The Homeland Defense (HD) Digest is a curated bi-weekly news summary from worldwide sources, showing headlines of innovative, emerging technologies in HDIAC's eight focus areas.
The HDIAC Podcast – Rethinking Culture in the Context of Civil-Military Relations – Part 3 of 3 - HDIAC
In the third installment of Rethinking Culture in the Context of Civil-Military Relations, Dr. Zoli and Dr. Rubinstein continue the conversation around different cultural models of risk and security and discuss the broader impacts of taking a militarized approach to security abroad.
HDIAC Webinar, Wednesday, Feb 26th @ 1200 EST: Critical Infrastructure Resilience through Communication, Coordination, and Collaboration - HDIAC
This presentation focuses on the role of communication, coordination, and collaboration for critical infrastructure resilience. The webinar will discuss the increasing importance of multi-stakeholder partnerships - across the public, private, and academic sectors - in promoting resilience within and across the four major increasingly interdependent critical infrastructure systems: energy, transportation, water, and communications.
Iodide Salts Stabilize Bio-catalysts for Fuel Cells - ScienceDaily
Contrary to theoretical predictions, oxygen inactivates bio-catalysts for energy conversion within a short time, even under a protective film. A research team has found out why: Hydrogen peroxide forms on the protective film. The addition of iodide salts to the electrolyte can prevent this from happening and considerably extend the life of the catalysts.
5200-Year-Old Grains in the Eastern Altai Mountains Redate Trans-Eurasian Crop Exchange - ScienceDaily
Cereals from the Fertile Crescent and broomcorn millet from northern China spread across the ancient world, integrating into complex farming systems that used crop-rotation cycles enabled by the different ecological regions of origin. The resulting productivity allowed for demographic expansions and imperial formation in Europe and Asia. In this study, scientists illustrate that people moved these crops across Eurasia earlier than previously realized, adapting cultivation methods for harsh agricultural environments.
Computer-Generated Genomes - ScienceDaily
Chemists have described how computational algorithms paired with chemical DNA synthesis enable digital manufacturing of biological systems up to the size of entire microbial genomes. They have made insights related to the design, building and testing of a computer-generated bacterial genome and can discuss how algorithms simplify the synthesis of genomes to advance understanding of living systems.
New Green Technology Generates Electricity ‘Out of Thin Air’ - ScienceDaily
Electrical engineers and microbiologists have created a device they call an 'Air-gen.' or air-powered generator, with electrically conductive protein nanowires produced by the microbe Geobacter. The Air-gen connects electrodes to the protein nanowires in such a way that electrical current is generated from the water vapor naturally present in the atmosphere.
Coronavirus: We Need to Start Preparing for the Next Viral Outbreak Now - Homeland Security
The coronavirus outbreak is officially a crisis - let's not waste it. Undeniably, the international community is taking the matter very seriously, as it should, given that the death total from the COVID-19 epidemic already well surpasses that from SARS in the early 2000s. However, even if the international response to COVID-19 has been relatively strong, it may rightfully be considered too little too late, with the epidemic already underway. That's a mistake we shouldn't repeat. As global health researchers, we study the full societal value of vaccination and other interventions to combat infectious disease. Given the tremendous costs associated with epidemics, it's vital that we begin working to prevent the next outbreak, even as the world struggles to fight COVID-19.
The latest proposed bone regenerative therapy is a paint-like substance that coats implants or other devices to promote bone regrowth. It's designed for use in treating combat injuries and lower back pain, among other issues.

Mixed-Signal Hardware Security Thwarts Powerful Electromagnetic Attacks - Homeland Security
Security of embedded devices is essential in today's internet-connected world. Security is typically guaranteed mathematically using a small secret key to encrypt the private messages. When these computationally secure encryption algorithms are implemented on a physical hardware, they leak critical side-channel information in the form of power consumption or electromagnetic radiation. Now, researchers have developed technology to kill the problem at the source itself - tackling physical-layer vulnerabilities with physical-layer solutions.
Qualcomm Helps German Startup Sell its Skin-Sensing Liveness Sensor - BiometricUpdate
Biometric liveness testing reportedly is taking a big step forward in a Qualcomm accelerator program with a new algorithm that can spot genuine skin.
Army Modernizes 20-Year-Old Biometrics Database for Troops Patrolling Foreign Checkpoints - BiometricUpdate
The U.S. Army has developed an update to an important 20-year-old biometric data store, known as the BAT-A database and used by soldiers patrolling key overseas checkpoints.
Travelers Passing Through the Progreso Port of Entry on Foot will See a New Crossing Protocol - NextGov
Customs and Border Protection is deploying its facial recognition program at land border crossings at a fifth location ahead of a broader expansion planned for this spring.
