GPS Jamming? No Problem, LEO Satellites Hold the Key to Resilient, Interference-Free Navigation
Increasingly occurring GPS jamming disrupts the daily civilian activities, posing major navigational challenges. A new method using Low Earth Orbit (LEO) satellites and massive Multiple Input Multiple Output (MIMO) antennas addresses these location vulnerability issues, presenting means for precise navigation even where traditional global navigation satellite systems (GNSS) fail.

The U.S. Is Finally Curbing Floodplain Development, New Research Shows
Over the past century, the United States has built millions of homes along coastlines and rivers, developing on land that is all but destined to flood. At the same time that the warming of the planet has raised sea levels and increased rainfall, annual flood damages have surged in recent decades in large part because more homes are in flood-prone areas now than ever before.

Pagers and Walkie-talkies Over Cellphones – a Security Expert Explains Why Hezbollah Went Low-Tech for Communications
In general, I believe the adversary in an asymmetric conflict using low-tech techniques, tactics and technology will almost always be able to operate successfully against a more powerful and well-funded opponent. But from a cybersecurity perspective, Israel’s attack on Hezbollah’s pagers shows that any device in your life can be tampered with by an adversary at points along the supply chain – long before you even receive it.

Why Experts Are Calling for a New Strategy to Improve U.S. Access to Semiconductors ― The Technology that Underpins Artificial Intelligence
While the U.S. first developed semiconductors and led globally in semiconductor development and manufacturing in the last century, today it produces just 12% of all semiconductors. A new report from the National Academies recommends actions for the U.S. Department of Defense ― coordinating with the commercial sector, universities, and other parts of government ― to secure its access to this critical technology.

Dams Built to Prevent Coastal Flooding Can Worsen It
The common practice of building dams to prevent flooding can actually contribute to more intense coastal flood events, according to a new study. Those massive infrastructure projects are surging in popularity globally, in part to help offset intensifying storms, salt intrusion and sea-level rise fueled by climate change.

The Gulf Coast Is Sinking, Making Hurricanes Like Francine Even More Dangerous
Hurricane Francine hits low-lying Louisiana. Subsidence could make the storm surge worse: Because so much of southern Louisiana sits at or below sea level, the surge could race inland unimpeded.

Factories First: Winning the Drone War Before It Starts
Wars are won by factories before they are won on the battlefield,Martin C. Feldmann writes, noting that the United States lacks the manufacturing depth for the coming drone age. Rectifying this situation “will take far more than procurement tweaks,” Feldmann writes. “It demands a national-level, wartime-scale industrial mobilization.”
