Scientists found a way to explain bird flocks that “defy” Newton’s third law

Birds can see a large portion of the world around them, but when they fly in flocks, they pay attention only to birds beside them or ahead of them. They do not align their movements with birds behind them. That behavior appears to conflict with Newton's third law, the famous action and reaction principle often summarized as "for every action, there is an equal and opposite reaction."

Scientists just found a hidden weakness in forever chemicals

PFAS, widely known as "forever chemicals," are among the most stubborn pollutants scientists face today. Because these compounds are extraordinarily stable, they can remain in water supplies, ecosystems, and even the human body for decades. Their persistence has made PFAS contamination a growing environmental and public health concern around the world.

Alien messages may have reached Earth without us realizing it

We Drive (What Could Be) the Reborn Toyota MR2

It has been said that test mules are bugs. Shod with GPS antenna, they often crawl through development resembling stag beetles instead of something any of us would drive. If we're ever fortunate enough to see them, it's usually by mistake. Or via the telephoto lens of some fancy helicopter-having spy photographer.

Five Alive! We Drive an Early Prototype of the Fifth-Generation 2027 BMW X5

When discussing the greatest BMWs of all time, the conversation often fixates on an era of Bimmers that excelled in rote commutes and spirited drives alike—the ever important ride-handling balance. The cars from that era all carry a common thread: From 1997 to 2012, an engineer named Bernd Limmer was among those who signed off on the chassis of the E46 M3, E39 M5, and E9X M3, among many others. Limmer is also the principal engineer of the upcoming fifth-generation 2027 X5 (chassis code G65), and his tuning sense might be the special ingredient this new BMW needs to really cook.

ChatGPT Ads Manager Is Now Open to Everyone: Here's How to React | Neil Patel

Key Takeaways

• ChatGPT surpassed $100 million in annualized ad revenue in its first six weeks, generated from less than 20 percent of eligible users seeing ads daily.
• Around 85 percent of free and Go tier users are eligible to see ads, meaning current revenue represents a small fraction of eventual ad capacity.
• Self-serve access launched in May 2026, opening the platform beyond the initial group of managed pilot brands via a new OpenAI Ads Manager.
• OpenAI removed the $50,000 minimum spend requirement entirely, opening the door for businesses of any size.
• ChatGPT now reaches 800 million weekly active users, processing 2.5 billion prompts daily.
• First-mover advantage is real, and it will not last long once self-serve competition normalizes pricing.

For the past several months, advertising on ChatGPT meant getting an invitation. A small group of brands had access. Everyone else waited.

Has the answer to life's origins been hiding in our cells all along? | New Scientist

In every cell of your body, there are mysterious speckles. You need a microscope to see them, but if you peer closely, you will see lots of tiny dots: some sitting still, some moving around as if swept along in invisible currents.

Built in the Open: How Pilot Districts Shaped the Reimagined Khan Academy

When Hanover’s Assistant Superintendent Phil Misecko talks about Khan Academy’s pilot in Hanover Community School Corporation, he does not start with the technology. He starts with the students.

“Our high school kids were excited about competing,” he said in a recent webinar. “Teachers were hearing kids tell other kids, ‘Hey, you better pull your weight. I want to win this Gem competition.’ There’s nothing better than positive reinforcement and motivation among kids.”

This strange material can become strong or fall apart in seconds
