Gabriel Sewell, Head of Special Collections, University of St Andrews, added: "We are delighted that we now know when the oldest known periodic table chart came to St Andrews to be used in teaching. To be officially recognised by the Guinness World Records is a wonderful achievement. Thanks ...
Their extreme age always makes the dates suspect, because of possible radiation damage. The radiation damage means the zircons could have been contaminated during their long lifetime. Zircons hold minute amounts of two naturally occurring uranium isotopes— isotopes are atoms of the same element ...
. All of the other elements, like the oxygen we breathe or the sodium in our toothpaste, have been made inside stars or when they die as supernovae. This has led astronomers to search for extremely metal-poor stars: stars with lots of hydrogen, but very little of any other element....
(Isotopes are versions of the same element with different numbers of neutrons in their nuclei.) The findings were published today (April 21) in the Proceedings of the National Academy of Sciences. "This new krypton method is the most precise way of telling us the age of this old ice," ...
Edgar Allan Poe wrote his short story "The Murders in the Rue Morgue" in 1841, in which a Frenchman named C. Auguste Dupin methodically solves the grisly killings of a mother and daughter in a room that was locked from the inside. That plot isn't the only element that sounds like it ...

Isotopes are different versions of the same chemical element that vary in their masses. Different organic substances -- whether in rock, microbe or animal -- contain characteristic ratios of their stable carbon isotopes. Using SIMS, Valley's team was able to tease apart the carbon-12 from the...
