Researchers track groundwater discharges into salt ponds

The movement of groundwater in aquifers deep beneath the surface often carries with it a variety of contaminants that can be traced to leaking septic systems, damaged underground infrastructure, excessive fertilizer use and ...

Probing the origin of the mantle's chemically distinct 'scars'

The composition of Earth's mantle was more shaped by interactions with the oceanic crust than previously thought, according to work from Carnegie's Jonathan Tucker and Peter van Keken along with colleagues from Oxford that ...

Mapping the 3-D geometry of SARS-CoV-2's genome

The novel coronavirus uses structures within its RNA to infect cells. Scientists have now identified these configurations, generating the most comprehensive atlas to date of SARS-CoV-2's genome.

Measuring adhesion and friction of polymer nanofibers

Using a device small enough to fit on the head of a pin, researchers at the University of Illinois at Urbana-Champaign gained new knowledge about the properties of polymer fibers at the nanoscale—knowledge that can inform ...

Nanomaterials— short polymers, big impact

Oak Ridge National Laboratory scientists have discovered a cost-effective way to significantly improve the mechanical performance of common polymer nanocomposite materials. The discovery could lead to stronger, more durable ...

Record-setting rain and heat? This is the new normal

I'm the director of the North Carolina Climate Office, which is the go-to source for expertise in North Carolina's climate. But if you call me to ask if there's a downpour on the way, I probably won't know the answer off ...
