Computer scientists from the University of California, San Diego broke "the terabyte barrier" -- and a world record -- when they sorted more than one terabyte of data (1,000 gigabytes or 1 million megabytes) in just 60 seconds. During this 2010 "Sort Benchmark" competition -- the "World Cup of data…

Touch screens such as those found on the iPhone or iPad are the latest form of technology allowing interaction with smart phones, computers and other devices. However, scientists in Germany have developed the next generation non-contact gesture and finger recognition system. The novel system detects hand and finger positions in…

Researchers are using computers to identify how one strain of dangerous bacteria might mutate in the same way a champion chess player tries to anticipate an opponent's strategies. The predictive software could result in better drug design to beat antibiotic-resistant mutations.

Researchers in Spain have developed a tool that simplifies the use of the semantic web. The new tool, called Fortunata, can be used by developers, graphic designers and end users without an in-depth knowledge of informatics.

Advanced imaging technologies that promise to improve effective drug development to treat lung cancer are the focus of the current issue of Optics Express. Research outlines standardized approaches to measure and compare tumor size, as well as to validate the accuracy of such measurements. This validation is a critical new…

Large-scale computer hosting infrastructures offer a variety of services to computer users, including cloud. But when these infrastructures run into problems -- like bottlenecks that slow their operating speed -- it can be costly for both the infrastructure provider and the user. New research will allow these infrastructure providers to…

Playing computer games could get a lot more lifelike, thanks to a major research project being carried out in the UK.

Computer scientists have developed a rapid and effective approach to produce vaccines for new strains of influenza viruses. The researchers hope to develop the new technology and provide an efficient method to confront the threat of seasonal epidemics.

A new computer data compression technique called Genomic SQueeZ will allow genetic researchers and others to store, analyze and share massive volumes of data in less space and at lower cost.

Every picture tells a story, but how do you know that a digital photo has not been manipulated to change the tale being told? A new approach to adding an encrypted watermark to digital images allows the an image to be validated against a pass key, according to new research.

Personal computers in enterprise environments save energy and money by "sleep-working," thanks to new software called SleepServer. Sleep-working enterprise PCs are accessible via remote connections and maintain their presence on voice over IP, instant messaging, and peer-to-peer networks even though the PCs are in low-power sleep mode. SleepServer can reduce…

A searchable directory of the countless biological databases on the web produced in the wake of genomic and post-genomic research could be generated automatically, according to new research.

Researchers have developed a computer program capable of identifying language that can indicate a writer's psychological state, which could serve as a screening tool. The software was used to scan more than 300,000 English language blogs that were posted to mental health Web sites. The program identified what it perceived…

3G and Wi-Fi are the two main mobile communications technologies today, but until recently they have been complementary services, the former offering users network access through cellphone masts forming a wide-area network (WAN), the latter based on hot-spot connections through a local-area network (LAN). Both then provide connectivity to the…

Around the country and throughout the world, politicians and education activists have sought to eliminate the "digital divide" by guaranteeing universal access to home computers, and in some cases to high-speed Internet service. However, according to a new study, these efforts would actually widen the achievement gap in math and…
