Great statement from Neil DeGrasse Tyson on “what is the most astounding fact you can share with us about the universe.”
“The atoms that comprise life on earth, the atoms that make up the human body, are traceable to the crucibles that cooked light elements into heavy elements in their core under extreme temperatures and pressures. These stars, the high mass ones among them, went unstable in their later years. They collapsed and then exploded scattering their enriched guts across the galaxy. Guts made of carbon, nitrogen, oxygen, and all the fundamental ingredients of life itself. These ingredients become part of gas clouds that condense, collapse, form the next generation of solar systems: stars with orbiting planets. And those planets now have the ingredients for life itself. So when I look up at the night sky and I know that, yes we are part of this universe, we are in this universe, but perhaps more important than both of those facts, is that the universe is in us… my atoms came from those stars….”
I think this might well be my thought on the most astounding fact also. Ever since I learned the atoms we are made of were created inside stars it has never ceased to amaze me.
Neil DeGrasse Tyson is amazing. I would edit his statement a bit myself, though, to make it:
“The most astounding fact is that the atoms that comprise life on earth, the atoms that make up the human body, were created in the crucible of stars that cooked light elements into heavy elements. Those stars went unstable, in their later years: they collapsed and then explored scattering their enriched cores across the galaxy. Those stars made the carbon, nitrogen, oxygen, and all the fundamental ingredients of life itself. Those ingredients became part of gas clouds that condensed to form the next generation of solar systems: stars with orbiting planets. And those planets have the ingredients for life. So when I look up at the night sky, I know that my atoms came from the predecessors of the stars I see.”

Our Dangerous Antibiotic Practices Carry Great Risks
Posted on July 12, 2012 Comments (4)
Our continued poor antibiotics practices increase the risk of many deaths. We are very poor at reacting to bad practices that will kill many people in the future. If those increased deaths happened today it is much more likely we would act. But as it is we are condemning many to have greatly increased odds of dying from bacterial causes that could be prevented if we were more sensible.
Resistance to antibiotics is becoming a crisis
…
evidence is mounting that antibiotics are losing efficacy. Through the relentless process of evolution, pathogens are evading the drugs, a problem known broadly as antimicrobial resistance.
…
Europe has launched a $741 million, seven-year, public-private collaborative research effort to accelerate drug development.
Seeking new antibiotics is wise but the commentary completely ignores our bad practices that are causing the problem to be much worse than it would be if we acted as though bad practices that will lead to many deaths should be avoided.

Obviously bacteria evolve to survive the counter measures we currently have. The foolish practices of promoting ignorance of evolution leads to a society where the consequences of actions, and the presence of evolution, lead to bad consequences. We find ourselves in that society.
