New field of "strain engineering" could open up areas of materials research
In the ongoing search for new materials for fuel cells, batteries, photovoltaics, separation membranes, and electronic devices, one newer approach involves applying and managing stresses within known materials ...
Researchers use microRNA to trap mutant viruses in the lab
Genetic engineering alters mosquitoes' sense of smell
In one of the first successful attempts at genetically engineering mosquitoes, Howard Hughes Medical Institute (HHMI) researchers have altered the way the insects respond to odors, including the smell of humans ...
Portable nanodevice provides rapid, accurate diagnosis of tuberculosis, other bacterial infections
A handheld diagnostic device that Massachusetts General Hospital (MGH) investigators first developed to diagnose cancer has been adapted to rapidly diagnose tuberculosis (TB) and other important infectious ...
Piezoelectric 'taxel' arrays convert motion to electronic signals for tactile imaging
Using bundles of vertical zinc oxide nanowires, researchers have fabricated arrays of piezotronic transistors capable of converting mechanical motion directly into electronic controlling signals. The arrays ...
Optical magnetic microscope for high-resolution, wide-field cell imaging
Research brings new control over topological insulator
An international team of scientists investigating the electronic properties of ultra-thin films of new materials – topological insulators (TIs) - has demonstrated a new method to tune their unique properties using strain.
Researchers find key to controlling the electronic and magnetic properties of Mott thin films
"Mottronics" is a term seemingly destined to become familiar to aficionados of electronic gadgets. Named for the Nobel laureate Nevill Francis Mott, Mottronics involve materials – mostly metal oxides - ...
Research shows the success of a bacterial community depends on its shape
For some microbes, the motto for growth is not so much "every cell for itself," but rather, "all for one and one for all."
Sorting good bacteria from bad
An international team engineers and biologists has developed a new technique that could lead to improved infection diagnosis for cystic fibrosis patients.
New models predict where E. coli strains will thrive
Bioengineers at the University of California, San Diego have used the genomic sequences of 55 E. coli strains to reconstruct the metabolic repertoire for each strain. Surprisingly, these reconstructions do an excellent job of ...
Important mechanism behind nanoparticle reactivity discovered
An international team of researchers has used pioneering electron microscopy techniques to discover an important mechanism behind the reaction of metallic nanoparticles with the environment.
Hitchhiking virus confirms saga of ancient human migration
A study of the full genetic code of a common human virus offers a dramatic confirmation of the "out-of-Africa" pattern of human migration, which had previously been documented by anthropologists and studies of the human genome.
Biologists develop new method for discovering antibiotics
Biologists at the University of California, San Diego have developed a revolutionary new method for identifying and characterizing antibiotics, an advance that could lead to the discovery of new antibiotics to treat antibiotic ...
