Ultra low-power wireless communication through the human body using magnetic fields

By - September 1, 2015 2 Pictures
Be it on the inside or the outside, the human body is becoming host to an ever-increasing array of electronic devices that need to wirelessly communicate with each other. Now engineers working at the University of California, San Diego (UCSD) have come up with a different type of wireless communication that sends ultra low-power magnetic fields through the human body. This makes it extraordinarily more energy efficient and secure from prying eyes than comparable wireless communication technologies. Read More

New "smart window" material selectively blocks light and/or heat

By - July 24, 2015 2 Pictures

In an effort to improve the energy efficiency of building, researchers have sought to develop windows that change transparency to let more light – and therefore heat – through when it's cold, and less when it's hot. Unfortunately, these methods tend to impede the passage of visible light, some by tinting panes and others by complete obscuration. But a team at the Cockrell School of Engineering at The University of Texas at Austin has developed a "smart window" technology that allows the passage of visible light while blocking heat, or vice versa.

Muscle injection could help burn more calories during routine activities

By - February 27, 2015
The future of weight loss could look like this. Inject your muscles with a compound that helps them burn more calories than usual and then do your daily chores to shed those extra pounds. That's the vision of a team of scientists who are working on a muscle-targeted injection therapy to help overweight people lose weight easily, even with low to moderate exercise. Read More

Changing instructions to make robot joints more energy efficient

By - July 7, 2014
Getting robots to carry out repetitive tasks precisely and untiringly is relatively easy. Getting them to do it in the most efficient way possible is another thing entirely. Unai Ugalde-Olea, lecturer in the Department of Electronics Technology of the UPV/EHU-University of the Basque Country is working on a new way of controlling robot joints that promises energy savings of up to 40 percent by changing the way the robot handles instructions.

Casa GG displays a considered approach to energy-efficiency

By - June 5, 2014 35 Pictures
Spain's Alventosa Morell Arquitectes recently completed work on a prefabricated energy-efficient residence that's located in the Montseny mountain range, to the north-west of Barcelona. Named Casa GG, the home was built in just four months – however this fact belies the impressive effort that went into studying how best to minimize energy-use before construction even began.

"Neurogrid" circuit modeled on the human brain is the fastest, most energy efficient of its kind

By - May 2, 2014 4 Pictures
A group of engineers at Stanford have developed an iPad-sized, highly power-efficient way of simulating a million neurons and billions of synapses for as low as US$400. The advancement could both help our understanding of the brain and help develop a new generation of bionic limbs that are controlled by the patient's brain in real time with no effort at all.
