A new study proposes detecting gravitational-wave “beats” using pulsar timing. Researchers from Hirosaki University suggest that interference between waves from supermassive black hole binaries could appear as periodic variations in pulsar signals. The method may help distinguish individual sources from a diffuse gravitational-wave background in upcoming observati…

New research from RMIT University shows that spent coffee grounds can be transformed into biochar and used to replace a portion of sand in concrete, creating a stronger and more sustainable building material. Heating coffee waste at around 350°C without oxygen produces a fine biochar that boosts concrete’s 28-day strength by roughly 30% when used at 15% substitutio…

NASA’s Fermi Gamma-ray Space Telescope has detected a faint halo of high-energy gamma rays around the Milky Way’s centre—matching predictions for dark-matter annihilation. The finding, reported by Professor Tomonori Totani, could represent the first direct glimpse of dark matter, but scientists caution that alternative explanations remain and independent confirm…
