Scientists Convert a 53,000-Word Book Into DNA


digital-dna-600by  | Mashable.com

In a scientific first, Harvard University researches successfully transformed a 53,426-word book into DNA, the same substance that provides the genetic template for all living things. The achievement could eventually lead to the mass adoption of DNA as a long-term storage medium.

Published Thursday in the journal Science, the experiment aimed to demonstrate the viability of storing large amounts of data on DNA molecules. Since the data is recorded on individual nucleobase pairs in the DNA strand (those adenine-guanine/cytosine-thymine pairs you may be straining to remember from high school biology), DNA can actually store more information per cubic millimeter than flash memory or even some experimental storage techs, IEEE Spectrum reports.

The difficulty is in the translation — both to DNA and back again (summarized in the diagram below). The researchers started with the book’s content, which included the text as well as 11 images and a javascript program, and converted it to binary code. Then they assigned every 0 and 1 a nucleobase.

Name: Hitch.me

Quick Pitch: Hitch.me is a dating site for LinkedIn professionals.

Genius Idea: Connects the dating world and the professional world for a secure, safe online dating platform.


After noticing how unsafe some online dating sites are and how many are filled with scammers and sex offenders, Naveed Nadir wanted to fill a void in the online dating world. He decided to marry the dating world and professional world by creating Hitch.me, the first and only dating platform for LinkedIn professionals.

“There are a lot of dating websites out there but most people on those sites lie and have fake profiles,” Naveed Nadir, founder of Hitch.me, told Mashable. “With LinkedIn, people get a sense of security and they feel more comfortable with the network.”

The online dating site lets users browse through profiles of hundreds of LinkedIn professionals all over the world, send them private smiles (without words), pitches (250 characters) and even presentations (private images and videos).

Once you sign into Hitch.me using your LinkedIn account, your professional information, including your LinkedIn photo, is automatically added to your profile. To keep the site professional, users cannot change or modify their profile photo.

Users can then fill out their own personal profile, which includes information such as age, date of birth, interests, photos, etc. Hitch.me’s privacy options lets users limit the visibility of their personal profiles to only selected individuals.

To save you the hassle of searching for compatible users, Hitch.me shows you all of your matches with their professional and personal profiles on your own dashboard.

Although Hitch.me does not charge a monthly fee, credits are required to view personal profiles and send messages. Users receive 200 free credits upon signing up and 100 credits per each person that signs up by clicking on a shared link that users can post to their social networks.

Thereafter, credits cost $10 for 300, $25 for 1,000 and $50 for 2,500. Once you pay via credit card, a receipt is sent to your email and you obtain full access to browse professional and personal profiles and send messages.

Twenty credits are required to unlock a profile or send a smile, 50 to send a pitch and 100 to send a presentation.

”The intent is to keep Hitch.me professional and to make it as private and secure as possible,” says Nadir.

Hitch.me is self-funded and has officially launched Thursday.

iPhone Owners Have the Most Sex Partners [STUDY]

Dating site OkCupid has completed a study about its users’ smartphones and sexual history and has determined that among people who use smartphones, iPhone users have the most sexual partners, followed by BlackBerry users and finally Android users.

OkCupid looked at the data hidden in the images that users uploaded as profile pictures to see which cameras were used to take them — including smartphone cameras. With many of the site’s users also having taken personality tests like “The Dating Persona Test” or “The Slut Test,” which ask for a count of sexual partners, the site was able to cross-reference that data to complete the study.

The Origin of Twitter’s “Fail Whale”

If you’ve been on Twitter in the past month, you’ve probably bumped into the Fail Whale once or twice. The popular social network has been crashing pretty consistently from an influx of tweets and traffic. Seeing the whale, you (like everyone else) might have been frustrated — you might have yelled at the screen. You might hate that whale.

If you do, chances are you don’t know Yiying Lu or the story behind the Fail Whale, originally called “Lifting a Dreamer.” The whale (first drawn as an elephant) was created by Lu as a sweet greeting to her friends overseas. The minds at Twitter found it on iStockphoto and used the image as a 404 page (replacing a picture of a LOLcat).

The whale, once an image of Lu’s well-wishes, was supposed to represent the Twitter team’s effort to fix problems of scalability. Instead, the associations have largely been negative. Lu is hoping to turn that around even as she begrudgingly calls herself the “Fail Whale” designer.

Tricks to remembering names

“Everyone struggles with remembering names,” says Jill Spiegel, author of How to Talk to Anyone About Anything. “When we first meet someone we’re taking in so much visually and emotionally. They say their name, but it’s up there floating in our heads.” Making matters worse are all the single-syllable male names, like Chris, Mike or Tom, that tend to blend together.


HELEN COSTER, FORBES.COM

Few situations will make you cringe more than standing next to someone you’ve met several times and drawing a blank on his or her name.

Memory tips … Give your brain some clues to help you remember names.

Is it Joe or Jim? Sally or Susan? Here’s some help.

Plenty of business deals and romantic rendezvous have been foiled because someone failed to recall the right name at the right time. In the web age, e-mail and social networks offer safe harbour, so being able to use someone’s name (and pronounce it correctly) in a face-to-face situation can set you apart.
