LG Electronics reported an operating loss of 109.4 billion won ($75.2 million) for the fourth quarter of 2025, swinging from a profit the year before due to U.S. tariffs and weak demand. Annual revenue hit a record 89.2 trillion won, up 1.7%, but operating profit fell 27.5% to 2.48 trillion won.
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.

Samsung Display announced on January 7 that it has developed SmartPower HDR technology with U.S.-based Intel, reducing power consumption in laptop OLED displays by up to 22 percent. The innovation dynamically adjusts voltage according to content characteristics, extending battery life and enhancing the HDR viewing experience. It is expected to significantly boost battery efficiency amid the growing popularity of AI PCs.
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.
