Material formed from crab shells and trees could replace flexible plastic packaging

Posted by in categories: chemistry, engineering, food, sustainability

From liquid laundry detergent packaged in cardboard to compostable plastic cups, consumer products these days are increasingly touting their sustainable and renewable origins.

Now researchers at Georgia Institute of Technology have created a material derived from crab shells and tree fibers that has the potential to replace the flexible used to keep food fresh.

The new material, which is described July 23 in the journal ACS Sustainable Chemistry and Engineering, is made by spraying multiple layers of chitin from crab shells and cellulose from trees to form a flexible film similar to plastic packaging film.

Team suggests a way to protect autonomous grids from potentially crippling GPS spoofing attacks

Posted by in categories: biotech/medical, cybercrime/malcode, drones, engineering, internet, robotics/AI

Not long ago, getting a virus was about the worst thing computer users could expect in terms of system vulnerability. But in our current age of hyper-connectedness and the emerging Internet of Things, that’s no longer the case. With connectivity, a new principle has emerged, one of universal concern to those who work in the area of systems control, like João Hespanha, a professor in the departments of Electrical and Computer Engineering, and Mechanical Engineering at UC Santa Barbara. That law says, essentially, that the more complex and connected a system is, the more susceptible it is to disruptive cyber-attacks.

“It is about something much different than your regular computer virus,” Hespanha said. “It is more about cyber physical systems—systems in which computers are connected to physical elements. That could be robots, drones, smart appliances, or infrastructure systems such as those used to distribute energy and water.”

In a paper titled “Distributed Estimation of Power System Oscillation Modes under Attacks on GPS Clocks,” published this month in the journal IEEE Transactions on Instrumentation and Measurement, Hespanha and co-author Yongqiang Wang (a former UCSB postdoctoral research and now a faculty member at Clemson University) suggest a new method for protecting the increasingly complex and connected power grid from attack.

Akka pod with detachable wings would integrate aviation with public transit

Posted by in categories: engineering, transportation

Akka Technologies is developing pods with detachable wings that would integrate aviation and public transit. The AKKA Group is an engineering and technology consulting company with 16000 employees.

The detachable wings would make for vastly more efficient boarding and improve the utilization of the engines and wings.

The Father of the Big Bang Theory

Posted by in categories: cosmology, engineering, military, particle physics

Monsignor Georges Lemaître was a Belgian Roman Catholic priest, physicist and astronomer. He is usually credited with the first definitive formulation of the idea of an expanding universe and what was to become known as the Big Bang theory of the origin of the universe, which Lemaître himself called his “hypothesis of the primeval atom” or the “Cosmic Egg”.

Georges Henri Joseph Édouard Lemaître was born on 17 July 1894 at Charleroi, Belgium. After a classical education at a Jesuit secondary school, the Collège du Sacré-Coeur in Charleroi, he began studying civil engineering at the Catholic University of Leuven (Louvain) at the age of 17. In 1914, he interrupted his studies to serve as an artillery officer in the Belgian army for the duration of World War I, at the end of which he received the Military Cross with palms.

How the Second Amendment Turned Into Freedom of Information Thanks to 3D Printing

Posted by in categories: 3D printing, engineering

The power of 3D printing has opened up a whole new mode of “imagination engineering.” The world of tomorrow’s weapons and ammunition are going to be radically different from what we consider weapons and ammunition today.


Now that Defense Distributed has won their court case, officially legalizing 3D-printable gun uploads and downloads, how will the future respond to today’s gun laws?

Carbon nanotubes used to develop clothing that can double as batteries

Posted by in categories: engineering, military, nanotechnology

Move over, Iron Man.

What makes this possible are the unique properties of carbon nanotubes: a large surface area that is strong, conductive and heat-resistant.

UC’s College of Engineering and Applied Science has a five-year agreement with the Air Force Research Laboratory to conduct research that can enhance military technology applications.

‘Blind’ Cheetah 3 robot can climb stairs littered with obstacles

Posted by in categories: engineering, robotics/AI

The 90-pound mechanical beast — about the size of a full-grown Labrador — is intentionally designed to do all this without relying on cameras or any external environmental sensors. Instead, it nimbly “feels” its way through its surroundings in a way that engineers describe as “blind locomotion,” much like making one’s way across a pitch-black room.

“There are many unexpected behaviors the robot should be able to handle without relying too much on vision,” says the robot’s designer, Sangbae Kim, associate professor of mechanical engineering at MIT. “Vision can be noisy, slightly inaccurate, and sometimes not available, and if you rely too much on vision, your robot has to be very accurate in position and eventually will be slow. So we want the robot to rely more on tactile information. That way, it can handle unexpected obstacles while moving fast.”

Researchers will present the robot’s vision-free capabilities in October at the International Conference on Intelligent Robots, in Madrid. In addition to blind locomotion, the team will demonstrate the robot’s improved hardware, including an expanded range of motion compared to its predecessor Cheetah 2, that allows the robot to stretch backwards and forwards, and twist from side to side, much like a cat limbering up to pounce.
