{{| The nucleic acid-EFG molecule acts as a "guided missile," explained Prof. Levitzki, which, when injected into the blood stream, is avidly gobbled up by the multiple EGF receptors on the cancer cells, without harming normal cells. Once embedded in the tumor cells, it destroys them from within – a true "Trojan horse," said Prof. Levitzki. Normal cells, which possess 20 to100 less receptors for EGF, are spared, since the amount of double-stranded RNA gobbled up is insufficient to induce them to die. |}}

{{| A computer algorithm written by the researchers scanned nearly 3,000 genes. Statistical techniques were then used to investigate whether particular transcription factors correlated with genes that were differentially expressed (turned on or off) between nurse bees and foragers. |}}

{{| Thorsen's group is working toward integrating the pumps into a portable blood analysis device, which soldiers could carry onto the battlefield. If exposure to chemical or biological weapons were suspected, the device could automatically and rapidly test a miniscule blood sample, rather than sending a large sample to a lab and waiting for the results. The chips are so small and cheap to make that they could be designed to be disposable, Bazant said, or they could be made implantable. |}}

{{| Meller is using novel methods to decode the sequence of bases on a DNA strand at the molecular level. Using beams of electrons, Meller punches tiny holes in thin silicon films, then pulls strands of DNA through these "nanopores" using an electric current. Each base is identified by a florescent marker attached to it, which allows the researchers to record the sequence of bases as the strand emerges from the nanopore. Meller has devised a system of lasers and highly sensitive detectors which greatly increase the process' resolution. He is the only researcher in the world using this method, which he names "Opti-Pore." |}}

{{| "These DNA computers won't compete with silicon computing in terms of speed, but their advantage is that they can be used in fluids, such as a sample of blood or in the body, and make decisions at the level of a single cell," says the researcher, whose work is funded by the National Science Foundation. Her main collaborators in this study were Milan Stojanovic, of Columbia University, and Darko Stefanovic, of the University of New Mexico. |}}

{{|Unlike the classic description of proteins described in science textbooks, IUPs are not completely locked into rigid, 3-D shapes that determine their function in the cell. Instead, IUPs have varying amounts of flexibility within their sometimes spaghetti-like structures that is critical for function. |}}

{{|The power of optical mapping lies in its ability to reveal the size and large-scale structure of a genome. The method uses fluorescence microscopy to image individual DNA molecules that have been divided into orderly fragments by so-called restriction enzymes. |}}
