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

...ays. Here an entropy-based method is proposed that selects genes related to the different cancer classes whil...h of the partitions. A leave-one-out approach then selects the most commonly selected genes across all the different runs and the gene selection algorithm is a...

Proteomics brings researchers closer to understanding microbes that produce acid mine drainage

...ironment drives the community, how the environment selects for the membership of the community, and then what are the feedbacks from growth of these organisms that result in changes in the environment," Banfield said. "The proteomic approach will allow us to begin to understand how organisms change their beh...

DNA size a crucial factor in genetic mutations, study finds

...li's DNA polymerase I-moves along the template and selects the corresponding base to create a new base pair. DNA bases fit into a specialized site on the enzyme before they are bonded to the template. Kool wanted to see how the enzyme reacts if the bases are not the usual size. ''The idea was to see how DNA...

Scientists force viruses to evolve as better delivery vehicles for gene therapy

...volution - the genetic variation from which nature selects the best-adapted organism - the researchers created mutant viruses by introducing small variations in the genes through an error-prone polymerase chain reaction (PCR) coupled with a test tube recombination technique. After reassembling the mutant vir...

Speeding discovery of the 'human cancer genome'

...etastasis is a multistep process that requires and selects for tumor cells capable of escaping their normal microenvironment, traversing into and out of lymphatic or blood vessels, and proliferating in new "soil," the researchers said. Metastasis is particularly important in skin cancer, Chin added, as th...

American scientist's research of life's first cells

...perties of molecules in a cell. A judging panel selects the GE & Science Prize for Young Life Scientists grand prize winner and may present regional awards in four geographic regions: North America, Europe, Japan and all other countries. These regional winners receive $5,000 awards. In addition to the...

Brain fends off distractions

... Social-psychologist Veling proved that the brain selects incoming information to remember useful things. Distracting information is refused and neutral information may enter. In the event of tiredness, this system no longer seems to work. Test Psychologists carry out a lot of research into the for...
