• Testing Environments Help Secure Transportation Infrastructure

    “All critical infrastructure sectors—including the energy, manufacturing, and transportation sectors—rely heavily on sophisticated technologies like industrial control systems, cellular networks, and artificial intelligence,” said DHS S&T’s Alex Karr. “These are all accessed, monitored, and controlled via the internet, which, in turn, makes them susceptible to hacking, malware attacks, and other malicious activities.”

  • Majority of California's Coastal Airports Are Vulnerable to Increased Flooding Caused by Climate Change

    Most of California’s population and its largest airports are located along the Pacific coastline, which is increasingly impacted by storm surges, sea level rise, and erosion due to climate change. In the next 30 years, sea level along the coast is expected to rise as much as 8 inches.

  • Railroad Unions and Their Employers at an Impasse: Freight-Halting Strikes Are Rare, and This Would Be the First in 3 Decades

    The prospect of a potentially devastating rail workers strike is looming again. Strikes that obstruct transportation rarely occur in the United States, and the last one involving rail workers happened three decades ago. But when these workers do walk off the job, it can thrash the economy, inconveniencing millions of people and creating a large-scale crisis.

  • Why Do Self-Driving Cars Crash?

    As they traverse the air, land, or sea, encountering one another or other obstacles, these autonomous vehicles will need to talk to each other. Experts say we need to inject cybersecurity at every level of the autonomous vehicle networks of the future.

  • DHS to Stabilize Its Historic Lighthouse on Plum Island

    DHS S&T is leading a project aiming to stabilize the historic Plum Island Light Station. The lighthouse was constructed in 1869 and put into service in 1870. Plum Island, New York, is located approximately 1.5 miles from the eastern end of Long Island’s North Fork. The island is wholly owned by the DHS and primarily serves as a secure location for DHS S&T’s Plum Island Animal Disease Center (PIADC).

  • As Ebola Spreads in Uganda, U.S. Imposes Traveler Screening

    The Biden administration announced last week that all travelers entering the United States from Uganda will be redirected to airports where they can be screened for Ebola virus disease (EVD). Ebola detection is not straightforward, as symptoms can lay dormant for two to 21 days, and during that time, the disease wouldn’t show up on a blood test, let alone a thermometer.

  • The Next Generation of Explosives Trace Detection is Here

    Launched in fiscal year 2020, NextGen Explosives Trace Detection (ETD) expands the scope of aviation checkpoints technology, resulting in the advancement of technologies that can quickly and accurately collect and analyze samples in a variety of ways, including from direct contact with the subject, non-contact sampling via vapors, and even through barriers.

  • Charging Cars at Home at Night Is Not the Way to Go: Study

    The move to electric vehicles will result in large costs for generating, transmitting, and storing more power. Shifting current EV charging from home to work and night to day could cut costs and help the grid, according to a new Stanford study.

  • Not-So-Safe Automated Driving: Safety Risks During Drivers’ Takeover

    In a recent study on automated driving traffic and engineering psychologists analyzed reactions to possible malfunctions of this future human-machine interface. The study shows that people are only partially able to take over the wheel quickly and safely in the event of technical malfunctions.

  • Electric Planes Are Coming: Short-Hop Regional Flights Could Be Running on Batteries in a Few Years

    Electric planes might seem futuristic, but they aren’t that far off, at least for short hops. In the 2030s, experts say, electric aviation could really take off.

  • An AI Pilot May Be Able to Navigate Crowded Airspace

    Researchers believe they have developed the first AI pilot that enables autonomous aircraft to navigate a crowded airspace. The artificial intelligence can safely avoid collisions, predict the intent of other aircraft, track aircraft and coordinate with their actions, and communicate over the radio with pilots and air traffic controllers.

  • Why UK Railways Can’t Deal with Heatwaves – and What Might Help

    Like most construction materials, steel, which rails are made from, expands when air temperature increases. When this movement is restrained by the anchorage, which holds the rail and the sleeper (the rectangular supports for the rails) in place, internal stresses build up, and compression buckles or kinks the rail. Trains cannot travel over rail lines with kinks. In the US, kinks caused by the sun caused over 2,100 train derailments in the past 40 years, equivalent to around 50 derailments per year.

  • D.B. Cooper, the Changing Nature of Hijackings and the Foundation for Today’s Airport Security

    Many Americans may associate airport security with 9/11, but it was a wave of hijackings in the late 1960s and early 1970s that laid the foundation for today’s airport security protocols. Especially, the 24 November 1971 hijacking of a Northwest Orient 727 plane, after take-off from Portland, Oregon, by a man known to the American public as D. B. Cooper, captured the public’s imagination, and drove the U.S. government to establish the first anti-hijacking security protocols.

  • Remote Screening Demonstration at Cape Cod Gateway Airport

    DHS S&T successfully conducted a demonstration of remote screening infrastructure for airport security checkpoints. The Integrated Defense & Security Solutions (IDSS) can send computed tomography (CT) X-ray images of carry-on baggage flagged for threats to remote locations for near real-time analysis.

  • Inside the Government Fiasco That Nearly Closed the U.S. Air System

    The upgrade to 5G was supposed to bring a paradise of speedy wireless. But a chaotic process under the Trump administration, allowed to fester by the Biden administration, turned it into an epic disaster. The problems haven’t been solved.
