nanoscale technology: Artificial muscle advance

Researchers at the University of Dallas have created alcohol- and hydrogen-powered artificial muscles that are 100 times stronger than natural muscles, able to do 100 times greater work per cycle and produce, at reduced strengths, larger contractions than natural muscles. Among other possibilities, these muscles could enable fuel-powered artificial limbs, “smart skins” and morphing structures …

Another prediction appears closer to happening: Success in getting rid of nuclear waste

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 …

DNA nanotechnology: Follow up on DNA Origami breakthrough

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 …

State of nanoscale medicine

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 …

other tech: Diffusion Tensor Imaging on the path to more detailed brain scans

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 …

Nanobiomechanics

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 …

Beyond RFID: Dedicated Short Range Communication

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 …

Improving tools and imaging capability

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 …

other tech: 3 nanometer channel length transistor

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 …

Towards nanomedicine: Bone Cell grown on carbon nanotubes

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, …
