But are frame rates worth that much money? Can any graphics card that won't also cook your dinner and wash your car be worth that kind of scratch? And with DirectX 10 not exactly wowing us, is a first-generation DirectX 10 card worth any money at all?"

Feed Wild Sheep Descended From Single Pair Show Surprising Genetic Diversity (sciencedaily.com)

From feed by sdfeed
Reconstructing the genetic history of a population of mouflons (wild sheep) descended from a single pair, scientists have demonstrated that the animals' genetic diversity increased over time, contrary to what the usual models predict. These results contradict the belief that a population descended from a small number of individuals will exhibit numerous deficiencies and reduced genetic diversity.

Biomedical engineers have adapted a three-dimensional ultrasound scanner that might guide minimally invasive brain surgeries and provide better detection of a brain tumor's location. Brain surgeons currently rely primarily on two-dimensional images produced by MRI or ultrasound.

Submission + - Dell replacing faulty LCD screens

Submitted by Anonymous Coward
An anonymous reader writes: Dell responds to customers who created a Web site to complain that some LCD screens developed a one pixel-wide vertical line by offering free replacements of the displays. According to the Web site, unless a faulty LCD screen is replaced, it can develop a permanent vertical line one pixel wide, either stuck on a single color or reflecting the color displayed behind it. ell first responded to the issue in April, offering to replace certain 17-inch displays on Inspiron 9200, Inspiron 9300 and XPS Gen 2 notebooks sold between November 2004 and October 2006. On Tuesday, Dell expanded its replacement program to include six more models, including the Inspiron 6000 and 8600, Latitude D800 and D810, and Precision Mobile Workstation M60 and M70 notebooks sold between December 2004 and December 2006. Some of those models use a faulty component that can generate the line over time, according to a posting on Dell's corporate blog by Lionel Menchaca, Dell's digital media manager. Dell will now replace any LCD screen affected by this issue within three years of purchase, or will refund customers who were forced to pay for their own replacements, Menchaca said.

Submission + - PC-BSD "24-hour test drive" (arstechnica.com)

Submitted by Tyler Too
Tyler Too writes: Ars Technica has a '24-hour test drive' of PC-BSD, a FreeBSD-based distribution designed to appeal to Windows converts. The overview covers installation, configuration, and usage. 'Just about everything you need to make a useful FreeBSD development system is there. The ports system is quite powerful and has inspired entire Linux distributions (see Gentoo), but it is often faster just to grab a compiled package. If the package you are looking for is not in the PC-BSD PBI repository, then you have the option of using regular FreeBSD packages or ports to fill the holes.'
