TRUTH DECAYTechnology Can Detect Fake News in Videos
Social media represent a major channel for the spreading of fake news and disinformation. This situation has been made worse with recent advances in photo and video editing and artificial intelligence tools, which make it easy to tamper with audiovisual files, for example with so-called deepfakes, which combine and superimpose images, audio and video clips to create montages that look like real footage.

COASTAL CHALLENGESDeveloping Novel Hybrid Reef-Mimicking Structures
Despite previous efforts to implement storm mitigation solutions — including concrete breakwaters — damage due to storm surge and flooding continues to devastate coastal areas around the world. In response to these threats, DARPA has launched the Reefense program to develop self-healing, hybrid biological, and engineered reef-mimicking structures to protect civilian and DoD infrastructure, personnel by mitigating damage related to coastal flooding, erosion and storm surge.

ARGUMENT: AI & NATIONAL SECURITY Preparing National Security Officials for the Challenges of AI
Artificial intelligence (AI) is one of several rapidly emerging technologies that promise to disrupt not only multiple sectors of the U.S. economy but also the manner in which the U.S. government carries out its foundational responsibility to protect national security consistent with the rule of law and constitutional values. Steve Bunnell writes that “The United States’ national security apparatus is not known for nimbleness, nor is the law that governs it. When it comes to AI, the risk is not just that our generals will fight tomorrow’s war with yesterday’s strategy but also that the United States will lack the legal and policy guardrails that are essential to a lawful, accountable, and ethical protection of the nation’s security.”

GRID PROTECTIONCybersecurity Tools to Protect Solar, Wind Power on the Grid
Solar panels and wind turbines are projected to produce 44% of America’s electricity by 2050, but they present cybersecurity challenges. They have sensors, controllers, actuators or inverters which are directly or indirectly connected to the internet using insecure connectivity to legacy electric grid systems. They have complex physics. They’re subject to advanced persistent threats. And there will be more and more of them going online.

AIThe Civil-Military Divide over Artificial Intelligence
What factors influence how comfortable and uncomfortable software engineers feel with potential applications of AI for the U.S. military? Is there a correlation between the degree of trust that software engineers have in societal institutions—specifically, in DoD—and their perception of the acceptability of building AI applications for DoD? Do software engineers perceive the countries that DoD has identified as strategic competitors as a meaningful threat to the United States? What types of news media and other sources of information are software engineers relying on to inform them about events related to DoD?
