With the jump, SpaceX is now the world’s second most valuable private company, trailing only TikTok parent Bytedance, which is worth $140 billion, according to CB Insights.

In a scene from season one, Jim Holden shows exquisite command of high school physics as he maneuvers himself onto a spaceship gangway.
As a fan of science fiction and science, I have to say that The Expanse has a bunch of great science. It’s not just the science in the show. The characters also seem to demonstrate an understanding of physics. One scene from the first season stands out in particular as a classic physics example.
I guess I should give a spoiler alert, but I’m not really giving away any major plot elements. But you have been warned.

Strongest and toughest glass known developed by McGill University scientists.
Scientists from McGill University develop stronger and tougher glass, inspired by the inner layer of mollusk shells. Instead of shattering upon impact, the new material has the resiliency of plastic and could be used to improve cell phone screens in the future, among other applications.
While techniques like tempering and laminating can help reinforce glass, they are costly and no longer work once the surface is damaged. “Until now there were trade-offs between high strength, toughness, and transparency. Our new material is not only three times stronger than the normal glass, but also more than five times more fracture-resistant,” says Allen Ehrlicher, an Associate Professor in the Department of Bioengineering at McGill University.

Most people don’t give a second thought to the poop they flush away. But perhaps they should, because the energy contained within our repellent remains is impressive.
If you let poop fester—and you probably shouldn’t in polite company—bacterial digestion will produce a methane-rich ‘biogas’ that can be harnessed for energy. You can also dehydrate a deuce to make powdery fuel or combustible bricks with a similar energy content to coal. These schemes may sound outlandish, but wastewater plants all over the developed world take advantage of this salvageable energy to subsidize their operations. One UK-based treatment plant, for example, gets 50 percent of its power using poop.
As adults live longer, demand for dental implants continues to grow. However, researchers at Kyoto University and the University of Fuki in Japan may be closer to finding a way to help adults continue to function with natural dentition.
According to the University of Fuki, scientists investigated the effects of monoclonal antibodies for USAG-1. Investigators focused on the USAG-1 gene that interacts with the two mechanisms responsible for tooth development — bone morphogenetic protein (BMP) and Wnt signaling. They found administering USAG-1-neutralizing antibodies affects BMP signaling only. The authors reports a single administration was enough to generate a whole tooth in mice and, in subsequent experiments, ferrets as well.

Four women have had new vaginas grown in the laboratory and implanted by doctors in the US.
A tissue sample and a biodegradable scaffold were used to grow vaginas in the right size and shape for each woman as well as being a tissue match.
🤔Will someone PLEASE get this man a seat on the next REAL SpaceX trip to space as a passenger already!? 🙄🙏
You’ll have to wait ever-so-slightly longer to see Star Trek actor William Shatner head to space. Blue Origin has delayed Shatner’s launch aboard NS-18 by a day to October 13th at 9:30AM Eastern following predictions of strong winds in West Texas. The rough weather was the “only gating factor,” Blue Origin said in a statement, noting that the passengers began their training today (October 10th).
Shatner’s flight is a publicity grab on multiple levels. It’s no secret that Jeff Bezos’ outfit is eager to have Captain Kirk reach space, but Shatner will also be the oldest person to make such a journey at 90 years old. The previous record-setter, aviation legend Wally Funk, traveled aboard a Blue Origin flight at 82 years old. Other passengers include Blue Origin mission VP Audrey Powers and two corporate executives, Planet Labs’ Chris Boshuizen and Medidata’s Glen de Vries.

Going to the bathroom becomes more challenging when you are in space. Check here how the astronauts empty their bladders and stomachs in space.

NASA is developing a spacesuit with a built-in toilet system, something the agency hasn’t used regularly since the Apollo era.
It’s the question we all want to know the answer to… what are the toilets like in space?
Well never fear the answer is here… NASA have just spent over $23 million dollars (£16 million) on a brand new toilet!
Going to the toilet is a basic human need but when you’re in space with a lack of gravity things can get a bit tricky, but it’s about to get easier.
