Solar thermophotovoltaics A team of MIT researchers demonstrated a device based on a method that enables solar cells to break through a theoretically predicted ceiling on how much sunlight they can convert into electricity. Since 1961 it has been known that there is an absolute theoretical limit, called the Shockley-Queisser Limit, to how efficient traditional solar cells can be in their ... » read more

Reconfigured Tesla coil electrifies materials In a development that could set a clear path toward scalable assembly of nanotubes from the bottom up, Rice University researchers have discovered that the strong force field emitted by a Tesla coil causes carbon nanotubes to self-assemble into long wires, a phenomenon they call Teslaphoresis. Rice chemist Paul Cherukuri led the team that develo... » read more

Debugging web apps MIT researchers reported that they’ve developed a system that can quickly comb through tens of thousands of lines of application code to find security flaws by exploiting some peculiarities of the Ruby on Rails web programming framework. The team said that in tests on 50 popular web applications written using Ruby on Rails, the system found 23 previously undiagnosed sec... » read more

Highly aligned, wafer-scale films Rice University researchers, with support from Los Alamos National Laboratory, have created inch-wide, flexible, wafer-scale films of highly aligned and closely packed carbon nanotubes with the help of a simple filtration process. The chirality-enriched single-walled carbon nanotubes assemble themselves by the millions into long rows that are aligned better... » read more

Cryptographic system for controlling app access to data Researchers at MIT and Harvard University are hoping to change the fact that users of smartphones have no idea which data items their apps are collecting, where they’re stored, and if they’re stored securely with an application they’ve developed called Sieve. With Sieve, a Web user would store all personal data, in encrypted form... » read more

How nanocrystal structures self assemble Researchers at MIT and the Cornell High Energy Synchrotron Source (CHESS) have discovered some of the secrets to a long-hidden magic trick behind the self-assembly of nanocrystal structures, the understanding of which could be used to create more vivid display screens and optical sensory devices. The transformation of simple colloidal particles — b... » read more

Drilling into metabolic details with big data In a development that may help researchers find new therapeutic targets for cancer and other diseases, Rice University researchers have created a fast computational method to model tissue-specific metabolic pathways. The team explained that metabolic pathways are immense networks of biochemical reactions that keep organisms functioning and are a... » read more

Magnetic computing Engineers at the University of California, Berkeley, demonstrated that magnetic chips can operate with the lowest fundamental level of energy dissipation possible under the laws of thermodynamics. "We wanted to know how small we could shrink the amount of energy needed for computing," said Jeffrey Bokor, a UC Berkeley professor of electrical engineering and computer sci... » read more
