Rice Univ. scientists have created an Earth-friendly way to separate carbon dioxide from natural gas at wellheads. A porous material invented by the Rice laboratory of chemist James Tour sequesters carbon dioxide, a greenhouse gas, at ambient temperature with pressure provided by the wellhead and lets it go once the pressure is released. The material shows promise to replace more costly and energy-intensive processes.
A Swiss-made solar-powered aircraft has made a successful inaugural flight as its makers prepare for what they hope will be the first round-the-world solar flight. The aircraft spent 2 hours and 17 minutes in the air above western Switzerland early Monday. The Solar Impulse 2 is a bigger and better version of a single-seat prototype that first took flight five years ago and can theoretically stay airborne indefinitely.
The first preclinical study of a new Rice Univ.-developed anticancer technology found that a novel combination of existing clinical treatments can instantaneously detect and kill only cancer cells without harming surrounding normal organs. The research reports that Rice’s “quadrapeutics” technology was 17 times more efficient than conventional chemoradiation therapy against aggressive, drug-resistant head and neck tumors.
The SuperDraco thruster, an engine that will power SpaceX’s Dragon spacecraft to orbit, has completed a test regimen held over the last month at SpaceX’s Rocket Development Facility in Texas. This qualification test involves a variety of conditions conditions including multiple starts, extended firing durations and extreme off-nominal propellant flow and temperatures.
A team of researchers has successfully tracked single molecules inside living cells with carbon nanotubes. Through this new method, the researchers found that cells stir their interiors using the same motor proteins that serve in muscle contraction. The study, which sheds new light on biological transport mechanisms in cells, appears in Science.
At this year’s IEEE International Conference on Robotics and Automation, a research team introduced a new wrinkle on the idea of printable robots: bakable robots. In two new papers, the researchers demonstrate the promise of printable robotic components that, when heated, automatically fold into prescribed 3-D configurations.
Neuroscientists, engineers and physicians are teaming up for an ambitious five-year, $26 million project to develop new techniques for tackling mental illness. By using devices implanted in the brain, they aim to target and correct malfunctioning neural circuits in conditions such as clinical depression, addiction and anxiety disorders.
A Stanford Univ. electrical engineer has invented a way to wirelessly transfer power deep inside the body, and then use this power to run tiny electronic medical gadgets such as pacemakers, nerve stimulators or new sensors and devices yet to be developed. The discoveriesculminate years of efforts to eliminate the bulky batteries and clumsy recharging systems that prevent medical devices from being more widely used.
Scientists from the Biorobotics Laboratory (BIOROB) at EPFL in Switzerland have developed small robotic modules that can change their shape to create reconfigurable furniture. Like Lego bricks, these robotic pieces, or Roombots, can be stacked upon each other to create various structures. Each piece has three motors that allow the module to pivot with three degrees of freedom, and each also has a battery and wireless connection.
Researchers at Massachusetts Institute of Technology and the Univ. of Vienna have created an imaging system that reveals neural activity throughout the brains of living animals. This technique, the first that can generate 3-D movies of entire brains at the millisecond timescale, could help scientists discover how neuronal networks process sensory information and generate behavior.
Univ. of Utah researchers devised a way to watch newly forming AIDS virus particles emerging or “budding” from infected human cells without interfering with the process. The method shows a protein named ALIX gets involved during the final stages of virus replication, not earlier, as was believed previously.
Over the past three years, researchers in the Camera Culture group at the Massachusetts Institute of Technology Media Lab have steadily refined a design for a glasses-free, multi-perspective, 3-D video screen, which they hope could provide a cheaper, more practical alternative to holographic video in the short term.
Scientists at NASA Langley Research Center have developed a new material technology that alters a surface’s topography and chemistry to promote or mitigate adhesion. LaRC is holding a workshop and meeting on May 22 that explains how these newly available materials work to enhance or remove adhesion. Manufacturers and developers are welcome to attend.
Researchers from The Univ. of Texas at Dallas and the Univ. of Tokyo have created electronic devices that become soft when implanted inside the body and can deploy to grip 3-D objects, such as large tissues, nerves and blood vessels. These biologically adaptive, flexible transistors might one day help doctors learn more about what is happening inside the body, and stimulate the body for treatments.
It looks like a game board and many of its users will find it fun, but there’s serious intent behind a device by Rice Univ. students to test the abilities of cerebral palsy patients. At the heart of the DeXcellence platform is a small peg comfortable enough for a three-year-old to hold. But packed inside are enough electronics to tell a nearby computer, tablet or other Bluetooth-enabled device of how the cylinder is moving in space.
