Engineers show nanotube circuits can be made en masse

July 7, 2008

Stanford electrical engineers have developed a method for making integrated circuit chips with the needed variety of logic gates on the scale and with the parallelism that the semiconductor industry must employ to make chips that are economical.

The Stanford-devised process involves growing nanotubes on a quartz wafer and then transferring them onto a silicon wafer patterned with metal electrodes. The nanotubes could then connect the electrodes to make… read more

Scientists discover largest structure in universe

October 27, 2003

Scientists have discovered the largest structure yet found in the universe, a “Great Wall” of galaxies 1.37 billion light-years long, according to an article in Science, Oct. 24, 2003.

This cosmic ribbon dwarfs anything seen before by more than 600 million light-years. The wall’s vastness pushes the limits of existing cosmological theories.

Tiny ear listens to hidden worlds

March 1, 2010

“Optical tweezers” used to measure the sounds created by microscopic organisms have been developed by scientists at Glasgow and Oxford Universities and at the National Institute of Medical Research.

They suspended very small glass or plastic beads in a beam of laser light to measure the movement of these beads as they are jostled by tiny objects, allowing for detection of piconewton (extremely weak) forces at molecular scales. The… read more

A projector the size of a sugar cube

September 13, 2006

No larger than a sugar cube, a video projector developed by researchers at the Fraunhofer Institute for Photonic Microsystems contains just a single mirror which can be rotated around two axes.

Blood pressure ‘link to dementia’

July 11, 2008

Two studies have linked high blood pressure and dementia risk.

Imperial College London researchers found that reducing blood pressure with drugs reduced dementia by 13%. Alzheimer’s Society researchers found that one type of dementia (vascular dementia) was six times more likely to develop in people who had high blood pressure in their 40s and 50s, probably caused by restricted bloodflow.

U.S. Risks Losing Global Leadership in Nanotech

August 20, 2010

The U.S. dominated the rest of the world in nanotech funding and new patents last year, as U.S. government funding, corporate spending, and VC investment in nanotech collectively reached $6.4 billion in 2009. But according to a new report from Lux Research, countries such as China and Russia launched new challenges to U.S. dominance in 2009, while smaller players such as Japan, Germany and South Korea surpassed the… read more

Gold ‘nano-bullets’ shoot down tumours

November 5, 2003

Gold “nano-bullets” — tiny silica particles plated with gold and heated with near-infrared light — could seek and destroy inoperable human cancers, researchers report in the Proceedings of the National Academy of Sciences.

“We believe that we should also be able to treat very small metastases, not detected yet,” said Jennifer West, who led the study at Rice University,

How to build a superluminal computer

March 9, 2010

Superluminal (faster-than-light) hypercomputers could be created by taking advantage of the nonlocal phenomenon (instant changes to a distant entangled particle), say Volkmar Putz and Karl Svozil at the Vienna University of Technology.

For example, light traveling through a vacuum can be made to spontaneously form into an electron-positron pair–an entangled pair–which then recombine to form a photon again. This process happens instantaneously, allowing the photon to effectively “jump” across… read more

Anthrax Dispute, Bioshield Woes

October 2, 2006

Project Bioshield, which promised to build national drug stockpiles to be used in case of a bioterror attack, has been put off until at least 2008 — and maybe later.

Strongest Material Ever Tested

In a strain measurement using perfect samples of graphene, Columbia University researchers have confirmed that is the strongest material ever tested.

The finding provides evidence that graphene transistors could be the most effective material to withstand heat in future ultrafast microprocessors.

Research Experiment Disrupts Internet, for Some

August 30, 2010

An experiment run by Duke University and a European group responsible for managing Internet resources went wrong Friday, disrupting a small percentage of Internet traffic.

The incident shows just how fragile one of the Internet’s core protocols really is, security experts say. The damage from Friday’s experiment was minimal, but if someone had been able to intentionally announce bad routes, it would have been much worse, said Paul Ferguson, a… read more

Defense research agency seeks to create supersoldiers

November 12, 2003

Maybe humans themselves need an upgrade, say DARPA thinkers. “The human is becoming the weakest link,” DARPA warned last year in an unclassified report. “Sustaining and augmenting human performance will have significant impact on Defense missions and systems.”

A review of the agency’s latest budget request reveals a host of projects aimed squarely at making soldiers smarter, tougher, faster, and stronger — zin short, superhuman.

Human arm transmits broadband

March 16, 2010

Researchers at Korea University in Seoul have demonstrated a prototype of a new biomonitoring system that transmits data through the body, replacing wires and minimizing the need for batteries.

In a test, they transmitted data at a rate of 10 megabits per second through a person’s arm, using a metal electrode coated with a flexible silicon-rich polymer.

The Korean team is working with a large electronics manufacturer to… read more

How mirror genes in ‘Junk DNA’ control brain processes, doubling the double helix

April 30, 2012

Mirror_miRNA

University of Bristol researchers have discovered a new group of molecules called called mirror-microRNAs that control some of the fundamental processes behind memory function and may hold the key to developing new therapies for treating neurodegenerative diseases.

MicroRNAs are non-coding genes that often reside within “junk DNA” and regulate the levels and functions of multiple target proteins that are responsible for controlling cellular processes in the brain. Two… read more
