Rare Earth Metals at the Heart of China’s Rivalry with U.S., Europe
What if China were to cut off the United States and Europe from access to Rare Earth Elements (REEs), 17 minerals with unique characteristics which are essential to electric vehicles, wind turbines, drones, batteries, sophisticated military gear, and much more? This is a time of growing geopolitical friction among these three, and the United States and Europe want to change the current dependence on China, where, today, these minerals are largely extracted and refined.

The Geopolitics of Rare Earth Elements
The Covid-19 pandemic has exposed fragility in the global supply chains for not only pharmaceuticals and crucial medical supplies but also some critical minerals. Chief among them are rare Earth elements (REEs), which are necessary for clean energy equipment, advanced military gear, and consumer goods. About 80 percent of the world’s REEs are produced and refined in China.

Use of Radioactive Materials in Commercial Applications Has Increased
The use of high-risk radioactive materials in medical, research, and commercial applications has increased by about 30 percent in the U.S. in the last 12 years, and the government should improve security, tracking, and accountability to reduce health and security risks — while also supporting the development of nonradioactive alternatives to replace them — says a new report.

Cyber Regulation Could Be Coming Following Spate of Hacks, Ransomware Attacks
The United States may soon look to regulate private companies, mandating higher standards for cybersecurity following a series of damaging hacks and ransomware attacks against key firms and critical infrastructure. Cybersecurity experts say that malign actors are currently operating with impunity and that too many private sector organizations have, so far, failed to take the necessary precautions. “Enlightened self-interest, that’s apparently not working,” Chris Inglis, tapped to be the country’s first national cyber director, told members of the Senate Homeland Security and Governmental Affairs Committee. “Market forces, that’s apparently not working.”

Difficult Tradeoffs: Climate Change and Dwindling Water Resources
While a drought grips the southwestern United States and water supplies dwindle, decision-makers face increasingly difficult decisions about who, or what, gets water. Researchers have developed a model — the Framework for Assessment of Complex Environmental Tradeoffs (FACET) — designed to navigate and rigorously evaluate competing environmental, economic, and social impacts.

U.S. Attorney General Warns Ransomware “Getting Worse and Worse”
U.S. Attorney General Merrick Garland warned Wednesday that ransom-motivated cyberattacks are “getting worse and worse,” echoing other top Biden administration officials who have sounded the alarm about the problem in recent weeks. “We have to do everything we possibly can here,” Garland told lawmakers. “This is a very, very serious threat.”

Fastly’s Global Internet Meltdown Could Be a Sign of Things to Come
For an hour on the morning of June, dozens of the world’s most-visited websites went offline. Together, these websites handle hundreds of millions of users. This case illustrates the fragility of an internet that’s being routed through fewer and fewer channels. When one of those major channels fails, in what is called a “single point of failure”, the results are dramatic, disruptive and incredibly costly. It’s urgent we address this significant vulnerability if we’re to avoid another global internet meltdown – but this time caused by criminals, not code.

Broad Swath of the Web Knocked Offline by Outage
A broad swath of the World Wide Web has been knocked offline by an outage at edge cloud CDN specialist Fastly. The company runs an “edge cloud,” which is designed to speed up loading times for websites, protect them from denial-of-service attacks, and help them deal with bursts of traffic. The technology requires Fastly to sit between most of its clients and their users. That means that if the service suffers a catastrophic failure, it can prevent those companies from operating on the net at all.

Fastly Global Internet Outage: Why Did So Many Sites Go Down — and What Is a CDN, Anyway?
If you were having difficulty accessing your favorite website on Tuesday time, you’re not alone. A jaw-dropping number of major websites around the globe suddenly became unavailable with no immediately obvious explanation — before reappearing an hour later. To understand why it happened, you need to know what a CDN (content delivery network) is and how crucial they are to the smooth running of the internet.

A 20-Foot Sea Wall? Miami Faces the Hard Choices of Climate Change.
In Miami, the U.S. metropolitan area that is perhaps most exposed to sea-level rise, the problem is not climate change denialism. Patricia Mazzei writes that “the trouble is that the magnitude of the interconnected obstacles the region faces can feel overwhelming, and none of the possible solutions are cheap, easy or pretty.”
