Welcome to the fourth edition of the Molecular and Cell Biology Carnival! Let's get down to business right away...
FParrish presents Fly Flight Simulators: Science Videos - Science News - ScienCentral posted at Flies Playing Video Games...Could Lead To New Flying Robots. This is hands-down the most interesting submission of today's carnival, so I suggest you watch their YouTube video to find out more.
Phil B. presents Evolution is Dead posted at Phil for Humanity. This might be considered a controversial post, but I wanted to include it in this edition. Phil does not usually write strictly about science, but it is great to see that people who are not "in the works" take interest in these topics.
GrrlScientist is the biggest contributor to today's edition (and I would like to invite her to become a host for one of the next editions). Her contributions are:
For the ones who think it's time for protein-interaction talk, 96well presents just another protein-interaction model, posted at Reportergene.
In this section, we have a submission regardin career options for biologists, and a funny letter by a human-created organism:Khan presents Byte-Savvy Biologists, while Paras Chopra gives voice to the new organism in This is Synthia talking.
That concludes this edition. Submit your blog article to the next edition of molecular and cell biology carnival using our carnival submission form, or sending me an e-mail (address in the right column of this blog). Past posts and future hosts can be found on our blog carnival index page. We are still looking for hosts -- so if you are interested in hosting this blog on one of the second Sundays of the next few months, give me a shout!

As a brief follow up to the post about Dr. Andras Pellionisz's Google seminar, I cannot help but quote from his website:
Since a US Government-mandated (and taxpayer paid) 4-year study (ENCODE, led by Dr. Collins) established the scientific fact that (at the least a significant part of) formerly "written off" so-called "non-coding DNA" is massively involved in genome function, US government-supported professionals who after the release of ENCODE (reversal of the Establishment in 2007) neglect to to follow Dr. Collins' mandate that "the scientific community will have to re-think long-held beliefs" are actually liable for a hefty Class Action Lawsuit for Negligence when they disregard the established reversal of protocol and e.g. continue to "write off" investigation of 98.7% of the DNA in cases of grave genomic syndromes.I really try to be fair with people like this, but woah. Can researchers be charged with negligence for what they don't study? (Assuming, that is, that there actually was a total dismissal of non-coding DNA, which there wasn't).

The talk was a Syracuse Symposium event, and the first big event ever to be held in Syracuse University’s new $110 million Life Sciences Center. I thought it was fitting that the first event to celebrate the future of the new life sciences building was a lecture that examined the collective genetic journey of mankind.
Dr. Wells began by giving the audience a very brief introduction about DNA and genetic genealogy. He included a great quote that “The question of origin is actually a question about genealogy.” For those that are not familiar with the Genographic Project, it was launched in 2005 and includes three primary missions:
Dr. Wells is a great speaker and the hour-long lecture went by extremely quickly. Some of the more interesting information he shared is not readily available on the Genographic Project’s website:
He also highlighted the previous papers that resulted in party from the Genographic Project, including:
A new paper, soon to be released, will examine the genetic ancestry of the Toubou people indigenous to northern Chad in Saharan Africa. The Toubou people have a rich and interesting history, but their actual genetic roots are unclear. According to Sougoui, a Toubou:
Dr. Wells showed a short clip of a new documentary that is being made about the Genographic Project. In the clip, we were shown the challenges of collecting DNA from the Toubou; looks like it will be another very interesting documentary. See more about the Toubou project here and here.
The Q&A Session
During the Q&A session, someone asked what regions are missing from the database. Perhaps unsurprisingly, the answer was the Americas and Australia. Apparently the Project has had a very difficult time getting permission to take samples from these populations.
Many of the questions reflected the fact that many people are confused about the inheritance of Y-DNA and mtDNA. Half the them were about whether a child or a sibling would have the same or different Y-DNA or mtDNA.
Dr. Wells is a great lecturer, and I highly recommend watching him speak if you are ever able to do so. I learned a great deal about the Genographic Project, and I look forward to the information that will continue to be released from this valuable endeavor.

I’ve just come across MyFamilyHealth, an interesting genetic/PHR service:
But they are open to health organizations as well.

The mission of Webicina is to build a bridge between medical professionals and e-patients by providing e-learning tools, personalized packages and online image building solutions. Webicina aims to help physicians make their online activity as efficient as possible and help patients how to find reliable medical information online.
Budapest, Hungary (PRWEB) November 6, 2008 — “Web 2.0 for physicians and patients”, that is the motto of Webicina, an online service focusing on how medical professionals of the 21st century can meet the expectations of e-patients and how patients can find reliable information and web 2.0 services about a specific medical condition.
E-patients are patients who try to find relevant medical information on the web; want to communicate with their doctors via e-mail or IM; share health stories in patient community sites and store their medical files online. They will change the way medicine is practiced and most of physicians are not ready for this challenge.
Webicina offers personalized medicine 2.0 packages that provide patients and physicians with all the web 2.0 tools they need to know about a medical specialty or medical condition. Patients who are interested in diabetes receive all the selected, quality blogs, blog carnivals, community sites, videos, slideshows, etc. focusing on diabetes in a digestible format.
It also helps doctors how to build a proper online reputation and the e-learning tools were designed to let them learn how to launch a successful medical blog; how to organize medical meetings in the virtual world of Second Life; and how to follow the medical literature more easily. Free e-courses are accessible without registration.
“We are sure web 2.0 can change the way healthcare is delivered and while the number of e-patients is growing rapidly, the number of web-savvy doctors is not, so we must help them to understand each other and be ready for the challenges web 2.0 sets up.” said Bertalan Mesko, founder of Webicina.com.
For more information, or to schedule an interview, please contact Bertalan Mesko.

re-posting from NARSAD news ... FDA approves an amazing new form of non-invasive magnetic brain stimulation for treatment resistant depression.
Great video demonstrates the methodology and its ability to interfere with neural processing with a high degree of temporal and spatial specificity. A new treatment that one day might be guided by genomic markers ? Perhaps.

Thanks so very much to the folks at SNPedia for developing and sharing the Promethease analysis tool. What a delight to delve into my 23andMe profile ! I stumbled onto the usual dreary risks for this and that, and yes, I know I'm at risk for baldness, but did come up with a few bonus IQ points and moreover an allele that protects me from cannabis dependence (will have to return to Nijmegen sooner than later I suppose).

Like "Joe the Plumber" (whose real name is Samuel), CNTNAP2 (whose real name is CASPR2) has achieved a bit of fame lately. While recently appearing almost everywhere (here, here, here) except FOX News, CNTNAP2 (not Joe the Plumber) is apparently a transcriptional target of the infamous FOXP2 "language gene" - so says Sonja C. Vernes & colleagues [doi: 10.1056/NEJMoa0802828] who precipitated DNA-protein complexes using anti-FOXP2 antibodies from a cell line transiently expressing FOXP2. The team later evaluated measures of expressive and receptive language abilities and nonsense-word repetition and found that a series of snps - most significantly rs17236239 - were associated with performance of children from a consortium of families at risk for language impairment. This adds to several previous reports of CNTNAP2 and risk for autism, a disorder where language ability is severely impaired.
So what's all the fuss ? How can something so insignificant (rs17236239 not Joe the Plumber) stir up so much trouble ? Well, as reported in a previous post, the expression of CNTNAP2 in the developing superior temporal cortex may be a relevant clue since this brain region is activated by language tasks. Also, this gene encodes a rather massive protein which (as reported by Coman et al.,) seems to participate in the establishment of myelination and "nodes" that permit rapid neural transmission and long-range coordination across neural structures in the brain. Interestingly, this gene shows evidence for recent positive selection in humans (as posted on here and here) although the newly derived G-allele at rs17236239 seems to be the allele that is causing the language difficulties. My own 23andMe profile shows a middling A/G here which makes it slightly hard to recall and repeat "Samuel Wurzelbacher".
