POSTECH and University of Montpellier researchers demonstrate wafer-scale AA-stacked hexagonal boron nitride (hBN) growth.

Scientists have shown for the first time that Antarctic krill show a stereotypical reaction in the presence of guano from Adélie penguins: they swim faster and make more turns over greater angles. It is unknown to what kind of water-borne chemical cues they respond, but the authors speculate that this behavior might be a universal escape response to the excreta of predators, irrespective of species.

A newly published study in the Journal of Cosmology and Astroparticle Physics JCAP has not detected any signals attributable to quantum gravity effects in the neutrinos observed by the underwater detector KM3NeT/ORCA in the Mediterranean Sea. However, the result is significant because it establishes new experimental limits on quantum decoherence in neutrino oscillations—a phenomenon that, if detected, could indicate the existence of quantum gravity effects, a crucial piece in our understanding of the Universe and its fundamental laws. The identified limits further contribute to the ongoing effort to bridge quantum mechanics and general relativity.

A recent study has unveiled a novel strategy to boost the efficiency of solar photovoltaic (PV) systems in agriculture, offering a solution to longstanding challenges. By integrating the Greylag Goose Optimization (GGO) algorithm with a seven-level inverter, the research team has achieved impressive advancements in maximum power point tracking (MPPT) and significantly reduced total harmonic distortion (THD). This innovation ensures more reliable and stable power for agricultural machinery, while also cutting operational costs and extending the lifespan of equipment.
