Can quantum particles mimic gravitational waves?
When two black holes collide, space and time shake and energy spreads out like ripples in a pond. These gravitational waves, predicted by Einstein in 1916, were observed for the first time by the Laser Interferometer Gravitational-Wave Observatory (L.....»»

Experiment uses quantum techniques to stimulate photons, enhancing search for dark matter
Scientists cannot observe dark matter directly, so to "see" it, they look for signals that it has interacted with other matter by creating a visible photon. However, signals from dark matter are incredibly weak. If scientists can make a particle dete.....»»
NASA, JAXA bounce laser beam between moon"s surface and lunar orbit
NASA's LRO (Lunar Reconnaissance Orbiter) has twice transmitted a laser pulse to a cookie-sized retroreflector aboard JAXA's (Japan Aerospace Exploration Agency) SLIM lander on the moon and received a return signal......»»
Unlocking carbon"s potential: CRISPR boosts lignocellulose absorption
Lignocellulosic biomass, such as paper mulberry, holds promise for sustainable material production due to its cost-effectiveness and renewability. However, optimizing lignin composition remains challenging due to its complex structure and varied comp.....»»
Astronomers find first emission spectra in brightest GRB of all time
