Xerox Claims Printable Electronics Breakthrough

October 30, 2009

Xerox has announced a new silver ink that is apparently a breakthrough in printable electronics.

The possibilities range from printing on flexible plastic, paper and cardboard, and fabric, to printing RFID tags on almost anything.

Vitamin D deficiency may be linked to brain dysfunction

April 22, 2008

Scientists at Children’s Hospital & Research Center at Oakland have found evidence for vitamin D’s involvement in brain function, warranting vitamin D supplementation for groups chronically low in vitamin D, particularly nursing infants, the elderly, and African Americans.

The evidence includes wide distribution of vitamin D receptors throughout the brain and the vitamin’s ability to affect proteins in the brain known to be directly involved in learning and memory,… read more

Building a hand-held lab-on-a-chip to simplify blood tests

April 12, 2006

A cell phone-sized blood-count machine requiring less blood than a mosquito bite will make blood tests easier for many patients, from neonatal units to astronauts in space.

Probing Nanotech’s ‘Dark Side’

July 2, 2003

The U.S. Congress is on the verge of approving legislation that would require the government to examine the implications of nanotechnology as it pumps funds into the promising field. The U.K. government is also moving to probe nanotech’s promise and peril.

Moore’s Law: Beating The Noise Problem

November 9, 2009

It may be possible to improve computer memories by using noise to overcome the increase in noise as transistors become smaller, using stochastic resonance, researchers at the Instituto Tecnologico de Buenos Aires suggest.

Adult heart derived stem cells develop into heart muscle

April 24, 2008

University Medical Center Utrecht and Hubrecht Institute researchers have succeeded in taking stem cells from adult human hearts and growing them into large numbers of new heart muscle cells.

The stem cells were derived from material left over from open-heart operations, and grew into fully developed heart muscle cells that contract rhythmically, respond to electrical activity, and react to adrenaline.

The method results in identical cells that could… read more

Micro-pump to cool future computer chips

April 27, 2006

Purdue University engineers have developed a “micro-pump” cooling device small enough to fit on a computer chip that circulates coolant through channels etched into the chip.

“Our goal is to develop advanced cooling systems that are self-contained on chips and are capable of handling the more extreme heating in future chips,” said Suresh Garimella, director of Purdue’s Cooling Technologies Research Center.

The prototype chip contains numerous water-filled micro-channels,… read more

Robots learn to handle objects, understand new places

September 6, 2011

Robot Manipulation

Cornell’s Personal Robotics Laboratory computer scientists are teaching robots to manipulate objects and find their way around in new environments. They reported two examples of their work at the 2011 Robotics: Science and Systems Conference June 27 at the University of Southern California.

A common thread running through the research is “machine learning” — programming a computer to observe events and… read more

Accelerating-change conference announced

July 14, 2003

The Accelerating Change Conference (ACC2003): Exploring the Future of Accelerating Change, will be held at Stanford University, September 12-14, 2003.

ACC2003 speakers include Ray Kurzweil (via Teleportec’s 3D Telepresence Lectern); venture capitalist Steve Jurvetson of Draper Fisher Jurvetson; K. Eric Drexler, Founder and Chairman of Foresight Institute; Greg Papadopoulos, CTO of Sun Microsystems; Tim O’Reilly, CEO of O’Reilly & Associates; Howard Bloom, author of Global Brain; and… read more

Can personalized medicine fix healthcare?

November 15, 2009

“Healthcare is a trial and error industry…because the current pharma R&D model of blockbusters for broad patient groups is broken,” says Rita Lim-Wilby, Conference Director at PCI Pharma. “The solution is targeted therapeutics.”

That’s the premise of PCI Pharma’s “Advances Towards Personalized Medicine,” a one-day symposium, to be held at the Claremont Resort and Spa, Berkeley, California, on Thursday, November 19, 2009, featuring ten speakers from the University of… read more

Home Brew for the Car, Not the Beer Cup

April 28, 2008

E-Fuel Corporation is developing a home ethanol system, the E-Fuel 100 MicroFueler.

It will be about as large as a stackable washer-dryer, sell for $9,995, and ship before year-end.

Using sugar as its main fuel source, it could cost as little as a dollar a gallon to make ethanol, which would produce one-eighth the carbon of the same amount of gasoline.

Biggest map of universe reveals colossal structures

May 16, 2006

Giant structures stretching more than a billion light years across have been revealed by two new maps of the distribution of galaxies in the universe. The updated atlases lend more support to the idea that the universe is dominated by dark matter and dark energy.

Scientists Discover a New Way to Slow Speed of Light

July 21, 2003

Researchers say they have slowed light in specially treated crystals of alexandrite and at room temperature. This could lead to a new generation of components to build optical and quantum computers and more-efficient optical communications systems.

On Your Last Nerve: Researchers Advance Understanding of Stem Cells

November 20, 2009

North Carolina State University researchers have identified a gene, FoxJ1, that tells embryonic stem cells in the brain when to stop producing neurons.

The research could lead to new treatments to replace damaged or diseased brain tissue.

Turning hands and packages into displays

Are you ready for haptic "smart hands" and interactive displays on packages?
April 15, 2016

The device uses 'time-reversal' processing to send ultrasound waves through the hand. This technique is effectively like ripples in water but in reverse -- the waves become more targeted as they travel through the hand, ending at a precise point on the palm. (credit: Sri Subramanian / University of Sussex)

Imagine using your hand as an interactive touch-screen display. Sounds like science fiction, but Nokia Research Centre and the European Research Council have funded a study, led by the University of Sussex, to develop such a device, which could be used as a display for the next generation of smartwatches and other smart devices.

Called SkinHaptics, the device (still in the lab) sends ultrasonic pulses… read more
