A study by Australian biologists and zoos, showed that since ancient times, penis size is important for women. The study published in the National Academy of Sciences showed that women find men with large penis more attractive, combined with a number of factors determinants such as body type and height.

We are sure you would love to know more about these peculiar beings... Art, medicine and biotechnology Patricia Piccinini poses a challenge to us.What if there was a day when it was licit genetic manipulation ? What if we could create new creatures halfway between the human and the animal? These hybrids that she herself brings us in such a magnificent way, are a metaphor for this idea.An invitation to reflection. We just have to think about a ...

Human beings autotrophs? Live without eating or drinking?

It means that an organism is capable of producing its own food from inorganic substances.Plants, for example, use carbon dioxide from the sun to produce nutrients, which also take advantage of soil and water. The heterotrophs , on the contrary, are the beings that feed on organic substances produced by others, like the rest of the living beings, including us. Therefore, autotrophic nutrition... ...is the ability of some organisms to synthesize the essential elements for their metabolism from inorganic substances, so that in order to stay they do not need other living beings .It is very good in plants or in some bacteria, but is it possible that humans get to that? Is it possible that we can live without water or food? Some notable cases of breathing? Science tells us that it is literally impossible to live without drinking or eat anything.We need the nutrients found in other living things, such as vegetables and animals.Human...
