NICE, Calif.--Over the last few days, I spent hours with my wife's parents, Tyler and Donna, helping them adapt to the first Internet connection they've ever had. For them, living on top of a mountain at 4,000 feet, in the middle of a national forest, and entirely off the grid--this has been a big step.

For my wife and I, it's also been a big project, at least in terms of teaching them the basics, and helping them get ready to learn on their own. While their Internet proficiency is still low, they are learning … Read more

Last year, the Institute for the Future created an alternate-reality game, Superstruct, designed to crowdsource scenarios to try to save humanity from fictional "superthreats" discovered in 2019 that are thought to mean the end of humanity by 2042.

Now, the IFTF has issued its first findings from the 1,000-plus stories, 500-plus discussions, and 500-plus "superstructures" created by the worldwide community of the game's players, and while there's some reason for hope, there's also a lot to be pessimistic about.

In a report issued Wednesday evening, Superstruct's program director, Kathi Vian, lead … Read more

While they're fascinating to watch and sometimes even delicious to eat, how many times a day do you really think about the octopus or what an amazing piece of natural machinery it is?

Cecilia Laschi, professor of industrial bioengineering at the Scuola Superiore Sant'Anna in Pisa, Italy, is so impressed by the octopus she's leading an extensive team of roboticists and scientists to build the first soft-bodied robot replicate of one. Which may not seem that exciting, until you learn just how unique the muscle tissue and dexterity of the octopus is.

As New Scientist cleverly pointed out, if the "Octopus" project is successful a robot someday might be able to accomplish the task seen in this video by Dr. James B. Wood, an assistant research scientist at the Bermuda Institute of Ocean Sciences who maintains a Web site on cephalopods.

If you think it through, the octopus is a very dexterous creature that if translated into a robot could provide endless capability for exploring hard to reach places in the ocean. While we've seen other aquatic robots reaching for the depths of the ocean or mimicking creatures like fish and snakes, a completely soft-bodied underwater robot would be groundbreaking.… Read more

AUSTIN, Texas--If there was one name that stood out on the agenda of speakers at the South by Southwest Interactive (SXSWi) festival here this week, it was famed FiveThirtyEight.com blogger Nate Silver.

Known as a statistical wunderkind, his models predicted the final outcome of the 2008 presidential election to within .4 percent of the final popular vote. But more important to many Democrats who had their hopes for electoral victory dashed by George W. Bush in 2000 and 2004, FiveThirtyEight.com--which got its name from the total number of electoral votes available--was able to provide daily affirmation that Barack Obama was really winning, even when many were tempted to believe he would be overcome by Sen. John McCain.

Silver was SXSWi's keynote speaker on Sunday, and he and interviewer Stephen Baker of Business Week went onstage in front of an audience of about 2,000 fans, most of whom were there to hear Silver talk about the secret sauce behind his hugely popular blog.

What many might not know is that Silver first came to prominence not in the political realm, but in baseball, where he authored Baseball Prospectus, a well-regarded baseball statistics site. Many might see the connection between baseball and politics as far-fetched, but to people like Silver, it's a very direct path.

Still, before starting FiveThirtyEight.com, he wasn't entirely a political neophyte. Silver had already begun to make a name for himself in the liberal political blogosphere with a series of data-rich posts on DailyKos. When he began to recognize some significant holes in the national polling establishment, he decided to step in to fill the void.

After his keynote interview, Silver sat down with CNET News and talked about the election, how his site got started, and more about the philosophical similarities between baseball and politics.

Q: Many Democrats were emotionally tied to what you were doing, in the sense that your data kept them calm during the election. Did your own numbers keep you calm? Nate Silver: Yeah, I think so. I'm just one of those people that likes to try and dissect a problem and once you started to dissect, some days you feel better about it. If I ever get cancer, the first thing I'll probably do is go on the Web and collect a bunch of data about different survival rates. I just feel better about things when I do them that way. It's a nerdy kind of thing to do.

Q: We were able to get up every day and look at the data and see what was going on. And this is not something you could do because it was your own data. How your own data affect how you felt about what was going on? Silver: I wouldn't be frustrated by it if McCain or Obama picked up points on a particular day. Sometimes you get frustrated if you know that something you did reveals something about your model. When something doesn't feel right, and you go and make changes. And we made a lot of changes over the course of the campaign where, even as recently as two weeks before the election, we were tweaking little parameters, and what started out as a pretty simple system--taking weighted averages of polls--became much more complex over time. But, yeah, we were never saying we had the perfect answer. We were always trying to improve things as we went along.

Q: The blog had an overt liberal position, but you always said the statistics were objective. What kind of feedback, if any, did you get from conservatives? Silver: We had a pretty good balance. We had probably about a 2-1 ratio in terms of liberal versus conservative readers, based on the comment threads. Now that we're not in an election, I think it's swung more toward the liberal side, both in terms of my writing and what people are reading about.

We try and be fair. That's the main thing, we try and be forthright. There's so much commentary from conservatives, also from liberals, that is just entirely disingenuous about certain things. It's a lot of cheerleading and cherry-picking of data. We're trying to present a case that by and large is a liberal's case, because it's my case. It's how I see the world. But we're trying to use data to do it where a lot of people just make bad arguments. … Read more

AUSTIN, Texas--If you wanted to see tesla coils rocking out, Dorkbot was the place to be Saturday evening at the South by Southwest (SXSW) conference here.

The local art collective Arc Attack had its singing tesla coils turned up loud and it put on several demonstrations of its machines at this celebration of "people doing strange things with electricity."

The highlight of the group's show was either a rendition of the "Dr. Who" theme or perhaps the Imperial march music from "Star Wars" (see video below--and give it a few seconds to get … Read more

When President Obama talks about employing technology to improve the health care system, perhaps he's talking about something like the kidney donation software developed by Silverstone Solutions.

Designed by software engineer David Jacobs--whose own brother died of kidney failure--Silverstone's Kidney Paired Donation technology is built around the idea of radically improving the process through which those in need of kidney transplants must go to get what they need. If they are able to at all.

Today, Jacobs said, there are 83,000 Americans waiting for kidney transplants, each of whom has to wait between seven and eleven years … Read more

A kerfuffle that exploded online in the past few days over who created the concept of a "bristlebot," a small robot mashed up with a toothbrush, looks like it has a happy ending after an agreement between a New York publisher and two Silicon Valley "makers."

The controversy arose when a forthcoming book called "The Invasion of the Bristlebots" was discovered at the recent New York Toy Fair, raising the hackles of many who were deeply familiar with the concept of bristlebots, which had first been spread in late 2007 by the Silicon Valley … Read more

When it comes to whimsy, there's no doubt that the concept of a "bristlebot," a combination robot and toothbrush, is dripping with it.

But there's little whimsy going on right now over a controversy that has arisen with the appearance at the recent Toy Fair in New York of a book from Klutz publishing called "Invasion of the Bristlebots."

That's because in December 2007, the inventors at Evil Mad Scientist posted a how-to entry on the Make blog about something they called "BristleBots," a combination of a robot and a toothbrush: … Read more

Starting this summer, some of the world's leading thinkers in exponentially growing technologies will be gathering annually at NASA Ames Research Center, in the heart of Silicon Valley, for 10 weeks of discussions on how to change the future. And you could join them.

The gatherings will be part of what is known as Singularity University, a brand-new academic institution co-founded by inventor and futurist Ray Kurzweil, X Prize chairman and CEO Peter Diamandis, and former Yahoo Brickhouse head Salim Ismail, and anyone can apply.

Singularity University is less a traditional university and more an institution that will feature … Read more
