Internet cable reveals the source of underwater vibrations

Scientists have harnessed Internet-transmitting fiber-optic cables to overcome a long-standing geophysical challenge: identifying where seismic noise in the ocean originates. Tiny vibrations of Earth called microseisms are ...

Quantum light source advances bio-imaging clarity

Texas A&M University researchers accomplished what was once considered impossible—they created a device capable of squeezing the quantum fluctuations of light down to a directed path and used it to enhance contrast imaging.

New atlas of bird migration shows extraordinary journeys

A bay-breasted warbler weighs about the same as four pennies, but twice a year makes an extraordinary journey. The tiny songbird flies nearly 4,000 miles (6,437 kilometers) between Canada's spruce forests and its wintering ...

Optimizing competing instrument needs with an objective metric

Designing instruments for spacecraft missions is an exercise in managing trade-offs. With severe restrictions on power, mass, and volume, space-based instruments are often compromised in ways an equivalent laboratory instrument ...

Using seismology for groundwater management

As climate change increases the number of extreme weather events, such as megadroughts, groundwater management is key for sustaining water supply. But current groundwater monitoring tools are either costly or insufficient ...
