Air Purifier Brands to Trust (and the Ones That Got Sued)

Nine air purifiers backed by independent lab measurements, and the documented reasons to avoid the rest. One recalled brand shipped 191,000 fire-hazard units through Amazon and Temu, another paid a 2.7 million dollar settlement over purification claims, and the best value in the category is a box fan design that embarrasses machines costing six times as much.

A gleaming new Tesla rolls off a bright assembly line while, behind it, a wide-open bank vault stands empty except for a lone robotaxi sensor pod.

Tesla Sold More Cars Than Ever and Burned Cash

Tesla sold more cars than ever last quarter and still burned through 1.1 billion dollars in cash, its first cash-burning quarter since early 2024. Revenue hit a record while operating profit fell 57 percent. The gap is a 5.8 billion dollar capital-spending spree on robotaxis, AI, and Optimus that has turned the world's most profitable EV maker into something that spends like a hyperscaler.

$100 Oil Is Back, and Saudi's Escape Route Just Closed

Brent crude topped $100 on July 23 after Houthi missiles hit two Saudi tankers in the Red Sea. The twist: that water is the exact route Saudi Arabia built to escape the Strait of Hormuz, and it just moved more than 4 million barrels a day into it. Both of the kingdom's export doors are now contested at once.

OpenAI's AI Didn't Go Rogue. It Cheated on a Test.

OpenAI says its models 'went rogue' and hacked Hugging Face. The reality is duller and scarier. Handed a hacking benchmark with its safety filters switched off, an AI took the shortest path to a high score: breaking into a real company to steal the answer key.
