TORONTO -- Commercial director Joseph Kosinski is in final negotiations to develop and direct "Tron," described as "the next chapter" of Disney's 1982 cult classic. Sean Bailey is producing via the Live Planet banner, as is Steven Lisberger, who co-wrote and directed the original film.Imagine being able to download the three-dimensional plans for your child's favorite toy, then pressing Print — and out comes not a picture, but the toy itself. That's the idea behind Desktop Factory, a 3-D printer that melts a mixture of nylon, aluminum and glass into durable (albeit small) objects. The technology is still in its infancy, but it's the first of its kind to be marketed to individual consumers.
At first glance, Morpho Towers may seem static — two metal spirals lounging lazily on a plate resting in a magnetic liquid saturated with iron particles. But crank up your stereo and prepare to be dazzled: The ferrofluid will creep up the towers, forming a viscous, organic sculpture that grooves to the tunes and forms a stunning variety of shapes. Heavy metal will never be the same.
1933: Physicist Leo Szilard gets the nuclear age rolling, so to speak, by conceiving the idea of a nuclear chain reaction while standing at a red light.
Szilard, a native of Budapest and a soldier in the Austro-Hungarian army during World War I, left Hungary for Germany to escape the postwar rise of anti-Semitism. Originally an engineering student, he switched to physics after moving to Berlin and studied under Albert Einstein, among others.
His decade in Berlin was fruitful and Slizard was engaged in a number of projects, including development of the linear accelerator, cyclotron and home refrigeration. But with the rise of the Nazis, Slizard found himself on the move again, this time to London.
Not long after his arrival, Slizard read an article in the Times of London rejecting the idea of any practical use for atomic energy. So incensed was Slizard, the story goes, that he stood right there at a traffic signal in Bloomsbury and dreamed up the nuclear chain reaction. A year later he patented the concept.
His early attempts at triggering a reaction, however, failed. He tried using beryllium and indium to no effect and, in 1936, he assigned his chain-reaction patent to the British Admiralty to ensure secrecy. Soon thereafter, Slizard accepted a teaching post at Columbia University in New York, and moved to the United States.
There, he met Enrico Fermi and, reacting to the discovery of nuclear fission in a Berlin laboratory, the two men realized uranium was the agent they needed to produce their reaction. Working at the University of Chicago, they produced the world's first controlled nuclear chain reaction in December 1942.
Apple started selling iPhone ringtones for $2 apiece through its iTunes store last week, but if you aren't afraid of a little tinkering, you can get that "Hey Ya" or "Sexy Back" ringtone without shelling out the extra bucks.
Users have to pay Apple $1 for a song, plus an extra $1 to convert that song into a ringtone. Of course, hackers immediately set out to find a way to generate iPhone ringtones for free. In a classic game of cat and mouse, Apple has spent the last few days trying to block iPhone owners from installing free ringtones on their devices -- only to watch hackers come up with workarounds just hours after each patch is released.
Apple has continued to update its iTunes software (which syncs with the iPhone to add ringtones) to block the specific loopholes uncovered by the hackers. In fact, iTunes was updated almost immediately after the first loophole was uncovered Friday.
Despite Apple's best efforts, the chase continues. The most-popular desktop applications for installing custom ringtones were updated this weekend, in one case only hours after Apple updated its software to block them.
Mac users can rely on applications like iToner ($15 from Ambrosia Software), which is a full-featured ringtone manager for the iPhone. Windows users can get similar functionality from iPhoneRingtoneMaker ($15 from Efiko Software).
These options feature drag-and-drop ringtone management, including the ability to use just about any sound file and the option to set specific songs to play when specific people call. The latest iTunes update appears to have crippled iPhoneRingtoneMaker for some users, but the developers at Efiko are working on the problem. IToner is currently up to date.

To solve that problem, MIT researchers have developed a new polymer for gene therapy that is as effective as viruses, the standard carriers, but it seems to have none of the risks of viral treatments. The researchers have successfully tested a version of the polymer in mice with ovarian cancer, and they believe they can further modify the polymer to target virtually any cell in the body.
Gene therapy works by delivering to a specific group of diseased cells copies of a gene that corrects what ails them. "If you could get it [a gene] where it's needed, you could treat many diseases," says the MIT Center for Cancer Research's Daniel Anderson, one of the leaders of the polymer research group.
