Scientists at the Naval Research Laboratory (NRL) have recently demonstrated the ability to control the spin population of the individual quantum shell states of self-assembled indium arsenide (InAs) quantum dots (QDs). These results are significant in the understanding of QD behavior and scientists' ability to utilize QDs in active devices or for information processing.
An international team of scientists led by the University of Leeds has shed new light on the little-understood motor protein called dynein, thought to be involved in progressive neurological disorders such as motor neuro...
The Springer journal Analytical and Bioanalytical Chemistry (ABC) has chosen the chemist Wei Sun (26) as the recipient of its Best Paper Award 2008. Sun is the lead author of a paper in ABC on developing advanced tools for in vivo biological imaging. The award, including the 1,000 euro prize, was created by Springer to help exceptional young scientists establish their research careers.
A net with large holes won't catch small fish. Likewise, the microscopic fibers in the protective mucus coatings of the eyes, lungs, stomach or reproductive system naturally bundle together and allow the tiniest disease-causing bugs, allergens or pollutants to slip by. But Johns Hopkins researchers have discovered a way to chemically shrink the holes in the mucus layer's netting so that it will keep out more of the unwanted particles.
University of Utah physicists and chemists developed a new method that uses a mirror of tiny silver "nanoparticles" so microscopes can reveal the internal structure of nearly opaque biological materials like bone, tumor cells and the iridescent green scales of the so-called "photonic beetle."
Research shows that it is possible to produce copper about 4 times stronger than commercial material - and doing so while also having a ductile material. As the thermal and electrical conductivity are also good, the manu...
What is nanotechnology? How will it affect our lives? And, why should we care? These are just a few of the questions addressed in Talking Nano, a wide-ranging 6-DVD set that includes presentations by noted researchers, a museum educator, and, remarkably, two very talented jugglers.
Scientists at the Naval Research Laboratory (NRL) are partnering with industry to develop a sensor system for biomolecules that could make a significant contribution to a variety of fields such as healthcare, veterinary diagnostics, food safety, environmental testing, and national security. NRL has developed a highly sensitive, portable biosensor system called the compact Bead Array Sensor System.
The shapes of some of the tiniest cellular structures are coming into sharper focus at the Howard Hughes Medical Institute's Janelia Farm Research Campus, where scientists have developed a new imaging technology that produces the best three-dimensional resolution ever seen with an optical microscope.
These objects are all chiral - they cannot exactly superimpose their mirror image by translation or rotation. A common example of this is human hands - a right hand cannot superimpose itself into its mirror image, a left...
