The environmental costs of moving data around the world or building a better smartphone often go unappreciated. Both tasks take a great deal of energy and other resources, though the effects are often felt hundreds or thousands of miles from most end users. The world's biggest technology firms are increasingly focused on finding ways to go green. Facebook announced in January that it is building a new data center in Ireland powered entirely by renewable energy. In March, Apple introduced a recycling robot named "Liam" that can surgically disassemble old iPhones so their parts can be reused.

Iran concluded a major, three-day military exercise Friday intended to review the readiness of its armed forces. The drills, called "Great Prophet," also field-tested new military technology, including the Iranian-made Karrar tank and the Hamasseh drone, Middle East Monitor reported. The Iranian air force, elite units and local forces were involved in the exercise. The drills covered four provinces in Iran's southeast region near the border with Pakistan. The exercises came amid growing tensions in the area over the protracted civil war in Syria and the threat posed by the Islamic State group, also known as ISIS.

Yemeni government troops newly-trained by a Saudi-led coalition battling Yemen's Shiite rebels routed al-Qaida militants on Friday from a city in the country's south, military officials said. Houta, the capital of Lahj province, is now firmly under government control, the officials said. The coalition-trained troops, which are loyal to Yemen's internationally recognized government, were based in the southern Al-Anad base from where they launched the fight to retake the provincial capital, they added. The officials said the militants fled on Friday from Houta to nearby towns and farmland. The assault came at a time the coalition helicopters and U.S. drones have waged series of airstrikes targeting al-Qaida hideouts and strongholds across Yemen's southern region.

Stocks turned lower on the Tokyo Stock Exchange Friday, pressured by selling on a rally after the recent sharp advance. The 225-issue Nikkei average lost 63.02 points, or 0.37 percent, to end at 16,848.03. On Thursday, the key market gauge jumped 529.83 points to a two-week high. The Topix index of all first-section issues finished down 9.95 points, or 0.73 percent, at 1,361.40, after advancing 38.91 points the previous day. Tokyo stocks got off to a weaker start after the Nikkei average shot up more than 1,100 points, or over 7 percent, during the previous three days.

Outcome expected on October 21, 2045.

The Journalism Department at Emerson College and the Emerson Engagement Lab recently invited William Li to give a talk to introduce machine learning to journalism and communications students. This is a live blog account of the talk by Catherine D'Ignazio. William Li is a 2015–2016 Fellow at the Harvard University Berkman Center for Internet and Society and a 2016 PhD computer science graduate from MIT. He develops and applies machine learning methods to answer social science questions computationally and to promote public understanding of law, politics, and public policy. His projects include predicting the authors of unsigned Supreme Court opinions, visualizing the complexity of our laws, and discovering ideas from large collections of public comments on proposed regulations. William has also worked on recommender systems, speech recognition, and user activity prediction at Apple and Mitsubishi Electric. He did his master's degrees at MIT in computer science and the Technology and Policy Program, founded the MIT Assistive Technology Club, and has taught classes that involve civic collaborations with organizations such as the Massachusetts Committee for Public Counsel Services, Greater Boston Legal Services, and the Cambridge Commission for People with Disabilities. William Li introduces the topic and that he wants to make the session very interactive.

The biggest leak in history has connected more than 70 current and former world leaders to tax evasion schemes that channel billions of pounds into secretive off-shore accounts. This is how the data was analysed. The Panama Papers show that law firm Mossack Fonseca helped hundreds of clients, with connections to some of the most powerful people in the world, launder money, dodge tax and potentially avoid sanctions. The papers themselves were leaked to news organisations by an unknown person and have been shared with more than 100 news organisations and 400 journalists – the investigation has been ongoing for almost a year. The process of making the raw data accessible for journalists involved converting it to digital formats, high-performance computers, and algorithms to find well known names among the thousands of details. While the actual leaked documents have not been published -– the International Consortium of Investigative Journalists (ICIJ) say the full list of companies linked to the papers will be revealed in May – how much data they contain is known.

Called "Deep learning" in the industry, artificial intelligence can be used to create profiles of its users and signal alerts when deviations occur. Security professionals are not saying that human intervention is no longer necessary. While machines can read and analyze data, humans should still intervene to interpret the data to determine if there is indeed an existential threat to the network. In the case of a potential breach, AI can shut systems down preventing malware from getting deep into the network and raise security alerts to the professionals for further investigation. It creates the opportunity for organizations to fix problems before they become too expensive or widespread. Global Data Sentinel uses AI to detect suspicious behavior automatically, based on its ability to learn from previous user behavior.

"Advanced cyberlearning environments that involve Virtual Reality and Artificial Intelligence innovations are becoming powerful tools that can facilitate the explorations and conversations needed to solve society's "wicked challenges," said Winslow Burleson, PhD, MSE, an engineer by training and currently associate professor, New York University Rory Meyers College of Nursing. The researchers posit that the use of technology, specifically a bundled and ever-evolving fluid set of integrated cyber tools, will connect disparate groups and individuals, converging them in both a real and an imagined cyber-social-physical environment, called the Holodeck, that Burleson's NYU-X Lab is currently advancing in prototype form, in close collaboration with colleagues at NYU Courant, Tandon, Steinhardt, and Tisch, "The "Holodeck" will support a broad range of transdisciplinary collaborations, integrated education, research, and innovation by providing a networked software/hardware infrastructure that can synthesize visual, audio, physical, social, and societal components," said Burleson. NYU-X Lab's Holodeck prototype harnesses the collective power of shared computation, integrated distributed data, immersive visualization, and social interaction to make possible large-scale synthesis of learning, research, and innovation, that will dramatically accelerate the Rittel and Webber iterative mode of problem solving. The goal is to create a networked infrastructure and communication environment where "wicked challenges" can be iteratively explored and re-solved, utilizing visual, acoustic, and physical sensory feedback, human dynamics with and social collaboration.

In the late 1960s, urban planners Horst Rittel and Melvin Webber began formulating the concept of "wicked problems" or "wicked challenges" --problems so vexing in the realm of social and organizational planning that they could not be successfully ameliorated with traditional linear, analytical, systems-engineering types of approaches. These "wicked challenges" are poorly defined, abstruse, and connected to strong moral, political and professional issues. Some examples might include: "How should we deal with crime and violence in our schools? "How should we wage the'War on Terror'? or "What is good national immigration policy?" "Wicked problems," by their very nature, are strongly stakeholder dependent; there is often little consensus even about what the problem is, let alone how to deal with it.
