“We Are Stardust: Genesis of the Elements” with Mary Barsony, Ph.D.

Marin Science Seminar Presentation: “We Are Stardust: Genesis of the Elements” Dr. Barsony’s talk focuses on how stars shine and how they have generated the elements. (February 3, 2010) Get the flyer here.
One of the fundamental goals of astronomy and astrophysics is to understand how the Universe and its constituent galaxies, stars, and planets formed, how they evolved, and what their destiny will be. Dr. Barsony’s research is focused on the formation of stars out of the raw material provided by tenuous interstellar gas found in frigid clouds in our Galaxy. Since the present birthplaces of stars are hidden by interstellar dust mixed in with the gas, exploring the detailed mechanisms involved in star (and planetary system) formation requires observations at wavelengths whose passage is relatively unimpeded by the intervening dust: radio, millimeter, submillimeter, infrared, and X-ray wavelengths. 
Through submillimeter observations in the early ‘90’s, Dr. Barsony helped identify the first true protostar—an object surrounded by infalling gas that is in the process of accumulating the mass it will have as a full-fledged star. Such objects are rare, and the focus of intense current (and future) study, with space-based observatories such as the Spitzer Space Telescope, the Herschel Observatory, and the planned JWST (Hubble’s replacement that wil operate at infrared wavelengths). 
Dr. Barsony is Adjoint Professor of Physics & Astronomy at San Francisco State University and a Research Scientist at the Space Science Institute. She earned her Ph.D. from CalTech and her S.B. from MIT.

How to Bring Solar Energy to Seven Billion People

“How to Bring Solar Energy to Seven Billion People” with Cyrus Wadia, Ph.D.
November 4, 2009


Dr. Wadia is a pioneer in bringing a multidisciplinary approach to solving the complicated issue of renewable energy. Join him in a lively discussion on the promise -and the pitfalls – of solar energy. Download the flyer here.
 

In the city of San Rafael, the only way solar energy can be cost-effective is if the local government provides generous subsidies. That’s true just about everywhere in the world. But what if there were a photovoltaic technology that was so cheap and so easy to install that even the poorest and most remote villages of the world could gain access to electricity? In this presentation, learn about discoveries of new materials that can make solar energy a reality for billions.
By exploiting the powers of nanotechnology and taking advantage of non-toxic, Earth-abundant materials, Cyrus Wadia has fabricated new solar cell devices that have the potential to be several orders of magnitude less expensive than conventional solar cells. And by mastering the chemistry of these materials – and the economics of solar energy – he envisions bringing electricity to the 1.2 billion people now living without it.
Dr. Wadia holds an MS in Chemical Engineering from MIT and a PhD in Energy Resources from UC-Berkeley. He is currently a postdoctoral fellow at the Lawrence Livermore Laboratory in Berkeley. Dr. Wadia spent six years in the high tech industry, has specialized in launching new technologies to market and has completed several successful new product introductions. Presently, Cyrus continues his work helping companies take technology to market as part of an independent consulting practice he began in 2001.

“Stimulating the Brain with Electricity and Stem Cells”

“Stimulating the Brain with Electricity and Stem Cells”
with Daniel Lim MD PhD
October 21, 2009

Dr. Lim will discuss Neurosurgery for Parkinson’s Disease and other Tremor Disorders, treatments for such disorders ranging from Deep Brain Stimulation (delivery of electrical currents), and the future of stem cell based therapies of such disorders.

Dr. Lim is Assistant Professor in Residence of Neurological Surgery and Director of Restorative Neurosurgery at the UCSF School of Medicine. The focus of his research is on neural stem cells and neurogenesis. He is particularly interested in the molecular biology of the population of neural stem cells found in the subventricular zone (SVZ). For neural stem cells to make neurons, daughter cells need to express certain sets of genes while repressing others. The maintenance of such lineage-specific transcriptional programs is in part regulated by chromatin structure – the “packaged” state of DNA with histone proteins. Recently, Dr. Lim’s work has revealed that the chromatin remodeling factor called Mixed Lineage Leukemia-1 (MLL1) is essential for postnatal neural stem cells to make new neurons. Currently, his work focuses on the molecular mechanisms by which MLL1 specifies a transcriptional program instructive for neurogenesis. In the future he hopes to define the genetic programs and molecular mechanisms that guide the formation of neurons and glia from SVZ neural stem cells, and translate these discoveries into cell-based and genetic therapies for human neurological diseases.
In addition to his basic science interests, Lim has a clinical interest in stereotactic neurosurgery and has worked to study deep brain stimulation for movement disorders including Parkinson’s disease, essential tremor, and atypical tremors resulting from multiple sclerosis or stroke.

Smashing Protons!

“Smashing Protons!: Exploring Nature’s Fundamental Particles and Forces with the Large Hadron Collider” with Beate Heinemann, Assistant Professor of Physics, UC-Berkeley

(September 30, 2009)

Dr. Heinemann’s experiment recently became famous when it was featured in the blockbuster movie “Angels & Demons” with Tom Hanks. She will discuss particle physics and her work with the Large Hadron Collider in Switzerland.

“The field of “particle physics” tries to understand the physics of the most fundamental building blocks of matter. How many such building blocks are there? How do they relate to each other? Why are they there? Currently we do not have a good theory why we have any mass at all, even though of course we know that all matter has a mass. There are, however, many theories about why this might be and the goal of my experiment is to prove or disprove them, or to maybe find completely unexpected phenomena that will then need to be explained. One exciting possibility is that we find extra dimensions of space that could even result in the production of mini-blackholes. My experiment is called ATLAS and is situated at the “Large Hadron Collider” (abbreviated as LHC) that is located in Switzerland. There are more than 2000 physicists on my experiment, and many engineers and technicians: all of them collaborate with each other to answer some of the most basic and fundamental questions of Science today. In my talk I will describe how this experiment works and what we hope to discover there.”

Detecting Illicit Nuclear Material with Edward Morse, PhD

Join us for the kick-off to the Marin Science Seminar Fall 2009 season!

Detecting Illicit Nuclear Material with Professor Edward Morse
Wednesday, September 23rd, 2009, 7:30 – 8:30 pm
Terra Linda High School, San Rafael, Room 207

Detecting nuclear material at ports of entry into the United States and at other locations is a daunting problem but is an essential element of a counterterrorism strategy for the country. A major difficulty in detection is the minimization of false-positive signals from a wide variety of cargo containing NORM, or naturally occurring radioactive material. One technique which looks promising is the use of nuclear resonance fluorescence (NRF) for detecting special nuclear material such as U-235. We have embarked on a five year program at UC Berkeley, called DoNuTS (Domestic Nuclear Threat Security), which looks at various aspects of the threat detection problem. This program will be discussed, with emphasis on the physics and technology of NRF as well as other aspects including materials science, computer machine vision, sensor networks, and basic nuclear physics research.

Prof. Edward Morse is a professor of Nuclear Engineering at UC-Berkeley and has a thirty-year involvement in teaching and research at Berkeley in the areas of applied physics, nuclear technology, electronics, and mathematics.
