Scientists Bust Myth That Our Bodies Have More Bacteria Than Human Cells

Scientists Bust Myth That Our Bodies Have More Bacteria Than Human Cells | Ciencia-Física | Scoop.it
It's often said that the bacteria and other microbes in our body outnumber our own cells by about ten to one. That's a myth that should be forgotten, say researchers in Israel and Canada. The ratio between resident microbes and human cells is more likely to be one-to-one, they calculate.

A 'reference man' (one who is 70 kilograms, 20–30 years old and 1.7 metres tall) contains on average about 30 trillion human cells and 39 trillion bacteria, say Ron Milo and Ron Sender at the Weizmann Institute of Science in Rehovot, Israel, and Shai Fuchs at the Hospital for Sick Children in Toronto, Canada.

The Biggest Obstacle To Mars Colonization May Be Obsolete Humans

The Biggest Obstacle To Mars Colonization May Be Obsolete Humans | Ciencia-Física | Scoop.it
Wherever you go, there you are--even if it happens to be Mars. That's the gist of an essay recently published in the journal Space Policy. Colonizers of Mars may very well escape the grind of terrestrial life, but they likely won't escape the darker sides of their own natures, the authors suggest. This could lead to all sorts of interpersonal strife, legal quandaries, political chaos, and even existential crises, all of which could doom a fledgling colonial community.

The authors, an interdisciplinary team from the University of Information, Technology and Management in Rzeszow, Poland, argue that attention needs to be given to the challenges that will undoubtedly arise in the "new Martian ecological niche."
