H.P. Sees a Revolution in Memory Chip

April 8, 2010

Hewlett-Packard scientists plan today to report advances in the design of memristors, a new class of devices capable of replacing transistors, using a vast three-dimensional array, which allows for ultradense computing devices.

HP now has working 3-nanometer memristors that can switch on and off in about a nanosecond. HP says it could have a competitor to flash memory in three years that would have a capacity of 20 gigabytes… read more

New Google tool aims to provide more insight into online searches

August 7, 2008

Google has launched Google Insights for Search, an extension of Google Trends, designed to be used by advertisers, small business owners, academics and others.

Like Google Trends, the Insights software lets users type in search terms and then see search volume patterns over time and the top related and rising searches. But users can also now compare volume trends across multiple search terms, vertical industry categories, geographic regions and… read more

Nanomechanical memory demoed

November 22, 2004

A team at Boston University has made a minuscule mechanical memory cell from silicon. The device is a bistable compressed beam clamped at both ends.

The memory cell beam is 8,000 nanometers long by 300 nanometers wide by 200 nanometers high. It can be switched at 23.5 MHz. The cell’s size allows more than 100 gigabytes to be stored per square inch and uses several orders of magnitude less… read more

IBM plans self-aware computers

May 1, 2001

IBM has unveiled eLiza, an ambitious program to create computers that can maintain and update themselves automatically.

The name eLiza stands for “electronic lizard,” from the statement by futurist Ray Kurzweil that the IBM supercomputer Deep Blue (the chess computer that took on Gary Kasparov) was as smart as the average lizard.

A version of eLiza is being implemented on Blue Gene, the world’s fastest computer.

Maxed out: Testing humans to destruction

April 20, 2010

How far can you push the human body before it fails? New Scientist explores 12 extremes of endurance, from vacuum exposure to memory marathons, in a special feature.

Reprogramming brain cells to become heart cells

July 11, 2011

Protein Distribution

The direct conversion of a non-heart cell type into a heart cell by RNA transfer has been demonstrated by researchers at theĀ Perelman School of Medicine at the University of Pennsylvania.

The team first extracted mRNA from a heart cell, then put it into astrocytes or fibroblasts (brain cells). Because there were so many more heart-cell mRNAs versus astrocyte or fibroblast mRNAs, the heart-cell mRNAs took… read more

Spin flip trick points to fastest RAM yet

August 14, 2008

Researchers in Germany have built a Magnetoresistive random access memory (MRAM) system that is 10 times faster than existing MRAM systems.

MRAM is a faster and more energy efficient version of the RAM used in computers today, and hardware companies think it will in a few years dominate the market.

Why aging reduces immune system function

December 7, 2004

Oregon Health & Science University scientists have found that human T cell diversity fades with age, potentially resulting in a higher susceptibility to disease.

In old age the population of CD8 T cells — cells that recognize and destroy abnormal or infected cells and suppress the activity of other white blood cells to protect normal tissue — is dominated by less effective T cells. This results in an immune… read more

Sounds Of The Universe

May 22, 2001

Extraterrestrial acoustics and a “smart violin” attempt to clone the Stradivarius will be among the topics presented at the annual Acoustical Society of America conference, June 4-8, Palmer House Hilton Hotel, Chicago, Illinois.

New Way To Guide A Car: With Your Eyes, Not Hands

April 26, 2010

German researchers have developed a new technology, “eyeDriver,” that lets drivers steer cars going 31 mph (50 kph) using only their eyes.

Researchers link cocoa flavanols to improved brain blood flow

August 19, 2008

Cocoa flavanols, the unique compounds found naturally in cocoa, may increase blood flow to the brain, according to research by Harvard medical scientists.

Study participants who regularly drank a cocoa flavanol-rich beverage had an eight percent increase in brain blood flow after one week, and 10 percent increase after two weeks.

When the flow of blood to the brain slows over time, the result may be structural damage… read more

UAlbany College of Nanoscale Science and Engineering Awards First Ph.D. Degrees in Nanoscale Science

December 17, 2004

The world’s first Ph.D. degrees in nanoscience from a college devoted exclusively to the study of nanoscale scientific concepts were awarded to Drs. Spyridon Skordas and Wanxue Zeng at College of Nanoscale Science and Engineering (CNSE) of the University at Albany – State University of New York.

Skordas’s Ph.D. dissertation examined metal organic chemical vapor deposition of aluminum oxide ultra-thin films for advanced transistor applications. Zeng explored plasma- assisted… read more

Molecular computer memory developed

June 11, 2001

A RAM memory prototype using organic molecular switches has been developed by researchers at Yale University. An array of molecules between two gold electrodes is used to store a 1 or 0 by applying a voltage pulse to the electrodes, causing the molecules to be kicked into another state in which their electrons are arranged differently, resulting in higher or lower conductivity.

Currently, 1000 molecules are used… read more

Army of smartphone chips could emulate the human brain

May 4, 2010

Steve Furber, a professor of computer engineering at the University of Manchester, is attempting to model the synaptic weights and coordinated voltage spikes of the human brain in a 1-billion-neuron silicon brain system called Spinnaker (Spiking Neural Network Architecture).

The chips, under construction in Taiwan, contain 20 ARM processor cores, each modelling 1000 neurons. With 20,000 neurons per chip, 50,000 chips will be needed to reach the target of… read more

Stelarc: Pushing the body’s boundaries

July 26, 2011

Stelarc is a performance artist who explores the capabilities of the human body.

“All of my projects explore alternate anatomical architectures — a body with a third hand, or an extra ear, or an artwork inside a bodily space instead of a public space,” he says. “We are biological bodies, but we are often accelerated, augmented, and enhanced by technology. There may be a time soon when… read more
