Nanotechnology provides 'green' path to environmentally sustainable economy
As products made with nanometer-scale materials and devices spread to more industries and markets, there is a growing opportunity and responsibility to leverage nanotechnology to reduce pollution, conserve resources and, ultimately, build a "clean" economy, advises a new report from the Project on Emerging Nanotechnologies. view more (2007-04-26)
Neuroscientists discover long-term potentiation in the olfactory bulb
Ben W. Strowbridge, Ph.D, associate professor of Neuroscience and Physiology/Biophysics, and Yuan Gao, a Ph.D. student in the neurosciences program at Case Western Reserve University School of Medicine, are the first to discover a form of synaptic memory in the olfactory bulb, the part of the brain that processes the sense of smell. view more (2009-05-04)
Tiny crystals promise big benefits for solar technologies
Los Alamos National Laboratory scientists have discovered that a phenomenon called carrier multiplication, in which semiconductor nanocrystals respond to photons by producing multiple electrons, is applicable to a broader array of materials that previously thought. view more (2006-01-05)
MIT researcher sees big impact of little cracks
An MIT researcher's atom-by-atom simulation of cracks forming and spreading may help explain how materials fail in nanoscale devices, airplanes and even in the Earth itself during a quake. view more (2006-01-19)
New nanocomposites may mean more durable tooth fillings
The mouth is a tough environment-which is why dentists do not give lifetime guarantees. Despite their best efforts, a filling may eventually crack under the stress of biting, chewing and teeth grinding, or secondary decay may develop where the filling binds to the tooth. view more (2007-04-30)
Purdue engineers solve chaos mystery in use of high-tech microscope
Mechanical engineers at Purdue University have proven that the same sort of "deterministic chaos" behind the baffling uncertainties of the stock market and long-term weather conditions also interferes with measurements taken with a commonly used scientific instrument. view more (2006-01-20)
UWE scientists find link between wilting plants and impotence
Researchers studying plant behaviour have discovered similarities between the processes preventing plants from wilting and humans from suffering impotence. Data recently published by the University of the West of England shows the same chemical chain of events is involved in both situations - and has led to an understanding of how water loss from... view more...

Brown researchers work toward ending cartilage loss
Scientists have long wrestled with how to aid those who suffer cartilage damage and loss. One popular way is to inject an artificial gel that can imitate cartilage's natural ability to act as the body's shock absorber. But that solution is temporary, requiring follow-up injections. view more (2008-06-04)
Caltech scientists create nanoscale zipper cavity that responds to single photons of light
Physicists at the California Institute of Technology (Caltech) have developed a nanoscale device that can be used for force detection, optical communication, and more. view more (2009-06-08)
New JILA apparatus measures fast nanoscale motions
A new nanoscale apparatus developed at JILA—a tiny gold beam whose 40 million vibrations per second are measured by hopping electrons—offers the potential for a 500-fold increase in the speed of scanning tunneling microscopes (STM), perhaps paving the way for scientists to watch atoms vibrate in high definition in real time. view more (2007-03-19)
Engineers point way to better use of nanotubes as measuring tips
Engineers at Purdue University have shown how researchers might better use tiny hollow fibers called "multi-walled carbon nanotubes" to more precisely measure structures and devices for electronics and other applications. view more (2005-10-13)
What do Racquel Welch and quantum physics have in common?
The study aims to delve into a 'void' or empty space in which atoms move, which has a large intrinsic energy density known as zero-point energy view more (2006-06-30)
UGA researchers achieve breakthrough in effort to develop tiny biological fuel cells
University of Georgia researchers have developed a successful way to grow molecular wire brushes that conduct electrical charges, a first step in developing biological fuel cells that could power pacemakers, cochlear implants and prosthetic limbs. The journal Chemical Science calls the technique "a significant breakthrough for... view more... (2009-06-22)
Sharply-tuned nanostrings work at room temperature
Using a fast, low-cost fabrication technique that allows inexpensive testing of a wide variety of materials, Cornell researchers have come up with nanoscale resonators - tiny vibrating strings - with the highest quality factor so far obtainable at room temperature for devices so small. view more (2006-07-17)
UCLA physicists create world's smallest incandescent lamp
In an effort to explore the boundary between thermodynamics and quantum mechanics - two fundamental yet seemingly incompatible theories of physics - a team from the UCLA Department of Physics and Astronomy has created the world's smallest incandescent lamp. view more (2009-05-07)
ORNL super water repellent could cause big wave in market
A water repellent developed by researchers at the Department of Energy's Oak Ridge National Laboratory outperforms nature at its best and could open a floodgate of commercial possibilities. view more (2007-11-30)
Smell of success for nanobiosensors
Modern-day doctors may soon start using smell to detect the early warning signs of different illnesses thanks to technology that replicates-and improves upon-the human olfactory system thanks to tiny bioelectronic sensors. view more (2006-05-15)
Oosight microscope enables embryonic stem cell breakthrough
A noninvasive, polarized light microscope invented at the Marine Biological Laboratory (MBL) played a crucial role in a recent breakthrough in embryonic stem-cell research aimed at developing medical therapies. view more (2007-11-30)
Finding by Rice University chemists could aid development of new nanodevices
Rice University chemists have discovered that tiny building blocks known as gold nanorods spontaneously assemble themselves into ring-like superstructures. view more (2007-03-12)
Molecular spintronic action confirmed in nanostructure
Researchers at the National Institute of Standards and Technology (NIST) have made the first confirmed "spintronic" device incorporating organic molecules, a potentially superior approach for innovative electronics that rely on the spin, and associated magnetic orientation, of electrons. view more (2006-10-13)
