Interesting.

Although E. coli bacteria is often considered as a bad bug, laboratory-adapted E. coli that do not harm human beings and can multiply fast have been commonly used for various research purposes.

The same property allows the bacteria to rebuild into the smallest of factories when their chemical producing ability is utilized. E. coli possesses the ability to crank out pharmaceuticals, biofuels, and various other useful products.

Currently, a team of researchers from the School of Engineering & Applied Science at Washington University have developed a technique to efficiently produce biofuels in certain E. coli. Fuzhong Zhang, assistant professor in the Department of Energy, Environmental & Chemical Engineering, accompanied by other researchers, has discovered a new method that will eliminate a major hurdle in the production process.

I know so many people who will benefit from this.

During the 2014 FIFA World Cup opening ceremony, a young Brazilian man, paralyzed from the chest down, delivered the opening kickoff. He used a brain-machine interface, allowing him to control the movements of a lower-limb robotic exoskeleton.

This unprecedented scientific demonstration was the work of the Walk Again Project (WAP), a nonprofit, international research consortium that includes Alan Rudolph, vice president for research at Colorado State University, who is also an adjunct faculty member at Duke University’s Center for Neuroengineering.

Barely two years after the demonstration, the WAP has released its first clinical report, published Aug. 11 in Scientific Reports. They report that a group of patients who trained throughout 2014 with the WAP’s brain-controlled system, including a motorized exoskeleton, have regained the ability to voluntarily move their leg muscles and to feel touch and pain in their paralyzed limbs. This, despite being originally diagnosed as having a clinically complete spinal cord injury — in some cases more than a decade earlier.

I never get tired of talking about the many uses for Q-dot technology. One area that has me even more intrigued is how it is used in crystallized formations. I expect to see more and more experimenting on crystalized formations on many fronts including complex circuitry for performance and storage.

And, with synthetic technology today plus 3D printing along with Q-dots we could (as I have eluded to many times over several months) truly begin to see some amazing technology be developed on the wearable tech front.

Wearables could include synthetic circuitry stones in various accessories to not only store information, but also serve as another form of unique id because in synthetic stones we have been able (like in nature) create complex crystalized formations that are each unique/ 1 of a kind like a unique finger print, or iris of an eye. I expect to see some very interesting things coming in this space.

Unique optical features of quantum dots make them an attractive tool for many applications, from cutting-edge displays to medical imaging. Physical, chemical or biological properties of quantum dots must, however, be adapted to the desired needs.

In a set of studies in mice bearing human tumors, nanoparticles designed to bind to a protein called P-selectin successfully delivered both chemotherapy drugs and targeted therapies to tumor blood vessels. Targeting the blood vessels improved the delivery of drugs to tumor tissue, causing the tumors to shrink and improving how long the mice lived.

A tumor’s blood vessels can serve as a barrier to engineered drug-delivery systems like nanoparticles, which may not be able to cross the blood vessel wall. However, the same blood vessels may express proteins—such as P-selectin—that researchers can potentially exploit, by engineering their nanoparticles to recognize and latch onto those proteins, which enables them to reach the tumor.

This is a comprehensive and critical write-up on some of my policies by some leading researchers and thinkers. It’s from the magazine website of the IEEE, the world’s largest professional organization devoted to engineering and the applied sciences. Naturally, people in the field of science and engineering are some of the most difficult to please, since they are such critical thinkers (which is precisely why I like them so much):

Half quad-copter and 1/2 missile.

The design of small UAVs usually falls into one of two categories: the cruciform quadcopter (with extra arms added as necessary) and the fixed-wing glider (such as early iterations of Google’s delivery drones). However, there’s still room for innovation in this market, as demonstrated by the QuadRKT: a quadcopter drone with a rocket-shaped fuselage that can hovers vertically, but also switch to a horizontal orientation when it needs to go really fast.

The QuadRKT’s basic design has been around for a few years, but its creators are now looking to raise funds on Kickstarter for further development. The team originally developed prototypes of the design (then known as the XQ-139 family of aircraft) for DARPA’s Experimental Vertical Takeoff and Landing program. The US agency reportedly declared the QuadRKT “too risky” to build, and the drone’s creators — a team of engineering and aerospace experts — are now trying to make their design a commercial reality by themselves.

WOW — now that’s an engineering feat.

While Dubai is keen to become a 3D printing world leader with their Dubai 3D Printing Strategy, they are by no means the only Middle Eastern nation to look into this technology. Last week a delegation of Chinese WinSun officials traveled to Riyadh, the capital of the Kingdom of Saudi Arabia, to discuss construction 3D printing. Among others, the Chinese construction 3D printing pioneers were invited to 3D print up to 1.5 million housing units over the next five years.

WinSun is the company that made construction 3D printing a practical reality. Back in 2014, the Shanghai-based company created headlines all over the internet for building not one, but ten 3D printed houses in less than 24 hours. Since then, Shanghai WinSun Decoration Design Engineering Co., to give its full name, has been building on that initial achievement with one 3D printed concrete creation after another. Back in March, they even unveiled two gorgeous 3D printed Chinese courtyards.

Smart bricks capable of recycling wastewater and generating electricity from sunlight are being developed by a team of scientists from the University of the West of England (UWE Bristol). The bricks will be able to fit together and create ‘bioreactor walls’ which could then be incorporated in housing, public building and office spaces.

The UWE Bristol team is working on the smart technologies that will be integrated into the in this pan European ‘Living Architecture’ (LIAR) project led by Newcastle University. The LIAR project brings together living architecture, computing and engineering to find a new way to tackle global sustainability issues.

The smart living bricks will be made from bio-reactors filled with microbial cells and algae. Designed to self-adapt to changing environmental conditions the smart bricks will monitor and modify air in the building and recognise occupants.
