Using today's (real) genetic engineering methods, would it be possible to engineer a horse with a single spiral horn? Maybe rub a horse on a narwhal? I know mythical Unicorns have other "powers",...
I am wondering what are some of the major concerns/designs an intelligent flying species would have in designing a starship? Generally we consider space to be a premium and crew living space is al...
Lets say you have a small group of space colonists. They were screened for sickness, viral and bacterial, as thoroughly as we knew how before being sent off to the colony and all were found health...
It is 1970. Planet Earth is uninhabitable - the Cold War got very hot. The Earth's entire population is floating through space in giant transport ships. They've found another habitable(ish) world....
Melanin is what causes the color to appear in the skin, hair and eyes. But in humans there seems to be a limit to this. For example human hair can be orange(gingers) but not green or blue. iris's c...
In mammals - and that includes us humans - the lungs make up 7% of the total body volume. This allows us to inhale oxygen and exhale carbon dioxide, thanks to the pulmonary alveoli. But bird lungs...
The Chirr are a race of space-faring aliens that look vaguely like rat-sized ants. They've got powerful mandibles and small, fairly dexterous hand-like claws, though their chitinous nature makes de...
All A.I. comes with a built-in safety mechanism that prevent their kind from ever doing harm to a human or humanity, it is the last straw should they pose any real threat to our safety. A century ...
An alien life form is found that has a pattern of stripes on its back. The pattern is black, red, yellow, green, cyan, blue, and magenta, black, and so on. It is found that for each series of dif...
Hey guys so I've posted on this site before and I've finally made an account so I'd like to ask again about mine and my friend's webcomic WIP. Biology wise, I've made three main groups of animals, ...
Another question for my comic: my friend has made a demand that I give one of her characters a flying mount, preferably griffin-like. I have some designs but I want them to be plausible: How bulk...
Tidally locking a rock or metal moon isn't too hard and the understanding of how a solid moon behaves while tidally locked is relatively well understood. However, can a water moon be tidally locked...
Like this question I'm wondering about design considerations for an intelligent aquatic species that wants to travel into space. Would they have to try and create special body suits to keep moistur...
In many famous alien species you see that the iris is so large that it almost appears that it replaces the sclera. What evolutionary history would support the irises growing to that size. The only...
I seek a realistic method, either by genetic change or other scientific method that doesn't require magic or future tech, to obtain naturally occuring two tone hair for a race of humanoids. My id...
Let's say that in my planetary system there is a gas giant around the size and distance from the Sun as Jupiter. I need the planet to be similar enough to earth to be able to be inhabited natural b...
The (female) human body is pushing the anatomic extremes to support, later bear and nurse a baby while maintaining upright posture and bipedal walk. I cannot see a way to realistically make pregnan...
I have an organization that I want to have some kind of HQ without being in a country. I was reminded of Sealand (Thanks Joel), those platforms off the coast of the UK. I want something similar, ...
I'm working on creating a world with three moons, all with different sizes and different orbits. I'm wondering what effects this would have. How would the tides be affected, obviously, but also wou...
In popular science fiction, we see habitable Earth-like planets with visible, Saturn-like rings. In reality, such rings exist only on gas giants, a category where we can find Saturn. Is it really...
I've created a world where science has developed a new species of bird (kind of a bird, it's like a Basset Hound with wings) to be used purely as a utilitarian species. (Carrying of small loads, me...
What would the implications be for a humanoid species to excrete only gaseous waste from themselves instead of solid or liquid waste? Public bathroom facilities would not be needed, but how would ...
I'm creating a bronze age setting and one of the civilizations gets their powers from a river whose irrigation produces a vast food supply. So, I decided to figure out where the most powerful city ...
I have to make a map for two planets. For booth two I already have an idea about what they look like, but I don't know how to draw them. They don't need to be really clear, however they should make...
It's now the late 23rd century and there are now hundreds of space stations, orbiting approximately at the height of the (now deceased) ISS, give or take a few kilometers. Lately, the International...
