Modeling Geothermal Systems’ Viability
Geothermal power has a lot of promise as a renewable energy source that is not dependent on the sun shining or the wind blowing, but it has some obstacles to wide adoption. One challenge is that a limited number of locations in the U.S. naturally have the right conditions: hot rock relatively close to the surface and with plentiful groundwater to heat up. Web tool looks belowground for an economically viable renewable energy source.

Huawei’s New Mate 60 Phones Are a Lesson in Unintended Consequences
In October 2022, the Commerce Department introduced a set of export-control measures designed to prevent the use of American chip technology for Chinese military purposes. Rules were also imposed that aimed to restrict China’s semiconductor production to older 14-nm technology. These controls have had varying degrees of success, but the 14-nm restriction is one of the more overt failures, as the 7-nm chips in the new Huawei’s Mate 60 phones shows.

How a Small Caribbean Island Is Trying to Become Hurricane-Proof
Climate change is increasing the frequency and intensity of extreme weather events in the Caribbean and for small islands such as Dominica (not to be confused with the much larger Dominican Republic) it is an existential threat. Unlike larger islands like Cuba or Jamaica, a single storm hitting Dominica can damage the entire country – and the topography and small size of the island imposes hard limits on its ability to adapt.

Non-powered Dams Offer Opportunity for Clean Energy
The era of building big dams may be over in the United States, but hydroelectricity still has a significant and untapped role to play in the nation’s energy future. Trouble is, 97 percent of U.S. dams don’t make electricity. A new tool could help tap that resource.

Reforms Needed to Expand Prescribed Burns
Prescribed fire, which mimics natural fire regimes, can help improve forest health and reduce the likelihood of catastrophic wildfire. But this management tool is underused in the fire-prone U.S. West and Baja California, Mexico, due to several barriers. Study highlights four strategies to overcome barriers to prescribed fire in the West.

Revolutionizing Resource Renewal: Scaling Up Sustainable Recycling for Critical Materials
Permanent magnets, which retain magnetic properties even in the absence of an inducing field or current, are used extensively in clean energy and defense applications. Rare earths are challenging to access because they are scattered across Earth’s crust, yet they are key components in many modern technologies. Recycled rare earths can be used to make new permanent magnets, accelerate chemical reactions and improve the properties of metals when included as alloy components.
Saving Seconds, Saving Lives: NIST-Funded Challenge Crowns Winners in 3D Tracking Technology
NIST has awarded $1.9 million to six teams for innovative 3D tracking solutions in the final phase of a competition. The winning designs combine localization and biometric monitoring, using sensors affixed to first responders’ equipment. This competition is part of an $8 million NIST-funded initiative to address first responders’ need for improved tracking in emergency settings where GPS falls short.
Number of People Affected by Tropical Cyclones Has Increased Sharply Since 2002
The number of people affected by tropical cyclones has nearly doubled from 2002 to 2019, reaching nearly 800 million people in 2019, according to a new study. More people are affected by tropical cyclones in Asia than any other region, but every affected world region saw an increase in the number of people exposed to tropical cyclones, which are expected to become more intense and possibly more frequent as the climate warms.
