How can defense or intelligence agencies safeguard the security of top-secret data protected by a computation device the size of a single molecule?
With cryptography approaching that sobering new era, scientists in Israel are reporting development of what they term the first molecular system capable of processing password entries. Abraham Shanzer and colleagues describe their "molecular keypad lock" in the Jan. 17 issue of the weekly Journal of the American Chemical Society.

The theorists who first created the mathematics that describe the behavior of the recently announced "invisibility cloak" have revealed a new analysis that may extend the current cloak's powers, enabling it to hide even actively radiating objects like a flashlight or cell phone.
Allan Greenleaf, professor of mathematics at the University of Rochester, working with colleagues around the globe, has announced a mathematical theory that predicts some strange goings on inside the cloak—and that what happens inside is crucial to the cloak's effectiveness.

New research may provide insight as to why, despite progress over the last few decades, women remain underrepresented in math-heavy majors and professions.
In an article published in the January issue of Psychological Science, psychologists Amy Kiefer of the University of California, San Francisco and Denise Sekaquaptewa of the University of Michigan point to an interaction between women's own underlying "implicit" stereotypes and their gender identification as a source for their underperformance and lowered perseverance in mathematical fields.
