Researchers from the National Institute of Standards and Technology (NIST) have joined with an international team to engineer and measure a potentially important new class of nanostructured materials for microwave and advanced communication devices. Based on NIST's measurements, the new materials—a family of multilayered crystalline sandwiches—might enable a whole new class of compact, high-performance, high-efficiency components for devices such as cellular phones.

Recent advances in graphene research provide various possibilities to enhance performance characteristics and current approaches to design new bio-devices. Especially, smart and flexible bioelectronics on graphene has emerged as a new frontier in this area. Graphene has started to be seen an ideal signal transducer and promising alternative for the production of low cost bioelectronics devices. However, control and regulation on biological systems are always desired for advance applications and productions. The integration of biomolecules with electronic elements to fabricate functional devices attracts considerable attention because of the basic fundamental scientific questions and the potential applications of the system.

After suffering a traumatic brain injury, patients are often placed in a coma to give the brain time to heal and allow dangerous swelling to dissipate. These comas, which are induced with anesthesia drugs, can last for days. During that time, nurses must closely monitor patients to make sure their brains are at the right level of sedation — a process that MIT’s Emery Brown describes as “totally inefficient.”

DNA encodes the genetic material passed on from generation to generation. For the information encoded in the DNA to be made into the proteins and enzymes necessary for life, ribonucleic acid (RNA), single-stranded genetic material found in the ribosomes of cells, serves as intermediary. Although usually single-stranded, some RNA sequences have the ability to form a double helix, much like DNA.
