Museum of Science, Boston

One of the world's largest science centers, the Museum of Science, Boston attracts 1.6 million visitors a year through vibrant programs and over 550 interactive exhibits. Its mission is to stimulate interest in and further understanding of science and technology and their importance for individuals and society. Other features include the Thomson Theater of Electricity; Current Science & Technology Center; Charles Hayden Planetarium; Gilliland Observatory; and Mugar Omni Theater. The Museum's exhibit plan, Science Is an Activity, has been awarded several National Science Foundation grants and profoundly influenced exhibit development at other major science centers.

  • Growing New Body Parts

    Tue, May 3, 2005
    Tissue engineering involves the application of the principles and methods of engineering and the life sciences towards the development of biological substitutes to restore, maintain, or improve functions of tissues or organs. It is expected that engineered tissues can help address the growing problem of tissue and organ failure by implanting tissue substitutes grown in the laboratory that can provide immediate function and integrate with surrounding host issues. The field relies on an interdisciplinary approach to solve complex tissue and organ problems in the laboratory. Teams of engineers, biologists and clinicians are essential to the successful engineering of these systems. Requirements for tissue engineering generally include a cell source (often stem cells), biomaterial scaffolds (the structures upon which the cells will stick, grow and produce new tissue) and a bioreactor (laboratory environment designed to mimic some of the conditions present during normal tissue development). With the advanced systems we now have, tissues similar to those in our body can be generated in the laboratory. As a result of active research in the area, new opportunities become available, including the repair and replacement of damaged or diseased tissues in the body, the use of these tissues for the study of disease formation and progression (such as cancer), and therapeutic treatments (such as to identify new drugs). We have prepared a set of four presentations to illustrate some of the exciting opportunities that tissue engineering offers to clinical medicine.

  • Doctors Without Borders in Niger

    Sat, Nov 5, 2005
    Milton Tectonidisas and Jonathan Spector describe Plumpy'nut, a revolutionary new approach that Doctors Without Borders is using to treat malnourishment in Niger; and they discuss what this technique could mean for how the organization will respond to nutritional crises and famine in the future. Doctors Without Borders has traditionally treated malnourished children through both supplementary feeding centers for the moderately malnourished and inpatient therapeutic feeding centers for the most severely malnourished. The organization is now moving toward a new approach, enabling medical teams to reach tens of thousands more children. Thanks to a new therapeutic nutritional technology called Plumpy'nut, Doctors Without Borders now treats severely malnourished children on an outpatient basis, allowing children to return home when they would normally be hospitalized. With the help of Plumpy'nut, Doctors Without Borders has a 90% cure rate in its outpatient programs in Niger and has treated 40,000 children so far in 2005.

  • From Stem Cells To Cancer Cells

    Fri, Oct 21, 2005
    Fernando Camargo discusses his research on how cancer arises, what can be done to stop it, and whether cancer is related to stem cells. The human stem cells found in our bone marrow have the amazing ability to develop into different types of cells such as blood or immune system cells. This happens in all of us everyday, but we know little about how it happens. Camargo's research centers on figuring out how stem cells travel down their path to become a new bone or blood cell. Recently, new theories suggest that stem cells have some of the same characteristics as cancer cells. Figuring out how stem cells replicate themselves, divide into specialized cells, or even give rise to a cancer would provide answers for research scientists and maybe treatments for patients.

  • Nanotechnology: The Next Small Thing?

    Wed, Jan 21, 2004
    Nancy A. Burnham, W. Grant McGimpsey, and William Durgin discuss consumer products that take advantage of the possibilities of nanotechnology, and what we can expect to see on the market in the near future. The computer industry is continually working to make transistors smaller, cheaper, and faster. As systems become tinier, they behave in ways that are fundamentally different from those made on a macroscopic scale. Because of this great difference, nanotechnology presents new opportunities and possibilities.

  • AIDS: Learning From the Past, Looking Towards the Future

    Fri, Dec 3, 2004
    As a way of marking World AIDS Day on December 1st, the Museum of Science welcomes clinician and researcher Pride Chigwedere from Zimbabwe to comment on the past two decades of international efforts to stem the spread of AIDS. Looking to the future, Chigwedere talks about prevention and treatment strategies drawn upon our knowledge of the disease, and the people it affects, looking at Africa as a case study. This lecture is ASL interpreted.

  • Psychology of Surveys: Measuring Public Opinion

    Fri, Nov 5, 2004
    Barry C. Burden of Harvard University lectures on the science and technology behind measuring public opinion. How can we know what 200 million Americans think, feel, and know? Can telephone interviews with a few hundred people really describe public opinion? How much can answers be manipulated by rewording the questions? This lecture is ASL interpreted.

  • Life of a Drug: Clinical Trials and Tribulations

    Fri, Jan 21, 2005
    Timothy Maher follows the lifespan of a new chemical entity from initial discovery, through synthesis, preclinical and clinical testing, to approval, launch and post-marketing surveillance. Maher charts the ups and downs along the way from before a drug is approved, through marketing, and use and beyond; and he answers questions like: What is a "black-box" warning? Who's looking out for your well-being? Should "Fen-Phen" have ever happened? What about Vioxx? This project is supported by a Science Education Partnership Award (SEPA) from the National Center for Research Resources, National Institutes of Health. It does not necessarily represent the official views of NCRR or NIH.

  • Our Special Planet: A Cradle for Life

    Wed, Oct 23, 2002
    Peter D. Ward describes the unique traits of our solar system that helped life to gain an initial foothold. Once life arises, it survives tenaciously. Ward explains how important is it to have a Jupiter to divert threatening swarms of comets, a large moon to provide nurturing tides, and a crust of moving plates to recycle the stuff of our world. Despite the flood of newly discovered worlds, Ward argues that our planet is more precious than we may realize.

  • Secret Hunt for North American Diamonds

    Fri, Nov 7, 2003
    Award-winning journalist Kevin Krajick tells the amazing story of modern day prospectors in Canada's frozen North who did the impossible: found diamonds in North America. Hear about the technological tools these two men used, the geology that provides conditions where diamonds are formed, and the fortune found and claimed right under the noses of large multinational companies.
