Mikey: What!?

Leo & Mikey: Baxter Stockboy?

Something that I find kind of funny is when Baxter reveals he's the one behind everything in the episode 'The Mutant Menace', Mikey & Leo both seem to have different reaction to seeing him again with Mikey looking shocked & horrified as if Baxter is a serious threat while Leo looks more annoyed & fed up about the whole situation.

Something that I was kind of wondering about is if Leo & Mikey having different reactions to Baxter might have been a hint that Baxter would have possibly ended up a more Mikey focused enemy of the Turtles, similar to how The Purple Dragons in Rise are more Donnie focused enemies of the Turtles, due to Mikey being Turtle the closest to Baxter's age.

Something that I was also kind of thinking about was how there was meant to be an episode where Baxter tricks Mikey into bringing a Mouser into the Lair as an electronic pet during season so & I sort of wonder if we had gotten the episode, if we would have seen Mikey & Baxter have more of a dynamic with each other.

Inside Mercury: What experimental geophysics is revealing about our strangest planet

Mercury doesn't give up its secrets easily. The smallest planet in our solar system is also one of the most extreme—a sun-scorched, metal-rich world with a puzzling magnetic field and lavas unlike anything found on Earth.

"We still don't fully understand how Mercury got to be the way it is," said Anne Pommier, an experimental geophysicist at Carnegie Science's Earth and Planets Laboratory (EPL). "But each new data point helps narrow down the possibilities."

In a recent Neighborhood Lecture, Pommier explored Mercury's past, present, and future—drawing on decades of research, new lab experiments, and the promise of a new mission on the horizon.

A planet that defies expectations

Mercury has long fascinated Carnegie scientists.

In 1903, the institution's Year Book noted that "observations of Mercury are much wanted." Decades later, planetary scientist George Wetherill—director of Carnegie's former Department of Terrestrial Magnetism (DTM, which is now part of EPL)—predicted Mercury's heavily cratered surface well before spacecraft confirmed it. In the 2000s, another DTM director, Sean Solomon, led NASA's MESSENGER mission, which orbited Mercury for four years and transformed our understanding of its surface and interior.

"All we know about this planet pretty much comes from two missions: Mariner 10 and MESSENGER," said Pommier. "Both of them raised as many questions as they answered."

One of the biggest: Why is Mercury so metal-rich? Its core makes up 60% of the planet's volume—compared to Earth's 15%. Some scientists believe it formed from metal-rich building blocks others think that early collisions stripped away much of its rocky mantle.

"We need more data from the field, more experiments, more modeling to see which hypothesis makes the most sense," said Pommier.

A new mission and new tools

Answers may soon be on the way. In 2025, the joint European-Japanese mission BepiColombo will begin orbiting Mercury. Its instruments will probe the planet's magnetic field, chemistry, and—most exciting for Pommier—electrical conductivity.

But interpreting that data requires something we don't yet have: a detailed understanding of how Mercury-like rocks behave under Mercury-like conditions.

To bridge that gap, Pommier's team creates analog materials that replicate Mercury's oxygen-poor—or "reduced"—geochemistry. In such environments, elements behave differently, forming unusual minerals.

"Mercury is a very reduced planet—completely unlike Earth," Pommier said. Its rocks are rich in sulfur and other elements that thrive in oxygen-poor environments, forming minerals like iron and calcium sulfides rarely seen on Earth

Making magma from scratch

To study Mercury's volcanic past, Pommier's collaborators synthesized Mercury-like glasses—artificial lavas based on MESSENGER data—and analyzed them using high-resolution tools including Raman spectroscopy, nuclear magnetic resonance (NMR), and electron microscopy.

The results revealed a striking difference. On Earth, lava is built from silicon-oxygen bonds that form sticky, polymer-like chains. On Mercury, sulfur bonds with silicon to create shorter, less connected silicon-sulfur structures.

"This radically changes their physical properties," said Pommier. "Sulfur breaks up those long chains and replaces them with shorter, less interconnected structures."

The upshot? Mercury's ancient lavas may have flowed more like syrup than tar. Former Carnegie postdoc Megan Mouser measured these viscosities and found them to be orders of magnitude lower than Earth's. That might help explain the planet's surprisingly smooth volcanic plains—though Pommier notes other factors could be involved.

Still, it underscores a broader truth in planetary science: atomic-scale chemistry can shape entire landscapes.

Simulating a magnetic past

Mercury's magnetic field is another mystery. Although weak, it's still active—surprising for such a small, slowly cooling planet. To explore why, Pommier and U.K.-based colleague Christopher Davies and his research group ran thousands of models simulating Mercury's core evolution over billions of years.

Only a narrow range of scenarios reproduced both the field we observe today and the magnetic signature detected in crustal rocks that formed 3.8 billion years ago. In these models, Mercury maintains its dynamo by slowly growing a solid inner core, while a thin convecting layer in the outer core continues to generate the field.

"We think the convecting region in the molten outer core is getting thinner and thinner," said Pommier, "which might explain why the field is so weak today."

The importance of fundamental research

The tools and techniques developed in Pommier's lab—such as high-pressure presses, spectroscopy, and thermal modeling—are also used in energy research, materials science, and electronics.

"Basic research leads to discoveries that not only tell us about Mercury," said EPL Director Mike Walter, "they also lead to technical advances that have applications to the real world."

Walter and Pommier both emphasized that foundational science—the kind that reveals what Mercury is made of or how a magnetic field forms—ultimately underpins the discoveries and technologies that shape our lives.

Pommier noted that her lab is always interested in philanthropic support from those who are interested in helping to advance a deeper understanding of planetary interiors.

Why Mercury still matters

In a universe full of rocky planets, the one that breaks all rules might be the key to understanding them all.

As astronomers discover more rocky worlds around distant stars, Mercury serves as a crucial benchmark—close enough to study, yet alien enough to challenge our ideas about how planets form and evolve.

"Mercury is so off—it has this huge core, weird chemistry, and a magnetic field that doesn't quite add up," Pommier said. "In a way, it's like an exoplanet in our own backyard."

And with BepiColombo on the way, scientists are gearing up for a new wave of discoveries. Experiments like Pommier's will be essential for interpreting what the mission finds.

"Once the data arrive, we'll have something to compare it all to. The new field observations will guide new experiments, building a feedback loop between lab and space."

In other words, the work is just beginning.

Captured during MESSENGER’s primary mission, the colors highlight differences in rock composition and texture that aren’t visible to the human eye. Light blues and whites trace fresh crater rays, dark blues mark low-reflectance material likely rich in opaque minerals, and tan areas show ancient lava plains—clues to a volcanic past scientists are still working to decode.

Mercury-like melts (right), enriched in sulfur, form shorter, less connected silicon-sulfur chains. This disruption leads to lower viscosity and dramatically different melt behavior.

T5 AKA "Thezeus 5" (1983) by Alan Dibley, Cheddar, UK. "The British finals of the [1983] Euromouse Contest were held at the Computer Fair at London's Earls Court. Alan Dibley's T4 gained victory from David Woodfield's KnownAim only because its fastest untouched run was shorter. KnownAim had made a shorter run still but had needed a helping hand round an awkward corner. T5 was also unveiled at the fair but once again reliability let it down." – Getting on to the right track, by John Billingsley.

"The lure of five free trips to Japan brought 14 micromice to Copenhagen for the 1984 European finals. … Alan Dibley brought T4, T5 and a Thezeus with revamped software. … T5 blundered on an awkward corner and failed to find the shortest path." – Top mouse, by John Billingsley, Practical Computing, November 1984.

"In Copenhagen, at Euromicro 1984 ... David Woodfield (Enterprise) and Alan Dibley (Thezeus-5) won travel prizes donated by the Japan Science Foundation to join teams from Finland and Germany in the Japanese 'All World' contest in Tsukuba, held in August 1985." – Alternative Robotics: Robat and Micromouse – the Cybernetic Challenge, by Professor John Billingsley, Practical Electronics, July 1986."

At Expo '85 in Tsukuba, "A disconsolate Alan Dibley had to explain to the audience that T-5 had leaped off a table and suffered a broken wing - the cover in which the wall sensors were mounted. Even with the help of the Japanese mousers (special thanks to Mr. Higasa) the necessary lining up and adjustments could not be made in time. T-5's servomotors had then been sacrificed in an attempt to help the Finns. T-6 had been left at the hotel in disgrace after its failure to qualify, leaving the visitors still with a zero score." – Micromice at Expo '85, by John Billingsley.

FEBUWHUMP DAY FOUR: HIVEMIND

CW: BLOOD, MAJOR CHARACTER DEATH

@febuwhump

Baxter Stockman had upgraded his mousers.

“Faster,” He had said. “Stronger. Better.”

“Able to kill within moments.”

Raphael hadn’t really absorbed the information. He had been too busy trying to decide whether it was more effective to throw his opponent over his shoulder, or into a wall(preferably a hard one).

So when Boxer-Braxer, whatever-gave a loud, terrible, impression of an evil laugh, and pressed a button on a remote control, he was all set to kick his ass.

He wasn’t set for an indefinitely long marathon all over New York City.

“Are- they-” Raphael sucked in a breath. “Still- on our- trail?”

“Unfortunately,” Donnatello answered, clutching a stitch on his side.

Michelangelo was uncharacteristically silent in an attempt to save his breath for running. Donnatello and Raphael glanced at him worriedly, unnerved by his lack of response.

Raphael made eye contact with his older brother. He tried to convey the message of ‘What’s the plan?’, but he probably looked more like ‘I’m depending on my older brother to get me out of this mess.’. Whichever Leonardo interpreted it as, he felt immensely relieved when his eyes hardened, blue pupils darting around, looking for escape. He raised a hand, pointing to a nearby water tower.

“We’ll climb on top of there,” He said, “And take a breather. Be careful, we don’t know what these new mousers are capable of.”

“Destroying stuff,” Michelangelo mumbled. “And being total pains in the ass.”

Raphael’s mouth twitched, but he didn’t comment.

Having reached the tall metal structure, Raphael brought up the rear as they climbed up the rusted ladder. Upon reaching the roof, Donnatello flopped down, taking care to not fall off.

“Ugh… I’m exhausted.” He sighed.

“No time for rest,” Leonardo warned. “They’re coming up the ladder.”

In a split second’s decision, Raphael realised that they weren't going to win, camping up here and fighting them until they were swarmed.

What if he…

“Raph, you better not be thinking what I think you’re thinking,” Michelangelo breathed, wide-eyed.

Raphael jumped off the tnk, into the swarm of mousers waiting below.

He crushed the first two, and stabbed the next with his sai.

Kick.

Stab.

Spin.

Repeat.

The steady rhythm of battle was almost comforting. He felt like he was in a trance.

A mouser jumped at his face, steel maw agape.

Well, if he was going down, at least he was going down saving his brothers.

The sharp blades closed down onto his neck, crushing his windpipe. Blood gurgled out of the wound, and Raphael found himself coughing and trying to breathe air that would never come.

Distantly, he registered his brother’s screams.

He collapsed to the concrete of the rooftop, metal feet treading over his body.

The electronic beeps and whirrs emitting from the small machines slowly faded into black…

Another "Puzzle Card" commission of six personalized sketch cards that I received earlier this year from talented Mexican artist Marco Carrillo based on the first Konami Teenage Mutant Ninja Turtles LCD electronic handheld game (released 1989 in North America, I think). The concept of the original game revolves around the Turtle/Turtles (the "sprites" all resemble Leonardo using a katana) braving the dangerous traps and enemies on ground and underwater to save April O'Neil held captive in “Shredder’s Asylum.” Marco expanded upon the concept to feature Raphael battling Mousers and Flap Jaws (top left), Leonardo with a defeated Foot Soldier (top middle), Shredder with April in the Asylum trap (top right), Michelangelo (bottom left), Foot Soldier getting destroyed by the "Turtle Cutter" trap (bottom middle), and Donatello acquiring a bomb (bottom right). Taken together, the puzzle has something of a relay system. For such a familiar video game to the generation of turtle-loving kids who grew up with the franchise, it's surprising to me how little love this thing gets in regards to fan-art tributes. Meanwhile, the infamous NES game is meme-worthy enough due to the "Dam Level" alone. But I'm glad I was able to help Marco bring this set to life!
