Catching waves: Measuring self-assembly in action

By making careful observations of the growth of a layer of molecules as they gradually cover the surface of a small silicon rectangle, researchers from NIST and North Carolina State University have produced the first experimental verification of recently improved theoretical models of self-assembled systems.

1. Catching the wave -- Researchers measure very short laser pulses
   12-03-2006 · EurekAlert!
   Scientists have perfected a technique for very accurately measuring and controlling the electromagnetic waves within some of the shortest laser pulses ever made, says new research published today. Being able to fully understand and control these laser pulses represents an important step towards using them to track and manipulate electrons in leading-edge research at the sub-atomic level.

2. Area responsible for 'self-control' found in the human brain
   08-21-2007 · EurekAlert!
   The area of the brain responsible for self-control -- where the decision not to do something occurs after thinking about doing it -- is separate from the area associated with taking action, scientists say in the Aug. 22 issue of the Journal of Neuroscience.

3. Cancer drug works by overactivating cancer gene
   11-20-2007 · EurekAlert!
   University of Michigan researchers have discovered that bortezomib, a promising cancer drug, is able to strike a blow against melanoma tumor cells by revving up the action of a cancer-promoting gene. The results suggest a novel treatment strategy: push cancer cells into overdrive, so that they self-destruct. The laboratory-based findings may lead to ways to give bortezomib with reduced side effects.

6. Physicists exploit ultra-cold gases to measure ultra-small magnetic fields
   05-21-2007 · EurekAlert!
   UC Berkeley physicist Dan Stamper-Kurn and colleagues have captured a Bose Einstein condensate within a laser beam to made a device that maps magnetic fields more precisely than ever before. The magnetometer relies on the fact that the spins of atoms in the BEC precess in a magnetic field at a rate proportional to the field strength. Highly sensitive at low frequencies, the magnetometer may prove better than SQUIDs at measuring brain waves.

   03-25-2007 · EurekAlert!
   As a new wave of stem cell research continues, cardiologists are trying to tap into the self-renewing cells' life-saving potential. Scientists have performed the first US controlled, randomized Phase I clinical trial using a three-dimensional guided catheter system to deliver muscular stem cells to the heart. The study was presented today at the American College of Cardiology's Innovation in Intervention: i2 Summit in New Orleans.

   In a paper published in the Astronomical Journal, Dr. Xiaolei Zhang, of the Naval Research Laboratory, and Dr. Ronald J. Buta, of the University of Alabama, report that they have developed an accurate and widely-applicable method for characterizing density wave features in galaxies. These density waves appear as high-density regions in galaxies in the forms of spirals, bars and rings.

9. Safer shipping by predicting sand wave behavior
   07-12-2007 · EurekAlert!
   Dutch researcher Joris van den Berg has developed a mathematical model to predict the movement of sand waves. Sand waves are formed by an interaction between the tidal current and sand. They are larger than sand ripples on the beach but smaller than sandbanks. Sand waves largely determine the shape of the sea floor in the southern part of the North Sea. A good predictive computer model would be a valuable tool for shipping and designers of offshore infrastructures.

10. Unmasking DNA
    09-04-2007 · EurekAlert!
    A team of researchers at Young University propose the marriage of DNA self-assembly with standard microfabrication and lithography tools to form features such as nanochannels, nanowires and nanoscale trenches. This discovery may open up new avenues for nanofabrication at dimensions not accessible by conventional optical lithography.
