Meet your virtual avatar: the future of personalized healthcare
ITU News – Tingly? Sharp? Electric? Dull? Pulsing?
Trying to describe a pain you feel to your doctor can be a difficult task. But soon, you won’t have to: a computer avatar is expected to tell your doctor everything they need to know.
The CompBioMed Centre of Excellence, an international consortium of universities and industries, is developing a program that creates a hyper-personalized avatar or ‘virtual human’ using a supercomputer-generated simulation of an individual’s physical and biomedical information for clinical diagnostics.
There is a rapid and growing need for this kind of technology-enabled healthcare. 12 million people who seek outpatient medical care in the U.S. experience some form of diagnostic error. Additionally, the World Health Organization estimates that there will be a global shortage of 12.9 million healthcare workers by 2035.
Greater access to technology-enabled healthcare will allow doctors to make better and faster diagnoses – and provide the tools to collect the necessary data.
The Virtual Human project combines different kinds of patient data that are routinely generated as part of the current healthcare system, such as x-rays, CAT scans or MRIs to create a personalized virtual avatar. more>

Tiny Vibration-Powered Robots Are the Size of the World’s Smallest Ant
By John Toon – Researchers have created a new type of tiny 3D-printed robot that moves by harnessing vibration from piezoelectric actuators, ultrasound sources or even tiny speakers. Swarms of these “micro-bristle-bots” might work together to sense environmental changes, move materials – or perhaps one day repair injuries inside the human body.
The prototype robots respond to different vibration frequencies depending on their configurations, allowing researchers to control individual bots by adjusting the vibration. Approximately two millimeters long – about the size of the world’s smallest ant – the bots can cover four times their own length in a second despite the physical limitations of their small size.
“We are working to make the technology robust, and we have a lot of potential applications in mind,” said Azadeh Ansari, an assistant professor in the School of Electrical and Computer Engineering at the Georgia Institute of Technology. “We are working at the intersection of mechanics, electronics, biology and physics. It’s a very rich area and there’s a lot of room for multidisciplinary concepts.”
A paper describing the micro-bristle-bots has been accepted for publication in the Journal of Micromechanics and Microengineering. The research was supported by a seed grant from Georgia Tech’s Institute for Electronics and Nanotechnology. In addition to Ansari, the research team includes George W. Woodruff School of Mechanical Engineering Associate Professor Jun Ueda and graduate students DeaGyu Kim and Zhijian (Chris) Hao. more>

How local productivity growth affects workers near and far
One city’s boom can be felt across a nation
Chicago Booth – When big cities experience an economic boom, you expect an upsurge in wages and growth in those areas. But there’s some nuance: according to Chicago Booth’s Richard Hornbeck and University of California at Berkeley’s Enrico Moretti, one area’s surge particularly benefits low-skilled workers locally—and high-skilled workers elsewhere.
Using total factor productivity (TFP) as a measure of local productivity growth, Hornbeck Amount and Moretti analyzed two decades of data from major US cities to quantify the direct effects on people living in booming cities and the indirect effects on people elsewhere. Allowing for trade-offs between salary and cost-of-living increases, as well as unequal distribution of benefits across different groups, the researchers find that low-skilled workers gained the most from local productivity growth.
But gains extended further afield: a boom in San Diego or Los Angeles, say, was also felt in other cities. And high-skilled workers gained more from productivity growth in other cities. more>

Signals from Distant Lightning Could Help Secure Electric Substations
By John Toon – Side channel signals and bolts of lightning from distant storms could one day help prevent hackers from sabotaging electric power substations and other critical infrastructure, a new study suggests.
By analyzing electromagnetic signals emitted by substation components using an independent monitoring system, security personnel could tell if switches and transformers were being tampered with in remote equipment. Background lightning signals from thousands of miles away would authenticate those signals, preventing malicious actors from injecting fake monitoring information into the system.
The research, done by engineers at the Georgia Institute of Technology, has been tested at substations with two different electric utilities, and by extensive modeling and simulation. Known as radio frequency-based distributed intrusion detection system (RFDIDS), the technique was described February 26 at the 2019 Network and Distributed System Security Symposium (NDSS) in San Diego.
“We should be able to remotely detect any attack that is modifying the magnetic field around substation components,” said Raheem Beyah, Motorola Foundation Professor in Georgia Tech’s School of Electrical and Computer Engineering and co-founder of Fortiphyd Logic, Inc. “We are using a physical phenomenon to determine whether a certain action at a substation has occurred or not.”
Opening substation breakers to cause a blackout is one potential power grid attack, and in December 2015, that technique was used to shut off power to 230,000 persons in the Ukraine. Attackers opened breakers in 30 substations and hacked into monitoring systems to convince power grid operators that the grid was operating normally. Topping that off, they also attacked call centers to prevent customers from telling operators what was happening. more>

By Sarah Garfinkel – When considering the senses, we tend to think of sight and sound, taste, touch and smell. However, these are classified as exteroceptive senses, that is, they tell us something about the outside world. In contrast, interoception is a sense that informs us about our internal bodily sensations, such as the pounding of our heart, the flutter of butterflies in our stomach or feelings of hunger.
The brain represents, integrates and prioritizes interoceptive information from the internal body. These are communicated through a set of distinct neural and humeral (ie, blood-borne) pathways. This sensing of internal states of the body is part of the interplay between body and brain: it maintains homeostasis, the physiological stability necessary for survival; it provides key motivational drivers such as hunger and thirst; it explicitly represents bodily sensations, such as bladder distension.
But that is not all, and herein lies the beauty of interoception, as our feelings, thoughts and perceptions are also influenced by the dynamic interaction between body and brain.
The shaping of emotional experience through the body’s internal physiology has long been recognized. The American philosopher William James argued in 1892 that the mental aspects of emotion, the ‘feeling states’, are a product of physiology. He reversed our intuitive causality, arguing that the physiological changes themselves give rise to the emotional state: our heart does not pound because we are afraid; fear arises from our pounding heart. more>
