Researchers have developed a new technology that can shape the spectrum of light emitted from a laser frequency comb across ...

The ternary composite (SiC/CoSi/CeSi) achieves an impressive RL value of -66.48 dB at 3.65 GHz, while maintaining 94.5% of its absorption performance (-63.34 dB at 4.31 GHz) even after oxidation at ...

Quasiperiodic (QP) very low frequency (VLF) emissions are intermittent bursts of electromagnetic energy, observed in the frequency range of approximately 3–30 kHz, that recur at quasi-regular ...

An asteroid is the most likely reason the dinosaurs went extinct—but could something similar happen to us? A new study has compared the likelihood of a devastating asteroid impact to other causes of ...
