Wood Is Making a Comeback in Construction
In the past 150 years, as cities and skyscrapers have boomed, wood has been eclipsed by newer materials such as concrete and steel. Experts say that we shouldn’t accept the dominance of the steel-and-concrete jungle just yet. Thanks to the work of engineers, our oldest building material is experiencing a revival — one that can even withstand earthquakes.

Directed Energy: The Focus on Laser Weapons Intensifies
There a growing interest in directed energy weapons, once considered in the realm of science fiction. How to separate the considerable hype about these futuristic-sounding technologies from their more-nuanced impacts on the real-world battlefields of today and tomorrow?

New Low-Tech Innovation for Emergency Squad Communication
Researchers developed a web-based automated dialing solution enabling civil defense units to communicate with each other during emergencies without Internet service. This low-tech ability is critical for times when connectivity is down; for squads comprised of ultra-Orthodox (haredi) Jews, who often do not have smartphones; and for older first responders who may be less technologically savvy.

Is the Southwest Too Dry for a Mining Boom?
Critical minerals for the clean energy transition are abundant in the Southwest, but the dozens of mines proposed to access them will require vast sums of water, something in short supply in the desert.

Clusters of Atmospheric Rivers Amp Up California Storm Damages
When multiple atmospheric rivers hit California back-to-back, the economic damage from resulting rain and snowfall is three to four times higher than predicted from individual storms, a Stanford study finds. The insight could help water managers and disaster planners better prepare for future impacts of climate change.

A Non-Proliferation Solution: Using Antineutrinos to Surveil Nuclear Reactors
Antineutrinos generated in nuclear fission can be measured to remotely monitor the operation of nuclear reactors and verify that they are not being used to produce nuclear weapons, scientists report. Thanks to a newly developed method, it is now possible to estimate a reactor’s operation status, fuel burnup, and fuel composition based entirely on its antineutrino emissions. This technique could contribute massively to nuclear non-proliferation efforts and, in turn, safer nuclear energy.

The Challenge of Cheap Drones: Finding an Even Cheaper Way to Destroy Them
The sudden proliferation of inexpensive drones in Ukraine is a revolution in warfare. While they vary in size and capability, the economics of defense are particularly stressed by the very cheapest ones, those adapted from civilian models or made with commercially available components.

Creating the Self-Healing Grid of the Future
Self-healing electrical grids: It may sound like a concept from science fiction, with tiny robots or some sentient tech crawling around fixing power lines, but in a reality not far from fiction, a team of researchers is bringing this idea to life. What’s not hard to imagine is the potential value of a self-healing grid, one able to adapt and bounce back to life, ensuring uninterrupted power even when assailed by a hurricane or a group of bad guys.

Investors Are “Flying Blind” to Risk of Climate Lawsuits
Polluting companies could be liable for trillions in damages from climate lawsuits. But few investors and regulators are taking these risks into account when evaluating companies’ climate-related financial risks. Experts call for an overhaul in how climate litigation risks are assessed and provides a new framework for doing so.

A Drone with Ears
When a region is hit by a natural disaster, searching for survivors is complex work as buildings and roads may be damaged. The use of drones equipped with daylight cameras and thermal imaging cameras is therefore becoming increasingly widespread – except that if victims are trapped under rubble, they cannot be seen by these imaging sensors. Equipping drones with acoustic sensors allows rescue teams to identify and locate cries for help, clapping, or knocking signals.

Central Asia Key to Breaking China's Rare Earth Monopoly
U.S. officials hoping to break China’s near monopoly on the production of rare earth elements needed for many cutting-edge technologies should engage the governments of Central Asia to develop high concentrations of REEs found in the region, says a new report.

Autonomous Vehicle Technology Vulnerable to Road Object Spoofing and Vanishing Attacks
Researchers have demonstrated the potentially hazardous vulnerabilities associated with the technology called LiDAR, or Light Detection and Ranging, many autonomous vehicles use to navigate streets, roads and highways. The researchers have shown how to use lasers to fool LiDAR into “seeing” objects that are not present and missing those that are – deficiencies that can cause unwarranted and unsafe braking or collisions.
Tantalizing Method to Study Cyberdeterrence
Tantalus is unlike most war games because it is experimental instead of experiential — the immersive game differs by overlapping scientific rigor and quantitative assessment methods with the experimental sciences, and experimental war gaming provides insightful data for real-world cyberattacks.
Prototype Self-Service Screening System Unveiled
TSA and DHS S&T unveiled a prototype checkpoint technology, the self-service screening system, at Harry Reid International Airport (LAS) in Las Vegas, NV. The aim is to provide a near self-sufficient passenger screening process while enabling passengers to directly receive on-person alarm information and allow for the passenger self-resolution of those alarms.
