Transforming Nanowires Into Nano-Tools Using Cation Exchange Reactions
A team of engineers from the University of Pennsylvania has transformed simple nanowires into reconfigurable materials and circuits, demonstrating a novel, self-assembling method for chemically creating nanoscale structures that are not possible to grow or obtain otherwise. view more (2009-10-26)
Berkeley Researchers Find New Route to Nano Self-Assembly
If the promise of nanotechnology is to be fulfilled, nanoparticles will have to be able to make something of themselves. An important advance towards this goal has been achieved by researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) who have found a simple and yet powerfully robust way to induce... view more...

Scientists visualize assembly line gears in ribosomes, cell's protein factory
Even as research on the ribosome, one of the cell's most basic machines, is recognized with a Nobel Prize, scientists continue to achieve new insights on the way ribosomes work. view more (2009-10-16)
U-M physicists create first atomic-scale map of quantum dots
University of Michigan physicists have created the first atomic-scale maps of quantum dots, a major step toward the goal of producing "designer dots" that can be tailored for specific applications. view more (2009-09-30)
Largest ever Alzheimer's gene study unveils dementia mysteries
The results, from the largest ever Alzheimer's genome-wide association study (GWAS) involving 16,000 individuals, are published in Nature Genetics. They are the first new genes found to be associated with the common form of Alzheimer's disease since 1993. view more (2009-09-08)
Surface features on Titan form like Earth's, but with a frigid twist
"It is really surprising how closely Titan's surface resembles Earth's," says Rosaly Lopes, a planetary geologist at the Jet Propulsion Laboratory (JPL) in Pasadena, California, who is presenting the results on Friday, 7 August. view more (2009-08-07)
New insight into human ciliopathy
In the September 1st issue of G&D, Dr. Karen Oegema (UCSD) and colleagues identify the molecular basis of the lethal developmental disorder, hydrolethalus syndrome, and reveal that hydrolethalus syndrome actually belongs to the emerging class of human ciliopathy diseases. view more (2009-08-04)
Mapping the crocodile genome
The first ever genetic linkage map for a non-avian member of the Class Reptilia has been developed. Researchers writing in the open access journal BMC Genomics have constructed a first-generation genetic linkage map for the saltwater crocodile Crocodylus porosus. view more (2009-07-29)
'Artificial Golgi' may provide new insight into key cell structure
Scientists in New York and North Carolina are reporting assembly of the first functioning prototype of an artificial Golgi organelle. view more (2009-07-29)
Fighting disease atom by atom
Researchers at Rice University and their international colleagues have for the first time described the atomic structure of the protein shell that carries the genetic code of hepatitis E (HEV). view more (2009-07-22)
Building memories with actin
Memories aren't made of actin filaments. But their assembly is crucial for long-term potentiation (LTP), an increase in synapse sensitivity that researchers think helps to lay down memories. view more (2009-07-13)
Spontaneous Assembly: A New Look at How Proteins Assemble and Organize Themselves into Complex Patterns
Self-assembling and self-organizing systems are the Holy Grails of nanotechnology, but nature has been producing such systems for millions of years. view more (2009-07-09)
Double success for Instituto Gulbenkian de Ciencia scientists working on chromosome segregation
Lars Jansen's work on the formation of the centromere, a key cellular structure in powering and controlling chromosome segregation and accurate cell division, has just earned him a paper in Nature Cell Biology and a prestigious EMBO installation grant, of 50,000 euro per year, for a maximum of five years. view more (2009-07-01)
New electron microscopy images reveal the assembly of HIV
Scientists at the European Molecular Biology Laboratory (EMBL) and the University Clinic Heidelberg, Germany, have produced a three-dimensional reconstruction of HIV (Human Immunodeficiency Virus), which shows the structure of the immature form of the virus at unprecedented detail. view more (2009-06-23)
New study reveals structure of the HIV protein shell
New research by scientists at The Scripps Research Institute and other institutions provides a close-up look at the cone-shaped shell that is the hallmark of human immunodeficiency virus (HIV), revealing how it is held together-and possible ways to break it apart. view more (2009-06-15)
Penn materials scientist finds plumber's wonderland on graphene
Engineers from the University of Pennsylvania, Sandia National Laboratories and Rice University have demonstrated the formation of interconnected carbon nanostructures on graphene substrate in a simple assembly process that involves heating few-layer graphene sheets to sublimation using electric current that may eventually lead to a new paradigm... view more...
