Can Europe Compete with China's Belt and Road Initiative?
The European Union this week launched a $340 billion “Global Gateway” fund to boost global infrastructure, which analysts say is aimed at rivaling China’s Belt and Road Initiative. But can the EU’s project compete with Beijing’s billions?

Balance of Power—Building a Resilient Electric Grid
Events such as blackouts and outages are increasing in frequency as the nation’s infrastructure ages and climate change leads to extreme weather events. Hotter, wetter summers and harsher winters require more reliance on heating and cooling utilities, placing higher stress on the nation’s electric grid. Newtechnology can ‘help keep the lights on’ during emergencies.

Microgrids May Hold the Key to Grid Resilience
The aging energy grid is being pushed to the breaking point. Power outages from extreme weather alone cost anywhere from $2 billion to $77 billion per year. And some isolated communities still rely on diesel generators for electricity, since powerlines don’t reach them. Grid expansion isn’t an option—in most cases, the economics don’t make sense. When the main grid falls short, the right mix of renewables offers local, low-carbon power.

Earthquakes and Tsunamis in Europe?
Earthquakes and tsunamis do not only threaten distant coasts, but also ports, cities and coasts in European waters. Researchers, provides for the first time comprehensive information on the marine geological hazards that can affect countries across Europe. The manifold risks should be considered more strongly in political and economic decisions.

New Generation of Grid Emergency Control Technology
Grid operators face big challenges and big opportunities when it comes to managing through emergency conditions that disrupt power service. The increasing number of power outages in the United States cost an estimated $30-50 billion and affect millions of customers each year. A real-time adaptive system can safeguard the grid against costly disruptions.

Stacked Deep Learning: Deeper Defense against Cyberattacks
Internet-based industrial control systems are widely used to monitor and operate factories and critical infrastructure. Moving these systems online has made them cheaper and easier to access, but it has also made them more vulnerable to attack. Stacked deep learning offers a better way to detect hacking into industrial control systems.

Machine Learning Helps Measure Building Earthquake Damage
One obstacle which often prevent an effective response to earthquakes is that the buildings from which such a response is managed and response equipment stored, are themselves damaged. Researchers have developed a method to quickly assess damage to such buildings immediately after an earthquake to determine whether the buildings can be continued to be used.

Big Batteries on Wheels: Zero-Emissions Rail While Securing the Grid
Trains have been on the sidelines of electrification efforts for a long time in the U.S. because they account for only 2 percent of transportation sector emissions, but diesel freight trains emit 35 million metric tons of carbon dioxide annually and produce air pollution that leads to $6.5 billion in health costs, resulting in an estimated 1,000 premature deaths each year. Researchers show how battery-electric trains can deliver environmental benefits, cost-savings, and resilience to the U.S.

How Climate Change Will Impact National Security
The recent U.S. National Intelligence Estimate (NIE) lays out the likely security implications over the next two decades of the mounting climate crisis. Calder Walton, the research director at Harvard’s Belfer Center, says: “Let’s start with the basics: that climate change does pose a threat to U.S. national security. The National Intelligence Estimate is a joint assessment produced by the entire U.S. intelligence community, 18 agencies. That’s significant. There are no naysayers; there’s no doubt. So that’s a breakthrough. In this extraordinarily polarized and politicized environment, that is a big milestone itself.”

First Planetary Defense Test
An asteroid slammed into Earth 63 billion years ago, igniting vast fires which threw smoke and soot into the atmosphere, plunging the planet into a prolonged winter, killing many plants on which herbivores depended. The extinction of the dinosaurs was only one consequence of that event. NASA wants to make sure there is no repetition of such a calamity: The agency is planning the first-ever planetary defense test, which deliberately collides a spacecraft into an asteroid called Dimorphos. The aim is to try and deflect the asteroid away from its Earth-bound trajectory.
