Managing long-term effects of low gravity on human health [8] would therefore be a significant issue for long-term occupation of Titan, more so than on Mars. These effects are still an active field of study. They can include symptoms such as loss of bone density, loss of muscle density, and a weakened immune system.
Tin has no known natural biological role in living organisms. It is not easily absorbed by animals including humans. The low toxicity is relevant to the widespread use of tin in dinnerware and canned food. [1] Nausea, vomiting and diarrhea have been reported after ingesting canned food containing 200 mg/kg of tin.

Odor threshold value can be expressed as a concentration in water or concentration in air. Two major types of flavor thresholds can be distinguished: the absolute and the difference threshold. The odor detection threshold and the odor recognition threshold are absolute thresholds; the first is the minimum concentration at which an odor can be ...
See, these scientists had a theory: it’s not just humans that bed bugs are attracted to, it’s the smell of a human. Bed bugs, along with mosquitoes and ticks and plenty of other blood-sucking ...
A new study has shown that exposure to a fishy smell can make people more suspicious, raising their level of critical thinking skills.
The sense of smell can induce pleasure or subconsciously warn of danger, which may, for example, help to locate mates, find food, or detect predators. Humans have an unusually good sense of smell considering they have only 350 functional olfactory receptor genes compared to the 1,300 found in mice, for example.
Losing or not having your sense of smell may be linked to changes in breathing that could lead to depression, social isolation or other mental health problems, a new study suggests.
Due to the impact smell has on the human brain and the reception of different people, it can impact whether or not an individual accepts another individual. Bad smells can drive people away due to the harsh nature of the odors, whereas nice smelling fragrances can communicate positively. [ 10 ]
