Gas Sensor Monitors Pollution from Power Plants and Roads 

A research team from Adelphi University in New developed a new device that can detect ultra-low concentrations of gases like nitrogen dioxide accurately and nearly instantaneously. The device works even when experiencing small vibrations, which is important if the instrument is deployed in the field.

Wristband Sensor Predicts and Prevents Asthma Attacks

Researchers have developed an integrated, wearable system that monitors a user’s environment, heart rate, and other physical attributes with the goal of predicting and preventing asthma attacks. The system, called the Health and Environmental Tracker (HET), is composed of a suite of new sensor devices incorporated into a wristband and a patch that adheres to the chest.

Researchers Improve Decontamination Criteria for Combat-Vehicle Coatings

When it comes to protecting warfighters from exposure to chemical agents that have contaminated combat vehicles, determining how much agent gets absorbed into the material matters. That's what researchers at the U.S. Army Edgewood Chemical Biological Center (ECBC) discovered and helped the Army fix.

3D Printer Produces Cartilage from Strands of Bioink

Strands of cow cartilage substitute for ink in a 3D bioprinting process that may one day create cartilage patches for worn out joints. A cartilage strand substitutes for ink in a 3D printing process. Using a specially designed prototype nozzle that can hold and feed the cartilage strand, the 3D printer lays down rows of cartilage strands in any pattern the researchers choose.
