Selection

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

Accurate diagnosis of cancer subtypes remains a challenging problem. Building classifiers based on gene expression data is a promising approach; yet the selection of non-redundant but relevant genes is difficult. The selected gene set should be small enough to allow diagnosis even in regular clinical laboratories and ideally identify genes involved in cancer-specific regulatory pathways. Here an...

Cornell finds natural selection in humans

The most detailed analysis to date of how humans differ from one another at the DNA level shows strong evidence that natural selection has shaped the recent evolution of our species, according to researchers from Cornell University, Celera Genomics and Celera Diagnostics. In a study published in the Oct. 20 issue of the journal Nature, Cornell scientists analyzed 11,624 genes, comparing h...

Natural selection at single gene demonstrated

Biologists seeking elusive proof of natural selection at the single-gene level have a powerful new tool at their disposal. Chris Toomajian, postdoctoral researcher in molecular and computational biology in the USC College of Letters, Arts and Sciences, led a group that sought to replace the standard neutral model, a common but unrealistic test for natural selection, with a statistical meth...

Embryonic selection of sex avoids conceiving blind children

The Assisted Reproduction Unit at the Quirón Hospital in Donostia-San Sebastián has managed, for the first time in the Basque Country, to successfully carry out an embryonic sex selection in a woman who is a carrier of the disease Retinosis Pigmentaria, linked with the X chromosome ?in order to avoid giving birth to a male child. Retinosis Pigmentaria is a hereditary illness of the eyes of...

Does natural selection drive the evolution of cancer?

The dynamics of evolution are fully in play within the environment of a tumor, just as they are in forests and meadows, oceans and streams. This is the view of researchers in an emerging cross-disciplinary field that brings the thinking of ecologists and evolutionary biologists to bear on cancer biology. Insights from their work may have profound implications for understanding why current...

Malaysia Likely To Outlaw Gender Selection Test

Malaysian Health Minister Chua Soi Lek has said that the country could be restricting a fertilization test that allows parents to select their baby's sex//. This is being done for the fear that most potential parents will choose boys. 'We are not against infertile couples seeking medical treatment to have babies, but they should not choose the sex,' Chua said. But he added that such p...

UK Government to Outlaw Sex Selection of Babies

The UK government has planned to outlaw sex selection of babies for non-medical reasons as part of its shake-up of embryology regulation.// Health Minister Caroline Flint has told Parliament that she intended to introduce a "clear and specific ban" on the use of techniques to choose a gender of baby, saying that allowing such practices among parents-to- be could be the start of a "sli...

Parental Role In Embryo-Selection Urged

The Government is pondering over a report suggesting that legal changes be made to enable parents to decide the sex of their progeny through embryo selection.// Sex- selection, by analyzing an embryo's genetic make-up, is prohibited in New Zealand, Britain and most of Europe, but not in the States. The report further urges that parents be given the option of selecting embr...

Selection of Best X Chromosome in Women

A University of Warwick physicist has uncovered how female cells are able to choose randomly between their two X chromosomes and why that choice is always lucky . Human males have both a X and a Y chromosome but females have two X chromosomes. This means that in an early stage in the development of a womans fertilised egg the cells need to silence one of those two X chromosomes. This p...
