New ion trap created on silicon.

Ion-trap technology uses electric and magnetic fields to isolate a charged particle from its environment -- a prerequisite for exploiting the temperamental quantum properties of electrons. Although ion traps are just one technology for building a quantum computer, they have the longest history -- the first trap was built in Monroe's lab in 1995 -- and they've advanced the furthest.
P2P traffic on the rise.
Quote
The temporary plateau and slight decline of the P2P population represents a normal cyclical pattern associated with the file-sharing community. Various reasons, such as returning or departing college students, broadband penetration, computer and MP3 player sales, all have an impact on the strength of the P2P community. While the behavior of these factors may result in a minor decline or stagnation, the overall trend has been unprecedented growth. Indeed, the month of November 2005 represents one of the strongest months yet with a total of 9,465,000 total connected users - third only to August and July with 9,620,000 and 9,496,000 total connected users.
Natural selection forms human DNA.
Quote
This analysis suggested that around 1800 genes, or roughly 7% of the total in the human genome, have changed under the influence of natural selection within the past 50,000 years. A second analysis using a second SNP database gave similar results. That is roughly the same proportion of genes that were altered in maize when humans domesticated it from its wild ancestors.
