So if we’re right, each former human is now essentially a radio transmitter and receiver. One plurb sends out a signal that ...

Sum-frequency generation (SFG) is a powerful vibrational spectroscopy that can selectively probe molecular structures at ...

After the Big Bang, the Universe entered a long, dark period before the first stars formed. During this era, hydrogen emitted a faint radio signal that still echoes today. New simulations show this ...

Abstract: Simultaneous phases detection in multi-wavelength interferometry (MWLI) is essential for high-accuracy dynamic absolute distance measurement in high-end equipment manufacturing. To address ...

Abstract: We experimentally demonstrate, for the first time, the co-wavelength-channel integration of ultra-low-frequency distributed-acoustic-sensing and high-capacity communication over a 38-km ...

A cornerstone of the most effective facials, high-frequency technology quells acne, inflammation, and redness in a quick, ...

Radio telescopes are instruments that capture faint radio signals from space and convert them into images of celestial bodies ...

Many projects on these pages do clever things with video. Whether it’s digital or analogue, it’s certain our community can push a humble microcontroller to the limit of its capability.

A new study showcases how brain waves known as alpha oscillations help us distinguish between ourselves and the outside world ...
