Cheap light: microlasers go deeper into the infrared to boost optical networking

Article Abstract:

Microlasers known as vertical-cavity surface-emitting lasers (VCSELs) are underdevelopment for use in future optical computers. VCSELs emit photons from the surface of the silicon wafer on which they are placed, as opposed the edge-emitting form factor in current optical computing technology.

Heavy-metal sweat: Does an infrared Sauna really detoxify the body?

Article Abstract:

An infrared sauna is a machine that is supposed to heat the body, not the surrounding air and produce sweat more efficiently. However, poison perspiration exudes from the pores when a user is exposed from an infrared sauna, according to claims made for the technology.

Faster, smaller, flatter

Article Abstract:

Karey Holland, a researcher at IBM Corp, has designed an innovative means of manufacturing computer chips through a process called chemical-mechanical polishing (CMP). Chips fabricated by CMP possess flatter surfaces, thus allowing more layer wirings to be incorporated to them.
