Micromechnical Biosensors and their Integration with Aptamer-based Receptor Molecules
This site is one of many on \\\\\\\"nanoHUB.org\\\\\\\" which highlights availability of on-line simulations. This particular one provides a video of a research seminar on the topic of micromechanical biosensors focusing on aptamer-based receptor molecules. The quality of the graphics in the video is not high - mainly, the smallness of the visuals makes it difficult to decipher the contents. However, the information content, as delivered and described verbally, is coherent and useful. The i
Panel: "Clearing the Air: Managing Air Quality to Benefit Health and Climate in India"
Sarath Guttikunda, assistant professor at Desert Research Institute and founder of Urban Emissions.Info in India; William K.M. Lau, chief of the laboratory for atmospheres at NASA's Goddard Space Flight Center and senior science adviser to the Hong Kong Observatory; and Danielle Meitiv, climate specialist at the Clean Air Task Force, will discuss this topic.
7.342 Systems and Synthetic Biology: How the Cell Solves Problems (MIT)
A millennial challenge in biology is to decipher how vast arrays of molecular interactions inside the cell work in concert to produce a cellular function. Systems biology, a new interdisciplinary field of science, brings together biologists and physicists to tackle this grand challenge through quantitative experiments and models. In this course, we will discuss the unifying principles that all organisms use to perform cellular functions. We will also discuss key challenges faced by a cell in bot

Description not set
Students explore the basic physics behind walking, and the design and engineering of shoes to accommodate different gaits. They are introduced to pressure, force and impulse as they relate to shoes, walking and running. Students learn about the mechanics of walking, shoe design and common gait misalignments that often lead to injury.
Students examine how the orientation of a photovoltaic (PV) panel relative to the sun affects the efficiency of the panel. Using sunshine (or a lamp) and a small PV panel connected to a digital multimeter, students vary the angle of the solar panel, record the resulting current output on a worksheet, and plot their experimental results.
This lesson culminates the unit with the Go Public phase of the legacy cycle. In the associated activities, students will use linear models to depict Hooke’s law as well as Ohm’s law. To conclude the lesson, students must apply they’ve learned throughout the unit to answer the grand challenge question in a writing assignment.
Students are introduced to passive solar design for buildings — an approach that uses the sun’s energy and the surrounding climate to provide natural heating and cooling. They learn about some of the disadvantage of conventional heating and cooling and how engineers incorporate passive solar designs into our buildings for improved efficiency.
Students are given a variety of materials and asked to identify if each material as a solid, liquid or gas. They use their five senses — sight, sound, smell, texture and taste — to identify the other characteristics of each item.
This activity shows students the engineering importance of understanding the laws of mechanical energy. More specifically, it demonstrates how potential energy can be converted to kinetic energy and back again. Given a pendulum height, students calculate and predict how fast the pendulum will swing by using the equations for potential and kinetic energy. The equations will be justified as students experimentally measure the speed of the pendulum and compare theory with reality.
Students learn about energy flow in food webs, including the roles of the sun, producers, consumers and decomposers in the energy cycle. They model a food web and create diagrams of food webs using their own drawings and/or images from nature or wildlife magazines. Students investigate the links between the sun, plants and animals, building their understanding of the web of nutrient dependency and energy transfer.
Students learn about the Earth’s only natural satellite, the Moon. They discuss the Moon’s surface features and human exploration. They also learn about how engineers develop technologies to study and explore the Moon, which also helps us learn more about the Earth.
Students become familiar with the Engineering Design Process as they design and build prototypes for a chair. The miniature chair must be sturdy and functional enough to hold a wooden, hinged artist model or floppy stuffed animal.
Students expand upon their understanding of simple machines with an introduction to compound machines. A compound machine — a combination of two or more simple machines — can affect work more than its individual components. Engineers who design compound machines aim to benefit society by lessening the amount of work that people exert for even common household tasks. This lesson encourages students to critically think about machine inventions and their role in our lives.
In this activity, students reinforce their understanding of compound machines by building a catapult. This compound machine consists of a lever and a wheel-and-axel. Catapults have been designed by engineers for a variety of purposes — from lifting boulders into the air for warfare to human beings for entertainment; the projectiles in this activity are grapes for a magic act. Given the building materials, students design and build their catapult to launch a grape a certain distance.
Fact sheets are provided for several different energy resources as a starting point for students to conduct literature research on the way these systems work and their various pros and cons. Students complete a worksheet for homework or take more time in class for research and presentation of their findings to the class. This approach requires students to learn for themselves and to teach each other – rather than having a teacher lecture about the various sources and systems.
