Answer	—	A: Do plants need ambient oxygen? Yes. All plants require free oxygen, and any (part of a) plant that is not actively photosynthesising has to obtain its oxygen from its environment. We owe our oxygen supply to the fact that, on average, plants produce more oxygen than they consume. Plants respire in much the same way as other ... (more)	—	about 1 year ago
Answer	—	A: If this earth were cube shaped would it be possible during Magellanic era using a float ship to figure out that the earth is cube shaped? The shape of the Earth is mostly a result of its gravity pulling its mass into the most efficient shape available. The oceans are also pulled towards the centre of mass, and collect on the lowest parts of the surface - covering a huge area to a depth of only a few miles because the planet is so smoo...

Question	—	Could a high-pressure, low oxygen atmosphere reduce fire risk while still being breathable? Years ago I read a letter in a magazine suggesting a method for reducing the fire risk in an enclosed environment such as a space shuttle. The idea was to reduce the oxygen concentration to the point where most common materials won't readily combust, and compensate by increasing the pressure so that... (more)	—	about 2 years ago
Answer	—	A: Digging Depressions in seafloor to create artificial islands in nearby areas Small islands have been built in inland waters since prehistoric times, but using sea floor material to build an offshore island is a much larger project. As Peter Taylor and JBH have pointed out, it has been done) twice off the coast of Dubai. Both those projects have been monitored for erosion an... (more)	—	almost 3 years ago
Answer	—	A: Creatine supplementation as enhancing the natural production of Carnosine and vice versa Possibly, but I think it's unlikely, except indirectly. Exercise increases natural carnosine levels, so someone who both takes extra creatine and uses the energy to increase their exercise level probably would have increased carnosine. I don't know if creatine production is also increased in re... (more)	—	almost 3 years ago
Answer	—	A: Repetitive head-hair removal and lab-grown head-hair planting I assume proper hygiene to prevent post-implant infections, which would otherwise be the biggest risk. Presumably the lab-grown hair needed some hormone(s) to stimulate its growth. There's a chance that this will also increase the risk of a tumour forming in one of the new follicles. If the hormon...

Answer	—	A: Plausibility of "multi-type transmissible animal cell tumor" to form more complex structures. For the cells to act exactly as described would require cooperation between different metastasising cell lines, both during infection and when growing structures in the new host. That implies a kind of control not usually found in a tumour. Even a simple tumour tends to grow into an amorphous mas... (more)	—	over 3 years ago
Answer	—	A: How do you establish identity when people can change their appearance at will? Short, easy-to-read gene tags. Since all modifications are reliably policed, you can require that every modification includes a short, non-coding DNA sequence containing the recipient's legal identity. For good measure they could add the date, the serial number of the clinic, and maybe a regulato... (more)	—	over 3 years ago
