• Apps for Popular Smart Home Devices Contain Security Flaws

    As Internet of Things (IoT) devices such as connected locks, motion sensors, security cameras and smart speakers become increasingly ubiquitous in households across the country, their surging popularity means more people are at risk of cyber intrusions. Researchers have found that the smartphone companion applications of 16 popular smart home devices contain “critical cryptographic flaws” that could allow attackers to intercept and modify their traffic.

  • Why It Matters That North Korea Tested a Hypersonic Missile

    Like most ballistic missiles, hypersonic glide vehicle (HGVs) fly at hypersonic speeds, or faster than five times the speed of sound. But HGVs are in theory more difficult to detect and intercept, since they can fly at relatively low altitudes and be maneuvered in flight.

  • U.S. and EU, Wary of China, Forge Alliance on Technology

    With Beijing on the rise as a tech superpower, Brussels and Washington want to close ranks. But divisions loom over the new “Trade and Technology Council” alliance — and previous efforts have a mixed track record.

  • Powerful Clean Energy Available in Our Oceans

    Marine energy—clean power generated from ocean currents, waves, tides, and water temperature changes—is still young, but it has the potential to deliver clean, renewable electricity to coastal communities where nearly 40 percent of Americans live. Before that can happen, scientists need to pinpoint which oceanic arteries host the most reliable energy.

  • Lowering the High Cost of Desalination

    Removing salt and other impurities from sea-, ground- and wastewater could solve the world’s looming freshwater crisis. A suite of analytical tools makes it easier for innovators to identify promising research directions in making saltwater potable.

  • Harnessing Drones, Geophysics and Artificial Intelligence to Remove Land Mines

    Mines and other unexploded ordinance are a worldwide menace; about 100 million devices are thought to be currently scattered across dozens of countries. Aside from putting both wartime and postwar areas off limits to travel, agriculture or anything else, they caused at least 5,500 recorded casualties in 2019; totals in many previous years have been much higher. Some 80 percent of the victims are civilians, and of those, nearly half are children.

  • Teaching Vehicle Cybersecurity

    University of Detroit Mercy recently received a $1.12-million award from the United States Department of Defense (DoD) to establish the Regional Vehicle Cybersecurity Institute, a regional-based, cybersecurity consortium. “Without an increase to the workforce now, the cybersecurity risk to DoD and commercial ground vehicles will keep falling further behind the increasing threats from actors in multi-domain contested environments,” said one expert.

  • Detecting, Identifying Small Drones in Urban Environment

    DHS has awarded $750K to a Texas company to develop a detection and tracking sensor system that can identify nefarious small unmanned aerial vehicles (UAV) in an urban environment.

  • Redesigning Radiation Monitors at U.S. Ports of Entry

    Every day at ports of entry around the country, hundreds of thousands of vehicles and containers cross into the country. Since 9/11, all incoming vehicles and containers at land crossings, rail crossings, mail facilities, and shipping terminals are scanned by Customs and Border Protection (CBP) officers to detect potential threats, including radiation. The time has come to replace and upgrade the aging radiation detection systems.

  • New Armed Robot to Patrol Battlefield, Border

    An Israeli defense contractor on Monday unveiled a remote-controlled armed robot which can patrol battle zones, borders, track infiltrators, and open fire. The robot can also be programmed to make decisions on its own, without human intervention, about opening fire.

  • Apollo Program-Style Pandemic Preparedness Plan

    Last week, the Biden administration announced a new biosecurity plan which it likened to the Apollo program of the late 1960s. This $65 billion proposal would be one of the largest investments in public health in American history and would “remake the nation’s pandemic preparedness infrastructure in the wake of Covid-19.”

  • Detecting Forged Video Evidence

    Video evidence is commonly used to prove what happened during an event. However, with the emergence and rapid development of CGI (computer-generated images), deep fakes, and video manipulation, there is a pressing need for tools to detect forgeries that would otherwise undermine the value of video evidence.

  • Keeping First Responders Safe by Detecting Cyanide Poisoning after Fires

    When first responders rush to a burning building to subdue the fire and save lives, it is not just the flames that are dangerous and potentially lethal, but also toxic fumes like cyanide that are released when certain materials are incinerated. These fumes, mixed with smoke, are so toxic that even in very low quantities may pose more risk than the fire itself. Chemists at DHS S&T have invented a test to indicate possible toxic cyanide exposure at the fire scene.

  • Future Solutions for Spent Nuclear Fuel

    Nuclear technology has been used in the United States for decades for national defense, research and development, and carbon-free electric power generation. Nuclear power is a key element of the U.S. response to climate change and reducing greenhouse gas emissions. However, nuclear energy, as an essential form of electricity production, generates radioactive waste in the form of spent nuclear fuel. Spent nuclear fuel must be handled, stored, and ultimately disposed of in a manner that won’t harm the environment.

  • DOD Imagery Information Aids Wildland Firefighters

    With continuing significant fire activity in the western United States this year, the Department of Defense (DoD) is delivering requested personnel, equipment, and facilities, to assist our Federal, State, and local partners fighting wildland fires. One of the tools provided by the DoD is the Firefly system pilot program (Firefly), a capability from the National Geospatial-Intelligence Agency (NGA).
