Thank you so much @rosieofcorona and @vivispec for your encouragement and advice with this one🩵🩵🩵

I'm so excited!!

A speedpaint video of this will be available at my Patreon soon!

Me and my boyfriend (I'm the freak)

beautiful gorgeous ethereal man x little freak he would do anything for

Okay these thoughts are destroying my soul from the inside so lemme explain exactly why this page is fucking everything to me.

Stan's endlessly devoted to Xeno. He's proven this time and time again, he'd go to the ends of the earth and personally burn it all down just for this man.

They lost the fight. They were petrified again. It could have very easily been their last moments alive. But he wakes up, and the first thing he sees is Xeno, looking at him with those big, excited eyes, giving him a job. He's unsure what's happened while he was stone, how long Xeno's been awake without him, at the mercy of the KoS. But Xeno looks good. Healthy. Clearly, for however long he's been "captive," Xeno's been safe.

Stan's first move is to grab him. He's so gentle as he wordlessly checks him over for any sign of harm, but there's none. In fact, Xeno's got this earnest brightness Stan hasn't seen on him in thousands of years, back when they were kids. Maybe it's the change of scar, but he seems so much lighter now. They so clearly treated Xeno well, let him do his science and gave him a purpose, let him fulfill his passions. They gave him some of his hope back.

Of course Stan's going to take this mission. It's the least he can do after all they've put these kids through, and they still were so good kind to Xeno. He owes them this much. (Though, if Xeno asked him to, he probably would have gone right back to the war room. Bro's devoted.)

And like, on Xeno's side, the touch makes his expression change completely. He drops his guard just a bit, because oh my science did he miss Stan.

Xeno says nothing. He understands that Stan needs this moment, this confirmation. And he absolutely needs it to, he's missed Stan so much. Holding himself back from reviving Stan has obviously been painful. He's visited Stan's statue often, taken care of him, but he hasn't allowed himself to bring him back. Not yet. Maybe he knew it would be too tempting, and he wanted to ensure he followed these kids' pipe dream to the end before he gave in and went back to the world domination plan. But their dream became reality, and now he gets Stan back, and he just looks so happy oh my god. Gen was right, even though the scientists aren't the type to show it, Xeno and Stan's separation has been eating the dr up inside. Somewhere along the way he gave up on conquering the world and he just wanted to do science and solve this mystery and get his knight back.

And the way he's so devoted to Stan as well, showing it not with mushy flowery words but with how he showers him with gifts, makes sure he has everything he could ever want or need, just as long as he stays by Xeno's side. Xeno knows he's a weight on Stan's shoulders, so he makes up for it wherever he can, but to Stan it's not a burden, it's his life partner.

Bonus panel cuz i thought it was adorable

Look at Xeno's lil necktie! And he hasn't been able to give Stan makeup yet. Stan looks so fond i just!!! They're so good your honor they love each other so much.

A little Solavellan comm ✨

In Another World.

Yeah, I landed in solavellan hell. I even made a playlist.

I missed them.

Yes and xeno shaves his undercut :(:(:(:( u cannot separate them

My theory about why Xeno's pompadour got so big in the latest arcs is bc Stanley was the on that did his hair, and without him Xeno did the best he could :'(

don’t try it

all (?) from my colored Stanley collection

I find it cute how they keep switching hair colors with every official art

I always heard he was a marine, but he's air force?

I got a new dr stone book that’s basically a recap of every character’s life.

So here’s a little recap of Stanley pre petrification (obviously).

0yo (1993)= Born in the USA. (very useful info luv it.)

10yo (2004)= Become the youngest person to win a local shooting competition.

11yo (2005)= He meets Xeno and helps him in the development of a rail gun, serving as gunner.

16yo (2010)= He makes Xeno win a bet by managing to shoot an American football in movement. (the money of the bet helped Xeno fund his research.)

18yo (2012)= He enters the US air force.

19yo (2013)= Because of his excellent performances he is assigned to special forces.

22yo (2015)= He excels in his every missions and becomes the youngest commander of the special forces

25yo (2019)= He gets petrified for the first time at D.A.R.P.A

Rockets, Racecars, and the Physics of Going Fast

When our Space Launch System (SLS) rocket launches the Artemis missions to the Moon, it can have a top speed of more than six miles per second. Rockets and racecars are designed with speed in mind to accomplish their missions—but there’s more to speed than just engines and fuel. Learn more about the physics of going fast:

Take a look under the hood, so to speak, of our SLS mega Moon rocket and you’ll find that each of its four RS-25 engines have high-pressure turbopumps that generate a combined 94,400 horsepower per engine. All that horsepower creates more than 2 million pounds of thrust to help launch our four Artemis astronauts inside the Orion spacecraft beyond Earth orbit and onward to the Moon. How does that horsepower compare to a racecar? World champion racecars can generate more than 1,000 horsepower as they speed around the track.

As these vehicles start their engines, a series of special machinery is moving and grooving inside those engines. Turbo engines in racecars work at up to 15,000 rotations per minute, aka rpm. The turbopumps on the RS-25 engines rotate at a staggering 37,000 rpm. SLS’s RS-25 engines will burn for approximately eight minutes, while racecar engines generally run for 1 ½-3 hours during a race.

To use that power effectively, both rockets and racecars are designed to slice through the air as efficiently as possible.

While rockets want to eliminate as much drag as possible, racecars carefully use the air they’re slicing through to keep them pinned to the track and speed around corners faster. This phenomenon is called downforce.

Steering these mighty machines is a delicate process that involves complex mechanics.

Most racecars use a rack-and-pinion system to convert the turn of a steering wheel to precisely point the front tires in the right direction. While SLS doesn’t have a steering wheel, its powerful engines and solid rocket boosters do have nozzles that gimbal, or move, to better direct the force of the thrust during launch and flight.

Racecar drivers and astronauts are laser focused, keeping their sights set on the destination. Pit crews and launch control teams both analyze data from numerous sensors and computers to guide them to the finish line. In the case of our mighty SLS rocket, its 212-foot-tall core stage has nearly 1,000 sensors to help fly, track, and guide the rocket on the right trajectory and at the right speed. That same data is relayed to launch teams on the ground in real time. Like SLS, world-champion racecars use hundreds of sensors to help drivers and teams manage the race and perform at peak levels.

Knowing how to best use, manage, and battle the physics of going fast, is critical in that final lap. You can learn more about rockets and racecars here.

Here's a rare mind blowing moment in the astronomy world. Clearest images ever taken of Equatorial Ridge on Saturn's moon 'Iapetus'.

"There was an exchange on Twitter a while back where someone said, ‘What is artificial intelligence?' And someone else said, 'A poor choice of words in 1954'," he says. "And, you know, they’re right. I think that if we had chosen a different phrase for it, back in the '50s, we might have avoided a lot of the confusion that we're having now." So if he had to invent a term, what would it be? His answer is instant: applied statistics. "It's genuinely amazing that...these sorts of things can be extracted from a statistical analysis of a large body of text," he says. But, in his view, that doesn't make the tools intelligent. Applied statistics is a far more precise descriptor, "but no one wants to use that term, because it's not as sexy".

What We Learned from Flying a Helicopter on Mars

The Ingenuity Mars Helicopter made history – not only as the first aircraft to perform powered, controlled flight on another world – but also for exceeding expectations, pushing the limits, and setting the stage for future NASA aerial exploration of other worlds.

Built as a technology demonstration designed to perform up to five experimental test flights over 30 days, Ingenuity performed flight operations from the Martian surface for almost three years. The helicopter ended its mission on Jan. 25, 2024, after sustaining damage to its rotor blades during its 72nd flight.

So, what did we learn from this small but mighty helicopter?

We can fly rotorcraft in the thin atmosphere of other planets.

Ingenuity proved that powered, controlled flight is possible on other worlds when it took to the Martian skies for the first time on April 19, 2021.

Flying on planets like Mars is no easy feat: The Red Planet has a significantly lower gravity – one-third that of Earth’s – and an extremely thin atmosphere, with only 1% the pressure at the surface compared to our planet. This means there are relatively few air molecules with which Ingenuity’s two 4-foot-wide (1.2-meter-wide) rotor blades can interact to achieve flight.

Ingenuity performed several flights dedicated to understanding key aerodynamic effects and how they interact with the structure and control system of the helicopter, providing us with a treasure-trove of data on how aircraft fly in the Martian atmosphere.

Now, we can use this knowledge to directly improve performance and reduce risk on future planetary aerial vehicles.

Creative solutions and “ingenuity” kept the helicopter flying longer than expected.

Over an extended mission that lasted for almost 1,000 Martian days (more than 33 times longer than originally planned), Ingenuity was upgraded with the ability to autonomously choose landing sites in treacherous terrain, dealt with a dead sensor, dusted itself off after dust storms, operated from 48 different airfields, performed three emergency landings, and survived a frigid Martian winter.

Fun fact: To keep costs low, the helicopter contained many off-the-shelf-commercial parts from the smartphone industry - parts that had never been tested in deep space. Those parts also surpassed expectations, proving durable throughout Ingenuity’s extended mission, and can inform future budget-conscious hardware solutions.

There is value in adding an aerial dimension to interplanetary surface missions.

Ingenuity traveled to Mars on the belly of the Perseverance rover, which served as the communications relay for Ingenuity and, therefore, was its constant companion. The helicopter also proved itself a helpful scout to the rover.

After its initial five flights in 2021, Ingenuity transitioned to an “operations demonstration,” serving as Perseverance’s eyes in the sky as it scouted science targets, potential rover routes, and inaccessible features, while also capturing stereo images for digital elevation maps.

Airborne assets like Ingenuity unlock a new dimension of exploration on Mars that we did not yet have – providing more pixels per meter of resolution for imaging than an orbiter and exploring locations a rover cannot reach.

Tech demos can pay off big time.

Ingenuity was flown as a technology demonstration payload on the Mars 2020 mission, and was a high risk, high reward, low-cost endeavor that paid off big. The data collected by the helicopter will be analyzed for years to come and will benefit future Mars and other planetary missions.

Just as the Sojourner rover led to the MER-class (Spirit and Opportunity) rovers, and the MSL-class (Curiosity and Perseverance) rovers, the team believes Ingenuity’s success will lead to future fleets of aircraft at Mars.

In general, NASA’s Technology Demonstration Missions test and advance new technologies, and then transition those capabilities to NASA missions, industry, and other government agencies. Chosen technologies are thoroughly ground- and flight-tested in relevant operating environments — reducing risks to future flight missions, gaining operational heritage and continuing NASA’s long history as a technological leader.

You can fall in love with robots on another planet.

Following in the tracks of beloved Martian rovers, the Ingenuity Mars Helicopter built up a worldwide fanbase. The Ingenuity team and public awaited every single flight with anticipation, awe, humor, and hope.

Researcher discovers 1 in 5 bacteria can break down plastic

Leiden Ph.D. candidate Jo-Anne Verschoor discovered that nearly 20% of the bacterial strains she studied could degrade plastic, though they

Leiden Ph.D. candidate Jo-Anne Verschoor discovered that nearly 20% of the bacterial strains she studied could degrade plastic, though they needed some encouragement to do so. "Bacteria are just like people," says Verschoor. Her research was published in the journal Communications Biology. Some of the world's smallest organisms could play a significant role in solving the problem of plastic pollution. Increasingly, it is being discovered how certain bacteria can break down plastic into small particles, which can then be recycled. Moreover, Verschoor's research reveals that many more bacteria than previously thought can degrade certain types of plastics. The 27-year-old Leiden microbiologist was able to use a large collection of Streptomyces bacteria, which were already available at the university as scientists use them in the search for new antibiotics.

Unpopular Opinion:

*Dr. Stone SPOILERS if you haven't read the manga*

I don't think Senku romantically likes Kohaku or anyone. In the beginning he says to Taiju, "You've liked her for 5 years and haven't told her how you felt? I can't praise such illogical behavior." He would be the type to tell someone he likes them if that's how he feels, because that's what's logical to him. By Taiju and Yuzuriha's wedding he's known Kohaku for, what, minimum 10 years if not more? And instead he consistently replies with "I don't have time for that" and doesn't reciprocate affection. Also, doesn't her being like 'I'll marry you' sound exactly like when she said she'd marry Chrome? And we know she wasn't serious then. No matter how many tidbits they try to give us with Kohaku (mostly just then standing close to eachother) it always feels incredibly one-sided. Haphazardly thrown in to please someone... the studio, the readers? idk

They consistently made it seem like Kohaku and Senku weren't a thing then kept trying to make it seem like they kinda-sorta could be in the end? When it could all be interpreted in the "It's not like that between them. Not like that" way that they pushed earlier on? Why do that? I don't know if it's just a shonen writer not getting it or him being pressured to sprinkle it in by their editor or whoever but my interpretation is that Kohaku likes Senku but he doesn't like her back. He's shown to be a direct, straightforward, and logical guy. He wouldn't lead someone on or be aloof or cryptic if he liked them.

Because of these mfs I'm still mentally recovering after reading America arc
