Astronomers are rethinking one of cosmology's biggest mysteries: dark energy. New findings show that evolving dark energy models, tied to ultra-light axion particles, may better fit the universe's expansion history than Einstein's constant model. The ...

Physicists have uncovered how direct atom-atom interactions can amplify superradiance, the collective burst of light from atoms working in sync. By incorporating quantum entanglement into their models, they reveal that these interactions can enhance ...

Astronomers observed a massive, multi-temperature plasma eruption from a young Sun-like star, revealing how early solar explosions could shape planets. These fierce events may have influenced the atmosphere and life-forming chemistry of the early ...

Researchers at Maynooth University have achieved a forensic milestone by revealing fingerprints on fired bullet casings using a safe electrochemical process. The method uses mild voltage and non-toxic materials to make hidden ridges visible within .. ...

Spacetime isn't something that exists; it's a model for describing how events happen. Treating events as objects creates philosophical confusion and fuels misconceptions, such as time-travel paradoxes. Recognizing that events merely occur within an . ...

A team of astronomers used the James Webb Space Telescope to create the first 3D atmospheric map of an exoplanet. The fiery WASP-18b, a massive "ultra-hot Jupiter," revealed striking temperature contrasts, including regions so hot they destroy water ...

Scientists have achieved a breakthrough in light manipulation by using topological insulators to generate both even and odd terahertz frequencies through high-order harmonic generation (HHG). By embedding these exotic materials into nanostructured .. ...

Cambridge researchers have engineered a solar-powered "artificial leaf" that mimics photosynthesis to make valuable chemicals sustainably. Their biohybrid device combines organic semiconductors and enzymes to convert CO and sunlight into formate with ...

Researchers uncovered that trace compounds like nickel and urea may have delayed Earth's oxygenation for millions of years. Experiments mimicking early Earth revealed how their concentrations controlled cyanobacterial growth, dictating when oxygen .. ...

More screen time among children and teens is linked to higher risks of heart and metabolic problems, particularly when combined with insufficient sleep. Danish researchers discovered a measurable rise in cardiometabolic risk scores and a metabolic . ...
