Police in Japan have arrested a 57-year-old man on suspicion of drunk driving after his kei light truck collided with a motorcycle, leaving the 16-year-old rider and a 15-year-old girl seriously injured. The suspect reportedly told investigators he believed the alcohol had mostly worn off. The case has drawn attention to repeat concerns over drunk driving and kei truck safety.

A new explanation is drawing attention to why insects gather around artificial lights at night: rather than being attracted to the glow, they appear to become disoriented, tilting and circling as their steering reflexes confuse the light for the sky. The claim, laid out in a detailed write-up, challenges the long-held 'moth to a flame' idea and is sparking discussion about what LED street lighting really does to insect behaviour.

South Korean LED maker Seoul Viosys has begun mass production of a white light emitter that contains no rare-earth phosphors, a notable shift since conventional white LEDs rely on rare-earth elements such as yttrium and cerium. The announcement is drawing attention amid ongoing supply-chain concerns over rare-earth materials and export restrictions, with discussion focusing on what the technology means for lighting manufacturing.
- 4iPhone trick: make its light flash so you can find it▼How to make your iPhone's light flash when you can't find it
A guide explains how to set an iPhone so its light flashes, helping owners locate the phone when it is misplaced. The feature can be enabled through the device's accessibility settings, allowing the LED flash to blink when an alert arrives or when triggered to help find the phone in the dark or under cushions. Readers are sharing the tip as a simple but little-known setting.
- 5Bonn lights up with greeter-led city tours this weekend●Wer möchte Bonn mal in ganz anderem Licht erleben? Und vorher mit einem Greet die Stadt kennenlernen? Am Wochenende geht
Bonn is hosting 'Bonn leuchtet' this weekend, a light event organised by the city's marketing office, and visitors can pair it with a free walk led by a local greeter. Bonn Greeters, a volunteer group offering personalised city tours, is inviting people to discover the city in a completely different light by combining an evening of illuminated sights with an introduction from a resident.
- 6SKKU Develops Ultra-Low-Defect Thin Films for Solar Cells and LEDs●SKKU Develops Ultra-Low-Defect Semiconductor Thin Films through Eutectic Engineering, Enabling Both Solar Cells and LEDs | Newswise
Researchers at Sungkyunkwan University in South Korea have developed ultra-low-defect semiconductor thin films using eutectic engineering, a materials technique that reduces crystalline flaws. The advance is reported to allow the same film technology to be applied to both solar cells and light-emitting diodes, improving efficiency prospects in both energy conversion and display or lighting applications. Details of the research were published via Newswise.
