Come September, middle and high school students across the North Shore will wake up to the harsh sound of alarms, sometimes hours before the sun will rise.

Some will wake up late, and rush in and out of the shower, sometimes not having time to eat before they make it to the bus stop, often in the dark where the cicadas continue to buzz and the crickets chirp.

Port Jefferson high schoolers will shuffle through the front doors before 7:20 a.m. Students at Ward Melville High School will hear the first bell at 7:05, while Comsewogue students will be in their seats at 7:10.

Some scientists across the North Shore have said that needs to change.

The science

Brendan Duffy has worked in St. Charles Hospital’s Sleep Disorders Center for nearly a decade, coming out of working at Stony Brook University as a sleep technician. As he worked in the field, he started seeing significant connections between the effectiveness of individuals during the day and how much sleep they got the night before. For teens, he said, the importance is all the greater. Sleep, he said, has a direct impact on risk-taking versus making smart choices, potential drug use, obesity and depression.

“The science is irrefutable,” he said. “Basically, anything you do, whether it’s mentally or physically — it doesn’t directly cause [these harmful decisions], but there’s connections and links.”

While some parents would simply tell their kids to get off their phone or computer and go to bed, scientists have said the bodies of young people, specifically teenagers, have internal clocks that are essentially set two hours back. Even if a young person tries to fall asleep at 9 p.m., he or she will struggle to slumber. Duffy said scientists call it the delayed sleep phase, and it directly affects the timing of the body’s melatonin production.

During sleep, the body enters what’s called “recovery processes,” which will regulate certain hormones in the brain and effectively flush all waste products from daily brain activity. Without enough sleep, these processes do not have time to work.

“The science is irrefutable.”

That is not to mention rapid eye movement sleep. REM sleep is a period during the night where heart rate and breathing quickens, and dreams become more intense. Lauren Hale, a sleep researcher and professor of preventive medicine at Stony Brook University, called this period critical to sleep. The longest period of REM happens in the latest part of the sleep cycle, the one deprived by waking up early. 

“For decades, scientists have known young people are sleep deprived,” she said. “It’s not that they can get by on six or seven hours of sleep … teenagers are the most at risk of not getting the sleep they need.”

Of course, it is not to say modern technology has not affected young people. Duffy said phones and computers have meant the brain is never given time to rest. Even in downtime, minds are constantly active, whether it’s playing video games or simply scrolling through Facebook.

“They’re not given a break,” Duffy said. “Their brains are constantly processing, processing, processing.”

Sleep and sports

“I looked at all the school athletic programs that have been decimated by changing their start times, and I couldn’t find anything,” Duffy added. “It’s hard for athletes to perform or recover if they’re not sleeping well at the high school level.”

In research, college football teams looked at which kids were likely to be injured, and those who received less than eight hours of sleep were 70 percent more likely to be injured, according to Duffy.

That research led him to find Start School Later, a nonprofit national advocacy group to change the minimum school start time to 8:30 a.m., at a minimum. Duffy communicated with the nonprofit to provide data on the effect lack of sleep has on players. He has become its athletic liaison.

He points to professional sports teams, many of which have sleep professionals whose jobs are to set sleep schedules for their players and help reach peak effectiveness.

History of sleep and schools

Dr. Max Van Gilder is a retired pediatrician and coordinator for the New York branch of Start School Later. He said that while most schools traditionally started at 9 a.m. for most of the 20th century, the move toward earlier start times was relatively recent, only beginning around 1975 with busing consolidation. Schools started doing multiple bus runs for different grade levels, and high school students would be the first ones on these routes.

For decades, the early start became more and more established. Start School Later was created little more than a decade ago, but it’s only recently that some states have started to try later times.

In 2016, Seattle passed a law moving start times from 7:50 to 8:45 a.m. A study of the effects of that change showed students got an average of 34 more minutes of sleep a day or several hours over the course of the week. It also showed an improvement in grades and a reduction in tardiness. The study gave examples that in some classes average grades were up 4.5 points more than previous classes at the earlier start times.

“We need to work with the superintendents.”

— Max Von Gilder

In California, a bill that would have moved minimum start times to 8:30 a.m. was supported by both houses of the state Legislature before being vetoed by the governor last year. A similar bill is currently going through the legislative process again. Other states like Virginia and New Jersey have started to experiment with later start times.

On Long Island, very few districts have made significant increases in start times. Van Gilder said two-thirds of the high schools in New York state (excluding NYC) start before 8 a.m., with an average start time around 7:45. Only 2 percent of high schools start after the recommended time of 8:30, according to him.

The main difficulty of encouraging later start times is due to districts being so largely independent from both the state and each other. While this gives each district particular freedoms, it also means cooperation is that much harder. A district that changes start times would have to renegotiate with bus companies and find ways to navigate scheduling sports games between schools with different start times.

“The state constitution makes it very difficult for the State of New York to pass a law to say when you can start,” Van Gilder said. “We need to work with the superintendents.”

However, proponents of late start said the benefits easily outweigh the negatives.

“There are ways around it and, to me, this is a strong evidence base for opportunity to improve adolescent medical health, physical health, academic outcomes, safer driving — there is such a positive range of outcomes,” said Hale of SBU.

Parents working together

In the Three Village Central School District, more than two dozen parents filled a meeting room in Emma S. Clark Memorial Library Aug. 23. Barbara Rosati, whose daughter is an eighth-grader in P.J. Gelinas Junior High School, organized the meeting to discuss the benefits of teenagers starting school later in the day.

Rosati, a research assistant professor at SBU’s Renaissance School of Medicine in the Department of Physiology and Biophysics, said during conversations with Van Gilder she discovered there are only four high schools in New York that begin school as early or earlier than Ward Melville’s 7:05 start time. Because of their internal clocks, she described the teenagers as constantly being jet lagged.

“Older kids — adolescents, high schoolers, junior high school students — for them it’s much more difficult to get up early in the morning, and this has a physiological
basis,” Rosati said.

The goal of the Aug. 23 meeting was to go over studies, create an action plan and then put that plan into motion. The professor pointed toward the studies that show teenagers who are sleep deprived can be more susceptible to mood swings and drowsiness, and it can affect academic and athletic performance as well as cause long-term health problems such as anxiety, diabetes, eating disorders and cardiovascular problems.

“We’re spending a lot of money in this district to make our schools better and improve their performance, and then we undermine the kids with things like sleep deprivation,” Rosati said. “We undermine not only their health but academic performance.”

“We’re doing this because we care about our children’s mental health and academic achievement.”

— Barbara Rosati

Parents at the meeting agreed they need to be sympathetic to the school board, and Rosati added that she believed, based on prior experience, that the board would be willing to help.

“We have to show them our support, and at the same time we have to make sure they are willing to do this and feel committed to such an effort, because this is not something that you do halfheartedly,” she said.

Frances Hanlon, who has a sixth-grade student in Setauket Elementary School, agreed that the parents can work with the board trustees and that it wasn’t an us-versus-them issue.

“We can’t be, ‘We know better than you and why aren’t you?’” Hanlon said. “We all have to work on this together and that’s what’s going to make a change.”

Rosati and those in attendance are set to survey how many families are in the district and, when the school year begins, will start a petition for those in favor of late start times to sign.

Among the suggestions parents had were bringing the late school start presentation that Rosati created to the school board and PTA meetings throughout the district, with further plans to record and send it by email to parents. One mother also suggested that high school students join the parents at BOE meetings. Rosati said she would also like to have experts such as Van Gilder and Hale present a talk for the board trustees.

“We can use the help of these professionals to inform the board that there is really solid scientific evidence, and we’re not just doing this because we’re lazy and don’t want to get up early in the morning,” Rosati said. “We’re doing this because we care about our children’s mental health and academic achievement.”

Reaction from districts

Both of Duffy’s kids are already graduates of the Port Jefferson School District, and he has yet to present in front of the school board, saying he wants to gain more traction in the community before bringing it to school officials. He has been trying to get support through posts on social media.

“It really can’t come just from me, it has to come from the community,” he said.

Though Hale has gone in front of school boards at Shoreham-Wading River and a committee in Smithtown, she lives in Northport and has two young girls at elementary school level. She has also written editorials in scientific journals about the topic.

When Rosati attended a Three Village board of education meeting in June, she said a few trustees told her that starting high school later in the day could lead to eliminating some of the music programs while teams may not be able to compete against neighboring schools in sporting games.

After her appearance before the school board, she said she researched a number of schools on Long Island, including Jericho High School which starts at 9 a.m. and saw that they could still manage to have music programs and play schools at sports with different start times.

A statement from the Three Village School District said it had commissioned a lengthy discussion regarding school start times, but while it was in support of the research, it identified negative impacts to the athletic programs, transportation, BOCES offerings and elementary music.

“You don’t have to look hard to see the benefits of this.”

— Lauren Hale

 

The district said it also conducted an informal survey of a small portion of the student population, who said they were not in favor of later starts, but Three Village added it was only used to gather anecdotal information.

There are a few things parents can do to aid their child’s sleep beyond the later start. Rosati offered some tips, including regular bedtimes, providing balanced meals, curfew on screen times, and limiting extracurricular activities and the intake of sugar and caffeine in the evening hours. She and her husband have tried their best to follow those guidelines, but she said they still kept their daughter home multiple days due to sleep deprivation last academic year.

“We should not be put in the position to choose between education and health for our kids,” Rosati said.

When asked, Shoreham-Wading River, Port Jefferson and Northport school districts all said they were not currently looking into later
start times.

Still, Hale said despite her frustrations with the reaction from some districts she’s continuing to argue for later start times.

“We need to work together with communities so that parents and teachers and school board members understand this is for the benefit of the students and the community,” she said. “You don’t have to look hard to see the benefits of this.”

Rosati plans to host another meeting Sept. 10 at the Emma S. Clark Memorial Library in Setauket from 7:30 to 9 p.m.

Tiny nematodes like this one were found to be unexpectedly hardy, reviving after thousands of years frozen in Arctic ice. Stock photo

Back in 1968 I gave a futuristic public lecture at UCLA in which I predicted that the mummified tissue of long dead people could be used to reconstruct their genotypes and, if the chemical tools became available, this could lead to what I called “necrogenetic twinning.”

That got on the wire services and I got clippings with headlines like “King Tut may become a papa.” I also got letters from the public including one irate lady who said, “If you were my son, I’d beat you with a broomstick.” Well there is a field of paleogenetics today, and it is being used to work out the genomes of Neanderthal ancestors and may some day be used to bring back old favorites like passenger pigeons and dodos.

But there is a more immediate source of bringing back a few of the presumed long dead that are present in permafrost. The term was coined in 1943 in a report carried out by the U.S. Army. It is an acronym for permanently frozen soil. That is not ice in waterlogged soil. When permafrost is subject to warm temperatures, it thaws. It does not melt. But from that thawed material the organic matter can be isolated and dated by carbon-14 techniques to get the age. 

Recently, Russian scientists studying thawed permafrost discovered samples (one 32,000 years old and the other 42,000 years old) that produced live nematodes that had been frozen for a very long sleep. They began moving a few weeks after removal and eating bacteria and protozoa on a petri dish. These are roundworms related to vinegar eels as they are called, which can be seen in organic vinegars served in restaurants. Hold such a cruet of vinegar to the light and you will see what look like tiny flakes jittering about in the vinegar.

It is not just cold temperature that can preserve life for centuries. Date palm seeds that are more than a thousand years old have been planted and produced fruit bearing dates. The record of the deepest sleep, however, goes to bacterial spores isolated from salt crystals in rock that was present 250 million years ago. They hatched from their protected state and formed bacterial colonies.

I would not be surprised to find future core samples from ocean cores taken in rock that may be as old as the first life-forms on Earth (viruslike) whose sequences might reveal the first genotypes capable of sustaining life in the organic soup thought to be present when the lifeless Earth was formed. That is a speculation that appeals to the imagination. But we humans can also imagine other possibilities that are less charming than alarming.

What if these early life-forms, whether from permafrost or ocean dredgings, contain pathogens that find humans a suitable host? Ancient viruses would not be treatable by antibiotics, and vaccines might be needed to check their spread. Ancient bacteria might be contained by present-day antibiotics, but some might not.

But is that not true of humans who have explored Earth? Many have come down with diseases they did not know existed in the ruins of ancient civilizations. When Darwin was in the Amazon, he contracted Chagas disease, which made him sickly in his later life. My father was in the Merchant Marine in his youth and came down with malaria and had summer chills when the sporozoans decided to celebrate.

That is why my wife Nedra and I had to get several vaccinations when we traveled on Semester at Sea. When we approached equatorial countries, we had to take anti-malarial medication to prevent coming down with a life-threatening malaria infection. Life is full of risks and not all are predictable, but using knowledge often thwarts unknown threats we may encounter.

Many who attended the 3rd annual Eastern Long Island Mini Maker’s Faire in Port Jefferson were first greeted to was a bear — hulking, rusted statue of a bear with arms of wood and corroded steel, a torso of used tires and organs made from oil filters and oil sumps. In the center of his chest was a cow heart suspended in formaldehyde.

“Bear” the sculpture by local team Dirt People Studios, was just one of many demonstrations of science, art and ingenuity at the fair, hosted by the nonprofit Long Island Explorium.

Scientists demonstrated the dangers of storm surges on Long Island, while robotics teams from Stony Brook University and other local high schools showed off what they have worked on for the past year.

Local DiYers like Jim Mason of LB Robotics, a maker of strange and interesting robotics, showed his work with a 3D printer and his projects using parts and tools he has found around his home.

“The music, the sun, the fun and play, see ya next year, Robo say,” Mason posted to his Facebook page.

Centuries of scientific experimentation and exploration will be preserved in Shoreham.

Concluding months of nail-biting anticipation, the Wardenclyffe property in Shoreham, made famous as the last standing laboratory of famous 19th- and 20th-century scientist and inventor Nikola Tesla, finally made it onto the U.S. National Register of Historic Places July 27.

The designation is the culmination of hard work by the nonprofit Tesla Science Center at Wardenclyffe to get the site listed on local, state and national lists of historic places.

Marc Alessi, the science center’s executive director, said the site landing on these historic registers helps to guarantee that the property will survive through future generations.

“Listing on the National Historic Register not only helps preserve Nikola Tesla’s last remaining laboratory, but it allows us to move forward with renovations and plans to develop Wardenclyffe into a world class science and innovation center,” Alessi said. “[The] listing also opens doors for funding, as many grants require official historic status.”

Members of Tesla Science Center spent close to a year gathering data on the historic nature of the site located along Route 25A in Shoreham. They hired a historic architecture consultant to document which parts of the 16-acre property were historical and which were not.

The property was considered for historical site status by the New York State Historic Preservation Office June 7 after receiving 9,500 letters of support from people all over the world. The property passed that decision with a unanimous vote of approval, and it was then sent to the National Park Service for a decision to place the property on the national register.

“We hope that this will remind people of the importance of Tesla and his work at Wardenclyffe,” Tesla center President Jane Alcorn said.

The Shoreham property was home of one of Tesla’s last and most ambitious projects of his career. His plan was to build a tower that could, in theory, project electricity through the ground as a way of offering free energy to everyone in the area. Creditors seized upon his property after it was learned there would be limited ways of monetizing the project.

Tesla spent his remaining years for the most part in solitude and obscurity until his death in 1943. Recent decades have shown a resurgence of interest in Tesla for his groundbreaking technologies such as the Tesla Coil, a 19th-century invention used to produce high-voltage alternating-current electricity, and Alternating Current which is used in most electronics today.

In 2012 the science center worked with The Oatmeal comic website to launch a successful Indiegogo campaign that raised $1.37 million to purchase the land. Since then the nonprofit has renovated the property with plans to turn the site into a museum and incubator for technology-based business startups.

The air buzzed with electricity in Shoreham Saturday as community members and Tesla aficionados attended the second annual Tesla Birthday Expo: Neon 2018 at Tesla Science Center at Wardenclyffe in Shoreham.

The July 14 event was held on the famous 19th- and 20th-century scientist and inventor Nikola Tesla’s 162nd birthday. Both adults and kids stood in wonder as they interacted and played with some of Tesla’s most notorious inventions, like the Tesla coil, a 19th-century invention used to produce high-voltage alternating-current electricity. Participants also got to interact with electric Tesla vehicles, robots from local robotics teams and learn the history of the location itself.

The Wardenclyffe site was home to one of Tesla’s last experiments, a tower that would have transferred free electricity wirelessly through the earth itself.

“Tesla had enormous dreams,” Tesla center President Jane Alcorn said. “We’re standing here where Tesla’s ambitious project to impact the world with the wireless transmission of messages was embodied by the tower that once
stood here.”

The center bought the property in 2002 after a successful online crowdfunding campaign. The nonprofit group is now looking to turn the site into a museum, science exhibition center and incubator for science-based projects. The science center hopes to have the first part of a functioning museum up and running by the end of next year, as currently the buildings on the site are not open to the public.

This post was updated July 17 to correct the name of the event to the Tesla Birthday Expo: Neon 2018.

Im not a scientist and I don’t play one on TV. Nonetheless, I think science is undervalued in America. I believe the typical American takes science for granted, thinks science owes them something and figures they’ll never understand what scientists are saying.

Wrong, wrong and wrong.

For starters, science isn’t just about trying to create the best iPhone, the highest quality and thinnest televisions, or medicines that act like magic bullets, destroying evil in our cells or our DNA without damaging the healthy ones.

Science often starts with a question. Why or how does something work? And, perhaps, if we change something about the way it works, does it get better or worse? The conclusions scientists draw when they solve one puzzle leads to the next set of questions.

It’s as if a child asks his parent if he can go west and the parent says, “No, don’t go west, but here are the keys to the car.”

The answer may seem like a non sequitur, but it’s also a way to navigate somewhere new, even if, for whatever reason, the car isn’t supposed to go west. Maybe, by learning more about the car and where it can go, the child also learns what’s so forbidding about going west, too.

We want science to succeed and we’re annoyed when science doesn’t solve our problems. We can’t get something to work or we can’t get ourselves to work and we blame scientists. After all, if we can send a man to the moon, why can’t we conquer the morning rush hour or the common cold?

Then again, how does the study of dark matter — neutrinos or sphingolipids — affect our morning commute? We may not understand these areas, but that doesn’t mean basic knowledge can’t or won’t lead to advances we can’t anticipate.

Knowledge, as we know, is power. If we know, for example, that an enemy is planning an attack and we know where and how that attack will occur, we can defend ourselves, even if that enemy exists at a subcellular level.

Learning the playbook of the enemy takes time, which technological innovation, dedicated researchers and people battling against a disease often don’t have.

Worst of all, though, science is somehow too hard to understand. That is a defeatist conclusion. Yes, scientists use technical terms as shorthand and, yes, they may not be selling ideas or themselves in the kind of carefully crafted tones often reserved for CEOs or politicians.

That, however, doesn’t mean they are planting a keep-out sign in front of them or their ideas. While scientists reduce a question to an attainable goal, they also often keep a larger goal in mind.

A few years ago, my daughter had to draw a picture of what she thought a scientist looked like. Rather than imagine a person in a white lab coat with one pocket full of pens and the other holding a radiation badge, she drew a baby.

Science may be frustrating because scientists often come across as uncertain. For example, they might say, “We believe that the shadow in our telescope may be caused by an exoplanet orbiting a star that’s outside the solar system, and which is the same distance from its nearest star as Earth is from the sun.”

Scientists can be wrong, just as anyone can be wrong in their job, in their opinions or in their conclusions. That, however, doesn’t make science wrong. Scientists are often most excited when a discovery they make defies their expectations or bucks conventional wisdom.

Just because conventional scientific wisdom changes doesn’t mean every part of it is wrong.

Science doesn’t have all the answers and it never will. The most likely person to tell you that, though, should be a scientist, not a journalist.

More than 100 years after his great-grandfather designed and oversaw the construction of Nikola Tesla’s Wardenclyffe laboratory in Shoreham, Sebastian White, a renowned physicist and St. James native, filled a local lecture hall to discuss all things surrounding the Serbian-American inventor.

White, whose famous ancestor Stanford White’s architectural achievements include Washington Square Arch, the original Madison Square Garden and what is now the Tesla Science Center, took time out of his busy schedule as a particle physicist for CERN — the European Organization for Nuclear Research — to engage a roomful of science lovers Aug. 27.

The presentation was in conjunction with the center’s summer-long Tesla exhibit in Stony Brook and ended with a screening of clips from “Tower to the People,” a documentary made by a local filmmaker about the laboratory.

The physicist, and chairman of the Tesla Science Center’s Science Advisory Board, examined the litany of Tesla influences in modern-day technology and the late-19th century culture that helped shape his genius.

“Today it’s very clear that Tesla is trending in much of the science that’s showing up, such as wireless transmission of energy, which is a new field, and the Tesla car, but I think we shouldn’t only remember him for what he did, but also the incredible time in America he became part of,” White told the 130 residents packed into the lecture hall on the top floor at The Ward Melville Heritage Organization’s Educational & Cultural Center. “I think the story of Tesla, who many of my colleagues don’t even know, is an important one as it tells us how we got to where we are.”

White explained how Tesla’s grand vision for wireless transmission of energy, which eventually culminated in a torn-down tower on the Shoreham site in 1917, remains a much-pursued concept.

“There’s a very lively industry happening today, mostly because people keep forgetting to charge their iPhones and they want to find a way to do it without needing cords,” he said.

Through a process called energy harvesting, industry scientists are actively working on ways to charge cellphones while they sit inside pockets by capturing energy just from the environment.

“It’s an enormous field now — new companies are very interested in it and a lot is happening,” White said, pointing out other examples of wireless power transmissions over the years. “In 1964, on the Walter Cronkite TV show, a guy named William C. Brown demonstrated a model of an electric helicopter powered by a microwave. The United States, Canada and Japan have experimented with airplanes powered by radio waves. I would say, probably, if Tesla were around today, he’d be more happy about all the things people are inventing with new techniques rather than always quoting him and saying, ‘Well, Tesla said this.’”

White said Tesla’s emergence as one of the most influential scientific minds of all time coincided with what he referred to as “an incredibly important time” in the late 1800s, a period referred to as the American Renaissance.

Among the prolific figures with whom Tesla interacted were writer Mark Twain, physicist Ernest Rutherford, American businessman John Jacob Astor IV, and, of course, Stanford White. The physicist said a huge year for Tesla was 1892, when he lectured and demonstrated his experiments at the Institution for Electrical Engineers at the Royal Institution in London.

Speaking on his great-grandfather and Tesla’s friendship, which proved itself through many projects prior to Wardenclyffe, White referred to one particular exchange.

“Stanford White [once] invited Tesla to join him for an outing with William Astor Chanler, an explorer,” he recounted. “Tesla said, ‘I’m busy in the lab.’ White kept pushing him and then wrote to him, ‘I’m so delighted that you decided to tear yourself away from your laboratory. I would sooner have you on board than the Emperor of Germany or the Queen of England.’”

David Madigan, a Tesla Science Center board member, said after the lecture that having White’s perspective on this near-and-dear subject was integral.

“It’s important having Dr. White give the talk, who’s a physicist himself and whose grandfather was Stanford White, who was intimately involved in Tesla’s advancement of his many ideas both as an investor and also as an architect,” Madigan said. “It’s a good triangulation of today’s event, the Tesla exhibit, and Dr. White bringing in the scientific and family history.”

White said he has always felt a strong connection with his great-grandfather, who had a home in Smithtown, since he was  young.

“He was part of our life for sure,” he said. “We all felt very close to him. My son is an architect, my aunt and uncle were architects, my grandfather was an architect, and even continued in the same firm.”

East Setauket resident Michael Lubinsky said he was drawn to the lecture through a lifelong interest in Tesla.

“I always felt that Tesla was not appreciated that much in his time,” Lubinsky said, laughing that much of the lecture went over his head with its scientific terms.

Paul Scala, a software engineer living in Centereach, said he too gravitated to the event to explore more of Tesla’s story.

“I think [Dr. White] did a very nice job,” he said. “It’s very cool seeing that in the tech world they’re still trying to harness wireless energy.”

Shoreham’s Tesla Science Center at Wardenclyffe is hosting the Electric Dream Expo Saturday, July 8 — a community event honoring science innovator Nikola Tesla’s 161st birthday, as well as the 100th anniversary of the dismantling of Tesla’s famous wireless transmitting tower. The Electric Dream Expo is comprised of an afternoon Science & Innovation Expo from 2 to 6 p.m. on the site of Tesla’s last existing laboratory in Shoreham, with exhibits, demonstrations, food and entertainment.

There will also be an evening of Tesla entertainment, called Summer Electrified!, from 8 to 10 p.m. at Shoreham-Wading River High School, 250A Route 25A, Shoreham, featuring Tesla-inspired performances.

Technological innovation of the past, present and future is the expo’s theme, and attendees at the daytime Science & Innovation Expo will experience Tesla-themed exhibits and activities for all ages, including a HAM radio presentation, displays by The Museum of Interesting Things and Long Island Radio & TV Historical Society, Tesla coil exhibit, 3-D printer and robotics demos, interactive exhibits of Tesla inventions and a Tesla car display.

Tours and a special presentation of innovation will feature the history of Tesla’s 187-foot wireless transmitter tower, built on the Shoreham site in 1907 and dismantled 100 years ago. The tower’s base remains as a focal point, along with Tesla’s Wardenclyffe Laboratory, built from 1901 to 1905 by renowned architect Stanford White, and now being renovated into an immersive science and education center.

The Summer Electrified! an evening of Tesla entertainment, features ArcAttack!, a musical light show using Tesla coil technology, as well as a unique lineup of performances and readings focused on Tesla’s life and legacies.

Admission to the Science & Innovation Expo is $15 for ages 13 and over, $5 for ages 5 to 12 and free for children under 5. Tickets for the Summer Electrified! performances are $25 per person 13 and over, $12 for ages 5 to 12 and free for children under 5. Admission to both events is $35 for 13 and over, $15 for ages 5 to 12 and free for children under 5. A special price of $25 per car covers admission to the daytime Science Innovation Expo for all passengers, and is limited to the first 50 car tickets purchased. Tickets can be purchased at www.teslasciencecenter.org.

On a sun-splashed Saturday afternoon, members of the community young and old had the chance to get outside and exercise their imagination at the third Eastern Long Island Mini Maker Faire. The popular event, hosted by the Port Jefferson Maritime Explorium June 10, saw demonstrations using robots, interactive activities, exhibits and performances from various “makers” at the Village Center and outside at Harborfront Park.

The Port Jeff maker faire is a scaled down version of the larger Maker Faire brand, which hosts worldwide events similar to the one in Port Jeff. According to the Maritime Explorium’s website, more than 100 makers and 2,000 participants attended the 2016 Mini Maker Faire, and even more were projected to show up this year, although final totals were not readily available.

Some of the makers on display included Funtown Studios, which brought an interactive fireball sculpture; robotics teams from the Sachem and Smithtown school districts; electricity and magnetism demonstrations by representatives from the Tesla Science Center at Wardenclyffe in Shoreham; an underwater robotic demonstration by SeaPerch; representatives from Stony Brook iCREATE, an innovation facility designed to encourage “innovation and entrepreneurial nature” of the Stony Brook University campus community; and many more.

Before the 2016 faire, Stephanie Buffa, a volunteer board member at the Explorium, explained the importance of the message of the event and the museum as a whole.

“Everything is at our fingertips,” she said in a phone interview. “If you’re sitting at the dinner table and somebody asks a question, you ‘Google’ it. It’s so easy to get answers that way…it’s so easy to get caught up in all of these pre-packaged things that we forget to sort of, do it yourself. You can be creative in so many ways. You don’t have to be a good artist and be able to draw beautiful pictures to be creative and to make things.”

Lauren Hubbard, founding president and former executive director of The Maritime Explorium, who is listed as a producer of the faire, said the day was a success, though attendance numbers are not available as of yet. She said in a phone interview the goal of the event is to show local people of all ages they have the creativity to be makers.

“It’s really about highlighting the entrepreneurial spirit,” she said. “It’s a great opportunity for young people to see how that process happens, how to create something completely new.”

I have had the privilege of teaching high school science (biology, chemistry and physics) for the last thirty years. For the last ten years, I’ve had the additional privilege and responsibility of developing and teaching an elective we simply call “Food Science.” It’s not your usual health class dietary guidelines, nor does it rehash the familiar mantras of counting calories and exercising to balance intake. Instead, we study the cultural, historical, scientific, political and economic contexts of our food system and how that system impacts our environments, both external and internal. This in turn enables students to make much more informed decisions about what they want to put in their bodies.

When it comes to sugars, confusion is the name of the game. There are dozens of ingredients that mark the presence of sugars in our food: maltodextrin, dextrose, invert sugar, cane sugar, high fructose corn syrup and starch, to name a few. Regardless of what the food industry calls them, your body sees basically three end products of their digestion: glucose, fructose and galactose. Which ones you eat, and how much, will dictate both their value and their danger to you.

You may have heard of three additional sugars — lactose, sucrose and maltose. Lactose is a combination of one glucose and one galactose. Also known as “milk sugar,” lactose is the nemesis of lactose-intolerant individuals who lack sufficient quantities of the enzyme that can digest it. Instead, bacteria that reside in their intestines get to process it, making painful amounts of gas as a by-product. Galactose can be converted to glucose in your body, but most individuals do not consume enough dairy to make this a source of concern.

Maltose is another type of sugar. It is a pairing of two glucose units and is the namesake for maltodextrin, etc. Consuming foods with maltose adds glucose to your diet — worth keeping track of as part of your total glucose consumption.

However, the most likely source of sugars in your diet is either sucrose or high fructose corn syrup. Sucrose, known also as table sugar, can be derived from sugar cane (cane sugar) or sugar beets (sugar.) Like lactose and maltose, sucrose is a paired structure, made of one glucose subunit and one fructose subunit. That is what your body absorbs regardless of the source (even organic.)

Sparing you the science behind its production, high fructose corn syrup is approximately half glucose, and half fructose too. Regardless of the marketing efforts by the Sugar Association and the Corn Refiners Association to make you believe one is better for you than the other, they end up, metabolically, in a virtual tie. Debating which to consume is a distraction from the consequences of consuming too much of either, or both.

The consumption of sugar (the term is legally owned by the Sugar Association as the sole name for sucrose) used to be limited by the relative expense and difficulty in obtaining it from its tropical source. Now the record levels of corn production in America have made it relatively cheap to produce and distribute sugar’s nearly identical-tasting competitor, high fructose corn syrup. You can find it in soda for sure, but also in pickles, peanut butter, ketchup and pretty much anywhere sugar might be used for additional appeal to consumers.

This has paved the way for the combined consumption of these sweeteners to reach more than 150 pounds per year per person in America. This far surpasses the 60 pounds per year considered by some experts to be the maximum amount that can be metabolized without ill consequences including diabetes, cardiovascular disease, fatty liver, cataracts, personality and cognitive dysfunction, some cancers and (by the way) obesity.

Tying glucose and fructose consumption to the metabolic consequences noted above requires further discussion. And now, you are properly prepared for those lessons. As we say in Food Science class, “Chow!”
