Drawing with DNA: 'Bioart' illuminates genomics

...through and produce vast amounts of data. Everyday applications include genetic medicine and pharmaceuticals. Yet this process and, more generally, genomics remain dimly understood by the public. "Ecce Homology," an interactive "bioart" installation to be showcased at SIGGRAPH 2005 ?in Los Angeles, July 31 throu...

Endocannabinoids ?the brain's cannabis ?demonstrate novel modes of action to stress

...in various stress-related situations with possible applications in eating, disease treatment and social behavior. Tulane, LSU team on stress-related shutdown The team from Tulane and Louisiana State Universities, led by Shi Di, found that in both physiological and psychological stress situations, stress hormone...

Beetle-inspired switch uses water for bonding

... The switches can be combined in arrays for larger applications like powerful adhesive bonding. Like the transistor, whose varied uses became apparent only following its invention, the uses of the new switch are not yet understood. But the switch's simplicity, smallness and speed have enormous potential, accordin...

For first time, brain cells generated in a dish

... that, they learned vital information for clinical applications such as bone marrow transplants. Now we have a tool to do exactly the same thing." By watching the cells perform, scientists can make judgments and influence the capacity of the cells to generate specific neurons. "As far as regenerating parts of t...

Tagging pathogens with synthetic DNA 'barcodes'

...ersion of the journal. The idea is one of several applications the researchers have found for what they call "dendimer-like DNA," consisting of many short Y-shaped strands of DNA linked together in a treelike structure. The DNA that carries the genetic code in living cells consists of two complementary strands t...

New Lab Research May Help Those Deafened By Immune System Attack

...rgans of Corti of guinea pigs. The U-M has patent applications pending in the U.S. and abroad pertaining to KHRI-3, IESCA and AISNHL. The University, Carey and several colleagues stand to profit if tests or treatments based on these patents are developed. The development of a clinical test for patient antibody t...

Nanowires can detect molecular signs of cancer, scientists find

...the journal's web site. "This is one of the first applications of nanotechnology to healthcare and offers a clinical technique that is significantly better than what exists today," says author Charles M. Lieber, Mark Hyman Jr. Professor of Chemistry in Harvard's Faculty of Arts and Sciences. "A nanowire array ca...

Quantum dots provide a faster, more sensitive method for detecting respiratory viral infections

... result, this could be one of the earliest medical applications of nanotechnology, Wright and Crowe say. The researchers' next step will be to develop a quantum dot cocktail capable of simultaneously detecting the presence of at least five major respiratory viruses: influenza A and B, parainfluenza and metapneum...

Hopkins scientists uncover 'tags' that force proteins to cell surface

...ickly, but Li cautions that any potential clinical applications will require understanding exactly how the tag helps the protein's transportation. Among the "problem proteins" are those that detect odors in the nose, and the protein that's faulty in cystic fibrosis. Being able to force these to the cell surface...

Organic farms produce same yields as conventional farms

...arm that used recommended fertilizer and pesticide applications with an organic animal-based farm (where manure was applied) and an organic legume-based farm (that used a three-year rotation of hairy vetch/corn and rye/soybeans and wheat). The two organic systems received no chemical fertilizers or pesticides. I...

New bioinformatics technique for systematically analyzing key regions in DNA that help control gene activity

...incomplete and uncertain data. It has been used in applications ranging from medical and financial data analysis to voice recognition and image processing. Applied to gene regulation, the approach was able to predict the location of regulatory sites for about one-third of the genes in the yeast genome - a success...

New technique may speed DNA analysis

...esses, and the more we can detect them." SuNS has applications beyond DNA microarrays. Materials both organic and inorganic (metal nanoparticles, for example) can be made to assemble along a pattern composed of DNA strands. This makes SuNS a versatile technology that could be used to produce other complex nano-d...
