The prognosis hit Dianne Larson of Middle Island hard. Within three weeks, anxiety attacks, a lack of sleep and fear caused her weight to plummet from 135 to 120 pounds. She found out her daughter Emma, who was 17 months old at the time, had a potentially fatal genetic condition called spinal muscular atrophy in which the motor nerve cells of the spinal cord progressively weaken. Normally, the SMN1 gene produces the survival of motor neuron protein, which, as its name suggests, helps maintain motor neurons. People with SMA, which has four types and severity, produce a lower amount of the functional protein.

“My mind went to the darkest of dark places,” said Larson, whose daughter couldn’t crawl or sit up to eat. “There was no hope. There was nothing I could do.”

At the time of Emma’s diagnosis, there was no treatment for a disease that is the leading genetic cause of death among infants and affects about 1 in 10,000 newborns. Thanks to the work of Adrian Krainer, a professor and program chair of cancer and molecular biology at Cold Spring Harbor Laboratory, that changed early enough to alter the expectations for Emma and children around the world battling a genetic condition that causes progressive weakness and can make moving and even breathing difficult.

Turning to a back up gene called SMN2, Krainer hoped to fix a problem with the way that gene is spliced. On SMN2, exon 7 is normally skipped and the resulting protein has a different sequence at the end. Krainer developed an antisense olignocleotide that binds to a sequence in the intro following exon 7, blocking the splicing receptor. The treatment, which is called Spinraza, helps guide the splicing machinery, which carries out one of the steps in gene expression that is necessary to build a functional protein.

Larson had heard of Krainer’s work and was eager to see if his success with animal models of the disease would translate for humans. As soon as Emma reached her second birthday, Larson enrolled her daughter in a clinical trial for Spinraza. After her daughter had a few shots, Larson was stunned by the change. “I was in the master bedroom and she was in the den and I heard a voice getting closer,” Larson recalls. “Next thing I know, she was in my bedroom. I couldn’t believe she crawled from the den to the bedroom. I put her in the den and told her to do it again,” which she did.

The SMA community and Krainer received an early holiday present in late December when the Food and Drug Administration not only approved the treatment, but it also gave doctors the green light to prescribe it for all types of SMA and for patients of all ages. While the SMA community, doctors and Krainer have been delighted with the FDA approval, the excitement has been tempered by concerns about the price tag Biogen, which manufactures and commercializes Spinraza and funded the drug’s development, has placed on the treatment.

For the first full year of injections, the drug costs $750,000. Every year after that will cost $375,000, which Biogen has said publicly is consistent with the pricing for other drugs for so-called orphan diseases, which affect a much smaller percentage of the population.

Knowledge Ecology International, a nonprofit advocate for affordable medicines, sent a letter to the Office of the Inspector General at the Department of Health and Human Services, seeking an investigation. The letter claims that the inventor and maker of Spinraza failed to disclose that the treatment received federal funding. KEI urges the government to use that alleged disclosure failure to end the patent and authorize a generic manufacture of the treatment.

Biogen didn’t return a call and email for comment. Patients and their families, meanwhile, are looking for immediate access to a life-altering treatment. “To be honest, I really don’t know what we’re going to do,” said Larson, whose daughter has four injections left as part of the extension trial soon. “I’m hoping insurance will cover it.”

Insurer Anthem announced late in January that the treatment was only medically necessary for patients with Type 1 SMA, which include people diagnosed with the disease within six months of birth. Anthem created a pay for performance model, which will require patients or their families to prove that the treatment is improving the lives of the recipients.

Larson said she has been in touch with a personal liaison at Biogen, which has been “helpful and supportive,” she said. “They have been going out of their way to reach out to the community to make sure everyone gets access.”

Larson, who is a financial advisor, said she understands the need for the company to generate a profit. “A lot of money goes into” research and development Larson said. “If they’re not gong to make money, they’re not going to” support the efforts to create a treatment.

Joe Slay, who is the chairman of FightSMA, a group he and his wife Martha founded in 1991 after they learned their son Andrew had Type 2 SMA, sounded hopeful that people who need this treatment will receive it. “I understand there’s constructive, good conversations between insurance companies and Biogen,” Slay said. “We’re monitoring that.”

While Andrew, who is now 30, considers the potential benefits of Spinraza, Slay is pleased the treatment is an option for people and is proud of Krainer’s work.Krainer is “by any definition of the word a hero,” Slay said. “He’s taken his natural gifts, his brilliance in science, his discipline year in and year out approach to his work and has applied himself 100 percent.”

Slay and FightSMA, which has raised over $8 million since its founding, helped provide seed money to Krainer more than 15 years ago, attracting a promising scientist to what was then an intractable medical challenge.

Tom Maniatis, who is the chairman of the Department of Biochemistry and Molecular Biophysics at Columbia University, said Krainer, who did his doctoral work in Maniatis’s lab, showed considerable scientific promise early in his career. Krainer “clearly had the intelligence, drive and experimental skills to make important contributions,” Maniatis said. His work is “a perfect example of how deep basic science studies can lead to profound understanding of a disease mechanism and that, in turn to the development of a treatment,” explained Maniatis in an email.

Within Krainer’s own family, there is a connection to patient care. Krainer’s daughter Emily, who is a pediatric neurology resident at Rochester, may one day prescribe a treatment her father developed. “It will be quite something for me if she eventually prescribes Spinraza to one of her patients,” Krainer said. Even as other scientists and companies like AveXis continue to search for ways to treat SMA, Krainer enhances and refines his research.

“We continue to work on understanding aspects of SMA pathophysiology, the role of SMN levels outside the central nervous system and the potential for prenatal therapy,” he explained in an email. “We are also working on antisense therapies for other genetic diseases and cancer.”

Larson, who is overjoyed with her daughter’s progress, calls Krainer her “superhero” who “saved my daughter’s life.” “It’s such a different feeling when you know you can do something,” she said. When she found out that the FDA approved the treatment, it was “the best day.”

How is it possible that every single Democrat thinks Betsy DeVos, the newly minted secretary of education is woefully unqualified for the position and every single Republican — except for Lisa Murkowski of Alaska and Susan Collins of Maine — thinks she’s worthy of the job?

President Trump came to Washington to drain the swamp and to reinvent politics but, at least as far as DeVos goes, this seems like politics as usual. Does this vote presage an era when Republicans and Democrats will, for the most part, stick with the party line, whatever that is?

For the Democrats, is it more important to stand against a secretary the Republicans see as worthy? For the Republicans, did they not see any risk to the education system, or was it more important to stand with Trump?

This country is far from unified, as we demonstrated in November. It’s only gotten worse since then. Both sides are digging in their heels even deeper, preparing for a tug-of-war over the future of the nation.

We are living in a world of facts, alternative facts, fake news and fake tweets. The reality, however, is that we are a house divided. A 51-50 vote makes that resoundingly clear. Wasn’t it Abraham Lincoln who said that a house divided unto itself cannot stand?

Is there a middle ground? Are there ways to walk a mile in each other’s shoes, to see the world through a different perspective or, at least, to respect the process and make independent decisions?

Do we elect our officials so they’ll vote along party lines? If that’s the case, who are we electing? Shouldn’t these senators represent our interests and not demonstrate some loyalty to a party whose entire platform might not be consistent with what We the People believe?

Events in Washington are unprecedented. DeVos is in, thanks to the tiebreaker courtesy of Vice President Mike Pence who voted with his party and with his president.

If I were a political leader from my state, I might take this unprecedented period of discord and find a way to reach across the aisle to my adversaries. It’s not just for the good of the country, it would be a career maker. Imagine if a bill, a person or a policy had bipartisan support?

Suddenly, we’re not the Shepherdsons and Grangerfords, the Hatfields and McCoys, or the Montagues and the Capulets. Someone, somewhere needs to find a friend in Washington and, no, I don’t mean a dog who can co-sponsor legislation and demonstrate true leadership.

Pick an issue, any issue. Job growth? Sure, it’s one of the main items on Trump’s agenda. Education? Well, sure, that’d be nice, but we seem to have come to reached a chasm wider than the Grand Canyon with the approval of DeVos.

Maybe a Democrat and Republican can co-sponsor a way to support the military? Both sides appreciate, support and respect the men and women who protect our nation. It was also the military that beat back the guilt-by-association tactics of Republican Sen. Joseph McCarthy in the early 1950s during the Red Scare.

Let’s raise that flag together and salute the men and women we all cheer during Veterans Day parades, and who we stand and salute at sporting events for their service to our country.

These challenging times present unique opportunities. The future leaders of this nation will be the ones who can show a readiness to get along and think for themselves. A Trump presidency should free other politicians to believe in themselves and their ideas and find other leaders, even someone from the other side, to work for our common good.

It’s like that old bus riddle. The bus starts out with 20 people. Six people get off, then eight get on, two more get off, 12 enter, eight exit, and so on until, lo and behold, the bus has either the same number of people or someone asks the identity of the driver.

In this case, though, the bus is a collection of Caribbean islands called the Greater Antilles, which includes the Dominican Republic, Cuba, Hispaniola, Haiti, Puerto Rico, the Cayman Islands and Jamaica. The passengers are not people; they are species of bats.

Working with Luis Valente, a postdoctoral researcher at the Natural History Museum of Berlin, Liliana Davalos, an associate professor of conservation biology/ecology and evolution at Stony Brook University, recently determined that the number of species of bats, like the people entering and leaving the bus, remained in relative equilibrium for millions of years over many generations.

While several species of bats will colonize the islands and new species will also form over that long time scale, the rate of natural extinction in that time balances out the islands’ diversity gains, leaving the metaphorical bus with about the same number of species.

Famous biologists Edward O. Wilson and Robert MacArthur came up with the theory of island biogeography in 1967, which might help explain how the number of species of bats remained in equilibrium for millions of years. The theory proposes an equilibrium between colonization and extinction.

For bats, however, that balance changed. About 20,000 years ago, fossils of extinct species made their final appearance, while other species died off about 3,000 to 4,000 years ago. So, what happened to the bat bus?

The last ice age accounts for some of the declines about 20,000 years ago. More recently, the arrival of people altered conditions on the islands. At least two other waves of colonization occurred before the arrival of Europeans, with people changing the landscape through agriculture. While hunting of other mammals is evident from the archeological record, it is less certain how changes on the land affected bats. It’s difficult to pinpoint the exact time when each species went extinct, although many of those events happened after people arrived on the islands, changing the region’s equilibrium.

Davalos’ previous work had found that the number of species lost was as predicted if the losses occurred because of the rising sea levels at the end of the last glaciation. If that were the case, many of those species would have disappeared around that time. Some of her colleagues, however, dated the remains of bats and found that these species became extinct more recently, over the last few thousand years.

“While we cannot be certain that all bat extinctions were caused by humans, evidence increasingly seems to suggest so,” explained Valente in an email. “All over the world, colonization of islands by humans has led to many extinctions of local species, because islands have very unique species that are very prone to any disturbances.”

The researchers used computer simulations to calculate that it would take nature eight million years to restore bat biodiversity. “Some people argue that if we leave nature alone it will quickly return to its original state,” Valente explained. “However, the finding that it would take eight million years to recover lost diversity suggests that is clearly not the case.” Valente, who described Davalos as a “wonderful collaborator” who was “actively involved in the project at all stages,” wrote that this study “raises awareness for conservation of the unique bat species of the Caribbean.”

While there is still work ahead, the “nations of the Greater Antilles have amazing natural parks to protect their biodiversity,” Davalos explained. In the tropics of the Western Hemisphere, Puerto Rico is the “number one example of a forest growing back,” Davalos said. “Puerto Rico is one of the places in the world that has had more of a resurgence of the forest.”

The preservation of biodiversity remains threatened even now as at least three bat populations on the Greater Antilles are threatened with extinction and two might already be extinct. Still, the effort is not “hopeless,” she said, as there are some large populations of bats thriving on these islands. Davalos and her colleagues were able to make these discoveries by examining the bat in detail.

A resident of Setauket, Davalos has been at Stony Brook University for eight years. She enjoys kayaking on Long Island and visiting local and state parks. Over the last few years, she has spent her free time on staycations, where she sees a protected area of Long Island each day.

From a young age, Davalos recalls being interested in science. Indeed, when she was only 4, she saw a documentary where Louis and Mary Leakey showed the results of their expeditions where they collected human fossils in Kenya. “From that moment on,” Davalos recalled, “I thought, ‘Some day, this is what I’m going to study.’” Her family and their acquaintances suggested that pursuing such a career path would be challenging.

She tells her current SBU students that she’s “the luckiest person in the world, living out my childhood dream.” Last year, she went on her first fossil dig in Colombia, where she joined a team from Grand Valley State University in Allendale, Michigan, and Johns Hopkins. She found fossils from bats that were 12 million years old.

While Davalos has never met the Leakey family, she wants to tell them that, “Children are watching and [their work] can have a huge effect” on their dreams. Some day, Davalos hopes a future scientist may say the same thing about her research.

We are all proud of our children. It’s part of the perks of becoming a parent. We beam when they can walk, we celebrate what they say. We applaud their gold stars on their homework sheets, positive comments from their teachers, and their contributions to transformative musical performances that echo long in our minds.

Recently, I attended one of my daughter’s volleyball matches. She is on a new team and I didn’t know most of the other players. As soon as the first set started, it was clear that two of the girls were the leaders, covering tremendous ground to get to a ball, setting the ball from impossible distances to the net, and flying high in the air to spike a ball onto an open spot on the floor.

These two girls were inspiring their teammates with their play, even as they seemed to demand more from themselves with each set.

During the downtime between sets, parents came over to share congratulations, to offer apple slices, and to step away from the loud gym where other girls and their parents were screaming at and applauding each point.

Recognizing this will be a long season and that we’re in this together, I started chatting with several of the other parents, especially when all the children dove headlong into their cellphones during their downtime.

“My daughter is No. 7,” said a beaming woman whose daughter was about 4 inches taller than she was.

“Great,” I nodded appreciatively. “How long did it take you to drive here?”

The conversations were fairly mundane until one of the fathers of the two stronger players shared a plug to charge his iPhone.

“Your daughter is a great player,” I acknowledged.

“Thanks,” he said with a smile. “She’s a survivor.”

“Excuse me?” I asked.

“Yes, she had cancer when she was 1 year old. The pediatrician was doing a routine exam and found something. We sent her for tests and, sure enough, she had cancer.”

“Wow,” I said, stunned that the conversation wasn’t about the weather, if a ball was in or out in the last set, or what we should all do for dinner if we had to stay much longer.

“We went to a bunch of doctors and, finally, we decided to have surgery. Good thing we did, because it was malignant,” he offered.

She probably doesn’t remember it, I thought, because she was too young.

“She actually got cancer again when she was 6, and had to have surgery and chemo when they found out it was malignant again,” he said.

“She’s recovered well,” I admired.

She isn’t particularly tall, but she flies around the court, setting the ball from almost any angle without ever seeming to tire.

“Oh, yeah, well, she goes for testing regularly now, just to be sure,” he said.

She volunteers at a hospital where other children have cancer. She encourages other children and tells them that she knows how they feel. When they seem to doubt it, she shows them a copy of a picture in his wallet of his two daughters when they were 8 and 6. The older girl towers over the younger one, who is impossibly thin and bald.

Looking into this father’s face, I could see that he wasn’t only proud of the difficult journey his daughter had taken but he was inspired. So, too, as it turns out is someone else in the family.

“Yeah,” he said with a nod. “It’s why her older sister is now going to school to become a nurse.”

Watch out, Madison Avenue! People everywhere are gunning for your jobs.

Well, maybe people don’t want advertising and marketing jobs, but they do want to express themselves in ways guaranteed by the Constitution. How could the Founding Fathers have known that the war with words, on words and of words would require an ability of people on both sides to understand that each of them has a right to speak?

The Women’s March, the day after the inauguration, was a spectacle. People from around the nation, indeed the world, took considerable time to write, design and share signs about any and every issue important to them.

People are searching for the words to share their convictions.

One sign read, “Without Hermione, Harry would have died,” referring to the brilliant friend of Harry Potter whose smarts helped Harry survive despite numerous murderous attempts by Voldemort.

Another sign suggested, “So bad, even introverts are here.”

The president’s hair, a subject for television discussion well before the commander in chief left for the White House, made it onto several signs, with “We shall overcomb,” offering one of many toupee moments.

Whether the Trump administration recognizes or addresses it, we are a nation divided and, no, that’s not a statement about the size of the crowd at the inauguration. Who cares? If not a single person attended the inauguration, do you know what we would be calling Donald Trump? President.

I understand that and so do all those people writing signs, discussing the future direction of the country and arguing over the internet. I know Trump and his team seem disillusioned with the media. The president can’t stand the way he’s covered, but plenty of past presidents no doubt could relate to his discomfort.

Trump has tried to ostracize the media, going straight to the people with his creatively spelled Twitter messages.

One woman used Trump’s penchant for direct messages with a sign saying, “Tweet women with respect.”

Trump continues to make the argument about the number of people who voted for him. Can someone please tell him he won the election?

By walking side-by-side in marches, people aren’t sitting comfortably at home typing angry computer messages: They’re sharing their views and are traveling to see people “in real life.”

This is not — to borrow from Shakespeare’s “Macbeth” — “a tale told by an idiot, full of sound and fury, signifying nothing.” These are people sharing a message they hope others and, in particular, the administration, hears and understands.

Trump didn’t get to the White House propelled by the hopes of these sign makers. He won the votes of millions who believed in him.

He wants to make America great again. He and his voters have red hats to prove it. That’s great and maybe the sale of red hats will be sufficient to create more jobs, just as his office has increased the sale of poster boards, crayons, markers and block-lettering kits through these marches.

No doubt, Trump, his team and many other Americans will come up with great slogans and catchy one-liners to offset the marchers’ messages.

What will bring us together? Maybe there’ll be a moment similar to the one in the movie “Miracle,” which was about the improbable Olympics victory by the United States hockey team at Lake Placid in 1980. As these players bonded, they learned that they weren’t playing for their schools but, rather, were representing their country.

The Founding Fathers may have created a slogan that’s hard to top: We the People.

First responders, soldiers or those exposed to any kind of chemical weapons attack need a way to remove the gas from the air. While masks with activated carbon have been effective, the latest technological breakthrough involving a metal organic framework may not only remove the gas, but it could also disarm and decompose it.

That’s the recent finding from research led by Anatoly Frenkel in a study on a substance that simulates the action of sarin nerve gas.

Frenkel, who is a senior chemist at Brookhaven National Laboratory and a professor in the Department of Materials Science and Chemical Engineering at Stony Brook University, worked with metal organic frameworks, which contain zirconium cluster nodes that are connected through a lattice of organic linkages.

These structures would “do the job even without any catalytic activity,” Frenkel said, because they are porous and capture gases as they pass through them. “It’s like a sponge that can take in moisture. Its high porosity was already an asset.”

Frenkel and his colleagues, which include John Morris and Diego Troya from Virginia Tech, Wesley Gordon from Edgewood Chemical Biological Center and Craig Hill from Emory University, among other contributors, suspected that these frameworks might also decompose the gas.

Theoretically, researchers had predicted this might be the case, although they had no proof. Frenkel and his team used a differential method to see what was left in the structure after the gas passed through. Their studies demonstrated a high density of electrons near the zirconium atoms. “These were like bread crumbs congregated around a place where the zirconium nodes with the connecting linkers were,” Frenkel said.

While this work, which the scientists published in the Journal of the American Chemical Society, has implications for protecting soldiers or civilians in the event of a chemical weapons attack, Frenkel and his colleagues, who received funding from the Defense Threat Reduction Agency, can share their results with the public and scientific community because they are not working on classified materials and they used a substance that’s similar to a nerve gas and not sarin or any other potentially lethal gas.

“This knowledge can be transferred to classified research,” Frenkel said. “This is a stepping stone.” Indeed, Frenkel can envision the creation of a mask that includes a metal organic framework that removes deadly nerve gases from the air and, at the same time, disarms the gas, providing a defense for first responders or the military after a chemical weapons attack. Even though he doesn’t work in this arena, Frenkel also described how manufacturers might use these frameworks in treating the fabric that is used to make clothing that can prevent gases that can be harmful to the skin from making contact.

A physicist by training, Frenkel’s work, which includes collaborations on five other grants, has a common theme: He explores the relationship between structure and function, particularly in the world of nanomaterials, where smaller materials with large surface areas have applications in a range of industries, from storing and transmitting energy to delivering drugs or pharmaceuticals to a targeted site.

Eric Stach, a group leader in electron microscopy at BNL, has collaborated with Frenkel and suggested that his colleague has helped “develop all these approaches for characterizing these materials.” Stach said that Frenkel has “an outstanding reputation internationally” as an expert in X-ray absorption spectroscopy, and, in particular, a subarea that allows scientists to learn about extremely subtle changes in the distance between atoms when they are subjected to reactive environments.

Frenkel said some of the next steps in the work with metal organic frameworks include understanding how these materials might become saturated with decomposed gas after they perform their catalytic function. “It’s not clear what can affect saturation,” he said, and that is something that “needs to be systematically investigated.” After the catalyst reaches saturation, it would also be helpful to know whether it’s possible to remove the remaining compound and reuse the catalyst.

“The next question is whether to discard” the framework after it’s trapped and deactivated the chemicals or regenerate it, Frenkel said. He is also exploring how temperature ranges might affect the performance of the framework. Ideally, it would function as well in an arctic environment as it would in a desert under extreme heat. A commercial application might require the synthesis of a material with different physical characteristics for a range of temperature conditions.

Frenkel has been working on this project for about one and a half years. A colleague approached him to become a part of this new collaboration. “My role was to bring this work to a national lab setting,” where the scientists could use the advanced tools at BNL to study the material as it was working, he said.

A resident of Great Neck, Frenkel, who grew up in St. Petersburg, Russia, lives with his wife Hope Chafiian, a teacher at the Spence School in Manhattan for almost 30 years. He has three children: Yoni lives in Manhattan and works at JP Morgan Chase, Ariela is a student at Binghampton and Sophie is in middle school in Great Neck.

Frenkel appreciates the opportunity to explore the broader world of nanomaterials, which, he said, are not constrained by crystal structures and can be synthesized by design. “They show a lot of mysteries that are not understood fully,” he said. Indeed, Frenkel explained that there are numerous commercial processes that might benefit from design studies conducted by scientists. As for his work with metal organic frameworks, he said “there’s no way to overestimate how important [it is] to do work that has a practical application that improves technology, saves costs, protects the environment” and/or has the potential to save lives.

I’m a coach for a boys’ basketball team. I want to win every game because that’s what America is all about — winning. I want to make my team great again, because we haven’t been as great as we’d like to be and that’s not acceptable.

Now, I know there are parents on this team and the other team who find my methods and my approach worrisome. Don’t. I’m going to win and that’ll be great and I have a plan. No, I’m not going to share it with you and, no, just because you heard some things about me doesn’t mean they’re true.

Who’s telling you all those things? Do you believe any of them? Well, you shouldn’t, because I don’t. I have plenty of people who are eager to tell you how great I am. There’s a woman with blonde hair who I can put in front of you who will make sure you understand what I mean when I say what I say.

Well, I don’t always say anything. I prefer to tweet, particularly about the other team. You see that other coach the other day? I heard someone, and mind you it wasn’t me, suggest that he might not have been born in the United States.

Yes, I know he’s still allowed to coach here and, yes, I know there are plenty of incredibly important people who came to the U.S. and contributed greatly to the founding, establishment and greatness of this country. That’s not the point. The point is that I want to win and be great and greatness comes from here, and not from over there. If you can’t tell, I’m pointing to the fertile, rich, wonderful soil beneath my feet. Well, no, actually, I’m not pointing to the soil. I’m pointing at my expensive shoes. You want greatness? You need nice shoes.

Speaking of nice shoes, did you see the shoes that one of the moms wore to the game the other day? Wait, what? I’m not allowed to notice beautiful women and their nice shoes now? That’s not fair. If they wear the shoes, I should be able to notice them. I notice the nice shoes my daughter, Danika, wears and they make her feet look magnificent. I’m so proud of those shoes and those feet.

Oh yes, I heard that other coach saying things about me behind my back while I was looking at him and he was speaking to me. How dare he say things that didn’t support me. He should be locked up.

If I were on Twitter right now, I’d say he was wrong! I might spell it incorrectly because my mistakes give my opponents, who I trounce like sad little bugs, something to talk about when they’re trying to get in the way of my greatness.

So, here we are at the game. It’s finally starting. The referees look shifty to me. Who wears black and white? Is that some kind of politically correct statement? It didn’t work for Seinfeld when he had that black-and-white cookie episode. He got sick. Remember that? Ah, TV. Isn’t it awesome?

Anyway, so we need to win the game and we need to make sure the other team loses. I’m going to win because I know things other people don’t and I’m “marts.” You see? I had a deliberate misspelling there, putting the “s” in the wrong place.

Now that the game has ended, I’m disappointed in everyone. The refs? Rigged! The other coach? Ridiculous! The fans? Well, what do the ones who complain know anyway?

I know I won, but that’s besides the point. I want the losers to know that they’re losers, even though they can be great someday, too, if they listen to me.

By Daniel Dunaief

Before Ernest Moniz ends his tenure as Secretary of the Department of Energy, he and his department released the first annual report on the state of the 17 national laboratories, which include Brookhaven National Laboratory.

On a recent conference call with reporters, Moniz described the labs as a “vital set of scientific organizations” that are “critical” for the department and the country’s missions. Experts from the labs have served as a resource for oil spills, gas leaks and nuclear reactor problems, including the meltdown at Fukushima in 2011 that was triggered by a deadly tsunami. “They are a resource on call,” Moniz said.

In addition to providing an overview of the benefit and contribution of the labs as a whole, the annual report also offered a look at each of the labs, while highlighting a research finding and a translational technology that has or will reach the market. In its outline of BNL, the report heralded an “exciting new chapter of discovery” triggered by the completion of the National Synchrotron Light Source II, a facility that allows researchers at BNL and those around the world who visit the user facility to explore a material’s properties and functions with an incredibly fine resolution and sensitivity.

Indeed, scientists are already exploring minute inner workings of a battery as it is operating, while they are also exploring the structure of materials that could become a part of new technology. The DOE chose to shine a spotlight on the work Ralf Seidl, a physicist from the RIKEN-BNL Research Center, has done with several collaborators to study a question best suited for answers at the Relativistic Heavy Ion Collider.

Seidl and his colleagues are exploring what gives protons their spin, which can affect its optical, electrical and magnetic characteristics. The source of that spin, which researchers describe not in terms of a top spinning on a table but rather as an intrinsic and measurable form of angular momentum, was a mystery.

Up until the 1980s, researchers believed three subatomic particles inside the proton created its spin. These quarks, however, only account for a third of the spin. Using RHIC, however, scientists were able to collide protons that were all spinning in a certain direction when they smash into each other. They compared the results to protons colliding when their spins are in opposite directions.

More recently, Seidl and his colleagues, using higher energy collisions, have been able to see the role the gluons, which are smaller and hold quarks together, play in a proton’s spin. The gluons hadn’t received much attention until the last 20 years, after experiments at CERN, in Geneva, demonstrated a lower contribution from quarks. “We have some strong evidence that gluons play a role,” Seidl said from Japan, where he’s working as a part of an international collaboration dedicated to understanding spin.

Smaller and more abundant than quarks, gluons are like termites in the Serengeti desert in Africa: They are hard to see but, collectively, play an important role. In the same report, the DOE also celebrated BNL’s work with fuel cell catalysts. A senior chemist at BNL, Radoslav Adzic developed a cheaper, more effective nanocatalyst for fuel cell vehicles. Catalysts for fuel cells use platinum, which is expensive and fragile. Over the last decade, Adzic and his collaborators have developed a one-atom-thick platinum coating over cheaper metals like palladium. Working with BNL staff scientists Jia Wang, Miomir Vukmirovic and Kotaro Sasaki, he developed the synthesis for this catalyst and worked to understand its potential use.

N.E. Chemcat Corporation has licensed the design and manufacturing process of a catalyst that can be used to make fuel cells as a part of a zero-emission car. This catalyst has the ultra low platinum content of about two to five grams per car, Adzic said. Working at BNL enabled partnerships that facilitated these efforts, he said. “There is expertise in various areas and aspects of the behavior of catalysts that is available at the same place,” Adzic observed. “The efficiency of research is much more convenient.”

Adzic, who has been at BNL for 24 years, said he has been able to make basic and applied research discoveries through his work at the national lab. He has 16 patents for these various catalysts, and he hopes some of them will get licensed. Adzic hopes this report, and the spotlight on his and other research efforts, will inspire politicians and decision makers to understand the possibility of direct energy conversion. “There are great advances in fuel cell development,” Adzic said. “It’s at the point in time where we have to do some finishing work to get a huge benefit for the environment.”

At the same time, the efficiency of fuel-cell-powered vehicles increases their economic benefit for consumers. The efficiency of an internal combustion engine is about 15 percent, whereas a fuel cell has about 60 percent efficiency, Adzic said.

BNL’s Laboratory Director Doon Gibbs welcomed the DOE publication. “This report highlights the remarkable achievements over the past decade of our national lab system — one that is unparalleled in the world,” he said. Gibbs suggested that the advanced details in the report, including the recognition for the NSLS II, span the breadth of BNL’s work. “They’re just a snapshot of what we do every day to make the world a better place,” Gibbs said.

While the annual report is one of Moniz’s final acts as the secretary of the agency, he hopes to communicate the vitality and importance of these labs and their work to the next administration.“I will be talking more with secretary nominee [Richard] Perry about the labs again as a critical jewel and resource,” Moniz said. “There’s a lot of support in Congress.” Moniz said the DOE has had five or six lab days, where labs share various displays with members of the legislative body. Those showcases have been “well-received” and he “fully expects the labs to be vital to the department.”

Born in Berlin just before World War II, Eckard Wimmer has dedicated himself in the last 20 years to producing something that would benefit humankind. A distinguished professor in molecular genetics and microbiology at Stony Brook University, Wimmer is hoping to produce vaccines to prevent the spread of viruses ranging from influenza, to Zika, to dengue fever, each of which can have significant health consequences for people around the world.

Using the latest technology, Wimmer, Steffen Mueller and J. Robert Coleman started a company called Codagenix in Melville. They aim to use software to alter the genes of viruses to make vaccines. “The technology we developed is unique,” said Wimmer, who serves as senior scientific advisor and co-founder of the new company.

Mueller is the president and chief science officer and Coleman is the chief operating officer. Both worked for years in Wimmer’s lab. Despite the potential to create vaccines that could treat people around the world facing the prospect of debilitating illnesses, Wimmer and his collaborators weren’t able to attract a pharmaceutical company willing to invest in a new technology that, he estimates, will take millions of dollars to figure out its value.“Nobody with a lot of money may want to take the risk, so we overcame that barrier right now,” he said.

Codagenix has $6.2 million in funding. The National Institutes of Health initially contributed $600,000. The company scored an additional $1.4 million from NIH. It also raised $4.2 million from venture capital, which includes $4 million from TopSpin and $100,000 from Accelerate Long Island and a similar amount from the Center for Biotechnology at Stony Brook University.

Stony Brook University recently entered an exclusive licensing agreement with Codagenix to commercialize this viral vaccine platform. Codagenix is scheduled to begin phase I trials on a vaccine for seasonal influenza this year.

The key to this technology came from a SBU collaboration that included Wimmer, Bruce Futcher in the Department of Molecular Genetics & Microbiology and Steven Skiena in the Department of Computer Science. The team figured out a way to use gene manipulation and computer algorithms to alter the genes in a virus. The change weakens the virus, giving the attack dog elements of the immune system a strong scent to seek out and destroy any real viruses in the event of exposure.

Wimmer explained that the process starts with a thorough analysis of a virus’s genes. Once scientists determine the genetic code, they can introduce hundreds or even thousands of changes in the nucleic acids that make up the sequence. A computer helps select the areas to alter, which is a rapid process and, in a computer model, can take only one afternoon. From there, the researchers conduct experiments in tissue culture cells and then move on to experiment on animals, typically mice. This can take six months, which is a short time compared to the classical way, Wimmer said.

At this point, Codagenix has a collaboration with the Universidad de Puerto Rico at the Caribbean Primate Research Center to treat dengue and Zika virus in primates. To be sure, some promising vaccines in the past have been taken off the market because of unexpected side effects or even because they have become ineffective after the virus in the vaccine undergoes mutations that return it to its pathogenic state. Wimmer believes this is unlikely because he is introducing 1,000 changes within a vaccine candidate, which is much higher than other vaccines. In 2000, for example, it was discovered that the polio vaccines involve only five to 50 mutations and that these viruses had a propensity to revert, which was rare, to the type that could cause polio.

Colleagues suggested that this technique was promising. “This approach, given that numerous mutations are involved, has the advantage of both attenuation and genetic stability of the attenuated phenotype,” Charles Rice, the Maurice R. and Corrine P. Greenberg professor in virology at Rockefeller University explained in an email.

While Wimmer is changing the genome, he is not altering the structure of the proteins the attenuated virus produces, which is exactly the same as the virus. This gives the immune system a target it can recognize and destroy that is specific to the virus. Wimmer and his associates are monitoring the effect of the vaccines on mosquitoes that carry and transmit them to humans. “It’s not that we worry about the mosquito getting sick,” he said. “We have to worry whether the mosquito can propagate this virus better than before.” Preliminary results show that this is not the case, he said.

Wimmer said there are many safety precautions the company is taking, including ensuring that the vaccine candidate is safe to administer to humans. Wimmer moved from Berlin to Saxony after his father died when Wimmer was 3. He earned an undergraduate degree in chemistry in 1956 at the University of Rockstock. When he was working on his second postdoctoral fellowship at the University of British Columbia in Vancouver, he heard a talk on viruses, which brought him into the field.

A resident of Old Field, Wimmer lives with his wife Astrid, a retired English professor at Stony Brook. The couple’s daughter Susanne lives in New Hampshire and has three children, while their son Thomas lives in Portland, Oregon, and has one child. “We’re very happy Long Islanders,” said Wimmer, who likes to be near the ocean and Manhattan.

Through a career spanning over 50 years, Wimmer has won numerous awards and distinctions. He demonstrated the chemical structure of the polio genome and worked on polio pathogenesis and human receptor for polio. He also published the first cell-free creation of a virus.

“This was an amazing result that enabled a number of important mechanistic studies on poliovirus replication,” Rice explained. Wimmer has “always been fearless and innovative, with great enthusiasm for virology and discovery.”

With this new effort, Wimmer feels he will continue in his quest to contributing to humanity.

Pop them in the back of a cell phone and they work, most of the time. Sometimes, they only do their job a short time, discharge or generate so much heat that they become a hazard, much to the disappointment of the manufacturers and the consumers who bought electronic device.

Esther Takeuchi, a SUNY distinguished professor in the Departments of Chemistry and Materials Science and Engineering and the chief scientist in the Energy Sciences Directorate at Brookhaven National Laboratory leads a team of scientists who are exploring what makes one battery work while another falters or fails. She is investigating how to improve the efficiency of batteries so they can deliver more energy as electricity.

The process of manufacturing batteries and storing energy is driven largely by commercial efforts in which companies put the ingredients together in ways that have, up until now, worked to produce energy. Scientists like Takeuchi, however, want to know what’s under the battery casing, as ions and electrons move beneath the surface to create a charge.

Recently, Takeuchi and a team that includes her husband Kenneth Takeuchi and Amy Marschilok, along with 18 postdoctoral and graduate students, made some progress in tackling energy storage activity in iron oxides.

These compounds have a mixed track record among energy scientists. That, Takeuchi said, is what attracted her and the team to them. Studying the literature on iron oxides, her graduate students discovered “everything from, ‘it looks terrible’ to, ‘it looks incredibly good,’” she said. “It is a challenging system to study, but is important to understand.”

This offered promise, not only in finding out what might make one set of iron oxides more effective in holding a charge without generating heat — the energy-robbing by-product of these reactions — but also in providing a greater awareness of the variables that can affect a battery’s performance.

In addition to determining how iron oxides function, Takeuchi would like to “determine whether these [iron oxides] can be useful and workable.” Scientists working with iron oxides didn’t know what factors to control in manufacturing their prospective batteries.

Takeuchi said her group is focusing on the linkage between small-scale and mesoscale particles and how that influences battery performance. “The benefit of iron oxides is that they are fairly inexpensive, are available, and are nontoxic,” she said, and they offer the potential of high energy content. They are related to rust in a broad sense. They could, theoretically, contain 2.5 times more energy than today’s batteries. “By understanding the fundamental mechanisms, we can move forward to understand their limitations,” she said, which, ultimately, could result in making these a viable energy storage material. T

akeuchi is also looking at a manganese oxide material in which the metal center and the oxygen connect, creating a tube-like structure, which allows ions to move along a track. When she started working with this material, she imagined that any ion that got stuck would cause reactions to stop, much as a stalled car in the Lincoln Tunnel leads to long traffic delays because the cars behind the blockage have nowhere to go.

Takeuchi said the ions don’t have the same problems as cars in a tunnel. She and her team believe the tunnel walls are porous, which would explain why something that looks like it should only produce a result that’s 5 percent different instead involves a process that’s 80 percent different. “These escape points are an interesting discovery, which means the materials have characteristics that weren’t anticipated,” Takeuchi said. The next step, she said, is to see if the researchers can control the technique to tune the material and make it into the constructs that take advantage of this more efficient flow of ions.

Through a career that included stops in Buffalo and North Carolina and West Virginia, Takeuchi, who has over 150 patents to her name, has collected numerous awards and received considerable recognition. She won the 2009 National Medal of Technology and Innovation, a presidential award given at a ceremony in the West Wing of the White House. Takeuchi developed compact lithium batteries for implantable cardiac defibrillators.

Takeuchi is currently a member of the National Medal of Technology and Innovation Nomination Evaluation Committee, which makes recommendations for the medal to the president. Scientists who have known Takeuchi for years applaud the work she and her team are doing on Long Island. “Dr. Takeuchi and her research group are making great advances in battery research that are very clearly promoted by the strong relationship between Stony Brook and BNL,” said Steven Suib, the director of the Institute for Materials Science at the University of Connecticut.

Indeed, at BNL, Takeuchi has used the National Synchrotron Light Source II, which became operational last year. The light source uses extremely powerful X-rays to create incredibly detailed images. She has worked with three beamlines on her research. At the same time, Takeuchi collaborates with researchers at the Center for Functional Nanomaterials at BNL.

Although she works with real-world experiments, Takeuchi partners with scientists at Stony Brook, BNL and Columbia University who focus on theoretical possibilities, offering her an insight into what might be happening or be possible. There are times when she and her team have observed some interaction with batteries, and she’s asked the theorists to help rationalize her finding. Other times, theorists have suggested what experimentalists should search for in the lab.

A resident of South Setauket, Takeuchi and her husband enjoy Long Island beaches. Even during the colder weather, they bundle up and enjoy the coastline. “There’s nothing more mentally soothing and energizing” than going for a long walk on the beach, she said.

In her research, Takeuchi and her team are focused on understanding the limitations of battery materials. Other battery experts believe her efforts are paying dividends. Suib said the recent work could be “very important in the development of new, inexpensive battery materials.”
