Hewlett-Packard is researching molecular computers, using rotaxanes.
UCLA professor James Heath and his team have succeeded in attaching their minuscule switches to tiny wires and have developed a redundant wiring technique that routes signals around imperfect molecular switches.
Heath thinks he might be able to build a rudimentary computer within a couple of years.

A cybernetic definition of “life” has been proposed by Bernard Korzeniewski of the Institute of Molecular Biology at Jagiellonian University in Kraków, Poland: “A network of inferior negative feedbacks subordinated to a superior positive feedback.”
In other words, life is a system that tries to regulate itself to preserve its identity. Uner this definition, ants, prions, and infertile humans are not alive, but parasitic DNA is, he says.

The X (executable) Internet and an extended Net that connects to the real world will eclipse the Web, says Forrester Research.
“Executable applications will give users tools to experience the Net in more entertaining and engaging ways,” said Carl D. Howe, research director and principal analyst at Forrester. “For example, imagine a corporate buyer navigating a virtual marketplace with a Doom-like user interface — buyers could simply… read more

Sun’s new Project JXTA, using P2P networking, could benefit the AI community by combining the processing power of thousands of networked personal computers to create worldwide virtual supercomputers.
Headed by Bill Joy, Project JXTA (juxtapose) encourages “open source” development, with executable and source code for the initial implementation available in Java and C.

The sunlight-seeking Hyperion robot is about to be tested on Devon Island, near the Arctic Circle, mimicing a planetary landscape.
Developed by Carnegie Mellon University’s Robotics Institute in collaboration with the NASA Haughton-Mars Project, Hyperion is designed to dodge shadows, seek sunlight and drive itself along sun-synchronous routes, while carrying out exploration duties on Mars.
The National Institute for Standards and Technology (NIST) “Technology at the Crossroads: Frontiers of the Future” national meeting in Baltimore, Maryland is scheduled for June 3-5, 2001.
Sessions include Replication of Nanodevices, The Challenge of Molecular Electronics: Focusing Nanotechnology on the Future Computer, Virtual Voyage Through Medicine, The Pathway to Virtual Research Communities, Regenerative Medicine as Alternative Therapy, and Human Embryonic Stem Cells: Applications for Drug Discovery… read more

A wireless videoconferencing robot on wheels that allows telecommuters to hold real-time video chats with people in their office?
That’s what Sprint is planning with its Digitally Enhanced Network Appliance Project.

Aaron, an AI-based program that creates original paintings on your computer’s screen, has passed the art world’s Turing Test, says its creator, Harold Cohen, artist and University of California at San Diego art professor.
“Aaron’s output has been hung in major museums all around the world,” he said. “Since most of that happened before anybody was aware of how powerful the computer was, I have to assume… read more

Mapping common genetic diseases may turn out to be much easier. Segments of DNA shared by people with common ancestors can be much larger than previously thought — significantly decreasing the number of starting places researchers need to map genetic disorders.

American Museum of Natural History scientists are building a 21st century version of Noah’s Ark.
It will contain 70,000 tissue samples immersed in liquid nitrogen and will act as a central repository for nonhuman comparative genomics. It also may one day provide source material for creating clones of endangered or extinct animals.
