Keynote speaker: Dr. Ken Gabriel A veteran technologist with a distinguished track record of success across the public and private sectors, Dr. Ken Gabriel is credited with creating the MEMS industry through his role as co-founder of Akustica, a fabless semiconductor company that commercialized MEMS audio devices and sensors. In addition, Gabriel currently serves as Deputy Director of the Advanced Technology and Projects (ATAP) Group at Google and is the CEO of Draper Laboratory. He has also held the role of Deputy Director, and then Acting Director, of the Defense Advanced Research Projects Agency (DARPA) in the Department of Defense where he led an agency with an annual budget of $3 billion that is charged with managing the Department’s portfolio of its most cutting edge projects to both create and avoid technology surprise.

During his keynote Gabriel will leverage his vast experience to address how sensors are the unsung heroes of technology. To most consumers sensors are all part of a bigger package. To stand out you need to understand how consumers rely on the sensors you produce and then produce sensors that make devices stand out. Tools exist for you to understand how you can differentiate your products. Be more than a feature, be the discriminator for devices.

I reported on this finding which the National Labs in Oak Ridge TN published yesterday. This is MIT’s own report on the research and discovery of new material called bismuth selenide (Bi2Se3) with an ultrathin layer of a magnetic material, europium sulfide (EuS). I know that is a mouth full. However, the end result will be that it could lead to a new generation of electronics, spintronics, or quantum computing devices. Definitely a big move forward in bridging QC into all things that use daily.

A new and unexpected magnetic effect has taken researchers by surprise, and could open up a new pathway to advanced electronic devices and even robust quantum computer architecture.

The finding is based on a family of materials called topological insulators (TIs) that has drawn much interest in recent years. The novel electronic properties of TIs might ultimately lead to new generations of electronic, spintronic, or quantum computing devices. The materials behave like ordinary insulators throughout their interiors, blocking electrons from flowing, but their outermost surfaces are nearly perfect conductors, allowing electrons to move freely. The confinement of electrons to this vanishingly thin surface makes then behave in unique ways.

But harnessing the materials’ promise still faces numerous obstacles, one of which is to find a way of combining a TI with a material that has controllable magnetic properties. Now, researchers at MIT and elsewhere say they have found a way to overcome that hurdle.

Not saying that the whole Apple situation cause this; it just odd timing.

The Federal Communications Commission and Federal Trade Commission have asked mobile phone carriers and manufacturers to explain how they release security updates amid mounting concerns over security vulnerabilities, the U.S. agencies said on Monday.

The agencies have written to Apple, AT&T and Alphabet, among others, in order “to better understand, and ultimately to improve, the security of mobile devices,” the FCC said.

The FCC sent letters to six mobile phone carriers on security issues, while the FTC ordered eight mobile device manufacturers including BlackBerry, Microsoft, LG Electronics USA and Samsung Electronics America to disclose “the factors that they consider in deciding whether to patch a vulnerability on a particular mobile device.”

Samsung get into the cancer treatment space with their own Q-Dot technology? Another reason for the FDA to show up in tech’s backyard; lookout for all those future federal and state regs & compliance training that will be coming that eats up 20 hours each month of your scientists and engineering talent’s time.

For a lot of users, Samsung might be known best for their smartphones and other mobile devices, but the company is so much more than that. Many of you reading this might have one of Samsung’s Super HD TV sets, a curved Samsung TV or some other model of theirs. Next to smartphones one of their more popular consumer electronics is of course of TVs, and with the advent of new technology such as Quantum Dot, Samsung is getting even better at producing a great image. One area that you might expect to find this Quantum Dot technology being used is for medical uses, but that’s just what researchers have been exploring recently.

Explaining a Quantum Dot can become quite tricky, but to cut a long story short, they are semiconductors that are so small they register at the nanoscale side of things. In terms of Quantum Dots used in television displays, it’s their ability to precisely tune to a specific and exact part of the color spectrum that makes them so attractive, not to mention their much lower power draw. Now, Kim Sung-jee, a professor of the Chemistry department at Pohang University of Science and Technology (POSTECH), has said that “when combining protein which clings to cancer cells and quantum dots, it can be used to seek out cancer cells in the body”. It’s reasoned that the potential for these Quantum Dots to be so precise in terms of color reproduction can help physicians track down certain cancer cells.

Myung Seung-jae, chief director of Biomedical Research Center at Asan Institute for Life Sciences who joined Professor Kim in researching Quantum Dots to fight cancer, said that when a test was ran on animals with Cancer cells in their bodies drugs with Quantum Dots “attacked only cancer cells. When quantum dots meet cancer cells, they detect the change of potential of hydrogen (pH) and anti-cancer drugs”. So, while it seems a long way off, it looks like the same technology that makes for a more accurate and engaging picture for your TV could be used in order to fight cancer or at least better identify types of Cancer and how to combat them inside of the body.

General Atomics Electromagnetic Systems (GA-EMS) officials demonstrated its Blitzer electromagnetic railgun system at the U.S. Army’s Fires Center of Excellence annual Maneuver and Fires Integration Experiment (MFIX)last month at Ft. Sill in Lawton, Oklahoma.

There were eleven firings of the Blitzer railgun during the MFIX event, all at a target with a range that was greater than previous Blitzer firings. At the end of MFIX, GA-EMS’ Blitzer railgun system will be transported back to Dugway Proving Ground in Utah for more testing later this year.

GA-EMS’ Acoustic Detection System, an unattended ground sensor system for multi-target simultaneous detection and tracking, was also showcased at the MFIX event. The system can monitor multiple sensors simultaneously and enable visual detection and tracking of acoustic and seismic sources.

Impressive; and this is only what we know about the commercial market. Think about what this means to the black market and dark web’s trading sites.

Another question; how good are the forgeries? One that will be even more tricky with 3D. How do you know for sure you’re carrying a Hermes or wearing Chanel glasses or not. Not to mention art, etc.

The 3D printing industry is expected to triple its revenue mainly through the consumer electronics and automotive industries, each of which will contribute 20% of total revenue.

Google’s Project Soli was one of the highlights of the company’s developer conference last year, but there’s been little news about it since then.

The technology uses special radar-sensors packed in a tiny chip to detect a person’s physical movements (such as rubbing two fingers together), letting a person do things like turn the volume up on a radio without actual touching anything.

The recent news that Regina Dugan, the head of the Advanced Technology and Projects lab at Google that oversaw Soli, jumped ship to go work at rival Facebook, did not seem like a good sign for the future of Soli. And with Microsoft’s recent unveiling of similar technology, Google’s impressive product demo last year seemed like it might not make it out of the lab.

Using bacteria to aid in the design of superior biomedical implants capable of resisting colonization by infectious bugs.

Dr. Pushkar Lele, assistant professor in the Artie McFerrin Department of Chemical Engineering at Texas A&M University, is developing novel insights in cellular mechanics with bacteria to aid in the design of superior biomedical implants capable of resisting colonization by infectious bugs. Lele’s group also focuses on unraveling the fundamental principles underlying interactions in biological soft-matter to build bio-nanotechnology-based molecular machines. Lele’s lab currently focuses on a unique electric rotary device found in bacteria — the flagellar motor.

According to Lele, it is well established how motile bacteria employ flagellar motors to swim and respond to chemical stimulation. This allows bacteria to search for nutrients and evade harmful chemicals. However, in his recent work, Lele has now demonstrated that the motor is also sensitive to mechanical stimulation and identified the protein components responsible for the response. Sensing initiates a sensitive control of the assemblies of numerous proteins that combine to form the motor. Control over motor assemblies facilitates fine-tuning of cellular behavior and promotes chances of survival in a variety of environments.

“What is the sense of touch in a bacterium? It is likely that they employ appendages such as the flagella to detect solid substrates, analogous to our use of fingers,” Lele said. “How they recognize the substrate using the flagellum has been a long-standing question in biology with tremendous biomedical significance. Our findings have provided a handle on this important problem. We now know [how] the motor-components [are] involved in sensing the substrate [and] would like to know how these sensors trigger signaling networks that ultimately cause infections. “.
