DNA scans and scams, backed by Google


Your innermost secrets, stored to an online database. Genetic profiling firms promise insights, but deliver unfounded health scares.

For about US$1,000, Mountain View, Calif.-based 23andMe will tell you a thing or two about your genetic makeup.

Google, which collects as much intel as it possibly can about individuals, and has many close CIA ties, is one of the 23andMe’s backers.

23andMe analyzes saliva samples from its customers, to provide rudimentary information about your genetic predispositions to baldness, or developing prostate cancer.

The site does not currently make interpretations about a user’s risk for developing such diseases as cancers, Alzheimer’s disease and diabetes, though users could in some cases get help from experts to make some basic assessments.

But the service may prove controversial in countries like Britain, where some experts say DNA tests are often of little value and can trigger unnecessary health worries.

DNA know the power of attraction

Chemists discover “genetic telepathy” 


Stuck on you. DNA double helices with identical nucleotide sequences draw together, spontaneously.

Bits of identical DNA, separated by water only, will draw together–but only if they are the same, according to chemists at the Imperial College of London.

The ICL chemists do not know how the identical double helices recognize each other. They suggest that the curvature of the helices, being a match, might stress the medium between them in a way that brings them together.

Electrostatic charges might also be responsible for this DNA “telepathy.”

DNA Double Helices Recognize Mutual Sequence Homology in a Protein Free Environment
We have observed spontaneous segregation of the two kinds of DNA within each spherulite, which reveals that nucleotide sequence recognition occurs between double helices separated by water in the absence of proteins, consistent with our earlier theoretical hypothesis. We thus report experimental evidence and discuss possible mechanisms for the recognition of homologous DNAs from a distance.
