The popularity of remote food delivery skyrocketed during the COVID-19 pandemic, and the trend has continued to help businesses thrive years later. Unfortunately, some of the robotic delivery vehicles are taking a beating, with several viral videos showing people kicking the autonomous bots over and even stealing the products inside.

The new study, published in Nature, showed that the unassuming protein is far from a one-trick pony. Rather than a simple protein cog in the body’s wound-healing machine, PF4 also acts as an ambassador between the brain and the immune system. When young, the protein “gatekeeper” tunes down inflammation and helps maintain the brain’s cognitive functions.
Unfortunately, PF4 levels in the body nosedive with age. The drop incites a spark of inflammation in the brain’s “memory center”—the hippocampus—and hampers the neurons’ ability to communicate. Neural networks misfire. As does memory: an aged animal struggles to remember new places or learn new tasks.
It’s not all bad news. In one test, a jab of PF4 partially reset the body’s immune system, lowering levels of proteins that promote inflammation, and boosted cognition in elderly mice.
The chief technology officer of a robotics startup told me earlier this year, “We thought we’d have to do a lot of work to build ‘ChatGPT for robotics.’ Instead, it turns out that, in a lot of cases, ChatGPT is ChatGPT for robotics.”
Until recently, AI models were specialized tools. Using AI in a particular area, like robotics, meant spending time and money creating AI models specifically and only for that area. For example, Google’s AlphaFold, an AI model for predicting protein folding, was trained using protein structure data and is only useful for working with protein structures.
So this founder thought that to benefit from generative AI, the robotics company would need to create its own specialized generative AI models for robotics. Instead, the team discovered that for many cases, they could use off-the-shelf ChatGPT for controlling their robots without the AI having ever been specifically trained for it.

You might be wary – or weary – of headlines that begin with “scientists are trying to build,” because most of them really don’t seem to watch enough science fiction movies.
Additionally, iProov reveals a 295 percent yearly increase in biometric attacks that use novel face swaps. Using this technique, attackers generate synthetic images with AI, either replacing the face of the victim with a video of him to bypass liveness checks or with the face of the attacker itself.
But beyond deep fakes and other more rudimentary presentation attacks where identities are spoofed using masks or other presentation techniques, another type of attack is gaining ground: digital injection.
Salesforce is leading a financing round in Hugging Face, one of the most highly valued startups helping businesses use artificial intelligence, at a valuation north of $4 billion, according to two people with knowledge of the situation. The roughly $200 million funding round more than doubles the share price and private valuation of the New York–based company, one of these people said.
Salesforce is paying a high price for a piece of Hugging Face, which runs a service that helps companies store and use AI software, similar to the way GitHub lets developers store software code. The new funding valued the startup at more than 100 times its annualized revenue, a measure of how much revenue the company would generate over the next 12 months at its current rate, one of the people said.
