The Department of Homeland Security Science and Technology (S&T) Directorate’s Chemical Security Analysis Center (CSAC) is developing a modeling tool that estimates the hazard and related human health consequences from thousands of plausible threat scenarios.

The tool is called the Homeland Explosive Consequence and Threat (HExCAT), and it helps public officials to plan for attacks at special events, such as parades, elections, sporting events and inaugurations. After validation and further development, it will be integrated into national- and regional-level risk analysis.

Lead researcher Dave Soscia said the “brain-on-a-chip” device, designed and fabricated at Lawrence Livermore National Laboratory, was designed to be easily reproducible. The lab has applied for a patent on the device and is looking to engage with potential collaborators to further develop it. Photo by Julie Russell/LLNL

Engineers and biologists at Lawrence Livermore National Laboratory (LLNL) have developed a 3D “brain-on-a-chip” device capable of recording the neural activity of living brain cell cultures. This is a huge advancement in the realistic modeling of the human brain outside of the body.

More than 60 aircraft and 300 personnel from the U.S. Air Force, Navy, Army and Marine Corps participated in 18th Wing’s first WestPac Rumrunner exercise January 10. In addition to air tactics and joint interoperability, Airmen were tasked with ensuring continuous airpower by using tactics derived from Pacific Air Force’s agile combat employment concept of operations, or ACE.

The Department of Homeland Security is reaching out to the private sector for ideas about advanced cloud-based biometric technology for immigration and border security.

The Department of Homeland Security, or DHS, has made a steady march toward the use of digital biometric data for identity management. After the attacks of 9/11, Congress mandated that DHS identify foreign airline travelers coming into the United States through digital fingerprints, and after that, required a biometric identification program for foreign nationals leaving the country. Since then, the department has added biometric identity management for U.S. citizens.

The DragonflEye, a cyborg insect intended for a variety of missions, recently completed its first test flight.

The DragonflEye, a cyborg insect intended for a variety of missions, including intelligence, surveillance and reconnaissance, has liftoff.

The system was created by researchers at Charles Stark Draper Laboratories Inc. and the Howard Hughes Medical Institute’s Janelia Research Campus. The dragonfly wears a tiny backpack fitted with electronics, sensors and a solar cell. A light source charges the solar cell, which powers the backpack.

The DragonflEye recently completed its first test flight for data gathering purposes.
