The mysterious substance that binds galaxies together could naturally be "in tune" with a hidden fifth dimension, according to a new University of Sheffield theory aiming to shed light on one of science's biggest enigmas: dark matter.
For over a century, the accepted value for a firefly's brightness has mostly stood, tracing its origins to experiments carried out in 1912. Through rigorous new analysis published in the American Journal of Physics, David Silver of Remiza AI in New York has discovered that this value has likely been vastly overestimated. His results provide a stark reminder of what can happen when widely accepted older measurements are converted into modern standard units.
Large language models (LLMs) are gradually transforming research in the life sciences in ways that extend far beyond improving productivity, and they are becoming a new normal before scientists have agreed on the limits of their use.
With international football facing increasing criticism over its carbon footprint, University of Bath students are working with Bath City FC to show how community football could help tackle climate change.
Our universe is known to be remarkably homogeneous and isotropic. This essentially means that matter is distributed evenly throughout the universe and that it looks almost the same in all directions.
Pyrite, an iron sulfide ore, is often known as fool's gold because its shiny metallic luster and pale brass-yellow color can easily fool the untrained eye into mistaking it for real gold. This time, however, 360 kilometers (220 miles) south of Tokyo, scientists have uncovered invisible gold within pyrite structures found deep beneath the ocean at the Higashi-Aogashima Knoll Caldera hydrothermal field.
Korean researchers have developed, for the first time in Korea, a 200Gbps-class photodetector device for use in hyperscale AI data centers and 5G/6G mobile communications infrastructure. The technology enables ultrahigh-speed data reception fast enough to transmit five 5GB full HD movies per second. The results of this study were presented at OECC 2025, held in Sapporo, Japan, and were recently published in Optics Express.
Researchers at Nagoya University in Japan have developed a method to form dome-shaped bumps on nanofilms in water using a computer-guided electron beam. The bumps form within 10 seconds and can be flattened, reshaped or repositioned as needed.
Untreated synthetic dye effluents severely threaten aquatic ecosystems by blocking sunlight, depleting dissolved oxygen and releasing compounds with potential ecological toxicity. Among the various treatment strategies, biological treatment is considered a cost-effective and environmentally friendly alternative to chemical methods.
In a study recently published in the journal Environmental Research, scientists from the University of Sharjah have drawn renewed attention to contamination by polybrominated diphenyl ethers (PBDEs), a class of man-made chemicals formerly used as flame retardants in a wide range of products, including electronics, household appliances, vehicles, furniture and upholstery.
