Hitachi Soft develops low-cost human genome DNA chip

October 8, 2002, 08:23 AM —  IDG News Service — 

Hitachi Software Engineering Co. Ltd. and a Japanese venture DNA Chip Research Inc. have jointly developed DNA (deoxyribonucleic acid) chips that carry about the same number of genes as the full human genome and have succeeded in making them cheaper than current DNA chips. The product is expected to be available in November, the companies said Tuesday.

DNA chips -- also known as DNA microarrays -- are devices used in diagnostics and fundamental biological research that carry fragments of DNA on a base, such as a piece of glass. They can allow researchers to monitor a complete set of genes on a single chip and therefore gain a better picture of the interactions among thousands of genes simultaneously. They can also enable researchers to find a gene involved in a disease by chemical reactions with samples taken from a patient's blood or tissue.

The new Human Oligo Chip 30K comes with a set of three chips that carries a total of 30,000 human genes, equivalent to the number in the full human genome, according to Hitachi Software's Website.

Using bioinformatics techniques, Hitachi Software and DNA Chip Research computerized each company's gene arrangement database and designed the chips. This method simplified the process and reduced the cost usually required for making conventional DNA chips, which carry around the same amount of genes.

While the conventional DNA chips are priced around from

Either way you look at it Microsoft Data Center management did not follow standards or best practices in this failure. In which case it makes me wonder more about the outsourcing of corporate data much less personal data.

AISO founders envisioned a Web hosting company that was environmentally friendly. While the company employed energy-efficient innovations like solar panels, its infrastructure produced unacceptable power and cooling requirements. Find out how AISO leveraged AMD technology to overcome their challenge in this case study white paper.

In this whitepaper, Scalar explores the opportunity to change the landscape with respect to mission critical databases built around Oracle. Leveraging technologies such as Linux, high-end commodity processing power and Oracle RAC technology to architect, design, build and maintain database infrastructure that delivers maximum availability, reliability and performance at a fraction of traditional cost.

On a typical day, weather.com, the Web site for The Weather Channel in Atlanta, serves up between 15 million and 20 million page views. But in September 2004, when back-to-back hurricanes ransacked Florida, the peak traffic on one day more than tripled: over 70 million page views by more than 7 million unique visitors.
