The atmosphere is a major part of the water cycle. There is much untapped potential in the use of water vapor isotopic measurements and modeling to learn about current processes in the atmosphere, as well as assessing past atmospheric circulation patterns and storm paths. Read more.
Time is “what we read from a clock located at the same point at which an event occurs,” said Albert Einstein. American theoretical physicist John A. Wheeler defined it as “a phenomenon which prevents all things from happening simultaneously.”
While time remains an eternal mystery for philosophers and scientists, the language of art tries to represent it. German artist Kerstin Ergenzinger, fellow of the graduate school at the Berlin Center for Advanced Studies in Arts and Sciences, started cooperation with a team of physicists who are trying to create a highly precise clock using the nucleus of the Thorium-229 atom.

Because of its high nutritional value and distinctive flavor, natural honey is a premium product with a price tag significantly higher than that of other sweeteners. As a result, honey is often the target of adulteration using low-cost invert sugar syrups. This article looks at two analytical approaches based on isotope fingerprint analysis using isotope ratio mass spectrometry (IRMS) that can be used to detect honey adulteration and safeguard product integrity.

A new version of a European "road map" lays out the technological hurdles to be overcome if the processes powering the Sun are to be harnessed on Earth. The road map has been drawn up by scientists and engineers at EUROfusion. This is a consortium of European laboratories and universities that funds research on fusion energy. Read more.
Newfoundland’s and Labrador’s ties to the Emerald Isle go back centuries and continue today in song, story and lifestyle.
Parts of Ireland and Newfoundland were once connected and part of the supercontinent Pangea; the land forms separated from one another around 180 million years ago when Pangea started to break apart and form the modern Atlantic Ocean.
Specific pieces of rocks often have distinctive geochemical and isotopic signatures, particularly so for the isotopes of lead, which are often distinctive for different parts of the mountain chain. Read more.
