Is anything ever normal in the AI industry?

A doozy of a scoop by the newsletter Nongaap Investing and extensively followed up by Business Insider certainly makes us wonder. The gist is that for a period of time in 2023, the person in charge of OpenAI’s $175 million startup fund appears to have been completely fake — and OpenAI says the documents filed with the California Secretary of State to put the fake person in charge were “completely fabricated.”

Head spinning yet? Us too. OpenAI is almost certainly the hottest startup on the planet right now, and it sounds like someone pulled an extrardinary fast one on it, with unclear goals. And lest you think this is some unimportant position, the person now running the fund is none other than OpenAI’s mercurial CEO, Sam Altman.

Medical implants such as pacemakers and gastric stimulators have improved our lives, but the batteries in these devices eventually run out and require surgery to replace them.

It raises a futuristic question: what if there was a way to avoid cutting a patient’s body open to replace a battery?

A team of Chinese scientists have come up with a possible method to pull that off by developing an implantable battery that uses oxygen already inside the human body to continuously power itself up.

In an interview, University of Michigan civil engineer Sherif El-Tawil explained how often ships collide with bridges, what can be done to protect bridges from collisions, and how a similar disaster in Florida in 1980 – just three years after the Key bridge opened – changed the way bridges are built.

This is not the first time a ship has taken out a bridge. What’s the history of ship-bridge collisions?

This is an extremely rare event. To my knowledge, there are about 40 or so recorded events in the past 65 years that involved similar type of damage to a bridge caused by a ship. So they seem to occur on average about once every one and a half to two years around the world. When you consider that there are millions of bridges around the world – and most of them cross waterways – you can imagine how rare this is.

🔗 Top quark and top antiquark entanglement 🔗

The CMS experiment has just reported the observation and confirms the existence of #entanglement between the top #quark and its #Antiparticle beyond reasonable doubt.

The CMS experiment has just reported the observation of quantum entanglement between a top quark and a top antiquark, simultaneously produced at the LHC.

In quantum mechanics, a system is said to be entangled if its quantum state cannot be described as a simple superposition of the states of its constituents. If two particles are entangled, we cannot describe one of them independently of the other, even if the particles are separated by a very large distance. When we measure the quantum state of one of the two particles, we instantly know the state of the other. The information is not transmitted via any physical channel; it is encoded in the correlated two-particle system.

This just in: the James Webb Space Telescope (JWST) is a Tumblr girl, actually.

Since its launch in 2022, the JWST has dazzled the masses with spectacular photos of interstellar sights like the pillars of creation, exploding stars, and — checks notes — squirting moons.

While the public sees those images are seen in striking color, though, that’s not actually how the JWST captures them. As Space.com reports, images snapped by the advanced telescope first arrive to researchers in black and white, and are then colored back on Earth by scientists who use data to make a well-educated guess as to what the cosmic bodies in the pictures might look like in the spectrum of visible light.
