Hundreds of Tech Companies Want to Cash In on Homeland Security Funding. Here's Who They Are and What They're Selling.
Whenever concerns grow about the security along the U.S.-Mexico border and immigration, the U.S. government generate dollars — hundreds of millions of dollars — for tech conglomerates and start-ups. Who are the vendors who supply or market the technology for the U.S. government’s increasingly AI-powered homeland security efforts, including the so-called “virtual wall” of surveillance along the southern border with Mexico?

Businesses Are Harvesting Our Biometric Data. The Public Needs Assurances on Security
Visual data capturing and analysis are particularly critical compared to non-visual data. That’s why its growing use by businesses raises so many concerns about privacy and consent. While the public remains unaware of the extent to which their visual data is being captured and utilized, their information will be vulnerable to misuse or exploitation.

Hardy Transistor Material Could Be Game-Changer for Nuclear Reactor Safety Monitoring
The safety and efficiency of a large, complex nuclear reactor can be enhanced by hardware as simple as a tiny sensor that monitors a cooling system. That’s why researchers are working to make those basic sensors more accurate by pairing them with electronics that can withstand the intense radiation inside a reactor.

‘Gun Control Is Dead and We Killed It’: Unmasking the ‘Lonely Incel’ Who Designed the World’s Most Popular 3D-printed Firearm
The first 3D-printed firearm emerged in May 2013, but Despite the hype, the reality was that the gun was impractical and unreliable. It was not until spring 2020 that the threat of 3D-printed guns grew significantly with the emergence of the FGC-9. The open-source design was accompanied by a meticulous, step-by-step instructional guide akin to an Ikea assembly booklet. The gun’s mysterious designer boasted in one anonymized interview that, by bringing out these designs and sharing them freely: “We f****d gun control for good; Gun control is dead, and we killed it.”

Decline of American Students in China Could Mean Fewer Experts
The number of Americans studying in China has dropped dramatically in recent years from around 11,000 in 2019 to 800 this year, and the slump is so bad that some China scholars worry the United States could lose a generation of “China experts” as a result.

Climate Change Is Increasing Stress on Thousands of Aging Dams Across the U.S.
There are more than 91,000 dams across the U.S., in all 50 states, with diverse designs and purposes. The average dam age is 57 years, and more than 8,000 dams are over 90 years old. The most recent report card of the American Society of Civil Engineers estimates that 70% of U.S. dams will be more than 50 years old by 2030. Overall, the report gave U.S. dams a “D” grade and estimates that more than 2,300 are high hazard dams which could cause loss of life or serious property damage if they fail.
