Blast-proof CCTV tested by DHS's S&T
CCTVs help the police identify terrorists who perpetrate an attack; trouble is, the blast set by the terrorists may destroy the camera and its video; there are two solutions: the more expensive one is a real-time streaming-video CCTV which sends images back to HQ until the moment the camera is destroyed; the cheaper alternative is an indestructible video CCTV

Bacteria prevents concrete from cracking
Concrete is one of the most commonly used building materials. It is cheap, strong, and easy to work with; there is a catch, though: it cracks easily; Dutch researchers find that mineral grains formed in the cracks of concrete that had been seeded with bacteria would go a long way toward sealing those cracks and making them waterproof

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

DHS: brain music to relax first responders
DHS to use technique which measures a first responder’s brain signatures by using an electroencephalogram, then turn them into synthesized piano music — either a stress-reducing relaxation track, or an alertness-boosting one “for improved concentration and decision-making”

Revolutionizing Resource Renewal: Scaling Up Sustainable Recycling for Critical Materials
Permanent magnets, which retain magnetic properties even in the absence of an inducing field or current, are used extensively in clean energy and defense applications. Rare earths are challenging to access because they are scattered across Earth’s crust, yet they are key components in many modern technologies. Recycled rare earths can be used to make new permanent magnets, accelerate chemical reactions and improve the properties of metals when included as alloy components.
Saving Seconds, Saving Lives: NIST-Funded Challenge Crowns Winners in 3D Tracking Technology
NIST has awarded $1.9 million to six teams for innovative 3D tracking solutions in the final phase of a competition. The winning designs combine localization and biometric monitoring, using sensors affixed to first responders’ equipment. This competition is part of an $8 million NIST-funded initiative to address first responders’ need for improved tracking in emergency settings where GPS falls short.
Unlocking Energy-Efficient Solution to Global Water Crisis
Researchers achieved a major breakthrough in Redox Flow Desalination (RFD), an emerging electrochemical technique that can turn seawater into potable drinking water and also store affordable renewable energy.

For First Responders, Communication with Their Teams is Essential
When a first responder enters a building during an emergency, they count on being able to communicate with their team at all times. Their safety and their ability to carry out the mission relies on knowing they can reach help and support anywhere that they need to go within a structure.
