The covalent chemistry of reactants tethered within a single protein pore can be monitored by observing the time-dependence of ionic current flow through the pore, which responds to bond making and ...

Scientists have long used isotopes in water molecules to study where atmospheric moisture comes ...

Quantum technologies, computers or other devices that operate leveraging quantum mechanical effects, rely on the precise ...

With the new grant, the Stable Isotope Lab will acquire a cutting-edge instrument called an isotope-ratio-monitoring mass spectrometer (IRMS). A major grant from the National Science Foundation (NSF) ...

Where there’s electricity, there’s usually heat – and that’s a major hurdle for shrinking electronic devices. Scientists have now found that nanowires made of a certain isotope of silicon can conduct ...

This policy deals with radioisotopes. For stable isotopes, see Stable Isotopes on SIO Ships. The SIO Isotope Use Committee (the IUC) reviews all experiments involving natural isotopes and ...

The nucleus of each atom contains protons and neutrons. While the number of protons defines the element (e.g., hydrogen, carbon, etc.) and the sum of the protons and neutrons gives the atomic mass, ...

Real satellite water vapor isotope data were assimilated in a general circulation model to determine whether including these data could improve forecast accuracy at both the global and local scales.

Early warning of climate risk is the gold standard that scientists, managers and governments are working towards. Doing this requires a detailed understanding of not just the amount of precipitation ...

That natural, bee-produced sweetener you stir into your tea and lavish on your toast may be laced with cesium-137. It’s a radioactive isotope, Jim Kaste explains, a relic of the atom bomb tests of the ...
