A new bill could change how the US builds energy infrastructure 

A sweeping bit of legislation designed to cut red tape could speed up the buildout of energy infrastructure in the US. With the dust barely settled on this week’s momentous midterms, the Senate is set to vote on the Bipartisan American Affordability and Jobs Act (BAAJA) on November 9. It’s a plan that could finally

What’s next for US energy policy after the midterm elections?

I’ve been locked in to my various screens since results from midterm elections started to roll in last night. And it didn’t take long to see the beginning of the blue wave: Democrats took control of both the US House of Representatives and the Senate, a dramatic swing from Donald Trump’s victory two years ago.

Our climate models have a big, dangerous blind spot

Climate change itself is increasingly fueling climate change. Rising concentrations of greenhouse gases are driving up global temperatures, setting off dangerous feedback loops that we have not fully accounted for in our climate models—or our emissions-reduction goals. Scientists have long warned that warming would propel further warming in various ways, but a growing number of

How solid-state transformers could help power the AI boom

Transformers are a crucial but nearly invisible part of our grid. The devices help efficiently move power across long distances, but they’re complicated and in short supply. And given that their basic design hasn’t changed much for about a century, they could use an upgrade.  As the world races to meet rising electricity demand from

Cleaning up PFAS

Scrubbing Earth of per- and polyfluoroalkyl substances—a.k.a. PFAS or forever chemicals—could eliminate a list of woes for people and planet. Used for decades in everything from nonstick pans to firefighting foams, PFAS have been linked to increased risks of fertility challenges, developmental delays, cancer, and reduced immune response. They are known for a strong bond

These startups hope “blended” food will cut our appetite for red meat 

In the fall of 2025, Jeff Dodge set up a six-foot folding table in the cafeteria of Cane Bay High School in Summerville, South Carolina, to conduct a taste test. When the first rush of about 150 hungry students hit, he was waiting with slow cookers filled with steaming marinara sauce and meatballs.  Kids love

Inside the quest to combat Arctic fires and save the planet’s frozen carbon

In the middle of an especially warm July in 2021, a wildfire ignited in a thick forest of black spruce and peeling paper birch trees on the northern campus of the University of Alaska, Fairbanks.  The blaze, possibly sparked by lightning, burned across the dry carpet of feather mosses and lichen before climbing into the
