Printing Artificial Bone
June 17, 2013 | by Denise Brehm, Massachusetts Institute of Technology | Comments
Researchers working to design new materials that are durable, lightweight and environmentally sustainable are increasingly looking to natural composites, such as bone, for inspiration: Bone is strong and tough because its two constituent materials, soft collagen protein and stiff hydroxyapatite mineral, are arranged in complex hierarchical patterns that change at every scale of the composite, from the micro up to the macro.

That person could be The One. It turns out that radiologists can do this with mammograms, the x-ray images used for breast cancer screening.
UC Research Examines How Technology Can Break Down Barriers for Deaf and Hard-of-Hearing Students
June 17, 2013 12:05 pm | by University of Cincinnati | CommentsA small, pilot study is examining how mobile technology might support deaf and hard-of-hearing college students when an interpreter can’t physically be present at the time the services are requested. The first phase of the UC research project involved a college student taking a course in a large, auditorium-style classroom.
Is There an Invisible Tug-Of-War Behind Bad Hearts and Power Outages?
June 17, 2013 11:53 am | by Princeton University | CommentsSystems such as a beating heart or a power grid that depend on the synchronized movement of their parts could fall prey to an invisible and chaotic tug-of-war known as a "chimera." Sharing its name with the fire-breathing, zoologically patchy creature of Greek mythology, a chimera state arises among identical, rhythmically moving components...

New Nanoneedle Helping Scientists Uncover Secrets Under the Skin
June 14, 2013 9:22 am | by University of Bath | CommentsResearchers in the University’s Physics and Pharmacy & Pharmacology Departments are using a pioneering technique to study the properties and characteristics of our skin, in tests that could pave the way for new treatments for dermatitis, and for an improved understanding of the skin ageing process.
New Array Measures Vibrations Across Skin May Help Engineers Design Tactile Displays
June 14, 2013 9:16 am | by Massachusetts Institute of Technology | CommentsIn the near future, a buzz in your belt or a pulse from your jacket may give you instructions on how to navigate your surroundings. Think of it as tactile Morse code: vibrations from a wearable, GPS-linked device that tell you to turn right or left, or stop, depending on the pattern of pulses you feel. Such a device could free drivers from having to look at maps, and could also serve as a tactile guide for the visually and hearing impaired.
Autonomous, Energy-Scavenging, Micro Devices Serve as Biomedical Monitors
June 14, 2013 9:10 am | by SPIE | CommentsOut in the wilds or anywhere off the grid, sophisticated instruments small enough to fit in a shirt pocket will one day scavenge power from sunlight, body heat, or other sources to monitor water quality or bridge safety or function as wearable biomedical monitors, enabling analysis in the field rather than bringing samples and data back to the lab.
