What does this have to do with steel?
Did you know that all the nuclear bombs we exploded in the '40s-50s-60s have permanently contaminated all the steel the world has produced since then? All steel in the world is divided into two categories: pre-1945 non-contaminated steel, and post-1945 contaminated steel.
How?
What does this have to do with steel?
So we need pre-1945 steel
We go, find pre-World-War-II sunken shipwrecks, and then salvage the steel (and lead) from those to build our instruments which need heavy radiation shielding.

Does that mean the entire population of earth which is breathing this air for atmospheric oxygen is also inhaling Conalt-60?

The worst treatment was kept for the monkeys. The macaques breed of monkeys are small, relatively light primates, which are often used for animal experiments at LPT. \u2018They are kept in cramped conditions in small cages. https://t.co/6D0yisjd9B

In some cases, almost 100% of the light energy can be converted to the second harmonic frequency. These cases typically involve intense pulsed laser beams passing through large crystals, and careful alignment to obtain phase matching.

Viruses and other pathogens are often studied as stand-alone entities, despite that, in nature, they mostly live in multispecies associations called biofilms—both externally and within the host.

Microorganisms in biofilms are enclosed by an extracellular matrix that confers protection and improves survival. Previous studies have shown that viruses can secondarily colonize preexisting biofilms, and viral biofilms have also been described.

...we raise the perspective that CoVs can persistently infect bats due to their association with biofilm structures. This phenomenon potentially provides an optimal environment for nonpathogenic & well-adapted viruses to interact with the host, as well as for viral recombination.

Biofilms can also enhance virion viability in extracellular environments, such as on fomites and in aquatic sediments, allowing viral persistence and dissemination.

He's STILL in charge of the Mueller investigation.
He's STILL refusing to hand over the McCabe memos.
He's STILL holding up the declassification of the #SpyGate documents & their release to the public.
I love a good cover story.......
The guy had a face-to-face with El Grande Trumpo himself on Air Force One just 2 days ago. Inside just about the most secure SCIF in the world.
And Trump came out of AF1 and gave ol' Rod a big thumbs up!
And so we're right back to 'that dirty rat Rosenstein!' 2 days later.
At this point it's clear some members of Congress are either in on this and helping the cover story or they haven't got a clue and are out in the cold.
Note the conflicting stories about 'Rosenstein cancelled meeting with Congress on Oct 11!"
First, rumors surfaced of a scheduled meeting on Oct. 11 between Rosenstein & members of Congress, and Rosenstein just cancelled it.
Rep. Andy Biggs and Rep. Matt Gaetz say DAG Rod Rosenstein cancelled an Oct. 11 appearance before the judiciary and oversight committees. They are now calling for a subpoena. pic.twitter.com/TknVHKjXtd
