The plan is to build a “sub-critical” nuclear reactor. Such a reactor would not be able to sustain a chain reaction. Instead, the nucleus-transmuting subatomic particles would be supplied from outside, using a particle accelerator.Facilities, which will probably cost around $1 billion each, are being planned by physicists in Japan and Europe to come on …
The DNA origami steps are described In Rothemund’s method, a long strand of DNA snakes back and forth until it forms a desired shape. The key to getting the DNA to form this way, and to holding it in place, are short “staples” of DNA with sequences chosen to attach to specific parts of the …
James Baker designs nanoparticles to guide drugs directly into cancer cells, which could lead to far safer treatments. Cancer therapies may be the first nanomedicines to take off. Treatments that deliver drugs to the neighborhood of cancer cells in nanoscale capsules have recently become available for breast and ovarian cancers and for Kaposi’s sarcoma. The …
Another example that new more precise tools can help reveal important details of problems such as disease. Diffusion tensor imaging (DTI) a variation of magnetic resonance imaging (MRI) that allows the study of the connections between different brain areas. Conventional imaging techniques, such as structural MRI, reveal major anatomical features of the brain — gray …
Nanomaterial tools are being applied to medicine. Medical researchers have long known that diseases can cause — or be caused by — physical changes in individual cells. For instance, invading parasites can distort or degrade blood cells, and heart failure can occur as muscle cells lose their ability to contract in the wake of a …
ABI research discusses new real time traffic systems including dedicated short range communication DSRC is a two-way network that sends more data about the vehicle itself and road conditions to listening points along the highway. Advances beyond RFID can add more memory to record and track item location history. Research on the RFID market indicates …
There has been advance that allows the gathering of quantitative, real-time information on protein expression in living cells at the single-molecule level. This will allow a deeper understanding of the body and biology at the molecular level. Understanding at a real-time and molecularly precise level is useful to learn how to better control and utilize …
Cosmetic surgery statistics show 10.2 million cosmetic surgery procedures were performed in 2005 in the United States I interpret this to mean that people will be seeking out performance and appearance enhancement via gene therapy and other technology as it is available.
Scientists at the National Nano Fab Center at the Korea Advanced Institute of Science and Technology (KAIST) have developed the world’s smallest transistor, with a channel length of 3-nanometers, according to a Korea Herald report. The device is a three-dimensional FinFET. This will allow the development of terabit memories. It could allow conventional silicon integration …
Bone cells grown on carbon nanotubes Because carbon nanotubes are not biodegradable, they behave like an inert matrix on which cells can proliferate and deposit new living material, which becomes functional, normal bone, according to the paper. They therefore hold promise in the treatment of bone defects in humans associated with the removal of tumors, …
Impressive progress is being made towards DNA nanotechnology. A map of the Americas measuring just a few hundred nanometres across has been created out of meticulously folded strands of DNA, using a new technique for manipulating molecules dubbed “DNA origami”. More information is here The “DNA origami” procedure laid out by Paul Rothemund of the …
