And it’s a perfect fit. Enamel is an incredible material. It’s sturdy enough so that humans can chew but flexible enough that it doesn’t crack with every bite. Unfortunately, humans can not regenerate it. Once lost or damaged, it’s gone forever.

OpenAI’s chief scientist has admitted what we all fear — that artificial intelligence may be gaining consciousness.

Genetically modified are words that bother many in Western countries, but they provide for the necessities of life elsewhere.

Fun fact: If you laid the International Space Station out end-to-end on a football field… it would be really tough to play a game. 🙃

The International Space Station is 356 feet (109 meters) long, just about one yard shy of an American football field—including the end zones. Go deep on more space station fun facts this #SBLVI: https://go.nasa.gov/3swABkE

It is interesting that SpaceX has created working EVA suits for use later this year. Also cool that another crewed Starship mission has been planned. Finally note this is yet another mission without professional astronauts. (2 out of the 3 scheduled crewed Starship missions are with nonprofessionals.)

Jared Issacman would serve as the mission commander and will be accompanied by pilot Scott Poteet and SpaceX employees Sarah Gillis and Anna Menon.

Earlier this year, Russia unveiled their forthcoming “stealth fighter,” the single-engine Su-75 Checkmate, with bold claims about its expected performance and capabilities. Now, as the fighter is being displayed on foreign soil for the first time at this week’s Dubai Air Show, formal statements from its manufacturer have called its stealth credentials into question.

As we discussed at the time, Russia has a long and illustrious history of exaggeration when it comes to unveiling new defense technologies, from the Uran-9 infantry robot that garnered global headlines despite secretly not working at all, to the Checkmate’s older sibling, the Su-57, which is considered the least stealth of its fighter generation and currently exists only in token numbers. Even successful designs like the T-14 Armata main battle tank are smothered under a lack of funding, with Russia unable to produce or field them in any reasonable numbers.

And while the Su-75 has yet to even manifest in a flyable way, the firm responsible for developing the aircraft has carefully tip-toed around the topic of stealth throughout multiple stories published by Russia’s state-owned news outlets in recent months. Even the language used by these outlets is more reserved than you’ll often find in the international media. As one glaring example, you’ll find the Su-75 Checkmate referred to as a stealth fighter all throughout American media… but you won’t find Rostec (the firm developing the aircraft) use that term.
