IBM imagines a computer that smells your illness

For the past several years, IBM's research arm has been making predictions about emerging technologies that will change our lives over the next five years. Dubbed "5 in 5," the annual year-end list has already accurately predicted the rise of now-familiar cultural touchstones like Siri, as well as our reliance on smartphones for everything, and real-time speech translation.

This year, IBM has taken a more in-your-face approach to predicting the future of innovation, by specifically focusing on, well, the face and the five senses that make their home there (and yes, hands and everywhere else in the case of touch).… Read more

IBM research honcho: From the Pentagon to the 'toy shop' (Q&A)

Since September 11, 2001, the American security apparatus has been focused largely on stopping terrorists from striking again. But some feel a more pressing danger may be that of cyber attacks, digital hacks that disable critical infrastructure and bring society to a crawl.

As the U.S. government has tried to shape its approach to such attacks, President Obama and the secretary of defense have relied on contributions from a number of people in the Pentagon and elsewhere for ideas on how to stop bad actors, be they from national governments or small terrorist groups. Among them was Assistant Secretary … Read more

IBM pushes silicon photonics with on-chip optics

IBM has advanced the technology of silicon photonics, fabricating a microchip that has built-in components to send and receive data over optical links.

Researchers have built optical data links into chips before, but IBM's move is notable because it uses conventional chipmaking equipment geared for chips with 90-nanometer features. Today's chips use metal wires to exchange data, but optical links offer the potential of higher transfer speeds over longer distances.

The chip can include several optical components including wavelength division multiplexers that let the chip send and receive signals with multiple frequencies of light, an approach that lets … Read more

My Best Tech Gift Ever: A 133MHz IBM PC 350

Every day this week, a different CNET writer or editor is recalling a tech or geek-centric present that left a mark. Read past stories by Eric Mack, Jeff Sparkman, Jay Greene, and Dan Ackerman, and look for another installment tomorrow at midnight PT.

On a chilly autumn day in 1997, I came home from school to find that my mom had a brand-new IBM PC 350 in her office. It was an astonishing computer, especially considering our previous machine was a DOS/Windows 3.1 slowpoke that could barely run Wolfenstein 3D.

For its time, the PC 350 had it all -- a screaming Pentium 133MHz processor, a 1.6GB hard drive, 64MB of RAM, and 4MB of video memory. Though my mom bought it for the household and not for me exclusively, it was the best tech gift I ever got, as it truly turned me into a geek and gamer (and therefore the person I am today). … Read more

Cyber Monday crowned biggest Web shopping day in U.S. history

Cyber Monday this year took the trophy for the biggest online shopping day ever in the U.S.

ComScore reported that U.S. online spending on Cyber Monday 2012 reached $1.465 billion, up 17 percent from a year ago, "representing the heaviest online spending day in [U.S.] history and the second day this season (in addition to Black Friday) to surpass $1 billion in sales."

Breaking the total down, ComScore said that the top category for sales was digital content and subscriptions (up 28 percent), followed by consumer electronics (up 24 percent and "buoyed by … Read more

Titan steals No. 1 spot on Top500 supercomputer list

Predictions that Oak Ridge National Laboratory's Titan supercomputer had become the most powerful machine in the world have turned out to be right.

The machine, powered by Nvidia graphics processors and Advanced Micro Devices computer chips, stole the No. 1 spot on the Top500's list from another U.S. machine, Lawrence Livermore National Laboratory's Sequoia.

Sequoia, which uses processors from IBM, became the top computer in June with a performance of 16.32 petaflops a second. Titan beat that showing, sending Sequoia to second place on the list, with a result of 17.59 petaflops per second. … Read more

IBM brings carbon nanotube-based computers a step closer

In the effort to find a replacement for today's silicon chips, IBM researchers have pushed carbon nanotube technology a significant step ahead.

Carbon nanotubes are very small structures made of a lattice of carbon atoms rolled into a cylindrical shape, and a team of eight researchers have figured out a way to precisely place them on a computer chip, IBM announced today. That development allows them to arrange the nanotubes 100 times more densely than earlier methods, a key step in economical chipmaking, and IBM has built a chip with more than 10,000 carbon nanotube-based elements.

The new … Read more

Apple scores as second best global brand in new report

Apple is the second best brand in the world, according to market research firm Interbrand.

Among the 100 best global brands for the year, Apple came in just behind top-seated Coca-Cola. Based on specific factors, Coca-Cola scored a total brand value of $77.8 million, while Apple was given a value of $76.5 million.

In ascending to second place, Apple saw a 129 percent rise in its brand value since last year, the largest gain among all the brands on the list.

How does Interbrand choose which brands it considers best?

The research firm uses three factors: 1) the … Read more

Did a bug in Deep Blue lead to Kasparov's defeat?

It's part of the conventional wisdom now that machines are smarter than us, especially when it comes to specific challenges. Chess, for instance. World champion Garry Kasparov's defeat at the hands of IBM's Deep Blue computer in 1997 was a milestone in the story of artificial intelligence.

But did the machine merely psych him out? Statistician Nate Silver's new book "The Signal and The Noise: Why So Many Predictions Fail--But Some Don't" contains an anecdote about how a glitch in Deep Blue may have led Kasparov to overestimate the machine's smarts, according to The Washington Post.

Despite the machine's ability to evaluate 200 million moves per second, Kasparov easily won the first game of the match. In the 44th move, however, Deep Blue made an inexplicable play, moving a rook for no apparent purpose. … Read more
