UCR physicist demonstrates how light can be used to remotely operate micromachines
A research team led by Umar Mohideen, a physicist at the University of California, Riverside, has demonstrated in the laboratory that the Casimir force - the small attractive force that acts between two close parallel uncharged conducting plates - can be changed using a beam of light, making the remote operation of micromachines a possibility.   view more (2007-06-01)

Archaeologists rescue clues to ancient kingdom from the rising Nile
Archaeologists from the University of Chicago have discovered a gold processing center along the middle Nile, an installation that produced the precious metal sometime between 2000 and 1500 B.C. The center, along with a cemetery they discovered, documents extensive control by the first sub-Saharan kingdom, the kingdom of Kush.   view more (2007-06-19)

The gold standard: Biodesign Institute researchers use nanoparticles to make 3-D DNA nanotubes
Arizona State University researchers Hao Yan and Yan Liu imagine and assemble intricate structures on a scale almost unfathomably small. Their medium is the double-helical DNA molecule, a versatile building material offering near limitless construction potential.   view more (2009-01-05)

Humble shoelace tag carried more currency than gold on Columbus's travels
The humble device that prevents shoelaces from fraying was deemed to be worth more than gold by the indigenous Cubans who traded with Columbus's fleet.   view more (2006-10-04)

Swishing once a day with mouthrinse poses no harm to dental work
People have been paying more attention to the effects certain liquids like coffee, citrus-containing drinks, and even toothbrushes have on teeth. Mouthrinses are no exception.   view more (2007-01-12)

Turning green gunk to gold, anti-cancer gold
Combining synthetic chemistry techniques with a knowledge of the properties and actions of enzymes, scientists have been able to produce an exciting class of anti-cancer drugs originally isolated from blue-green algae.   view more (2007-01-10)

Tightly packed molecules lend unexpected strength to nanothin sheet of material
Scientists at the University of Chicago and Argonne National Laboratory have discovered the surprising strength of a sheet of nanoparticles that measures just 50 atoms in thickness.   view more (2007-07-23)

Using Life's Building Blocks to Control Nanoparticle Assembly
Using DNA, the molecule that carries life's genetic instructions, researchers at the U.S. Department of Energy's Brookhaven National Laboratory are studying how to control both the speed of nanoparticle assembly and the structure of its resulting nanoclusters.   view more (2007-08-23)

Proteomics on a chip
'Golden approach' human proteine classification Proteomics on a chip Knowledge of the human proteome may provide us with even more insight than knowledge of DNA. This 'protein blueprint' of a human contains valuable information about cell properties and disease causes. A single cell, however, already consists of several thousands of proteines. To... view more... (2002-06-18)

Multi-laboratory study sizes up nanoparticle sizing
As a result of a major inter-laboratory study, the standards body ASTM International has been able to update its guidelines for a commonly used technique for measuring the size of nanoparticles in solutions.   view more (2009-08-12)

Treating drug-addicted doctors is good medicine
Doctors who become addicted to alcohol and other drugs can be treated successfully and returned to medical practice with the help of special programs that couple referral to treatment and monitoring with rapid responses to noncompliance, University of Florida researchers report.   view more (2009-02-25)

New fuel cell catalyst uses 2 metals
Material scientists at Washington University in St. Louis have developed a technique for a bimetallic fuel cell catalyst that is efficient, robust and two to five times more effective than commercial catalysts.   view more (2009-05-15)

The end of the line for existing stem cell research?
Time is short for scientists to respond to the call for comments on the National Institutes of Health (NIH) proposed guidelines for the use of human embryonic stem (ES) cell lines and their eligibility for federal funds.   view more (2009-05-15)

An exquisite container
In campy old movies, Lucretia Borgia swans around emptying powder from her ring into wine glasses carelessly left unattended. The poison ring is usually a confection of gold filigree holding a cabochon or faceted gemstone that can be broken to empty the ring's contents. It is invariably enormous - so large it is rather odd nobody seems to notice... view more... (2009-11-02)

Micropatterned material surface controls cell orientation
Cells could be orientated in a controlled way on a micro-patterned surface based upon a delicate material technique, and the orientation could be semi-quantitatively described by some statistical parameters.   view more (2009-10-14)

Researchers Discover a Potential On-Off Switch for Nanoelectronics
As electronic circuits shrink from finely etched lines in silicon wafers to nearly elusive proportions, researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and Columbia University are studying how electrons flow through a molecular junction-a nanometer scale circuit element that contacts gold atoms... view more...

Nanoscale dimensioning is fast, cheap with new NIST optical technique
A novel technique under development at the National Institute of Standards and Technology (NIST) uses a relatively inexpensive optical microscope to quickly and cheaply analyze nanoscale dimensions with nanoscale measurement sensitivity.   view more (2008-10-30)

Ancient organisms discovered in Canadian gold mine
Scientists have suspected that the three known domains of life -- eukaryotes, bacteria, and archaea -- branched off and went their separate ways around three billion years ago. But pinning down the time of that split has been an elusive task.   view more (2007-08-21)

Smallest Nanoantennas for High-speed Data Networks
More than 120 years after the discovery of the electromagnetic character of radio waves by Heinrich Hertz, wireless data transmission dominates information technology.   view more (2009-10-21)

EARLY CASE OF RESISTANCE TO NEW ANTIBIOTIC (p 207)
A fast-track research letter published in this week’s issue of THE LANCET describes the case of a patient whose infecting bacterium developed resistance to one of the new so-called bug-busting antibiotics. Multidrug resistant bacteria have caused enormous difficulties worldwide over the past few decades. Scientists had hoped, however, that... view more... (2001-07-18)
