I am constantly amazed at how pathologizing variable phenomena is usually a human social agent. Consider the XY fertile Akodon females who go roaming around in South America. No other rodents seem to have told these fertile XY females that they have a  disorder of sex development (DSD). That will undoubtedly be left to some of the "powers that be" of the human species. Shall I say rats? Or shall I say of mice and men?

Judging by recent polls, you would think that the environment is not much of a concern to Americans. And You would also be wrong, say researchers from Standford University. When pollsters ask Americans to name the most important problem facing the country, the environment is rarely mentioned. But these results change drastically if pollsters replace "country" with "world" in the question, the researchers say.

"For years, the wording used in traditional surveys has systematically underestimated the priority that the public has placed on global warming and the environment," said Jon Krosnick, a professor of communication and of political science at Stanford. "To fully understand public concern about these issues, traditional surveys should be asking a different question."

By analyzing tiny variations in the isotopic composition of silver in meteorites and Earth rocks, scientists are putting together a timetable of how our planet was assembled 4.5 billion years ago. The new study, published in Science, indicates that water and other key volatiles may have been present in at least some of Earth's original building blocks, rather than acquired later from comets, as some scientists have suggested.

Compared to the Solar System as a whole, Earth is depleted in volatile elements, such as hydrogen, carbon, and nitrogen, which likely never condensed on planets formed in the inner, hotter, part of the Solar System. Earth is also depleted in moderately volatile elements, such as silver.
