Studying potential health and environmental effects of tiny industrial building blocks, called nanoparticles, is the goal of a $389,303 grant from the U.S. Environmental Protection Agency (EPA) to Vicki Grassian, director of the University of Iowa Nanoscience and Nanotechnology Institute.
Theoretical physicists from Argonne National Laboratory, US, and RIKEN's Advanced Science Institute, Wako, have constructed a general theory for describing the characteristics of an unusual and newly discovered system of particles, a chain of 'spin-1/2 bosons'.
MIT engineers are using carbon nanotubes only billionths of a meter thick to stitch together aerospace materials in work that could make airplane skins and other products some 10 times stronger at a nominal increase in cost.
Research into RNA, a molecule found in every cell of our bodies, could lead to remarkable advances in the treatment of diseases such as cancer and diabetes, a meeting organised by the European Science Foundation was told.
Mauro Ferrari, Ph.D., a nanomedicine scientist at The University of Texas Health Science Center at Houston and The University of Texas M. D. Anderson Cancer Center, has received a five-year, $7 million Innovator Award from the U.S. Department of Defense (DoD) Breast Cancer Research Program to develop a targeted new delivery system for breast cancer drugs.
Optical technology developed by a Northwestern University professor of biomedical engineering has been shown to be effective in detecting the presence of pancreatic cancer through analysis of neighboring tissue in the duodenum.
In quantum mechanics, a vanguard of physics where science often merges into philosophy, much of our understanding is based on conjecture and probabilities, but a group of researchers in Japan has moved one of the fundamental paradoxes in quantum mechanics into the lab for experimentation and observed some of the 'spooky action of quantum mechanics' directly.
In order for the potential health risks associated with nanotechnology to be properly assessed, the current regulatory system in the US must be changed. That is the conclusion of a new paper, published in the peer-reviewed journal Environmental Science and Technology.
New research findings reveal the electrical resistance through molecular junctions can be turned 'on' and 'off' simply by pushing and pulling the junction - a feature that could be used as a switch in nanoscale electronic devices.
Just as x-ray technology, MRI and sonography transformed the practice of medicine, a newly created approach for seeing the invisible promises great potential for finding new ways to improve the health of human and microelectronic patients alike.
Researchers in Japan have developed a new method for producing ultra-lightweight hollow carbon fine particles (diameters ranging from several nanometers to several tens of micrometers) from lignin, which is a byproduct obtained in large quantities during the manufacture of paper or bio-ethanol, and inorganic salts.
