After setting the American record for the longest consecutive streak of 340 days away from Earth aboard the International Space Station, astronaut Scott Kelly returned and flopped into a pool.

While we all haven’t been away from Earth for any length of time, we have been living in a modified version of the normal we knew.

Like Kelly, we have spoken with our close friends and family through electronic devices that beam them onto a screen in front of us.

We have watched some of their drained faces, as they isolated themselves for a month or more, battling through the cough, fever and discomfort of COVID-19.

We have also seen our relatives at much greater than arm’s length as we celebrated landmark birthdays, the birth of new family members, and socially-distanced graduations and limited-attendance weddings.

In two weeks, I am anticipating the familiar feeling of diving into a familial swimming pool. That’s when I will see family members I haven’t seen in over a year.

We worked around our busy schedules not only to get vaccinated before we saw each other in real life, but also to do so long enough in advance of that meeting that our immune systems would have time to arm themselves against viral spike proteins.

This is the longest period my wife and I have ever been separated from our parents. We know how fortunate we are that our parents didn’t get sick.

We took nothing for granted, staying away from our parents and extended family. We might as well have been on the International Space Station, which was probably among the safest places people have ever lived, given the limited social contact in a controlled environment 254 miles from the nearest pool, family member or pizza restaurant.

We feel so much closer to a more familiar life than we have in over a year, as we anticipate seeing our parents and family members who can attend our son’s graduation. The planned visit has become a dominant and daily topic of conversation in our house. We are wondering what food and drink to serve, how to move everyone from nearby hotels to socially-distanced seating at graduation and what games to prepare in our backyard for our grown children to play with their cousins.

These questions and decisions might have seemed like a responsibility prior to the pandemic, as hosting anyone requires attention to detail and consideration for our guests. That responsibility has transformed into the kind of privilege we might have taken for granted in other years, before the pandemic disrupted family gatherings and turned the calendar into a reminder of delayed gratification of family gatherings.

While we will likely engage in the Texas two-step, trying to gauge how close we can get physically to each other, it’s easy to imagine that hugs, kisses and appreciative smiles will bubble up from the excitement of a backyard that has hosted more routine gatherings of birds, squirrels and chipmunks than of the people who stare at flickering screens in our home.

As we prepare to dive into our own family pools of support, affection and love, we are incredibly grateful to everyone who made such a return to normal possible, from those who explored the basic science that led to the vaccine, to those who developed and tested the vaccine, to those who treated family and friends, to those who stocked the shelves with the food and drinks we needed to take us from the uncertainty of the pandemic to the anticipation of a celebration. Absence made our hearts grow fonder for family and increased our appreciation for everyone who allowed us to reunite with the most important pieces of ourselves. In just a few weeks, we look forward to diving into a more familiar world.

Different people respond to the same level of stress in a variety of ways. For some, a rainy Tuesday that cancels a picnic can be a minor inconvenience that interrupts a plan, while others might find such a disruption almost completely intolerable, developing a feeling of helplessness.

Scientists and clinicians have been working from a variety of perspectives to determine the cause of these different responses to stress.

Cold Spring Harbor Laboratory Professor Linda Van Aelst and a post doctoral researcher in her lab, Minghui Wang, recently published a collaborative work that also included graduate student Nicholas Gallo, postdoctoral researcher Yilin Tai and Professor Bo Li in the journal Neuron that focused on the gene Oligophrenin-1, which is also implicated in intellectual disability.

As with most X-linked diseases, the OPHN1 mutation primarily affects boys, who have a single X chromosome and a Y chromosome. Girls have two X chromosomes, giving them a backup gene to overcome the effect of an X-linked mutation.

In addition to cognitive difficulties, people with a mutation in this gene also develop behavioral challenges, including difficulty responding to stress.

In a mouse model, Wang and Van Aelst showed that the effect of mutations in this gene mirrored the stress response for humans. Additionally, they showed that rescuing the phenotype enabled the mouse to respond more effectively to stress.

“For me and [Wang], it’s very exciting,” Van Aelst said. “We came up with this mouse model” and with ways to counteract the effect of this mutated analogous gene.

As with many other neurological and biological systems, Oligophrenin1 is involved in a balancing act in the brain, creating the right mix of excitation and inhibition.

When oligophrenin1 was removed from the prelimbic region of the medical prefrontal cortex, a specific brain area that influences behavioral responses and emotion, mice expressed depression-like helpless behaviors in response to stress. They then uncovered two brain cell types critical for such behavior: the inhibitory neurons and excitatory pyramidal neurons. The excitatory neurons integrate many signals to determine the activity levels in the medial prefrontal cortex.

The inhibitory neurons, meanwhile, dampen the excitatory signal so they don’t fire too much. Deleting oligophrenin1 leads to a decrease in these inhibitory neurons, which Van Aelst found resulted from elevated activity of a protein called Rho kinase.

“The inhibitor keeps the excitatory neurons in check,” Van Aelst said. “If you have a silencing of the inhibitory neurons, you’re going to have too much excitatory response. We know that contributes to this maladaptive behavior.”

Indeed, Wang and Van Aelst can put their metaphorical finger on the scale, restoring the balance between excitation and inhibition with three different techniques.

The scientists used an inhibitor specific for a RhoA kinase, which mimicked the effect of the missing Oligophrenin1. They also used a drug that had the same effect as oligophrenin1, reducing excess pyramidal neuron activity. A third drug activated interneurons that inhibited pyramidal neurons, which also restored the missing inhibitory signal. All three agents reversed the helpless phenotype completely.

Japanese doctors have used the Rho-kinase inhibitor fasudil to treat cerebral vasospasm. which Van Aelst said does not appear to produce major adverse side effects. It could be a “promising drug for the stress-related behavioral problems” of oligophrenin1 patients, Van Aelst explained in an email. “It has not been described for people with intellectual disabilities and who also suffer from high levels of stress.”

Van Aelst said she has been studying this gene for several years. Initially, she found that it is a regulator of rho proteins and has linked it to a form of intellectual disability. People with a mutation in this gene had a deficit in cognitive function that affected learning and memory.

From other studies, scientists learned that people who had this mutation also had behavioral problems, such as struggling with stressful situations.

People with intellectual difficulties have a range of stressors that include issues related to controlling their environment, such as making decisions about the clothing they wear or the food they eat.

“People underestimate how many [others] with intellectual disabilities suffer with behavioral problems in response to stress,” Van Aelst said. “They are way more exposed to stress than the general population.”

Van Aelst said she and Wang focused on this gene in connection with a stress response.

Van Aelst wanted to study the underlying cellular and molecular mechanism that might link the loss of function of oligophrenin1 with the behavioral response to stress.

At this point, Van Aelst hasn’t yet studied how the mutation in this gene might affect stress hormones, like cortisol, which typically increase when people or mice are experiencing discomfort related to stress. She plans to explore that linkage in future studies.

Van Aelst also plans to look at some other genes that have shown mutations in people who battle depression or other stress-related conditions. She hopes to explore a genetic link in the brain’s circuitry to see if they can “extend the findings.” She would also like to connect with clinicians who are studying depression among the population with intellectual disabilities. Prevalence studies estimate that 10 to 50 percent of individuals with intellectual disability have some level of behavioral problems and/or mood disorders.

Reflecting the reality of the modern world, in which people with various conditions or diseases can sequence the genes of their relatives, Van Aelst said some families have contacted her because their children have mutations in oligophrenin1.

“It’s always a bit tricky,” she said. “I don’t want to advise them yet” without any clinical studies.

A resident of Huntington, Van Aelst arrived at CSHL in the summer of 1993 as a post doctoral researcher in the lab of Michael Wigler. She met Wigler when he was giving a talk in Spain.

After her post doctoral research ended, she had planned to return to her native Belgium, but James Watson, who was then the president of the lab, convinced her to stay.

Outside of work, Van Aelst enjoys hiking, swimming and running. Van Aelst speaks Flemish, which is the same as Dutch, French, English and a “bit of German.” 

She is hopeful that this work may eventually lead to ways to provide a clinical benefit to those people with intellectual disabilities who might be suffering from stress disorders.

And the winner is … Eszter Boros. An Assistant Professor in the Department of Chemistry at Stony Brook University, Boros recently won the 2021 Stony Brook Discovery Prize, which includes $200,000 in new funding.

The prize, which was established in 2013, is designed to fund higher-risk research for scientists who are no more than five years beyond tenure and promotion at the Associate Professor level or who are on a tenure track as an Assistant Professor. The research might not otherwise receive financial support from agencies like the National Institutes of Health.

Stony Brook awards the prize to a faculty member who is considered a rising star.

Boros’s proposal suggests using a radioactive light switch to activate anticancer molecules.

The goal behind Boros’s work is to target cancer cells in particular, while avoiding the kinds of painful side effects that typically accompany chemotherapy, which can lead to gastrointestinal discomfort and hair loss, among others.

Boros, who has been at Stony Brook since 2017, was pleased to win the award. “It’s really exciting,” she said. “I’m kind of in disbelief. I thought all the finalists had convincing and exciting projects.”

The four finalists, who included Eric Brouzes in biomedical engineering, Gregory Henkes in geosciences and Kevin Reed in climate modeling, went through three rounds of screening, culminating in a Zoom-based 10-minute presentation in front of four judges.

Bruce Beutler, the Director of the Center for the Genetics of Host Defense at the University of Texas Southwestern Medical Center, served as one of the four judges.

In an email, Beutler wrote that Boros’s work had an “inventive approach” and was “high risk, but potentially high impact.”

Beutler, who won the 2011 Nobel Prize in Physiology and Medicine, suggested that the Discovery Prize may give a start to “a bright person with relatively little track record and a risky but well reasoned proposal.”

The success from such a distinction “does build on itself,” Beutler wrote. “Other scientists hear of such awards or read about them when evaluating future proposals. This may influence decisions about funding, or other awards, in the future.”

Boros said she would use the prize money to fund work from graduate students and post doctoral fellows, who will tackle the complexities of the work she proposed. She will also purchase supplies, including radioactive isotopes. She hopes to stretch the funds for two and a half or three years, depending on the progress she and the members of her lab make with the work.

The idea behind her research is to send radioactive materials that emit a light as they decay and that bind to the cancer cell. The light makes the chemotherapy toxic. Without that light, the chemotherapy would move around the body without damaging non-cancerous cells, reducing the drug’s side effects.

She is thinking of two ways to couple the radioactive light-emitting signal with an activated form of treatment. In the first, the two parts would not be selectively bound together.

The chemotherapy would diffuse into tissues around the body and would only become activated at the target site. This may affect healthy neighbors, but it wouldn’t cause as many side effects as conventional chemotherapy. This could take advantage of already clinically used agents that she can combine.

In the second strategy, she is taking what she described as a “next level” approach, in which she’d make the radioactive agent and the chemotherapy react with one another selectively. Once they saw one another, they would become chemically linked, searching to find and destroy cancer cells. This approach would require new chemistry which her lab would have to develop. 

Beutler suggested that Boros’s work might have other applications, even if cancer might currently be the best one. Some focal but infectious diseases can be treated with antimicrobial therapy which, like cancer directed chemotherapy, is toxic, he explained.

The same principle of using a drug activated by light that is connected to a site-specific marker “could be used in such cases,” he said.

While the potential bench-to-bedside process for any single treatment or approach can seem lengthy and filled with unexpected obstacles, Beutler said he has seen certain cancers that were formerly fatal yield to innovation. “People who are battling cancer can at least be hopeful that their cancer might fall into this category,” he said.

Boros appreciated the opportunity to apply for the award, to bond with her fellow finalists and to benefit from a process that included several sessions with experts at the Alan Alda Center for Communicating Science, who helped prepare her for the presentation in front of the judges. She developed her full proposal during the course of a week, over the December holiday, when her lab had some down time.

In the final stage, she met weekly for an hour with Louisa Johnson, an Improvisation Lecturer at the Alda Center and Radha Ganesan, an Assistant Professor of Medicine, to hone her presentation.

Boros said she appreciated how the Alda Center guides helped her focus on the obsession she and other scientists sometimes have of putting too much text in her slides. “I put text and conclusions on every slide,” she said. Ganesan and Johnson urged her to focus on what she wants to say, while letting go of this urge to clutter her presentation with the same words she planned to use in her presentation. “That was a huge shift in mindset that I had to make,” she said.

As for the work this prize will help fund, Boros said she’ll start with targets she knows based on some research she’s already done with prostate, breast and ovarian cancers.

Boros, who was born and raised in Switzerland, described herself as a chemist at heart.

Outside of work, she enjoys spending time with her husband Labros Meimetis, Assistant Professor of Radiology at the Renaissance School of Medicine at Stony Brook, and their nine-month-old son.

We live such a two-handed life these days. On the one hand, we are emerging from our pandemic shells. On the other, we don’t want to race out too quickly, undermining all the work we did to protect ourselves, our families and our school communities. To that end, I had a few topics on the two-handed nature of our lives:

The weather

On the one hand, it’s a relief that we can enjoy warmer weather. The summer is approaching. The calls from seagulls blend with the steady rhythm of water lapping up on the shores, urging the fortunate residents of Suffolk County to return to the peace and harmony of the water.

On the other hand, the temperature will undoubtedly climb into the hazy, hot and humid zone at some point. While the beaches are wonderful, we won’t all have time to stroll on a sandbar during the week.

Vaccinations

On the one hand, many people are getting vaccinated, increasing the likelihood that we’re taking an immunological stand against a deadly virus. With a greater percentage of the population inoculated, we stand a better chance of coming together, revisiting family and friends we’ve only seen on Zoom for over a year.

On the other hand, a subgroup of people are reluctant to take the vaccines, worried about side effects, the speed at which the vaccine was developed, and a host of other concerns. If enough of them don’t get vaccinated and/or if variants evade the vaccine, we may not be able to beat back this virus as quickly as we’d like.

Graduations

On the one hand, we are so incredibly proud that our children have made it through whatever stage concludes this year. We appreciate all they have done to get here and to become the incredible people they are.

On the other hand, wait, hello? How did the time go by so quickly? Did we prepare them for the real world? What is the real world? What does it mean to graduate into the second year of a pandemic and how can we prepare them for some of the unknowns and unknowables ahead? 

Politics

On the one hand, we can, potentially, talk about politics again without the echoes of personal animus reverberating from an angry White House. In theory, we can even agree to disagree or to consider compromise.

On the other hand, has the left become too powerful even as the right engages in party strife? Are calmer waters really around us, or is it a temporary reprieve until the tempest returns with the elections in 2022 and 2024?

Freedom

On the one hand, we are freer than we’ve been in over a year, to travel and visit family, to take our masks off outside and read people’s lips and study their smiles. We can even consider traveling outside the country.

On the other hand, after living with a fear of human contact, how much can we set aside our concerns about the public health dangers of interacting with other people? 

A return to offices

On the one hand, we have a chance to speak with each other in person, to share stories about our lives and our children and to discuss the surprising run of a Knicks team guaranteed to have a winning record this year.

On the other hand, we have to deal with traffic, parking spots, lines at lunch, and conversations that keep us from returning to the homes we couldn’t wait to leave.

Huntington Hospital scored a five-star rating from the U.S. Centers for Medicare & Medicaid Services in its annual 2021 hospital rankings.

The hospital, which is the only one in Suffolk County to achieve a five-star rating this year, has climbed the rankings over the last year, with three stars in 2019 and four stars in 2020.

“This is a reflection of the dedication of all the staff here,” said Huntington Hospital Executive Director Nick Fitterman. “What it means for the community is that they can get great care in their backyard.”

The top 13.56 percent of hospitals nationwide received five stars in 2021, according to the CMS website.

The rating measures five qualities, including mortality, safety, readmission, patient experience and timely and effective care. The first four categories receive a 22 percent weighting, while timely and effective care receives 12 percent.

The star rating encompasses over 100 measures CMS publicly reports, including the death rate for heart attack patients, surgical site infections for colon surgery, percentage of health care workers given influenza vaccinations, and the percentage of patients receiving appropriate recommendations for follow-up screening colonoscopy, among other measures.

“The five-star quality rating system is ultimately grounded in helping patients and their families make informed care decisions,” a CMS spokesman said in a statement. The ratings provide a general indication or what to expect in the future based on how a facility performed in the past.

Fitterman suggested that the rating reflects the hospital’s dedication to its mission, rather than focusing on achieving a specific rating.

Delivering excellence in clinical care is “the best and only strategy,” Fitterman said. “We don’t perseverate on what the rating agencies are looking for: we perseverate on what we think we’re doing for our patient.”

The improvements over the last few years have been incremental in numerous areas, including in neurosurgery and stroke care, cardiovascular care, and orthopedic care, which is ranked in the top 50 in the country, Fitterman said.

Fitterman praised the nursing staff, which he described as “first class,” and suggested that their culture is “contagious.”

While Huntington Hospital, which is part of Northwell Health System, doesn’t negotiate independently as a hospital, he said companies and payers “want to align themselves with high quality institutions and providers in their networks, because good [care] equates to less expensive care.”

After Fitterman received the news last week about the five stars, he walked through the hospital, high-fiving and fist pumping everyone from valets to engineers, to the food and nutrition workers and the doctors and the nurses.

“There was such excitement and jubilation and everyone realizes the hard work, the blood, sweat and tears, that go into the job,” the executive director said. “They put their heart into what they do. To get that public recognition was outstanding.”

Fitterman said he walks the halls each day, thanking staff for what they do and reminding them that they don’t just do their own task. They are all “helping relieve the suffering of others.”

By Daniel Dunaief

The waters off the South Shore of Long Island have become a magnet, attracting everything from shipping vessels, recreational boaters, fishermen and women, potential future wind farms, and humpback whales.

While the commercial component of that activity can contribute to the local economy, the whale traffic has drawn the attention of scientists and conservationists. Whales don’t abide by the nautical rules that guide ships through channels and direct traffic along the New York Bight, a region from the southern shore of New Jersey to the east end of Long Island.

Julia Stepanuk, a PhD student at Stony Brook University in the laboratory of Lesley Thorne, Assistant Professor in the School of Marine and Atmospheric Sciences, is focusing her research efforts on monitoring the humpback whale’s use of this habitat.

“This can help us understand how we focus our energy for monitoring and conservation,” she explained in an email. If the whales are traveling, it helps to know where to minimize human impact.

Ultimately, the work Stepanuk, who also earned her Master’s degree at Stony Brook in 2017, does provides ecological context for how whales use the waters around New York and how old the whales are that are feeding in this area.

In her dissertation, Stepanuk is “looking at the biological and ecological drivers, the motivators of where the whales are, when they’re there, specifically, from the lens of how human activity might be putting whales at risk of injury or mortality.”

Each summer, whales typically arrive in the area around May and stay through the end of October.

When she ventures out on the water, Stepanuk uses drones to gather information about a whale’s length and width, which indicates the approximate age and health of each individual. Since 2018, she has been gathering information to monitor activity in the area to track it over time.

With the research and data collected, she hopes to help understand the ecology of these whales, which will inform future policy decisions to manage risk.

Stepanuk’s humpback whale work is part of a 10-year monitoring study funded by the New York State Department of Environmental Conservation, which includes four principal investigators at the School of Marine and Atmospheric Sciences. The study looks at carbonate chemistry, physical oceanography, fish distribution, and top predator abundance, distribution and body condition, Thorne explained.

“My lab is leading the seabird and marine mammal aspect of this project,” said Thorne.

By documenting the ecological ranges of whales of different ages, Stepanuk may provide insight into the age groups that are most at risk. Many of the humpback whales that travel closer to shore are juveniles, measuring below about 38 feet.

Stepanuk has seen many of these whales, either directly or from the drones she flies overhead. She has also gathered information from events in which whales die after boats hit them.

Mortality events off the east coast have been increasing since 2016 as numerous whales have washed up along the coast. About half of the humpbacks in these mortality events have evidence of human interaction, either ship strike or entanglement, Stepanuk said.

“There have been many more strandings than usual of humpback whales along the east coast” in the last five years, Thorne explained.

Humpback whales likely have appeared in larger numbers in New York waterways due both to the return of menhaden in nearshore waters, which comes from changes in the management of this fish stock and from environmental management more broadly, and from an overall increase in the humpback whale population after 40 years of protection, Thorne suggested.

Ultimately, Stepanuk said she hopes to use the scientific inquiry she pursued during her PhD to help “bridge the gap between academic, policymakers, conservationists, interested parties and the public.” 

A part of Stony Brook’s STRIDE program, for science training and research to inform decisions, Stepanuk received training in science communication, how to present data in a visual and accessible way, and how to provide science-based information to policymakers.

For Thorne, this study and the analysis of the vessel strikes on humpback whales could be helpful for understanding similar dynamics with other cetaceans.

“Understanding links between large whales and vessel traffic could provide important information for other studies, and could provide methods that would be useful for studies of other species,” said Thorne.

Stepanuk offers some basic advice for people on a boat in the New York Bight and elsewhere. She suggests driving more slowly if visibility is limited, as people would in a car in foggy weather. She also urges people to pay close attention to the water. Ripples near the surface could indicate a school of fish, which might attract whales.

“Slow down if you see dolphins, big fish schools and ripples,” she said. “There’s always a chance there could be a whale.”

If people see a whale, they shouldn’t turn off their engines: they should keep the engine in neutral and not approach the whale head on or cut them off. For most species, people can’t get closer than 300 feet. For North Atlantic right whales, which are critically endangered, the distance is 1,500 feet.

She suggests people “know the cues” and remember that whales are eagerly feeding.

Stepanuk has been close enough to these marine mammals to smell their pungent, oily fish breath and, when they exhale, to receive a residue of oil around her camera lens or sunglasses. She can “loosely get an idea of what they’re feeding on in terms of how bad their breath is.”

When she was younger, Stepanuk, who saw her first whale at the age of eight, worked on a whale watching boat for six years in the Gulf of Maine. An adult female would sometimes leave her calf near the whale watching boat while she went off to hunt for food. The calf stayed near the boat for about 45 minutes. When the mother returned, she’d slap the water and the calf would race to her side.

“Experiences like that stuck with me and keep me excited about the work we do,” Stepanuk said.

Clinical Assistant Professor of Medicine at Stony Brook Medicine, Dr. Miguel Saldivar, wants residents to make vaccine decisions based on scientific information, rather than Internet speculation. Saldivar, who joined Stony Brook just months before the pandemic hit Long Island, sees improvement in the overall infection numbers, which have declined in recent weeks to about two to three percent from closer to five to six percent. In a wide-ranging interview (which can be seen online at tbrnewsmedia.com), Saldivar answered a host of questions.

TBR: Do you have any concerns about the number or percentage of people who are not lining up for vaccination?

Saldivar: In general, what we are more concerned about is the amount of misinformation that is out there. If you go on social media — if you go just on the internet, period — there’s a lot of people who are spreading lot of information that is really frankly inaccurate.

TBR: What are Stony Brook and others trying to do to counter misinformation?

Saldivar: There are a number of things we hear fairly frequently, probably the more common one I personally have heard, because Pfizer and Moderna are based on mRNA technology, everybody hears the term RNA and is worried that it’s going to change my genetic code and turn me into a mutant or cause a disease down the line. The first thing to understand about that, the way both of those vaccines work, it’s a set of instructions being given to the body cells, the moment it’s been delivered, the mRNA dissolves. It has no way of getting into the deeper part of the cells to change your genetic code.

TBR: Black and brown communities have a distrust of the federal government after some well known problems regarding Tuskegee Experiment and other issues. Is there broader acceptance now compared with a month or two ago?

Saldivar: Statistically, if you compare how this disease has affected minority communities, the risk of a severe outcome, hospitalization intubation and death is almost universally higher among minority communities. That has a number of factors, not just the disease itself. It’s also the fact that within those communities, it is more frequent to find some of the risk factors, meaning diabetes, obesity, preexisting pulmonary disease so on and so forth … What I have been personally involved with is reaching out to the community, we have found a lot of community centers have been very ready and willing to engage in a conversation. We have found places of worship to be wonderful places to have that conversation

TBR: What does the data tell you about the pandemic?

Saldivar: The last numbers I heard from the meeting this morning were between two to three percent positivity. We’ve been there for a week. Before that, we were staying pretty stable at like five to six percent or thereabouts. It looks like finally, this may be the effect of the vaccine, the numbers are finally starting to little by little trend their way down. We’ve been cautiously optimistic. There seems to be a little bit of a light at the end of the tunnel.

TBR: You have a bachelor’s degree in classical guitar performance. How did you wind up in infectious disease?

Saldivar: Through the nonprofit circle, I landed a job with the medical center at UCLA. That’s where I met a very, very good friend and mentor. She was key to helping me shape the path. I feel incredibly lucky to be part of this profession.

I have two friends whose sons are contemplating important choices. The first son, Matt, is trying to decide where to attend college.

He has gained admission to two elite schools. He can’t go wrong, as his parents have told him repeatedly, with either choice. Making this decision in a normal year would be hard. In a pandemic year, it’s almost impossible.

Matt can’t stay over at each school for a weekend or even attend a few classes. He can’t get much of a feeling for the “vibe” of the school because he can’t go into most of the buildings, even with a mask and with his letter of admission.

He can compare the national rankings from U.S. News and World Report, check college guides, talk with his guidance counselor, chat with graduates from his high school who attend each school and stroll around each campus. 

He can’t, however, fully try on the school, the way he might a tailored suit. Masks cover the faces of most of the people at each school, which makes it impossible to search for smiles on the faces of his potential future classmates.

He recently found himself leaning toward school A. The same day, his father spoke with a friend of his whose daughter was attending school B.

His father showed a picture of his friend’s daughter to Matt. The friend’s attractive daughter caused Matt to rethink his tentative decision.

That brings me to my other friend’s son, Eric. In his mid-20s, Eric has been caught in the same social world that has limited the options for everyone else.

Eric has been dating a woman for over two years and is considering the future of the relationship. He is not sure whether it’s the appropriate time to consider living together or getting married.

Eric is incredibly attached to his girlfriend, who has been one of the few people he sees regularly in real life during the pandemic.

Eric is not sure how long this altered reality, in which he works from home, speaks with family and friends virtually most of the time, and sees his girlfriend during his limited social hours, will last. In the meantime, he’d like something in his life to move forward.

Matt and Eric are weighing their options. For Matt, the choice of college may well come down to the last picture of another student he sees before he pushes a button.

Choosing a college can, and likely should, involve more significant factors. Then again, both of the colleges line up so well that he is likely to have a similar experience, albeit with different people around him, at each school.

Eric’s decision, however, isn’t so interchangeable. It involves a leap of faith that those of us who are married have made that relies on our own criteria. We can consult family, friends, and counselors as we weigh the pros and cons, but, ultimately, the responsibility and opportunity rest with us.

Coming up with his own questions and his own scale to evaluate the relationship is challenging, particularly when everything seems somewhere between good and great right now. He can’t possibly know what life will look like in two, five, 10 or 20 years from now.

I don’t envy either Matt or Eric as they contemplate these decisions. I do, however, agree with Matt’s parents: he can’t go wrong. For Eric, the decision has more significant longer-term ramifications and likely reflects variables that are difficult to imagine, particularly amid the uncertainty of the present.

Clouds are as confounding, challenging and riveting to researchers as they are magnificent, inviting and mood setting for artists and film makers.

A team of researchers at Brookhaven National Laboratory and Stony Brook University recently solved one of the many mysteries hovering overhead.

Some specific types of clouds, called mixed-phase clouds, produce considerably more ice particles than expected. For those clouds, it is as if someone took an empty field, put down enough seeds for a thin covering of grass and returned months later to find a fully green field.

Ed Luke, Atmospheric Scientist in the Environmental Sciences Department at Brookhaven National Laboratory, Andy Vogelmann, Atmospheric Scientist and Technical Co-manager of the BNL Cloud Processes Group, Fan Yang, a scientist at BNL, and Pavlos Kollias, a professor at Stony Brook University and Atmospheric Scientist at BNL, recently published a study of those clouds in the journal Proceedings of the National Academy of Sciences.

“There are times when the research aircraft found far more ice particles in the clouds than can be explained by the number of ice nucleating particles,” Vogelmann wrote in an email. “Our paper examines two common mechanisms by which the concentrations of ice particles can substantially increase and, for the first time, provides observational evidence quantifying that one is more common” over a polar site.

With a collection of theoretical, modeling and data collecting fire power, the team amassed over six years worth of data from millimeter-wavelength Doppler radar at the Department of Energy’s Atmospheric Radiation Measurement facility in the town of Utqiagvik, which was previously called Barrow, in the state of Alaska.

The researchers developed software to sort through the particles in the clouds, grouping them by size and shape and matching them with the data from weather balloons that went up at the same time. They studied the number of secondary ice needles produced under various conditions.

The scientists took about 100 million data points and had to trim them down to find the right conditions. “We culled the data set by many dimensions to get the ones that are right to capture the process,” Luke explained.

The dataset required supercooled conditions, in which liquid droplets at sub-freezing temperatures came in contact with a solid particle, in this case ice, that initiated the freezing process.

Indeed, shattering ice particles become the nuclei for additional ice, becoming the equivalent of the venture capitalist’s hoped for investment that produces returns that build on themselves.

“When an ice particle hits one of those drizzle drops, it triggers freezing, which first forms a solid ice shell around the drop,” Yang explained in a press release. “Then, as the freezing moves inward, the pressure starts to build because water expands as it freezes. That pressure causes the drizzle drop to shatter, generating more ice particles.”

Luke described Yang as the “theory wizard on the ice processes and nucleation” and appreciated the opportunity to solve the mechanism involved in this challenging problem.

“It’s like doing detective work,” said Luke. The pictures were general in the beginning and became more detailed as the group focused and continued to test them.

Cloud processes are the biggest cause for differences in future predictions of climate models, Vogelmann explained. After clouds release their precipitation, they can dissipate. Without clouds, the sunlight reaches the surface, where it is absorbed, particularly in darker surfaces like the ocean. This absorption causes surface heating that can affect the local environment.

Energy obtained from microscopic or submicroscopic processes, such as the absorption of sunlight at the molecular level or the energy released or removed through the phase changes of water during condensation, evaporation or freezing, drive the climate.

“While something at microscales (or less) might not sound important, they ultimately power the heat engine that drives our climate,” said Vogelmann.

To gather and analyze data, the group had to modify some processes to measure particles of the size that were relevant to their hypothesis and, ultimately, to the process.

“We had to overcome a very serious limitation of radar,” Kollias said. They “started developing a new measurement strategy.”

When the cost of collecting large amounts of data came down, this study, which involved collecting 500 times more data points than previous, conventional measures, became feasible.

Luke “came up with a very bright, interesting technique of how to quantitatively figure out, not if these particles are there or how often, but how many,” Kollias said.

Luke found a way to separate noise from signal and come up with aggregated statistics.

Kollias said everyone in the group played a role at different times. He and Luke worked on measuring the microphysical properties of clouds and snow. Yang, who joined over two and a half years ago and was most recently a post doctoral research associate, provided a talented theoretical underpinning, while Vogelmann helped refine the study and methodology and helped write up the ideas.

Kollias said the process begins with a liquid at temperatures somewhere between 0 and 10 degrees below zero Celsius. As soon as that liquid touches ice, it explodes, making it a hundred times more efficient at removing liquid from the cloud.

Kollias described the work as a “breakthrough” because it provided real measurements, which they can use to test their hypotheses.

In the next few months, Kollias said the group would make sure the climate modeling community sees this work.

Luke was hoping the collaboration would lead to an equation that provided the volume of secondary ice particles based on specific parameters, like temperature and humidity.

From the data they collected, “you can almost see the equation,” Luke said. “We wanted to publish the equation. That’s on the to-do list. If we had such an equation, a modeler could plug that right in.”

Even though they don’t yet have an equation, Luke said that explicit descriptions of the dataset, in the form of probability density functions, are of value to the modeling community.

The group would like to see how broadly this phenomenon occurs throughout the world. According to Kollias, this work is the “first step” and the team is working on expanding the technique to at least three more sites.

In response to the 50 mass shootings that have occurred throughout the country in the last month, the Suffolk County Police Department is enabling supermarkets and big box retailers to connect to a camera system set up to provide the police with video access to schools.

Using a resource called SHARE, which stands for Sharing to Help Access Remote Entry, businesses can plug their closed-circuit systems to the police department’s Real-Time Crime Center. The connection, which will have no cost for businesses, is designed to provide critical, up-to-the-minute information to police in the event of an active shooter.

“We know from previous active shooter events that seconds matter,” said SCPD Commissioner Geraldine Hart at a press conference on Tuesday announcing the initiative at the Suffolk County Police Department Headquarters in Yaphank. “Seconds can save lives.”

The ability to see inside a building would give the police intelligence that they could pass along to first responding officers, providing a description and updated location of a person or people who had weapons.

“One of the things that keeps me up as county executive is the idea that we could have one of these shootings here in our county in Long Island,” said County Executive Steve Bellone (D) at the press conference. The SCPD, which has been “at the forefront of efforts to address the possibility of mass shootings is, once again, announcing a continuation of these efforts.”

The collaboration between these stores and the police could go a step further, giving the police access to electronic controls that would allow them to open electronic doors remotely for emergency responders, helping them get to victims sooner and giving them a chance to maneuver around a perpetrator.

“We value partnerships with the community,” Hart said. “The goal is to keep people safe.”

Since 2016, the Suffolk County Police Department has done 420 active shooter presentations. On May 2, the SCPD will hold an active shooter drill at a King Kullen in Middle Island, which is the first time the police will conduct such an exercise in a supermarket.

The SCPD has also held 67 stop the bleed training classes for residents, which teaches people to treat wounds and practice applying tourniquets.

The SCPD will have the “ability to see inside those stores if, God forbid, an active shooter situation arises,” Bellone said.

In 2019, Bellone, Hart and Police Chief Stuart Cameron announced the SHARE program at West Babylon high school, which gave police the ability to tap into closed circuit TVs at area schools.

“This is one of the best things we can do to help save lives in an active shooter situation,” Bellone said. “We’re going to do everything we can on a local level to deal with the possibility of mass shootings.”

Bellone called the number of mass shootings in the country, which exceeds one per day, “insane,” and urged Congress to adopt “common-sense gun safety measures.” Rather than wait for a provision that might solve or prevent all the problems, Bellone urged Congress to take action immediately to reduce the risk of events that rob families and the community of loved ones amid senseless violence.

The police would only access cameras in the event of an emergency or a potentially dangerous situation.

Last month, the Village of Port Jefferson — which has had cameras hooked up to the Suffolk County Real-Time Crime Center for over two years — was able to help police find and arrest Joseph Garcia of Port Jefferson Station for the alleged shooting of David Bliss Jr. on Main Street. 

“We were proud to partner with the Suffolk County Real-Time Crime Center a few years ago to take advantage of this program that keeps our streets safe,” said Mayor Margot Garant. “It’s proven to create a quick response and help reduce crime in our village.”
