Tornadoes Are Deadly. These New Building Codes Will Save Lives.
Because of its unique geography, the United States has more tornadoes, and more intense tornadoes, than any other country. Tornadoes are deadly, but until recently there were no building codes designed to protect communities from tornadoes. Tornado winds push and pull on buildings in unique ways that require special safety designs. NIST research led to the first building code provision for tornado resilience.

Disaster Recovery: What Community-Driven Relocation Could Look Like
Over the past forty years, the Gulf Region has experienced devastating hurricanes and flooding, costing 232 billion dollars. The gut reaction after any disaster is to rebuild and protect-in-place, but sometimes communities have to consider relocation — but the conversations around rebuilding versus relocation continue to be challenging for policymakers and the communities impacted by disasters.

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.

Silicon Valley Steps Up Screening of Chinese Employees to Counter Espionage
Leading U.S. technology companies reportedly have increased security screening of employees and job applicants, which experts say is necessary to counter the cyber espionage threat from China. Applicantswith family or other ties to China are thought to be particularly vulnerable to pressure from the Beijing government.

To Guard Against Cyberattacks in Space, Researchers Ask ‘What If?’
If space systems such as GPS were hacked and knocked offline, much of the world would instantly be returned to the communications and navigation technologies of the 1950s. Yet space cybersecurity is largely invisible to the public at a time of heightened geopolitical tensions.

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.

To Make Children Better Fact-Checkers, Expose Them to More Misinformation — with Oversight
“We need to give children experience flexing these skepticism muscles and using these critical thinking skills within this online context,” a psychology researcher said.
Social Media Platforms Aren’t Doing Enough to Stop Harmful AI Bots, Research Finds
While artificial intelligence (AI) bots can serve a legitimate purpose on social media — such as marketing or customer service — some are designed to manipulate public discussion, incite hate speech, spread misinformation or enact fraud and scams.
World War I Was the Crucible of Air Power. Ukraine Looks the Same for Drones
We seem to be seeing a new kind of air battle—lower, slower at close quarters and in a physical environment where fighter aircraft cannot intervene affordably or effectively. Could it be that Ukraine is to small unmanned systems what World War I was to aircraft?
Accelerating Clean Energy Geothermal Development on Public Lands
Geothermal energy is one of our greatest untapped clean energy resources on public lands. Replenished by heat sources deep in the Earth, geothermal energy generates electricity with minimal carbon emissions. Interior Department announces new leases and pioneering project approval, and proposes simplified permitting.
Major Lithium Mine Approved in Nevada, Supporting a Domestic Supply of Critical Minerals
Critical minerals are essential building blocks of the modern economy and America’s energy security, from clean energy technologies – like electric vehicle and grid storage batteries and wind turbines – to semiconductors to advanced defense systems and consumer electronics.
Revising the Cost of Climate Change
Climate scientists have warned of calamitous consequences if global temperatures continue their rise. But macroeconomists have largely told a less alarming story, predicting modest reductions in productivity and spending as the world warms. Until now. New study of economic toll yields projections ‘six times larger than previous estimates’.
