Developmental Cell
Technique finds gene regulatory sites without knowledge of regulators
A new statistical technique developed by researchers at the University of Illinois allows scientists to scan a genome for specific gene-regulatory regions without requiring prior knowledge of the relevant transcription factors. The technique has been experimentally validated in both the mouse genome and the fruit fly genome.

150th Anniversary Celebration of the Riemann Hypothesis
Putting math problems in proper order
The American Institute of Mathematics announces a new online tool for creating and maintaining lists of unsolved mathematics problems. This tool has the potential to change mathematics research by bringing a wider range of people and expertise in contact with research questions. The tool is being released on the same day as a worldwide celebration of the 150th anniversary of the most important problem in mathematics: the Riemann Hypothesis.

Structured reporting software creates less complete and accurate radiology reports than free text
As many software companies work to create programs that will give uniform structure to the way radiological test results are reported, a new study by researchers at Wake Forest University School of Medicine shows that such a system does not improve, but rather decreases the completeness and accuracy of the reports.

NIST demonstrates 'universal' programmable quantum processor
Physicists at the National Institute of Standards and Technology have demonstrated the first "universal" programmable quantum information processor able to run any program allowed by quantum mechanics�the rules governing the submicroscopic world -- using two quantum bits (qubits) of information. The processor could be a module in a future quantum computer, which theoretically could solve some important problems that are intractable today.

Physical Review Letters
In touch with molecules
The performance of modern electronics increases steadily on a fast pace thanks to the ongoing miniaturization of the utilized components. However, severe problems arise due to quantum-mechanical phenomena when conventional structures are simply made smaller and reach the nanometer scale. Therefore current research focuses on the so-called bottom-up approach: the engineering of functional structures with the smallest possible building blocks -- single atoms and molecules.

Working together to design robust silicon chips
The EUREKA MEDEA+ microelectronics Cluster ROBIN project has resulted in much improved design methods for high performance silicon chips. Leading European semiconductor chipmakers, electronic circuit developers and design automation equipment manufacturers worked closely together to tackle a series of problems much earlier in the design phase and so enhance integrated circuit design approaches. New faster design flows for more robust chips have provided a boost for the whole European semiconductor fabrication industry.

Improving security with face recognition technology
A number of US states now use facial recognition technology when issuing drivers licenses. Similar methods are also used to grant access to buildings and to verify the identities of international travelers. Historically, obtaining accurate results with this type of technology has been a time intensive activity. Now, a researcher from the University of Miami College of Engineering and his collaborators have developed ways to make the technology more efficient while improving accuracy.

Rutgers computer scientists work to strengthen online security
If you forget your password when logging into an e-mail or online shopping Web site, the site will likely ask you a security question: What is your mother's maiden name? Where were you born? The trouble is that such questions are not very secure. But Rutgers computer scientists are testing a new tactic that could be both easier and more secure.
