2Glendale Chocolate Affaire

Guest Author: Lisa Herrmann, science writer, Arizona SciTech

Nationally the confectionary industry spends over 2.3 billion dollars a year transporting and processing 1.9 billion pounds of cocoa beans from Central and South America to make the billions of chocolate treats exchanged throughout our US economy. We love our chocolate.  But scientists debate the root of that love.

The physics and chemistry of cocoa beans and cocoa products (also known as cacao, but not to be confused with coca!) are very complex. Thus, chocolate varies significantly based on the growth environment of its cocoa and the processing received. But all chocolate contains the alkaloids theobromine, phenethylamine and caffeine. These have physiological effects on the body, such as alertness. Theobromine is also a vasodilator and is linked to serotonin levels in the brain, which is associated with feelings of love.

Chocolatiers however, believe the love of chocolate comes from the care with which they transform basic cocoa products into candy. This process starts with blending, in varying amounts, the sugar, cocoa butter, cocoa liquor and any additional flavorings or milk products that result in variations such as dark chocolate, milk chocolate, or white chocolate.  The texture is also heavily influenced by the conching process which produces cocoa and sugar particles smaller than the tongue can detect, hence the smooth feel in the mouth. Tempering chocolate is a heat treatment method performed on chocolate involving heating and cooling the chocolate to result in shininess and the ‘snap’, or way it breaks. A chocolatier must know how to take chocolate through all of these processes to produce the characteristics that will induce our desire for the product.

So is it the the obromine’s effect on our brain, or it just the fact that it tastes to good? Conduct your own research at the 20th Annual Glendale Chocolate Affair, Friday, Jan. 30 and Saturday, Jan. 31. The Arizona SciTech Festival will be hosting its own area focused on the ‘Science of Chocolate,’ investigating all the complexities of our love affair with this marvelous substance. Event hours are Friday noon – 10 p.m. and Saturday 10 a.m.- 10 p.m. The event is located in the heart of Historic Downtown Glendale, in Murphy Park, located at 58th and Glendale avenues.

Guest Interviewer: Ann Marie Cunningham, for Arizona SciTech

Interviewee: Rick Heuman, vice mayor, Chandler, Arizona, which hosts Chandler Science Spectacular

How did you get involved in AZSciTechFest?

I went to Brooklyn Tech, long before Brooklyn became gentrified and hip.  The high school’s neighborhood was severely economically deprived.  I came out to Arizona in the 1970s to attend ASU.   I liked the West, and I liked the fresh air.

Chandler is in the East Valley, along with Tempe and Mesa.  There are now 1.7 million people in the East Valley.   When I took office, Chandler didn’t have a fiduciary school district.   I thought an education coalition between business and the schools would make sense, especially since we have two universities and community colleges in the East Valley.

The education coalition launched four years ago, right before AZSciTechFest.  Jeremy came to see us, and talked about how the Fest could be a tool for economic development as well.   Cities could showcase what they do best, and we want to teach kids to be problem-solvers.

Southwestern Arizona is known as “Silicon Desert,” and education is strongly tied to economic development here.   Our large high-tech industry can’t stay in our state if the labor force isn’t here.

So Chandler’s mission is two-fold.  First of all, we want people to understand STEM.  Secondly, we want them to understand that STEM is involved in every aspect of their lives, especially careers — even if they just work in an office on a computer.

What does the Chandler Science Spectacular involve?

We are a two-day event.  The last couple of years, Intel has been a sponsor.  We keep all events in a concentrated geographic area, so people don’t have to drive.  There is as much for kids as possible.  It’s all free.

The first year, on opening night, four or five local high-technology and microchip companies opened their doors to any and all visitors for the first time.  They had something like 11,000 employees, but on that night, what they did was open to all.  Everyone could see what they did, and how they did it.

On Friday, we hold an Art Walk, focusing on the science of art.   That’s the largest event we have right now.  There are sculptural welding and glass blowing demos – lots of technology involved.  In Chandler, we do have the Center for the Arts, which schools use during the day.

Tempe held a terrific event on the art and science of baseball.  I played for ASU’s baseball team and never had a free weekend, so that was very important to me.

Saturday is devoted to schools and business.  There’s a six-hour fair that involves 60 companies and all the local schools and colleges.  Everything is hands-on, from rockets to forensics.  Everyone loves hands-on.   We had the U.S. Army last year, and we want the Air Force this year, with all their resources.

Last year, we tied the Science Spectacular to the car show, which was held downtown. It’s important to utilize what you have; don’t reinvent the wheel.  On Saturday, we got 10,000 people. Usually the car show draws 1,000 to 5,000 people per day.

What’s the best way for a start-up science festival to emphasize STEM’s importance to economic development?

You’re a convenor, an aggregator of STEM content.  You need buy-in on the electoral side.  You need the school districts.  Find out what each city does best.  Then you go to the companies, and recruit them.

Meet with people who are already running festivals and farmers’ markets in the community.  Find out what STEM ingredients you can bring to what they’re doing.  They may be able to help you with marketing and budget.

Have one keystone event where everyone, all your partners, are doing something together – a fair, an expo, a science pavilion, something sparkly.

2SRP

Guest Author: Lisa Herrmann, science writer, Arizona SciTech

Formed originally in 1903, SRP was one of Arizona’s earliest STEM industry leaders, and since that time, it has continued to support citizen understandings of the water/power nexus so unique to our state. SRP has demonstrated a deep commitment to STEM education in Arizona through a breadth of corporate contributions over the years, such as with its Silver Level sponsorship of the Arizona SciTech Festival and multiple avenues of investment in the state’s teachers and classrooms. SRP utilizes its expertise and human resources through in-kind services and volunteer assistance and also funds scholarships, teacher grants, and a variety of educational support programs.

Kevin Rolfe, SRP’s Community Outreach Education Representative, recognizes the challenges of today’s classroom teacher, and explains that their program offerings are a way of supporting teachers and their critical work. SRP funds some aspects of teaching programs at the three state universities, but Rolfe’s main emphasis is providing trainings and resources for in-service K-12 teachers. ‘We offer 24-26 free workshops each year, generally for 4 hours on a Saturday. These teachers receive the training and hands-on materials they can take back and directly apply in the classrooms.’ With some workshop programs, SRP also includes mini-grants for purchasing additional materials. Not surprisingly, workshop topics include electricity and water education, but many also have a sustainability focus. ‘Our workshop on solar energy discusses the challenges with this energy source, but also the advancements’, Rolfe describes. Four day workshops for teachers offered during the summer have included topics of energy, land use impacts, and climate change.

Free teacher training, free teacher resources, including full classroom sets, and grants for classroom needs are all available by connecting with SRP online: www.srpnet.com/education.

Are you ready to jump into the game? In case you missed it, the 2015 Super Bowl will be played at the Roy picture1University of Phoenix stadium. The Arizona Science Center is hosting the most extensive exhibition ever built about America’s most popular sport, “Gridiron Glory: The Best of the Pro Football Hall of Fame.” This exhibit tells a remarkable story of the game – how it has evolved and how it has found a place in the conscience of the nation. This groundbreaking exhibition will be held daily, 10:00am-5:00pm, from January through May, 2015.

Roy picture2The Pro Football Hall of Fame, as part of its 50th Anniversary celebration, is currently touring the largest traveling football exhibition. Featuring NFL Films video footage and a series of interactive displays, Gridiron Glory tackles the science behind the game. With over 200 of the rarest artifacts from the Pro Football Hall of Fame, including legendary gear, photos, and documents chronicling the cultural phenomenon that is football today.  The exhibit captures the essence of the Hall of Fame experience.
Many of the artifacts are being exhibited for the first time. This interactive multimedia experience also includes new material from NFL Films, immersive fan experiences and a specially-designed “Hometown Tribute” section to spotlight the local teamRoy picture3. “We’re always looking for new and innovative ways to extend the experience of the Hall of Fame beyond our walls in Canton,” said Joe Horrigan, vice president-communications/exhibits at the Pro Football Hall of Fame.

This window into time, charts the history of the game, artifacts including a 100-year-old leather Roy picture4helmet, early versions of the football, a Tiffany’s-crafted Vince Lombardi Trophy, game balls and jerseys. One exhibit focuses on technological breakthroughs, including ones that failed, while another examines the broader cultural implications of the game, such as efforts to integrate African-Americans into the previously all-white league.

Whether you’re a child or an adult, male or female, there’s a lot here to learn about the history and science of football.

Sabemos que tenemos buenas historias que contar.  Nosotros sabemos de héroes anónimos, gente común y corriente realizando trabajos extraordinarios que los distingue y los convierte en ejemplos a seguir por otros.  Nosotros en Arizona, también sabemos que frecuentemente las cosas son difíciles, pero a pesar de esto, nos las ingeniamos para realizar trabajos con éxito y cumplir con nuestra misión.

Una de nuestras historias está programada para debutar en la pantalla de plata. Spare Parts es la historia de ficción basada en los hechos reales del club de robótica de la escuela High School Carl Hayden y de cómo ese equipo le ganó a estudiantes de las mejores universidades del país en una competencia de robots bajo el agua.  La película comenzará a exhibirse en Enero  16 a través de la nación, después de una emocionante premier en Enero 6en los cines Tempe Harkins Theaters 16.

La película, estelarizada y producida por el comediante George López cuenta la historia de 4 jóvenes inmigrantes de la escuela High School al oeste de Phoenix quienes, guiados por un maestro llamado Fredi Cameron, logran competir en contra de los estudiantes de las más importantes universidades del país en una competencia de robos bajo el agua.  Nosotros en Arizona sabemos que  “Fredi Cameron” es un personaje de película, compuesto por los maestros de la vida real  Fredi Lajvardi y Dr. Allan Cameron, quienes por décadas se han dedicado a enseñar promover la ciencia y tecnología.

También estelarizando en Spare Parts están los actores  Marisa Tomei, Jamie Lee Curtis, y jóvenes actores que dan vida en la pantalla a Lorenzo Santillán, Luis Aranda, Cristian Arcega  and Oscar Vázquez.

La película viene después de múltiples exhibiciones exitosas del documental  Underwater Dreams dirigido por  Mary Mazzio, quien lleva la saga de los 4 de Carl Hayden en gran detalle además de lo que pasa en la vida de los protagonistas después de la competencia y los efectos transformadores de sus acciones una década atrás. También existe un libro a la venta llamado Spare Parts por el escritor Josh Davies el cual está adquiriendo buenas críticas.

La mejor parte de todo es que son nuestras historias.  Todos nosotros que apoyamos la educación en las áreas de ciencia y tecnología nos encontramos con chicos como los de Carl Hayden en las escuelas de nuestras comunidades: llenos de talento y de potencial. Nosotros trabajamos, damos nuestro tiempo como voluntarios y/o pertenecemos a consejos de organizaciones para ayudar a aquellos que podrían verse como “de bajos recursos” y los ayudamos a sacar su mayor potencial,  aun en campos tan difíciles como los de ciencia, tecnología ingeniería y matemáticas (STEM).

Así que ésta es nuestra oportunidad de celebrar en grande, ir al cine, recomendar el documental, el libro y seguir trabajando.

We know we have good stories to tell.  We know of unsung heroes, common people doing extraordinary things that set them apart to become role models for others.  We are Arizonans and we know sometimes things are difficult but we manage to successfully do the job.

One of our Arizona stories is now set for the silver screen.  Spare Parts, the fictionalized account of the Carl Hayden High School Robotics team win against top universities in an underwater robotics competition will be showing at movie theaters all over the country, starting January the 16th, after an exciting worldwide premiere, on January the 6th at Tempe Harkins Theaters 16.

The movie, starred and produced by George Lopez, tells the story of 4 immigrant kids from a High School in west Phoenix who, guided by an inspiring mentor Fredi Cameron, manage to compete against top college students in a sophisticated tech competition.  We know “Fredi Cameron” is the composite character for Fredi Lajvardi and Dr. Allan Cameron, decades long STEM teachers and mentors (wink-wink).

Also starring on Spare Parts are Marisa Tomei, Jamie Lee Curtis and young actors playing the parts of Lorenzo Santillan, Luis Aranda, Cristian Arcega  and Oscar Vazquez.

The movie comes after a very successful documentary called Underwater Dreams by director Mary Mazzio, who brings the Carl Hayden 4 saga in great detail plus what happened to the lives of the persons involved, the transformative ripple effects of their actions. Also a book called Spare Parts by Josh Davies is being sold, achieving good reviews.

The best part of the all is that is one of our stories. We all STEM supporters encounter kids like the Carl Hayden four, talented, young people full of potential all the time. We work, volunteer and serve on non-profit boards so kids that may look underprivileged raise to the top and achieve great things even in difficult fields as science, technology, engineering and math (STEM).

So this is the opportunity to celebrate big, to recommend the movie, the documentary, the book, roll up our sleeves and keep working.

If one looks across intellectual history, it seems that times of great collaboration throughout the scientific community correlate with some of the greatest periods of innovation. In the seventeenth century, inventors such as Galileo would share ideas within their scientific community, building upon each other’s notions and gadgets. This is the spirit that underlies today’s ‘Maker’ culture; networking, sharing, peer-to-peer interactions inspiring creativity and continual development.

Communications Manager, Rachel Sutherland, similarly describes the culture of Intel Corporation: “Intel is all about being open to new ideas, and creative problem solving. It’s not a competition, it’s about great ideas and bringing the best ideas forward.” It’s this spirit of collaboration that has spurned Intel’s involvement with today’s ‘maker community’. In fact, Sutherland explains that Intel considers themselves to be a company that was founded by makers. “Our employees are making the brains of computers and computing devices for their day job; then they take those skills to apply to their hobby as makers. That’s why the maker community is such a perfect fit for Intel and Intel employees. It’s just this wide open forum where anything goes. You can apply your creativity and ingenuity and make things happen. Making is very near and dear to Intel because we have so many makers within our ranks.”

Intel is also contributing unique technology for use within the maker community, such as their aptly named ‘Galileo Board’.  This development and prototyping board was specifically designed by Intel for makers, students, educators, and DIY electronics enthusiasts.  “The Galileo Board is a development that allows you to computerize your invention,” Sutherland describes. “You can apply computing power to something that would otherwise just be a static device, making it even more interesting and powerful and creative. All that computing power can turn a simple mechanical device into some kind of automated device, almost becoming intelligent itself.”

Intel will feature the Galileo Board at its booth at the Chandler Epic Fest, part of the Arizona SciTech Festival, on February 7 in downtown Chandler, “right in our backyard,” Sutherland proudly declares. “We’re really focused on getting makers around the world connected to Intel technology because it’s powerful and it can enable so much. Additionally, we’ll be inviting our employees to showcase their creations at individual booths at the event.”

“The atmosphere of a maker fair is very inspiring,” Sutherland tells. “It’s really such a tight knit community of people who identify themselves as makers. It’s not about competition – it’s about creativity and celebrating everyone’s success and just marveling at the cool ideas that people can come up with. It’s not about who has ‘the best’ – it’s about recognizing your peers and their brilliance, their creativity, and their dedication.”

As a Bronze level sponsor, Intel is a proud supporter of SciTech Fest in Arizona, “because it’s a celebration of STEM, of creativity, of community and it brings together everything that goes into making Intel technology great. It’s sharing ideas, its showcasing ideas, and it’s about including everyone – all ages, all backgrounds, everyone’s welcome. There’s no exclusive club here – it’s for everyone.”

And you never know where that next great idea is going to come from.

2STEM Matters

STEM Matters Manager: Marisa Ostos

Stem cell research has been a highly-debated topic of conversation among politicians, scientists, and the everyday citizen. You may have heard about the many contributions stem cell research has made in the health field, such as its success in helping bone marrow transplant patients. On another note, you may also have heard of people’s disapproval of stem cell research due to the way it can be conducted.  But rather than listening to others state that stem cell research is “good” or “bad,” let’s delve into the basics of what stem cells are and how stem cell research works.

From the moment of conception, each one of us starts out as a single, fertilized cell known as a zygote. This single-celled zygote contains the basic genetic material (DNA) from both our father and our mother, which ultimately helps us develop into the person we are today. In less than two days, the single zygote cell divides into two cells, which only 15 hours later divides yet again. After just one week, what was once a single cell has now become a blastocyst, a “berry-like” structure the size of a pin that is composed of hundreds of cells! It is the blastocyst that eventually makes its way down to the woman’s uterus where from there, a baby will continue to grow until its birth.

We humans are made of billions upon billions of cells, each serving a specific function for the continued growth and development of our body. One of these types of cells within are body are stem cells, “immature cells that have the potential to become specialized into different types of cells throughout the body” (American Medical Association). Groups of cells together form the different tissues that make up our body, and the reason these stem cells are so special is because they, as immature cells, can either literally become any type of cell in the body (which is what embryonic stem cells do), or can serve to repair specific tissues within our body because of their dividing and specializing capabilities (which is what adult stem cells do).

Of course, scientists do obtain stem cells from different resources, which is where the controversy often comes into play. Of the two types of stem cells (adult vs embryonic), adult stem cells can easily be removed from our own tissue with very little, if any effect on us (*Note: the sample size of the tissue can be quite small). Embryonic stem cells, on the other hand, are “derived from multicellular embryos that have been cultured in the laboratory.” No, a researcher does not take cells from an embryo that is already growing inside of a mother. Rather, these stem cells may come from a variety of sources: Spare embryos created via in vitro fertilization that were not needed for infertility treatment; Adult tissue such as bone marrow; An empty egg cell into which DNA from an adult cell is placed; Mature adult cells that were pre-programmed to behave like stem cells (cool, huh?); Blood cells from an umbilical cord; etc.  Yes, there are a variety of places that these stem cells come from, but do know, too, that any scientist who does research follows guidelines to do their research in the most ethical, humane, and respectful manner possible.

Now that you know where stem cells come from and that they can become or help repair almost any type of cell in the body (such as cell that replaces disfunctional bone marrow or a cell that helps repair the lining of the heart), what are they used for? Well, the possibilities for their use are endless! Right now, stem cells “provide life-saving treatments for patients with leukemia, lymphoma, other blood disorders, and some solid tumors.” They help in bone marrow transplants…. With their potential to become any type of cell in the body, it is also possible that these cells can ultimately help to prevent or cure diabetes, Parkinson’s disease, Alzheimer’s disease, strokes, hearing loss, arthritis, and so much more. Maybe one day these single cells can be used to replace a leg someone may have lost years ago, or even more, maybe they can be used to create a brand new human heart! Scientists are already doing the research to solve these problems using stem cells!

So yes, while various sources of stem cells can be debatable, it is important to remember again that scientists who do stem cell research do so in the most ethical and human way possible, and even more, they are uncovering each day more and more information that may eventually help prevent or cure hundreds upon hundreds of the world’s problems today, all because of a single cell. What a wonder science is!

Arnold’s Pickle House es un edificio que trae muchos recuerdos, que está en la esquina de Van Buren y la calle 14th. Es un almacén viejo y abandonado decorado con una imagen antigua de un pepino con ojos, boca, brazos y piernas, corriendo con una gorra de béisbol. Adentro, pepinos solían ser procesados y transformados en “pickles”-pepinillos, años atrás.

El edificio ha sido abandonado hace tiempo, pero gracias a Chicanos por la Causa (CPLC), una de las más importantes organizaciones de desarrollo comunitario de Arizona, pronto volverá a la vida como un centro de creación, de STEM, de desarrollo de productos e ideas.

Chicanos por la Causa cerró el trato de adquirir el edificio el pasado mes de Noviembre gracias a un estímulo monetario del gobierno federal de 3 millones del Departamento de Comercio y Desarrollo Económico, con el propósito de crear un espacio como los llamados “maker” para la creación de productos e incubar negocios.

“La idea es crear nuevos negocios aquí. Las maquinarias y equipo que estarán disponibles en este edificio darán la oportunidad a emprendedores para construir prototipos, desarrollar productos que podrán ser vendidos”, dijo David Adame, Jefe de Desarrollo de Chicanos por la Causa.

“Si vienes con una nueva idea y diseñas un prototipo, te ayudaremos a hacer una impresión en 3 dimensiones. Entonces tú podrás ir a promover tu idea. Nosotros te podremos ayudar con órdenes de manufactura”, explico David.

CPLC está planeando a mantener elementos del edificio antiguo, incluyendo el nombre y el pepinillo para conectar el pasado con el presente y el futuro.

Este centro representa una gran oportunidad para la comunidad central de Phoenix al ofrecer un espacio creador o “maker space”, hacer crecer el movimiento emprendedor en Arizona y atraer creadores de las escuelas high schools, colegios comunitarios, universidades y expertos del público en general.

CPLC planea que los trabajos de construcción comenzarán después de las fiestas decembrinas y espera tener el espacio listo para usarse para Junio del 2015.
