Detection of DNA on nanotubes offers new sensing, sequencing technologies

...'s Micro and Nanotechnology Laboratory. "This work opens possibilities for new types of nanotube-based sensing and sequencing technologies." In its natural state, DNA is in the double stranded form, consisting of two complementary strands, each resembling the side of a ladder and having a specific sequenc...

UW scientists unravel critical genetic puzzle for flu virus replication

...ic -- as opposed to a random -- method of assembly opens the door to the development of new antiviral drugs and the harnessing of benign influenza viruses as gene vectors to optimize vaccine production, Kawaoka says. "We need to have more antivirals for influenza," according to Kawaoka, "and as these segm...

Liver cancer linked to cellular repair pathway

... liver cancer, but not in mature liver cells, also opens the door for development of new diagnostic tests for the disease, Sicklick said. "Signs of excessive Hedgehog activity in cirrhotic patients could alert us to early stages of liver cancer, as well as provide valuable prognostic information for patien...

Living taste cells produced outside the body

...ime. The establishment of a viable long-term model opens a range of new opportunities to increase scientists' understanding of the sense of taste and how it functions in nutrition, health and disease. "We have an important new tool to help discover molecules that can enhance or block different kinds of ta...

Bioengineers create stable networks of blood vessels

... our understanding of the neuro-vascular niche and opens up ways to address repair of severed nerves," said Joseph Madri professor of pathology at Yale School of Medicine and a co-author. "We can now study what affects the attraction and repulsion of nerve growth and drug delivery in a model system that ca...

Yale scientists decipher 'wiring pattern' of cell signaling networks

...ins are in the proteome of an organism, this study opens the door to seeing how they are coordinated to work together. "This insight into the regulation and integration of biological networks has broad applications for basic science and clinical research," said Snyder. "Biological networks determine the d...

Carnegie Mellon U. transforms DNA microarrays with standard Internet communications tool

...in this system. "This new set of gene discoveries opens the way to new and more accurate models of the cell cycle system, which in turn can lead to new targets for cancer drugs," said Bar-Joseph. The new method also overcomes synchronization loss, a vexing problem for scientists who study hundreds or tho...

Worms know bad food when they smell it

...arning have been maintained through evolution, and opens the way for more in depth studies of how learning occurs. The study will be published in the November 10, 2005, issue of the journal Nature. One of C. elegans' fundamental behaviors is movement toward food based on its sense of smell. In the la...

MUHC investigators search for the root of sexual pain in women

... Professor of Psychology at McGill University. "It opens the door to new therapeutic possibilities including cognitive-behavioral pain management, physical therapy, surgery and alternate pain medication, which will hopefully result in fewer women suffering in silence." The new CIHR grant will allow the te...

Switching to new anti-bacterial targets: Riboswitches

... solved crystal structures of purine riboswitches, opens a path to the directed design of drugs targeting riboswitches for use as antibiotics. According to the researchers, it is inevitable that bacteria will evolve and that the drugs we use to cure bacterial infections will eventually become ineffective....

Synthetic Protein Eases Arthritis Symptoms in Mice

...nals that lead to arthritis symptoms. “This study opens a new research avenue to better understand and, perhaps, to treat rheumatoid arthritis, a condition that causes suffering in more than two million Americans,?says NIAID Director Anthony S. Fauci, M.D. Investigators from NIAID’s Laboratory of Immunol...

Zooming in on the protein-conducting channel

...bosome's protein synthesis machinery. The PCC then opens either a pore that is perpendicular or lateral to the cell membrane to feed the new protein either across or into the membrane. For the studies, the Swiss researchers created a complex comprising the PCC from E. coli attached to a ribosome that cont...

Membrane research opens window to benefits for plants, humans

...re of a water-protein channel -- an aquaporin that opens and closes a gate that regulates water movement in and out of cells. Not only was the discovery the first for a plant-water channel, it was the first plant-membrane channel for which an atomic resolution structure has been determined. "By recovering...

Scientists pinpoint inflammation gene

...covery of a new player in the inflammation pathway opens up many potential avenues for intervention on a broad range of health issues." Along with Blangero, lead researchers in identifying the SEPS1 (Selenoprotein S) gene's influence on inflammation were Joanne Curran, Ph.D., and Ahmed H. Kissebah, M.D. ...

Newly discovered birdlike dinosaur is oldest raptor ever found in South America

...rt of Evolving Planet, a permanent exhibition that opens March 10, 2006. Drifting continents About 200 million years ago, all of the Earth's land was amassed in one supercontinent called Pangaea. During the Middle and Late Jurassic, Pangaea split into two landmasses. Laurasia, composed of North Americ...
