• Creating a Tsunami Early Warning System Using Artificial Intelligence

    Tsunamis are incredibly destructive waves that can destroy coastal infrastructure and cause loss of life. Early warnings for such natural disasters are difficult because the risk of a tsunami is highly dependent on the features of the underwater earthquake that triggers it.

  • Progress in Alternative Battery Technology

    It is not easy to make batteries cheap, efficient, durable, safe and environmentally friendly at the same time. Researchers have now succeeded in uniting all of these characteristics in zinc metal batteries. Zinc batteries are considered a possible future alternative to the lithium-ion batteries now widely in use. Currently, however, their use often requires toxic salts.

  • AI Can Predict Electricity Grid Loads from Road and Rail Usage Data

    To satisfy demand and manage consumption peaks, electricity suppliers have to be able to predict grid loads. Researchers havedeveloped an artificial intelligence system capable of accurately anticipating grid loads from road and rail traffic data.

  • EV Batteries: Chinese Dominance Raises Thorny Questions

    Chinese firms currently dominate the electric vehicle battery supply chain — from mining and refining through to final assembly. This leaves Western automakers with little option but to rely on Chinese-made batteries.

  • The Potential for Geologic Hydrogen for Next-Generation Energy

    Hydrogen, you may recall from your school days, is a gas. It is considered the cleanest fuel, because burning it only produces heat and pure water. A previously overlooked, potential geologic source of energy could increase the renewability and lower the carbon footprint of the U.S. energy portfolio: natural hydrogen.

  • SUPER Technology Manages Intelligent Building Blocks for a More Reliable Electric Grid

    As the United States transitions to cleaner energy and more U.S. consumers adopt electric vehicles, the grid is facing new power flow demands. Researchers are tackling this challenge by creating a new architecture to modernize the grid from the bottom up, starting with consumers and expanding to the entire power distribution system.

  • Governments Are Using Science Fiction to Predict Potential Threats

    From high-tech fighting machines to supercomputers and killer robots, science fiction has a lot to say about war. You might be surprised to learn that some governments are now turning their attention to these fantastical stories as a way to think about possible futures and try and ward off any potential threats.

  • Making Drones Suitable for Cities

    Unmanned aerial vehicles will make their way into urban skies only if the safety of people below can be ensured.

  • Detecting Manipulations in Microchips

    Attackers have the ability not only to manipulate software, but also to tamper with the hardware. A team from Bochum is devising methods to detect such tampering.

  • Investigators May Be Able to Use Household Dust as a Forensic Tool

    A new study found it is possible to retrieve forensically relevant information from human DNA in household dust. After sampling indoor dust from 13 households, the researchers were able to detect DNA from household residents over 90% of the time, and DNA from non-occupants 50% of the time. The work could be a way to help investigators find leads in difficult cases.

  • New Algorithm Keeps Drones from Colliding in Midair

    Researchers create a trajectory-planning system that enables drones working together in the same airspace to always choose a safe path forward.

  • Kites Aim to Tap Unused High-Altitude Wind Power

    There is a growing interest in harvesting what are known as high-altitude winds. At a height of 200 meters (656 feet) and more, winds tend to blow stronger and more steadily than those closer to the ground. High-altitude winds remain a huge untapped source of renewable energy, but a race to the sky is well underway.

  • Channeling NEXTGEN TV to Help Responders Answer the Call

    A natural disaster strikes, vehicles collide on a snowy highway, a 5-alarm fire blazes through the night. For first responders, every second counts. DHS S&T is collaborating on a new effort to arm agencies with a digital alerting system that taps into NEXTGEN public TV broadcasting technologies to deliver emergency dispatches faster.

  • Preventing Fires and Explosions

    Lines in natural gas grids have to be maintained and serviced regularly. This entails using flares to vent the natural gas. With FlareSimulator, research scientists at the Fraunhofer Institute for Factory Operation and Automation IFF have developed an assistive tool that calculates the correct distance of flares to houses, trees and other nearby objects. This makes it easy to maintain minimum distances and prevent potential hazards and explosions.

  • New Method Helps Locate Deposits of Critical Metals

    The global shift to a carbon-free energy system is set to drive a huge increase in the demand for rare or limited earth minerals. This presents an urgent need to locate new sustainable sources of these elements. New technique could help locate new deposits of critical metals needed to enable the green-energy transition.
