Researchers identify African dust by measuring isotopes

Every summer, weather forecasters blast news about African dust plumes crossing the southern United States. And to most people, it's just dust, but to researchers at Texas A&M University, it's much more.

Old genes keep sea anemones forever young

The genetic fingerprint of the sea anemone Nematostella vectensis shows that the members of this evolutionarily very old animal phylum use the same gene cascades for the differentiation of neuronal cell types as more complex ...

How old is that fingerprint?

Forensic dramas on TV make it seem easy to determine when fingerprints were left at the scene of a crime. In reality, the oils in fingerprints degrade over time, and it's difficult to figure out their age. Now, researchers ...

Deformation fingerprints will help researchers identify, design better metallic materials

Engineers can now capture and predict the strength of metallic materials subjected to cycling loading, or fatigue strength, in a matter of hours—not the months or years it takes using current methods.
