An issue that periodically makes its way into public discourse -- the impact and possible dangers to brain development and health posed by the ubiquitous use of cellphones -- is being revisited thanks to a newly published scientific study in JAMA. However, rather than offering any definitive answer...
Lasers amplify light. The name itself is an acronym for "Light Amplification by Stimulated Emission of Radiation." It's only natural then that the world's first anti-laser cancels light, and could spark applications in optical supercomputing and radiation oncology. "Our device is a laser that works ...
Science fiction enthusiasts could probably connect over plans Microsoft announced Monday for Kinect, the company's interactive gaming add-on for the Xbox 360. A software developers kit is on the way, Microsoft representatives told journalists at a sneak-peek event that featured a Kinect digital ren...
Cold fusion -- the largely discredited science of making more energy from less -- may be making a comeback. Controversial yet high-profile demonstrations in Italy last month purported to show a cold fusion device turning 400 watts of heat power into 12,400 watts. The eye-popping 31-fold "excess hea...
One of the sad rumors to break last week was that Steve Jobs may have six weeks to live. I've had several people close to me die of cancer. One stepmother was given a few months, but she actually lived more than a year and did a number of amazing things. Another stepmother died two days after the i...
Security guards at the 2011 RSA conference in San Francisco on Friday had a little surprise in store for reporters queuing up to attend former President Bill Clinton's keynote speech. Journalists were asked to leave the queue, which had begun forming shortly after 11 a.m. for a speech originally sch...
Twenty years from now, semiconductor chips will cost a penny apiece and will be in everything -- our clothing, our sunglasses, our contact lenses and even our toilets -- physicist Michio Kaku told an audience Thursday at the RSA 2011 convention. They'll revolutionize warfare, manufacturing and the m...
Fresh from a super-sized "Jeopardy" victory where it looked suspiciously like President Obama's ubiquitous teleprompter, IBM supercomputer Watson is about to become Dr. Watson, M.D. assistant. A joint venture will combine IBM's question-answering, language-processing, and machine-learning capabilit...
As IBM celebrates its centennial this year, the company is building technologies to take us into the future. IBM's Watson computer has pounded its human opponents on the game show "Jeopardy," signaling huge improvements in the development of artificial intelligence and cognitive computing. Meanwhile...
Three solar flares will hit the Earth Thursday and Friday, according to scientists, possibly triggering a bigger show of the Aurora Borealis, also known as the northern lights. They may also impact the Earth's magnetic field to some degree, depending on the direction of the magnetic field accompanyi...
Ten-4. Back to you. Over. On a radio or over the TV airwaves, speakers have to rely on back-and-forth communications because radio traffic only flows in one direction at a time on a frequency. Or so said scientific conventional wisdom, until Stanford researchers developed so-called "full duplex" r...
Nurdles. Aglets. Bakelite. Cellophane. There's poetry in the myriad names of plastic, which seems fitting for a man-made substance that barely existed prior to World War II but will most likely outlast human civilization itself. And that's just the 100 billion tons of the stuff we've created so f...
Instantly sorting 15 trillion memory bytes to find the right answer to a "Jeopardy" question: Elementary, my dear Watson. Or so an IBM supercomputer named "Watson" set out to prove Monday, tackling trivia with the popular television game show's all-time human champs, Brad Rutter and Ken Jennings. "...
"Big screen, middle screen, little screen," might be a fast way to describe the journey of 3D technology, the last leg of which LG unveiled Monday at the Mobile World Congress. The world's first three-dimensional smartphone, LG's Optimus 3D runs the Android operating system on a 4.3-inch LCD glasses...
I'm writing this at the IE9 launch, which happened last Thursday, and this morning I had an epiphany. Don't worry -- I'm pretty sure my meds will kick in momentarily, but until they do, it strikes me that with all the focus on innovation and Apple, Apple doesn't really innovate that much. What it d...
