With CEOs from Ford and Stellantis in attendance, President Donald Trump proposed rolling back fleet-wide fuel economy to 34.5 miles per gallon for 2031 model-year cars. The previous fuel economy standard, set under the Biden administration, mandated fuel economy of 50.4 mpg by 2031. The regulation change also reclassifies crossovers as cars instead of light trucks, and it eliminates automakers' ability to trade electric vehicle credits. The National Highway Traffic Safety Administration regulates fuel economy rules under Corporate Average Fuel Economy (CAFE) Standards. Those rules, first enacted by Congress in 1975, dictate how far vehicles must travel on a gallon of fuel. In 2024, automakers had to average 30.1 mpg across their fleets, which they beat, delivering 35.4 mpg, according to CAFE calculations. The White House claims that existing regulations would have caused automotive prices to increase by $1,000 per vehicle. The previous Trump administration made the same argument in 2020, when it last rolled back fuel economy standards....

Transportation Secretary Sean Duffy wants us to return to the golden age of air travel, when nobody got into a punching match for reclining a seat into someone else's lap. He says this golden age starts with us, and he has a whole campaign prepared! I assume it will involve more humane accommodations for travelers'or less harrowing working conditions for the flight attendants charged with both crowd control and safety. Or modernizing air-traffic control to make it safer and more efficient. Now to lower my tray table, take a sip from my tiny plastic cup dangerously overfilled with cranberry juice, and see what he has recommended. There's a video with footage of air travel seemingly from the 1960s' He is in a suit' And he wants us to dress 'with respect,' and 'go back to an era when we didn't wear pajamas to the airport'' Sometimes I wish I did not know the difference between correlation and causation. I think I would be happier. I would certainly have a lot more suggestions for solving problems. And I could tell people, with a straight face, to wear suits to the airport to usher back in a golden age....

The company, founded in 2017 by former Tesla CTO JB Straubel, initially focused on recycling scrap from battery cell production, consumer electronics, and used EV batteries. The company extracts materials like cobalt, nickel, and lithium from those discarded goods and then sells them back to its customers, which include Panasonic. Redwood has since added cathode production. It recently launched a new business that uses those old EV batteries in energy storage products ' a sector that has taken off during the boom of power-hungry AI data centers. As of June, the company had stockpiled more than 1 gigawatt-hour's worth of batteries for this purpose. StrictlyVC concludes its 2025 series with an exclusive event featuring insights from leading VCs and builders such as Pat Gelsinger, Mina Fahmi, and more. Plus, opportunities to forge meaningful connections....

The U.S. military is mighty, formidable, and singular in influence, stationed in at least 128 overseas bases across 51 countries. Concealed beneath the United States' biggest investment is a surprise: The military was responsible for the birth of an industry. Today, that industry is essential for its operations. 'If you think about it, logistics started as a military function,' says Chris Caplice, executive director of the MIT Center for Transportation and Logistics (CTL). 'The idea of getting supplies, ammunition, food, all the material you need to the front line was the core of logistics, and really supply chain came out of that over the last decades or centuries.' For Caplice and the leadership at MIT CTL, a collaboration with the U.S. military seemed inevitable. In 2006, MIT CTL launched the Military Fellows program, wherein three military logistics officers participate in the MIT Supply Chain Management master's program. 'The education goes two ways: One is that these people who have been in the service for more than 20 years step out of their silo and see all the research we're doing that's more focused on the private sector, and is cutting-edge. On the other side, you have students who may have never interacted with the military are able to learn from them,' reflects Caplice....
