Apple is teaming up with former nemesis IBM to work together on about 100 different mobile applications in an attempt to sell more iPhones and iPads to corporate customers and government agencies. The applications, expected to be released this fall, will feature some of data-crunching tools that IBM Corp. sells to companies trying to get a better grasp on their main markets while scouring for new money-making opportunities.
The doubling of transistors on a microprocessor occurs roughly every two years, and is the outcome of what is called Moore’s Law. In a bid to continue this trend of decreasing transistor size and increasing computation and energy efficiency, chip-maker Intel has partnered with Lawrence Berkeley National Laboratory to design an entirely new kind of photoresist, one that combines the best features of two existing types of resist.
Firms buy specific keywords, including competitors’ brand names, on search engines such as Google or Bing to reach consumers searching for those words. Online advertisements employing such keywords are called search ads. This practice can backfire, however. A new study shows that any large difference in reputation between the two brand names is further magnified in the minds of consumers.
An Android update, wearable gadgets, and so-called smart home devices are just some of the innovations Google is likely to show off at its two-day developer conference, which begins today in San Francisco. In recent years, the conference has focused on smartphones and tablets, but this year Google's Android operating system is expected to stretch into cars, homes, and smartwatches.
New robot guides at a Tokyo museum look so eerily human and speak so smoothly they almost outdo people. The two life-size robots, which have silicon skin, artificial muscles, and can speak in a variety of voices, will be on display starting Wednesday, allowing the public to interact with them extensively.
At the 2014 Symposium on VLSI Technology in Triangle Park, N.C., researchers from the Univ. of California, Santa Barbara introduced the highest-performing class III-V metal-oxide semiconductor field-effect transistors (MOSFETs) yet demonstrated. The new MOSFETs exhibit, in an industry first, on-current, off-current and operating voltage comparable to or exceeding production silicon devices, while also staying relatively compact.
A cooing, gesturing humanoid on wheels that can decipher emotions has been unveiled in Japan by billionaire Masayoshi Son, who says robots should be tender and make people smile. The machine, called “Pepper”, has no legs, but has gently gesticulating hands. It recently appeared on a stage in a Tokyo suburb along with announcement that it will go on sale in Japan next year for the equivalent of US$1,900.
The need for robust password security has never been more critical than now, as people use smartphones or tablets to pay bills and store personal information. A new Rutgers study shows that free-form gestures can be used to unlock phones and grant access to apps. These gestures are less likely to be observed and reproduced than than traditional methods such as typed passwords.
Highlighting the impact of malicious software, Target suffered the largest retail hack in U.S. history during the Christmas shopping season of 2013. To help combat this worsening trend, Virginia Tech computer scientists have used causal relations to determine whether or not network activities have justifiable and legitimate causes to occur. The work effectively isolates infected computer hosts and detects in advance stealthy malware.
New tools for tracking health and controlling household appliances are part of updated operating systems that Apple unveiled Monday in San Francisco at its 25th annual conference for application developers. The company is expanding into home and health management as the company tries to turn its iPhones, iPads and Mac computers into an interchangeable network of devices that serve as a hub of people's increasingly digital lives.
Web services companies make promises about how they will use personal information. But ensuring that millions of lines of code operate in ways consistent with privacy promises is difficult. A team from Carnegie Mellon Univ.and Microsoft Research has shown, however, that these compliance checks can be automated. Their prototype automated system is now running on the data analytics pipeline of Bing, Microsoft's search engine.
Researchers in Australia have created a micrometer thin film with record-breaking optical nonlinearity suitable for high-performance integrated photonic devices. To create the thin film the researchers spin coated graphene oxide solution to a glass surface. Using a laser as a pen they created microstructures on the graphene oxide film to tune the nonlinearity of the material.
Alibaba, the e-commerce giant planning a blockbuster share sale in the U.S., shook up China's vast but sleepy retailing industry by popularizing online shopping. Now it and China's other Internet companies are mounting challenges in areas from banking to broadcasting. The new wave of change was triggered by the abrupt shift of Chinese Internet users to surfing the Web via smartphones or tablets.
First proposed for memory in the 1970s, phase-change materials exhibit two metastable states which can store data when placed between two electrically conducting electrodes. IBM researchers in Zurich have recently used them as part of Project Theseus to develop a PCI-e card that melds flash memory with phase-change memory. The major improvement in speed interests IBM for Big Data applications.
