This solves nothing.

The companies that produce DNA (like GenScript) can make a strand of arbitrary length using any bases. This includes the normal A T C and G, but could also include methylated version as needed.

Testing for methyl groups has been around for a while by using methyl-sensitive DNA cutting enzymes. This procedure would just help you determine which sites to add methyl groups when you are manufacturing your fake DNA. Anyone who has access to a lab (or company) that can make DNA can probably also test for methylation.

One just has to be a bit more careful when producing DNA for crime scenes, though the free market of underground DNA forgers should come in line with the technology soon enough.

Comment Re:Neat, but don't sea cucumbers do something simi (Score 1) 104

A lot of creatures in the ocean do that, usually to startle or distract whatever is chasing them. That wasn't what was so special about it. Most luminous organisms in the ocean glow blue; these glow green, and are rare in that respect (at least in the ocean, see: http://en.wikipedia.org/wiki/Foxfire_(bioluminescence) ). The original publication ( http://www.sciencemag.org/cgi/content/abstract/325/5943/964 ) was only claiming that they found several new species in the deep sea that were unrelated to known organisms. Of course, they have this media-friendly property that they release glowing 'bombs'.

Also, yes, whoever sees it first gets to name it - whatever they want. Obviously this can lead to much silliness.

Scientists Find Way To Combat Forged DNA 45

An anonymous reader writes to tell us that while scientists may have learned how to forge DNA, it appears that a group of Israeli scientists has created a DNA authentication method that is able to distinguish between real and faked DNA samples. "The new process was tested on natural and artificial samples of blood, saliva and touched surfaces, with complete success, Nucleix said. It also identifies 'contaminated' DNA that has been mixed with two or more samples."

They mention in the article they are examining 11 different genes out of over twenty thousand in the whole genome. Obviously they are not concerned with what those genes actually do, but only that certain variants may correlate with improved performance sometimes. The best estimates of heritability of intelligence are somewhere from 30% to 50% genetic, meaning at least half of the variation in intelligence is due to environmental factors or multiple gene interactions.

It's not about global evolution as about treatment effectiveness. If your target protein is rapidly mutating, then selecting against it is likely to either down-regulate that protein or select for other mutations where the antibody binds to reduce binding. Supposing that only 1 in 100,000 cells survive due to that mutation, then you could say that it is still 99.999% effective. But the one surviving cell would be the mutant that proliferates and returns months to years later. It costs millions to develop these treatments and get them through clinical trials. Having it only work some of the time just doesn't seem good enough.

BYU Prof. Says University Classrooms Will Be "Irrelevant" By 2020 469

dragoncortez writes "According to this Deseret News article, University classrooms will be obsolete by 2020. BYU professor David Wiley envisions a world where students listen to lectures on iPods, and those lectures are also available online to everyone anywhere for free. Course materials are shared between universities, science labs are virtual, and digital textbooks are free. He says, 'Higher education doesn't reflect the life that students are living ... today's colleges are typically tethered, isolated, generic, and closed.' In the world according to Wiley, universities would still make money, because they have a marketable commodity: to get college credits and a diploma, you'd have to be a paying customer. Wiley helped start Flat World Knowledge, which creates peer-reviewed textbooks that can be downloaded for free, or bought as paperbacks for $30."

DHS To Use Body Odor As a Lie Detector 206

The US Department of Homeland Security is studying lies, damned lies, and smells. They hope to prove that human body odor could be used to tell when people are lying. The department says they are already "conducting experiments in deceptive behavior and collecting human odor samples" and that the research it hopes to fund "will consist primarily of the analysis and study of the human odor samples collected to determine if a deception indicator can be found."

My guess is that anything Merck would find useful (patentable) they would patent, and leave the rest for this open source project. GSK is doing a similar practice. Part of the motivation is to encourage development of drugs for neglected diseases, that is, diseases where the market is small and big companies like Merck and GSK have no desire to drop the millions to develop the drug that wouldn't help that many people, or would only help poor people.

MD Appellate Ct. Sets "New Standard" For Anonymous Posting 260

A Maryland court of appeals has set what they are calling a new "standard that should be applied to balance the First Amendment right to anonymous speech on the Internet with the opportunity on the part of the object of that speech to seek judicial redress for alleged defamation." The court overturned an earlier ruling that would have required NewsZap.com to turn over the names of anonymous posters who posted negative remarks about the cleanliness of a Centreville Dunkin' Donuts. "In a defamation case involving anonymous speakers, the ruling said, courts should first require the plaintiff to try to notify the anonymous posters that they are the subject of a subpoena. That notification could come in the form of a message posted to the online forum in question, and the posters must be given sufficient time to respond. The plaintiff must then hand over the exact statements in question, so the court can decide whether the comments are obviously defamatory. Finally, the ruling says, the court must weigh the anonymous poster's right to free speech against the strength of the defamation case and the necessity of disclosing the poster's identity."

Designer Babies 902

Singularity Hub writes "The Fertility Institutes recently stunned the fertility community by being the first company to boldly offer couples the opportunity to screen their embryos not only for diseases and gender, but also for completely benign characteristics such as eye color, hair color, and complexion. The Fertility Institutes proudly claims this is just the tip of the iceberg, and plans to offer almost any conceivable customization as science makes them available. Even as couples from across the globe are flocking in droves to pay the company their life's savings for a custom baby, opponents are vilifying the company for shattering moral and ethical boundaries. Like it or not, the era of designer babies is officially here and there is no going back."

Comment Re:vaccine even possible? (Score 1) 177

There are multiple epitopes, or targets, on any viral particle. The first b-cell to multiply and produce antibodies is whatever one sticks first, which is probably the most obvious target and also likely the epitope that mutates the most. A vaccine like this would work but it would have to be designed in a way such that only that one epitope is available for the immune system to generate antibodies. Maybe binding the target protein to nanoparticles and injecting it would work.
