Physics

A supernova remnant acts like a relativistic pinball machine by accelerating electrons to enormous energies. The blue, wispy arcs in this image of Cassiopeia A, the youngest supernova remnant in the Milky Way, show where the acceleration is taking place in an expanding shock wave generated by the explosion. The red and green regions show material from the destroyed star that has been heated to mil...

Irene Porro demonstrates how to use a 'sunspotter' to safely show the sun and sun spots on it to a group of Somerville schoolchildren in 2001. Porro, education and public outreach scientist at the MIT Kavli Institute, has recently helped secure a grant to develop a youth astronomy apprenticeship program at MIT.

This micropump developed by MIT researchers allows high speed flows through microchannels with an input of only a few volts of electricity, making it possible to create portable "lab on a chip" devices.
The three-dimensional, alternating current electro-osmotic pump consists of interdigitated stepped gold microelectrodes on a glass substrate.

MIT researchers have discovered that certain molecules can attach themselves to metallic carbon nanotubes without interfering with the nanotubes' exceptional ability to conduct electricity. At left, the high conductance state has two molecular orbitals, shown in green. Some molecules even let the nanotube switch between highly conductive, left, and poorly conductive (right, with one red molecular ...
