‘Chasing Life’ chapter 1, part 2: ‘Beginning the chase’

March 28, 2007

In a new book, “Chasing Life,” CNN Chief Medical Correspondent Dr. Sanjay Gupta travels the world to find methods of improving health and longevity, quoting Ray Kurzweil, who thinks scientific progress is advancing so quickly, we will all be able to live forever–if we can only make it a few more decades.

The world has gotten smaller and more accessible since applications like Google Earth became mainstream, says UC Santa Barbara Professor of Geography Michael Goodchild. There is still a long way to go, and there are important steps to take to get there.

Going local instead of global

“There’s no such thing as a true map,” said Goodchild, pointing out three versions… read more

Charmed by Six Feet of Circuitry

August 8, 2002

Grace, a six-foot autonomous robot, was the star of the recent annual meeting of the American Association for Artificial Intelligence in Canada.Grace performed successfully in the “Robot Challenge” event: start at the entrance to the conference center, take the elevator to the registration desk, register for the conference and then deliver a speech in the auditorium.

Grace was co-developed by Carnegie Mellon University (overall hardware and software architecture), the… read more

Charles Ostman discusses synthetic biology and the Singularity

February 6, 2008

“Historian of the future” Charles Ostman will discuss synthetic biology, junk DNA, the Singularity, and possible genetic modification of the human species from an external source on the nightly national CoastToCoast AM radio show on Wednesday February 6th.

Charles fears science could kill life on earth

May 5, 2003

Prince Charles fears that nanotech molecular assembly research could lead to the gray goo scenario. He’s organizing a crisis summit of leading scientists to address this concern.

Two innovations for on-the-go mobile-device users seeking a quick charge are in the works: Starbucks plans to install wireless charging devices in all of its stores; and a new battery design could enable rapid charging of lithium-ion batteries in ten minutes.

Starbucks stores will have “Powermat Spots” — designated areas on tables and counters where customers can place their compatible device and charge them wirelessly. The system uses… read more

Charging Batteries without Wires

November 15, 2006

MIT researchers have worked out a theoretical scheme for a wireless-energy transfer that could charge or power devices within a couple of meters of a small power “base station” plugged into an electrical outlet.

The power base station would emit low-frequency electromagnetic radiation in the range of 4 to 10 megahertz. A receiver within a gadget–such as a power-harvesting circuit–could be designed to resonate at the same frequency emitted… read more

Engineers at the University of California, San Diego (UCSD) have discovered a method to increase the amount of electric charge that can be stored in graphene, a two-dimensional form of carbon, which could increase battery storage capacity.

The research, published in the journal Nano Letters, may provide a better understanding of how to improve the energy storage ability (energy density) of capacitors for potential uses… read more

Chaotic physics in ferroelectric materials may allow for brain-like computing

Unexpected behavior in ferroelectric materials explored by researchers at the Department of Energy’s Oak Ridge National Laboratory supports a new approach to information storage and processing called “memcomputing,” or memristor-based computing.

Ferroelectric materials are known for their ability to spontaneously switch polarization when an electric field is applied.

So using a scanning probe microscope, the ORNL-led team took advantage of… read more

Chaos filter helps robots make sense of the world

February 26, 2009

University of Oxford researchers have come up with a way for map-building robots to accurately recognize places they have been before, even when objects have moved or are approached from a new angle.

Their FabMap software tackles those problems by having a robot assign a visual “vocabulary” of up to a thousand individual “words” for each scene, every two seconds. That means when the robot revisits a scene that… read more

In 1963, Yale professor of physiology and psychiatry Dr. Jose Delgado implanted an stimulating electrode in the caudate nucleus of a fighting bull, bravely jumped into the bullring, and stopped the animal in its tracks by remotely activating the electrode. Now UMass Medical School scientists have taken neural control precision down to the synapse level, reversing a C. elegans (nematode) worm’s head position or locomotion direction by simply switching… read more
