18.12.2023 15:01:32 CET | Business Wire | Press release
Seoul Semiconductor Co., Ltd. (KOSDAQ:046890), a global optical semiconductor company, announced on December 18 that it has verified through an experiment that natural spectrum lighting can promote stable growth and increase the content of effective nutrients in plants as daylighting does for plants grown in nature.

Seoul Semiconductor used both regular white LED lights and SunLike natural spectrum LED lights to grow lettuce, a vegetable commonly used as a food ingredient. The use of SunLike LED lighting resulted in an increase in lettuce yield and a significant increase in chlorogenic acid and chicoric acid, which are antioxidants and important nutrients, by more than 30% compared to the use of regular white LED lighting.
Seoul Semiconductor has been operating its own plant cultivation and research farm for the past 10 years. It studies growth and nutrient changes in a great variety of plants and nuts brought about by different light sources while measuring nutrients and conducting experiments on the effects of nutrients on cells.
In this comparative experiment, a regular white LED and a light equipped with a SunLike LED similar to a natural light spectrum – both of the same brightness – were installed separately, and the yields of lettuce and the contents of the antioxidants – chlorogenic acid and chicory acid – were compared for 3 weeks. Chlorogenic acid and chicoric acid are known for removing free radicals from the body, suppressing aging and inflammation, and preventing diseases such as aging, reduced vision, Alzheimer's, and arthritis.
The results show that the yield of lettuce grown under SunLike LED lighting increased slightly by 4% compared to regular white LED lighting, whereas chlorogenic acid and chicory acid increased by 55% and 31%, respectively. This confirms that using lighting closer to natural light in cultivation leads to higher nutrient content in plants.
Light spectrums affect plants and animals. Exposure to artificial light can interfere with frogs’ mating behavior, resulting in mutant tadpoles, and causing a 10-20% decrease in yields of sesame and other fruits. Sunflowers, for which the natural light spectrum was not used, suffered a decrease in bee visits.

The New World ID: Proof of Human for the AI Era Scales Across the Digital Platforms People and Businesses Use Every Day24.4.2026 02:20:00 CEST | Press release
Docusign, Okta, Tinder, Vercel, and Zoom bring World ID proof of human to businesses, AI agents, and consumers Last week, World announced the next generation of World ID, its proof of human protocol, designed to increase trust on the internet. The announcement was made during “Lift Off,” a live event in San Francisco. This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20260417530721/en/ Docusign, Okta, Tinder, Vercel, and Zoom bring World ID proof of human to businesses, AI agents, and consumers As AI makes it easier than ever to generate convincing content, identities, and interactions, trust online has decreased. World ID addresses this challenge by enabling individuals to privately prove they are a real, unique human, without revealing their identity across apps, platforms, and services. “If anything online can be faked, you no longer know who or what to trust,” said Tiago Sada, Chief Product Officer at Tools for Humanity, a co

Does Muscle Composition Identify High-Risk Individuals in Chronic Kidney Disease? New AMRA Medical Study Says Yes, Reveals Strong Link to Mortality23.4.2026 17:10:00 CEST | Press release
AMRA Medical researchers recently set out to answer the question: what is the relationship between adverse muscle composition (AMC) and mortality in kidney disease? Recent findings demonstrate that AMC, characterized by low muscle volume z-score and high muscle fat infiltration, is an independent and strong predictor of all-cause mortality in individuals with chronic kidney disease (CKD). The findings, published in Clinical Journal of the American Society of Nephrology, were based on data from the UK Biobank imaging study and further reinforce the clinical relevance of MRI-derived muscle biomarkers in identifying high-risk populations across chronic diseases.
