Geoengineering Sounds Like a Quick Climate Fix, but Without More Research and Guardrails, It’s a Costly Gamble − with Potentially Harmful Results
The underlying problem has been known for decades: Fossil-fuel vehicles and power plants, deforestation and unsustainable agricultural practices have been putting more carbon dioxide into the atmosphere than the Earth’s systems can naturally remove, and that’s heating up the planet. Geoengineering, theoretically, aims to restore that balance, either by removing excess carbon dioxide from the atmosphere or reflecting solar energy away from Earth. But changing Earth’s complex and interconnected climate system may have unintended consequences.

Training Students to Succeed in the “Fourth Industrial Revolution”
Transformational changes are already underway in the manufacturing industry as technological advancements, such as artificial intelligence (AI) and smart devices from the “fourth industrial revolution” or Industry 4.0., inspire a digital-first approach to engineering. University of Missouri researchers are using a $1 million grant to support the development of an Industry 4.0 lab, training engineering students for the future of digitization in manufacturing.

Using Hydrogen to Power Disaster Relief
A new vehicle will not only get emergency responders safely to the site of an emergency, but also directly provide power at the scene for up to 72 hours as they assess next steps. And it does all this running on hydrogen—a much more sustainable solution for our environment.

NREL Analysis Reveals Benefits of Hydropower for Grid-Scale Energy Storage
Closed-loop pumped storage hydropower systems rank as having the lowest potential to add to the problem of global warming for energy storage when accounting for the full impacts of materials and construction, according to new analysis. These systems rely on water flowing between two reservoirs to generate and store power.

More U.S. Crops to Require Irrigation
With climate change, irrigating more crops in the United States will be critical to sustaining future yields, as drought conditions are likely to increase due to warmer temperatures and shifting precipitation patterns. Yet less than 20% of the nation’s croplands are equipped for irrigation.

As Competition with China Heats Up, Japan Turns to Africa for Critical Minerals
Demand for such minerals is expected to grow sharply in the coming years. There are, however, supply constraints, as only a limited number of countries produce them. Tokyo has signed agreements with a number of African countries as competition with China for key raw materials and minerals heats up.

We Could Soon Be Getting Energy from Solar Power Harvested in Space
The idea of space-based solar power (SBSP) – using satellites to collect energy from the sun and “beam” it to collection points on Earth – has been around since at least the late 1960s. Despite its huge potential, the concept has not gained sufficient traction due to cost and technological hurdles. space-based solar power is technologically feasible, but to be economically viable, it requires large-scale engineering, and therefore long-term and decisive commitment from governments and space agencies.

Using Quantum Computing to Protect AI from Attack
Despite their incredible successes and increasingly widespread deployment, machine learning-based frameworks such as AI remain highly susceptible to adversarial attacks – that is, malicious tampering with their data causing them to fail in surprising ways. AI can thus be fooled into making mistakes, sometimes risking lives — but quantum computing could provide a strong defense.

Tech Breakthrough Could Increase States’ Use of Geothermal Power
Lawmakers in some states have been laying the groundwork to add geothermal power to the electrical grid and pump underground heat into buildings. Now, a technological breakthrough could dramatically expand those ambitions — and perhaps unleash a new wave of policies to tap into geothermal sources. If the technology’s promise is fulfilled, geothermal could power as much as 20% of the U.S. grid.

What Is Most Likely Going on in Area 51? A National Security Historian Explains Why You Won’t Find Aliens There
One of the reasons people can never be entirely sure about what is going on at Area 51 is that it is a highly classified secret military facility. It was not until 2013 that the U.S. government even acknowledged the existence and name “Area 51.” As a national security historian, I know there’s a long history of secrets at Area 51. I also know that none of those secrets have anything to do with space aliens.

Natural or Not? Identifying Genetically Engineered Organisms
Ever since gene editing became feasible, researchers and health officials have sought tools that can quickly and reliably distinguish genetically modified organisms from those that are naturally occurring. Following the emergence of SARS-CoV-2, the world at large became aware of this need. Now, such tools are being built. The development of new tools to detect modified bacteria, viruses, and cells has bolstered national security against biological threats.
