Capturing a cosmogenic isotope to determine the age of artifacts
You may probably wonder how archaeologists determine the age of ancient artifacts or how long a piece of rock exists above the surface. Isotopic dating can tell the age covering hundreds of thousands of years. For instance, common carbon isotope 14C.....»»
Machine learning solves the who"s who problem in NMR spectra of organic crystals
Solid-state nuclear magnetic resonance (NMR) spectroscopy—a technique that measures the frequencies emitted by the nuclei of some atoms exposed to radio waves in a strong magnetic field—can be used to determine chemical and 3D structures as well.....»»

Open-sourcing of protein-structure software is already paying off
The big trade-off is between computational intensity and the size of the complex. Enlarge (credit: Humphreys et. al.) It is now relatively trivial to determine the order of amino acids in a protein. Figuring out how that order.....»»
Capturing a true picture of wolves in Yellowstone: Reevaluating aspen recovery
It's an environmental success story that feels like a parable—the reintroduction of wolves in Yellowstone National Park in the mid-1990s triggered a cascade of effects that ultimately restored the ecosystem, including the recovery of aspen trees. B.....»»
New tests track sources of lead contamination in urban soils and assess its risks
Scientists have developed a suite of isotope-based tests that can be used to identify the origin of lead contamination in urban soils and assess the risk it poses to children who inhale or ingest contaminated dirt or dust. The tests can distinguish b.....»»
