Photonic chip with record-breaking radio frequency dynamic range

Researchers at the University of Twente have developed a revolutionary programmable integrated microwave photonic filter with a record-breaking dynamic range. This represents a major breakthrough in the integration of functionality ...

Quantum leap for research into unhackable communications networks

Scientists at Heriot-Watt University in Edinburgh, Scotland, have published new research into the phenomenon known as quantum entanglement. This is when two particles—such as photons of light—remain connected even when ...

Slight shifts in magnetic field preceded California earthquakes

Researchers studying intermediate to large earthquakes in California have discovered detectable changes in the local magnetic field that occur 2–3 days before an earthquake. In a study now published in Journal of Geophysical ...

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.

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 ...
