Untraceable text-messaging Anonymity networks, like Tor, which sit on top of the public Internet, were meant to conceal Web-browsing habits but recent research by MIT has shown that adversaries can infer a great deal about the sources of supposedly anonymous communications by monitoring data traffic though a few well-chosen nodes in an anonymity network. To fight this growing concern, a tea... » read more

Reducing transistor switching power One of the great challenges in electronics has been to reduce power consumption during transistor switching operation. However, engineers at University of California, Santa Barbara, and Rice University demonstrated a new transistor that switches at only 0.1 volts and reduces power dissipation by over 90% compared to state-of-the-art MOSFETs. "The steepn... » read more

Speedy nano-scale subs For years, researchers have been developing nano-scale submarines. In theory, nano-subs could be used in various applications. For example, they could navigate inside the human body and transport medicine to various organs. The problem? Most nano-subs use or generate toxic chemicals, according to researchers from Rice University. Seeking to solve the problem, Rice ... » read more

Wrapping silver nanowires While they hold promise for applications including flexible displays and solar cells, silver nanowires are also susceptible to damage from highly energetic UV radiation and harsh environmental conditions has limited their commercialization, according to Purdue University researchers. However, new research suggests wrapping the nanowires with an ultrathin layer of c... » read more

Automating big-data analysis Until now, big-data analysis consisted of searching for buried patterns that had some kind of predictive power but picking which “features” of the data to analyze usually required some human intuition. Now, however, MIT researchers are aiming to take the human element out of big-data analysis with a new system that they say not only searches for patterns but... » read more

Solar water-splitting By splitting water molecules, Rice University researchers have demonstrated what they say is an efficient way to capture energy from the sun and convert it into clean, renewable energy. The technology relies on a configuration of light-activated gold nanoparticles that harvest sunlight and transfer solar energy to highly excited electrons, which scientists sometimes re... » read more

Reducing crosstalk with tantalum oxide memories Scientists at Rice University created a solid-state memory technology that allows for high-density storage with a minimum incidence of crosstalk errors. The memories are based on tantalum oxide. Applying voltage to a 250-nanometer-thick sandwich of graphene, tantalum, nanoporous tantalum oxide and platinum creates addressable bits where the ... » read more
