Submission + - Learn Coding Online (

JoeMerchant writes: Online services like CodeCademy and Treehouse are making a business of teaching programming online. Despite the fact colleges are churning out more programmers, many fast-growing Silicon Valley companies say they still can't find enough of them.

Do you think that the online schools will add anything to traditional self-teaching of programming skills?


Submission + - 17yr old creates cancer-killing nanoparticle (

An anonymous reader writes: Angela Zhang has just been awarded the $100,000 Grand Prize in the Individual category of the Siemens Competition in Math, Science & Technology. Her project was entitled “Design of Image-guided, Photo-thermal Controlled Drug Releasing Multifunctional Nanosystem for the Treatment of Cancer Stem Cells.”

Her creation is being heralded as a “Swiss army knife of cancer treatment.” Zhang managed to develop a nanoparticle that can be delivered to the site of a tumor through the drug salinomycin. Once there it kills the cancer stem cells. However, Zhang went further and included both gold and iron-oxide components, which allow for non-invasive imaging of the site through MRI and Photoacoustics.


Submission + - Flash Obsoleted by IBM Breakthrough in PCM (

An anonymous reader writes: IBM claims to have refined phase change memory (PCM) to put it on track to replace flash within three years. PCMs will be 100-times faster, last 3000 times longer and achieve densities that make flash look like an antique. We've heard these claims before, but this time it looks like they've got the deep-pockets and architectural changes to make it work.
