Science has confirmed that the trusty mobile gadget - which now comes as a smartphone or feature phone - emits radiation, ramping up fears that humans may indeed develop brain cancer from excessive use of the ubiquitous device.
In May 2011, the World Health Organisation (WHO) listed cell phones as likely contributors to brain cancer, specifically glioma and acoustic neuroma brain conditions.
My editor, Selena Frye called, asking what I knew about quantum cryptography. I remember muttering something about qubits. “Good,” she said. “This Phys.org article discusses a problem that has been fixed, I’d like you to write about it?”
“Sure, I’ll get right on it. I didn’t even know quantum cryptography was broken. And, they already have a fix.
U.S. researchers say a prototype firewall can keep hackers from interfering with wireless medical devices such as pacemakers and insulin-delivery systems.
A team of scientists from Purdue and Princeton universities had previously demonstrated how medical devices could be hacked, potentially leading to catastrophic consequences.
An expert said devices like heart monitors and insulin pumps could easily be used to kill their host, with would-be attackers having greater access to them than ever before, the BBC reports.
Professional hacker Barnaby Jack, who works for computer security company McAfee Inc, was able to hijack a well-known insulin pump by hacking its radio signal within just two weeks.
Imagine sitting down at your keyboard, typing in your user name and starting work right away - no password needed. That's precisely what Richard Guidorizzi, program manager at DARPA hopes to one day achieve.
Artificial intelligence researchers have constantly been seeking to make computers more like us with the ability to learn, hypothesise and make decisions. In the past, AI researchers have involved adults, but are now looking elsewhere for inspiration - the brain of a human child.
While the Search For Extra Terrestrial Life (SETI) may not be quite as flush as it used to be, its organizers are finding new and interesting ways to continue the search for life among the stars. Their latest initiative is SETILive, a crowd-sourced web application that lets anyone join the search of the nearby universe, no advanced degrees required. The SETILive website allows registered users to scan automatically-generated images based on radio frequency scans of sections of space that SETI believes are the likeliest to contain extraterrestrial life.
A laptop stolen from NASA last year contained command codes used to control the International Space Station, an internal investigation has found.
The laptop, which was not encrypted, was among dozens of mobile devices lost or stolen in recent years that contained sensitive information, the space agency's inspector general told Congress today in testimony highlighting NASA's security challenges.
IBM Research scientists said they have achieved a major advance in quantum computing that will allow engineers to begin work on creating a full-scale quantum computer.
The breakthrough allowed scientists to reduce data error rates in elementary computations while maintaining the integrity of quantum mechanical properties in quantum bits of data, known as qubits.
It’s been slow going for the world’s first commercial passenger space program, but Virgin Galactic is slowly but surely making progress.
While it’s already gotten its SpaceShipTwo sub-orbital craft beyond the reaches of Earth’s atmosphere in successful tests before, it only did so with the help of a carrier vehicle, then glided back to earth and landed conventionally. The company hopes to install and test the craft’s rocket engine before the end of 2012, marking a major milestone in Virgin Galactic’s plans to create a space tourism business.
