An entropy-based gene selection method for cancer classification using microarray data

... presents an entropy-based iterative algorithm for selecting genes from microarray data that are able to classify various cancer sub-types with high accuracy. In addition, the feature set obtained is very compact, that is, the redundancy between genes is reduced to a large extent. This implies that classifiers...

'Jumping genes' contribute to the uniqueness of individual brains

...iversity with the help of mobile elements and then selecting for the fittest is restricted to the brain and leaves other organs unaffected. "You wouldn't want that added element of individuality in your heart," he adds. Precursor cells in the embryonic brain, which mature into neurons, look and act more or le...

NHGRI Selects 13 More Organisms for Genome Sequencing

The first challenge is selecting appropriate patients, which is crucial, since the patients most likely to survive would be those who are quite sick, but not too sick to be beyond help. This fine line in determining which patients are optimal will need to be defined by future clinic...

Picking particles faster than one at a time

By concentrating on the highest quality particles, crystallization in silico may need far fewer than hundreds of thousands o...

New peptide antibiotic isolated from American oyster

Novel molecular 'signature' marks DNA of embryonic stem cells

...e "gatekeeper." It accomplishes the latter task by selecting which genes to make active or inactive in a cell, based on the nearby chemical tags joined to its backbone. By examining the chromatin in mouse ES cells across the genome, the scientists discovered an unusual pair of overlapping molecular tags in the...
