Nanofluidics Identify Epigenetic Changes One Molecule at a Time

(PhysOrg.com) -- Using a system of nanofluidic channels and multicolor fluorescence microscopy, a team of investigators at Cornell University has developed a method that analyzes the binding of DNA and DNA-binding proteins ...

Spying on a cellular director in the cutting room

Like a film director cutting out extraneous footage to create a blockbuster, the cellular machine called the spliceosome snips out unwanted stretches of genetic material and joins the remaining pieces to fashion a template ...

Rapid, Inexpensive DNA Sequencing Moves Closer to Reality

As efforts such as The Cancer Genome Atlas and others generate vast quantities of information about the genetic makeup of different types of cancer, it is becoming increasingly clear that such information has great potential ...
