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)
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)
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)
Cancer drug is no different in effectiveness as gold standard treatment for macular degeneration
Investigators from Boston University School of Medicine (BUSM) and the VA Boston Healthcare System have shown, at 6 months in a small group of patients, that there is no difference in efficacy between Bevacizumab (Avastin) and Ranibizumab (Lucentis) for the treatment of age-related macular degeneration (AMD). view more (2009-10-12)
Largest-ever collection of coins from Bar-Kokhba revolt found
The largest cache of rare coins ever found in a scientific excavation from the period of the Bar-Kokhba revolt of the Jews against the Romans has been discovered in a cave by researchers from the Hebrew University of Jerusalem and Bar-Ilan University. view more (2009-09-10)
Gold Solution for Enhancing Nanocrystal Electrical Conductance
In a development that holds much promise for the future of solar cells made from nanocrystals, and the use of solar energy to produce clean and renewable liquid transportation fuels, researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have reported a technique by which the electrical conductivity... view more...

Platinum nanocatalyst could aid drugmakers
Nanoparticles combining platinum and gold act as superefficient catalysts, but chemists have struggled to create them in an industrially useful form. view more (2009-09-01)
Hankering for molecular electronics? Grab the new NIST sandwich
The sandwich recipe recently concocted by scientists working at the National Institute of Standards and Technology (NIST) may prove tasty for computer chip designers, who have long had an appetite for molecule-sized electronic components - but no clear way to satisfy it until now. view more (2009-08-27)
New nanolaser key to future optical computers and technologies
Because the new device, called a "spaser," is the first of its kind to emit visible light, it represents a critical component for possible future technologies based on "nanophotonic" circuitry, said Vladimir Shalaev, the Robert and Anne Burnett Professor of Electrical and Computer Engineering at Purdue University. view more (2009-08-17)
UK Study Finds Meal Replacements Aid Weight Loss
Meal replacements in a medically supervised weight loss program are successful in facilitating weight loss, according to a new study conducted at the University of Kentucky. view more (2009-08-13)
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)
Researchers effectively treat tumors with use of nanotubes
By injecting man-made, microscopic tubes into tumors and heating them with a quick, 30-second zap of a laser, scientists have discovered a way to effectively kill kidney tumors in nearly 80 percent of mice. view more (2009-08-04)
One nano-step closer to weighing a single atom
By studying gold nanoparticles with highly uniform sizes and shapes, scientists now understand how they lose energy, a key step towards producing nanoscale detectors for weighing any single atom. view more (2009-07-28)
All-in-one nanoparticle: A Swiss Army knife for nanomedicine
Nanoparticles are being developed to perform a wide range of medical uses -- imaging tumors, carrying drugs, delivering pulses of heat. Rather than settling for just one of these, researchers at the University of Washington have combined two nanoparticles in one tiny package. view more (2009-07-28)

Ultrasensitive detector promises improved treatment of viral respiratory infections
A Vanderbilt chemist and a biomedical engineer have teamed up to develop a respiratory virus detector that is sensitive enough to detect an infection at an early stage, takes only a few minutes to return a result and is simple enough to be performed in a pediatrician's office. view more (2009-06-29)
Nonstick and laser-safe gold aids laser trapping of biomolecules
Biophysicists long for an ideal material-something more structured and less sticky than a standard glass surface-to anchor and position individual biomolecules. view more (2009-06-18)
Newly discovered reactions from an old drug may lead to new antibiotics
A mineral found at health food stores could be the key to developing a new line of antibiotics for bacteria that commonly cause diarrhea, tooth decay and, in some severe cases, death. view more (2009-06-02)
