Biowire.


Researchers led by microbiologist Derek Lovely say the wires, which rival the thinnest wires known to man, are produced from renewable, inexpensive feedstocks and avoid the harsh chemical processes typically used to produce nanoelectronic materials.

Lovley says, “New sources of electronic materials are needed to meet the increasing demand for making smaller, more powerful electronic devices in a sustainable way.” The ability to mass-produce such thin conductive wires with this sustainable technology has many potential applications in electronic devices, functioning not only as wires, but also transistors and capacitors. Proposed applications include biocompatible sensors, computing devices, and as components of solar panels.

This advance began a decade ago, when Lovley and colleagues discovered that Geobacter, a common soil microorganism, could produce “microbial nanowires,” electrically conductive protein filaments that help the microbe grow on the iron minerals abundant in soil. These microbial nanowires were conductive enough to meet the bacterium’s needs, but their conductivity was well below the conductivities of organic wires that chemists could synthesize.

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/

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 samples in the lab.

The bacteria are programmed using synthetic biology to release gas to report when they exchange DNA through , the process by which organisms share genetic traits without a parent-to-child relationship. The biosensors allow researchers to monitor such processes in real time without having to actually see into or disturb a lab soil sample.

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.

Now in a paper appearing this week on the cover of the journal Applied Physics Letters, a team of University of Melbourne and University of Western Australia researchers report creating a resonant microwave cavity that they 3D printed viaan aluminum-silicon alloy (Al-12Si). It exhibits superconductivity when cooled below the critical temperature of aluminum (1.2 Kelvin).
