“Low-background metals are valuable because they carry particularly low levels of radiation. Used as shielding in advanced particle physics projects and medical science devices like X-ray chambers, these metals won’t interfere with specialized, highly radiation-sensitive tools.”
2/“Most steel is made by blowing air or pure O2 into molten pig iron to remove impurities & make it stronger. Since start of atmospheric nuclear tests, all air-even purified O2, contains elevated levels of isotopes like cobalt-60,most new steel is infused w/radioactive particles.
2/“By drilling into sediment cores 100s of feet beneath Antarctica’s sea floor, scientists discovered that during previous periods of global warming—3M & 15M yrs ago—loose sediment layers formed & slipped, sending massive tsunami waves to the shores of S America, NZ & SE Asia.”
3/“Weak layers beneath 3 submarine landslides, consist of…oozes & glaciomarine diamicts. The lithological differences, from glacial to interglacial variations in biological productivity, ice proximity & circulation, caused changes in deposition preconditioning slope failure.”
2/aerosol particles in the past 10-20 years, as new regulations limited emissions from the biggest sources, including the burning of coal & heavy ship fuels.”
@DanCady@Msmariablack It does‼️ I’m listening to #BREATHLESS for the 3rd time & got a physical copy. It’s excellent science & narrative on SARSCoV2. Author @DavidQuammen interviewed ~ 100 researchers in all science fields relating to virus origins, controversies, virology, evolutionary molecular 1/
“We have a great deal of information, but not enough knowledge. #Breathless explains the basic science of the coronavirus in a way we can understand.
It shows how scientists all over the world mobilized and communicated to learn MORE
@DanCady@Msmariablack@DavidQuammen 3/ how the virus works, making it possible to develop vaccines faster than has ever been done before. Breathless is a portrait of science—and scientists—in action during a time of crisis.

2/for a disease outbreak to reach anywhere in the world because of international travel & trade.”
The analysis is based on an examination of 95 spillovers in the past 2 decades of viruses found in bats, including Ebola, SARS, Marburg & Nipah. The news agency identified MORE
