Samsung to release ’3D’ memory modules with 50% greater density

December 8, 2010

Samsung today announced a new 8GB dual inline memory module (DIMM) that stacks memory chips on top of each other using through silicon via (TSV), which increases the density of the memory by 50% compared to conventional DIMM technology.

Using the TSV technology will greatly improve chip density in next-generation server systems, Samsung said, making it attractive for high-density, high-performance systems. The TSV technology creates micron-sized holes… read more

Scientists Bringing ‘Table Top’ Particle Accelerators a Step Closer

September 30, 2004

Three research teams announced new developments in producing relativistic electron beams using laser-produced plasmas to accelerate the beams.

The beams have a narrow energy spread and are focusable. These new developments could help to shrink the size and cost of future particle accelerators for fundamental physics experiments and applications in materials and biomedicine. Laser electron accelerators could eventually fit into a university basement.

All three research teams published… read more

Automation of Nanotechnology Manufacturing May Be Ahead

August 2, 2007

Duke University engineers have adapted a computer aided design and manufacturing process to reproduce nanoscale structures with features sized on the order of single molecules.

The technology allows for repetitive engineering surface features at the nanoscale, and extends the typical 2-D nanopatterning schema into the third dimension. The system used atomic force microscopes to reliably produce 3-D, nanometer-scale silicon oxide nanostructures through a process called anodization nanolithography, in which… read more

Long, Stretchy Carbon Nanotubes Could Make Space Elevators Possible

January 26, 2009

Scientists from Cambridge University have developed a light, flexible, and strong type of carbon nanotube material that may bring space elevators closer to reality.

NASA needs about 144,000 miles of nanotube to build one, with a cable that would extend 22,000 miles above the Earth to a station.

Currently, the Cambridge team can make about 1 gram of the new carbon material per day, which can stretch to… read more

New Method Identifies Chromosome Changes in Malignant Cells

October 13, 2004

Princeton scientists have invented a fast and reliable method for identifying alterations to chromosomes that occur when cells become malignant. It quickly analyzes an entire genome and produces a reliable list of chromosome sections that have been either deleted or added.

The technique helps to show how cells modify their own genetic makeup and may allow cancer treatments to be tailored more precisely to a patient’s disease.… read more

Functioning Neurons Produced From Human Embryonic Stem Cells

August 10, 2007

Scientists with the Institute of Stem Cell Biology and Medicine at UCLA produced a highly pure, large quantity of functioning neurons from human embryonic stem cells. This will allow them to create models of and study diseases such as Alzheimer’s, Parkinson’s, prefrontal dementia and schizophrenia.

Researchers previously had been able to produce neurons from human embryonic stem cells. However, the percentage of neurons in the cell culture was not… read more

India’s $10 Laptop to be revealed Feb. 3

February 2, 2009

The Indian government has developed a prototype of the Rs 500, a $10 laptop with 2 GB of memory, WiFi, Ethernet, expandable memory, and consuming 2 watts of power.

Mice do fine without ‘junk DNA’

October 21, 2004

Mice born without large portions of their “junk DNA” seem to survive normally. The result contradicts the beliefs of many scientists who have sought to uncover the function of these parts of the genome.

David Haussler of the University of California, Santa Cruz, who has investigated why genetic regions are conserved, believes that non-coding regions may have an effect too subtle to be picked up in the tests to… read more

64-core chip promises to be a big leap ahead

August 20, 2007

Tilera Corp. is pioneering a new chip architecture based on MIT research and has begun to ship a 64-core processor, promising dramatic advances in powering devices for the networking and multimedia industries.

Tilera claims they will deliver more than 10 times the performance of current dual-core processors and 40 times the performance of today’s digital signal processors, and can be scaled to much larger grids.

Genetic roots of synaesthesia unearthed

February 6, 2009

The regions of our DNA that wire some people to “see” sounds have been discovered. So far, only the general regions within chromosomes have been identified, rather than specific genes, but the work could eventually lead to a genetic test to diagnose the condition before it interferes with a child’s education.

The Year in Web

December 29, 2010

Secrets are flying online, both state and personal, and Internet companies are still looking for ways to make money on applications—or with users’ private data.

CBEN launches partnership for sustainable nanotechnology

October 29, 2004

Rice University’s Center for Biological and Environmental Nanotechnology (CBEN) today announced the formation of the International Council on Nanotechnology (ICON), a collaboration among academic, industry, regulatory and non-governmental interest groups that will work to assess, communicate, and reduce potential environmental and health risks associated with nanotechnology.

Mind Over Matter, With a Machine’s Help

August 27, 2007

A number of new companies are commercializing real-time functional magnetic resonance imaging (fMRI).

Omneuron uses fMRI to treat chronic pain. The patient watches a computer-generated flame projected on the screen of virtual-reality goggles; the flame’s intensity reflects the neural activity of regions of the brain involved in the perception of pain. Using a variety of mental techniques — for instance, imagining that a painful area is being flooded with… read more

NEMS: Machines Get Tiny

March 22, 2001

The next frontier in machine miniaturization is nanoelectromechanical systems (NEMS).

The devices could be used as ultrasensitive sensors that can detect subtle genetic alterations responsible for a disease or artificial muscles that might replace damaged human tissue. The could also power tiny robots.
