Cosmic Fireworks: The Largest Black Hole Flare Ever Detected
What was observed A recent study reports the discovery of the most powerful flare ever observed from a supermassive black hole. The event, which occurred when a colossal star wandered too close to the black hole’s gravitational grip, unleashed a brilliant outburst of energy visible across vast cosmic distances. The arrived light is described as…

Chemistry in Pictures: Tiny Ocean Engineers and the Carbon Sequestration Plankton
Introduction: The quiet architects of the carbon cycle In the vast and dynamic marine realm, microscopic algae perform outsized roles. Among them, coccolithophores—tiny, single-celled plankton with plated, spiky exteriors—stand out for their chemistry-rich contributions to Earth’s climate system. These “tiny ocean engineers” pull carbon dioxide from seawater and convert it into calcium carbonate shells, constructing…

Cryo-ET Unveils Kiss-Shrink-Run: A Hybrid Model of Neurotransmitter Release
Cracking the Code of Neurotransmission The brain’s ability to transmit signals rapidly hinges on the precise choreography of synaptic vesicle exocytosis. For decades, scientists debated whether vesicles simply “kiss” the presynaptic membrane and retreat (kiss-and-run) or fully collapse to release their neurotransmitters. A groundbreaking study from the University of Science and Technology of China (USTC),…

Ancient Supernova Imprint in Pacific: Be-10 Spike Evidence
The Be-10 Spike: A Cosmic Fingerprint in Ocean Sediments A remarkable spike in the radioactive isotope beryllium-10 has been detected in sediments from the Pacific Ocean. Beryllium-10 is produced when cosmic rays strike Earth’s atmosphere, leaving a chemical signature that can reveal past astronomical events. The researchers suggest that this spike could point to a…
