I am currently writing the world, setting and characters for a project of mine called the ORION Project - a story set in a dystopian America in the near future of 2050, where the government has tak...
So I'm pretty new to chemistry and all this, but my world involves superpowers, which of course involves immense energy to have the characters use these powers. However, I want to stay consistent w...
Sort of two questions here, but very related. One about whether a mammal-like animal could evolve to have a chitinous endoskeleton, I guess. Then a question of whether, if they grow horns, that ske...
I have a planet too far away from its sun for photosynthesis to work well, so the plants use chemosynthesis. But since they don't use sunlight, would they have any reason to grow above ground? Some...
While watching Biblaridion's Alien Biosphere series, an interesting point came up: in Biblaridion's fictional world, atmospheric hydrogen sulfide is used as an energy source for chemosynthetic bact...
The boom-bust cycle answer I took for my question: Sustainability of Regular Global Wildfires due to Oxygen Rich Atmosphere pends on the atmosphere being rich in oxygen but poor in CO2. I, however,...
Space explorers have landed on an Earth like planet and, to their surprise, the place is luscious and covered in life, to the point of resembling some earthly tropical atoll. What they don't know ...
So, turning people into stone. You only have to add reversibility to the mix, and it becomes the BEST paramedical tool available. But, what does petrification need to accomplish to become just tha...
Humans are not the fastest mammals on the planet, but for very long distances (more than 40 kilometers) we can overtake any species living on land. Except some dogs. The best runners on ultra-long...
I was thinking of a story with a Werewolf as a detective, using mostly conversational skills and his sense of smell to solve crimes similar to many of the UK types of detective stories (Morse, Lewi...
First time posting here but I would like to get some help with an issue I have. I have a planet that has 30% more gravity than earth. I have terrestrial animals with an exoskeleton, they stand at ...
So, vampires here are created from humans with the help of a stone mask. Now, they're supposed to be weak for two things: Having their brains destroyed Prolonged exposure to sunlight The first ...
Amino acids, the building blocks of proteins and, therefore, one of the key components of life as we know it. There are many amino acids in nature, but they all stem from the same basic structur...
I got an interesting answer to one of my questions and I would like to know some additional info. A myoneme (or spasmoneme) is a contractile structure found in some eukaryotic single-celled o...
So in my world there's a creature as big as a common rodent or as big as a rabbit in size. They live in packs, usually burrowed, but occasionally come to surface to get food. The alpha male is task...
I am workin on an ecosystem based on life within the rings of a planet. I will create creatures from single celled organisms, to algae/ lichen, plankton/worms and scales of predators leading to lar...
Could a measurable amount of isopropyl alcohol occur naturally in an otherwise reasonably earth-like atmosphere? And if so, what is the highest possible concentration that a human could survive lo...
Starting at the most basic of theoretical questions, is it chemically possible for these minerals to be deposited by an organic enzyme? I'm particularly interested in diamond because it's pure carb...
Previously, I asked about the plausibility of a sulphuric acid dragon. As it turns out, the answer was right on Wikipedia, namely a. thiooxidans and the snottie Snottites are highly acidic biof...
Photosynthesis has an abysmal efficiency with regards to converting solar energy into useful fuel for a plant, and I was wondering: 1) If it would be possible to engineer a plant to accept electri...
I'm Wyvera, a young female writer. I've been working on a science fiction project for more than a year now. This project, which I will eventually turn into a novel series, is supposed to remain as ...
Extremely low possibility, but if life synthesizes from scratch after life has existed on a planet for a few million years, would the two separate lineages be able to co-exist?
Could alien life use nitrous oxide, N2O, as its oxidizing gas, like oxygen on earth? What biochemical reactions would be needed to produce and utilise this gas? I've also heard conflicting messag...
So, aqua regia is a somewhat safe material for a living being to work with, but the problem is that it isn't metal enough. Somebody suggested in an answer to another question, that dragons would f...
Do you think it will become possible to create opposite sex clones in the future? A male clone from a woman or a female clone from a man? I think it will become possible. To create a female clone ...
I am writing a story where a person suffers from a medical condition where the gut produces too much of a liquid called diphosphane. Diphosphane is pyrophoric past a certain small concentration, an...
This lifeform is a carbon based humanoid that uses ammonia instead of water, breathes chlorine gas, and its body uses the mineral olivine to toughen its skin. Its blood is blue; apparently an ammon...
I am a giant, intelligent, fortress-like, plant-based organism, able to forge many structures, defenses and organisms from my flesh by altering my own DNA and rapidly growing new constructs wheneve...
Previous question: Proofing dragons against their acidic breath weapon 1/2: Smart Neutralizing Agent So, I decided to find an alternative breath weapon for my dragons, that maximizes destructive p...
On a terrestrial planet with a high amount of ammonia vapor in the atmosphere, would any organism have a strong enough incentive to develop some form of autotrophic chemosynthesis that derives ener...
So, dragons here use aqua regia (an acid that dissolves even gold) as their breath weapon. This acid is made up of the dragon's stomach acid and some nitric acid, stored in a separate organ. On to...
In a specialised organ, the Vesica Spirite, which in function and makeup resembles a cross between the Ventriculus and the Vesica Biliaris, the animal creates and stores potent spirits by the me...
The Old Ones build continent-sized bunker complexes to protect themselves from the enemy, which followed through the cosmic ocean. The Hunter succeeded easily despite their efforts and their corpse...
The limpet teeth's microscopic structure is analogous to man-made short-fiber composites. Its strength depends on the direction of the force, relative to the orientation of the fibers. https://www...
My question: What is it that needs to be improved or added to the human body so that it can withstand critically (fatally) low and high (if, my genetically modified person is underwater or a very d...
Question: does a liquid or gelatinous substance exist that once outside a body could solidify and be hard enough to be used once as a tool? The setting is low fantasy without magic, yet with creat...
Previous parts here: Creating a scientificly semi-valid super-soldier, part 1: Skeleton Creating a scientificly semi-valid super-soldier, part 2: nervous system Creating a scientificly semi-valid ...
One of the basic requirements for life is effectively food. One of the basic requirements of engineering is that we lift off with as little mass as possible. If we choose to explore the solar syst...
I have an alien species similar to a caterpillar, the original idea was that the creature could eat different materials, digest them then combined with a very sticky liquid created in its body, it ...
Is there an example of substances interacting with each other in the following way? A is a lethal substance, killing within minutes to hours when orally ingested; anti-A is an antidote for A (or ...
Ok, to be honest, I don't believe about dragons having a special bladder or organ that stores up gas (especially methane) and having flint-like teeth or whatnot, or even having six limbs. Here's m...
Have a creature from a dream. It's a carbon based humanoid creature partly made of the mineral olivine. Could there be any reason it might contain this mineral? Perhaps a show of health - the more ...
How fast could run a humanoid being, how much damage could resist, how much weight could lift, how strong could hit, under the indicated evolutionary conditions? is there a limit? I have always tho...
Would it be possible to have an organism to be based on alcohol, rather than water? Complexity does not matter, but a complex organism would be favourable. their environment would be in oceans of i...
I made an organism called the Skarlix for a art/xenobiology project called Sagan 4. The Skarlix is a eukaryotic, somewhat amoeba-like organism that "eats" various metal compounds and "breathes" (o...
I've been working on the anatomy of my boron based life using alternative biochemistry. But I've recently came across a problem that I can't solve on my own. In oxygen breathing life on earth, the ...
I'm basically searching for an ATP that can be used to supply cells and also have its energy extracted efficiently into a basic form of explosive material (the stronger the better) without a lot of...
SPOILERS FOR ATTACK ON TITAN, READ AT YOUR OWN RISK... Hardening, or Titan hardening is an ability posessed by certain types of titans in the anime Attack on Titan. Since the setting has rifles ...
Amide bonds are extremely stable and their half-life for hydrolysis in neutral aqueous solution is estimated to be seven years. Amides bind to metal ions through the carbonyl oxygen. Neodymium Mag...
