איך החיידקים שולטים בנו ברוס גרמן, פרופסור לכימיה מאוניברסיטת קליפורניה דיוויס, חוקר זה יותר מעשור את אחת החידות הגדולות ביותר הקשורות בחלב האם: ההרכב המשונה שלו. 21% מהסוכר בחלב אם עשוי מחומר שאף תינוק אנושי אינו מסוגל לעכל. "במשך שנים האמינו שזו טעות אבולוציונית", אומר גרמן בראיון ל"מוסף כלכליסט". "אבל זה לא ייתכן. חלב אם עוצב על ידי 200 מיליון שנות אבולוציה, תחת אילוצים אדירים. הוא חייב להיות חסכוני מאוד, כי הוא עולה לאם באנרגיות אדירות, וכל רכיב בו אמור להיות מדויק על שבריר האחוז, משום שכל מחסור עלול להזיק לתינוק. 21% מבוזבזים פשוט לא מסתדרים עם זה". לגרמן היה רעיון. כמה שאלות נותרו פתוחות: האם החיידק הזה אכן נמצא בגופם של תינוקות? ד"ר ג'רמי קוניג, ביולוג מולקולרי מאוניברסיטת קורנל, הוא האיש היחיד בעולם שחקר באופן מדוקדק איך קהילת חיידקים צומחת מאפס לטריליון בגופם של תינוקות. עתה לגרמן נותר רק לגלות למה דווקא ביפידו. קצת אחרי שגילינו את האופטיקה, גילינו את החיידקים. מאז ועד לעשורים האחרונים ממש, המדע ראה בחיידקים את הביטוי הפרימיטיבי ביותר לחיים. בעשורים האחרונים התבררה גודלה של הטעות. אז מה עושים?

Ole's Home My name is Ole Laursen. I'm cofounder of IOLA where I work as a software developer. I have a Master's degree in computer science from Aalborg University in Denmark. More about my professional life at LinkedIn. I live in Aalborg, Denmark with my girlfriend Janne. As you can see from this page, my main interest is designing and programming software. Software Free software I'm maintaining: Flot - a jQuery plotting library for making attractive, pure client-side graphs. Old software Free software I'm more or less not maintaining anymore: The Django plugin django-rendertext - a simple library for generating images with small text snippets in a custom font in a Django web app. Even older software Free software I used to maintain before passing the bucket: gstream - a little C++ wrapper that allowed simple console-like <</>> output/input in standard Allegro graphics modes. I keep a list of good technical books. Notable other Ole Laursens include a kick boxer and a lawyer.

Google Begins Testing Its Augmented-Reality Glasses Photos via GoogleGoogle showed off its first venture into wearable computing, called Project Glass. If you venture into a coffee shop in the coming months and see someone with a pair of futuristic glasses that look like a prop from “Star Trek,” don’t worry. It’s probably just a Google employee testing the company’s new augmented-reality glasses. On Wednesday, Google gave people a clearer picture of its secret initiative called Project Glass. The glasses are not yet for sale. In a post shared on Google Plus, employees in the company laboratory known as Google X, including Babak Parviz, Steve Lee and Sebastian Thrun, asked people for input about the prototype of Project Glass. “We’re sharing this information now because we want to start a conversation and learn from your valuable input,” the three employees wrote. The prototype version Google showed off on Wednesday looked like a very polished and well-designed pair of wrap-around glasses with a clear display that sits above the eye.

Adam Westbrook: Want to be a Digital Storyteller? Just do it Do you want to tell digital stories that touch people? As a journalist, in marketing or education, or as a personal publishing project? I know that many people do, and that’s why I got quite excited about a beautiful digital book that I came across last week, Inside the Story. Not only that, all proceeds of the book go to Kiva, which empowers people around the world with micro loans. The whole thing was the idea of Adam Westbrook, a freelance multimedia producer who creates digital stories for commercial and non-profit organisations, and is also a lecturer and blogger based in London. Adam sent hundreds of emails over a period of months getting the best film-makers, journalists and designers to contribute. It was inspired by a project by Seth Godin – an ebook created collaboratively. I handpicked 24 of my favourite digital storytellers and asked them to each share one piece of hard-won advice. It’s been far more successful than I had imagined. The key word is authenticity.

How tech has helped me be a better dad It’s Father’s Day weekend, and many fellow dads out there may be looking for a good excuse to go out and buy some new gadgets. A new mobile phone maybe, a better camera or even a tablet. Go ahead, I say. My first daughter was born five years ago this month, and while there might be downsides to being an always connected father – I’m the first one to admit that checking email at the playground is a bad habit, but also that I do it nonetheless – there are also plenty of examples for technology saving the day, and memories for years to come. Is it time to freak out yet? Timing those contractions. Skype is for grandma. One of the many things my daughter wanted me to buy her. Let’s take a photo of it. Cloud to the rescue. The things my daughter does at preschool… sent to me via Posterous. Stay connected. Liked this story? And of course, feel free to share your favorite tech tips for dads in the comments.

Five Key TED Talks In 1833, Ralph Waldo Emerson, a New England pastor who’d recently given up the ministry, delivered his first public lecture in America. The talk was held in Boston, and its nebulous-sounding subject (“The Uses of Natural History,” a title that conceals its greatness well) helped lay the groundwork for the nineteenth-century philosophy of transcendentalism. It also changed Emerson’s life. In a world that regarded higher thought largely as a staid pursuit, Emerson was a vivid, entertaining speaker—he lived for laughter or spontaneous applause—and his talk that day marked the beginning of a long career behind the podium. Over the next year, he delivered seven talks, Robert D. Whether Emerson has a modern heir remains an open question, but, more than a century after his death, the speaking trade he enjoyed continues to thrive. Why? 1. 2. TED has always enjoyed a strong connection with Silicon Valley. 3. 4. 5. Illustration by Mr.
