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...

Researchers at the University of Chicago have created new materials that make OLED displays fully stretchable. Their key advance is an aluminium electrode embedded in a gallium–indium alloy, allowing it to “crackle” and self-heal under strain as liquid metal fills emerging gaps. Alongside this, a newly designed stretchy conductive polymer maintains electrical pe...

A new study has identified the primary force behind Venus’s extreme superrotating atmosphere: a once-per-day thermal tide driven by solar heating. Using data from Venus Express and Akatsuki along with circulation models, researchers show that this daily tide transports most of the momentum that accelerates cloud-top winds to speeds over 100 metres per second. The re...

A new study has linked an unexplained LHAASO detection to a pulsar-powered X-ray nebula, confirming it as a rare PeVatron capable of accelerating particles to extreme energies. The discovery is a major step toward solving the long-standing mystery of galactic cosmic rays. Researchers are now combining X-ray, gamma-ray and neutrino observations to trace these powerful ...

China’s Jiangmen Underground Neutrino Observatory has delivered world-class results after only 59 days of data collection, achieving the most precise measurements yet of two major neutrino oscillation parameters. JUNO’s early performance surpasses all previous experiments, confirming a small but intriguing discrepancy between solar and reactor neutrino observation...

NASA’s Perseverance rover may have discovered its first meteorite on Mars, a 31-inch iron-nickel boulder named Phippsaksla found in Jezero Crater. Its pitted, coral-like texture and unusually high metal content resemble meteorites previously identified by Curiosity, Spirit, and Opportunity. Scientists are now analysing the rock’s composition in detail to determine...

A new analysis of NASA’s Fermi telescope data reveals a faint gamma-ray halo around the Milky Way’s core, matching predictions for annihilating dark-matter particles. Researchers say no known astrophysical source fits the signal, raising the possibility of the first direct evidence of dark matter. Experts, however, stress caution and call for verification in other...

A new study suggests that icy moons such as Mimas and Enceladus may host boiling subsurface oceans triggered by thinning ice shells and falling pressure. This low-temperature boiling could still support life beneath the surface. The research also explains geological features on larger icy moons and strengthens their potential as sites for finding extraterrestrial life...

NASA's fractured comet C/2025 K1 (ATLAS) dazzled stargazers on Monday night, offering a rare live view of a cosmic object breaking apart after a close encounter with the Sun. The livestream, organised by the Virtual Telescope Project, began at 10 p.m. EST on November 24 (0300 GMT on November 25) and will broadcast telescopic views of the comet's multiple large fragmen...
