Encryption might not be enough for all that data stored in the cloud. An analysis of usage patterns — which files are accessed and when — can give away secrets as well. Computer scientists at Brown have developed an algorithm to sweep away those digital footprints. It’s a complicated series of dance-like moves they call the Melbourne Shuffle. To keep data safe in the cloud, a group of computer scientists suggests doing the Melbourne Shuffle.

Increasing energy efficiency in buildings requires substantial coordination between design engineers and architects. Researchers at Princeton University applied a common structural form-finding technique to predict the equilibrium shapes and elastic energies of dielectric elastomer minimum energy structures (DEMES).

The National Nanotechnology Initiative defines nanotechnology as the understanding and control of matter at the nanoscale, at dimensions of approximately 1 and 100 nanometers, where unique phenomena enable novel applications. Nanotechnology is taking the world by storm, revolutionizing the materials and devices used in many applications and products. That’s why a finding announced by Xiang-Feng Zhou and Artem R. Oganov, Group of Theoretical Crystallography in the Department of Geosciences, are so significant.

In a recent article published in Materials Letters, Sarute Ummartyotin and Mohini Sain of the Center for Biocomposite and Biomaterials Processing described their success in preparing a cellulose and water-based resin composite. The polymer industry has been intensely searching for a way to produce typically petroleum based polymers and composites with a renewable resource. Cellulose, an abundant and natural bio-based polymer, has attracted a lot of attention in this arena.

Computer chips keep getting faster because transistors keep getting smaller. But the chips themselves are as big as ever, so data moving around the chip, and between chips and main memory, has to travel just as far. As transistors get faster, the cost of moving data becomes, proportionally, a more severe limitation.

Researchers at MIT and the Université Pierre et Marie Curie in Paris provide the first detailed model for the 3-D shape of a strand of curly hair. This work could have applications in the computer animation film industry, but it also could be used by engineers to predict the curve that long steel pipes, tubing, and cable develop after being coiled around a spool for transport.
