Bugs trained to build circuit

October 11, 2002

Researchers are developing bacteria to form nanoscale microbial machines that could eventually repair wounds or build microscopic electrical circuits.

Researchers at the Forestry and Forest Products Research Institute in Ibaraki, Japan trained the bacterium Acetobacter xylinum to exude ribbons of cellulose, a biological building material, laying down strips at a rate of 4,000ths of a millimetre per minute.

They are also exploring the use of genetically modified bacteria… read more

Taking a Clinical Look at Human Emotions

October 9, 2002

Previously, brain studies tended to bypass phenomena that are difficult to measure, like emotions and the unconscious. NYU prof. of neuroscience Dr. Joseph LeDoux, in his laboratory, began finding ways to study how the brain processes emotions.

Kurzweil to discuss radical life-extension and the Singularity at Alcor conference

September 30, 2002

Ray Kurzweil will present a comprehensive program for extending longevity and vitality that he devised in collaboration with longevity expert Terry Grossman, M.D. in “A Bridge to a Bridge to a Bridge,” a talk at the Fifth Alcor Conference on Extreme Life Extension in Newport Beach, CA, November 15-17. Based on correcting imbalances in metabolic processes, the program is the subject of a forthcoming book and is a… read more

Fifth Alcor Conference on Extreme Life Extension to profile cryonic breakthroughs

September 25, 2002

Cryonic breakthroughs in preventing tissue damage from freezing, human therapeutic cloning to replace damaged or missing tissue, and radical new techniques for life extension will be among the topics addressed at the Fifth Alcor Conference on Extreme Life Extension in Newport Beach, CA, November 15-17.Michael D. West, President & CEO of Advanced Cell Technology; Ray Kurzweil, CEO, Kurzweil Technologies; and Gregory Benford, science fiction writer and Professor of… read more

Out-of-body experience clues may hide in mind

September 20, 2002

Swiss neurology researchers have tied “out the body experience” to stimulation the brain’s angular gyrus in the right cortex. This part of the brain is responsible for things like body and space awareness, and logical sequencing.

Controlling Robots with the Mind

September 19, 2002

People with nerve or limb injuries may one day be able to command wheelchairs, prosthetics and even paralyzed arms and legs by “thinking them through” the motions.

Scientists have developed implantable microchips that will embed the neuronal pattern recognition now done with software, thereby eventually freeing the brain-machine interface devices from a computer. These microchips will send wireless control data to robotic actuators.

Forever Young: The new scientific search for immortality

August 29, 2002

Researchers are making a lot of progress in extending life span. Techniques being developed include calorie restriction, therapeutic cloning, genetic research for the longevity gene, anti-oxidants, getting cells to produce telomerase, hormone replacement therapies, genetic engineering, and nanomedicine.
