18 Today At a conference about ideas, it’s important to step back and consider the engine that creates them: the human mind. How exactly does the brain -- a three-pound snarl of electrochemically frantic nervous tissue -- create inspired inventions, the feeling of hunger, the experience of beauty, or the sense of self -- and how reliable is it? Dan Dennett contemplates the mind as an ecosystem in which a new class of entities -- memes -- can compete, coexist, reproduce and flourish, and asks what sorts of nefarious things these entities might be up to. An enthusiastic Dan Gilbert presents his new research on the peculiar, counterintuitive -- and perhaps a smidge deflating -- secret to happiness. And Jeff Hawkins explains why a napkin-sized sheaf of cellular matter, wrinkled into a ball, will fundamentally change the direction of the computer industry.

MAKE is a quarterly publication from O'Reilly for those who just can't stop tinkering, disassembling, re-creating, and inventing cool new uses for the technology in our lives. It's the first do-it-yourself magazine dedicated to the incorrigible and chronically incurable technology enthusiast in all of us. MAKE celebrates your right to tweak, hack, and bend technology any way you want.

High definition views of Chandra's exciting science Cassiopeia A is the 300-year-old remnant created by the supernova explosion of a massive star. Each Great Observatory image highlights different characteristics of the remnant.
10 Today The environmental debate has traditionally been characterized as a conflict between economic progress and preservation of the planet. Most TED speakers, however, insist that we can have both -- provided we're smart about it. Al Gore, the world's leading voice on the climate crisis, argues that the simple steps we might take to avert disaster would also fuel the economy. Architect William McDonough shows how the power of great design -- working on entire systems rather than local components -- can foster an abundant, sustainable future. And Majora Carter discusses her work to bring green spaces to the blighted South Bronx. Edward Burtynsky's eerily pretty photographs of environmental damage and economic development document humanity's ever-expanding footprint. And biologist E.O. Wilson shares his grandest wish -- that the human community band together to save life on Earth.

7 Today "The Pursuit of Happiness" was 2004's conference theme, but TED speakers over many years have found themselves driven to understand the nature of happiness. Daniel Gilbert's astonishing talk shows how we humans are poor predictors of what will make us happy. Stefan Sagmeister shares how great design contributed to his happiest moments, suggesting that the secret may be attention to detail. And Malcolm Gladwell, tongue in cheek, explores what we might learn about the pursuit of happiness through one man's quest to make the perfect pasta sauce. But suppose we understand happiness. How, then, do we find it? Carl Honore says the key is, simply, to slow down. Pastor Rick Warren appeals for a life of spiritual purpose. And Barry Schwartz thinks a little less choice might do us all a lot of good.
7 Today The contemplation and, often, introduction of new technology is integral to TED: you might say it's embedded in our genetic code. Computer scientist Jeff Han intends to reinvent computing by replacing traditional point-click user interfaces with dynamic touch screens. Robert Full wants to enhance transit and robotics by studying the motion of animals whose system of locomotion can adapt to nearly any surface. And Juan Enriquez discusses oil energy -- derived, ultimately, from ancient plants -- and wonders why we can't develop methods to "grow" energy as efficiently as we grow wheat. Blaise Aguera y Arcas demonstrates his powerful new software, Photosynth, which fuses digital photographs from unrelated sources into fluid, three-dimensional tapestries of real environments. Alan Russell wants to use bioengineered tissue to regenerate damaged body parts. And Chris Anderson of WIRED discusses how emerging technologies -- matched with the right business model -- can make an impact of perhaps surprising magnitude.

Inspired by the real-life forensic anthropologist and best-selling novelist Kathy Reichs, Bones is a darkly amusing investigative drama centered on Dr. Temperance Brennan, a forensic anthropologist who writes novels on the side. She and FBI Special Agent Seelely Booth take on murder cases that defy the standard methods of identifying a body, requiring Brennan to use her uncanny ability to read clues in victims' bones.
