In the campy 1966 science fiction movie “Fantastic Voyage,” scientists miniaturize a submarine with themselves inside and travel through the body of a colleague to break up a potentially fatal blood clot. Right. Micro-humans aside, imagine the inflammation that metal sub would cause.

Ideally, injectable or implantable medical devices should not only be small and electrically functional, they should be soft, like the body tissues with which they interact. Scientists from two UChicago labs set out to see if they could design a material with all three of those properties.

The material they came up with, published online June 27, 2016, in Nature Materials, forms the basis of an ingenious light-activated injectable device that could eventually be used to stimulate nerve cells and manipulate the behavior of muscles and organs.

I like this article because I have for years looked at options to address the counterfeiting issues which is a extremely costly criminal industry around diamonds and artwork. As we have seen with synthetic diamonds in their use in QC and medical technology there is a lot that technology can do in addressing the counterfeiting issues as well as registration & certification space. Also, could registered & embedded serialized stones be another form of id for the consumer who wears their accessory with the stone? I believe it can be.

Columbia Engineering Professor Changxi Zheng’s new approach could lead to better tagging and coding, leveraging 3D printing of complex geometries.

New York — July 18, 2016 — Columbia Engineering researchers, working with colleagues at Disney Research and MIT, have developed a new method to control sound waves, using a computational approach to inversely design acoustic filters that can fit within an arbitrary 3D shape while achieving target sound filtering properties. Led by Computer Science Professor Changxi Zheng, the team designed acoustic voxels, small, hollow, cube-shaped chambers through which sound enters and exits, as a modular system. Like Legos, the voxels can be connected to form an infinitely adjustable, complex structure. Because of their internal chambers, they can modify the acoustic filtering property of the structure—changing their number and size or how they connect alters the acoustic result.

“In the past, people have explored computational design of specific products, like a certain type of muffler or a particular shape of trumpet,” says Zheng, whose team is presenting their paper, “Acoustic Voxels: Computational Optimization of Modular Acoustic Filters,” at SIGGRAPH 2016 on July 27. “The general approach to manipulating sound waves has been to computationally design chamber shapes. Our algorithm enables new designs of noise mufflers, hearing aids, wind instruments, and more — we can now make them in any shape we want, even a 3D-printed toy hippopotamus that sounds like a trumpet.” VIDEO: http://www.cs.columbia.edu/cg/lego/

This will definitely make designer wear fashion very collectable and easier for investigators and consumer to detect fakes due to biometric readers. Unfortunately, Coco Chanel and Gianni Versace are not around to participate.

Designer Tina Gorjanc is using Alexander McQueen’s DNA to grow “skin” complete with freckles and tattoos that will be tanned to create jackets and bags.

Can serve many uses such as geneology, etc. However, the bigger advancement will be with criminal/ legal investigations.

Rice University researchers have developed gas biosensors to “see” into soil and allow them to follow the behavior of the microbial communities within.

In a study in the American Chemical Society’s journal Environmental Science and Technology, the Rice team described using genetically engineered bacteria that release methyl halide gases to monitor microbial gene expression in soil samples in the lab.

3D print materials and products with superconducting properties is truly a breakthrough towards the mass production of various complex materials. I see this as a large step forward for 3D and placing things on an evolution track to even mass produce synthetic diamonds.

3D printing is revolutionizing many areas of manufacturing and science. In particular, 3D printing of metals has found novel applications in fields as diverse as customized medical implants, jet engine bearings and rapid prototyping for the automotive industry.

While many techniques can be used for 3D printing with metals, most rely on computer-controlled melting or sintering of a metal alloy powder by a laser or electron beam. The mechanical properties of parts produced by this method have been well studied, but not enough attention has focused on their electrical properties.

Purifying H₂O more cheaply.

WASHINGTON—(BUSINESS WIRE)—Organic compounds in wastewater, such as dyes and pigments in industry effluents, are toxic or have lethal effect on aquatic living and humans. Increasing evidence has shown that the organic contaminants discharged from electroplating, textile production, cosmetics, pharmaceuticals are the main reasons for the higher morbidity rates of kidney, liver, and bladder cancers, etc. Organic contaminants, especially methyl blue and methyl orange, are stable to light, heat or oxidizing agents and very difficult to remove by conventional chemical or biological wastewater treatment techniques. Recently scientists have developed some new strategies with good dye-removal performance; however, a subsequent adsorbent purification procedure is unavoidable after water treatment, which are often complicated and not suitable for practical water treatment.

Now, using laser-induced fabrication technique, a team of Chinese researchers from Shandong University, China, have developed a novel dye adsorbent. Hybrid nano-particles of silver and silver sulfide (Ag₂S@Ag hybrid nano-particles) have demonstrated the nanomaterial’s superior adsorption performance for removing methyl blue and methyl orange from wastewater. More importantly, the new adsorbents can be removed directly from solutions by filters without adsorbent purification procedures, as the silver-based hybrid nano-particles will be agglomerated and deposited on the bottom after adsorbing dyes, providing a green, simple, rapid and low-cost solution for water purification. This week in the journal Optical Materials Express, from The Optical Society (OSA), the researchers describe the work.

Way cool! Your stitches monitors and reports your progress to your doctor/s.

BTW — In 1999, I told a guy from Diamond Intl. that the thread in our clothing would be able to do this in the next 15 to 20 years. He laughed at me; never say never.

For the first time, researchers led by Tufts University engineers have integrated nano-scale sensors, electronics and microfluidics into threads — ranging from simple cotton to sophisticated synthetics — that can be sutured through multiple layers of tissue to gather diagnostic data wirelessly in real time, according to a paper published online July 18 in Microsystems & Nanoengineering. The research suggests that the thread-based diagnostic platform could be an effective substrate for a new generation of implantable diagnostic devices and smart wearable systems.
