If sweat were a valuable commodity, I’d be in high demand.

As it is, however, my thick, heavy high-volume sweat is as welcome as a cup of warm water on a hot, sticky day.

When I was a teenager and attended basketball camp, I used to sit in the back seat with two other campers, squeezing my thick thighs together as much as possible to avoid sharing the sweat that coated my legs.

I had and continue to have the kind of sweat glands that would give marathoners from Ethiopia a run for their money.

No, I can’t run as far or as fast as a marathon runner, but I still sometimes looked like one, especially on those summer days when I walked a few miles to work and arrived in a puddle-stained suit.

Fortunately, the public, even before the notion of “fake news” became trendy, rarely had high expectations for the attire of a reporter.

When the temperature and humidity are high enough, I can picture the various characters from the Disney/Pixar movie “Inside Out” pushing and shoving as they try to climb into a small raft in a sweat-drenched control room.

The process almost always starts on my upper lip. That’s where beady sweat scouts come out, checking to see if it is indeed worth alerting the rest of my body that it’s a good time to join the fun.

Within seconds, my arms and wrists have the almost modest effect of glistening, as a thin layer of perspiration can catch the sun at just the right angle, giving my skin a mildly reflective look. After a few short moments, the production line kicks into higher gear. My fingers, which often swell when I walk more than a mile or so, become drenched.

I have had a few occasions when I’ve run into people who introduce me to others in this condition. When they stick out their hands to shake mine, I’m stuck.

While holding my hand back is disrespectful, soaking someone I’ve met with a soggy handshake makes the wrong kind of first impression.

My sister-in-law carries a collection of mostly healthy snacks in her purse for when my typically charming and delightful brother enters the hangry stage of the day and needs food to carry him to the next meal.

I don’t often become frustrated or angry when I’m hungry. I do, however, become embarrassed when I can feel the thick, heavy drops of sweat racing down my back, slaloming down my legs and collecting in my shoes.

Maybe I should suggest to my wife that she carry wipes, paper towels, an electric fan, or a magical towel that comes out of a tiny purse but can absorb a full day’s worth of sweat. I bet Mary Poppins could pull that off.

Since I’m not always with my wife and this isn’t her problem, I rub my hands against my legs. That kind of works, although that then leaves a soaked hand print on the outside of my pant leg which is usually met by the layer of moisture accumulating on the inside of my pants.

Now, dry fit shirts have become a true gift for me, as they don’t immediately become drenched with perspiration. Maybe some day someone will invent a dry fit suit, which looks like normal business attire, but doesn’t become a magnet for moisture.

I know astronauts drink a purified form of urine, the moisture they exhale and their own sweat. When I interviewed Astronaut Scott Kelly several years ago, he mentioned that he particularly enjoyed the taste of the purified water aboard the International Space Station, where he lived for 340 straight days.

I suppose that means I’d be a valuable commodity as an older, slower moving astronaut, assuming that I didn’t need to drink every ounce and then some, of what I produced when I sweat.

Oh well, that probably won’t work and I’m not that eager to travel into space. In the spirit of reduce, reuse, recycle, maybe I should figure out how to turn my own sweat into an icy cold drink.

For many young children, the ideal peanut butter and jelly sandwich doesn’t include any crust, as an accommodating parent will trim off the unwanted parts before packing a lunch for that day.

Similarly, the genetic machinery that takes an RNA blueprint and turns it into proteins includes a so-called “spliceosome,” which cuts out the unwanted bits of genetic material, called introns, and pulls together exons.

When the machinery works correctly, cells produce proteins important in routine metabolism and everyday function. When it doesn’t function correctly, people can contract diseases.

Danilo Segovia, a PhD student at Stony Brook University who has been working in the laboratory of Cold Spring Harbor Laboratory Professor Adrian Krainer for seven years, recently published a study in the Proceedings of the National Academy of Sciences about an important partner, called DDX23, that works with the key protein SRSF1 in the spliceosome.

“We obtained new insights into the splicing process,” said Krainer, who is the co-leader of the Gene Regulation & Inheritance program in the Cancer Center at CSHL. “The spliceosome is clearly important for every gene that has introns and every cell type that can have mutations.”

Krainer’s lab has worked with the regulator protein SRSF1 since 1990. Building on the extensive work he and members of his lab performed, Krainer was able to develop an effective treatment for Spinal Muscular Atrophy, which is a progressive disease that impacts the muscles used for breathing, eating, crawling and walking.

In children with SMA, Krainer created an antisense oligonucleotide, which enables the production of a key protein at a back up gene through more efficient splicing. The treatment, which is one of three on the market, has changed the prognosis for people with SMA.

At this point, the way DDX23 and SRSF1 work together is unclear, but the connection is likely important to prepare the spliceosome to do the important work of reading RNA sequences and assembling proteins.

Needle in a protein haystack

Thanks to the work of Krainer and others, scientists knew that SRSF1 performed an important regulatory role in the spliceosome.

What they didn’t know, however, was how other protein worked together with this regulator to keep the machinery on track.

Using a new screening technology developed in other labs that enabled Segovia to see proteins that come in proximity with or interact with SRSF1, he came up with a list of 190 potential candidates.

Through a lengthy and detailed set of experiments, Segovia screened around 30 potential proteins that might play a role in the spliceosome.

One experiment after another enabled him to check proteins off the list, the way prospective college students who visit a school that is too hilly, too close to a city, too far from a city, or too cold in the winter do amid an intense selection process.

Then, on Feb. 15 of last year, about six years after he started his work in Krainer’s lab, Segovia had a eureka moment.

“After doing the PhD for so long, you get that result you were waiting for,” Segovia recalled.

The PhD candidate didn’t tell anyone at first because he wanted to be sure the interaction between the proteins was relevant and real.

“Lucky for us, the story makes sense,” Segovia said.

Krainer appreciated Segovia’s perseverance and patience as well as his willingness to help other members of his lab with structural work.

Krainer described Segovia as the “resident structural expert who would help everybody else who needed to get that insight.”

Krainer suggested that each of these factors had been studied separately in the process, without the realization that they work together.

This is the beginning of the story, as numerous questions remain.

“We reported this interaction and now we have to try to understand its implications,” said Krainer. “How is it driving or contributing to splice assembly.”

Other factors also likely play an important role in this process as well.

Krainer explained that Segovia’s workflow allowed him to prioritize interacting proteins for further study. Krainer expects that many of the others on the list are worth further analysis.

At some point, Krainer’s lab or others will also work to crystallize the combination of these proteins as the structure of such units often reveals details about how these pieces function.

Segovia and Krainer worked together with Cold Spring Harbor Laboratory Professor Leemor Joshua-Tor, who does considerably more biochemistry work in her research than the members of Krainer’s lab.

When a cowboy met a witch

A native of Montevideo, Uruguay, Segovia came to Stony Brook in part because he was conducting research on the gene P53, which is often mutated in forms of human cancer.

Segovia had read the research of Ute Moll, Endowed Renaissance Professor of Cancer Biology at Stony Brook University, who had conducted important P53 research.

“I really liked the paper she did,” said Segovia. “When I was applying for college in the United States for my PhD, I decided I’m for sure going to apply to Stony Brook.”

Even though Segovia hasn’t met Moll, he has benefited from his journey to Long Island.

During rotations at CSHL, Segovia realized he wanted to work with RNA. He found a scientific connection as well as a cultural one when he discovered that Krainer is from the same city in Uruguay.

Krainer said his lab has had a wide range of international researchers, with as many as 25 countries represented. “The whole institution is like that. People who go into science are naturally curious about a lot of things, including cultures.”

Segovia not only found a productive setting in which to conduct his PhD research, but also met his wife Polona Šafarič Tepeš, a former researcher at Cold Spring Harbor Laboratory who currently works at the Feinstein Institute for Medical Research. Tepeš is originally from Slovenia.

The couple met at a Halloween party, where Segovia came as a cowboy and Tepeš dressed as a witch. They eloped on November 6, 2020 and were the first couple married after the Covid lockdown at the town hall in Portland, Maine.

Outside of the lab, Segovia enjoys playing the clarinet, which he has been doing since he was 11.

As for science, Segovia grew up enjoying superhero movies that involve mutations and had considered careers as a musician, scientist or detective.

“Science is universal,” he said. “You can work wherever you want in the world. I knew I wanted to travel, so it all worked out.”

As for the next steps, after Segovia defends his thesis in July, he is considering doing post doctoral research or joining a biotechnology company.

Catch a screening of 'The Candidate' on July 12.
Update: The event on July 10 has been postponed to October 7.

By Daniel Dunaief

Films can take us far from our lives, even as they can also bring us closer to truths about our world.

From July 9 to 12, the Cinema Arts Centre, 423 Park Ave., Huntington is presenting a four-day festival that highlights the intersection between politics and Hollywood. The screenings, which cost $16 for nonmembers and $10 for members, will include the films Mr. Smith Goes to Washington, The Best Man, and The Candidate.

On the first night, former Congressman and the festival’s curator Steve Israel will host a discussion entitled “Campaigning on Celluloid: How Cinema Informs and Reflects Changing Political Communication on Film.”

Israel, who taught a class at Cornell University about politics and film after he left public office, selected the movies.

‘Mr. Smith Goes to Washington’ will be screened on July 10.

“I thought it would be interesting and fun to offer a similar series” to the films he discussed at Cornell “on Long Island to the general public,” he said.

Israel describes the film The Best Man, which pits the principled William Russell, played by Henry Fonda, against the populist opportunist Joe Cantwell, acted by Cliff Robertson, as eerily prescient of recent political battles.

“It’s an example of a film in 1964 that was regarded as entertaining and implausible that has been overtaken by the reality,” said Israel.

The Cinema Arts Centre is debuting this series of movies this year and may run another similar program in future years.

Israel anticipates a discussion about how films are a “projection of our times and politics often influences films,” and added that some films seem political, but they aren’t, while others don’t seem political, but they are.

‘The Best Man’ will be screened on July 11.

“We are going to explore that dynamic,” Israel explained.

Atticus Finch, the hero in Harper Lee’s novel To Kill a Mockingbird, served as a role model for Israel, who spent his early time in public service trying to emulate the determined lawyer. “Atticus Finch wouldn’t survive in our current political environment,” Israel said.

The novel is relevant in the world of today, as a modern day Finch would struggle to confront the anger, vitriol and division that defines contemporary society, Israel suggested.

The reality of the modern political environment has surpassed the fiction, making the two satirical novels Israel has written difficult to produce.

“The market for satire is dead because the reality has surpassed the story,” Israel added. 

Non partisan

Nate Close, the Director of Marketing and Communications at the Cinema Arts Centre, explained that the mission of the festival is to be nonpartisan.

Indeed, guest speakers come from both parties, with republican Representative Peter King joining Israel for a discussion after Mr. Smith Goes to Washington and political strategist and policy advisor Basil Smikle participating in the post discussion after The Candidate.

The festival hopes to “shine a light on how these two institutions [politics and Hollywood] influence American culture and shape each other,” said Close. “There’s interplay there.”

Films are “more important than ever,” said Israel. “You sit through it, you take in the textures, the characters and the writing” and it “should inspire us to think.

Program Schedule:

Tuesday, July 9 at 7:30 p.m.

Campaigning on Celluloid: How Cinema Informs and Reflects Changing Political Communication on Screen — Lecture with former Congressman Steve Israel

*Postponed to October 7: Wednesday, July 10 at 7 p.m.

At shorter distances, she can walk faster than some people can run in a sport she only entered over two years ago. Driven to succeed, Ruby Ray competed on a national stage this past weekend, trying for a spot on the U.S. Olympic Team heading to Paris next month in the 20 kilometer (or 12.4 mile) racewalk.

A graduate of Earl L. Vandermeulen High School in Port Jefferson, Ray, 19, didn’t make the team, finishing in 9th place at the Oregon trials on Saturday, with a time of one hour, 54 minutes and 15 seconds. That is an average of 9 minutes, 13 seconds per mile for the entire race.

Ray, who had swollen glands and a fever from a cold the morning of the competition, made it through the race, rising as high as fifth place at the 2500 meter mark before dropping back to ninth.

“It was a wonderful experience competing in person with the greatest athletes in the United States,” said Ray. “I was a little disappointed with my performance.”

While her coach Gary Westerfield, founder of WalkUSA, was also hoping for a better time, he appreciated her effort under difficult conditions.

“I give her a lot of credit,” said Westerfield. “She could have dropped out.”

Westerfield expects Ray, who is a rising sophomore at St. John’s University, to build on this experience as she takes aim at the 2028 Olympics in Los Angeles.

A life-changing request

Ray followed an unconventional path to the Olympic Trials.

An aspiring field hockey player, Ray was disappointed when the school no longer competed in the sport. Ray switched to Track and Field.

One day when Ray was in her junior year, Brian Snow, the head coach of the women’s varsity Track and Field team, asked if anyone would be willing to try race walking as a way to earn more points for the team.

After watching a video of a sport that receives considerably more attention in places like Ecuador, Mexico and China than it does in the United States, the five-foot, eight-inch Ray agreed to give it a try, race walking up and down the hallway of the school, impressing Snow enough to encourage her to prepare to compete in high school races.

“That first year, she did really well,” said Snow. “She really helped the team. She was able to score points in important meets.”

Ray was named the Athlete of the Year in 2022 by USA Track and Field in racewalking for competitors under 20.

Snow appreciated not only how much she improved, but also her willingness to step up for the school.

“If we needed someone in a relay, she would do it,” said Snow. 

The track coach recalled how Ray fainted during the school day. She went to the hospital to get checked out and then returned for the rest of the day. Ray volunteered to participate in the meet, but Snow opted against allowing her to race.

“She cheered on the team,” he said. “She put the team first. Her teammates always knew she was destined for greater things.”

In her first year of track, Ray was race walking at an event. Westerfield, a track official at the competition who is an accomplished racewalker and coach, asked her parents if he could start working with her. 

Intense focus

An accomplished race walker who has only been in the field for two years, Ray brings a discipline and focus to a wide range of challenges.

Like her mother Madeleine Kristoffersson, who is an accomplished opera singer, Ray has put her vocal skills to work, joining the church at St. John’s as a cantor.

Ray has dual citizenship between the United States and Sweden, where her mother was born and raised.

Ray was also an equestrian. When COVID-19 shut down some of the events, she poured her energy into track.

When Ray started to compete in race walking, her mother knew about the event.

“In Sweden, that is a huge sport,” she said. “I have seen this from childhood and knew what it was. She looked like the people I had seen walking” in races.

Ray has received considerable help and encouragement from her parents. She trains twice a week with Westerfield. On the other days, her mother has gone with her to the track, recognizing when her daughter needs water or when she’s having a tough day.

“I live and breathe this with her,” said Kristoffersson, who traveled with Ray to Oregon for the Olympic trials.

A country commitment

For Ray and her parents, representing the country at the Olympics would be a significant honor.

Being the parent of an Olympian “would be the most wonderful experience I could ever have had,” said John Ray, Ruby’s father, who has a law practice in Miller Place. “I love my country. She grew up to love her country. She feels like she’s representing Port Jefferson and Long Island in the trials.”

Ray’s father, who suggests his singing skills are limited to the shower, has his own athletic pedigree, having played lacrosse for the last 58 years, including as a goalie on teams with men considerably younger than he.

Ray herself felt like being a part of the Olympics would be “incredible” and that she would be representing Long Island, Port Jefferson, Suffolk County, and “all the things I love. I would be showcasing it off to the world in the Olympics.”

In addition to contributing to her country with her athletic skills, Ray also joined the Reserve Officers’ Training Corp at St. John’s in the Army Rangers Program.

“My family has a long history in the military,” said Ray. “It’s a great honor to fight for your country and then come back and your family and county are proud of you.”

Ray regularly wakes up at 4:30 am for Ranger training. She has scars on her knees from crawling across the ground and bruises on her back from hiking with a heavy backpack.

“You have to stay dedicated,” she said. “You have to be willing to do what is required.”

She has had to sacrifice some time with friends, while avoiding temptations that might derail her athletic or academic goals as well as her ROTC training.

Ray is in the English Honors program at St. John’s, where she has a full scholarship.

While Ray is talented and focused, she shared a few guilty pleasures, which include dark chocolate Reese’s peanut butter cups, ice cream and cheesy popcorn.

Ray has three goals in mind. She’d like to make the Olympic team in 2028 and win a gold medal in Los Angeles, she’d like to make the track team at St. John’s, likely competing in the 5K running race, and she’d like to join the Judge Advocate General.

“I want to help people buried under the system,” said Ray, who participates in her father’s pro bono work. “My dad puts his heart into his effort and I want to do the same, especially in the military for people who fought for our country and deserve support.”

People who have known Ray for years wouldn’t bet against this determined teenager.

Ray will “do some amazing things in her life, regardless of what happens with race walking,” said Snow.

Ray reflected positively on her experience in Oregon.

“I was just astonished by the fact that we were there” at the trials, she said. “This new experience has given me hope to grow stronger.”

Our senses are such an exquisite gift, at any time of the year.

During the summer on Long Island, we can close our eyes, which is home to our most dominant sense, and breathe in the other stimuli.

For me, the sounds of summer form a symphony, with notes coming from nearly every part of my imagined orchestra.

First, the water and everything on and around it reminds us of the pageantry of the island.

The regular horn from the Port Jefferson/ Bridgeport Ferry warns other boats of its movements even as the horn carries great distances.

The summer surf, which can be so variable, can offer a calming, rhythmic shushing sound, as the water laps on the shore or slowly feels its way up the rocks.

With stronger winds or a storm brewing in the Atlantic, those same waves can crash down more violently, as if someone put an amplifier along the beach. Instead of offering a peaceful shush, they provide more of a vibrating symbol, announcing their presence on shore, pulling rocks and sand back out to the ocean amid a more violent undertow.

Then, of course, there is the welcome sound of merriment coming from the water, with children squealing with delight as they play “Marco Polo,” race back and forth in a pool, splash each other, or have chicken fights.

Often at the beaches, the slow progression of an ice cream truck, playing “The Entertainer” or some other redundant musical variant, calls to parents and adults, luring us with cold sweets to offset hot days.

Depending on where you walk, drive, or bicycle, you might also hear the sound of a well struck tennis ball or the disappointed grunt or unprintable word that follows a missed volley, a double fault, or a backhand that sailed long.

Growing up, I was part of a sailing family. In addition to the constant chewing sound that came from the nonstop floating meals, we also heard the fluttering and unfurling of a sail, the regular crashing and splashing of the boat on the waves, and the sudden and frantic maneuvers of passengers on a boat that’s heading into shallow water or towards another vessel.

All manner of birds call to each other from the trees, with the familiar tweet, tweet, screeeeech coming from red-winged blackbirds who always seem to be trying to one-up each other with their aggressive squawking.

Our noses also become more active during the summer, as we can smell the salt water even before we round that last turn on the way to the beach. We can also enjoy the scent of mouth-watering Fourth of July barbecues or, perhaps, the smell of late night s’mores.

Those of us fascinated and delighted by the weather also might catch the scent of an approaching rain storm before the first drops arrive, as the sudden change in humidity or cooler air serves as a preamble for approaching precipitation.

Speaking of cooler, our skin, which we, of course, should protect during the brighter and longer days of summer, can also partake in a wide range of experiences.

For starters, we can cool off during the unbearably hot days by diving into a cool pool or running through the surf and plunging below the surface.

After we take long walks along a hot path, we can enter a heavily air conditioned room, where we might consider grabbing a long-sleeved tee shirt or a light sweatshirt despite the searing outdoor heat.

The tastes of summer also sweeten the season, with fresh fruit and pies serving as the finale to a satisfying meal.

Even without looking at the fireworks, we can appreciate the percussive cadence of these exploding colors. We can hear the long whistle of fireworks hissing their way against gravity, until they explode into a shower of sparklers. As the fireworks celebrations build, we can hear the more rapid explosions, which typically conclude with loud, rapid sounds whose echoes sometimes interfere or amplify the boom from the next set of entertaining sights and sounds.

Then, of course, we can enjoy the wide range of colorful light that uses our homes and neighborhoods as a posterboard, enabling even mundane speed limit signs to irradiate with oranges, yellows and reds.

The dinosaur family tree has few members in Zimbabwe, as only four fossils have been found in the region.

Kimberley Chapelle

Recently, researchers from several universities, including Kimberley “Kimi” Chapelle, Assistant Professor in the Department of Anatomical Sciences in the Renaissance School of Medicine at Stony Brook University, described a new species of dinosaur from a 210 million year-old fossilized hind leg in the journal Acta Palaeontologica Polonica.

Reconstructing the entire dinosaur from the bones they discovered in Lake Kariba, the scientists, led by Paul Barrett from the Natural History Museum of London, estimated that this plant-eating sauropodomorph weighed about 850 pounds and was among the larger dinosaurs in the late Triassic period.

The first new dinosaur species described in the Mid-Zambezi Basin of Northern Zimbabwe in more than 50 years, the sauropodomorph survived a mass extinction event that wiped out about 76 percent of all terrestrial and marine creatures. The sauropodomoprh group includes animals like the enormous Brontosaurus, which came later in the evolution of the lineage. Chapelle was on the field expedition in 2017 when Barrett noticed the fossil sticking out of the ground.

The discovery was “extremely exciting, as there was a high chance it was going to be something new,” said Chapelle. “It was well-preserved in articulation and we knew the bones came from the same individual.” She participated in the lengthy process that involved excavating the rare find, creating a reconstruction, isolating the bones to look at the structure, describing the fossil and comparing it to other, closely-related dinosaurs to determine where it sits on the family tree.

The researchers named this species Musankwa sanyatiensis, using the name of the houseboat Musankwa on which they lived and worked as they searched for fossils during the dry seasons around the man-made Lake Kariba.

“Musankwa is cool because it’s one of only a handful of dinosaurs from Zimbabwe, a country with amazing fossil resources that have yet to be fully discovered,” explained Jonah Choiniere, a Professor in the Evolutionary Studies Institute at the University of Witwatersrand in Johannesburg South Africa, who served as Chapelle’s PhD advisor. “Because we don’t have any specimens of Musankwa in similar-age rocks in South Africa, it tells us that during the Triassic period there might have been slightly different species groups of dinosaurs in the two countries.”

The Earth looked considerably different when this long-necked dinosaur was searching for its plant meal, as the land masses of the planet were combined in one supercontinent called Pangaea. In that time, Musankwa’s predators likely included meat-eating therapods and crocodile-like reptiles, which are ancestors of modern crocodiles.

Keep your head up

Hunting for fossils in Zimbabwe, which presented an opportunity for this kind of discovery, came with some challenges.

For starters, researchers lived aboard the houseboat Munsankwa, whose name in the Tongan dialect means “boy close to marriage.” Lake Kariba, which was created between 1958 and 1963 and is the largest artificial lake and reservoir by volume, gets “really hot in the summer and all you want to do is swim,” said Chapelle.

That, however, is ill-advised, as modern crocodiles roam the waters of the lake so regularly that people stay far from the shoreline.

To combat the heat, Chapelle drank plenty of water, applied regular sunscreen and wore large hats and long sleeves to keep the strong rays of the sun off her skin. Additionally, the researchers worked between morning and afternoon. The scientific expedition had an armed game ranger with them, to keep scientists safe.

“When you’re looking at fossils, you are always looking at the ground,” Chapelle said. At one point, she looked up and saw a hippo about 50 feet from her. “You have to remember to be aware of your surroundings,” she  said.

Field experience

Choiniere, who inspired his former student to consider entering the field when he first arrived at the University of Witwatersrand, saw Chapelle in action when she first did some field work.

Chapelle’s scientific curiosity never faltered, despite some significant field misadventures that included staying in a rotten old farmhouse without plumbing, sleeping in tents in the freezing cold in the backyard of a rural pub, hiking through brambles over the side of a mountain, and touring around Germany eating nothing but stewed cabbage and pork in brown sauce, and staying three to a hostel room to save money.

“In [Chapelle’s] case, there was never any doubt — she loved the field from day one and has never looked back,” Choiniere explained.

Choiniere believes Chapelle has a “unique skillset among paleontologists,” as her talents include math, observations of shape and structure, histology, three-dimensional data processing and field work. Beyond her diverse skills, Choiniere appreciated Chapelle’s time management skills and her pleasant demeanor, which enabled her to greet him with a smile even when he delivered his part later than she anticipated.

A promising LI start

Chapelle, who started working at Stony Brook at the end of January, is enjoying a return to New York. A native of Johannesburg, South Africa, she  had done a postdoctoral fellowship at the American Museum of Natural History in 2021.

A current resident of Rocky Point, Chapelle lives close to the beach. She and her husband Dominic Stratford, an Adjunct Professor at Stony Brook and Archaeologist and Associate Professor at the University of the Witwatersrand in Johannesburg, brought their Australian Shepherd named Shango with them.

A runner who recently completed the Shelter Island 10K and who loves taking pictures, Chapelle, who is the daughter of a doctor, originally thought she’d want to become a veterinarian. When she took a course in her third year of college with Choiniere, she was hooked by the link between evolution and anatomy.

As for the recent paper, Chapelle is pleased that people can read about this newly discovered dinosaur.

“This is years and years of work that gets put into this,” she said. “It also gives us a push to keep finding new things and publishing.”

The montage played in my mind even before I stepped out of the car at the Old Field Club last weekend. My father and older brother were pedaling ahead of me, too fast for my thick, stocky legs to keep pace. My younger brother and mother were behind me, too slow for my taste and my level of impatience.

“Pe-dal fa-ster,” I recalled grimacing through crooked, gritted teeth, hoping that I could hear whatever magic words my father and older brother were exchanging.

Pushing on a bicycle that didn’t have any gears and struggling against a wind that always seemed to be blowing in my face, I only caught up to them when they circled back. Determined as I was not to cut corners or shorten my ride, I reached the end of West Meadow Beach, stopped for a few seconds to rest my legs and restarted the pursuit.

I could also picture the numerous times I stood on the shore, searching for the perfect skimming rock, bringing a collection to the water’s edge and waiting my turn to try to send a rock far from shore.

More dramatic weather scenes also played in my head, as I pictured waves frozen in place by a prolonged stretch of cold weather. I’m sure I love winter beaches because of those moments when I felt like I owned the isolated sand sculpted by the same powerful wind whose fingers tried to reach through any holes in my coat or open air spaces to stab at exposed skin.

After heavy rainstorms, I recalled stopping on my ten-speed bike, staring at the flooded road that turned the road into a canal.

And then there was last Saturday, as I drove up to the entrance to the club, waiting for a valet to park my car and to celebrate the wedding of the son of a close friend and former coworker of my wife.

We entered the club, took our glass of champagne and made our way to the benches outside, where other people my wife knew greeted her and compared notes about the changes in their lives since they last saw each other.

While overlooking the water, we listened as my wife’s friend’s son, whom I recall seeing years earlier eating ice cream and “making memories,” exchanged vows each of them wrote to mark this incredible occasion. My wife’s friend’s son expressed his eagerness to start his own family.

I watched carefully as my wife’s friend had a perma-grin plastered on her ageless face, reveling in this couple that seemed to melt into each other’s arms for their first dance. The family I didn’t know at all also seemed pleased, albeit in a more buttoned down and restrained way, as they clapped for the happy couple.

Then, of course, the music, which served as a starter’s gun for my wife and me at these events, began, sending us vaulting out of our seats and onto the dance floor.

Life was so different for me now, as an appreciative guest for this loving event, but also for the world. People took out their cell phones to take pictures of this endless love, they exchanged cell phone numbers, and smiled at a camera atop a giant mirror on the dance floor that developed a sequence of photos.

Several grandparents enjoyed the celebration, beaming with pride at their children and grandchildren.

They likely had even more memories flooding through their mind than I, as they could recall the birth of their own children and grandchildren, with yet another magical turn of the time wheel to the next generation.

When these grandparents were considerably younger, they couldn’t have attended such a wedding, as the loving couple are both men. 

Here they were, supporting their grandson, who floated across the room with his husband and expressed his keen appreciation for the guests who came to celebrate this momentous day.

I wonder what ways the world might change between now and when we, if we’re fortunate enough, get to celebrate a similar event for future generations.

For me, that night was yet another memory on a familiar road that has served as the backdrop for my life’s journey. Even as I replay the celebration, I can hear the words of several ABBA songs, like “Gimme! Gimme! Gimme” and “Lay all your love on me.”

Typical sampling of ocean water excludes small microplastics which, as it turns out, are much more abundant even than larger pieces.

Luis Medina Faull

That’s the conclusion of a recent paper published in Marine Pollution Bulletin based on research conducted by Luis Medina Faull, Lecturer and IDEA Fellow, Sustainable Climate Justice and Solutions at the School of Marine and Atmospheric Sciences at Stony Brook University.

Using Raman microspectrometry to test ocean waters from the Caribbean to the Arctic, Medina Faull discovered smaller microplastics that were 10 to 100 times more abundant than the larger ones.

“We can’t see these plastics and, until recently, we couldn’t even track the samples,” said Medina Faul. “These small pieces can be easily ingested by marine organisms, such as fish” who translocate them into tissues where humans can consume them. “They are an emerging contaminant in our ocean so we have to be very concerned.”

Microplastics not only harm organisms that live in the ocean, but also create a health threat to humans, appearing in breast milk, heart muscles, blood, and waste products such as feces.

Microplastics can alter cell activity. The threat these particles pose to the environment and human health increases the urgency to understand this contaminant.

At this point, scientists don’t yet know how much of these microplastics fish have consumed although every species studied has evidence of microplastic ingestion.

Plankton nets can find microplastics that are between 300 and 500 micrometers or larger. Medina Faull, however, can detect microplastics that are 1 to 300 micrometers.

In samples taken from the Northeast Coast of Medina Faull’s native Venezuela, the Gulf Stream Current, which includes the Caribbean and Atlantic Ocean and the Pacific Arctic Ocean, the Stony Brook scientist found that the most abundant microplastics were between 1 and 14 micrometers, with 60 percent under 5 micrometers.

His findings exceeded previous combined reports about the abundance of these microplastics by six orders of magnitude.

While the larger particles of microplastics weighs more in the ocean, “it is important to measure the number of particles and their mass,” Medina Faull explained in an email, which will help “to understand the plastic budget in the ocean and the possible ecological or biological impact of these particles.”

The general public, government agencies and the scientific community have become increasingly concerned about microplastics. Medina Faull recently attended the first New York State Microplastics summit organized by the New York Department of Environmental Conservation and the State University of New York at Buffalo. They discussed the kind of microplastics thresholds that could be harmful to humans and the environment.

The challenges of small pieces

The primary ingredient in plastics, which are made from fossil fuels, is carbon, constituting about 70 to 90 percent of the material that creates packaging, coverings, wraps and other products.

Determining the origin and content of these microplastics, which are a collection of materials manufactured and sold in different countries, is challenging. Microplastics in the ocean come from mismanagement of solid waste, dumping, fisheries, tourism and other sources.

For the larger pieces of microplastics, which are still exponentially smaller than the eight-inch water bottle that people drink at baseball games and picnics, researchers can determine where the plastic was made.

For the smaller pieces, scientists can link materials to specific activities. Polystyrene is used in floating devices, such as buoys, as well as in fishing, boating and tourism. Polystyrene is also used in food containers and clothing. For these smaller microplastics, scientists have a hard time pointing out the source.

Additionally, smaller microplastics of the kind Medina Faull found in abundance, can contain a mix of particles, suggesting that the ocean contaminant likely came from a recycling process.

“We call them plastics, but there are [numerous] types of materials with different chemical compositions,” he said. These may interact differently with the environment and the oceanic organisms.

At this point, Medina Faull suggested that the majority of the ocean remains undersampled, which makes it difficult to know the concentration and distribution of microplastics.

Microplastics are also distributed in different parts of the ocean, as some of them float at the surface while others sink to the bottom. The process for vertical transport in the water column isn’t well studied.

New plastic producing technology

Some companies are working to develop bioplastic materials. Made from natural polymers or polymers produced by algae or bacteria, these plastics might dissolve more rapidly and provide a safer environmental alternative. These could be photo, bio or chemically degraded faster than synthetic polymers.

As for his own consumer decisions, Medina Faull thinks about ways to reduce his own plastic use regularly.

For starters, he tries to reduce the use of plastics in his own house. He drinks water from the tap and, when he does use plastic, he tries to make sure it’s more than for a single use. 

He urges residents concerned about the use of plastics to buy local products, which not only help the community but also reduce the need for as much plastics for shipping.

When he buys toys for his two-year-old daughter Aila Marina, he tries to make sure they’re manufactured with recycled plastic or wood.

Aerosolized plastics

When microplastics are small enough, they can become aerosolized amid a heavy surf, as the impact of water releases them into the air.

Areas in the Arctic and Antarctic have now found evidence of microplastics that were carried by the wind.

“We know that they are part of these complex transfer mechanisms in the ocean,” said Medina Faull.

A native of Margarita Island, Venezuela, Medina Faull spent considerable time growing up in and around water. He grew up going to the beach, surfing, scuba diving, and spearfishing.

Medina Faull and his wife Elizabeth Suter, who is also a marine scientist and works at Molloy University in Rockville Centre, live in Long Beach with their daughter.

When he’s not on, near or studying the water, Medina Faull appreciates the opportunity to create objects in his own woodworking shop. He has made furniture for his office, a toy chest for his daughter and picture frames.

As for the message from his work, Medina Faull believes any contamination is cause for concern.

“We need to be aware” of microplastics, he said. There are “so many things we don’t understand yet.”

For consumers, he urges people to be careful about what they are buying and consider ways to reduce plastics.

First responders who raced to the World Trade Center site on 9/11 or who helped with the massive clean up effort did so at risk to themselves.

That was as true during those days and weeks after the attack as it is now, with many of the first responders experiencing a range of diseases and conditions linked to the difficult work they did in 2001.

In a study released recently in the journal JAMA Network Open, Sean Clouston, Professor in the Program in Public Health and in the Department of Family, Population and Preventive Medicine in the Renaissance School of Medicine at Stony Brook University, showed that 4.6 percent of the responders in a study developed dementia. That compares with 0.5 percent for the general population of people who would develop cognitive declines in a similar age group.

Between November of 2014 and January of 2023, 228 responders without dementia and under 60 years old at the start of the study developed dementia over the next five years.

“It’s stunning to see these kinds of symptoms in such young people,” said Clouston.

Through the Stony Brook WTC Health and Wellness Program, Clouston and other researchers have documented some of the cognitive declines in this population, who likely inhaled the kinds of fine particulate matter that can enter the brain and cause damage even as the immune system fights to try to target the unwelcome contaminants.

“We assume this made it in the brain, but in such a way that it wasn’t overwhelming immediately,” said Clouston. “Once you get into a neurodegenerative space, most of these diseases take a long time to develop” with neurodegenerative processes sometimes taking decades to occur.

The exposure could have caused an immune reaction. They are not sure whether symptoms emerged because the reaction was stronger or if the symptoms developed because higher exposure triggered a stronger reaction.

“It’s like trying to fight a fire, and the truck rolls over a garden to do it,” said Clouston.

Fortunately, the brain has considerable redundancy, which makes it possible to reroute brain signals to compensate for problems. Over time, however, that ability might be damaged by that work or by the exposure.

Determining which particular chemical or chemicals causes the greatest damage is difficult, particularly because the collapse and burning of the buildings caused a heterogeneous mixture of so many industrial products to enter the air. It may not matter much, as any material in the brain could be a problem. The type of exposure may also affect the severity of the immune reaction or which parts of the brain are damaged.

Scientists suggest that some of the contaminants that have contributed to health defects may come from the various tools in offices, such as computers and air conditioners.

“As we go forward [with other studies], that will be a focus of ours, to see if we can’t isolate at least one or maybe a couple” of chemicals that could exacerbate the cognitive decline, Clouston said.

Different exposures

Clouston and his collaborators used surveys to find out exposure at the site.

Some of the first responders, for example, used face masks and wore personal protective equipment, including hazmat suits. The incidence of dementia among that group was considerably lower than it was for those who didn’t wear masks.

Five or six out of every 1,000 workers who wore PPE developed dementia, while those without protection developed cognitive decline at the much higher rate of 42 out of 1,000.

The researchers tried to address the possibility that those people who were masks lived a healthier lifestyle prior to 9/11 and may have already been less likely to develop diseases or health conditions.

“We tried to account for that,” Clouston said. In most cases, people aren’t avoiding the kinds of activities or decisions that likely contribute to dementia, such as diet and exercise, which, the general population “widely ignores already,” he said.

Additionally, while a family history of dementia or other medical conditions mattered to some degree for the reported cases, they weren’t sufficient to invalidate the statistically significant result.

To be sure, Clouston acknowledged that the study could have a screening bias, as cognitive evaluations every 18 months likely far exceeds how often most people in the same age group receive testing for their mental acuity.

This is one reason they developed a minimally exposed group that could account for that bias. In that group, dementia was close to, but still higher than the expected rates for the general population.

The number of first responders with dementia far exceeded this group.

Other health threats

Medical professionals have been studying the impacts of other events that release aerosolized particles that could be hazardous to people’s health and could damage the environment.

Burn pits, which the military used in Iraq and Afghanistan, among other locations, contributed to cancers and other diseases among members of the military serving overseas.

Natural disasters, such as the Maui fire last August that not only burned through forests but also destroyed commercial buildings, also create a hazard.

People fled the fire quickly and then returned to search for their loved ones, Clouston said, which exposed them to aerosolized dust.

It would be “good to think about studies to consider risk of dementia” from these events, he added. 

“These studies would probably take a while to complete as the risk grows with time and with age.”

Shhh, don’t tell anyone, but I just received a copy of the draft of the debate rules that were sent to the two older gentlemen who would like to be president from 2024 to 2028.

Now, no one was supposed to see these, but my friend’s nephew’s babysitter’s neighbor happened to be taking out his recycling and he noticed a piece of paper with official presidential letter head on it. I’m going to share a few ideas that almost made it into the debate.

First, the two candidates considered the possibility of a brief nap. Each of them would have had a pillow and a small bed, just off stage, where they could recover and restore their vim and vigor.

Second, they were considering whether to allow a translator for each of them. That way, when one of them misspeaks and uses the wrong name or mispronounces a word, a country, a language or a religion, the translator could auto correct for the moment.

Third, they each considered bringing a Pinocchio onstage. When the other person spoke, the nonspeaking candidate could demonstrate the perceived inaccuracy of the other person’s comments by extending the nose of their puppet. 

Fourth, they each considered at least 30 seconds when they could appeal directly and exclusively to their donors, explaining why they needed more money and how they would best use it.

Fifth, they were each given the opportunity to ignore one question openly and ask themselves a better one that they themselves could then answer.

Sixth, they wanted the chance to stump the other with their spectacular knowledge of the world. Each person could ask the other to spell the name of a particular country and then demonstrate their world prowess by pointing to that country on an unlabeled map.

Seventh, they could each choose a way to demonstrate their intellectual prowess by choosing from the following list: name as many digits of pi as possible, name the former presidents in order, share the names of some important Supreme Court decisions, or name as many national parks as they could.

Eighth, each candidate would have the opportunity, in a minute or less, to share a lesson they learned in the classroom that they believe has come in particularly handy in their lives.

Ninth, each candidate would have to name at least five people who aren’t relatives and who are alive who they think might be great presidents one day.

Tenth, before they offered their own positions, each president would have a chance to do their best impersonation of the other man. For 90 seconds, each of them could pretend to be the candidate for the rival party.

Eleventh, in the spirit of collaboration and cooperation, each one had to say something genuinely supportive and nice about the other person, and it couldn’t be about the person’s family.

Twelfth, each participant would need to spend at least 30 seconds sharing his thoughts on RFK Jr.’s candidacy.

Thirteenth, each candidate would have to indicate how he would be president for the entire United States and not just his constituency. Each candidate would be required to speak directly to the supporters of the other candidate, suggesting why people who have made up their minds should change their vote.

Fourteenth, both candidates would need to discuss something other than his rival as the greatest threat to the future of the United States.

Fifteenth, each candidate should discuss why, despite their frustration with the press that they think favors the other side, they still support the First Amendment. They would also need to share their views on the value of a free press, emphasizing in particular its ability to hold politicians accountable.

Sixteenth, the winner of the debate, as determined by an independent panel of disinterested observers, would circle the stage while sharing some dance moves of his choice.

Seventeenth, regardless of the outcome of the debate, the candidates agree to shake each other’s hands, to smile and to wish their competitor, their competitor’s family, and the country well.
