The Future of Medical Education: Death-Defying Robots

by Claire Watry, Terra Linda HS

This week the Marin Science Seminar introduces a unique presentation on medical education with Rich Fidler PhD MBA and Abi FitzGerald MSN RN of the VA Medical Center and their special guests – robots! These humanlike robots are utilized by medical practitioners at the Simulation Center at the VMCA in San Francisco to learn how to perform a variety of procedures and respond appropriately to different emergency scenarios.

Rich Fidler is the Director of the Healthcare Simulation which places him in charge of all of the simulation research, education, training, and process evaluations that take place in the entire hospital, including emergency, critical care, surgery, and disaster preparedness. Fidler is also the Co-Director of the Fellowship Program in Advanced Clinical Simulation. Fidler explains this role in the following quote; “I am responsible for ensuring that our advanced fellows are receiving challenging experiences, quality didactic education in statistics, research design, thoughtful data analysis. I also ensure that they will be able to go out to conduct clinical simulations independently.” In order to obtain these job titles, Fidler has collected numerous degrees and gone through extensive medical training.

Read the interview with Rich Fidler below and be sure to attend this weeks’s Marin Science Seminar.

What degrees and training do you have, and how do they relate to each other?

PhD in Physiological Nursing from UCSF–allows me to apply knowledge and principles of physiology to understanding biomedical engineering solutions to clinical problems.

MS in Human Factors Engineering–allows me to understand human-technology interfacing, and allows me to more completely understand the reasons that people have problems operating medical equipment.

Anesthesia Training–allows me the skill set for airway and physiologic patient monitoring and surgical perspective for a well-rounded clinical practice

Critical Care Training–allows me the experience to provide care for the sickest of hospitalized patients, applying physiology, chemistry, and pharmacology to improving patient conditions.

Primary Care Training–allows me the perspective to understand how diseases evolve over long periods of time, and also allows me to see how patients choose to participate in their healthcare

MBA–having a master’s of business administration allows me the knowledge to understand people operating in a system, particularly with skills related to managing people. Frequently, it is important for me to elicit a particular behavior from our staff, but this needs to be done respectfully so that the employees WANT to do a good job.

How did you become interested in the medical field?

I developed a special interest in healthcare when my grandfather became ill with heart problems while I was young. As early as 8 years old, I would go to spend every evening with my grandfather to try to make him feel better by pushing the fluid out of his legs. From there, I got more interested in why his heart was failing and how I could make it better. I got more interested in cardiac resuscitation after my grandfather had a sudden cardiac death event and we saved him. Then my own father had a series of 3 cardiac arrests which he survived from high quality CPR and early defibrillation, but he eventually died with the fourth cardiac arrest.

How did you become involved in the Simulation Center?

I have always liked teaching, and I think that learning with your hands is better than someone talking you to death. When I told my father about what I did with simulation, he said, ” You can’t make a living playing with dolls.” I guess I showed that you should do what you like to do, even if your parents don’t think it’s worthwhile. You have to make yourself, not your parents, happy with your career. The harder stunt is to figure out how to make lots of money doing what you love!

Example of a Simulation Center

What projects have you worked or are you currently working on in the Simulation Center?

Defibrillators.

Resuscitation.

Heart monitors.

Disaster evacuation from the hospital in the middle of surgery.

Should we unwire a jaw wired closed or do a cricothyrotomy to get oxygen to the patient?

What is the best way to open a chest for bleeding in the immediate post-open heart period?

What is the most rewarding part of your job?

Seeing people that did not know how to do something not only learn how to do it, but also gain a certain amount of confidence and mastery doing the new task.

What advice do you have for young people aspiring to have a career in the medical field?

Do it! My grandfather said that I should either be an obstetrician or an undertaker, that way you can get people either coming or going! If you aspire to go into the healthcare field, explore your options. Becoming a physician or nurse is not your only option to make a meaningful contribution to healthcare. Medical research, especially with the human genome, is really exciting. If I were growing up now, I would probably be fascinated with that. Also, the roles of pharmacists and therapists are frequently overlooked as vital members of the healthcare team. The money should NOT be a factor in your decision. No job is worth getting up every day if you hate going. I love going to my job every single day.

Check out this very exciting presentation “Death-Defying Robots in Medical Education” with Rich Fidler PhD MBA and Abi FitzGerald MSN RN of the VA Medical Center on Wednesday, May 14 7:30 – 8:30 pm, Terra Linda High School, San Rafael, Room 207.

Spreading Smiles Around the World

by Gillian Parker, Tamalpais HS

Dr. Maureen Valley

Maureen Valley is an orthodontic care provider at Valley Orthodontics in San Rafael, and she is Associate Professor and Director of the Postgraduate Orthodontic Clinic at the University of the Pacific School of Dentistry in San Francisco. You can read more about her career in orthodontics in the U.S. here.

She received her Doctorate in Dental Medicine (D.M.D.) and her Masters of Public Health from Harvard University, and her Bachelor of Arts degree in Biology at University of California, Santa Barbara. In the Summer of 2013, Dr. Valley traveled to Kenya with her husband to take part in a Rotary International project to improve oral health in Kenya. Click here for more information about the Kenya Smiles Project.

She primarily worked with a tribe called the Maasai. One member of the Maasai tribe, Mr. Samson Saigilu, a public health official in Kenya, worked alongside Dr. Valley on the Kenya Smiles Project, and he will be presenting with Dr. Valley at the upcoming Marin Science Seminar.

Samson Saigilu

Read the following interview with Maureen Valley to find out more about her work in Kenya.

Why did you decide to go to Kenya?

In 2012, I went to Kenya for the first time with my family for safari. I fell in love with the country and the Maasai people. I wanted to return, but this time to help the people.

What exactly were you your activities in Kenya?

The most important impact we made was education. We introduced the people to tooth brushing, as most all of them have never done this in their whole life. Also, education on nutrition as modern foods have now entered their communities. This in combination with no tooth brushing or dental care has been disastrous.

What are your favorite/least favorite parts of your job/working in Kenya?

My most favorite parts of working in Kenya: working with the beautiful Maasai people. My least favorite parts of working in Kenya: being labeled by the color of my skin. As it symbolized certain things. It was a strange experience for me.

What would you have to say to aspiring dentists and orthodontists?

Some advice for aspiring dentists and orthodontist: It is a great profession if you have the passion and willingness to help others, not only in your community, but also anywhere in the world. Here is a quote from Samson, “The passion for a community free from preventable diseases can always drive someone anywhere in the world.”

To learn more, go to the Marin Science Seminar, “Spreading Smiles Worldwide: Oral Healthcare Outreach and Research among the Maasai in Kenya” and hear Dr. Valley and Mr. Saigilu talk about their work in Kenya on Wednesday, April 23, 7:30-8:30 pm at Terra Linda High School, San Rafael, Room 207.

Public Health Challenges in Kenya

by Claire Watry, Terra Linda HS

As inhabitants of a developing nation, the people of Kenya face many obstacles in receiving basic healthcare. According to the Global Health Department at the Massachusetts Institute of Technology, there are five main issues in delivering adequate healthcare in Kenya: infrastructure, lack of funding, access to care in rural areas, price and affordability of medicines, and politics. Statistics from the World Health Organization in 2006 showed that the top five causes of death in Kenya were HIV/AIDS followed by respiratory infections, diarrheal disease, tuberculosis, and malaria. While healthcare in Kenya has been steadily improving, there are still many challenges to overcome especially concerning healthcare access in rural areas. The video below shows the hardships people in rural areas of Kenya face in obtaining healthcare.

Affordable Health Care Still a Dream for Rural Kenya

Access to clean water is one of the biggest health issues in Kenya, especially in rural areas. In rural areas only 54% of people used improved water sources compared to the 83% of people in urban areas who used improved water sources in the year 2011 (UNICEF). In rural areas, the water sources are often shared by livestock and contaminated by feces from the livestock, making the water unsafe to drink.

A short-term solution to unsafe drinking water is the LifeStraw water filter. The LifeStraw water filter allows an individual to drink directly from a water source or bottle just as a person would normally drink through a straw. The waterborne bacteria and other contaminants found in the water can cause severe diarrhea, which is the third leading cause of death in Kenya. LifeStraw prevents these deaths by effectively removing 99.99999% of bacteria and 99.9% of protozoa from the water.

Kenya is reliant on outside donors and organizations in order to receive adequate and affordable health services. The LifeStraw Carbon for Water campaign put on by ClimateCare is one of these many organizations. This project distributed 877,505 LifeStraw Family filters to households in Kenya’s Western Province which supply safe drinking water directly to 4.5 million people. The video here explains the project and its success in depth.

Another organization called BedNets for Children distributes bed nets to prevent children and their families from contracting malaria from mosquitos. A statistic from the organization’s website states that a child in Africa dies every 60 seconds from malaria. Bed nets have been shown to be very effective in preventing malaria especially for young children under two years of age. The World Health Organization has reported a 33% reduction in malaria deaths in sub-Saharan Africa since 2000.

The First Lady of Kenya Margaret Kenyatta recently announced a “Beyond Zero Campaign” to improve maternal and child health outcomes by combating HIV/AIDS. According to the website, “fifteen women die every day due to pregnancy related complications in Kenya and 20% of all deaths among mothers in the country are AIDS-related.” The campaign has five key elements: “(i) Accelerating HIV programs, (ii) Influencing investment in high impact activities to promote maternal and child health and HIV control, (iii) Mobilizing men as clients, partners and agents of change, (iv) Involving communities to address barriers to accessing HIV, maternal and child health services and (v) Providing leadership, accountability and recognition to accelerate the attainment of HIV, maternal and child health targets.” The goal of the project is to eliminate preventable deaths in children and mothers.

This week’s MSS speaker Maureen Valley DMD MPH participates in two organizations that teach the importance of oral hygiene in Kenya, Kenya Smiles and the Loitikotok Oral Health and Nutrition Project. Through these organizations, Valley distributes toothbrushes and toothpaste, collects research about dental hygiene, and educates children and other community members about oral health.

Do Fetuses Experience Pain?

by Gillian Parker, Tamalpais HS

Controversy over abortion laws has led to many other discussions surrounding the development of the fetus. When does a fetus begin to feel pain? When does it gain consciousness? What are its cognitive abilities in the womb? This essay will attempt to answer these questions.

It is still unclear when human babies/fetuses begin to feel pain. The first step to feeling pain is to develop the necessary neuroanatomy. Evidence suggests that the necessary anatomical developments are in place at as early as 26 weeks gestation. When a fetus of approximately 26 weeks is exposed to noxious stimuli, it will respond to them, although minimally (Derbyshire, 2006). There are studies which claim to record evidence of fetal expressions of pain and/or distress. In one particular study, 8 female and 7 male fetuses were scanned with a 4-D ultrasound four times during the second and third trimesters of pregnancy, or 24 to 36 weeks gestation. The study specifically focused on expressions of pain or distress. Researchers concluded that as the fetus matured, so too did its visible responses to stimuli. However, the fetuses were not provoked in any way, and these responses did not reflect the fetuses’ emotional or cognitive state (Reissland, 2013).

Although fetuses technically have the anatomy to experience pain around 26 weeks gestation, it is unclear whether or not they actually experience pain as we know it, because of their minimal level of consciousness. Pain is defined as “an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage” by the International Association for the Study of Pain. In spite of its anatomy, it is thought that fetuses do not experience true pain, because they are not conscious of it, and have no experience or memory to base their pain on. The fetus is actually provided natural sedatives from the placenta just as it receives nutrients from it. The fetus is asleep for the duration of gestation. It is suspended in a warm, cushioned environment and it does not know anything but this. It is unlikely that it would be able to experience true pain, as it is unconscious and has no basis for comparison. Essentially, the fetus has not yet learned how to experience pain, or identify itself as an individual (Koch, 2009).
In conclusion, it is unclear exactly when the fetus reaches a conscious perception of pain. Though the fetus develops the anatomy to respond to pain during the latter part of pregnancy, and can even make facial expressions of pain and/or distress, there is no correlation with the fetus’s actual comfort level. The placental sedation of the fetus means that it has no memory or “experiences” and therefore is unable to experience pain in the conscious way that adults and children understand. Further research may someday uncover more information on this complex and controversial question.

The Adorable, Rewarding, and Sometimes Difficult Task of Birthing Babies

by Claire Watry, Terra Linda HS

A common misconception is that the only job of a midwife is to deliver babies. In reality, the duties of a midwife begin long before the baby is born. A midwife can screen for diseases, prescribe certain

medications, help the mother stay healthy during pregnancy, monitor the baby’s growth before and after

birth, provide emotional support, discuss care options and breastfeeding, support the mother and

her child after birth, and provide many more services in addition to the delivering the baby. As a

midwife, upcoming MSS speaker Sheri Matteo is responsible for the health and wellbeing of a woman

and her baby for the entire length of the pregnancy and beyond. The video below shows the benefits of

midwifery for women.

Midwifery Care: What’s in it for women?

Matteo explained that midwifery in the U.S. has undergone many changes throughout history.
“Before the early 20th century, most babies in the US were delivered by midwives at home. Then
medicine, mostly male doctors, brought birth into hospitals and birth became a medical condition.
Women were put to sleep and babies were delivered with forceps. Moms were encouraged to bottle
feed. Midwifery pretty much vanished. In the 1970’s, with the rise of feminism and the “natural birth”
movement, midwifery as a profession started to grow again. Unlike many other industrialized countries
with better childbirth statistics where midwifery care is the norm, midwifery in the US has stayed on
the fringe and been seen as an “alternative” birth option. In the 15 years that I have been practicing,
I have seen many midwifery services grow and disband based on whatever economic issue was driving
healthcare at that time. Healthcare in the US is still largely driven by economics and legislation, but
midwives and other “mid levels” or “allied health professionals” are rising in use and stature. We
have rigorous education and certification maintenance programs and are fully integrated into healthcare
teams with nursing, case managers and social workers, as well as doctors. The profession is growing in
numbers and strength and our good outcomes are more commonly recognized by clients and medicine
professionals.” According to Time magazine, approximately 8% of babies born in the U.S. – a record
high – and about 24% of babies in New Mexico were delivered by midwives in 2009. While delivery in
the U.S. usually takes place in a hospital in the presence of obstetricians, more and more women are
turning to midwives.

Read the rest of the interview with Sheri Matteo for a sneak peek preview of her upcoming MSS
presentation “Birthing Babies: What it Takes to be a Nurse Midwife”.

How did you decide to become a midwife?

I was premed in college and always thought I wanted to be an obstetrician. I was also a singer and performed in HS and college plays. I spent my junior year abroad studying acting in London and when I returned I realized I no longer wanted to go to med school. I received my BA in Theatre Arts at Brown University. I worked as an actress in NYC, off-Broadway and as a member of a theatre company. Working on a play with an older actress, I discovered her daughter was a midwife. I didn’t even know midwifery was a profession at that time! Shortly after, I met a woman who was an obstetrician. I was really inspired hearing about her work. She invited me to “take call” with her one night at the hospital. I saw a birth and I was hooked! Midwifery appealed to me more than medicine because of its emphasis on childbirth as a natural part of life, not a medical condition that needs to be “treated”.

How does one become a midwife? What sort of training or education is necessary?

There are many different kinds of midwives in the US and several different ways to become one. There are “lay” midwives who receive traditional training as an apprentice of another lay midwife. These midwives are sometimes state licensed and sometimes not. They are not eligible to work in hospitals so they only do home birth. To be a Certified Nurse Midwife, I had to enroll in nursing school with the plan to continue onto graduate school. I went to Columbia University School of Nursing in NYC. They have a special nursing program for people who already have a baccalaureate. Instead of four years, I earned my BSN (Bachelors of Science in Nursing) in one and a half years. I continued on to complete my Masters in Nursing (MSN) in another one and a half years, for a total of three straight years and two degrees.

What are the responsibilities of a midwife? What is a typical day?

Certified Nurse Midwives can perform nearly all aspects of women’s health primary care. We screen for diseases, including cervical cancer, breast cancer and STDs. We can prescribe medicine including birth control and antibiotics. We perform prenatal care, making sure moms stay healthy in pregnancy and their babies are growing well. We can deliver babies in the hospital, in birth centers, or at home. We support women with breastfeeding and take care of them postpartum. We do a lot of client teaching about their health, bodies, and care and treatment options. Though we do not perform surgery like c/sections, we are hands-on surgical assistants. A typical day involves either working at the clinic seeing prenatal patients (between 12-20 in 8 hours) or working in the hospital supporting moms in labor and delivering babies. Because I am the Director of my group of 12 midwives, I also have office work and a lot of meetings to attend. I work on marketing my group’s services, hospital quality and safety and employee satisfaction and performance.

What is the most exciting, rewarding, or difficult aspect of being a midwife?

Watching new families grow! Helping women be and stay healthy. Meeting all kinds of people from all different cultures. Working with women and empowering them to believe in their natural ability to birth and mother.

What advice do you have for young people aspiring to be in a healthcare profession?

It is very hard work but also very rewarding. Never forget to treat all people with dignity and respect.

A Renewed Sense of Porpoise – An Interview with Jonathan Stern

by Claire Watry, Terra Linda HS

Harbor porpoises have returned to the San Francisco Bay after a 65-year absence. What does their return mean for the other animals of the bay? Why did they leave? Why might they have returned? This week’s Marin Science Seminar speaker Jonathan Stern will address these questions and provide insight into the world of local harbor porpoises. The video below is a tribute to the harbor porpoise’s return to the bay by the National Wildlife Federation California.

Fast Fasts about the Harbor Porpoise from the National Geographic Society:

Terra Linda High School graduate Jonathan Stern is a lecturer and adjunct professor in the Biology Department at San Francisco State University. He has studied minke whales since 1980 and currently serves as a Co-Principal Investigator at Golden Gate Cetacean Research, where he studies harbor porpoises, bottlenose dolphins, and minke whales locally in the San Francisco Bay. He has also studied an assortment of whales including gray whales, killerwhales, fin whales, humpback whales, and pilot whales. He was the first volunteer at the Marine Mammal Center when it opened in 1975.

How did you decide to study marine life?

My father was a ship captain, who traveled all over the world. When he would come home, he would bring me seashells from the places he traveled. I also watched Sea Hunt and Jacques Cousteau when I was a child and was fascinated by the sea.

From left: Lloyd Bridges stars in Sea Hunt, Seashell collection, Explorer Jacque Cousteau

How do you conduct your research?

This varies depending on what specifically I am studying. I do my observations from the shore and a boat. I also spend a considerable amount of time doing data analysis. I sit with my computer and books about statistical analysis and modeling.

Harbor Porpoise sighting near the Golden Gate Bridge

What is the most difficult aspect of your work?

My works is not difficult; it is challenging physically (being out on the water in a small boat on the open ocean takes its toll over the years) and the data analysis and the writing of papers take time to get things right. The challenge is fun!

What is one of the most surprising or exciting thing you have discovered about porpoises?

We have seen porpoises mating. This sounds like it is not a big deal, but given that these porpoises are among the most commonly seen marine mammal, we are the first to see them mating. The real surprise though is that we can do most of our observations from the Golden Gate Bridge.

What advice do you have for aspiring young scientists?

Prepare yourself! Prepare yourself by taking as many math and science classes as possible. Prepare yourself by learning to keep your focus, but keep your eye on other branches of science. Prepare yourself by learning to ask questions. that is the most important part of science, asking questions. Do not be afraid of the challenge. Prepare to study, work, and have fun. Science is a process.

The Fascination Behind Ants

by Claire Watry, Terra Linda HS

Did you know that ants are capable of carrying 50 times their body weight in their mouth? Or that ants are the original farmers? Or even that the total biomass of all of the ants on the planet is roughly equivalent to the biomass of all of the people on Earth? These are three of the many reasons why ants are so fascinating. The small insect that most of us view a pest is actually a intriguing specimen and worth the time and effort to research.

Marin Science Seminar returns in 2014 with a presentation titled “Ants: The Invisible Majority” with Dr. Brian Fisher. Dr. Fisher is a modern day explorer who journeys through remote tropic areas in search of ants. His research utilizes ants as a tool to discover and preserve plant and animal diversity in these places. Dr. Fisher has discovered over 1000 new species of ants including the jumping ants and Dracula ants. He has appeared in a number of BBC, Discover Channel, and National Geographic films and has been profiled in Newsweek and Discover magazine. When he is not working in the field with ants, Dr. Fisher lives in a tree house with the banana slugs. He is currently Chairman of Entomology at the California Academy of Sciences and adjunct professor of biology at UC Berkeley and San Francisco State University. In the video below, Dr. Fisher details why he believes ants are so cool.

The following interview shows his experiences with ants and his passion for his research.

How did you decide to become entomologist?

I actually thought I was going to be a botanist, but after a trip to Panama as a sophomore at the University of Iowa, I was struck by the ants’ diversity, abundance, and ecological role. Its not just their diversity that is fascinating. After all beetles are diverse – there are 40,000 leaf beetles – but they all just eat leaves. Ants, on the other hand, have evolved the most diverse and surprising ways of making a living from growing fungus to tending to aphids. Also, because ants are social, there is a whole other dimension that is fascinating that is not even possible with solitary insects. After working on plants a bit that year in Panama and I dropped the “pl” and just worked on “ants”.

Why did you choose to study ants specifically?

I remember I changed the day I discovered an orchid in the canopy in Panama. This orchid had a specialized home for ants to live and produced nectar for the ants to eat. This was the first orchid to have such a relationship with ants. After researching the ants on this orchid, and learning how their trash pile in the orchid bulb helped feed the orchid, I was hooked on ants.

Where has your research taken you?

I have worked mostly in the tropics, especially South America, Africa, and Madagascar. Ants are much more diverse in the tropics. Antarctica, the only continent named after ants, actually doesn’t have any ants.

Dr. Fisher collecting ants in Madagascar.

What is the most difficult aspect of your work?

To be a field-based explorer and a scientist requires you to juggle a lot – from fund raising and government permits to extreme field conditions to sitting endlessly looking through a microscope.

What is one of the most surprising or exciting thing you have discovered about ants?

In Madagascar, I have discovered over 800 new species of ants, including Dracula ants. These “primitive” ants feed off the blood of their own larvae. Why are we so interested in discovering life on Mars when right here on Earth, we know so little. We are also probably the last generation that will have a chance to explore much of this diversity before it goes extinct.

Dr. Fisher’s Ant Collection

What information can people learn from ants?

Ants are social and, like humans, face many of the same problems such as communication, group problem solving, food transfer etc. By studying ants, we are learning how ants, after 150 million years of evolution, have solved these shared problems. Some of these studies on group intelligence and neural networks are already making an impact in the field of artificial intelligence.

How do people react when you tell them about your work?

After I give a lecture, where I detail the wonder of the secret lives of ants, the first question I get is always, “How can I kill the ants in my kitchen?” My response? I tell them to leave some cookie crumbs on the counter and watch the ants. It is a rare treat to watch these wonders right in your own home.

Still not convinced that ants are fascinating? For countless reasons why, come to the Marin Science Seminar presentation “Ants: The Invisible Majority” with Dr. Brian Fisher Ph.D. of the California Academy of Sciences, January 22, 2014, 7:30 – 8:30 pm, Terra Linda High School, San Rafael, Room 207

Rethinking Buildings with Cyane Dandridge

by Claire Watry, Terra Linda HS

When I was asked by upcoming MSS speaker Cyane Dandridge, executive director and founder of Strategic Energy Innovations and executive director of the Marin School of Environmental Leadership, what the 5 “R”s are, I easily breezed through the first 3 – reduce, reuse, recycle – and managed to recall the fourth one – rot – but I could not think of the mysterious fifth “R”. Rethink is the fifth “R” and a very important one at that. As a community and as a society we must rethink how we use energy. For Cyane Dandridge and Strategic Energy Innovations, it begins with rethinking all aspects of buildings. People don’t normally think of buildings as the gateway to a more environmentally-friendly and energy-conscious society, but Dandridge maintains that they should be at the forefront. The various components of buildings – space for the building, resources for construction the building, electricity to power the building, even the stuff in the building – can be carefully considered, scrutinized, and altered to be more green.

Statistics from the EPA

Dandridge got an early start in the energy-efficient building movement. While attending a boarding school, Dandridge built a small house for two people using passive solar to capture heat. She then went to study physics at Reed College in Oregon. She served as a consultant to help people get solar installed. Dandridge then went on to MIT to study in the new building energy efficiency program. After her time at MIT, Dandridge worked for the EPA designing the energy star programs before founding Strategic Energy Innovations.

Dandridge founded Strategic Energy Innovations (SEI) in 1997 to answer the question of how can we help communities engage in sustainable practices. SEI is based on four pillars – jobs, government, housing, and education – and a collaboration of the four pillars to achieve sustainability within communities. See the video below to see more of what SEI does.

The project-based boarding school that Dandridge attended served as inspiration for the Marin School of Environmental Leadership. The goal of the program is to create strong leaders and use the environment to address critical issues. The students in the program learn imperative 21^stcentury skills – how to be engaged, how to take initiative, how to communicate effectively, how to think critically, and how to be innovative through project-based learning. The goal is to expand the program and spread the model to other schools.

A Behind the Scenes Look into the Lawrence Berkeley Lab with Polite Stewart

by Jessica Gerwin, Drake HS

What makes Polite (pronounced “po-leet”) Stewart stand out from any other person working in the Advanced Light Source department at the Lawrence Berkeley Lab? The answer is that Polite is only nineteen years old. His remarkable story begins with a young boy who has a knack for learning.

Ever since an early age, Polite’s parents could tell that he picked up new concepts at a much faster rate than other kids. After being enrolled in the Baton Rouge University at fourteen years old, Polite entered the Timbuktu program there which is designed to focus on studying advanced subjects of English and math. Polite excelled in his academic experience there and became one of the youngest graduates of the university’s 132 year history. His passion for physics can be expressed in his current work with the Advanced Light Source (ALS) at the Lawrence Berkeley Lab.

What is the Advanced Light Source? “Think of it as one of the world’s most powerful microscopes. With such a tool, scientists and industry can study materials at the molecular level, such as improving the physical structure of pharmaceutical drugs to increase effectiveness, studying the degradation of materials in batteries to build energy storage devices that last longer, and identifying how the molecular structure of solar cells impedes energy conversion efficiency.” [1]

In the interview below, Polite talks about his work at the lab and provides valuable insights on how to strive reach your highest potential level of success. His topic is highly specific so some here are some explanations of terms.

Terms:

Postbac – Post Baccalaureate (a college level degree)

ALS – The Advanced Light Source is a specialized particle accelerator that generates bright beams of x rays for scientific research. [2]

How the ALS works – Electron bunches traveling nearly the speed of light, when forced into a circular path by magnets, emit bright ultraviolet and x-ray light that is directed down beam lines or tubes to different research labs. [2]

How Bright Is It? – The ALS produces light that is one billion times brighter than the sun. This tool offers research in materials science, biology, chemistry, physics, and the environmental sciences.

Interview:

1. What first sparked your interest in physics?

My interest in physics is related to kinetics (motion) Newtonian physics, and that interest was piqued because I knew it would be useful to know about force transmission in the martial arts. It also helped me gain a better understanding of mathematics, engineering, and chemistry via research and self-study; everything is connected. My true interest is bio-engineering. I plan to research neuro-muscular theory to help people improve and repair lost neuron connection.

2. What specific topic are you studying?

At the moment, I work with hard X-Ray Scattering, specifically Small-Angle(SAXS) and Wide-Angle(WAXS). X-ray scattering is an analysis technique that uses x-rays to determine the structural formation of an object. At my beam line, 7.3.3, we specialize in protein, block co-polymer, polymer, and semi-conductor based samples. Transmission SAXS/WAXS is used to view a sample’s interior; whereas, Grazing Incidence(GISAXS/GIWAXS) is used to look at the surface structure of a sample.

3. You are working with very sophisticated machines and ideas. Can you explain to high schoolers what the synchrotron does?

A synchrotron is a huge particle accelerator that uses magnets to control electron bunches. The electron bunches are what make up the particle beam that each beam line end station (workplace) uses. The particle beam at our synchrotron is only a few micrometers wide and over 10x brighter than the sun.

4. Why is a synchrotron important?

Well, that has a very long answer. The simplest answer would be to state that the aforementioned electron bunches are necessary to irradiate samples and therefore extract data…but, let’s go deeper than that. First, a synchrotron is a just another version of the particle accelerator. So, we must determine why a particle accelerator is useful. Fundamentally, it is known that everything in this world is made up of atoms and molecules. There are smaller particles but we will only concern ourselves with the structures, for now, and not their components. Atoms and molecules are, of course, too small to see with the naked eye so, in essence, particle acceleration is our window into the world of the micro- and nano-structures.
How does this work? The electron bunches are sped up to a very high constant speed and then the bunches are sent down each individual beam line’s lead tunnel. The light is then rammed into your sample. When this occurs, the electrons in the beam will then collide with atomic and molecular structure of your sample. This will cause photons (light emission from the bouncing of electrons in particle space) to be emitted. This emission is then recorded and visualized as a scattering profile. This means that a synchrotron is very useful for allowing us to see the unseen. It is one of the many windows that helps us to understand the results of biology, chemistry, and engineering as a whole.

5. What do you hope to learn from this research?

This research has only one real goal. It is to speed up the progress of science. At the synchrotron, there is something called beamtime. Beamtime is the experiment time given to each scientist who writes a proposal to use our beam line. This implies that many research groups frequent our beam line and the synchrotron itself. My job, and my employers’, is to aid in the experimentation process. This increases (research) paper output, which in turn increases the output of scientific knowledge, and eventually improves consumer life (i.e. you).

6. Is this something that will help everyday people or businesses? Or both?

The research that we do at the Advanced Light Source (ALS) is designed to help the commercial (consumer) and financial (business) sectors because helping the commercial automatically helps the financial.

7. How long do your projects take?

I have two jobs as a student researcher on the beam line: help the users (various research groups) at the beam line and write programs/make changes to enhance, and increase the efficiency of, the beam line. User assistance only lasts as long as the given research group’s experiments. On the other hand, enhancement of the beam line will never stop.

8. What is a typical day in the lab like?

There is no such thing as a typical day, but I would say days normally start off with determining whether users are present. If they are, the whole day is generally devoted to helping them with experiment setup and execution. If there are no users, then the morning might be spent cleaning the beam line and the remaining afternoon would be devoted to programming.

9. Where do you see yourself going?

Currently, I see myself working for another year. Hopefully, it will be with Lawrence Berkeley Lab in the life sciences department. If not, I will apply to other labs and try to get a biological position. In the future, I would like to get a Masters in Bio-Engineering, possibly from Berkeley, and then go overseas to get my PH.D. and do my post-doc in Japan.

10. What do you recommend high school students do to get involved in research?

This is a difficult question. The first step is to cultivate and maintain a self-driving spirit and will. From a different take, I’m saying that, first and foremost, the level to which you want to learn determines how much you learn. Effort and excellence are proportional; even you don’t see the results immediately.
Now that effort has been determined as the essential element, let us discuss the limiting factor: resources. Resources (lab equipment and opportunities) are hard to acquire and difficult to locate. However, there is a hack…and then there’s a cheat code. I know they sound the same but they most certainly are not. The cheat code are summer programs. Look up as many as you can, find the ones that interest you, and apply with all the initiative you can possibly muster.
Finally, the hack is the ability to network. How do you develop this hack? Talk to anyone and everyone who gives off a positive light. In school, on the street, in the store, at home, and especially at a place you would love to work at in the future. The key to your success is your voice and your ability to use it. When you see a person who could benefit you, address him/her, introduce yourself, and begin to discuss how you could help them and they can help you. Only practice can make you adept at communication, but once you can talk with poise and demonstrate mental rigor…there will be no limiting you or the passion which you hold in your heart.

Imitating Nature Through Robotics

by Claire Watry, Terra Linda HS

What do Olympic swimwear, Velcro, and office buildings all have in common? They are all inspired by nature and created through the process of biomimicry. According to the Biomimicry Institute, biomimicry is “a new discipline that studies nature’s best ideas and then imitates these designs and processes to solve human problems”. The high-tech swimsuits worn by Olympic swimmers (before they were banned from competition) to be able to swim faster are based off of shark skin. Velcro is a hook-and-loop product created by Swiss engineer George de Mestral based on a burr. Termite dens serve as the inspiration for office buildings because of the ability of their cooling chimneys and tunnels to maintain a constant internal temperature.

Meet Terra Linda High School grad Ian Krase, a junior at University of California, Berkeley studying mechanical engineering who will be presenting at the upcoming Marin Science Seminar. In his presentation Bioinspiration: Bird-bots and Bug-bots at Berkeley, Ian will discuss how robots are developed through the process of biomimicry. In college, Ian joined the Fearing Lab, a group that works to create small, efficient robots by mimicking nature. Ian’s explanation of the Fearing Lab is “in university research, each professor runs a lab, with several graduate students who are working on their PhDs or Masters degrees. Each student has a project, and the whole lab has a unifying theme with its own laboratory space and shared resources. Fearing Lab is Professor Fearing’s lab, and is focused on biomimicry and small-scale robotics.” The interview below shows how Ian became interested in robotics, what kind of work is done in the Fearing Lab, and advice on how to become involved in robotics.

What sparked your interest in robots?

I’ve been interested in mechanical things for as long as I remember, and robots are a developing field with some of the most interesting open questions. While I tried building a robot in junior high on a whim, my current interest began when I saw some robotics labs while visiting colleges.

What past project are you most proud of?

Probably the work I did on BOLT (Bipedal Ornithopter for Locomotion Transitioning), a hybrid running and flying robot. I designed a carbon fiber frame for it to allow it to steer. My work on flight evolution was also pretty cool, but the part I actually worked on didn’t end up panning out very well.
