Scientists are investigating a mysterious pulse signal from interstellar object 3I/ATLAS. The signal reportedly follows a Fibonacci pattern and is detected at a frequency linked to interstellar ...

A new publication from Opto-Electronic Sciences; DOI 10.29026/oes.2024.240009 , discusses a smart photonic wristband for pulse wave monitoring. Pulse waves are a prominent component of physiological ...

RF signals historically are measured using spectrum analyzers, at least that was before oscilloscopes offered sufficient bandwidth for those measurements. With oscilloscope bandwidths over 100 GHz, RF ...

A viral claim circulating online suggests that an alleged NASA leak has revealed an interstellar object, identified as ...

The signal, dubbed FRB 20191221A, is the longest-lasting FRB ever discovered and has a clear periodic pattern, repeating every 0.2 seconds for up to three seconds. That’s about 1,000 times longer than ...
