Growing Pile of Human and Animal Waste Harbors Threats, Opportunities
By Josh Brown – As demand for meat and dairy products increases across the world, much attention has landed on how livestock impact the environment, from land usage to greenhouse gas emissions.
Now researchers at Georgia Institute of Technology and the Centers for Disease Control and Prevention are highlighting another effect from animals raised for food and the humans who eat them: the waste they all leave behind.
In a paper published November 13 in Nature Sustainability, the research team put forth what they believe is the first global estimate of annual recoverable human and animal fecal biomass. In 2014, the most recent year with data, the number was 4.3 billion tons and growing, and waste from livestock outweighed that from humans five to one at the country level.
“Exposure to both human and animal waste represent a threat to public health, particularly in low-income areas of the world that may not have resources to implement the best management and sanitation practices,” said Joe Brown, an assistant professor in Georgia Tech’s School of Civil and Environmental Engineering. “But estimating the amount of recoverable feces in the world also highlights the enormous potential from a resource perspective.” more>

Finally, a Robust Fuel Cell that Runs on Methane at Practical Temperatures
By Ben Brumfield – Fuel cells have not been particularly known for their practicality and affordability, but that may have just changed. There’s a new cell that runs on cheap fuel at temperatures comparable to automobile engines and which slashes materials costs.
Though the cell is in the lab, it has high potential to someday electrically power homes and perhaps cars, say the researchers at the Georgia Institute of Technology who led its development. In a new study in the journal Nature Energy the researchers detailed how they reimagined the entire fuel cell with the help of a newly invented fuel catalyst.
The catalyst has dispensed with high-priced hydrogen fuel by making its own out of cheap, readily available methane. And improvements throughout the cell cooled the seething operating temperatures that are customary in methane fuel cells dramatically, a striking engineering accomplishment. more>

Looking Back in Time to Watch for a Different Kind of Black Hole
By John Toon – Black holes form when stars die, allowing the matter in them to collapse into an extremely dense object from which not even light can escape. Astronomers theorize that massive black holes could also form at the birth of a galaxy, but so far nobody has been able to look far enough back in time to observe the conditions creating these direct collapse black holes (DCBH).
The James Webb Space Telescope, scheduled for launch in 2021, might be able look far enough back into the early Universe to see a galaxy hosting a nascent massive black hole. Now, a simulation done by researchers at the Georgia Institute of Technology has suggested what astronomers should look for if they search the skies for a DCBH in its early stages.
DCBH formation would be initiated by the collapse of a large cloud of gas during the early formation of a galaxy, said John H. Wise, a professor in Georgia Tech’s School of Physics and the Center for Relativistic Astrophysics. But before astronomers could hope to catch this formation, they would have to know what to look for in the spectra that the telescope could detect, which is principally infrared.
Black holes take about a million years to form, a blip in galactic time. In the DCBH simulation, that first step involves gas collapsing into a supermassive star as much as 100,000 times more massive than our sun. The star then undergoes gravitational instability and collapses into itself to form a massive black hole. Radiation from the black hole then triggers the formation of stars over period of about 500,000 years, the simulation suggested. more>

How AI for healthcare can overcome obstacles and save lives
By Dr. Winnie Tang – Al has been widely applied in healthcare. It can identify early symptoms, diagnose diseases, help carry out operations, predict when an epidemic will break out and undertake hospital administrative tasks such as making appointments and registering patients.
Accenture, a consultancy firm, estimated that 10 promising Al applications could save up to USD 150 billion in annual medical expenses for the U.S. by 2026.
Among the 10 applications, the most valuable is the robot-assisted surgery, according to the research. A study of 379 patients who had undergone orthopedic surgeries found that an AI-assisted robotic technique resulted in a five-fold reduction in the complications compared to operations performed solely by human surgeons. more>

How Digital Textile Designers Make Wearable Art
Adobe – Thanks to digital design tools, textile design is experiencing something of a renaissance. The field attracts graphic designers and illustrators because it employs many techniques they are already familiar with, but it enables visual thinkers to expand beyond the page and the screen. Fabric offers new opportunities and challenges with designs that move, flutter, and twirl along with their wearers.
In addition, some creatives see designing textiles as a way to make the switch from corporate design to crafting objects that are more personal. Clothes have the power to be more abstract and intimate than many client-based assignments.
For her part, Kaylan K. turned to drawing at the age of six to cope with “a very traumatic childhood” in Montreal.
“Art was my way of escaping all of this trauma around me and putting my energy into something that makes me feel alive,” she explains. more>

By Pete Singer – Dr. John E. Kelly, III, Senior Vice President, Cognitive Solutions and IBM Research, with 40 years of experience in the industry, recalled how the first era of computing began with mechanical computers 100 years ago, and then transition into the programmable era of computing.
In 1980, Kelly said “we were trying to stack two 16 kilobis DRAMs to get a 32 bit stack and we were trying to cram a thousand transistors into a microprocessor.” Microprocessors today have 15 billion transistors. “It’s been a heck of a ride,” he said.
A third exponential is now upon us, Kelly said. “The core of this exponential is that data is doubling every 12 to 18 months. In fact, in some industries like healthcare, data is doubling every six months,” he said.
The challenge is that the data is useless unless it can be analyzed. “Our computers are lousy in dealing with that large unstructured data and frankly there aren’t enough programmers in the world to deal with that explosion of data and extract value,” Kelly said. “The only way forward is through the use of machine learning and artificial intelligence to extract insights from that data.”
Quantum computing, which Kelly describe as a fourth exponential, is also coming which will in turn dwarf all of the previous ones. “Beyond AI, this is going to be the most important thing I’ve ever seen in my career. Quantum computing is a complete game changer,” he said. more>

GSR-18 BEST PRACTICE GUIDELINES ON NEW REGULATORY FRONTIERS TO ACHIEVE DIGITAL TRANSFORMATION
itu.int – Digitization is increasingly and fundamentally changing societies and economies and disrupting many sectors in what has been termed the 4th Industrial Revolution. Meanwhile, ICT regulation has evolved globally over the past ten years and has experienced steady transformation.
As regulators, we need to keep pace with advances in technology, address the new regulatory frontiers and create the foundation upon which digital transformation can achieve its full potential. Being prepared for digital transformation and emerging technologies such as Artificial Intelligence (AI), the Internet of Things (IoT), Machine to Machine communications (M2M) and 5G is fundamental.
Advances in technology are creating new social phenomena and business models that impact every aspect of our personal and professional lives – and which challenge regulatory paradigms. M2M, cloud computing, 5G, AI and IoT are all bringing further profound change. Recognizing the potential of emerging technologies and the impact that policy and regulatory frameworks can have on their success, regulators should encourage a regulatory paradigm pushing frontiers and enabling the digital transformation. more> draft doc (pdf)

Gridlock: Why Global Cooperation is Failing when We Need It Most, Authors: Thomas Hale, David Held, Kevin Young.
By David Held – The crisis of contemporary democracy has become a major subject of political commentary. But the symptoms of this crisis, the vote for Brexit and Trump, among other things, were not foreseen. Nor were the underlying causes of this new constellation of politics.
The virtuous circle between deepening interdependence and expanding global governance could not last because it set in motion trends that ultimately undermined its effectiveness.
There are four reasons for this or four pathways to gridlock: rising multipolarity, harder problems, institutional inertia, and institutional fragmentation. Each pathway can be thought of as a growing trend that embodies a specific mix of causal mechanisms.
To manage the global economy, reign in global finance, or confront other global challenges, we must cooperate. But many of our tools for global policy making are breaking down or prove inadequate – chiefly, state-to-state negotiations over treaties and international institutions – at a time when our fates are acutely interwoven.
The result is a dangerous drift in global politics punctuated by surges of violence and the desperate movement of peoples looking for stability and security. more>
