How algae use a 'sulfate trap' to selectively biomineralize strontium
(PhysOrg.com) -- In any kind of nuclear reactor, there is a small amount of the radioactive isotope strontium-90 that is formed as part of the regular fission process. In fact, fission products such as strontium-90 ...

How to discover a new element
(PhysOrg.com) -- It is not the same as it used to be, the element finding business. We have discovered and named all the elements from hydrogen (element 1) up to element 112 (copernicium)[1], and last week ...

Pa. allows dumping of tainted waters from gas boom
(AP) -- The natural gas boom gripping parts of the U.S. has a nasty byproduct: wastewater so salty, and so polluted with metals like barium and strontium, that most states require drillers to get rid of the ...
