Detection of DNA on nanotubes offers new sensing, sequencing technologies

... of two complementary strands, each resembling the side of a ladder and having a specific sequence of nucleotide bases as rungs. Hybridization refers to the spontaneous binding of two complementary strands through base pair matching. By wrapping one strand of DNA around the surface of a carbon nanotube, ...

'Uniquely human' component of language found in gregarious birds

...sh. "Now we find that we have been joined on this side of that boundary by the starling. It should no longer be considered an insult to be called a bird brain." Although they are not known for the lilting beauty of their songs, starlings produce an amazing array of complex sounds, combining chirps, war...

Light activated anticancer drug targeted to DNA using cisplatin like sub-units

...tin analogs in attempts to find treatments without side effects. One approach to analog development is light activated drugs, or photodynamic therapy (PDT). Now a Virginia Tech chemistry-biology research team that has been working on both non-cisplatin drugs and cisplatin analogs has combined their findin...

Waking a sleeping virus

...ules revealed that one copy of ZEBRA plugs a large side chain into a deep pocket in the other. "This is an ideal type of structure to try to target with a drug," Petosa says. "If we can find a molecule to block access to the cavity, the copies wouldn't be able to bind to each other and dock onto DNA." Mo...

The discovery of this novel mechanism, garnered through the study of three different vertebrates (frogs, chickens and zebrafish), marks the first time that a single common mechanism has been identified in left-right patterning in three...

Tool developed to silence genes in specific tissues using RNAi

...numbers of cell types or tissues, thereby reducing side effects." Equally, the technique can help researchers determine the function of a single gene in a single tissue, which "is potentially a powerful investigative tool," Wilkinson says. "By silencing a particular gene in a specific tissue, you can lea...

Cracking the genetic code for control of gene expression

... regions where many transcription factors bind DNA side by side. Finding the same region with high frequency of transcription factors in several species indicates that the DNA element regulates gene expression. The researchers showed that the predicted regulatory elements direct organ-specific expression ...

A flip side is that people with these lesions tend to associate familiar stimuli with new information more rapidly than healthy counterparts, a phenomenon called attention switching. This suggests that learning to ignore stimuli and rapid attention switching ar...
