Ferdinand Magellan didn’t have the luxury of sending a machine into the unknown around the world before he took to the seas. Modern humans, however, dispatch satellites, rovers and orbiters into the farthest reaches of the universe. Several months after the New Horizons spacecraft beamed back the first close-up images of Pluto from over three billion miles away, NASA confirmed the presence of water on Mars.

The Mars discovery continues the excitement over the possibility of sending astronauts to the Red Planet as early as the 2030s.

Before astronauts can take a journey between planets that average 140 million miles apart, scientists need to figure out the health effects of prolonged exposure to damaging radiation.

Each year, liaison biologist Peter Guida at the NASA Space Radiation Laboratory (NSRL) at Brookhaven National Laboratory coordinates the visits of over 400 scientists to a facility designed to determine, among other things, what radiation does to the human body and to find possible prevention or treatment for any damage.

Guida is working to “improve our understanding of the effects that space radiation from cosmic rays have on humans,” explained Michael Sivertz, a physicist at the same facility. “He would like to make sure that voyages to Mars do not have to be one-way trips.”

Guida said radiation induces un-repaired and mis-repaired DNA damage. Enough accumulated mutations can cause cancer. Radiation also induces reactive oxygen species and produces secondary damage that is like aging.

The results from these experiments could provide insights that lead to a better understanding of diseases in general and may reveal potential targets for treatment.

This type of research could help those who battle cancer, neurological defects or other health challenges, Guida said.

By observing the molecular changes tissues and cells grown in the lab undergo in model systems as they transition from healthy to cancerous, researchers can look to protect or restore genetic systems that might be especially vulnerable.

If the work done at the NSRL uncovers some of those genetic steps, it could also provide researchers and, down the road, doctors with a way of using those genes as predictors of cancer or can offer guidance in tailoring individualized medical treatment based on the molecular signature of a developing cancer, Guida suggested.

Guida conducts research on neural progenitor cells, which can create other types of cells in the nervous system, such as astrocytes. He also triggers differentiation in these cells and works with mature neurons. He has collaborated with Roger M. Loria, a professor in microbiology and immunology at Virginia Commonwealth University, on a compound that reverses the damage from radiation on the hematological, or blood, system.

The compound can increase red blood cells, hemoglobin and platelet counts even after exposure to some radiation. It also increases monocytes and the number of bone marrow cells. A treatment like this might be like having the equivalent of a fire extinguisher nearby, not only for astronauts but also for those who might be exposed to radiation through accidents like Fukushima or Chernobyl or in the event of a deliberate act.

Loria is conducting tests for Food and Drug Administration approval, Guida said.

If this compound helps astronauts, it might also have applications for other health challenges, although any other uses would require careful testing.

While Guida conducts and collaborates on research, he spends the majority of his time ensuring that the NSRL is meeting NASA’s scientific goals and objectives by supporting the research of investigators who conduct their studies at the site. He and a team of support personnel at NSRL set up the labs and equipment for these visiting scientists. He also schedules time on the beam line that generates ionizing particles.

Guida is “very well respected within the space radiation community, which is why he was chosen to have such responsibility,” said Sivertz, who has known Guida for a decade.

Guida and his wife Susan, a therapist who is in private practice, live in Searingtown.

While Guida recalls making a drawing in crayon after watching Neil Armstrong land on the moon, he didn’t seek out an opportunity at BNL because of a long-standing interest in space. Rather, his scientific interest stemmed from a desire to contribute to cancer research.

When he was 15, his mother Jennie, who was a seamstress, died after a two-year battle with cancer. Guida started out his career at Cold Spring Harbor Laboratory, where he hoped to make at least the “tiniest contribution” to cancer research.

He pursued postdoctoral research at BNL to study the link between mutations, radiation and cancer.

Guida feels as if he’s contributed to cancer research and likes to think his mother is proud of him. “Like a good scientist,” though, he said he’s “never satisfied. Good science creates the need to do more good science. When you find something out, that naturally leads to more questions.”

Sleeping doesn’t just provide a break from the daily grind, prevent you from chowing down on more Oreo cookies, or keep you out of trouble when it gets dark. It may also serve an important brain-cleaning function, getting rid of tau and beta amyloid proteins.

Merely shutting your eyes and letting the sandman sprinkle dust on your forehead may not be enough. You might actually help your brain, over the long term, with the way you sleep.

Helene Benveniste, a professor of anesthesiology and radiology and vice chair for research in the Department of Anesthesiology at Stony Brook University, recently conducted research on anesthetized rodents, tracking how the glymphatic system worked in various sleep positions. The animals were better at flushing tau and beta amyloid proteins from their brains when they slept laterally, or on their sides, than when they slept on their stomachs. Resting on their backs wasn’t as efficient as sleeping on their sides, although it was better than face down.

These proteins aren’t just a part of everyday maintenance. They likely play a role in the onset of Alzheimer’s disease and other age-related neurological problems, Benveniste said.

Since Benveniste published her study in the Journal of Neuroscience in early August, she has received a flood of emails from around the world, including from Brazil, France and Colombia, with people asking about various sleep positions and neurological disorders.

The Stony Brook professor said it is too soon after this study to come to any conclusions about sleep or preventing cognitive disorders. For starters, she and a research team that included scientists at the University of Rochester, NYU Langone Medical Center and Stony Brook conducted the studies on animal models, rather than on humans.

“In general, the rodent is a pretty good model for core aspects of human brain function,” said Dennis Choi, the chairman of the Neurology Department at Stony Brook. The specifics, however, can differ from one species to another. As a result, Benveniste said, “I don’t think anybody should panic” about the way he or she sleeps.

Scientists know that in the glymphatic pathway, cerebrospinal fluid moves through the brain and exchanges with interstitial fluid to get rid of waste. In the studies with rodents, the face down position seemed to divert the cerebrospinal fluid away from the brain, Benveniste said.

The research could be another step toward understanding how sleep might help with the human glymphatic system.

An anesthesiologist who does clinical work one day a week, Benveniste said she started thinking about conducting this kind of study a few years ago. Benveniste is a “good example of a physician/scientist,” Choi said.

Two years ago, a study by a co-author on the paper, Maiken Nedergaard from the University of Rochester, showed that sleep or general anesthesia enhances the clearance of waste from the brain of rodents.

“Since I am an anesthesiologist, I immediately thought about how body/head positions during anesthesia might affect clearance,” Benveniste said. The data took over a year and a half to collect and analyze.

“The quantitative aspect of this system should not be overlooked. To find out how these [proteins] are moving through the brain is a huge issue,” she said. The collaboration with Jean Logan, senior research scientist in the Department of Radiology at NYU “enabled us to move forward.”

Benveniste used a dynamic contrast MRI method to calculate the exchange rates between the cerebrospinal fluid and the interstitial fluid. The next step in these studies is to move toward the human brain. Benveniste said she is working with colleagues at the National Institutes of Health.

Just from observing wildlife outside the lab, Benveniste said many animals tend to sleep in what she and her team found was the optimum position for clearing waste in rodents: on their sides. “Even elephants lie down in recumbent, lateral positions,” she added.

As for Benveniste, she said she naturally sleeps on her right side. She said she’s well aware of how well she slept during the night. If she wakes up after getting enough rest, she said she thinks, “this was a good night’s sleep. This was good for my brain.”

Benveniste, who lives in Northport with her husband, Peter Huttemeier, is also an advocate of exercise for brain health, although she doesn’t suggest marathon running. “I do think this may be affecting the cerebrospinal fluid flow dynamics,” she said, adding that she wants to take up yoga.

Benveniste is eager to continue to build on this sleep study. “The workings of this system so far has been an amazing exploratory adventure,” she said.

If the smartest people in the world gathered in a room, they might struggle to collaborate. An Australian astrophysicist might have a different way of solving problems from the Spanish sociologist. That doesn’t even address language barriers.

Similar principles hold true for the world’s best super computers. While each may have an ability to perform numerous calculations, gather information, and extrapolate from patterns too complicated to discover with a pencil and paper, they can be limited in their ability to work together efficiently.

That’s where a leader in the field of parallel computing comes in. Barbara Chapman, who has been at the University of Houston since 1999, has taught rising stars in the field, written textbooks and enabled the combination of supercomputers to become more than the proverbial sum of their parts.

And, this week, she is bringing her talents to Long Island, where she’s starting the next step in her career as a professor of Applied Math and Statistics, and Computer Science at Stony Brook, as part of the Institute for Advanced Computational Science and as an affiliate at Brookhaven National Laboratory.

Calling Chapman a “pioneer in the world of parallel computing,” Sunita Chandrasekaran, who was a post-doctoral researcher in Chapman’s lab, predicted Chapman would “attract top graduate students from across the globe. Many students would love to do research under Chapman’s supervision.”

Lei Huang, an assistant professor in the computer science department at Prairie View A&M University in Texas, considers Chapman his “mentor,” and said she is “always patient with students,” making her a “valuable asset” to Stony Brook. Huang, who did his Ph.D. and worked as a post doc in Chapman’s lab, added that she proposed and implemented innovative language features to improve performance and productivity of programming on supercomputers.

Chapman, who grew up in New Zealand, said she left the more temperate region of Houston driven, in part, by the intelligence and personality of Robert J. Harrison, Stony Brook’s director for the Institute for Advanced Computational Science. Additionally, Chapman sees opportunities to work with local collaborators.

Chapman works to make it easier for scientists and other users to get computers to solve their problems and gain insights from massive amounts of data. She strives to get high-powered computers to work together efficiently.

Scientists need to give computers a way of telling the cores how to interact and collaborate. Dividing up the work and ensuring that these computers share data are among the challenges of her role.

The new Stony Brook scientist helped develop OpenMP, which can be used to program multicores and is an industry standard used in cell phones, among other things.

President Obama unveiled plans to build an exascale computer, which might be capable of performing a billion billion operations per second. Building this computer will have numerous challenges, including hardware, power, memory, data movement, resilience and programming.

Chandrasekaran, who recently joined the University of Delaware as an assistant professor, said software programming needs to be more intuitive, portable across platforms and adaptable without any compromise in performance. Chapman, she said, is a leader in these fields, bringing together national laboratories, vendors and academia.

As a part of a group of researchers asked to identify opportunities for collaborations between the United States and Egypt, Chapman also journeyed to Egypt. While it was a “wonderful experience,” Chapman said the efforts were put on hold indefinitely after the revolution.

Applications that exploit supercomputers range from astrophysics to the automotive industry to analyzing old texts, to determine if the works of classical scholars were written or translated by the same person, Chapman said.

Chapman and her colleagues work to design features to support the next generation of computers. In the next few years, Chapman expects computers to have more complex memory, while the cores will be more heterogeneous.

At the same time, hardware manufacturers are focused on green computing, enabling the same computing power while using less energy.

Chapman enjoys working in an academic setting, where she can inspire the next generation of computer scientists. She will start teaching at Stony Brook in 2016.

While Chapman’s work centers around helping computers get the most from their collaborations, she also believes the workforce would benefit from attracting, training and supporting people from a broader range of backgrounds, including African-Americans, Hispanics, and women.

“If we had a much more diverse group of people, how would our use of computers change?” she asks. “Would we find other uses of computers?”

Chapman is encouraged that her concern about diversity is a matter numerous people in Washington are discussing. “I chaired a small study on this last year for the Department of Energy,” she said. “There’s a lot of buy-in to the notion that it’s important to change that.”

Chapman said an early experience working with the National Aeronautics and Space Administration ignited her interest in computer science. She worked with people who were exploring what happens when a spacecraft re-enters Earth’s atmosphere. They were designing materials that are better able to withstand the heat and speed of returning to Earth.

“People can use machines for finding out what’s going on in the universe in the big picture,” she said. “That got me hooked.”

It’s a dangerous enemy that often turns deadly. Worse than its potentially lethal nature, however, cancer has an ability to work around any roadblocks scientists and doctors put in its path, rendering some solutions that bring hope ineffective.

Researchers around the world are eagerly searching for ways to stay one, two or three moves ahead of cancer, anticipating how the many forms of this disease take medicine’s best shot and then go back to the business of jeopardizing human health.

Allen Tannenbaum, a professor of computer science and applied mathematics and statistics at Stony Brook University, has added a field called graph theory to some of the tools he knows well from his work in medical imaging and computer vision.

A normal, healthy cell is like a factory, with genes sending signals through proteins, enzymes and catalysts, moving reactions forward or stopping them, and the genetic machinery indicating when and how hard the parts should work.

Cancer, however, is like a hostile takeover of that factory, producing the factory equivalent of M16s that damage the cell and the individual instead of baby toys, Tannebaum suggested.

By analyzing how proteins or transcription networks interact, Tannenbaum and his colleagues can develop a model for the so-called curvature of interactions.

Looking at the interactions among parts of the genetic factory, Tannenbaum can determine and quantify the parts of the cell that are following cancer commands, rather than doing their original task.

Curvature isn’t so much a bending of a physical space as it is a change in the way the different proteins or transcription factors function in the discrete networks Tannenbaum uses in cancer and biology.

“The parts are not doing their job the same way,” Tannenbaum said. “We can look and see graphically how different things compare.” He and his collaborators recently published their findings in the journal Scientific Reports.

Using mathematical formulas to define a range of interactions, Tannenbaum can determine how quickly a cancer or normal cell can return to its original state after a disturbance. This ability is called its robustness.

The study “brings to light a new way to understand and quantify the ability of cancer cells to adapt and develop resistance,” explained Tryphon T. Georgiou, a professor in the Department of Electrical and Computer Engineering at the University of Minnesota, who has known Tannenbaum for over 30 years and collaborated on this study. “It also provides ways to identify potential targets for
drug development.”

Tannenbaum studied cells from six different tumor types and supplemented the study with networks that contain about 500 cancer-related genes from the Cosmic Cancer Gene Census.

In treatments for cancers, including sarcomas, researchers and doctors sometimes try to pull the plug on cancer’s energy network. This method can slow cancer down, but cancer often resumes its harmful operations.

Using models of cancer on a computer, Tannenbaum and the five graduate students and four postdoctoral fellows can run virtual experiments. He can hand off his results to biologists, who can then run tests. Once those scientists collect data, they can offer information back to Tannenbaum.

“This is a team effort,” said Tannenbaum, who works with scientists at Memorial Sloan Kettering, the University of Texas MD Anderson Cancer Center and Brigham and Women’s Hospital.

Georgiou described Tannenbaum as a “brilliant scholar” and a “mathematician with unparalleled creativity,” who has been a “pioneer in many fields,” including computer vision. Indeed, a computer vision program could assist nurses in the intensive care unit on different shifts assess the level of pain from someone who might not otherwise be able to communicate it.

Georgiou called Tannenbaum’s work on cancer a “mission” and said Tannenbaum is “absolutely determined to use his remarkable skills as a mathematician and as a scientist” to defeat it.

Tannenbaum, who recently took his grandchild to a Mets win at CitiField, said coming to Stony Brook in 2013 was a homecoming, bringing him closer to his native Queens. He cited two famous graduates from Far Rockaway High School: the physicist Richard Feynman, who helped develop the atomic bomb, and Bernie Madoff.

He and his wife Rina, who is a professor in materials science and engineering at Stony Brook, live in Long Island City.

Tannenbaum hopes to continue to build on his work applying math to solving cancer.

“There’s a lot of mathematical play left and then testing the predictions in a biological/medical setting,” he said.

The two chimpanzees housed at Stony Brook University will not be granted the personhood necessary to allow them to challenge their captivity, a state Supreme Court judge ruled in an animal rights advocacy group’s lawsuit against the school.

Justice Barbara Jaffe ruled in her July 30 decision that Hercules and Leo, the two male chimps used for research at Stony Brook University’s Department of Anatomical Sciences, would not be granted a “writ of habeas corpus,” as petitioned for in the Nonhuman Rights Project’s suit against the university. The animal rights group had petitioned the judge with hopes of forcing the university to move the chimps to the Florida-based Save the Chimps animal sanctuary.

“The similarities between chimpanzees and humans inspire the empathy felt for a beloved pet,” Jaffe said in her decision. “Efforts to extend legal rights to chimpanzees are thus understandable; someday they may even succeed. For now, however, given the precedent to which I am bound it is hereby ordered that the petition for a writ of habeas corpus is denied.”

Jaffe cited previous suits the Nonhuman Rights Project had headed up, including one referencing a chimpanzee named Tommy who was being held through Circle L Trailers in Gloversville, NY. In that case, the Fulton County Supreme Court dismissed the Nonhuman Rights Project’s appeal to have the chimp released.

Steven Wise, president of the Nonhuman Rights Project, said his group was still looking forward to appealing Jaffe’s decision to the state Supreme Court’s Appellate Division’s first judicial department.

“Unlike Justice Jaffe, [the first judicial department] is not bound by the decision of the Third Department in Tommy’s case,” Wise said in a statement.

Despite the judge’s ruling, Susan Larson, an anatomical sciences professor at SBU, previously said both Hercules and Leo will retire from the facility’s research center and be gone by September. Larson did not return requests for comment.

The Nonhuman Rights Project, however, said it would work to ensure the chimps are released to a sanctuary nevertheless.

“We applaud Stony Brook for finally doing the right thing,” Lauren Choplin of the Nonhuman Rights Project wrote on the group’s website. “We have made it clear that we remain willing to assist Stony Brook in sending Hercules and Leo to Save the Chimps in Ft. Pierce, Florida, where we have arranged for them to be transferred, or to have an appropriate member sanctuary of the North American Primate Sanctuary Alliance, as we did in Tommy’s case. We have made it equally clear that, if Stony Brook attempts to move Hercules and Leo to any other place, we will immediately seek a preliminary injunction to prevent this move pending the outcome of all appeals, as we succeeded in doing in Tommy’s case last year.”

New Iberia Research Center in Louisiana owns the chimps, and their next destination was not clear.

The court first ordered the school to show cause and writ of habeas corpus — a command to produce the captive person and justify their detention — but struck out the latter on April 21, one day after releasing the initial order, making it a more administrative move simply prompting the university to defend why it detains the animals.

In an earlier press release from 2013, the Nonhuman Rights Project said the chimpanzee plaintiffs are “self-aware” and “autonomous” and therefore should have the same rights as humans. Hercules and Leo are currently being used in a locomotion research experiment in SBU’s Department of Anatomical Sciences.

Cliff Swezey joins Huntington school district, along with others

Huntington schools will see plenty of new faces this September, and not all of them will belong to students.

The school board approved a number of teaching appointments on Monday as well as the hiring of Cliff Swezey, the district’s new chairman of mathematics and sciences for grades 7 through 12. Swezey is the latest addition to fleet of new administrators at the district, particularly the high school level — joining Huntington High School Principal Brenden Cusack and two new assistant principals Joseph DeTroia and Gamal Smith.

School district officials reviewed 66 applications, pre-screened 20 candidates and conducted 12 personal and extensive interviews prior to recommending Swezey, according to a statement from the school.

Swezey, who hails from the Uniondale school district and served there as director of math and computer science for grades K to 12 for the last two years, said he’s excited to join Huntington. He said he developed a four-year computer science sequence for high school students in Uniondale, and would be excited to tackle a similar initiative in Huntington – something school board member Bill Dwyer has said he’d like done at the district.

Swezey replaces the district’s former chairman Blaine Weisman. He said he is an advocate of Singapore math learning techniques — the country boasts high math success rates — and the new chairman said the Common Core Learning Standards math curriculum utilizes those learning techniques. He also said one of his responsibilities at Huntington would be to help parents understand Common Core math.

“The Common Core is really an adaptation, an adoption, of Singapore mathematics,” he said. “So I’m passionate about that because it’s about thinking. It’s not about rote memorization. It’s not about learning procedures and rules in math, which turns kids off. It’s about critical thinking. It’s about problem solving. It’s about alternative strategies and getting kids to build numeracy.”

Swezey earned a bachelor’s degree in biology at SUNY New Paltz in 1984 and a master’s degree in education in mathematics at St. John’s University in 1995. He earned a doctor of education in educational leadership at St. John’s in 2004.

Superintendent Jim Polansky said the district’s still looking to fill a handful of positions. Many of the new hires follow retirements from earlier this year. Polansky said he’s excited about the new team at the high school.

“I have a principal in place that has vision that connects with students like no other and I think we have a team of individuals that are ready to build on momentum that is building at the high school in a positive way for a long time.”

Kids buddy up at kidOYO camp to learn more about the coding world at a special summer camp workshop hosted at Stony Brook University on Friday afternoon. Photo by Rachel Siford

By Rachel Siford

Stony Brook University is hosting a different type of camp this summer.

kidOYO teaches kids between ages 8 and 15 how to code their own websites and games, using Java, Scratch, Python and HTML.

“Code. Make. Learn.” is kidOYO’s motto — geared to teach kids to code and create on their own.

“The kids learn how to map controls, sense the movements and think about it in a logical way,” co-founder Devon Loffreto said.

Loffreto, a graduate of SBU, and his wife Melora Loffreto founded the camp in 2001 and came to Stony Brook University three years ago because of its position as one of the top computer science schools.

“This area has a huge interest in computer science,” Melora said. “The support of the university has been tremendous.”

Some kids stay just one week, and others participate for the full five weeks. This week, 33 students entered the program along with 10 Stony Brook University computer science student mentors to help them.

Chairman of the Computer Science Department for 17 years Arie Kaufman welcomed the crowd to the newly built computer science building. This group was the first to have a demonstration there.

“I want to move Long Island to the point where everyone from ages 4 to 104 knows how to program,” Kaufman said. “This is a happy occasion for the new computer science building.”

For the first time since the camp was started, participants will be able to continue their websites and work at home. Their profiles will keep track of what they do with badges they get for different accomplishments. There are also challenges and tutorials on the website to keep them engaged.

Students made mods for Minecraft, a popular video game, meaning they wrote code modifications for the educational version of the game Minecraft. One student even made the mod downloadable so anyone can add his mod to his or her own game.

“This generation is one of the most powerful ever because of the tools they are given,” Loffreto said.

Another student built a script in Python, a general-purpose programming language, to draw a turtle, which took 370 lines of code.

Students made videos, comic strips, games, 3D printed objects and video games. For many of them, this was their first time using code.

He has been to the Super Bowl, the Boston Marathon, a presidential inauguration, the Baltimore Grand Prix, the Rockefeller Tree Lighting and the ball drop in Times Square on New Year’s Eve. Lee Michel is neither a politician nor an athlete: He is part of a national, first-response team, called the Radiological Assistant Program.

The program is a unit of the Department of Energy, which assists local, state and federal agencies to characterize the environment, assess the impact to the local population and support decision makers on steps to minimize the hazards of a radiological incident.

Michel is the training and outreach coordinator in Region 1 of the program. He works with partner agencies around the country to deal with everything from the discovery of radiological material that someone might have accidentally brought home from a work site to an intentional detonation of a dirty bomb.

His job is a “full soup-to-nuts response to radiological material that shouldn’t be wherever it is,” Michel said.

He trains people at facilities around the country to understand “how to detect [radiation], how to contain it, how to identify it and how to mitigate it,” Michel said.

Kathleen McIntyre, the contractor operations manager for RAP Region 1, said her group is the first on-scene emergency response team representing the Department of Energy. One of nine programs around the country, the BNL team is responsible for a region that stretches from Maine to Maryland and to the Pennsylvania-Ohio border.

In addition to sports events and conventions, the team also assists with other high-profile events. In late September, the BNL RAP team will work with other agencies during Pope Francis’s visit to the United States.

In his job, Michel often travels to ensure he’s appropriately trained so he can teach other first-responder agencies. In the last several months, he’s been to Chicago, Albuquerque, Las Vegas, Boston, Connecticut and New Jersey.

These trips are necessary to create effective collaborations with local partners, said McIntyre. “Part of the thing that [Michel] does and does well is coordinate with our first-responder partners,” McIntyre said. The training and outreach ensure “if we are ever in a situation where we need to work together, this isn’t the first time we’ve met each other.”

While the mission hasn’t changed for the five years Michel has been in his role, the mechanisms have evolved.

“The equipment we’re using is much more sophisticated than what we had,” Michel said. “The software that runs the system or is used in conjunction with the system is much more advanced.”

Indeed, McIntyre said Michel regularly has to remain updated on the latest software and equipment, in the same way an owner of a laptop has to remain current on electronic updates.

Michel “has to be conversant with all these” systems, she said. “He has to hit the ground running. We don’t own every piece of radiological equipment out there. He needs to understand whatever he’s going to teach.”

McIntyre gives Michel “great kudos” for “rolling up his sleeves” as he tries to stay abreast of the changing technology.

In addition to training, Michel does exercises and drills with response teams, keeping the groups prepared to react to a wide range of potential radiological problems or events.

While the Radiological Assistance Program only has three full-time employees at BNL, the facility includes 26 volunteers.

Michel has been dealing with radiation for over 30 years, starting with eight years in the navy from 1981 to 1989 when he was a nuclear power operator.

Born and raised on Long Island, Michel is the third generation in his family to work at the Upton facility. His grandfather, Isadore Rosen, was stationed at Camp Upton during World War I. His uncle, Morton Rosen, took pictures for BNL for over 35 years. Michel, who lives in Holtsville, has two daughters, 26-year old Heather and 22-year old Michelle.

As for a fourth generation at BNL, Michel holds out some hope. “I would love to have one of them work here,” he said. He’s even entertained the idea of his seven-month old granddaughter Jemma one day contributing to BNL.

While the work involves traveling to high-profile events, it’s sometimes tough to soak in the atmosphere.

The 2009 inauguration involved working 14-hour shifts in single digits, McIntyre said. After their work, they come back for more assignments. These contractors and volunteers “who serve on the RAP teams are dedicated professionals.”

I recently had the pleasure of reading Lee Standlin’s “Storm Kings,” a short work on the history of weather forecasting and how scientists tried to figure out how storms form. The book begins with Benjamin Franklin’s discovery that lightning is electricity. I learned that Franklin was quite a showman as he toured Europe and the Colonies, showing his experiments with electricity.

I knew that much earlier people tried to interpret weather as the acts of gods. For the Norse, Thor was the god of thunder. For the Greeks, Aeolus was the deity who blew gale winds and caused ships to crash and sink under gigantic waves. For the Bible, Genesis describes the “waters above” and the “waters below,” distinguishing oceans from drenching rains as two separate creations of water.

In “Storm Kings,” we follow the bitter controversies of nineteenth century scientists who attempt to explain storm formation. Each participant is hostile to the ideas of rivals and theories collide with the ferocity of storms. But out of those debates, the Army Signal Corps was formed and established first, a series of flags to indicate weather for ships at sea and then, telegraph accounts of weather readings — temperature, barometric pressure, clouds, wind speed and direction — sent to military bases around the United States.

Politics played a role in the rivalry of contending candidates for heading up the Signal Corps and politics limited what it could forecast. Tornadoes were taboo because acknowledging them or determining their frequency would lower land values in the Midwest. The Signal Corps was cut back, had its operations shifted to the Agriculture Department and was renamed the Weather Bureau so it could be more effectively monitored by lobbyists.

After the Civil War, science began to change. Weather was seen as a complex physical process and weather fronts were identified. The collision of warm moist air from the south and cold dry air from the north led to line storms and tornadoes in the Midwest. It was not until World War II that a more thorough weather forecasting was allowed for the Weather Bureau.

What distinguishes the history of weather forecasting as a science from evolution in biology as a science is the relative absence of religious objections to the interpretation of storms and weather phenomena.

Disasters are still thought by some as visitations from God to punish the wicked. But no one would ban the teaching of the physics of storm formation or cloud formation in classrooms.

Astronomy and physics are also downgraded by some religious writers who deny the idea that objects can be more than 10 thousand light years away or that some elements in the earth have a radioactive decay rate measured in millions of years.

The brunt of the attack on science, however, is evolutionary biology, because it deals with life, and we humans are alive and aware of that existence. Most people have no clue what is meant by light years, radioactive half-lives of isotopes of elements, or the dynamics of ocean currents, wind patterns, and rising or descending masses of air. Unfortunately, almost all major religions have their origins hundreds or thousands of years ago when science was relatively new or altogether absent and the religious texts of those times reflect this.

By Daniel Dunaief

Mothers of more than one child have blogged about it for years. When they have their second child, the breastfeeding process is often quicker, with milk available sooner than for the first child. Camila dos Santos, who became an assistant professor at Cold Spring Harbor Laboratory in February, has found a reason.

Cells in the mammary gland go through something called epigenetic changes. That means something affects the genetic machinery, causing them to react differently under the same circumstances. In mouse models, dos Santos discovered changes in cell proliferation and milk production genes to the hormones estrogen and progesterone.

When she was a postdoctoral student in Greg Hannon’s laboratory at CSHL, dos Santos said they “decided to profile the epigenome before and after pregnancy.” At first, she was looking for changes associated with the effects of pregnancy on breast cancer development. The recent work, however, described the presence of epigenetic memory of past pregnancies, which influences milk production in the next pregnancy.

The message from these studies was that those areas where she saw changes “are associated with the genes responsible for lactation and the proliferation of the mammary gland during pregnancy,” said dos Santos.

The implications of this research extend from the potential to enhance breastfeeding in women who struggle during lactation to breast cancer.

Indeed, other studies have shown that women who become pregnant before 25 have a lower risk for all types of breast cancer.

“We believe that such strong protective effect must have an epigenetic basis,” dos Santos said. She would like to “understand how this stable, pregnancy-induced epigenome prevents cancer development,” she continued.

Hannon believes the kind of research dos Santos is conducting holds promise.

“The world of breast cancer prevention is badly in need of very solid underlying molecular biology and I think there’s a fair chance that what [dos Santos] is doing will eventually get us there,” said Hannon, who recently left Cold Spring Harbor Laboratory and is now the Royal Society Wolfson Research Professor at the Cancer Research UK Cambridge Institute at the University of Cambridge.

Dos Santos said her research is exploring ways to turn the changes that occur during pregnancies before the age of 25 into a “preventive strategy to treat women that are high risk and even those that are not.”

To be sure, Hannon and dos Santos cautioned, it’s difficult to know how quickly or even whether this kind of research will lead to any treatment or prevention options.

“The main goal of my lab is to try to understand the effects of pregnancy on normal cells, to devise a strategy to prevent breast cancer from arising,” dos Santos said. She recently published her work in the journal Cell Reports.

Dos Santos and Andrew Smith, a computational biologist from the University of Southern California, along with his postdoctoral fellow Egor Dolzhenko discovered that mice that had been through a single pregnancy had methylation marks that were different from mice of the same age that hadn’t been pregnant. The group connected the changes in the genome to a transcription factor called Stat5a. A transcription factor is a protein that acts like a genetic traffic light, turning on or off genes.

When she joined Hannon’s lab in 2008, dos Santos wanted to study gene regulation throughout cell development. It took her three years to purify stem cells.

Hannon credits dos Santos for developing new techniques.

“She had to build the tools she needed to ask” these questions, Hannon said.

Dos Santos lives in campus housing with her husband, Christopher Vakoc, who is an assistant professor at CSHL. The couple take their young sons hiking and can’t wait for the spring and summer because they hike, swim and kayak. Vakoc and dos Santos met when they were in adjoining labs in Philadelphia.

“We used to have joint lab meetings and one day he asked me on a date,” she recalled.

This summer, dos Santos’ lab will include a premed undergraduate student from Hofstra and high school students from Cold Spring Harbor High School and  Southampton High School. She recently hired a postdoctoral fellow.

“I envision my lab growing according to my needs,” she said. “Right now, I want to continue to work at the bench while training students and postdocs.”
