Developing a flat soliton microcomb source

Optical chip-related technology is the inevitable path to retain the validity of Moore's Law, which has become the consensus of academia and industry; it can effectively solve the speed and power consumption problems of electronic ...

Scientists measure the distance to stars by their music

A team of astronomers has used asteroseismology, or the study of stellar oscillations, to accurately measure the distance of stars from the Earth. Their research examined thousands of stars and checked the measurements taken ...

Two largest marsquakes to date recorded from planet's far side

The seismometer placed on Mars by NASA's InSight lander has recorded its two largest seismic events to date: a magnitude 4.2 and a magnitude 4.1 marsquake. The pair are the first recorded events to occur on the planet's far ...

Creating frequency combs in microresonators

For the first time, scientists were able to create ultrashort dark and bright light pulses that are linked together in tiny glass rings called microresonators. Each of the flashes consist of many different, precisely defined ...

Molecular device turns infrared into visible light

Light is an electromagnetic wave: It consists of oscillating electric and magnetic fields propagating through space. Every wave is characterized by its frequency, which refers to the number of oscillations per second, measured ...

SARS-CoV-2: Achilles' heel of viral RNA

When SARS-CoV-2 infects a cell, it introduces its RNA into it and re-programs it in such a way that the cell first produces viral proteins and then whole viral particles. In the search for active substances against SARS-CoV-2, ...
