GENETIC SUPERHEROES WALK AMONG US, BUT SHHH! NO ONE CAN TELL ‘EM

GENETIC SUPERHEROES WALK among us but they—maybe you?—don't know it.
Results from a study called the Resilience Project, released today, show 13 "resilient" people—out of over half a million genomes studied—who have genetic mutations that should have doomed them to serious, often deadly,childhood disease. But instead, they've
apparently lived healthy lives into
adulthood.
Wow, you are saying, so how do we get these people into a lab and study their DNA and find cures and get everyone to live happily ever after? Yeah, about that:
The scientists have not been able to
contact those people—not to tell them about their special genetic status nor to do any follow-up research. Research consent forms drawn up long before the
Resilience Project even existed put the kibosh on the idea—yet another example of the tricky issue of consent for genetic studies.
The study, published today in Nature Biotechnology, is the first step for the Resilience Project—it's proof that these resilient people really do exist. And for this first step, the scientists relied on
genomic data originally collected for other studies. Most of the genomes, nearly 400,000 of them, came from people who sent their spit to the sequencing company
23andMe and checked the box on the accompanying form that said it was OK to use their DNA in research. "When you're dealing with a retrospective study, you're
dealing with other people's data," says Jason Bobe, a geneticist at Mount Sinai involved with the Resilience Project. "It's not answering all of your questions. It
doesn't have all the information you need."
The Resilience Project scientists didn't have names or contact information or complete medical records. The team had built a program to analyze genomic data
to find people with mutations for 584 severe genetic disorders, like cystic fibrosis. They sent the program to their partners like 23andMe, the Children's
Hospital of Philadelphia, and the Beijing Genomics Institute, who ran it and returned the anonymized data of 303 candidates. Doing their best to verify using self-reported medical information from the people sequenced, the team winnowed down the candidates to 13 resilient people.
That's where the buck stopped. For some of the data sources, participants had signed consent forms that did not allow them to be recontacted for any reason.
"The last 'generation' of consents and corresponding sample collection for these kinds of large-scale studies were done with out recontact in mind," says Jay Shendure, a genetics researcher at the University of Washington who was not involved in the study. The reasoning went that research labs are not held to the same standard as government-certified clinical labs. And for some people, unwanted genetic information can
be a burden, too—for example, you might donate DNA for a liver study but does that mean you want to know if your DNA later turns up a gene for an unpreventable and
incurable brain disease? Because of these limits, the Resilience Project was not able to verify medical records or, in most cases, resequence the DNA.
23andMe's consent agreement doesn't promise no recontact, but it doesn't explicitly ask for consent to recontact either, leaving it in more of a limbo. Bobe says the Resilience Project has asked 23andMe to work out a process for recontacting the four individuals identified in this study. "While we regularly recontact research participants,"
23andMe said in a statement to WIRED, "it can sometimes be a complex process, involving significant time and resources
and that is the case in this instance."
This recontact consent issue might not be a problem for ever. "Increasingly, research
projects are building participant
engagement into the structure of their research," says Michelle Meyer, a bioethicist at Clarkson University and Mount Sinai. That could mean, for example, keeping patients in the loop when their DNA turns up an unexpected finding like genetic superpowers. Meyer
has also consulted on the next phase of the Resilience Project, which will recruit an additional one million people who will expressly consent to recontact.
Bobe is in charge of this upcoming
prospective study, and he's taking
participant engagement seriously. "I've worked on developing lots of new on ramps for people to experience biomedical research," he says. "I consider myself a biomedical science producer, almost like movie producer." (Though he declined to talk specifics before the prospective study's launch.)
The Resilience Project has certainly its challenge set out. Just consider the typical patient who signs up for a study: It's relatively easy to find and convince a cancer patient to join a study that could
someday cure their disease, but the
Resilience Projection will need to recruit healthy people—healthy people whose protection against faulty genes might only become when they join the study. "We
know we have to achieve very large
numbers. We know it's going to be rare,"says Bobe. But once the team identified those resilient people, they'll finally be able to talk to them.

Online wealth.

I've got little to say about myself. I'm interested in wealth in a legal ways. I've spent time searching for how to make money online without failing in the hands of scammers, without selling Ebooks that will involve one taking illegal steps online too, and at it, I came across some. I'm not going to collect a dime and they're things one can do by oneself. You can get in touch with me and I'll show you. I'm from Nigeria, mentioning Nigeria, I know most of you'll have a kind of funny thoughts. We've got some honest as well as dis honest people everywhere. I'm also going to be posting motivational and inspirational stories to encourage people too. Before I go, I'll like to leave you with something. The least they paid is $1.

WZoneLite – A Pretty Cool WooCommerce Amazon Affiliate Plugin .

Everyone wants to make a million dollars by being a blogger. The promise of riches and internet fame is a big draw to doing it for a lot of people, and I’m sorry to say that the reality of being a blogger (even a professional blogger!) is not quite…as financially lucrative as all that. But that’s not to say that it  can’t be –one of the best ways to start your empire is with an Amazon affiliate plugin. For me, the Amazon Associates program has been one of the biggest earners for me over the years. Not only are there CPM ads like Google Adsense (you know, the normal banner ads we all love to hate), but any time someone clicks a link from your site, you get a percentage of  anything  they buy while the token from your site lasts in their browser. If they buy a song, you get a few cents. If they buy a new MacBook Pro and iPhone? You get…a lot more cents. With that in mind, WZoneLite is a  pretty cool WooCommerce Amazon affiliate plugin that syncs everything together s...

AWS Battles Rivals: Advertising Campaign

Amazon Web Services has defeated IBM in a competition for lucrative federal contracts, threatened Microsoft's core businesses, and reshaped corporate technology. In the last few months, the pioneering cloud-computing unit of the online retail giant has taken a page from the playbook of some of its more traditional competitors: It started advertising. Ads have been splashed across billboards and in airport terminals, television spots and web videos, featuring a whiteboard full of sketches of software architecture and appeals to invent something using Amazon's collection of rented computing services. The advertising campaign, which bears the "Build On" tagline, represents a milestone in AWS' march from technology upstart to one of the major players in business software, technologists and marketers say. For many years, AWS didn't advertise, partly because it didn't have to. The service held a wide lead over the competition, and word-of-mouth was enough to...
