; Lin Sun, Assistant Professor at George Mason University; and Dylan Norris, Assistant Professor at Troy University recently published a study in which they explored the effect of cloudy or inclement weather in the two weeks before an earnings surprise on investor reactions.

Every three months, public companies provide a detailed disclosure of their profits and losses, giving investors a chance to look over the equivalent of a quarterly report card.

Like helicopter parents who monitor every line, sentence and word in a report card, institutional investors tend to have a stronger reaction, either positively or negatively, if those numbers are considerably different than they expected. An “A” in advanced calculus might be like profits that exceed estimates by 10 percent, while a “C” might be the equivalent of an unexpected loss in a business that had been doing well.

As it turns out, institutional investors are less likely to react as strongly, at least initially, to an earnings surprise if the skies in the two weeks before they review the earnings announcements are cloudy or unpleasant.

“We find strong supporting evidence in our empirical tests which reveal increases in the pre-announcement unpleasant weather of institutional investors results in muted immediate market responses to earnings news and amplified port-earnings-announcement drifts,” Jiang explained in an email.

Over the course of two to three months, the stock price reflects a more typical pattern that aligns with the direction of the earnings surprise.

The researchers published their work in the Journal of Corporate Finance.

These results, which came from an analysis of reactions to earnings surprises from 1990 to 2016, validate and extend previous efforts to understand how weather affects investor decisions.

Earlier studies revealed the effects of weather on individuals’ psychological and physiological states, according to Jiang.

“These effects have also been shown to influence financial decisions and security prices, even through the actions of sophisticated market participants such as market makers and security analysts,” she said.

The three academics started working together when Lin and Jiang were faculty and Norris was a PhD student at Florida State University.

“We were fascinated by the idea present in prior research that weather seems a perfect exogenous shock to investor psychology and physiology,” said Jiang. “This exogenous feature allows us to draw some causality of psychology on market pricing in a new setting with institutional investors and earnings announcements.”

The researchers chose the years 1990 to 2016 because they had the data in their possession.

“We tried to ensure that our sample period was long enough to confirm the weather effect was a persistent force throughout time and not merely a phenomenon of a small segment in time,” said Jiang who added that solving the weather-related muted effect by adding brighter lights to a trading floor could backfire, as excessive bright lights can have negative effects.

“Overillumination can cause fatigue, stress and anxiety,” she explained. “It is also likely that most traders are subject to the weather at some point during the day” through arriving at work, leaving for lunch or glancing out the window. That means the weather still likely influences them even when they may be in a brightly-lit indoor setting.

The researchers used two measures of weather conditions. One integrated wind, cloud and rain, and the other used cloud cover only. Both measures produced similar findings.

Using earlier studies and their own research, it appears accounting for the combined effect of simultaneous weather parameters or focusing on cloud cover better captures any physiological or psychological effects as opposed to using wind or rain alone, said Jiang.

Public companies are unlikely to trigger a more muted response to earnings surprises by recruiting investors from areas with greater cloud cover, as prior research demonstrated that seasonal climate norms don’t appear to affect the behavior of investors once they acclimate, so to speak, to the weather.

In addition to the 14-day window to create the weather measures, the researchers generated a seven-day measure that showed similar results.

Announcement day weather may also affect market reactions to earnings news and “we do not discredit its importance,” Jiang said. Indeed, other research has shown that the weather in New York City at the time of an earnings announcement impacts market reactions.

The explanation for the muted reaction to earnings is based on psychological and physiological reactions of institutional investors to weather, including anxiety and sadness as well as fatigue and decreased activity.

“In addition to causing delayed information processing, weather could cause a reduction in energy amongst some traders,” said Jiang

That means institutional investors may struggle with the same factors that made the boy and Sally from The Cat in the Hat struggle while it was “too wet to go out and too cold to play ball. So we sat in the house, we did nothing at all,” Dr. Seuss wrote.

While institutional investors don’t do nothing at all, they are less active, at least according to the recent research, than they are when the sun shines brightly, reliably and more consistently.

This past week, I spent more time personally and professionally speaking with other people than I had in over a year.

I give myself mixed reviews. Two anecdotes capture the range of my experiences. During one meeting, my brain had its own mini dialog, even as I tried to stay focused on details about a story I was researching. Here’s a sample of that internal dialog:

Wait, why is he looking away? Should I not have had that salad earlier? Do I have something green in my teeth?

No, hold on, maybe it’s that you’re tired and your eyes are closing. Open your eyes wider to indicate that you’re paying attention. No. NO. NO! Too wide! Now, he’s wondering why you’re staring so intently at him.

Okay, he’s looking at you again. Oh, no, I have to scratch my face. What do I do? Ignore it. Yes, that’s working. No, it’s not. Now, my face itches even more. Come on face, suck it up. No, I have to scratch. Maybe I can coordinate the scratch with the moment when he looks away. Come on, look away!

Great, now he’s looking at me without blinking, like Jack Nicholson in “A Few Good Men.” Wait, I’m listening. Really, I am, but I’m a tad distracted. It’s not my fault. It’s my face’s fault. 

I’m focused. I have a good question ready, but I still need to scratch my face. Look away. LOOK a-WAY! It’s not working. Instead of scratching, I’m twitching. Now he’s staring at the part of my face that itches and twitches.

I’m going to lean on my hand and scratch subtly, while listening intently and making solid, but not scary eye contact.

Okay, so, maybe that was a slight exaggeration, but it was an imperfect and slightly distracted moment in the real world.

Later in the week, I had another opportunity to multitask. Just as I started walking across a courtyard to a meeting, it started pouring.

I walked quickly. Running didn’t seem like a great choice because panting, dripping and sweating is never a good look for me.

When I arrived, an incredibly supportive executive assistant asked me if I wanted a hot tea, coffee, towel or water. I said I’d be fine.

Once I got in the office, I immediately realized, dripping onto, into and around the chair of one of my favorite sources, that his air conditioning was among the strongest in the area. In addition to the cool air in the room, I felt a slight breeze, which made me feel as if each droplet of water clinging to me might soon turn to ice.

As I spoke to him, rocking slightly back and forth, putting my hands under my legs to keep them warm, I was well aware of how ridiculous I must have looked. At the same time, I appreciated the in-person nature of the experience, which wasn’t an option six months earlier.

I enjoyed how the multitasking necessary to stay on track was so much different than the challenges of Zoom, where my primary concerns were whether the background in the screen included messy clothing, whether I was looking at the right place on the screen, and whether my dog would decide to bark at the five-year-old learning to ride a bike in front of our house.

Venturing further out than I have in over a year from the turtle-shell life felt like stepping back into a familiar but altered role. Despite the momentary and awkward setbacks, it was a welcome return to a three-dimensional world.

Cold Spring Harbor Laboratory’s DNA Learning Center and the Red Cloud Indian School recently launched a program called Students Talk Science in which high school students could ask questions from several senior scientists about the vaccine for COVID-19 and healthcare disparities in minority communities.

Dr. Eliseo Pérez-Stable

 

The talks are a component of a program called STARS, for Science, Technology & Research Scholars, an effort the group started in 2019 to build interest and experience in STEM for minority students. The Students Talk Science program engaged the STARS participants and students from the Red Cloud Indian School on the Pine Ridge Indian Reservation.

Jason Williams, Assistant Director of Inclusion and Research Readiness at the DNA Learning at CSHL; Brittany Johnson, an educator at the DNA Learning Center; Katie Montez, a teacher at the Red Cloud Indian School ;and Carol Carter, Professor in the Department of Microbiology and Immunology at the Renaissance School of Medicine at Stony Brook University, wanted to connect minority students with practicing physicians and scientists in leadership positions at the National Institutes of Health to allow them to ask questions of concern regarding the vaccines.

Dr. Monica Webb-Hooper

“We did this to empower them to function as trusted resources for their families, friends and network,” Carter, who participated as an individual rather than as a formal representative of Stony Brook University, explained in an email.

The conversations included interactions with Dr. Eliseo Pérez-Stable, Director of the National Institute on Minority Health and Health Disparities, or NIMHD at the National Institutes of Health; Dr. Monica Webb Hooper, Deputy Director of the NIMHD; Dr. Gary Gibbons, Director of the National Heat, Lung and Blood Institute; and Dr. Eugenia South, Assistant Professor in Emergency Medicine at the Hospital of the University of Pennsylvania and the Presbyterian Medical Center of Philadelphia.

The high school students prepared informed questions.

Dr. Gary Gibbons

“The students were encouraged to do their own research” on the interview subjects, Williams explained. “We asked students not to look just at [each] interviewee’s science work, but also any personal background/ biography they could find. Students had multiple opportunities for follow up and were largely independent on their choices of questions.”

Samantha Gonzalez, a student at Walter G. O’Connell Copiague High School, asked South about her initial skepticism for the vaccine.

South acknowledged that she had no interest in taking the vaccine when she first learned she was eligible. “I almost surprised myself with the fierceness with which I said, ‘No,’” South said. “I had to step back and say, ‘Why did I have this reaction?’”

Some of the reasons had to do with mistrust, which includes her own experiences and the experiences of her patients, whom she said have had to confront racism in health care. In addition, she was unsure of the speed at which the vaccine was developed. She had never heard of the mRNA technology that made the vaccines from Moderna and Pfizer/ BioNTech possible.

“I had to do my own research to understand that this wasn’t a new technology,” she said.

Dr. Eugenia South

South went through a learning process, in which she read information and talked to experts. After she received answers to her questions and with the urging of her mother, she decided to get the vaccine.

“I’m so thankful that I was able to do that,” South said.

The team behind Students Talk Science not only wanted to empower students to make informed decisions, but also wanted to give them the opportunity to interact with scientists who might serve as personal and professional role models, providing a pathway of information and access that developed amid an extraordinary period.

“We wanted to engage high school students in something unique going on in their lifetime,” Carter said.

To be sure, Carter and Williams said the scientific interactions weren’t designed to convince students to take the vaccine or to urge their parents or families to get a shot. Rather, they wanted to provide an opportunity for students to ask questions and gather information.

“We purposely did not participate in the discussions because our goal was not to convince or ‘preach,’ but to enable students and their networks to make informed decisions,” Carter said.

Parents had to read and sign off on the process for students to participate. The organizers didn’t want a situation where they were doing something that conflicts with a parents’ decisions or views.

Williams added that the purpose of the conversations was never to say, “you must get the vaccine. Our purpose is to talk about information.”

The objective of these interactions is to help minority students find a track for a productive career in ten years.

In addition to questions about hesitancy, Williams said some of the high school students expressed concerns about access to vaccines. He is pleased with the result of this effort to connect students with scientists and doctors.

The group was “able to get some of the most important scientists in the country to sit with high school students,” he said. “It was very powerful to give students access to these role models.”

The goal is to stay with these students, mentor them and stay in touch with them until they graduate from college and, perhaps, return as research scientists.

Even for students who do not return, this type of interaction could provide an “impactful experience that prepares them for other opportunities,” Williams explained, adding that the STARS program would incorporate the Students Talk Science Series into the program more formally in the future, with new students and topics most likely during the school year.

Detectives often look for the smallest clue that links a culprit to a crime. A fingerprint on the frame of a stolen Picasso painting, a shoe print from a outside a window of a house that was robbed or a blood sample can provide the kind of forensic evidence that helps police and, eventually, district attorneys track and convict criminals.

The same process holds true in the world of disease detection. Researchers hope to use small and, ideally, noninvasive clues that will provide a diagnosis, enabling scientists and doctors to link symptoms to the molecular markers of a disease and, ultimately, to an effective remedy for these culprits that rob families of precious time with their relatives.

For years, Ken Shroyer, the Marvin Kuschner Professor and Chair of Pathology at the Renaissance School of Medicine at Stony Brook University, has been working with a protein called keratin 17.

A part of embryological development, keratin 17 was, at first, like a witness who appeared at the scene of one crime after another. The presence of this specific protein, which is unusual in adults, appeared to be something of a fluke.

Until it wasn’t.

Shroyer and a former member of his lab, Luisa Escobar-Hoyos, who is now an Assistant Professor at Yale, recently published two papers that build on their previous work with this protein. One paper, which was published in Cancer Cytopathology, links the protein to pancreatic cancer. The other, published in the American Journal of Clinical Pathology, provides a potentially easier way to diagnose bladder cancer, or urothelial carcinoma.

Each paper suggests that, like an abundance of suspicious fingerprints at the crime scene, the presence of keratin 17 can, and likely does, have diagnostic relevance.

Pancreatic cancer

A particularly nettlesome disease, pancreatic cancer, which researchers at Stony Brook and Cold Spring Harbor Laboratory, including CSHL Cancer Center Director David Tuveson, have been studying for years, has a poor prognosis upon diagnosis.

During a process called surgical resection, doctors have been able to determine the virulence of pancreatic cancer by looking at a larger number of cells.

Shroyer and Escobar Hoyos, however, used a needle biopsy, in which they took considerably fewer cells, to see whether they could develop a k17 score that would correlate with the most aggressive subtype of the cancer.

“We took cases that had been evaluated by needle biopsy and then had a subsequent surgical resection to compare the two results,” Shroyer said. They were able to show that the “needle biopsy specimens gave results that were as useful as working with the whole tumor in predicting the survival of the patient.”

A needle biopsy, with a k17 score that reflects the virulence of cancer, could be especially helpful with those cancers for which a patient is not a candidate for a surgical resection.“That makes this type of analysis available to any patient with a diagnosis of pancreatic cancer, rather than limiting it to the small subset of cases that are able to undergo surgery,” Shroyer said. 

Ultimately, however, a k17 score is not the goal for the chairman of the pathology department.

Indeed, Shroyer would like to use that score as a biomarker that could differentiate patient subtypes, enabling doctors to determine a therapy that would prove most reliable for different groups of people battling pancreatic cancer.

The recently published report establishes the foundation of whether it’s possible to detect and get meaningful conclusions from a needle biopsy in terms of treatment options.

At this point, Shroyer isn’t sure whether these results increase the potential clinical benefit of a needle biopsy.

“Although this paper supports that hypothesis, we are not prepared yet to use k17 to guide clinical decision making,” Shroyer said.

Bladder cancer

Each year, doctors and hospitals diagnose about 81,000 cases of bladder cancer in the United States. The detection of this cancer can be difficult and expensive and often includes an invasive procedure.

Shroyer, however, developed a k17 protein test that is designed to provide a reliable diagnostic marker that labs can get from a urine sample, which is often part of an annual physical exam.

The problem with bladder cancer cytopathology is that the sensitivity and specificity aren’t high enough. Cells sometimes appear suggestive or indeterminate when the patient doesn’t have cancer.

“There has been interest in finding biomarkers to improve diagnostic accuracy,” Shroyer said. 

Shroyer applied for patent protection for a k17 assay he developed through the Stony Brook Technology Transfer office and is working with KDx Diagnostics. The work builds on “previous observations that k17 detects bladder cancer in biopsies,” Shroyer said. He reported a “high level of sensitivity and specificity” that went beyond that with other biomarkers.

Indeed, in urine tests of 36 cases confirmed by biopsy, 35 showed elevated levels of the protein.

KDx, a start up biotechnology company that has a license with The Research Foundation for The State University of New York, is developing the test commercially.

The Food and Drug Administration gave KDx a breakthrough device designation for its assay test for k17.

Additionally, such a test could reveal whether bladder cancer that appears to be in remission may have recurred.

This type of test could help doctors with the initial diagnosis and with follow up efforts, Shroyer said.“Do patients have bladder cancer, yes or no?” he asked. “The tools are not entirely accurate. We want to be able to give a more accurate answer to that pretty simple question.”
