New electrostatic-based DNA microarray technique could revolutionize medical diagnostics

A new method for reading DNA (or RNA) microarrays is based on measuring the electrostatic repulsion between silica microspheres and hybridized DNA. Surface areas containing double-stranded DNA (red) or single-stranded DNA (blue) can be easily disting ...

New Electrostatic-Based DNA Microarray Technique Could Revolutionize Medical Diagnostics

BERKELEY, Calif., June 30 (AScribe Newswire) -- The dream of personalized medicine — in which diagnostics, risk predictions and treatment decisions are based on a patient's genetic profile — may be on the verge of being expanded beyond the wealthiest of nations with state-of-the-art clinics. A team of researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has invented a technique in which DNA or RNA assays - the key to genetic profiling and disease detection - can be read and evaluated without the need of elaborate chemical labeling or sophisticated instrumentation. Based on electrostatic repulsion - in which objects with the same electrical charge repel one another - the technique is relatively simple and inexpensive to implement, and can be carried out in a matter of minutes.

First DNA Molecule Constructed from Mostly Synthetic Components

ScienceDaily is reporting that Japanese chemists have created the world's first DNA molecule comprised of almost entirely artificial components. The breakthrough could lead to advances in both medicine and technology, possibly utilizing the massive storage capacity of DNA. "In the new study, Masahiko Inouye and colleagues point out that scientists have tried for years to develop artificial versions of DNA in order to extend its amazing information storage capabilities. As the genetic blueprint of all life forms, DNA uses the same set of four basic building blocks, known as bases, to code for a variety of proteins used in cell functioning and development. Until now, scientists have only been able to craft DNA molecules with one or a few artificial parts, including certain bases.

New Cuil Search Engine Unveiled

A new way to search the web was unveiled on Sunday. The new service, called Cuil (sounds like "cool"), is the brainchild of four former Google search experts. What Cuil brings to the table is a new way to search based on each page's content instead of relying on links and traffic patterns. Cuil claims that its technology can index a greater portion of the Web far cheaper and faster than can Google. In fact, Cuil claims to have indexed 120 billion Web pages compared to the 40 billion currently indexed by Google. Another difference is that Cuil claims it has no need to store user information based on previous web searches because it focuses on content and not click history. Whether it can post a serious threat to Google remains to be seen as challenging the giant is a daunting task as even the likes of Microsoft have discovered.

Newegg Defies New York Sales Tax Law

JagsLive informs us that the electronics retailer Newegg.com is defying New York lawmakers; it has suddenly stopped collecting sales tax from New York online shoppers. The "Amazon tax," which went into effect June 1, requires online merchants to collect sales tax if they have any affiliates in the state. Amazon is complying but has sued the state on constitutional grounds. Overstock.com dropped all of its New York affiliates and then joined the Amazon lawsuit. Newegg started out complying with the law on June 1, but stopped collecting taxes for New York on August 21.
