NRL researchers develop optical technique for controlling electron spins in quantum dot ensembles
Scientists are closer to developing novel devices for optics-based quantum computing and quantum information processing, as a result of a breakthrough in understanding how to make all the spins in an ensemble of quantum dots identical. view more (2007-11-16)
Patient' exposure to radiation significantly lower when using new cardiac CT technique
A new cardiac CT technique, prospective gated 64-channel cardiac CT, has a significantly lower radiation dose and produces CT coronary angiograms with better image quality when compared with the standard retrospective ECG gating. view more (2008-04-14)
Debut of TEAM 0.5, the World's Best Microscope
TEAM 0.5, the world's most powerful transmission electron microscope - capable of producing images with half‑angstrom resolution (half a ten-billionth of a meter), less than the diameter of a single hydrogen atom - has been installed at the Department of Energy's National Center for Electron Microscopy (NCEM) at Lawrence Berkeley... view more...

Light turns liquid
LIGHT can be turned into a glowing stream of liquid that splits into droplets and splatters off surfaces just like water. The researchers who`ve worked out how to do this say "liquid light" would be the ideal lifeblood for optical computing, where chips send light around optical "circuits" to process data. Liquid light sounds like a... view more... (2002-07-03)
Disorder may be in order for 'spintronic' devices
Physicists at JILA are using ultrashort pulses of laser light to reveal precisely why some electrons, like ballet dancers, hold their spin positions better than others—work that may help improve spintronic devices, which exploit the magnetism or "spin" of electrons in addition to or instead of their charge. One thing spinning... view more... (2007-02-16)
Memory in artificial atoms
Three of our nano-physicists have made a discovery that can change the way we store data on our computers. This means that in the future we can store data much faster, and more accurate. Their discovery has been published in the scientific journal Nature Physics. view more (2008-04-08)
New design for transistors powered by single electrons
Scientists have demonstrated the first reproducible, controllable silicon transistors that are turned on and off by the motion of individual electrons. view more (2006-02-03)
The closest look ever at native human tissue
Seeing proteins in their natural environment and interactions inside cells has been a long-standing goal. Using an advanced microscopy technique called cryo-electron tomography, researchers from the European Molecular Biology Laboratory [EMBL] have visualised proteins responsible for cell-cell contacts for the first time. view more (2007-12-06)
McMaster University unveils world's most advanced microscope
The most advanced and powerful electron microscope on the planet-capable of unprecedented resolution-has been installed in the new Canadian Centre for Electron Microscopy at McMaster University. view more (2008-10-21)
Optical fibers monitor particle accelerator
The DESY laboratory in Hamburg is planning to build a 33-km linear collider. In order to fine-tune the beam to the equipment, scientists must determine the size and location of any radiation leaks. A newly developed fiber-optic measuring technique provides the answer. Living cells are small and the processes taking place inside them fast.... view more... (2002-02-01)
Nanoscale imaging reveals unexpected behaviors in high-temperature superconductors
Recent discoveries regarding the physics of ceramic superconductors may help improve scientists' understanding of resistance-free electrical power. view more (2007-05-31)
Atoms looser than expected
All the atoms in the universe just got looser, at least in the eyes of humans. No, the laws of physics didn't change overnight, but our knowledge of how strong atoms are held together did have to be readjusted a bit in light of a new experiment conducted at Harvard University. view more (2006-08-16)
Looking at neurons from all sides
A new technique that marries a fast-moving laser beam with a special microscope that look at tissues in different optical planes will enable scientists to get a three-dimensional view of neurons or nerve cells as they interact, said Baylor College of Medicine scientists in a report that appears today in the journal Nature Neuroscience. view more (2008-04-28)
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)
Carbon molecule with a charge could be tomorrow's semiconductor
Virginia Tech chemistry Professor Harry Dorn has developed a new area of fullerene chemistry that may be the backbone for development of molecular semiconductors and quantum computing applications. view more (2008-09-09)
Detailed echoes from inside the body
In the early days of medical ultrasound, physicians only saw shadowy outlines of the structures inside the body. Today's techniques are not only capable of providing still and moving images of very high resolution. They can be used to measure the rate of blood flow or even discern signs of hardening of the arteries: Where the walls of the blood... view more... (2003-03-11)
Aluminum-oxide nanopore beats other materials for DNA analysis
Fast and affordable genome sequencing has moved a step closer with a new solid-state nanopore sensor being developed by researchers at the University of Illinois. view more (2009-06-03)
Nowhere to hide -- new ultra-powerful microscope probes atomic world
A unique electron microscope, the first of its kind in the world, was unveiled yesterday at the STFC Daresbury Laboratory in Warrington. view more (2008-01-25)
World`s most powerful laser used as atom smasher - The Physics Congress 2002
Physicists at Glasgow University are using the world`s most powerful laser beam as an atom smasher to simulate conditions inside the Sun and to produce radioisotopes vital in medicine. Professor Ken Ledingham from the Department of Physics at Glasgow and his colleagues from Imperial College and the Rutherford Appleton Laboratory (RAL) are using... view more... (2002-03-26)
Why Nanolayers Buckle when Microbeams Bend
High-strength, ultra-light and elastic carbon materials are commonly used in high-performance sports goods and modern aerospace technology-for example in tennis rackets, racing tyres, heat shields and even guitars. view more (2005-12-16)
