Synapse chip taps into brain chemistry

March 26, 2003

Stanford University researchers have developed “artificial synapses” on a silicon chip.

When an electric field is applied, the neurotransmitter is pumped through an internal pipeline, and a little of it squeezes out of the hole, stimulating nearby neural cells.

This could open the way to neural prosthetic implants that combine chemical and electrical stimulation in one implant. These could interact with cells in more subtle and precise ways.… read more

The Age of Robots might finally have arrived. Robots are doing real jobs alongside humans — in homes, hospitals and on the battlefield

Spider silk delivers finest optical fibers

March 24, 2003

Delicate threads of spider’s silk are about to solve a major problem in photonics: how to make hollow optical fibres narrow enough — just two nanometers wide — to carry light beams around the fastest nanoscale optical circuits.

They will also make for a new breed of sensors that can detect single molecules of a particular chemical.

Undercover genes slip into the brain

March 24, 2003

A molecular Trojan horse that can slip past the brain’s defences has proved to be very effective at delivering genes, drugs and other compounds to the brains of primates. It could be used to treat a host of brain disorders, from Parkinson’s to epilepsy.

Recent advances in computer vision

March 24, 2003

Human eye movements to scroll a computer screen up and down, a camera that periodically scans a scene in front of you and turns images into sounds, automatic media interpretation to assist users in searching for specific scenes and shots, and a system that can detect suspicious pedestrian behavior in parking lots are examples of new computer-vision systems.

Alternate Reality Games Grab Mindshare

March 17, 2003

ARGs or Alternate Reality Games are immersive experiences that mix real world clues, phone calls, voicemail, email chatterbots, real people playing roles in real life and bogus and legit websites. The objective: a fully rounded gaming experience that bleeds over into everyday life. They could also have real-world applications like group dynamics and problem solving.
