A: How can a terrorist group link a biological plague to a specific genetic signature? Genetic genealogy testing can already identify people as belonging to various minority ethnic groups. Some are better than others. For example, Ashkenazi (generally, Jews with Eastern and Central European ancestry within the last couple hundred years) DNA markers are fairly robust and show up as ex... (more) |

A: Realistic Demonic Possession Follow the lead of many many Science Fiction movies, TV shows, and books that create aliens or fantasy creatures as real beings and give them the ability to "possess" human beings and control their minds or bodies. "These very real beings are what humans thought were demons" is a pretty common trope... (more) |

A: How can someone be immortal and still age? Eternal youth and immortality are two completely different superpowers. Eternal youth bestowed at the moment of birth is a curse. While the person could learn things, the lack of motor control and the lack of pruning in the brain would be permanent (unless you change the specifics of the curse). E... (more) |

A: How to explain one side of Super Earth is smoother than the other side? The planet orbits its star normally but it has a moon whose orbit is such that the moon is visible from one side of the planet but not the other. The planet's day is long enough that the moon does not have to have a particularly fast orbit in order to match the planet's spin. The moon has been slow... (more) |

A: Anal Retentiveness in a tribal nomadic society - why would it be advantageous? Just tweak their physiology so something about doing it on the journey makes things dangerous. Or it takes too much time. Or maybe it's because of predators tracking them. Things are safer in the oasis. Or it's a hygiene issue. They have to wait until they're someplace with more water. This c... (more) |

A: How long could humans survive on my planet? Start off with a safe village/colony. People living in the parts of rural Africa with wild lions will surround their villages with thorn bushes the lions don't cross (for example, acacia thorns in East Africa). This doesn't eliminate attacks but it greatly reduces them. Or a modern version. O... (more) |

A: Is it theoretically possible for the human body to not defecate? The real question is, for how long? Short-term: Sure. A few days or even weeks is doable and shouldn't cause any lasting harm. Long-term: Only if you have to. There are consequences to your health. A friend of mine lived for years with nothing but a central line and drinking water. She had profo... (more) |

A: Life in the Northern Hemisphere if Beringia Never Drowned The best choice isn't on your list: Mastodons vs Woolley Mammoths. Both, unlike their Elephant cousins, do well in the cold. They represent two distinct species of the Proboscidean family. From your list though, I'm gonna say.. Dogs. Wolves are already native to the American side of Beringia. ... (more) |

A: Everyday tasks on a space ship ...once they reach a planet, they do research. Nope. They're doing research all the time. That's their full-time employment.

A: Why bother programming facial expressions for artificial intelligence if humans are bad at recognising them? Humans are actually very good at recognizing facial expressions and body language. While it's true that large numbers of people are terrible at it, it's only in comparison to the average human. Assuming unimpaired vision and intelligence, humans use facial expressions to tell who among a group of p... (more) |

A: Ideal Time Period for a Global Pandemic If you want to wipe out 80% of the world's population with a disease that has an 80% fatality rate, then every person on the planet (or close enough to round up to 100%) has to catch it within the designated time period. Normally I'd agree with others who have written about the horrific flu epidemic... (more) |

A: Proper technique for eating grass? Cooking Cooking plant materials takes care of the problem of the grasses being too hard on our teeth or digestive systems. In many cases, breaking down the fibers and so forth will release more calories and micronutrients. Some of this can also be done with fermentation. Once a species has the ab... (more) |

A: Life in permanent shadow Some plants and animals would focus on the borderlands. While regular shade could exist anywhere, mountains and other large geology would give the deepest shade, enough to change the climate.

A: Could DNA Survive in Outer Space? Blood is not the best substance here. Most of the tests for genetic genealogy and genetic medical testing use saliva or epithelial inner cheek cells.

A: How can I keep an area next to a mountain range from being a desert? So you want a less eroded version of the Appalachian Mountains? If rain (and humidity) come from the ocean, mountains will not stop areas between the ocean and the mountains from getting that rain.

A: Locking an old spaceship from the outside? Get a lockbox. These things are sturdy and not something you could break open with a hammer. You have better tech than modern-day Earth though, so you can use even stronger materials. Something that a circular saw couldn't cut.

A: Best place on an humanoid body to develop biological radio? I would make it part of the cochlea. Either as a separate organ or as an enhancement of the cochlea. The nerves, ducts, and other parts of the cochlea are very small and delicate and you wouldn't want to mess with them. But if you replaced this organ with one that allowed the person to continue ...

A: What are the architectural considerations when an underwater species builds a city? Marine mammals can stay underwater for 10 mins to 2 hours tops. This is fantastic compared to humans, but not enough to justify an underwater city. Underwater storage units maybe. Your species is a cross between elephant seals and orcas. The former holds the underwater record: 2 hours (though the... (more) |

A: How might a purely mechanical 'voice' function? BACKGROUND (setting the context for my answer): I actually used to be a researcher in a university lab that created the software for voice synthesizers back in the 1980's.

A: How long can a preserved human body last before turning to dust? There are a variety of preservation techniques with different results.

A: how can I ensure that the amount of jing that a person has at birth is completely random? So is this real-life jing (also), part of Traditional Chinese Medicine and related disciplines, with maybe some supernatural/fantasy twists? Or some made-up thing that is similar and has the same name? The real-life kind is inherited, in a way. Chinese and Western terms often do not overlap well... (more) |

A: How can a bird survive self ignition? The birds have two layers of feathers. The layer closest to the skin is fireproof. Not 100% because that would be extremely difficult, but enough to last 1-2 minutes. They will not ignite in that time and they provide some insulation from the worst of the heat. The layer over the insulating lay... (more) |

A: How would constant rhythmic tsunamis affect the coast lines of the Atlantic Ocean? Really big tides and really low tides. With the average exactly where it is right now. There might be multiple high and low tides (vs the two a day of each that we have now).

A: A parasite that infects humans who are over the age of 25 The parasite lies dorment in wisdom teeth. Wisdom teeth usually emerge sometime between the ages of 17 and 25.

A: Natural uncovering of desert ruins I can't do better than Wilik's answer, but I'd like to add to it. The land flooded and the sea built up with silt and eventually dried completely, leaving only desert. As it dried, it left a crust perhaps a foot or two thick (30-60 cm). I'm thinking limestone or something similar. This crust isn'... (more) |

A: How might a naturally-occuring geographical barrier between two areas *suddenly* become permeable so that a few people can cross it? Drought. Basing this on your explanatory comment: Most roads have been destroyed (mudslides, earthquakes, floods), cars are a thing of the past, water is scarce. Drought will lower the level of lakes and rivers. While the levels won't change super quickly, they still have tides (larger lak... (more) |

A: How advanced would human civilization get if it was destroyed by insects every 20 years? Presumably the insects swarm, gorge, breed, then either die or hibernate. Then come out in force 20 years later after the eggs have hatched and the larvae mature into adults who can fly and who need human blood in order to support breeding. Humans have 20 years to find and kill the eggs or to kil... (more) |

A: How could a species that breathes through its skin develop spoken language? In our human world, languages can be signed via movement of the arms, hands, and fingers (with the latter two communicating the most information) or they can be spoken with air moving up from the lungs, over the vocal cords, and then shaped by the vocal tract. Spoken language can be done without air... (more) |
