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.

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.

ACM has named Cornell University professor Jon Kleinberg the winner of the 2008 ACM-Infosys Foundation Award in the Computing Sciences. ACM and the Infosys Foundation created the award in 2007 to recognize personal contributions by young scientists and system developers to a contemporary innovation that exemplifies the greatest recent achievements in the computing field. Kleinberg’s models show how information is organized on the Web, how it spreads through large social networks, and how the structure of these networks leads to the six degrees of separation phenomenon. “With his innovative models and algorithms, he has broadened the scope of computer science to extend its influence to the burgeoning world of the Web and the social connections it enables,” says ACM President Dame Wendy Hall. “We are fortunate to have the benefit of his profound insights into the link between computer network structure and information that has transformed the way information is retrieved and shared online.” ACM will present Kleinberg with the ACM-Infosys Foundation Award at the annual ACM Awards Banquet on June 27 in San Diego, Calif. Financial support for the $150,000 award is provided by an endowment from the Infosys Foundation.
