What does cloning do to the stem-cell debate?

OK, so the whole stem-cell debate in congress mostly revolves around the fac that, as Bush put it, “…extracting the stem cell destroys the embryo, and thus destroys its potential for life,” and opponents of embryonic stem-cell research suggest scientists should focus on adult stem cells that don’t have that potential. Which just makes me wonder, what happens if (or when) science advances to the point where human cloning is possible? Would adult stem cells be verboten as well? What happens when blood cells and dead skin have the “potential for life?”

Singing sands

OK, this is too cool. From Physics News Update (with thanks to Strata for the link):

For centuries, world travelers have known of sand dunes that issue loud sounds, sometimes of great tonal quality. In the 12th century Marco Polo heard singing sand in China and Charles Darwin described the clear sounds coming from a sand deposit up against a mountain in Chile. Now, a team of scientists has disproved the long held belief that the sound comes from vibrations of the dune as a whole and proven, through field studies and through controlled experiments in a lab, that the sounds come from the synchronized motions of the grains in avalanches of a certain size.

You can hear recordings of singing avalanches from CNRS labs, and Prof. Melany Hunt at caltech has some movies of creating singing avalanches on her website.

Freedom of speech, if you don’t mind walking

Today’s WSJ has a story on how the FBI threatened to take away Moroccan immigrant Yassine Ouassif’s green card if he didn’t become an informant (behind a pay wall, sorry, a summary is here). Down at the bottom of the story is this bit:

Ms. Aklaghi [Ouassif’s lawyer] says she learned more at that point about why federal authorities were so interested in him. Mr. Ouassif had been secretly recorded by an FBI informant talking to friends in a San Francisco mosque. A Homeland Security lawyer, she says, did not specify what Mr. Ouassif had said, but told her that his statements did not indicate criminal intent and were fully protected by the First Amendment. Nevertheless, his statements had landed him on the no-fly list, Ms. Aklaghi says, and led to all his subsequent travails.

So, if her information is correct, what this says is that Homeland Security is taking the position that though the First Amendment stops the government from “abridging the freedom of speech,” it doesn’t say anything about taking away someone’s ability to board an airplane if he says something we don’t like.

Homeland Security, of course, is not commenting at all, which points to the other big problem with all this nonsense: the people currently running the show are so secretive (and our congress so complicit) that it’s almost impossible to find out what’s actually being done in our name. Where’s the transparency? Where’s the freedom to be left alone when you’re doing nothing wrong? This is not how the America I learned about in civics class works. We deserve better — a lot better.

Update 7/12/06: corrected spelling of Aklaghi’s name.

Cornell cracks European GPS DRM

Galileo is the EU’s first global navigation system, and unlike the US GPS system is partially funded by private investors. Part of their business model is to sell their data, so they’ve added noise to the signal using a pseudo-random number sequence, with the intention of selling the “offsets” to licensed manufacturers of GPS receivers. Now researchers at Cornell have decoded that sequence, using statistical analysis of the signal. From the Cornell press release:

Afraid that cracking the code might have been copyright infringement, Psiaki’s group consulted with Cornell’s university counsel. “We were told that cracking the encryption of creative content, like music or a movie, is illegal, but the encryption used by a navigation signal is fair game,” said Psiaki. The upshot: The Europeans cannot copyright basic data about the physical world, even if the data are coming from a satellite that they built.

The moral of the story: just because people benefit from your work doesn’t mean they’ve agreed to pay you, and business plans don’t carry the force of law.

LiveJournal-integrated Jabber

Interesting: Livejournal has just launched a Jabber server, and are developing integrated features like posting via Jabber and of course integrated Friends and Buddy lists. And they’ll be federating, so you’ll be able to talk to other Jabber-enabled systems (like GMail/GTalk) without the usual mucking about in monopoly-space (you know, like you do with AIM, MSN, Yahoo! Messenger, and all the other dark-age services that still wish it was 1990).
