Latest Sales Data Reveal Clear Winners And Losers in a Messy EV Market

The second quarter of 2025 painted a chaotic picture of the electric vehicle market in the United States. While General Motors enjoyed a breakout quarter, most other automakers, especially Tesla and Ford, stumbled hard. EV sales are now a mix of breakthroughs and breakdowns. And all of this is happening under a White House that has turned decisively against green subsidies. GM Breaks Away From the Pack Despite a political environment hostile to clean energy, GM managed to deliver a stunning 1

The Great American EV Fire Sale Is About to Begin

If you are thinking about buying an electric vehicle, the clock is now ticking. President Donald Trump’s “One Big Beautiful Bill” has officially passed Congress, and with it, a countdown that will kill the popular $7,500 federal tax credit for new electric vehicles. You now have less than three months to act. The tax credit officially expires on September 30, 2025. Initially, there were rumors the EV credits would last 180 days from when the bill was signed, a six-month grace period. This law

Gaspype provides two main classes: fluid and elements . A fluid object can have multiple compositions. A multidimensional fluid object can be created for example by multiplication with a numpy array: In some cases not the molecular but the atomic composition is of interest. The elements class can be used for atom based balances and works similar: el = gp . elements ({ 'N' : 1 , 'Cl' : 2 }) el . get_mass () np . float64 ( 0.08490700000000001 ) A elements object can be as well instantiated fr

Slate Auto drops ‘under $20,000’ pricing after Trump administration ends federal EV tax credit

Slate Auto, the electric vehicle startup backed by Jeff Bezos, has stopped promoting that its upcoming pickup truck will start “under $20,000” following passage of President Trump’s tax cut bill. The bill, which is expected to be signed into law by Trump on July 4, will cause the federal EV tax credit to end in September — a $7,500 incentive that Slate had counted on to help its all-electric pickup clear that mark. When Slate came out of stealth mode in April, the startup heavily promoted that

Physicists start to pin down how stars forge heavy atoms

The Facility for Rare Isotope Beams (FRIB) may not glitter quite like the night sky, plunked as it is between Michigan State University’s chemistry department and the performing arts center. Inside, though, the lab is teeming with substances that are otherwise found only in stars. Here, atomic nuclei accelerate to half the speed of light, smash into a target and shatter into smithereens. The collisions create some of the same rare, unstable isotopes that arise inside stars and which, through a

Nano-engineered thermoelectrics enable scalable, compressor-free cooling

Researchers at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, have developed a new, easily manufacturable solid-state thermoelectric refrigeration technology with nano-engineered materials that is twice as efficient as devices made with commercially available bulk thermoelectric materials. As global demand grows for more energy-efficient, reliable and compact cooling solutions, this advancement offers a scalable alternative to traditional compressor-based refrigeration.

I scanned all of GitHub's "oops commits" for leaked secrets

TL;DR GitHub Archive logs every public commit, even the ones developers try to delete. Force pushes often cover up mistakes like leaked credentials by rewriting Git history. GitHub keeps these dangling commits, from what we can tell, forever. In the archive, they show up as “zero-commit” PushEvents . I scanned every force push event since 2020 and uncovered secrets worth $25k in bug bounties. Together with Truffle Security, we're open sourcing a new tool to scan your own GitHub organization for

That XOR Trick (2020)

There are a whole bunch of popular interview questions that can be solved in one of two ways: Either using common data structures and algorithms in a sensible manner, or by using some properties of XOR in a seemingly hard to understand way. While it seems unreasonable to expect the XOR solutions in interviews, it is quite fun to figure out how they work. As it turns out, they are all based on the same fundamental trick, which we will derive in a bottom-up way in this post. Afterwards we will lo

How to turn off ACR on your TV (and why it greatly enhances your viewing experience)

Kerry Wan/ZDNET Did you know that whenever you turn on your smart TV, you invite an unseen guest to watch it with you? These days, most popular TV models utilize automatic content recognition (ACR), a form of ad surveillance technology that gathers information about everything you watch and transmits it to a centralized database. Manufacturers then use your data to identify your viewing preferences, enabling them to deliver highly targeted ads. Also: Your TV's USB port is seriously underutili

Affluent Travelers Are Ditching Business Class for Business Jets

We’re cruising 35,000 feet over the French Riviera, the plane’s wing cutting through billows of white. Below us, the sea is sparkling, and I spot a cluster of yachts anchored along the coastline. A ray of light hits my glass of Champagne and turns it to liquid gold. I take another sip. So this is what it feels like to be on cloud nine. I’m flying from London to St. Tropez with the private aviation company Wheels Up, and for the first time in my life, I don’t want a flight to end. Once you’ve go

Xbox Elite Wireless Controller 2 Is Overkill for Most People, but Still Delivers an Epic Gaming Experience

The Xbox Elite Wireless Controller Series 2 (or Elite 2 for short) has arguably been the industry gold standard for a pro-level game controller for the past decade. Over the years dozens of competitors have cropped up, hoping to give Microsoft a run for its money. While the Elite 2 still isn't perfect, it still sets the bar high. What I like about the Xbox Elite Wireless Controller Series 2 One of the best things the Elite 2 has going for it is the layout -- it's almost identical to the standa

Google’s data center energy use doubled in 4 years

Xiaomi’s YU7 Is an SUV-Sized Middle Finger to Tesla’s Model Y

Another week, another Chinese electric car poised to deliver an extinction event to Western automakers. This time it’s Xiaomi, a Beijing-based tech firm best known for smartphones and the company behind the Porsche Taycan–baiting SU7, which in late-2024 was so popular that Xiaomi increased its sales forecast three times in a matter of months. Now Xiaomi is back, and this time it has an electric SUV up its sleeve. Resembling the love child of a Ferrari Purosangue and an Aston Martin DBX707 desc
