THE TOP FIVE
1. The EPA is shutting down its scientific research arm

The Environmental Protection Agency announced plans on Friday afternoon to shut down its research arm and fire hundreds of biologists, chemists, toxicologists, and other scientists whose work helps determine safe pollution levels for regulations. The announcement comes after months of denials from EPA administrator Lee Zeldin that he planned to close the division in question, the Office of Research and Development, which studies the threat from climate change, toxic chemicals, and air and water pollution on human health, and funds university research programs.
The closure comes as part of deep job cuts at the agency. In a statement on Friday, Zeldin said the more than 500 layoffs — which, combined with voluntary buyouts, will slash the EPA’s workforce by nearly one-quarter compared to January’s numbers — would save taxpayers nearly $750 million. The nation’s biggest chemical manufacturers’ lobby agreed, arguing to NPR that the cuts would “ensure American taxpayer dollars are being used efficiently and effectively.” But environmentalists warned that the cuts would “not only cripple EPA’s ability to do its own research, but also to apply the research of other scientists.”
2. Trump’s mineral tariffs spur stock surges and ‘anxiety’
Shares in non-Chinese producers of graphite surged on Friday after the Trump administration slapped new anti-dumping duties of 93.5% on imports of the key mineral for batteries, the Financial Times reported. Combined with existing tariffs on Chinese materials, the new trade levies total more than 160%, according to the consultancy Benchmark Minerals. In response, the stock price for Australia-listed Syrah Resources, the world’s largest non-Chinese graphite miner and the developer behind a key Inflation Reduction Act-funded project in Louisiana, shot up 22%. Canada’s Nouveau Monde Graphite spiked 26%. The dual-listed Australian-U.S. producer Novonix surged 15%.
Not all of President Donald Trump’s mineral tariffs are causing excitement for U.S. allies. Earlier this month, the White House announced 50% tariffs on copper to begin in August, but it has yet to clarify whether those tariffs will apply to refined metal, semi-refined products, or copper ore. The uncertainty is causing “anxiety,” Máximo Pacheco, the chairman of Chile’s state-owned copper miner, told the FT. As Heatmap’s Matthew Zeitlin wrote when the tariffs were first announced, they have the potential to “provide renewed impetus to expand copper mining in the United States. But tariffs can happen in a matter of months. A copper mine takes years to open — and that’s if investors decide to put the money toward the project in the first place.”
3. Virginia regulators send mixed signals on Dominion’s fossil fuel expansion
Regulators in Virginia last week ordered electricity and natural gas provider Dominion to lay out a clearer blueprint for meeting the state’s legally-enshrined carbon-free electricity targets. But the State Corporation Commission still accepted the monopoly utility’s plans to build out more fossil fuel generation, Canary Media reported.
The Virginia Clean Economy Act, passed in 2020, requires Dominion to generate 100% of its electricity from carbon-free sources by 2045. The accepted plan runs up to 2039, leaving just six years to sort out the details of decarbonization. The regulators cautioned that “acceptance does not express approval.” While the statement stopped short of calling into question a proposed 944-megawatt gas complex just south of Richmond, Virginia’s capital, the commission said it would debate plans for another roughly 5 gigawatts of gas-burning power plants before approving construction..
4. BP exits the onshore wind business in the U.S.
British energy giant BP is selling off its U.S. onshore wind business as the Trump administration appears ready to smother the industry. On Friday, New York-based developer LS Power said it agreed to buy BP’s share of 10 wind projects totaling 1,700 megawatts of capacity. As part of the deal, LS Power plans to fold the wind projects into its renewable energy subsidiary, Clearlight Energy, increasing its fleet to 4,300 megawatts.
BP’s exit comes as the Trump administration has vowed to crack down on the expansion of wind and solar power in the U.S. Trump has long personally opposed wind energy, dating back to his unsuccessful fight against turbines erected near his golf course in Scotland before entering politics. Last week, Heatmap’s Jael Holzman reported on a memo from the Department of the Interior calling for political reviews of essentially all solar and wind developments in the U.S. This would at minimum stretch out the already challenging development timeline for projects, a problem especially as developers rush to qualify for federal tax credits.
5. Mercedes is pausing U.S. production of its EQ electric vehicles
Mercedes-Benz is pumping the brakes on U.S. production of its EQ line of electric vehicles as the Trump administration winds down federal tax credits to support purchases of battery-powered cars. The German automaker told InsideEVs that, by the start of September, it planned to temporarily pause assembly lines of all variants of its EQE and EQS sedans and SUVs that are either located in the U.S. or producing vehicles bound for the American market. The manufacturer is no longer taking orders from dealers for the cars.
Reviewers had criticized the EQ models for lacking the quality and sophistication of similar gas-powered lines of Mercedes vehicles. Even before Republicans in Congress rolled back the federal government’s landmark $7,500 tax credit for EVs, Mercedes faced trouble finding buyers. Sales of the EQS sedan and EQS SUV were down 52% in the U.S. in 2024 compared to the previous year. China’s biggest electric automakers, meanwhile, are racing to build factories in Brazil, the largest car market in South America.
THE KICKER
Like tiny winged Magellans measuring barely an inch in size, the Bogong moth of Australia regularly travels more than 600 miles using celestial navigation, according to a new study in Nature. “The moths really are using a view of the night sky to guide their movements,” a researcher told Euronews.
