biotechnology summary

The fusion of flesh and machine is trend which, although inscribed in the history of modern technology from its beginnings, has reached a unprecedented momentum in recent years as a result of crucial advances in information technology, biology, and the development of global networks. Consequently, doubts are emerging concerning the viability of a distinct and definable human nature. Historical and social theories and concepts are being unhinged by the spread hybrids and by new forms of artificial life which are likely to trigger social changes escaping the grip of calculation. Attempts to defend an essential human nature against technical hybridisation, rather than strengthening the human subject, may have further blurred the question of historical subjectivity. Large amounts of money are invested into research and development of artifical biology, making some of the predictions of AI and robotics experts about radical and far reaching changes a matter of time.

Satellites

Communications satellites are relay stations for radio signals and provide reliable and distance-independent high-speed connections even at remote locations without high-bandwidth infrastructure.

On point-to-point transmission, the transmission method originally employed on, satellites face increasing competition from fiber optic cables, so point-to-multipoint transmission increasingly becomes the ruling satellite technology. Point-to-multipoint transmission enables the quick implementation of private networks consisting of very small aperture terminals (VSAT). Such networks are independent and make mobile access possible.

In the future, satellites will become stronger, cheaper and their orbits will be lower; their services might become as common as satellite TV is today.
