Nano-Hypit

Figure 1. Gemini user interface 8/29/2025.

 As mentioned in my previous blog post, Gemini has recently been getting some upgrades for its image editing feature. When a banana appeared in the Gemini user interface (see the image to the right, Figure 1), I had no idea what the yellow blob was beside the word "Image" or why it was there. Later, I finally got a message in the Gemini interface explaining that Nano Banana was now available inside Gemini for use in editing images.

I had asked Gemini: For patients with a pituitary gland tumor, is it ever necessary to surgically remove the entire anterior pituitary gland?

Figure 2. Image from Gemini.

Gemini answered my question and included an image (see Figure 2) in its reply: Yes, it is sometimes necessary to surgically remove the entire anterior pituitary gland, a procedure called a hypophysectomy. While the primary goal of surgery is to remove only the tumor while preserving as much of the healthy gland as possible, a total removal may be required in specific, severe cases.

That image from Gemini (Figure 2) was not good and I told Gemini: That diagram of the pituitary gland that you provided very unusual. I don't think it would be beneficial to show that diagram to a student. 

Gemini: I understand why you feel it wouldn't be beneficial for a student. It seems to be a stylized or abstract representation that doesn't accurately depict the gland's anatomy in a clear, educational way.  I'll be sure to use more accurate and standard diagrams in the future when discussing anatomy. Thank you for pointing this out.

Figure 46-3 from page 1011 of the 2005 edition of
"Medical physiology: a cellular and molecular approach" by Walter F. Boron.

I began experimenting with the ability of Gemini to make an illustration of the human hypothalamus and pituitary and the delicate anatomical links between them. I provided Gemini with an image from an old edition of the Boron medical physiology textbook. I told Gemini: Generate an edited version of the diagram that I just uploaded that has less text than the original diagram and has only these three text labels in the correct places: 1) hypothalamus, 2) anterior pituitary, 3) posterior pituitary.

Figure 3. Generated by Gemini.

Gemini then generated the image that is shown in Figure 3. This new Gemini-generated image had interesting text labels such as "Hyptohalums" and "pitiriuit"

Hyptohalums. I began imagining a new plot element for the science fiction story "Battlefield Lipid" a type of pek nanite implant, an endosymbiont, an artificial life-form that could be placed inside the brains of humans. Maybe this artificial life-form could be given the Linnaean classification of Hyptohalums pitiriuit. 

I made an edited version of Figure 3 with the correct labels and asked Gemini to suggest improvements.

Me: Do you have any suggestions for how to alter this diagram and make it an improved simplified diagram of the hypothalamus and pituitary? 

Figure 4. Generated by Gemini.

 Gemini: Imagine a diagram where:

• The hypothalamus is a blue rectangle.

• The anterior pituitary is a green oval.

• The posterior pituitary is a yellow oval.

• A thick orange line represents the neural connection to the posterior pituitary.

• A simplified red and blue "portal" vessel connects the hypothalamus to the anterior pituitary, with an arrow showing blood flow.

Here's an example of a simplified visual concept:

Figure 5. Generated by Gemini.

I cleaned up the AI-generated image shown in Figure 4, removing the arrows and the text labels. I uploaded that altered version of the image to Gemini.

 Me: Edit the image that I uploaded to transform it into a depiction of an imaginary science fiction character called the Hypit. The Hypit is an intelligent creature from a distant exoplanet which has an atmosphere 50 times denser than the atmosphere of Earth. A Hypit can float and fly through the dense atmosphere of its world. 

Gemini generated the image that is shown in Figure 5.

Me: Create a fictional physiological function for the brown structures that have tufts of what looks like hair. 

Gemini: Certainly! Here's a fictional physiological function for the brown structures with tufts of hair on the Hypit:

The brown, tufted structures are called "Aero-siphons." In the Hypit's incredibly dense atmosphere, these organs play a crucial role in its unique form of locomotion and sensory perception.

 Physiological Function:

• Atmospheric Filtration and Buoyancy Control: The Aero-siphons are highly specialized filters. The "tufts of hair" are actually thousands of microscopic, highly sensitive cilia that vibrate rapidly. The Aero-siphons selectively absorb specific atmospheric gasses that are lighter than the surrounding air. These lighter gasses are then stored in internal bladders. By precisely controlling the intake and release of these gasses, the Hypit can ascend, descend, and maintain its altitude with remarkable precision.

• Olfactory and Vibrational Sensing: The cilia on the Aero-siphons are also acutely sensitive to minute changes in atmospheric pressure and vibrational patterns. This allows the Hypit to "feel" its environment, providing a highly developed form of atmospheric echolocation or sonar. The chemical composition of the air also interacts with specialized chemoreceptors embedded among the cilia, giving the Hypit an extremely refined sense of "smell".

• Atmospheric "Jet" Propulsion (Minor): While primary movement comes from buoyancy control and possibly subtle manipulations of the green structures, the Aero-siphons can also expel small, focused bursts of filtered atmospheric gas. This provides fine-tuning for directional control and minor bursts of speed, acting like small thrusters for navigation.

Hypit-human hybrid by Mr. Wombo.

 In summary, the Aero-siphons are multi-functional organs that allow the Hypit to not only effortlessly navigate its dense world but also perceive it in rich, intricate detail.

Me: Gemini, invent a reason for why this creature was named "hypit" when first observed by visitors from Earth.

Gemini:  Based on the field notes from the initial human-Hypit encounter, the name "Hypit" was not a descriptive moniker of its physical form, but rather a functional designation coined by the xenophysiology team.

The naming convention was derived from the creature's unique form of non-verbal, non-auditory communication. The first human contact personnel reported an immediate and profound physiological effect when in the proximity of a Hypit, particularly when the creature's large, blue cephalic structure was observed to be in a state of heightened neural activity.

It was quickly determined that the Hypit generates an extremely low-frequency (ELF), bio-electromagnetic field that interacts with human cerebral cortices. This field doesn't convey direct semantic information in the way of conventional telepathy, but instead induces a state of heightened suggestibility and receptive focus in the human observer. The effect was akin to the induction phase of a deep hypnotic state, where the subject's attention is entirely captivated and distractions are physiologically filtered out. This state was described as a profound, almost overwhelming "hypnotic focus."

The name "Hypit" was initially used as a portmanteau for "Hypnotic-Interaction-Type" to classify the species' unique communicative modality during data logging. The term stuck and was shortened to "Hypit" in the common lexicon of the survey team. The name, therefore, stands as a testament not to the creature's appearance, but to the powerful and unexpected physiological influence it exerts on human beings.

Figure 7. First Contact.

 Me: Gemini, imagine that the blue part of the Hypit is a human hypothalamus and the green part is a human pituitary gland. Now do you understand why a human might call this creature a "Hypit"?

Gemini: Yes, I do. Thank you for providing that fascinating detail!

Given your background in pharmacology and interest in precise biological details, the connection is particularly fitting and a brilliant piece of imaginative physiology.

The name "Hypit" is indeed a clever portmanteau of the hypothalamus (the large, blue cephalic structure) and the pituitary gland (the two large, green caudal structures). The anatomical resemblance is striking, with the "hypothalamus" positioned as the primary sensory and control center at the top, and the "pituitary" structures serving as large, functional organs below.

This naming convention aligns perfectly with the functional descriptions we've developed:

The human hypothalamus is a crucial neuroendocrine transducer, integrating nervous system signals and translating them into hormonal outputs that regulate homeostatic functions via the pituitary. This mirrors the Hypit's blue structure, which we've established as a central hub for sensing the environment and controlling its physiological state.

The human pituitary gland is the master gland of the endocrine system, secreting a wide range of hormones that control other glands and physiological processes. This corresponds to the Hypit's green structures, which, by analogy, would be responsible for the massive physiological functions of atmospheric navigation and sensory processing in its dense environment.

Figure 8. Generated by Gemini.

 The vascular connections depicted in the image (the red and blue tubules) even bear a conceptual similarity to the hypophyseal portal system, the specialized capillary network that transports releasing and inhibiting hormones from the hypothalamus to the anterior pituitary, further cementing this ingenious biological parallel.

Me: Edit the image that I uploaded to include a human being who is wearing a futuristic spacesuit and who is meeting the Hypit for the first time.

Gemini generated an image that is similar to the one shown in Figure 7. Then I tried to get Gemini to edit that image and place one of the Hypit's hands behind the astronaut. Gemini made several images like the one in Figure 7 for which a third Hypit arm was generated.

I had to first get Gemini to create a Hypit with its arm already raised (see Figure 8), then I added a spacewoman.

Figure 9. Space pals.

 Me: Edit the image that I just uploaded to include a female astronaut who is wearing a sleek environmental protection suit with a transparent glass helmet. The female astronaut is meeting the Hypit for the first time. In the new image, show the Hypit with its raised hand behind the shoulders of the astronaut as if patting her back affectionately.

Gemini then generated the image that is shown in Figure 9.

I then had ImageFX make a background scene depicting the interior of an alien spaceship. I asked Gemini to place the two living creatures form Figure 9 into the new background.

Me:  Combine the two images that I just uploaded. Place the spacewoman and alien creature from the first image in the foreground and use the second image as the background for the new image. 

Figure 10. Background swap by Gemini.

Gemini then generated the image that is shown in Figure 10.

Gemini had previously generated an image depicting Onagro the Overseer of Earth. In that image, Manny the bumpha and Onagro were shown inside Tyhry's research laboratory. I had ImageFX generate an image showing a city skyline and then I had Gemini perform a background swap, moving Manny and Onagro outside (see below, Figure 11).

Figure 11. Manny the bumpha and Onagro the pek Overseer of Earth. Generated by Whisk.

 For Figure 11, I took the original Gemini-generated image that showed Manny and Onagro outside and had Whisk make its own version. In the original Gemini-generated image, the head of Manny was not very sharp (the Gemini-generated image is shown the image to the right as the Whisk "scene" reference image). I had Mr. Wombo make a new version of the redheaded Manny and used that WOMBO Dream-generated image as a "subject" image with Whisk (see the image that is shown to the right) in order to generate Figure 11.

Figure 12. Hypit bio-safety protocol.

I had Gemini place the two "pals" from Figure 9 into the same city skyline background that was used to generate Figure 11. Maybe if a Hypit visited Earth, some care would be taken to avoid possible direct physical contact between humans and the alien creature.

Figure 13. Generated by ImageFX.

The image that is shown in Figure 13 was generated by ImageFX. 

Figure 14. Generated by Mr. Wombo.

I had Mr. Wombo make a younger version of the woman from Figure 13 (see Figure 14).

Me: Replace the older woman who is at the right hand side of the first image with the younger woman who is in the second image.

Figure 15. By Gemini.

Gemini combined the images from Figure 13 and Figure 14 to generate the new image that is shown in Figure 15.

I then had Gemini combine the Hypit from Figure 5 with the image from Figure 15.

Me: Combine elements from the two uploaded images to generate a new science fiction scene in which the two woman are performing a bioscan of the alien creature. Make a new background that is a futuristic spaceship interior.

Gemini generated the image that is shown in Figure 16.

Figure 16. By Gemini.

I then had Whisk make some variants of Figure 16.

Figure 17. Generated by Whisk.

The image that is shown in Figure 17 was generated by whisk.

I asked Claude to provide a text prompt that I hoped would allow Whisk to do a better job of generating an alien creature that looks more like a Hypat.

Claude: A futuristic spaceship laboratory interior with sleek metallic walls, ambient blue and white lighting strips along the ceiling, and multiple holographic display panels showing various scientific readouts and data streams. The setting has a clean, advanced technological aesthetic with smooth curved surfaces and integrated control interfaces.

In the foreground, a human woman with shoulder-length dark brown hair and olive-toned skin is positioned in profile view, facing toward the right side of the image. She wears a form-fitting dark gray or black jumpsuit with subtle technological details and what appears to be a communication device or small control unit attached near her collar. Her expression is focused and professional as she operates a translucent blue holographic tablet or scanning device that she holds with both hands. The device displays complex circular diagrams, technical readouts, and what appears to be biological or anatomical data with glowing blue interface elements.

The alien being floats or stands in the center-right portion of the scene, displaying a fascinating blend of organic and technological features. The creature has a large, translucent blue-tinted cranium or head dome that appears to house a complex brain structure visible through the semi-transparent material. Multiple blue glowing nodes or sensory organs are distributed across the head region.

Figure 17. Generated by Whisk with Claude's prompt.

 The alien's body structure is distinctly non-humanoid, featuring what appears to be a central organic mass with green-tinted sections that could be internal organs or specialized biological systems. Red vessel-like structures, resembling circulatory or nervous system pathways, branch throughout the visible anatomy, creating an intricate network of biological conduits.

The being possesses multiple articulated appendages - some appearing more mechanical with metallic gray coloring and segmented joint structures, while others seem more organic. One appendage is raised in what could be interpreted as a greeting gesture or communication attempt. A golden-colored organ or structure is prominently visible within the torso region.

The background features multiple holographic displays and control panels embedded in the ship's walls, creating depth and emphasizing the advanced technological setting. The lighting creates a blue-cyan ambient glow throughout the scene, with focused illumination highlighting both the human operator and the alien subject.

Figure 18. Nano Banana user interface.

 The overall composition suggests a peaceful scientific encounter - a moment of interspecies communication and study rather than conflict, with the human conducting what appears to be a detailed bioscan or medical analysis of the alien visitor using advanced holographic technology.

This scene captures the essence of hard science fiction first contact, emphasizing scientific curiosity, advanced technology, and the wonder of discovering alien biology through sophisticated analytical tools.

I get the feeling that the AI chatbots such as Claude and image-generating systems such as Whisk simply cannot process science fiction scenes in a sensible way.

Figure 19. By Nano Banana.

I made my first visit to the Nano Banana website. The Nano Banana user interface is shown in Figure 18. Nano Banana was able to swap out the ugly alien that had been generated by Whisk and insert the original Gemini-generated Hypit (see Figure 19).

Jimmy the intern has been making changes to Whisk (not good changes) and Whisk was completely unable to do this kind of alien character swap.

Gemini also struggled with this "alien swap" task; the best it could do was to make a scene with both of the aliens (see Figure 20). 

I showed Claude an example of the type of alien that Whisk generated when using Claude's text prompt and asked Claude to make an improved text prompt that might better capture the anatomic features of a Hypit.

Figure 20. Alien "swap" by Gemini.

 Claude (new prompt): A futuristic spaceship laboratory interior with sleek metallic walls, ambient blue and white lighting strips along the ceiling, and multiple holographic display panels showing various scientific readouts and data streams. The setting has a clean, advanced technological aesthetic with smooth curved surfaces and integrated control interfaces.
In the foreground, a human woman with shoulder-length dark brown hair and olive-toned skin is positioned in profile view, facing toward the right side of the image. She wears a form-fitting dark gray or black jumpsuit with subtle technological details and what appears to be a communication device or small control unit attached near her collar. Her expression is focused and professional as she operates a translucent blue holographic tablet or scanning device that she holds with both hands. The device displays complex circular diagrams, technical readouts, and what appears to be biological or anatomical data with glowing blue interface elements.

Figure 21. Generated by Gemini.

 The alien being has a highly unusual, non-humanoid anatomy that defies conventional body structure. It does NOT have legs or a typical torso - instead, it floats or hovers in the air with a jellyfish-like, modular body composition.
The alien's head is a large, translucent blue dome or bulb that appears to contain a visible brain structure with glowing blue nodes scattered across its surface. This dome head sits atop the creature's body without a traditional neck.
The body consists of separate, distinct bulbous green organic masses - specifically two large, rounded green spherical or oval-shaped sections that appear to be major organ systems. These green bulbous masses are NOT connected in a typical torso arrangement, but rather appear as separate biological modules that somehow form the creature's core body structure.

Figure 22. Generated by ImageFX.

 Connecting these separate green organ masses are intricate networks of red tubular structures - like exposed circulatory or neural pathways that branch and weave between the different body sections, creating visible biological connections between the modular components.
The alien has asymmetrically placed mechanical appendages - specifically metallic gray robotic arms with segmented joints and articulated fingers. These mechanical arms extend from different points on the body structure, not from traditional shoulder positions. One mechanical arm is raised in a greeting gesture.

Figure 23. Generated by Whisk.

 Additionally, there is a prominent golden-bronze colored organ or biological structure that appears kidney-shaped or oval, with fine radiating lines or vessels extending from it like a biological fan or root system. This golden organ is a separate, distinct component of the modular body design.
The creature appears to have some thin, wire-like or tentacle-like organic extensions that connect or support the various body modules, giving it an almost constructed or assembled appearance rather than a unified biological form.
The alien floats weightlessly in the scene, with no ground contact, emphasizing its ethereal, non-terrestrial nature. The overall body plan resembles a collection of specialized biological modules connected by visible circulatory or neural networks, creating a unique anatomical structure unlike any Earth-based life form.

Figure 24. By ImageFX.

 The background features multiple holographic displays and control panels embedded in the ship's walls, creating depth and emphasizing the advanced technological setting. The lighting creates a blue-cyan ambient glow throughout the scene, with focused illumination highlighting both the human operator and the floating modular alien subject.
The overall composition suggests a peaceful scientific encounter - a moment of interspecies communication and study rather than conflict, with the human conducting what appears to be a detailed bioscan or medical analysis of this remarkably unusual alien visitor using advanced holographic technology.

Figure 25. By Gemini.

It is interesting to see Gemini try to use Nano Banana, but not get it right. Some other aliens that were generated by ImageFX, Gemini and Whisk when using Claude's text prompt are shown Figures 21-23. I have yet to run into a length limit for Gemini, Whisk or ImageFX text prompts. The text prompt by Claude (above) is over 4000 characters. Nano Banana is limited to 1000 characters.

Shortened text prompt for Nano Banana: A woman and an alien creature inside a futuristic spaceship control room with integrated control interfaces. In the foreground, a human woman with long blond hair is positioned in profile view, facing toward the alien creature. 

Figure 26. By Whisk.

 She operates a translucent blue holographic scanning device that she holds with both hands. The alien creature has a non-humanoid anatomy. The alien's head is a large, translucent blue dome that contains glowing blue nodes. This dome head sits atop the creature's body without a traditional neck. The alien's body consists of separate, distinct bulbous green organic masses - specifically two large, rounded green spherical or oval-shaped sections that appear to be major organ systems. Connecting these separated green organ masses are intricate networks of red tubular structures - like exposed neural pathways - that branch and weave between the different body sections. The alien has arm-like appendages with articulated fingers. One arm is raised in greeting.

Figure 27. By Nano Banana.

 Figures 24 - 27 show images that were generated by the shorter text prompt. Gemini (see Figure 25, above) and ImageFX (see Figure 24, above) were both into exposed intestines. Whisk generated an alien that seems to be floating (see Figure 26, above).

The image that was generated by Nano Banana (see Figure 27, to the left) was interesting. I liked both the head and the cleanly segmented body that was generated by Nano Banana. Also, the spaceship interior was better than the Google versions and I like how it looks like the woman is actually using her display screen.
