The U.S. Army Tried Portable Nuclear Power at Remote Bases 60 Years Ago – It Didn’t Go Well
The U.S. military’s Camp Century was a series of tunnels built into the Greenland ice sheet and used for both military research and scientific projects. The military boasted that the nuclear reactor there, known as the PM-2A, needed just 44 pounds of uranium to replace a million or more gallons of diesel fuel. Heat from the reactor ran lights and equipment and allowed the 200 or so men at the camp as many hot showers as they wanted in that brutally cold environment. The PM-2A was the third child in a family of eight Army reactors, several of them experiments in portable nuclear power.

Report from Europe’s Flood Zone: Researcher Calls Out Early Warning System Gridlock amid Shocking Loss of Life
In my Ph.D. research, I study how we can effectively adapt to the consequences of increasing severe weather events under climate change and what can be done to prepare for them and mitigate their impact. One area I’m interested in is early warning systems, or the lack thereof, during extreme weather events, such as the recent floods in western Europe. While the climate is certainly a complex system that is difficult to predict with any certainty, the unfolding catastrophe is a sad reminder of just how inadequate early warning systems can be.

Can the Destructive Bootleg Fire Teach Us to Prevent Wildfires Before They Start?
More and more, people are moving to less populous, woodland regions of the country, a phenomenon that puts more people in the path of potential wildfires and requires critical utilities such as power and water to be transported long distances from their origins. This creates a system of infrastructure that’s vulnerable to major disruptions—which is exactly what happened in the Bootleg fire.

Climate Change to Bring More Intense Storms Across Europe
Climate change is driving a large increase in intense, slow-moving storms, a new study finds. It is these slow-moving storms that have the potential for very high precipitation accumulations, with devastating impacts, as we saw in Germany and Belgium.

Did the Cybersecurity Workforce Gap Distract Us from the Leak?
There are 500,000 unfilled cybersecurity positions in the United States, and the number is growing. The government and private companies have been investing a lot of money and effort in training and recruiting young cybertalent through college programs, school partnerships, and by adjusting pay and benefit packages, but many have missed a significant leak in cyber workforce funnel: the rapid burnout and churn. In fact, the cyber workforce gap is in experienced roles, not junior levels. To fill the cyber workforce gap, we need to find ways to retain experienced cybersecurity talent.

Developing Cohesive, Domestic Rare Earth Element Technologies
The U.S. has adequate domestic REE resources, but its supply chain is vulnerable due to dependence on foreign entities for separation and purification of these elements. DARPA program aims to fortify supply chain by utilizing bioengineering approaches to facilitate REE separation and purification.

Exploring Rare Earth Elements Opportunities
The purified form of REE is primarily sourced from foreign nations, so the U.S. supply chain of the rare earth elements presents a problem. Justin Wilson, a Cornell chemistry professor, has received a DOE grant to develop more efficient methods of separating rare earth elements that will make their domestic availability economically viable.

Experts Discuss Geothermal Potential
By Graeme Beardsmore and Rachel Webster, University of Melbourne
Geothermal energy harnesses the heat from within Earth—the term comes from the Greek words geo (earth) and therme (heat). It is an energy source that has the potential to power all our energy needs for billions of years.
