"A Time Bomb Inside of You": Social Service Organizations Advocate an Improved Federal Response to A
In 1981, the U.S. medical community noticed a significant number of gay men living in urban areas with rare forms of pneumonia, cancer, and lymph disorders. The cluster of ailments was initially dubbed Gay-Related Immune Disease (GRID), but when similar illnesses increased in other groups, the name changed to Acquired Immune Deficiency Syndrome (AIDS). The mid-1980s saw a number of advances toward understanding and treating the disease, but no vaccine or cure was forthcoming. Gay advocacy and co
"A Devil to Tempt and a Corrupt Heart to Deceive," John Dane Battles Life's Temptations, ca. 1670s.
John Dane, a tailor, was born in Berkhampstead, England, around 1612. In the late 1630s, which he recollects here as a period of "a great coming to New England," he and his family emigrated to Ipswich, Massachusetts. He died in Ipswich in 1684. Dane's parents, like many Puritan parents, raised their children to carry what historian Philip Greven calls an "inner disciplinarian" within their own consciences at all times. Dane's mother reminded him: "Go where you will, God will find you out." In th
'Borders' begins with a short dramatic piece that introduces the issues of complicity, resistance, and boundaries. This work continues to investigate these themes in the style of a documentary. In the prologue, actor Steve Buscemi plays Ted, a young scientist who goes to work at a large scientific research facility. Here he develops ideas that, much to the dismay and rebuff of his jealous fellow researchers who gather around a vending machine, are embraced by his supervisors. The young scientist
Middle School Portal: Math and Science Pathways (MSP2)
This is a biographical sketch of William Hyde Wollaston. Wollaston studied and made advances in many scientific fields, including chemistry, physics, botany, crystallography, optics, astronomy and mineralogy. He is particularly noted for being the first to observe dark lines in the spectrum of the sun, discovering the elements palladium and rhodium, and proving the elementary nature of niobium and titanium. Wollaston also developed a method for making platinum metal malleable, establishing an eq
Global Competition: How We Can Win
6th Annual Berkeley in Silicon Valley Symposium In his recent best selling book, The World is Flat: A Brief History of the Twenty-first Century, Pulitzer Prize-winning author Thomas Friedman writes that the lowering of trade and political barriers and profound technological advances in global connectivity have enabled a "flat world" where it is possible to do business or almost anything else instantaneously and with billions of people. According to Dean Richard Newton, it is perhaps ironic that
Fundamentals of Nanoelectronics
The development of "nanotechnology" has made it possible to engineer materials and devices on a length scale as small as several nanometers (atomic distances are ~ 0.1 nm). The properties of such "nanostructures" cannot be described in terms of macroscopic parameters like mobility or diffusion coefficient and a microscopic or atomistic viewpoint is called for. The purpose of this course is to convey the conceptual framework that underlies this microscopic viewpoint using examples related to the
Homework for Resonant Tunneling Diodes
This homework assignment was created for EE 218 "Introduction to Nanoelectronics and Nanotechnology" (Stanford University). It includes a couple of simple "warm up" exercises and two design problems, intended to teach students the electronic properties of resonant tunneling diodes and carbon nanotubes, and how they can be used as components in real circuits. Students do their work via the Resonant Tunneling Diode Simulator and the MSL Simulator, which are both available online through NanoHub.or
When we apply the scientific method to real-world problems, often we can invent applications for the effects we observe even without understanding the origins of those effects. This process is commonly used in the development of new technologies; one example is the discovery of x rays. This curriculum unit is designed to encourage this investigative process through inquiry-based learning involving exploring, observing, and then applying the information gained. Light and its interactions with mat
Educational Technology and Society
Educational Technology and Society is a quarterly electronic journal that addresses "issues affecting the developers of educational systems and educators who implement and manage such systems." Published partly in association with the Learning Technology Task Force of the Institute of Electrical and Electronics Engineers, the journal often has special features or focuses; for instance, the October 2002 issue has several articles on recent advances and developments in learning technology. Other s
Keynote Presentation: Academic Perspectives
Very simply stated, systems biology attempts to “capture the dynamic nature of living systems.” To accomplish this, says Hood, you “have to bring together the flavors of biology, chemistry, computer science, engineering and physics,” among others. It’s a vast area to tackle. But with tools like the internet and digital
Bioengineering at MIT: Building Bridges Between the Sciences, Engineering and Health Care (Part Two
Glycomics, the study of sugars’ role in living systems, is a relative newcomer to the revolution in molecular biology. In fact, Ram Sasisekharan remembers how colleagues told him “not to work on carbohydrates -- that it was useless.” But his research has shown that glycans, observed as long chains or intricat
Nanotechnology and the Study of Human Diseases
Subra Suresh fleshes out the promise of nanotechnology, at least in regard to our understanding of disease. His talk, which focuses on malaria and its impact on red blood cells, demonstrates how the fields of engineering, biology and medicine are converging.
To function properly, he explains, a red blood cel
Inspired by the vast potential of bioengineering, ordinary people are seeking their inner Frankenstein -- doctor, not monster. Two speakers who know their way around Petri dish and beaker discuss the possibilities and pitfalls of do-it-yourself biology with an MIT Museum crowd.

A pioneer in a “dangerously hot research area,” Drazen Prelec peers into the human brain while it makes decisions. In his corner of the new field of neuroeconomics, Prelec uses a functional magnetic resonance imaging (fMRI) machine to scan minds pondering the pros and cons of purchasing and selling products like
Deep Brain Stimulation Therapy for Movement Disorders
New tools are enabling neuroscientists to break therapeutic ground against daunting disorders like Parkinson’s Disease (PD). Andres Lozano is one “of a small group of heroes,” in Ann Graybiel’s estimate, whose work is yielding astonishing advances on a variety of fronts.
Treatments for PD, a progressiv
The Future of Nuclear Energy
Nuclear energy will emerge either as a solution to the twin crises of global warming and a secure energy supply, or global catastrophe. Within this panel at least, there doesn’t seem to be a comfortable middle ground.
MIT’s Andrew Kadak, one of the two speakers arguing the necessity of nuclear energy, advance
Technology and the Future Warrior: Protecting Soldiers in the 21st Century
The Super Soldier has one foot out of the lab, and will be reporting for battle by 2020. “Dutch” DeGay’s Army researchers have begun to “rebuild the soldier from the skin out.” Current infantrymen, stationed in Iraq and Afghanistan, must shoot, move and communicate carrying upwards of 100 pounds of personal armor an
Nicholas Pearce is a proud advocate of programs that help young people from urban areas transition into higher education. He has not only benefited from such programs, but has given back through his participation as a volunteer, mentor, and speaker. As a high schooljunior, he attended MIT's six-week summer program, Minority Introduction t
Liberty by Design
Recalling a lecture he gave at MIT in 2005,
Alan Davidson returns to the questions of the impact of public policy on the way technology is evolving in the Internet space.
Instead of viewing it as a lawyer for a public policy interest group—his previous role—he now approaches it from his new perspective as a publ
Following on from the advances made in diagnosing disorders using genetic testing, this unit looks at the possibilities for genetic therapies. Two approaches to gene therapy are discussed: correcting genes involved in causing illness; and using genes to treat disorders. Before closing on a discussion of the issues around 'designer babies' somatic gene therapy and germline gene therapy are discussed.
