Stretching-insensitive stretchable and biocompatible triboelectric nanogenerators
Professor Juhyuk Lee of the Department of Energy Engineering has developed an elastic triboelectric generator that can be used in the daily lives of frequent movers. The cause of the output reduction of the elastic triboelectric sensor was identified.....»»
Wound treatment hydrogel infused with amino acid kills bacteria naturally and promotes cell growth
Hydrogels are popular for use in skin ailments and tissue engineering. These polymer-based biocompatible materials are useful for their abilities to retain water, deliver drugs into wounds, and biodegrade. However, they are complicated to manufacture.....»»
How to safely watch a solar eclipse with children
The next solar eclipse will be visible across North America on April 8. Solar eclipses occur when the moon passes between the sun and the Earth, blocking sunlight and casting a shadow on our planet. There will be a 115-mile-wide path stretching from.....»»
Tips to safely watch the total solar eclipse
On April 8, North America will experience a total solar eclipse, stretching across parts of Mexico, the U.S. and Canada, with approximately 31.6 million people living in the path of totality. According to NASA, every contiguous state in the U.S., alo.....»»

New, highly stretchable sensors can monitor and transmit plant growth information without human intervention, report University of Illinois Urbana-Champaign researchers in the journal Device......»»
Scientists develop biocompatible fluorescent spray that detects fingerprints in ten seconds
Scientists have developed a water-soluble, non-toxic fluorescent spray that makes fingerprints visible in just a few seconds, making forensic investigations safer, easier and quicker......»»
How to dim the consequences of global light pollution
Our ancestors could look up and see the Milky Way—our galaxy—as a large band of white light stretching across the sky. Because of light pollution, that's no longer the case. One study estimated that 60% of Europeans and 80% of Americans have neve.....»»
For couples, negative speaks louder than positive
After a long day, a couple cuddles together while watching a favorite show, taking comfort in each other's touch, scent and voices—until one partner makes an insensitive comment. Will the comment be quickly forgotten, or might it signal trouble for.....»»
The Last-Ditch Effort to Stop the Mountain Valley Pipeline
The gas pipeline stretching across Virginia and West Virginia is over budget and behind schedule, with a lot of hard work left to do. Opponents hope that makes fossil fuel companies think twice about building the next one......»»
Mars Express finds evidence of large water deposit at the Medusae Fossae Formation
Windswept piles of dust, or layers of ice? ESA's Mars Express has revisited one of Mars's most mysterious features to clarify its composition. Its findings suggest layers of water ice stretching several kilometers below ground—the most water ever f.....»»
Largest deep-sea coral reef to date is mapped by scientists off the US Atlantic coast
Scientists have mapped the largest coral reef deep in the ocean, stretching hundreds of miles off the U.S. Atlantic coast......»»
Transferring laser-induced graphene at extremely low temperatures for ultrathin bioelectronics
A recent study published in Nature Electronics discusses stretchable graphene–hydrogel interfaces for wearable and implantable bioelectronics......»»
The early universe was surprisingly filled with spiral galaxies, research suggests
If we could travel far beyond our galaxy, and look back upon the Milky Way, it would be a glorious sight. Luminous spirals stretching from a central core, with dust and nebulae scattered along the spiral edges. When you think about a galaxy, you prob.....»»
Developing a futuristic elastomer with ultrahigh strain-induced crystallization
Strain-induced crystallization can strengthen, toughen, and facilitate an elastocaloric effect in elastomers. The resulting crystallinity can be induced by mechanical stretching in common elastomers that are typically below 20%, with a stretchability.....»»
Elastane recycling: Stretching the lifespan of textiles
Clothing is far too valuable to simply dispose of and burn. Starting in 2025, used textiles are to be collected and recycled throughout the EU. Improved recycling processes are urgently needed to deal with the huge amount of textiles that will then b.....»»

There is good news for researchers working with high-resolution fluorescence microscopy: Biocompatible molecular rulers are available for the first time to calibrate the latest super-resolution microscopy methods......»»
Destiny 2: The Final Shape gets a new release date after team layoffs
Destiny 2: The Final Shape will now land in June, stretching Season of the Wish a few extra months following layoffs at Bungie......»»
Hydrogel-assisted microfluidic spinning of stretchable fibers via fluidic and interfacial self-adaptation
Stretchable polymeric fibers have significant impact, although their production requires rigorous environmental methods and resource consumption. The process is challenging for elastic polymers with reduced spinnability and high performance, such as.....»»
1-year Sam"s Club membership for $20 & take the pain out of holiday shopping
The price of groceries is stretching budgets to the limit, but buying goods in bulk almost always helps save a few precious dollars, especially when feeding a family. Luckily, this $20 Sam's Club membership deal can save you big bucks this holiday se.....»»
Measuring mechanical stresses and strains in graphene-based supercapacitor electrodes
Texas A&M University researchers have discovered that when charging a supercapacitor, it stores energy and responds by stretching and expanding. This finding can be used to design new materials for flexible electronics or other devices that must be b.....»»
