Researchers have discovered naturally occurring photocurrents in iron and manganese mineral coatings on rocks in China. These coatings exhibit stable photocurrents under steady illumination and rapid changes with illumination fluctuations, suggesting a potential role in biogeochemical processes.
Scientists developed Virtual Frame Technique (VFT) to generate thousands of images of fast phenomena, using conventional photos from any device. VFT performs better than high-speed cameras and has been used for various applications, including droplet impacts and fracture mechanics.
Salk scientists discovered that melanopsin cells, responsible for regulating consciousness and sleep, respond to prolonged illumination, but can become desensitized. The study may lead to new treatments for migraines, insomnia, jet lag and circadian rhythm disorders.
Researchers at Osaka University have created a new form of art illumination that uses synchronized fluctuations in light to mimic natural rhythms, creating a unique and cozy setting. This technology has the potential to enhance quality of life by providing a more human-friendly and nature-inspired lighting solution.
Researchers at Aalto University developed a new computational method to address the challenge of computing realistic indirect illumination in real-time computer graphics. The novel method accurately computes indirect illumination using sparse radiance probes, enabling fast and accurate lighting simulations.
A novel technique adapts image contrast to eliminate lighting effects, improving face recognition accuracy. The method uses an extended reflectance model with Fuzzy Inference System and Genetic Algorithm for real-time implementation.
Researchers have improved Structured Illumination Microscopy (SIM) to achieve 62-nanometer resolution, reducing phototoxicity and improving imaging of proteins interacting. This breakthrough has provided new insights into cell processes, such as the role of actin in clathrin-mediated endocytosis.
International experts warn about the adverse effects of exposure to light at night, particularly LED lighting, on circadian rhythms in nature and human health. The panel highlighted the harm caused by short-wavelength illumination to various species, including mammals, birds, and plants.
A new electronic system created by researchers from the University of Granada improves driving ability at night using information extracted from night visors. The system makes intelligent cars more sophisticated by informing drivers about obstacles on the road.
A recent study examines the remarkable two-tone color of pumpkin seed oil using imaging and CIE chromaticity coordinates. The observed color shift from red to green is attributed to changes in oil layer thickness and unique human retina cell characteristics.
A new UCL study reveals that bees can recognize flowers under different global lights by segmenting scenes into regions of illumination and finding the correct flowers within each region. This strategy suggests that bees use color relationships between objects in a scene to resolve stimulus ambiguity, a challenge also faced by humans.
A study by Vanderbilt University researchers reveals that biological clocks enhance the fitness of organisms by adapting to daily environmental changes. However, when illuminated constantly, these internal pacemakers become obsolete and can even hinder growth, according to the research.
A study found that people with type 2 diabetes experienced increased oscillatory potentials after dark adaptation, which decreased with oxygen inhalation. The researchers suggest that diabetic patients might benefit from a modified night-time illumination cycle during sleep to reduce oxygen consumption in the retina.
Research by Margriet van Eikema Hommes shows that shadows in Raphael's painting became darker over time, changing the contrast and creating a theatrical effect. The study provides insights into the original composition of Renaissance paints and their aging process.
