LG전자가 2025년 4분기 영업손실 1094억 원(약 7520만 달러)을 기록했다고 발표했다. 이는 전년 동기 흑자에서 적자로 전환된 것으로, 미국 관세와 수요 부진이 주요 원인이다. 연간 매출은 892억 원으로 사상 최고를 기록했으나 영업이익은 27.5% 감소했다.
Labor unions at major Japanese electronics makers have launched this year's spring wage negotiations in earnest, demanding a monthly pay scale increase of ¥18,000, surpassing last year's record-high request.

Researchers at Japan's RIKEN Center for Emergent Matter Science have pioneered a method to carve three-dimensional nanoscale devices from single crystals using focused ion beams. By shaping helical structures from a magnetic crystal, they created switchable diodes that direct electricity preferentially in one direction. This geometric approach could enable more efficient electronics.
Scientists have developed a working memory chip just 10 atoms thick, integrated with conventional chips to potentially boost storage in smartphones and other electronics. The prototype, made from 2D materials, addresses limits in current chip stacking. While promising, experts note it is far from commercial readiness.

Researchers have achieved a breakthrough by pushing electrons in graphene to supersonic speeds, creating a hydraulic jump similar to a sonic boom. This experiment, conducted using a microscopic nozzle, marks the first observation of such electron behavior. The findings could help resolve debates on electrically charged shockwaves.
