Tour de Sys: The Traveler's View of a Network

submitted by: christian.thiemann

Analyzing the structure of complex networks like the US Aviation System can be very difficult, but one way to simplify this problem is to consider only the flights on the shortest routes from one specific airport to every other. For each airport, this gives us a different perspective on the network from which we can examine its statistical properties.

Pigment

submitted by: schulzbu
The video is based on an experiment of a Plant physiology course (HORT301) for Horticulture and Biology students. It is a student production geared towards middle school, highschool students and undergraduates as well as viewers who are interested in plant science. It depicts how flower pigments are analyzed using thin layer chromatography (TLC) and spectrophotometry. Investigations that shed light on the chemical and physical behavior of flower pigments are also shown as the isolated...

PSI-Are my soybeans wearing different genes?

submitted by: schulzbu
The video PSI – Are my soybeans wearing different genes? is inspired by the popular TV show “CSI-crime scene investigations”. Here, however, the investigators are solving cases in the field of plant science investigations (PSI). The stunning phenomenon that soybean plants can survive herbicide treatments and grow on fields without weed competition is investigated using DNA extraction, Polymerase chain reaction (PCR), gene analysis etc. Transgenes are found that make the soybean plants...

Obama Inauguration: A Positive Change in Federal Stem Cell Research Policies

submitted by: CIRMTV
On March 9, 2009, President Barack Obama signed an executive order to lift a ban on federal funding for embryonic stem cell research that had been in place since August, 2001. In this video, Susan Fisher, director of the UCSF Human Embryonic Stem Cell Center, and Alan Trounson, president of the California Institute for Regenerative Medicine, discuss how the federal ban affected stem cell researchers and how President Obama's stem cell research policies will bring new opportunities in this...

Jerome Zack Talks About Creating iPS Cells

submitted by: CIRMTV
In 2006 scientists learned how to create a pluripotent stem cell out of a human skin cell. These cells, called induced pluripotent stem (iPS) cells have many of the characteristics of embryonic stem cells including the ability to create mature cell types. Dr. Jerome Zack has a CIRM grant to create iPS cells that could be used in human therapies. Zack is Associate Director, UCLA AIDS Institute, professor of Medicine, Microbiology, Immunology & Molecular Genetics, and a scientist with the...

Alan Lewis: Embryonic Stem Cell Therapies for Diabetes

submitted by: CIRMTV

Embryonic stem cells have the potential to help treat 70 or more diseases, but developing those new therapies will take time. Alan Lewis is president and CEO of Novocell, a La Jolla-based company that has been developing a potential therapy for diabetes. Novocell has a CIRM grant to assemble a team of researchers who will accelerate the time it takes to get that potential therapy to the FDA for clinical trials.

Cheese and Microbes - MicrobeWorld Video - Ep. 28

submitted by: MicrobeWorld
Fine cheeses are like fine wines. Producing and aging them properly is both an art and a science. From cave-aging to the use of raw milk, watch Dr. Catherine Donnelly, co-director of the Vermont Institute for Artisan Cheeses, describe the microbial world of cheese. Listeria and Salmonella are just a couple of the pathogens that pose a risk to cheese consumers. In this episode of MicrobeWorld Video, Dr. Donnelly explains how these risks are mitigated through strict processing...

Mark Mercola: Differentiating Embryonic Stem Cells into Adult Tissues

submitted by: CIRMTV
A major challenge in developing stem cell-based cures for disease is maturing those cells into adult cell types that can be used for transplantation or to study human disease. Mark Mercola has a CIRM grant to derive heart muscle cells from embryonic stem cells. In this video, Dr. Mercola describes how stem cells could one day be used for transplantation, for testing new drugs for side effects on heart muscle cells, and to learn about how the heart cells mature and develop. That knowledge...

Novel Spinal Cord Stimulator Sparks Hope for Parkinson’s Disease Treatment

Content: The future treatment of Parkinson’s disease may target the spinal cord instead of the brain to help alleviate the slow, rigid movements and tremors that are the hallmarks of the disease. Researchers at Duke University Medical Center have developed and tested a first-of-its-kind device that rapidly restored motor function in mice with the symptoms of Parkinson’s disease. Miguel Nicolelis, M.D., Ph.D., senior study investigator and Anne W. Deane Professor of Neuroscience: "We...
