Cyberlearning Platforms Improve Design Collaboration

Two new "cyberlearning" platforms allow non-artists to create illustrations rivaling the work of expert designers. The platforms sidestep a key creative barrier by eliminating the need for drawing skills in developing new designs. "Non-experts are becoming more empowered and interested in means of creative self-expression," said Karthik Ramani, Purdue University's Donald W. Feddersen Professor of Mechanical Engineering. "More importantly, I think this is the beginning of a new field of computer-supported creativity where you are extending the human mind." The new platforms — called skWiki (pronounced squeaky) and Juxtapoze — may usher in a new era of digital-scribbling and creative collaboration. The platforms operate on servers and do not require users to install any software. The skWiki platform allows collaboration with multimedia, including text, sketches, photos and "vector images" important for computer-aided design and other applications.

Earth-Sized Exoplanet Discovered via Observatory Data

The National Science Foundation-funded Gemini observatory helped confirm the first potentially habitable Earth-sized exoplanet. Researchers say this discovery is unique because the planet, called Kepler-186f, resides in a temperate region around its host star where water could exist and could possibly sustain life. Earth-sized planets are very difficult to detect because of contrast with their host stars.

Wind Tunnel Tests Support Improved Design of B61-12 Bomb

Sandia National Laboratories has finished testing a full-scale mock unit representing the aerodynamic characteristics of the B61-12 gravity bomb in a wind tunnel. The tests on the mock-up were done to establish the configuration that will deliver the necessary spin motion of the bomb during freefall and are an important milestone in the Life Extension Program to deliver a new version of the aging system.

Testing Composite Structures for Stronger Bridges

The J. Lohr Structures Laboratory at South Dakota State University helps companies develop new materials and products — self-consolidating concrete columns and pre-stress concrete bridge girders — that bridge a physical gap. Over the past decade, researchers have conducted structural testing on large- and full-scale test specimens for private companies and government entities.

With New Sensors, NASA's Morpheus Preps to Land on its Own

A test flight will challenge a set of sensors to map out a 65-yard square of boulder-sized hazards and pick out a safe place to land. Mounted to an uncrewed prototype lander called Morpheus that flies autonomously several hundred feet above the ground, the sensor system will have 10 seconds to do its work. The sensor system is a 400-pound set of computers and three instruments called ALHAT (Autonomous Landing and Hazard Avoidance Technology).

Scientist Creates Three-Atom-Wide Nanowire

Junhao Lin, a Vanderbilt University Ph.D. student and visiting scientist at Oak Ridge National Laboratory (ORNL), has found a way to use a finely focused beam of electrons to create some of the smallest wires ever made. The flexible metallic wires are only three atoms wide: One thousandth the width of the microscopic wires used to connect the transistors in today’s integrated circuits.The technique represents an exciting new way to manipulate matter at the nanoscale and should give a boost to efforts to create electronic circuits out of atomic monolayers, the thinnest possible form factor for solid objects.“This will likely stimulate a huge research interest in monolayer circuit design,” Lin said. “Because this technique uses electron irradiation, it can in principle be applicable to any kind of electron-based instrument, such as electron-beam lithography.”One of the intriguing properties of monolayer circuitry is its toughness and flexibility.“If you let your imagination go, you can envision tablets and television displays that are as thin as a sheet of paper that you can roll up and stuff in your pocket or purse,” said University Distinguished Professor of Physics and Engineering at Vanderbilt University, Sokrates Pantelides.SourceAlso: Learn about a Zinc Oxide Nanowire Interphase.

Big Ideas for Small Spaces

Over 24 hours from April 4 to 5, six top French design studios conceived and presented new product concepts for urban environments during the Small Spaces Design Hackathon, presented by Cut&Paste in partnership with Hewlett-Packard. In dense city neighborhoods, homes are small and office space is at a premium, so urban dwellers must be more creative in how they use their space. The design concepts were presented at Cyclone Le Studio as part of ZED, HP’s creative popup space.
