How does the temperature of a magnet affect its strength? Why does honey come in different colors? Are permanent markers really permanent? Curious students from schools across Suffolk County shared questions they explored using the scientific method at the 2023 Elementary School Science Fair hosted by the U.S. Department of Energy’s Brookhaven National Laboratory on June 10.

“Students from kindergarten to sixth grade who participate in the science fair use the fundamental skills that are the basis of the science conducted here at Brookhaven National Lab,” said Bernadette Uzzi, manager for K-12 programs in the Lab’s Office of Educational Programs (OEP). “Our goal is to develop today’s students into tomorrow’s scientists and engineers.”

After going virtual for three years, the competition returned to an in-person showcase at the Lab where students were ready to share their results and attend an awards ceremony for their grade level.

From delving into the physics behind speedy lacrosse tosses to studying how different materials react in salt water to crafting a codable maze, student’s experiments connected to the basics of wide-ranging research happening at Brookhaven’s world-class facilities. Many students opted to tackle clean energy solutions, including experiments that tested solar cars, asked whether food waste can produce energy, and showed how hydrogen can be produced through water electrolysis for a clean fuel option.

Cameron Casey, a first grader from Charles E. Walters Elementary School, hypothesized that light energy changes based on location. He used machines equipped with small solar panels and topped with clear plates that would spin if powered with enough energy from the sun. The only plate that spun was attached to a solar cell place directly in the sunlight.

Casey said his favorite part of participating in the science fair was that it led him to Brookhaven Lab, a place he’d been wanting to visit for a while. “I’m really proud of it,” he said. “It worked so well that it got me all the way to here.”

Other students incorporated their pets and demonstrated their passion for nature and the environment through their projects.

It was her love of the ocean and surfing that inspired Tatiana Panuthos, a fifth grader from South Bay Elementary School, to investigate microplastic pollution. “When I’m out there, I see all the plastic and garbage in the ocean, so one day, I came home and was researching the plastics I saw in the ocean,” she said. “But then I found the bigger problem and we can’t even see it: microplastics.”

After learning that much of the microplastic pollution in our oceans comes from fabric and clothing, Panuthos chose to build an inexpensive and easy-to-install filter to capture microplastics streaming out of laundry cycles.

Charlie Furman, a second grader at Fifth Avenue Elementary School asked: Can pinecones predict the weather? “My hypothesis was that I think pinecones can predict the weather because they contain a living thing,” he said. He collected pinecones and compared how they reacted to different temperatures and humidity. He found that in the cold, pinecones closed to protect their seeds, but opened as temperatures warmed up. It’s a test-the-weather project anyone can try out at home, he said.

Brookhaven Lab staff and local teachers volunteered as judges and event help.

“I love that the students are learning the scientific method,” said Kathy Haack, a science fair volunteer who teachers K-5 science at Westhampton Beach Elementary School. “They learn the difference between experiments and demonstrations, and the difference between an engineering project and an experiment.”

Allison McComiskey, chair of the Environmental & Climate Sciences Department at Brookhaven National Laboratory

By Daniel Dunaief

The wildfires last week in Quebec, Canada, that brought an orange haze, smoke and record pollution to New York were not only disconcerting, but also were something of a reality check.

These raging fires occurred earlier than normal and, with a so-called cut-off low in Maine acting like a bumper in a pinball game driving the smoke down along the eastern seaboard, created hazardous air quality conditions from New York through Virginia.

“There’s a real concern about this intensity, the size of the fire, happening this early in the season,” said Allison McComiskey, chair of the Environmental & Climate Sciences Department at Brookhaven National Laboratory. “Typically, wildfire season starts later in the summer and extends through the fall. If we’re going to be having wildfires of this size this early in the season and it continues, [there will be] much more of an impact on people in terms of air quality, health, and well being.”

Dry conditions caused by climate change intensified the severity of these fires, making them more difficult to extinguish and increasing the amount of particulates that can cause lung and other health problems thrown into the air.

“Wildfire season is getting longer,” said Dr. Mahdieh Danesh Yazdi, an air pollution expert and environmental epidemiologist from Stony Brook’s University’s program in Public Health. These fires are “spread because we have drier conditions, the vegetation is dry, we have droughts. Those require long-term solutions of trying to tackle climate change on a fundamental level.”

The intensity of the smoke and the cancelation of events like the Yankees and Phillies games has raised awareness of the downwind dangers from wildfires.

“This is like our Hurricane Sandy from an air quality perspective,” said Brian Colle, division head in Atmospheric Sciences at the School of Marine and Atmospheric Sciences at Stony Brook University. 

Scientists urged a multi-level approach to tackle a wildfire problem that they believe will become increasingly dangerous for human health.

Forest management, including controlled burns, would reduce the available fuel for fires started by natural causes such as lightning.

“Forest management may be one approach,” said Dr. Danesh Yazdi. That alone, however, won’t solve the threat from wildfires amid higher temperatures and more frequent droughts, she added.

McComiskey added that researchers are “certain” that wildfires are going to increase in the future due to climate change and suggested that these events ratchet up the need for getting better predictive models about what these fires will mean for human health and the climate.

The heavy smoke that descended on New York, which some health officials described as creating conditions for those who spent hours outdoors that are akin to smoking several cigarettes, is “a wake up call that we need policies” to deal with the conditions that create these fires, McComiskey said.

The increase by a “fraction of a degree in temperature is really not the point,” McComiskey added. “We need to decarbonize our economy and we need to move toward addressing the bigger causes of climate change.”

A wildfire occurring earlier in the year with smoke filled with particulates could raise awareness and attention to the dangers from such events.

“Having this kind of thing happen in the East Coast through New York and [Washington] DC, as opposed to where we typically think of bad wildfire happening out west, in Washington State and the Rocky Mountains, might help in terms of the awareness and urgency to take some action,” McComiskey added.

With a vision to turn parts of Governors Island into a world-class center that blends into the surrounding greenery, Stony Brook University won the highly competitive process to create a climate solutions center.

New York City Mayor Eric Adams (D) and the Trust for Governors Island earlier this week named Stony Brook the lead in teaming up with other universities, nonprofits and businesses to create a $700 million facility that will start construction in 2025 and open in 2028.

Backed by a $100 million donation from the Simons Foundation, a $50 million gift from Bloomberg Philanthropies and $150 million from the City of New York, Stony Brook will create a unique 400,000 square-foot facility.

The center will house research laboratories and host community discussions, train 6,000 people to work in green energy jobs per year, provide educational opportunities and search for climate solutions, including those that affect low-income communities of color.

“Climate change is here and the danger is real,” Adams said at a press conference on Governors Island unveiling the winner of the competition. “I am proud to announce that we have selected a team led by Stony Brook University to deliver the New York Climate Exchange.”

Adams suggested the Stony Brook team, which includes local partners like Pace University, New York University and the City University of New York, will protect the city’s air and water.

The Trust for Governors Island also anticipates the site, which will include a “semester abroad” on-site, fellowships and internship programs, will host scientific symposiums that can bring together leaders in a range of fields.

In an email, Simons Foundation President David Spergel hopes the center will “nucleate new business that generates jobs in the region, invest in new technologies and advance solutions.”

The foundation is helping to recruit other benefactors to meet the financial needs for the site both by the example of its commitment and through personal interactions, Spergel said.

Stony Brook, meanwhile, which has a deep pool of researchers at the School of Marine and Atmospheric Sciences investigating climate-related issues, doesn’t plan to wait until the buildings are refurbished and constructed to start the conceptual and educational work.

During phase zero, the university will “work with our partners immediately” on developing programs for kindergarten through grade 12 outreach, on scaling up green workforce development and on developing collaborative research projects across institutions, SBU President Maurie McInnis said in a town hall discussion with the campus community.

Practice what it preaches

In addition to providing space that will generate and test out ideas for solutions to climate change, the New York Climate Exchange buildings will minimize the carbon footprint.

There will be 230,000 square feet of new space and 170,000 square feet of refurbished existing structures. The plans, which were created by Skidmore, Owings & Merrill, involve creating the biggest mass-timber building in New York City. As an alternative to concrete and steel, mass timber has a lower carbon footprint and is lighter.

Mass timber uses “less material and in a more efficient way,” said Keith O’Connor, principal at SOM, who runs the city design practice in New York and Washington, D.C., in an interview.

SOM designed the tops of the buildings with 142,000 square feet of solar cells, which will generate more than enough power for the site, enabling the center to provide all of its electricity needs and to send some energy to the city.

“We wanted to work really hard to avoid having a field of solar panels sitting off to the side” or sticking solar panels on each roof, O’Connor said. Instead, the solar panels, which will be at slightly different angles from each other, track the topography of the structures without creating a glaring field of reflected light.

Guests who arrive at Governors Island will notice a solar canopy that is “front and center,” O’Connor said. “It’s about a message for everyone who is visiting — it says that energy generation is critical.”

SOM wanted to find a way to create a warm and welcoming aesthetic that provides energy, O’Connor added.

All of the nondrinking water will come from rainwater and treated wastewater.

The site anticipates diverting 95% of waste from landfills, making it one of the first in the country to achieve true zero-waste certification.

“The concept of the physical structure is astonishing,” David Manning, director of Stakeholder Relations at Brookhaven National Laboratory, which will serve as an adviser on the center, said in an interview. “You want to attract the best and the brightest. You do that with programming. It doesn’t hurt that [the design and the facilities] are also cool.”

An aerial rendering of the island after construction, which will also include 4.5 acres of new open space, looks more like a park than a typical research station.

Governors Island, which hosts about a million visitors each year who arrive on ferries that run every half hour, plans to double the ferry service, with trips traveling every 15 minutes during the day starting next year. Also in 2024, the city will start using a hybrid electric ferry to reduce emissions.

Considerable collaborative support

McInnis expressed her gratitude to the team at Stony Brook and to her partners for putting together the winning proposal.

McInnis suggested that the university’s commitment to studying, understanding and mitigating climate change, coupled with national and international collaborations, would unite numerous strengths in one place.

“We knew we had the right team to lead this effort,” said McInnis at the announcement on Governors Island. “We also knew we needed a diverse set of partners” in areas including environmental justice, in the business sector and in philanthropic communities.

Other partners include Georgia Tech, University of Washington, Duke University, Rochester Institute of Technology and University of Oxford, England.

BNL’s Manning appreciated the opportunity to attend the kickoff of the project on Governors Island. 

Near the tip of Manhattan amid a “stunning blue sky,” the gathering was the “perfect setting” to announce and create solutions that were “this future focused,” Manning said.

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

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

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

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

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

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

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

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

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

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

Awards Ceremony for Bridge Contest 2023
High school students become model bridge engineers in annual contest

Jacqueline Seifert, a senior at Commack High School, won first place in the 2023 Bridge Building Competition hosted by the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory on March 30.

The annual contest puts model bridges constructed by Long Island High School students to the ultimate pressure test. Students apply physics and engineering principles to build basswood structures to a set of specifications. Then, their bridges are judged based on efficiency, which is calculated using the mass of the bridge and the amount of weight it can support before breaking or bending more than one inch.

“This competition is an introduction to the world of engineering,” said Scott Bronson, manager for K–12 programs at the Lab’s Office of Educational Programs (OEP). “At Brookhaven Lab, engineers of all types support our science goals at world-class facilities and the DOE mission. We hope this contest inspires students to explore paths in science, technology, math, and engineering and to return to the Lab as interns and future employees.”

OEP received a total 142 bridges, of which 91 qualified for testing, captured below.

An awards ceremony to honor the winners was held at Brookhaven Lab on April 6. The top two winners in this regional competition qualify to compete in the International Bridge contest on April 29 in Chicago, IL.

Seifert, who earned second place in last year’s local competition and placed 16th in the previous international contest, designed a bridge that weighed 23.47grams and recorded an efficiency of 1342.22. As the testing machine slowly added more and more weight to Seifert’s W truss design, the Science Learning Center erupted in impressed “oohs” as the load hit close to 70 lbs. Retired Brookhaven Lab engineer and longtime competition supporter Marty Woodle noted right away “that’s an international contender.”

Seifert, who will pursue civil engineering at Vanderbilt University, said it was rewarding to watch her design hit that high bridge load. “The most exciting part was the experimentation and seeing what works and what doesn’t, finding the weak points in my bridge so I could continue to make it better,” she said. “I’ll see how it goes in the international competition.”

Katherine Liang, a junior at Ward Melville High School, who garnered first place in two previous contests and 9th and the last international competition, placed second this year with a design that realized an efficiency of 1094.44.

Third-place winner Jonathan Thomas, a junior at Walt Whitman High School, constructed a bridge that recorded an efficiency of 1048.18. After conducting bridge demos in a physics lab at school, Thomas learned his design needed more horizontal support and looked to previous competition winners for potential engineering ideas.“It’s definitely a career path I want to go into,” he said.

Aidan Quinn, a junior at Smithtown High School East won this year’s aesthetic award. Quinn’s double arch design was neat with clean lines, inspired by a photo his father showed him that captured a historical moment when a pilot flew a biplane under a bridge that once crossed the Niagara River.

“I would love to major in biomedical engineering,” Quinn said. “I’m glad I was able to participate in the competition. It was a great experience.”

JoAnne Hewett has been named the new BNL director. Photo from SLAC National Accelerator Laboratory

For the first time in its over 75-year history, Brookhaven National Laboratory named its first female lab director.

JoAnne Hewett, associate lab director for fundamental physics and chief research officer at SLAC National Accelerator Laboratory in Menlo Park, California, will take over the top job at BNL this summer.

Hewett will also join Stony Brook University as a tenured faculty member in the Department of Physics and Astronomy and the C.N. Yang Institute for Theoretical Physics.

Hewett “is not only incredibly qualified and talented, but will also make history as the first woman to serve in this critical role,” Gov. Kathy Hochul (D), who is the first woman elected governor of the Empire State, said in a statement. “The lab has developed innovative ways to deliver on New York’s top priorities, from battling disease to acting on climate change, that are making a difference today and for the future of New York.”

Hewett, who was the first woman member at SLAC in 1994, conducts research as a theoretical physicist, exploring the fundamental nature of space, matter and energy. Her work in physics focuses on efforts beyond the Standard Model of particle physics.

Stony Brook University Distinguished Professor and Director of the C.N. Yang Institute for Theoretical Physics George Sterman described her hire as a “wonderful turn of events.”

In an email, Sterman wrote that her work “as a theoretical physicist has earned wide admiration, and her leadership has helped shape the national program in fundamental particles.”

Sterman suggested Hewett’s research “continues to influence experiments worldwide, and her perspectives will be greatly valued by her new colleagues at Stony Brook.”

With over 2,800 scientists, engineers, technicians and professionals and an annual budget of about $700 million, the researchers at BNL tap into the site’s state-of-the-art technology, including the National Synchrotron Lightsource II. These researchers, and the many scientists from around the country and the world, work in fields including nuclear and high energy physics, clean energy and climate science, quantum computing, artificial intelligence, photon sciences, isotope production, accelerator science and technology and national security.

Hewett is coming to BNL as it prepares to begin construction on the Electron-Ion Collider, or EIC. Estimated to cost between $1.7 billion and $2.8 billion, the EIC will allow researchers to look inside the nucleus at the protons and neutrons. The research will reveal the arrangement of quarks and gluons that make up the protons and neutrons of nuclei.

Discoveries from the EIC could lead to future technologies.

“I am head-over-heels excited to build the EIC in partnership with Jefferson Lab to unlock the mysteries of the force that binds Nature’s building blocks, to strengthen connections to industry and the community with Discovery Park, and to advance the multi-program missions of the lab,” Hewett said in a statement. “And I’m very much looking forward to working with everyone at Brookhaven, Stony Brook and the DOE to usher the lab into its next successful chapter.”

The lab is also building a new welcome center, the Science and User Support Group, which is the first building planned for Discovery Park.

Maurie McInnis, president of SBU and co-chair of the BSA Board of Directors, which is a partnership between SBU and Battelle, welcomed Hewett, who will start this summer, to BNL.

Hewett’s “capable leadership, experience and future-forward vision complements Brookhaven National Laboratory’s continued focus on scientific innovation and discovery,” McInnis said in a statement. “The University is pleased to bring her expertise to the Physics and Astronomy Department and to the C.N. Yang Institute of Theoretical Physics, both of which have had “long-standing and critical connections to many major physics achievements at BNL.”

The next few months

Hewett takes over the top job at the lab from Doon Gibbs, who had been in that position from 2013. Gibbs is retiring on April 17.

“I am grateful to [Gibbs] for his outstanding leadership of Brookhaven and his long legacy of building and strengthening the lab for advancing scientific discovery,” Hewett said in a statement.

Jack Anderson, BNL’s deputy director for operations, will serve as the interim lab director until Hewett joins the lab.

Tom Daniels, the current ALD for Facilities and Operations will serve as interim deputy director.

Finally!

Brookhaven National Laboratory has had nine lab directors since it was founded in 1946. Earlier this week, the Department of Energy facility, which has produced seven Nobel Prizes, has state-of-the-art facilities, and employs over 2,800 scientists and technicians from around the world announced that it hired JoAnne Hewett as its first female lab director.

Successful, determined, dedicated and award-winning local female scientists lauded the hire of Hewett, who comes to BNL from SLAC National Accelerator Laboratory where she was associate lab director for fundamental physics and chief research officer. SLAC is operated by Stanford University in Menlo Park, California. In email responses, local female scientists suggested that Hewett’s hiring can and would inspire women in science, technology, engineering and math (STEM) fields.

“I am so delighted by the news that Dr. JoAnne Hewett has been named to be the next director of Brookhaven National Laboratory,” wrote Esther Takeuchi, William and Jane Knapp chair in Energy and the Environment and SUNY distinguished professor at Stony Brook University and chair of the Interdisciplinary Science Department at BNL. As the first female director for the lab, Hewett “is an inspiration not only for the women who are in the field, but for future female scientists who will witness first hand that success at the highest level.”

Stella Tsirka, SUNY distinguished professor in the Department of Pharmacological Sciences at the Renaissance School of Medicine at Stony Brook University, suggested this hire was a part of an increasing number of women in prominent positions in science at local institutions.

Stony Brook and BNL are “becoming a hub of strong female role models for younger females, in STEM, in medicine, in leadership!” Tsirka wrote. “Between [SB President] Maurie McInnis, Hewett, Ivet Bahar (the director of the Laufer Center), Anissa Abi-Dargham [principal investigator for the Long Island Network for Clinical and Translational Science] and many other successful female faculty in leadership positions, hopefully, the message comes out loud and clear to our young women who are in science already, or aspire to be in science.”

For her part, Abi-Dargham, who is chair in the Department of Psychiatry and Behavioral Health, described Hewett’s hire as “amazing” and suggested it was “really exciting to see an accomplished female scientist selected to head our collaborating institution at BNL!”

Cold Spring Harbor Laboratory Professor and Cancer Center Program co-leader Mikala Egeblad added that the significance of Hewett’s hire goes “well beyond inspiring young girls. It is important to have women leaders for all sciences, also for someone at my career stage. I hope that one day, we will get to a point when we don’t think about whether a leader is a woman or a man.”

Women remain underrepresented at top leadership positions, so Egeblad finds it “very inspiring to see a woman recognized for her leadership skills and selected” to head BNL.

Leemor Joshua-Tor, professor and HHMI investigator at CSHL, called the hire “really great news” and indicated this was “especially true for the physical sciences, where there are even fewer women in senior positions than in biology.” Joshua-Tor added that the more women in senior, visible positions, “the more young women and girls see this as a normal career to have.”

Alea Mills, professor and Cancer Center member at CSHL, wrote that it is “fantastic that BNL has found the very best scientist to lead them into their next new mission of success. And it’s an extra bonus that this top scientist happens to be a woman!”

Mills added that efforts to enhance diversity are fashionable currently, but all too often fall short. Hiring Hewett makes “real traction that will undoubtedly inspire future generations of young women in STEM.”

Patricia Wright, distinguished service professor at Stony Brook in the Department of Anthropology, wrote that it was “inspiring” to see a female director of BNL and that “young female scientists can aspire to being in that role some day.”

By Daniel Dunaief

Combining forces to form a three-part team, they strive to understand processes that are as visually stunning and inspirational as they are complex and elusive.

Clouds, which are so important to weather and climate, are challenging to understand and predict, as numerous processes affect properties at a range of scales.

A team from Brookhaven National Laboratory has provided the atmospheric sciences community with a host of information that advances an understanding of clouds.

In the atmospheric sciences community, “we typically talk about the three legs of a stool: modeling/ theory; field measurements; and targeted laboratory studies,” explained Arthur Sedlacek, Chemist in the Environmental and Climate Science Department.

Sedlacek conducts field experiments by collecting air samples from clouds in a range of locations such as flying through wildfire plumes.

In the beginning of 2021, BNL added postdoctoral researcher Ogochukwu Enekwizu to bolster another leg of that stool. Enekwizu conducts the kind of laboratory studies that provide important feedback and data for the work of Sedlacek and cloud modelers like Nicole Riemer, Professor in the Department of Atmospheric Sciences at the University of Illinois-Urbana Champaign.

Enekwizu studies how soot aerosols from wildfires influence the lifetime and formation of clouds. She’s also investigating how soot-cloud interactions affect the absorption and scattering of light by soot particles.

Wildfires provide kindling for the climate, as fires release warming agents that contribute to increases in global temperatures which result in more wildfires. By determining how these smaller scale processes in soot affect clouds, Enekwizu can reduce the so-called error bars or level of uncertainty in the models other scientists create and that rely on the data she develops.

Enekwizu’s collaborators appreciate her contribution. As a modeler, Riemer suggested that Enekwizu’s work provided key information.

“While the microscale processes of soot restructure are incredibly complicated, [Enekwizu] was able to boil it down to a few simple parameters,” Riemer explained. “This makes it feasible to implement this process in a model like ours, which look at aerosol populations, not just a few individual particles. From there, we can come up with ways to implement this knowledge into climate models, which are still much more simplified than the model that we are developing.”

Sedlacek, who is her supervisor, suggested that Enekwizu’s work is “now on the cusp of answering important questions of how aerosols interact with clouds.” He descried her set up as “truly unique” and expects her results to inform the community about wildfire aerosol-cloud interactions and will offer guidance on other necessary field measurements.

In broader research terms, wildfires can be important for the ecosystem, as they remove decaying material, clear out underbrush, release nutrients back into the soil and aid the germination of seedlings

The increasing frequency, duration and intensity of these fires has been important to the scientific community. The general public has become increasingly aware of its importance as well, Enekwizu said.

Collaborations

Recruited to BNL by Sedlacek and Atmospheric Scientist Ernie Lewis, Enekwizu is considering collaborations with other researchers at BNL.

She has started speaking with scientists at the Center for Functional Nanomaterials about exploring soot microstructure in a planned joint collaboration with her New Jersey Institute of Technology PhD advisor Dr. Alexie Khakizov. For this effort, Enekwizu has been in discussions with Dmitri Zakharov, who is in charge of the environmental transmission electron microscope at the CFN.

She hopes to take samples and introduces forces under a controlled environment in the transmission electron microscope to see how that affects the structure of soot in fine detail.

Looking at the news with one wildfire event after another, Enekwizu feels compelled to conduct research in the lab and share data amid “a heightened sense of urgency to get this work done” and to share it with the world at large.

Scientific origins

Born in the southeastern part of Nigeria in Enugu and raised in Enugu, Lagos and Abuja, Enekwizu developed an interest in science at 13. She enjoyed classes in a range of sciences and said chemistry was her favorite.

“I knew I was not going to go into medicine because I was squeamish,” she said.

Chemical engineering fascinated her and also appeared to offer career opportunities.

During a chemical engineering internship, she worked at the Nigerian National Petroleum Corporation where she learned about flaring practices. It inspired her final year project on biogas as a renewable energy source and sparked her curiosity on the fate of pollutants and particulate matter that arise from legal and illegal flaring activities. 

In flaring, companies burn off excess gas to control pressure variations, increasing the safety of the operation at the expense of burning a potential resource.

When Enekwizu was at NJIT, Lewis, who is a longtime collaborator with Sedlacek, reached out to Khakizov to inquire about someone with a background in carbonaceous aerosols. After interviewing with Lewis, Sedlacek and others, Enekwizu received the job offer and began working in January of 2021.

A resident of Ridge, Enekwizu, who goes by the name “Ogo,” enjoys festivals and events around Long Island. She also appreciates the area’s ubiquitous beaches and has delighted in strawberry picking.

She hopes to explore Montauk later this spring or summer.

Mentoring

Enekwizu is passionate about mentoring students, particularly those who might be under represented in the field of Science, Technology, Engineering and Medicine.

She served as a graduate student mentor for Divyjot Singh, who was an undergrad at NJIT. Enekwizu taught Singh, who had grown up in Bhopal, India and had only been in the United States for six months when they met, “how to come up with research questions, how to develop hypotheses, how to write a proposal, how to make good presentations for conferences and everything in between,” he explained in an email.

While working with her, Singh found his passion for research and decided to pursue a PhD. 

Enekwizu is also passionate about supporting young women in science. She suggested that young black girls sometimes feel intimidated by STEM classes and careers. She urges a hands on approach to teaching and hopes to be a role model.

“If young girls see people like me thrive in STEM, they’ll be encouraged not to give up,” she said. “That is a huge win, in my opinion.”

Alistair Rogers lives, thinks and works on opposite extremes.

At the same time that he gathers information from the frigid Arctic, he is also analyzing data from the sweltering tropical forests of Panama and Brazil. He visits both regions annually and, within one eight-day span, saw a Polar Bear in Utqiaġvik (formerly known as Barrow), Alaska and a tarantula in Brazil.

That’s not where the extremes end. Rogers is also studying plants at the physiological level to understand how best to represent processes such as photosynthesis, respiration and stomatal conductance in climate models.

The leader of the Terrestrial Ecosystem Science & Technology Group in the Environmental and Climate Sciences Department at Brookhaven National Laboratory, Rogers recently was honored as a Fellow of the American Association for the Advancement of Science.

The AAAS has named fellows every year since 1874 to recognize their contributions to the advancement of science. Previous honorees included astronaut and former Johnson Space Center Director Ellen Ochoa, a founding member of the NAACP and scholar W.E.B. Du Bois and inventor Thomas Edison.

Lisa Ainsworth, Research Leaders of the Global Change in Photosynthesis Unit for the USDA Research Service, nominated Rogers, who served as a mentor for her when she conducted her PhD research.

“[Rogers] is one of the world’s authorities on understanding how plants respond to atmospheric change and in particular rising carbon dioxide concentration,” Ainsworth said. He’s an experimentalist who “built a bridge to the scientific computational modeling community.”

Ainsworth suggested she would not have the career she developed if it weren’t for the support she received from Rogers.

Rogers, who the Department of Energy recognized as an Outstanding Mentor three times and has been at BNL since 1998, “makes you believe in yourself when you don’t have any reason to do that. He believes in you before you know you should believe in yourself,” Ainsworth said. For his part, Rogers is “delighted to be honored and recognized as a fellow.”

Carbon dioxide sinks

For all the extremes in his work, Rogers has been collecting data from plants to address a range of questions, including how they will react to and affect environmental changes caused by global warming.

Through photosynthesis, plants are responsible for absorbing about a third of the carbon dioxide humans produce through the burning of fossil fuels.

The uptake of carbon dioxide by plants and oceans has limited warming so far to 1.2 degrees Celsius above pre-Industrial temperatures. Without such carbon dioxide removal by oceans and plants, the temperature would already be 3 degrees warmer.

The models his work informs are trying to understand what will happen to the carbon dioxide subsidy in the future.

“In order to work out how warm it’s going to get, you need to know the carbon dioxide concentration and the climate sensitivity (how much warmer it will get for a given amount of carbon dioxide),” he explained in an email.

Photosynthesis is less efficient at higher temperatures, but is also more efficient amid an increased amount of carbon dioxide. Drier air also reduces the efficiency of the process as plants close their stomata to conserve water, which restricts carbon dioxide supply to their chloroplasts.

The transfer of water from land to the atmosphere most often occurs through stomata, so understanding the way these pores open and close is important in predicting cloud formation and other land-atmosphere interactions.

Ainsworth described how a typical day of field work gathering data could last for 16 hours. She appreciated how Rogers worked and played hard — he is a cyclist and a skier — while keeping the work fun. Indeed, Ainsworth said Rogers, on regular calls with two other professors, blends discussions about grants and work decisions with their first choice for their guesses at the New York Times wordle game.

Leadership roles

In addition to his leadership role at BNL, Rogers is also part of the leadership teams for the Next Generation Ecosystem Experiment — Arctic and the Next Generation Ecosystem Experiment —Tropics.

Rogers said the Arctic is seeing the biggest increase in temperature relative to anywhere else on the planet faster because of climate feedback. When ice and snow melt, it reveals surfaces that absorb more heat.

The tropics, meanwhile, have been more stable, although the region is expected to experience hotter, drier temperatures in the coming decades as well.

The Department of Energy is studying these biomes because they are climatically sensitive, globally important and poorly represented in climate models.

Rogers is working with other scientists at BNL and around the world to understand these processes to feed his data collection and analysis into global models.

Using an analogy for developing these models, Rogers suggested trying to predict the time it would take to get to the airport. A traveler would need to know the distance and the mode of transport — whether she was walking, biking or riding in a car.

A model predicting the travel time would make assumptions about how fast a person could go in a car, while factoring in other data like the weather and traffic density at a particular time to anticipate the speed.

If the traffic model wasn’t sure of the maximum possible speed of a vehicle, the error associated with predicting the arrival time could be large, particularly when considering the difference between traveling in a steamroller or a Lamborghini on empty roads.

Climate models use a similar process. By studying the species of plants, Rogers can tell the models whether the plants are the equivalent of sports cars or steamrollers.

Big picture

The worst case scenario of earlier models is highly unlikely, although the scenario of a drastic reduction in carbon dioxide also hasn’t occurred. The models, however, still suggest that changes in human behavior are critical to protecting the future of the planet against the effects of climate change.

Rogers is encouraged by the declining cost of solar energy and the work developing countries have done to bypass some of the more polluting sources of energy from the industrial revolution. He is also pleased by the commitment from the Department of Energy to look for climate change solutions.

These elements “represent great opportunities for scientists like me” to work on these problems.

Hunter College Campus Schools and Ward Melville High School took the top spots in the Long Island Regional Science Bowl competitions hosted by the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory on Feb. 2 and Feb. 3. The fast-paced question-and-answer contest quizzed students on chemistry, biology, physics, mathematics, astronomy, and general, earth, and computer science.

Science Bowl alumni Suraj Muralidharan, Stephanie Zhang, and Amanda Chen volunteered at the 2023 competitions.

This year, the regional middle and high school events returned to an in-person, head-to-head tournament at the Laboratory after going virtual for two years due to the COVID-19 pandemic. About 80 volunteers including BNL staff, community members, and past Science Bowl participants helped out this year.

“Brookhaven’s Office of Educational Programs was so excited to welcome students back onsite for a full day of competition and science learning,” said Amanda Horn, a Brookhaven Lab educator who coordinated the events. “This competition provides students with a unique opportunity to show off their science skills and knowledge, and learn about the Lab as well as the DOE.”

Hunter College and Ward Melville’s first place wins in the middle school and high school competitions, respectively, secured each team an all-expenses paid trip to compete at DOE’s National Science Bowl finals scheduled for April 27 to May 1 in Washington, D.C.

The DOE created the National Science Bowl in 1991 to encourage students to excel in mathematics and science and to pursue careers in these fields. Approximately 330,000 students have participated in the National Science Bowl® throughout its 32-year history, and it is one of the nation’s largest science competitions.

“The National Science Bowl® is an extraordinary competition that brings together young minds across America through science and technology,” said Asmeret Asefaw Berhe, DOE Office of Science Director, “and I would like to congratulate the Hunter College Campus Middle School and Ward Melville High School teams as they advance to the National Finals! Good luck to you — our future scientists, visionaries, and leaders!”

Middle School Science Bowl Results

First Place: The regional middle school event held on Feb. 2 was open to teams from New York City schools in addition to schools on Long Island. Under the guidance of coaches Jennifer Kasanuki and Christopher Torpey, a team from Hunter College Campus Schools of NYC — Kieran Torpey, Gabriel Fang, Max Levin, Andres Fischer and Camille Pimentel — earned a back-to-back win for their school after being tied halfway through the final round against R.C. Murphy Junior High School of Stony Brook.

“It feels really great,” said Hunter College team captain and eighth grader Kieran Torpey. “We’ve studied really hard for this. I love science and to know a lot of science is really great.”

Second Place: R.C. Murphy Junior High School — Harry Gao, Gabrielle Wong, Menghan Tang, Willem Van der Velden, Kayla Harte (Coaches: Jillian Visser and Emily Chernakoff)

Third Place: John F. Kennedy Middle School Team 1 — Chaeten Modgil, Maya Swierupski, Jayden Brun, Aiden Karp, Ryan Perovich (Coach: Steven Nielsen)

Fourth Place: NYC Lab Middle School for Collaborative Studies Team 1 — Ryan Casey, Jonathan Lin, Vince Liao, Kolbi Canell, Daniel Berkovich (Coaches: Faithe Theresa Yates and Eva Deffenbaugh)

High School Science Bowl Results

First Place: Competing against 23 other teams, Ward Melville High School of East Setauket secured their first-place win in a second-round showdown against Great Neck South High School on Feb. 3. 

Under the guidance of Coach Philip Medina, team members — Benjamin Proothi, Rithik Sogal, Anna Xing, Benjamin Zhang and Michael Melikyan — went undefeated in their first four round robin matches and reached the double-elimination finals where they faced a team from Great Neck. 

Great Neck gave them their first lost, but Ward Melville High School pulled through during the tiebreaker round where they surged ahead with a rally of several questions and bonus points — an intense, yet exciting way to win.

“We didn’t really know exactly what the score was,” said Ben Proothi. “We just felt like we were ahead by a little bit, so we took the chance and ran out the clock.”

“It’s incredible,” said team captain and junior Michael Melikyan. “We’ve always been fighting Great Neck South for a top spot, and they’ve always been taking it. They always have a strong team and incredible people and we’re just happy we finally managed to pull through. We’re very grateful and very proud to be going [to the National Science Bowl].” 

This marks the first time in six years Ward Melville High School has qualified for the national tournament. “They’re an amazing group of people. I have no idea how they know this stuff, it’s incredible. They were working so well under pressure. I’m very proud of them,” added Coach Medina.

Second Place: Great Neck South High School — Richard Zhuang, Laura Zhang, Brandon Kim, Eric Pei, Erin Wong (Coaches: James Truglio and Nicole Spinelli)

Third Place: Farmingdale Senior High School — Waseem Ahmad, Ali Ahmad, Madhav Rapelli, Bevis Jiang, Rayan Adamjee, (Coach: Ashley Arroyo)

Fourth Place: Jericho Senior High School — Derek Minn, Natasha Kulviwat, He Xuan, Ashwin Narayanan, Brendan Shek (Coaches: Samantha Sforza and Emily Umile)

—————————————–

Brookhaven Lab’s Office of Educational Programs (OEP) organized science fun for students throughout both competition days with a STEM Expo, tour, and additional science challenge. Staff and visiting students offered hands-on science demonstrations that included a cloud chamber that revealed electron tracks, sound and light sensitive microcontrollers, tricky engineering attempts, and robotic building blocks.

Science Bowl teams that did not move on to the competitions’ final double elimination rounds had the chance to get an up-close look at the STAR detector at the Relativistic Heavy Ion Collider (RHIC), a DOE Office of Science User Facility for nuclear physics research. STAR, which weighs 1,200 tons and is as large as a house, tracks thousands of particles produced by ion collisions at RHIC to uncover clues about the universe in the moments after the Big Bang.

Teams also competed in a STEM Challenge, racing against the clock and each other to solve science and math puzzles to break several locks on boxes filled with treats. Among participating middle schools, Elmont Memorial High School earned first place, Sayville Middle School took second, and Great Neck South Team 1 placed third.

Long Beach High School completed the STEM Challenge first among participating high schools, followed by General Douglas Macarthur Senior High School, then Lynbrook Senior High School. Long Beach student Sam Adler used the periodic table to crack the code for one of the team’s final locks.

“It was so much fun,” Adler said. “I was so stressed during the competition itself and this was all good fun.”
