Secrets of the HIV genome revealed

By | August 6, 2009, 6:02 AM PDT

This week’s Nature has what we journalists call a “get.” (Picture from the Weeks Lab.)

Architecture and secondary structure of an entire HIV-1 RNA genome” is, like a great movie, everything you were promised and more.

We’re not just talking about a map of the gene that causes HIV. We’re talking of a complete structural diagram of the RNA through which it reproduces.

A team headed by Kevin Weeks of the University of North Carolina (Go Tarheels) not only teased out the gene sequence, but its shape. That shape is vital to understanding how to defuse the virus.

As Weeks himself noted in a press release, “”There is so much structure in the HIV RNA genome that it almost certainly plays a previously unappreciated role in the expression of the genetic code.”

It’s in knowing the angles at which atoms intersect within a molecule that you can find the key which unlocks and destroys the gene.

As is often true in science, Weeks has already discussed all this publicly, having held a seminar at Hunter College in New York about his findings in May. But as is also true in science, it’s not real until it’s published in a fully peer-reviewed journal.

Weeks has a more complete description of the work at his Web site. “we want to make it possible to understand, in detail, the global structure and long-range architecture of all cellular RNAs,” he writes, and thus understand fundamental assembly principles for RNA.

This, then, is not even a great AIDS story. It is basic chemical-genetic research of the highest order, a path toward unlocking the secrets of all deadly viruses.

One other important point I found on Weeks’ background. He did not come to this from some big-time school like Harvard or Stanford. He is a 1986 graduate from the College of Wooster, in Ohio, where he was discovered by the Fulbright Scholar program and sent to Germany.

Genius can start anywhere. If you’re launching your collegiate career at a lesser-known college this fall, remember that and aim high.

Dana Blankenhorn has been a technology reporter since 1982, a business reporter since 1978, and a writer for as long as he can remember. His Schwab IRA has a few tech stocks in it, most notably some Intel and Applied Materials bought over 10 years ago. But the vast majority of his tiny fortune (emphasis on the word tiny) is invested in mutual funds. He presently writes for no one else but ZDNet, SmartPlanet and himself. But if you've got an opportunity let him know. If he takes the gig he"ll first add it to this disclosure page.

He writes for SmartPlanet and is not an employee of CBS.

RE: Secrets of the HIV genome revealed
View the new documentary "House of Numbers" to see why questions
about this new strain must be raised and deeper issues about HIV and
AIDS need to be discussed. Lives are at risk, and this is the first
documentary with the worlds foremost authorities highlights the scientific
problems with HIV testing, science, statistics, and why there is no cure.
It sheds new light on a misunderstood phenomena. GO to
houseofnumbers.com to see the trailer
