The U.S. Bureau of Labor Statistics (BLS) reports that few students are enrolling in computer science courses, particularly women and minorities. The BLS ranks computer application software engineering as the fourth most in-demand occupation in its Occupational Handbook for 2006-2016, largely because of the growing number of applications for emerging technologies and the increasing complexity of businesses. However, the National Science Foundation’s (NSF’s) Jan Cuny says there has been a major drop-off in the number of computer scientists entering the workforce since 2000. Since 2000, 70 percent fewer students have majored in computer science, with 80 percent fewer women entering the field, according to Computing Research Association data. Cuny says the Higher Education Research Institute reports that only 1 percent of students are majoring in computer science, and just 0.3 percent are women. University of North Carolina (UNC) at Greensboro professor Anthony Chow says that over the past eight years there has been a slight increase in women’s enrollment in computer science at the undergraduate level, but on the graduate level minority enrollment plunges to extremely small percentages. Retaining minority employees is another major problem, with nearly half of all minorities leaving technology jobs to enter other occupations, according to the National Association for the Advancement of Colored People. Isolation is a major factor in the drop-out rates for women and minorities, says Teresa Dahlberg, director of the Diversity in Information Technology Institute at UNC Charlotte. She also says that women are often judged more harshly than men. Cuny says NSF is focusing on information education programs intended to spark student interest in computing by demonstrating how computers can solve programs through creativity, and also is working to infuse computer science into middle school and high school curricula.

The World Wide Web Consortium has published File API, an interface draft that Web browsers can use to better manipulate files and is part of a larger effort to provide a better foundation for interactive applications. File API defines ways browsers and Web sites can improve how they handle files, including selecting multiple files for upload, such as on photo-sharing sites or Web-based email. Other improvements govern the use of “blobs,” or packages of raw binary data such as video files. Google has supported blobs for its Gears browser plug-in as a way to separate large videos into smaller pieces so uploads can be more easily resumed if a network problem interrupts the process. A major benefit is that files are handled asynchronously, meaning the browser will not freeze while a file is being uploaded or managed, and the browser reports back on the progress of file transfers. The interface is compatible with several standards, including the drag-and-drop support in HTML5, currently in development, and the Web Workers technology that improves the way browsers perform numerous operations simultaneously. The interface also can help Web applications process and understand the contents of files. For example, the interface could allow for Web applications that automatically search through a music playlist and find the lyrics to the songs on that playlist.

Recent advancements in supercomputer design coupled with falling prices are breaking down the barriers that have traditionally surrounded computing-intensive research, which could give ordinary users with a novel idea the opportunity to explore its potential using powerful computers. Ninety percent of the world’s 500 fastest computers use standard microprocessors, which enable supercomputers to be built much more inexpensively. “I think this says that supercomputing technology is affordable,” says Advanced Micro Devices director Margaret Lewis. “We are kind of getting away from this ivory tower.” This possibility has inspired some of the world’s top computing experts to make valuable sources of information available, with the goal of filling supercomputers with scientific data and allowing anyone in the world with a PC to access these systems. “It’s a good call to arms,” says Silicon Graphics’ Mark Barrenechea. “The technology is there. The need is there. This could exponentially increase the amount of science done across the globe.” Sharing data and supercomputing resources could allow labs to accomplish far more than was previously possible. Argonne Leadership Computing Facility director Pete Beckman says shifting science research into the cloud democratizes science. Argonne, with funding from the U.S. Department of Energy, is working on Magellan, a project to explore the creation of a cloud-computing infrastructure that scientists around the world could use. Beckman says such a system would reduce the need for smaller universities and labs to spend money on their own computing infrastructure.

University of Arkansas researchers have developed a new method for preventing the cloning of passive radio frequency identification (RFID) tags. The method prevents the production of counterfeit tags by focusing on one or more unique physical attributes of individual tags, instead of the information stored on the tags. “It is easy to clone an RFID tag by copying the contents of its memory and applying them to a new, counterfeit tag, which can then be attached to a counterfeit product–or person, in the case of these new e-passports,” says Arkansas professor Dale R. Thompson. “What we’ve developed is an electronic fingerprinting system to prevent this from happening.” The researchers determined that all RFID tags have a unique fingerprint due to variances in radio frequency and manufacturing. By using an algorithm that repeatedly sent reader-to-tag signals, the researchers found that radio frequencies in RFID tags ranged from 903 MHz to 927 MHz, and increased in increments of 2.4 megahertz. The measurements showed that each tag had a unique minimum power response at multiple radio frequencies, and that power responses were significantly different even in same-model tags. Thompson says the different minimal responses are just one of several unique physical characteristics that enabled them to create an electronic fingerprint to identify tags with a high probability of detecting counterfeit tags.

Andy Johnson, a professor in the University of Illinois at Chicago’s Electronic Visualization Laboratory, is developing ultra-high-speed connections paired with high-definition video collaboration. Johnson says the technology is similar to commercial video phone services, but is more reliable, larger, and has a much clearer display. A stable, high-resolution video connection could change how people consult with doctors, auto mechanics diagnose cars, or businesspeople hold meetings, he says. The technology pairs life-sized display screens with near-instant Internet connections. “That gives us a much higher resolution interaction, and could make it much easier for remote groups to work together,” Johnson says. However, the system will require the United States to upgrade its Internet infrastructure with fiber-optic cables to increase access speeds.

Florida State University (FSU) researchers have discovered four crystals that possess properties which could lead to the development of a new generation of computer chips and other information storage devices. “We identified these four crystals as ‘multiferroic,’ meaning that they are simultaneously ferromagnetic and ferroelectric in nature when cooled to a specific temperature,” says FSU professor Naresh Dalal. Multiferroic crystals could be used to create high-powered computer memories that could hold far more information than is currently possible, says FSU professor Sir Harold Kroto. “Theoretically, it might be possible to design devices that are much smaller and faster than the ones we use today to store and transmit data,” Kroto says. The researchers say that electronic devices using multiferroic crystals would have far less environmental impact than devices used today. “The four new multiferroic crystals that we have identified all substitute other, less toxic metals for lead, which is a potent neurotoxin,” Dalal says.

The United States is engaged in an international race to develop both cyberweapons and cyberdefenses. Thousands of daily attacks on federal and private computer systems in the United States, some malicious and some testing for weak points in the U.S.’s firewalls, have prompted the Obama administration to review the nation’s strategy. Efforts include developing a highly classified replica of the Internet of the future to simulate what would be needed for the country’s enemies to shut down power stations, telecommunications, and aviation systems. Obama is expected to propose a significantly larger cyberdefensive effort, including the expansion of a $17 billion, five-year program approved by Congress last year, as well as an end to the bureaucratic battle over who is responsible for defending the country’s cyberinfrastructure. However, Obama is not expected to discuss the U.S.’s cyberoffensive capabilities, which has been a major investment area for the nation’s intelligence agencies, as many of these cyberweapons remain classified. The White House declined to comment on whether Obama supports or opposes the use of U.S. cyberweapons. Some exotic cyberweapons under consideration would enable a military programmer to enter a computer server in Russia or China and destroy a botnet, or activate malicious code that is secretly embedded on computer chips when manufactured, enabling the U.S. to take control of an enemy’s computer system.

The fusion of high-performance computing (HPC) and high-performance data (HPD) could potentially result in the generation of robust systems that are at least one order of magnitude faster than anything the HPC community currently uses for certain applications, says San Diego Supercomputer Center (SDSC) interim director Michael Norman. Last November, SDSC announced plans to construct Gordon, a data-intensive supercomputer that is expected to read latency-bound files at 10 times the speed and efficiency of current HPC systems with the help of flash memory solid state drives. Ultimately, Gordon will possess 245 teraflops of total compute power, 64 TB of digital random access memory, and 256 TB of flash memory. Gordon also will assist in the integration of HPC and HPD because it is designed for data-intensive predictive science as well as data-mining applications.

Japanese scientists have developed a statistical program that could enable portable baby-monitoring devices to determine whether infant cries mean a baby is sleepy, hungry, needs a change, or is in pain. Tomomasa Nagashima and colleagues at the Muroran Institute of Technology used a sound pattern recognition strategy to analyze infants’ crying patterns. The team analyzed the frequency of cries and the power function of the audio spectrum to classify different types of crying. Nagashima and colleagues were able to correlate the different recorded audio spectra with the emotional state of a baby as confirmed by the parents. Recordings of a crying baby with a painful genetic disorder helped the researchers differentiate the cries of babies who are in pain. They were able to achieve a 100 percent success rate in classifying pained cries and normal cries via their technique.
