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.

Cities Integrating AI Into Public Services With No Common Framework for Assessing Readiness, Oxford Insights Finds6.10.2026 04:00:00 CEST | Press release
Organisation behind the Government AI Readiness Index proposes a City AI Readiness Index, based on a new study of Abu Dhabi Cities are integrating artificial intelligence into public services and operations with no shared framework for measuring or comparing how prepared they are to do so safely, effectively or accountably. This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20261005281462/en/ Cover of Oxford Insights' latest report on City AI Readiness. (Graphic: AETOSWire) Existing global indices compare countries on legislation, investment and research output, but the AI efforts happening at city level – the level of government where the technology most directly shapes daily life – are not systematically captured. To start closing that gap, Oxford Insights researchers studied AI readiness across six cities. They found that all share the same core priorities, from governance and funding to talent and infrastructure, but take dist
NEG Develops “BDX-3,” a New Starveil™ Ultra-thin Cover Glass for a Wider Range of Space Environments6.10.2026 03:00:00 CEST | Press release
Nippon Electric Glass Co., Ltd. (NEG) (TOKYO: 5214) has developed “BDX-3,” a new Starveil™ ultra-thin cover glass for space applications. BDX-3 is designed to reduce radiation-induced discoloration while providing greater ultraviolet (UV) shielding performance than BDX-2. While primarily intended for low Earth orbit (LEO), it can also be used in medium Earth orbit (MEO) and high Earth orbit, making it suitable for a wider range of space environments. Samples are now available for purchase, and NEG aims to achieve commercial adoption of BDX-3 in satellites and other spaceborne equipment. About BDX-3 Satellites and other equipment operating in space are exposed to intense UV radiation and other forms of radiation. Low Earth orbit is widely used for Earth observation and communications, medium Earth orbit for positioning systems, and high Earth orbit for communications and weather observation. Cover glass used in these environments must not only protect precision equipment from harsh cond
