Nanotechnology in Cancer
2008-08-29 05:56:00
Nanoscale devices are somewhere from one hundred to ten thousand times smaller than human cells. They are similar in size to large biological molecules ("biomolecules") such as enzymes and receptors. As an example, hemoglobin, the molecule that carries oxygen in red blood cells, is approximately 5 nanometers in diameter. Nanoscale devices smaller than 50 nanometers can easily enter most cells, whi

Steganography works by replacing bits of useless or unused data in regular computer files (such as graphics, sound, text, HTML, or even floppy disks ) with bits of different, invisible information. This hidden information can be plain text, cipher text, or even images. Steganography sometimes is used when encryption is not permitted. Or, more commonly, steganography is used to supplement encryp

Background of Internet ProtocolsIn the mid-1970s, the Defense Advanced Research Projects Agency (DARPA) became interested inestablishing a packet-switched network to provide communications between research institutions inthe United States. DARPA and other government organizations understood the potential ofpacket-switched technology and were just beginning to face the problem virtually all compani

Tools define our culture. We aren't so much what we make as what we use to make it. Even barbarians can make holes with a bow and shaft; we have drill presses, hydraulic punches, and lasers. More importantly, the development of tools defines civilization. No culture is considered civilized unless it uses the latest tools. The PC is the tool that defines today's current age and culture. Once a tool
