Morphing origami takes a new shape, expanding use possibilities

A new type of origami can morph from one pattern into a different one, or even a hybrid of two patterns, instantly altering many of its structural characteristics. Credit: Allison Carter Origami-based structures have been used to create deployable solar arrays for space, adaptable acoustic systems for symphony halls and even crash protection systems for…

Engineers tap DNA to create ‘lifelike’ machines

Cornell professor of biological and environmental engineering Dan Luo and research associate Shogo Hamada have created a DNA material capable of metabolism, in addition to self-assembly and organization. Credit: John Munson/Cornell University Tapping into the unique nature of DNA, Cornell engineers have created simple machines constructed of biomaterials with properties of living things. Using what…

In a major medical breakthrough, Tel Aviv University researchers have "printed" the world's first 3D vascularised engineered heart using a patient's own cells and biological materials. Their findings were published on April 15 in a…

Cold plasma can kill 99.9% of airborne viruses

Civil and Environmental Engineering Professor Herek Clack (left) and members of his team set up a lab-scale non-thermal plasma device that has previously been proven to achieve greater than 99% inactivation of an airborne viral surrogate, MS2 phage, a virus that infects E.coli bacteria at the Barton Farms family pig farm in Homer, MI.

Biomedical engineers grow cardiac patches to help people recover from heart...

Zhao and her team have shown the potential of biomimicry to grow microvessels in tissues suitable for a cardiac patch. The next steps will be animal trials and refining medical technology for implants and devices. With the help of tiny, dense, neatly aligned blood vessels, engineered tissues could help hearts, skin, bones and muscles regenerate…

4D-printed materials can be stiff as wood or soft as sponge

4D-printed metamaterials can be temporarily transformed into any deformed shape and then returned to their original shape on demand when heated. The scale bar is 2 millimeters.

True-meaning wearable displays: Self-powered, washable and wearable

Schematic and photo of a washable wearing display module. Credit: KAIST When we think about clothes, they are usually formed with textiles and have to be both wearable and washable for daily use; however, smart clothing has had a problem with its power sources and moisture permeability, which causes the devices to malfunction. This problem…

Engineers demonstrate metamaterials that can solve equations

University of Pennsylvania Engineers have designed a metamaterial device that can solve integral equations. The device works by encoding parameters into the properties of an incoming electromagnetic wave; once inside, the device's unique structure manipulates the wave in such a way that it exits encoded with the solution to a pre-set integral equation for that…

From foam to bone: Plant cellulose can pave the way for...

Researchers treated nanocrystals derived from plant cellulose so that they can link up and form a strong but lightweight sponge (an aerogel) that can compress or expand as needed to completely fill out a bone cavity.

Levitating objects with light

Conceptual illustration of a nano-patterned object reorienting itself to remain in a beam of light. Credit: Courtesy of the Atwater laboratory Researchers at Caltech have designed a way to levitate and propel objects using only light, by creating specific nanoscale patterning on the objects' surfaces. Though still theoretical, the work is a step toward developing…

Movie technology inspires wearable liquid unit that aims to harvest energy

A Purdue University team created wearable technology to convert mechanical energy into electrical energy. Credit: Wenzhuo Wu/Purdue University A fascination with movie technology that showed robots perform self-repair through a liquid formula inspired a Purdue University professor to make his own discoveries -- which are now helping to lead the way for advancements in self-powering…

A robotic leg, born without prior knowledge, learns to walk

A team of researchers at the USC Viterbi School of Engineering believe they have become the first to create an AI-controlled robotic limb driven by animal-like tendons that can even be tripped up and then recover within the time of the next footfall, a task for which the robot was never explicitly programmed to do.…

Controlling thermal conductivity of polymers with light

Under ambient conditions or visible light (left side), the polymer is crystalline and has a high thermal conductivity. Once exposed to ultraviolet (UV) light (right side) it transforms to a low thermal conductivity liquid. Imaging performed using polarized optical microscopy; crystals appear bright, and liquid dark. Inset images show schematic illustration of crystalline and liquid…
