Science for the Public

Science for the Public is a grassroots nonprofit organization committed to the promotion of adult science literacy. The organization hosts public presentations by scientists at Boston Public Library, a community science TV series, and online science resources. Citizen participation is actively encouraged in the development of our programs and resources. Today, many of the most pressing issues of modern life require the expertise of scientists. Citizens must therefore have a reasonable understanding of science in order to function as responsible members of society. Further, as the pace of scientific discovery accelerates, modern citizens must be able to grasp new concepts and information that are reshaping our perspectives. Although the issue of science literacy is now being addressed at the K-12 level, there is no science curriculum for the adult population. And it is the adult population that votes, pays taxes and raises children.

The D-Lab at MIT: The People's Engineering Team

Wed, May 29, 2013

"Amy Smith, Founder and Director of the famous and award-winning D-Lab at MIT ('Design-Develop-Disseminate') discusses the D-Lab's unique innovative approach to improving life in the world's poorest nations. Collaborations of D-Lab engineering students and villagers in developing nations create effective tools and equipment to improve lives. The D-Lab collaborations demonstrate that the capability for innovation exists even in impoverished communities with very limited resources, and that people everywhere can learn to improve their lives significantly. The D-Lab is an outstanding humanitarian project and a very effective one. One objective is to help communities in developing nations to create engineering solutions for specific needs in health care (including prostheses), water purification, grain processing, and other concerns, using mostly the materials at hand. The D-Lab provides workshops to get people started, and soon villagers themselves develop equipment and even start businesses. The second objective of D-Lab is to engage MIT engineering students in the design-development-dissemination process. The D-Lab courses are so popular that students are accepted only by lottery. Engineering students and ordinary people collaborate on simple, elegant and inexpensive equipment that meets specific local needs around the world. D-Lab is a whole new way of learning for everyone involved."

Antarctic Fishes: Models for Climate Change and Human Disease

Tue, Jul 9, 2013

The notothenioid icefishes of Antarctica are among the most interesting examples of evolution. When the Southern Ocean formed, the blood of the icefish evolved unique 'antifreeze' properties that enabled them to survive the extreme cold of the Southern Ocean (temperatures of '1.8 to +1°C). In addition, the icefish skeletal structure changed, becoming much lighter in weight. These two adaptations ensured the survival of icefish while many other organisms became extinct at the time of the ocean temperature change. Dr. Detrich explains why the icefish were able to adapt while most other organisms in the Antarctic area became extinct when the Southern Ocean formed. He also discusses how blood and skeletal changes that were survival features for the icefish are features of disease 'anemia and osteoporosis' in humans. Professor Detrich brings to his research a broad and deep background in biochemistry, molecular biology and genomics. His work is providing significant insights into both climate change biology and medicine. Dr. Detrich has spent more than twelve field seasons in Antarctica, at Palmer Station and McMurdo Station and he describes, in this lecture, the excitement of 'research on the ice' and the climate changes in Antarctica he has witnessed over two decades. H. William Detrich, III, Ph.D., Professor, Marine Molecular Biology and Biochemistry, Department of Biology, Northeastern University; Principal Investigator for the United States Antarctic Program since 1984.

Journey to the Center of the Earth

Tue, Nov 5, 2013

"When Jules Verne published his classic Journey to the Center of the Earth in 1864, practically nothing was known about the Earth's interior. By this time, Charles Darwin had published On the Origin of Species, weather maps had become available, and Maxwell's equations for electromagnetic waves were used. In contrast, views of the Earth's interior did not emerge until well into the 20th century. How did the Earth, which seems so accessible to humans, remain a mystery for such a long time? In this presentation, Professor Ishii discusses challenges and techniques for studying the deep interior, and takes the audience on a modern journey to the center of the Earth. Miaki Ishii, PhD, Professor of Earth and Planetary Sciences, Harvard University, and member of the Harvard Seismology Group."

How TB Bacteria Evade Treatment

Tue, Dec 10, 2013

"Tuberculosis is one of the deadliest diseases in our crowded world, and by far one of the hardest diseases to conquer because TB bacteria are exceptionally clever at outwitting the antibiotics designed to arrest the disease. Professor Bree Aldridge has pioneered research that illuminates the mechanisms used by mycobacteria (TB) to evade medication. Scientists are now beginning to understand that identical cells are like identical twins: although genetically identical, individual cells can have surprisingly different characteristics. The Aldridge Lab studies the bacteria that cause tuberculosis. These cells vary in their response to antibiotic therapy, even in controlled laboratory conditions. The Aldridge team uses live-cell imaging and mathematical modeling to understand how TB cells differ from one another and how individual distinctions affect the response to antibiotics. In doing so, Dr. Aldridge and her group address a major obstacle in controlling tuberculosis, which is the lengthy multi-drug therapy currently required to effectively cure the disease. By understanding how some bacteria behave differently, they hope to identify more effective treatments. Bree Aldridge, PhD, Bree Aldridge, PhD, Assistant Professor of Molecular Biology and Microbiology at Tufts University School of Medicine; member of the Molecular Microbiology and Immunology program faculties at the Sackler School of Graduate Biomedical Sciences at Tufts; Adjunct Assistant Professor of Biomedical Engineering, Tufts School of Engineering."

Replacing Plastic: The Merits of Shrilk

Tue, Feb 4, 2014

Plastic is everywhere and has become a serious threat to the environment and to health. To replace plastic, materials scientists have looked to nature for examples. The target material has to be tough, light, and versatile --like compounds found in silk, insect wings, and shrimp shells. A very promising replacement based on such compounds has been developed by Javier Fernández of the Wyss Institute of Harvard. The material, which these scientists called "shrilk," is modeled on natural compounds. It is biodegradable and also biocompatible, meaning it can be used in medical applications including surgery. Shrilk can be produced inexpensively and it can be molded into complex shapes varying in stiffness and elasticity. Dr. Javier G. Fernández explains the urgent need to replace plastic, the challenge of developing innovative materials like shrilk, and the great many uses for this new material.

Conflicting Science on the Safety of Genetically Modified Food

Thu, Jun 12, 2014

Rarely has there been a time when food has divided society into two major warring camps. But that is the situation regarding genetically modified food (aka genetically modified organisms or GMOs). One camp proclaims that genetically modified crops represent the future of food. The other camp believes it is a corporate conspiracy that will contaminate and endanger the world's food supply. Can science bring us closer to the truth about GMOs?
