Watch This Remarkable Teenager Come Out to Her Whole School on MLK Day - Culture - GOOD Kayla Kearney is a senior at Maria Carrillo High School in Santa Rosa, California. She's also a lesbian, a secret she kept from her friends and family her whole life. But at a school assembly honoring Martin Luther King Jr. earlier this month, that all changed. Prior to the assembly, Kearney asked a teacher if, rather than singing a song or performing a dance routine like her classmates, she could give a speech. What followed is the video above, Kearney's heartfelt, poised, and elegant address in which she comes out as gay and tells her classmates that it's time to "break the silence" of all LGBT youth. "Facing this reality was the most challenging thing I've ever had to do in my entire life," says Kearney, "simply because I knew that for the rest of my life I was going to face a world that told me I was wrong."

Area Mapping Tool "Discovery of Alien Life in Next 10 Years" --One of Five 'X Factors' According to World's Leaders The "X factors" are described in the reports as factors that "no country alone can prevent," and illustrates the notion of an "X factor" as an "unheralded" event that may suddenly confront humanity. Among the five "X factors" identified was “Discovery of Alien Life." "Given the pace of space exploration, it is increasingly conceivable that we may discover the existence of alien life or other planets that could support human life," said the WEF. "What would be the effects on science funding flows and humanity’s self-image?" WEF.org observed that "It was only in 1995 that we first found evidence that other stars also have planets orbiting them. Among the other X Factors: "Neuroscientists, for instance, are avidly pursuing drugs and devices that could deliver real cognitive enhancement — not just sharpening our alertness and ability to focus, as certain drugs already do, but upping our intellectual firepower.

The World’s First Vertical Forest: An I’d like to introduce you to the world’s first Bosco Verticale (Italian for Vertical Forest), which is being built right now in Milan. According to Christopher Woodward, a writer for the Financial Times, it’s “the most exciting new tower in the world.” This vertical forest will span across two towers that have fabulous balconies designed to house these trees. This forest, designed by architect Stefano Boeri, will allow the greenery to get shade in the summer, sunlight in the winder and protection from the wind while it cleans the air, produces oxygen and cuts down on all the noise pollution in Milan.

How Chocolate Might Save The Planet : Krulwich Wonders... When you unwrap it, break off a piece and stick it in your mouth, it doesn't remind you of the pyramids, a suspension bridge or a skyscraper; but chocolate, says materials scientist Mark Miodownik, "is one of our greatest engineering creations." True, it begins with a cocoa bean plucked from a tree. But no one would eat a raw cocoa bean. "It tastes revolting," Miodownik says in his new book, Stuff Matters. Robert Krulwich/NPR But cut it, leave it, roast it, tinker with it for a couple of centuries (and add sugar) ... ... and cocoa beans can be totally transformed. Chocolate's Secret Chocolate bars have a circus trick, an "Oh, my" moment: They're solid when you unwrap them. The secret ingredient is cocoa butter, stored in the form of large molecules called triglycerides that come with three (thus the "tri") prongs. ... or more tightly, like this ... ... or ( I'm redrawing this from Mark's book) more richly intermeshed, like this: The denser the package, the harder the chocolate.
