Iron fusion. Fusing light atoms is exothermic. Fusing iron and heavier atoms is endothermic. https://www.as.utexas.edu/~chris/stardatearticle.pdf The fusion reactions that make elements heavier than iron are endothermic — that is, they use up more energy than the reaction gives off. So “when you get an iron core,” Sneden says, “it sucks energy in and ...

I just came across this question and I have a fairly simple answer. Your predator takes a bath before it hunts. The predator jumps in the water or in the mud and drastically cools their skin and\or fur. At the same time, surface vessels constrict to conserve body heat. Thus you end up with a very cold skin on the predator. If you view it in infrared it just ...

The one thing in terms of movement i think everyone forgot is how large this creature is. If it manipulates its mass just right then it can probally physically change its mass in specific ways to effect its own gravity. By shifting its body the right way it could probally create literal gravity sinks and use the gravity to accelerate its body. If it does ...

Plausibility Is there energy in trees? yes. Wood fires are a thing. Is there much completion for trees as food source.Not much. Only some insects. The most plausible is a ruminant switching to a progressively woodier diet, It would require getting bacteria that can digest wood fiber and lignin, that are able to live in a ruminant digestive system. More ...

Evolutionary history would seem to indicate that the trees get bigger and faster growing. The sauropods were the huge tree eating dinosaurs that seem to have driven the evolution of species like the redwood and giant sequoia which simply outgrow the ability of even those multi-tonnes browsers to reach their foliage.

On average wood contains around ten times more calories per kilogram than fruits or leaves Having ten times the potential calories isn't very informative, if the energy required to break down those complex structural carbohydrates is more than ten times the energy required to digest fruits or leaves. Cellulose is already a problematic material to break down....

Growing wood takes also lot of energy. If it would be consumed easily, it probably wouldn't be worth growing, because the tree needs time to harvest the needed energy. Grass and leaves can be grown quickly, and praire grass for example has evolved to be grazed, but the growth rate of grass is not comparable to the one of wood. Unless the trees could grow ...

This is a very interesting concept, and to me it seems like it's honestly not particularly far fetched. In terms of asking how this behaviour could evolve, you have to ask how it benefits the falscales, and you've already provided some answers. Firstly, by replacing and mimicking dragon scales, the falscale disincentivises the dragon removing them because ...

If a horde of these creature could emit into their environment hydrochloric acid (HCl, or stomach acid) and baking soda (NaHCO3, a dry powder) they could create an area where the temperature would drop considerably. Creating an high pressure pocket of carbon dioxide filled air that would spread outwards. Creating both a sudden temperature drop and a chocking ...

There is one BIG problem - back loop - many of the unprivileged would hate those privileged and many of them would hide it, to avoid repression. But as you said they are equivalently inteligent, so many would be able predict their fate and place (knowingly or not) some "bomb/virus/hidden agenda" in their brains (from "must help those poor"...

DWKraus has an excellent suggestion, but it does not explain the hardened scar formation. A bit of biological engineering, however, suffices to explain the hardened rubber scars. Latex is a natural compound produced by many plants, and it is used as a defensive coating against insects, infections and bacteria. However, it is a liquid. One more step is needed....

Peroxidase and hydrogen peroxide: This is alien biology, so anything IS possible. But why not stick to what we know? The aliens are encrusted in a thick biological coating filled with bacteria. The aliens get a fair amount of protection from this, but when they are actually penetrated, the bacteria are very dangerous for causing infections. They have an ...

Reject monkey-tailed cats, embrace displacer beast tentacles The critter above is a displacer beast, a creature from a classic ttrpg game called dungeons and dragons, and I'm not only using it due to a recent addiction to the game, but because if nature is anything to go by, the best anatomical option for something that is very flexible yet very strong is ...

Falscale bugs, like dragons, started from a "lesser" species, evolving from a parasites that fed by attaching themselves to lesser creatures. Over time it develops the ability to mimic its victims skin or scales. Thus giving it a better chance to remain undetected. The tougher the bugs shell is obviously the better its chance to resist attempts at ...

If nature selects it When studying biology, one of the biggest advantages of creatures who undergo metamorphosis, especially in insects which undergo full metamorphosis, is precisely that the young and the adults do not occupy the same niche. Look at dragonflies for example. They're born predators and die as predators (eaten as prey many times, but predators ...

Play it like the US Navy The US Navy deposed a patent for a device that does exactly what you're asking, by replaying the song emitted by the speaker twice, once almost simultaneously and once a bit later.

Since the process isn't possible (and, incidentally, probably never will be), you get to invent your own process, with whatever features you need. For example, let us say that the knowledge (e.g. words in a book) need to be, for want of a better term, "digested" to become a series of neural weights and connections, that (this is the unrealistic ...

"Knowledge from every person in the second group is then transferred to everyone in the first" A slight frame challenge in as much as only one person gets the skills from one of the 'underclass'.

I would like to point out an interesting phenomenon that might not (at first) seem entirely relevant. I am reminded of an experiment made with an FPGA a few years back. For those of you unaware, an FPGA is a special kind of computer chip that doesn't do anything specific. Most chips have paths etched into their silicon that makes them do one thing and one ...

Really, Really, Really big fins This is pretty much the only thing I could think of. Magnetic fields do not significantly affect water, definitely not enough for an organism to make waves. The best way this organism could move water is with giant fins. This is an image of an Killer whale making a wave to kill a seal So if your organism was something similar,...

Thinking of manipulating a lot of water my first thought is the moon and the north sea tides- aka gravity manipulation. Now your creature could maniplulate the orbit of the moon, but it might as well just create extra gravity itself (e.g. by creating a controlled black hole but idk how to realistically give your creature the ability to control a black hole -...

I'd suggest reading How to Create a Mind by Ray Kurzweil. I also suggest re-reading [Gödel, Escher, Bach] by Douglas Hofstadter, specifically the part about network congruence (USA vs ASU). Many stories simply propose your premise as a trope, giving the rules and ramifications without any detailed explanation of the technology. In order to explain, I would ...

If your people live in both environments it would be pretty great to be able to adjust their centre of gravity and maybe even their weight to whatever environment they are currently in, which could be done by an ability to retain water in different areas of the body for example, making them and yourself heavier or lighter depending on the environment.

mucus-coated bodies (scales, gills, eyes, everything) Where we're going, we won't need eyes. Or gills, for that matter. breathing through either symbiotic bacteria (which produce oxygen inside their gills or swim bladder) or by tapping into the host's bloodstream with special fangs, whichever is more feasible. There's a good reason why more conventional ...

Electric Eel nerve cells Most nervous cells in the animal kingdom discharge once a while regardless of what's happening. An Electric Eel is different.

It's fine as superpowers go, but decide what the limits are As the other answers say, you can probably get away with hand-waving it. Maybe you want it to work for bullets - that's no harder to explain than actual flying. But decide what the limits are. Maybe it can stop a handgun, but not a sniper round. Maybe it can't stop an aeroplane, maybe it can. If you ...

It sounds like a modified version of, or rather based on, a piezoelectric crystal: kinetic energy deforms the crystal, the deformation produces a difference of potential and the difference of potential is transferred to some chemicals which store this energy. The main problem seems to be the transfer rate: a punch or a blow have a very short duration, and ...

Very tribalistic While there may be some genetic mixing, your clone has to be pretty much the same dimensions as you. I'd imagine most phenotypes would be shared between the two. More importantly, if memories are carried over it stands to reason that dogma is transferred over from birth. Wrongdoing from generations ago could carry over as what feels like ...

With minimal hand-waving you can do it. I don't believe there are any natural examples of biological organisms converting (non thermal) kinetic energy into chemical energy. However, since we're talking about super powers, a certain amount of hand-waving may be allowed. If so all you really need to say is that your character's muscles are reversible. Normally ...

"Taxonomy" isn't a method--it is the general name for the concept of classifying things. Three different taxonomic methods have been common in human history. First, there is "folk taxonomy"; it's the implicit taxonomy encoded in the common names for things, which differs between languages. This usually involves grouping things by their ...

A 4.6 g hummingbird has a wingspan of 117.5 (4.6 inches). For an average human female of 159.5 cm (5'2") tall and 53 kg (117 lb) to fly like one, it would need a wingspan of about 12.6 meters (41.4 feet), which is very impractical and wouldn't work. If it was much shorter, say 50 cm (1'7") tall and 1.6 kg (3.6 lb), it would still need a wingspan of ...

Use the good old square cube law. Weight is proportional to the volume of a body, thus the cube of the length. If your creatures are X times the length of your reference sample, a good first approximation of their weight, all the rest being the same, is $X^3$. To give you a numerical example, if they were 2 times as tall as a human, they would weigh $2^3=8$ ...

Ballast. Vocal cords need to vibrate in a specific range of frequencies to allow speech. Several illnesses cause the vocal cords to change their mechanics and cause "voice loss": by being covered in mucus, by being more or less taut, by being swollen -- or by having nodules on them. These latter are usually of a cancerous nature, but they achieve ...

Thermocouples require a thermal gradient, they turn the flow of heat from a hotter to a cooler region of the device into a voltage difference. On the other hand biological electrical generators work on the basis of pumping charged ions to produce a static charge of freed electrons.
