  • Chemical robot shows possibility of electronics-free robots

    The Belousov-Zhabotinsky (BZ) reaction is one of a class of chemical systems in which the concentration of one or more compounds periodically increases and decreases; the oscillation thus generated creates an autonomous material that moves without electronic stimulation; door opens for future chemical robots: they will be “self organized” and generate their own control and mechanical signals from within

  • New sensor system protects ports, bridges, and distribution centers

    Sensor networks are an efficient, cost-effective way to monitor critical infrastructure facilities, distributions centers, and more; trouble is, to work effectively you need a very large number of them, and they all have to work collaboratively; a Dutch university researcher offers a better way of achieving this

  • Policy Approaches to Climate Migration: Lessons from Latin America and the Caribbean

    As climate change has gained more attention and governments have developed policies to reduce carbon emissions and manage increasing environmental risks, climate migration—the movement of people primarily due to changes in the environment that result from climate change—has become a key issue for research and policy.

  • How Easy Is it to Build a Robot Assassin?

    Someone—almost certainly Israel—recently assassinated Mohsen Fakhrizadeh, the leading scientist behind the Iranian nuclear program. The latest reporting from Iran suggests that the assassins employed a remotely controlled machine gun mounted on a pickup truck. So how hard is it to build such a tool? How expensive? Nicholas Weaver writes that “Unfortunately, the answer is “hard but doable” and “not much money”—with the further complication that in a few years, it will probably be possible to pick up the necessary equipment online from vendors like Banggood.”

  • Help Wanted: The Cybersecurity Workforce of the Future Starts with Students Today

    Today’s critical infrastructure systems from farm fields planted with digital sensors that track soil moisture and nutrient levels to electric power grids equipped to instantly respond to digital signals about shifts in supply and demand are increasingly vulnerable to attacks that could cripple civil society, according to cybersecurity experts. Today, there are nearly 2 million U.S. job openings in the field of cybersecurity, studies indicate.

  • Study Identifies Reasons for Soaring Nuclear Plant Cost Overruns in the U.S.

    Analysis points to ways engineering strategies could be reimagined to minimize delays and other unanticipated expenses. Many analysts believe nuclear power will play an essential part in reducing global emissions of greenhouse gases, and finding ways to curb these rising costs could be an important step toward encouraging the construction of new plants.

  • Guidance Will Improve Critical Infrastructure Resilience

    It is easy to understand the importance of our “critical infrastructure,” such as telecommunications, energy, transportation, and emergency services, but what’s often overlooked are the underlying technologies that enable them. DHS S&T is doing something about it.

  • The Nashville Bombing and Threats to Critical Infrastructure: We Saw This Coming

    If fear of 5G technology proves to be the motive for the Christmas-Day bombing in Nashville, Tennessee, no one should be surprised. Audrey Kurth Cronin writes that if [Nashville bomber] Anthony Warner was indeed protesting 5G networks, it shines a light on the long-standing need for U.S. intelligence and law enforcement to meld global and local efforts to get ahead of cyber-driven threats to critical infrastructure. “Authorities need to strengthen their ability to meet anti-technology attacks on our vulnerable critical infrastructure, especially by looking close to home.”
