Nuclear Nonproliferation, Cooperative Threat Reduction and WMD Terrorism — Dr. Natasha Bajema, Director, Converging Risks Lab, The Council on Strategic Risks.


Dr. Natasha Bajema, is a subject matter expert in nuclear nonproliferation, cooperative threat reduction and WMD terrorism, and currently serves as Director of the Converging Risks Lab, at The Council on Strategic Risks, a nonprofit, non-partisan security policy institute devoted to anticipating, analyzing and addressing core systemic risks to security in the 21st century, with special examination of the ways in which these risks intersect and exacerbate one another.

The Converging Risks Lab (CRL) is a research and policy development-oriented program designed to study converging, cross-sectoral risks in a rapidly-changing world, which brings together experts from multiple sectors of the security community, to ask forward-thinking questions about these converging risks, and to develop anticipatory solutions.

Dr. Bajema is also Founder and CEO of Nuclear Spin Cycle, a publishing and production company specializing in national security, entertainment, and publishing.

Prior to this, Dr. Bajema was at the Center for the Study of Weapons of Mass Destruction at the National Defense University, serving as Director of the Program for Emerging Leaders (PEL), as well as serving long-term detail assignments serving in various capacities in the Office of the Secretary of Defense, Acquisitions, Technology and Logistics, Nuclear, Chemical and Biological Defense Programs and in Defense Nuclear Nonproliferation at Department of Energy’s National Nuclear Security Administration.

Multi-resistant pathogens are a serious and increasing problem in today’s medicine. Where antibiotics are ineffective, these bacteria can cause life-threatening infections. Researchers at Empa and ETH Zurich are currently developing nanoparticles that can be used to detect and kill multi-resistant pathogens that hide inside our body cells. The team published the study in the current issue of the journal Nanoscale (“Inorganic nanohybrids combat antibiotic-resistant bacteria hiding within human macrophages”).

In the arms race “mankind against bacteria”, bacteria are currently ahead of us. Our former miracle weapons, antibiotics, are failing more and more frequently when germs use tricky maneuvers to protect themselves from the effects of these drugs. Some species even retreat into the inside of human cells, where they remain “invisible” to the immune system. These particularly dreaded pathogens include multi-resistant staphylococci (MRSA), which can cause life-threatening diseases such as sepsis or pneumonia.

ALEX, WHERE TO START?

**Engineers, using artificial intelligence and wearable cameras, now aim to help robotic exoskeletons walk by themselves.**

Increasingly, researchers around the world are developing lower-body exoskeletons to help people walk. These are essentially walking robots users can strap to their legs to help them move.

One problem with such exoskeletons: They often depend on manual controls to switch from one mode of locomotion to another, such as from sitting to standing, or standing to walking, or walking on the ground to walking up or down stairs. Relying on joysticks or smartphone apps every time you want to switch the way you want to move can prove awkward and mentally taxing, says Brokoslaw Laschowski, a robotics researcher at the University of Waterloo in Canada.


AI and wearable cameras could help exoskeletons act a bit like autonomous vehicles.

Continuous and controlled shape morphing is essential for soft machines to conform, grasp, and move while interacting safely with their surroundings. Shape morphing can be achieved with two-dimensional (2D) sheets that reconfigure into target 3D geometries, for example, using stimuli-responsive materials. However, most existing solutions lack the ability to reprogram their shape, face limitations on attainable geometries, or have insufficient mechanical stiffness to manipulate objects. Here, we develop a soft, robotic surface that allows for large, reprogrammable, and pliable shape morphing into smooth 3D geometries. The robotic surface consists of a layered design composed of two active networks serving as artificial muscles, one passive network serving as a skeleton, and cover scales serving as an artificial skin.
