South Korea's Impeached President Fosters Anti-Communist Sentiments Amid Impeachment Proceedings

Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed a self-learning memristor that could enhance neuromorphic computing and aid in replicating human brain functions. This chip, which can learn from errors, may allow artificial intelligence (AI) systems to perform tasks locally with improved energy efficiency and privacy, as revealed in a study published in Nature Electronics. Historically conceptualized by American engineer Leon Chua in 1971, memristors function as "memory resistors" and simulate synaptic activity in the brain. KAIST's recent advancement enables the chip to separate moving images from backgrounds and become more proficient over time. Researchers Hakcheon Jeong and Seungjae Han emphasized that this technology mimics the brain's efficient processing, likening it to a streamlined workspace. In tandem with its memristor innovations, KAIST has also unveiled its first AI superconductor chip, capable of high-speed processing while consuming minimal power. While these developments inch closer to creating a brain-on-a-chip, experts caution that such advancements do not equate to machines achieving comprehensive human-like intelligence.

Han Jong-hee, co-CEO of Samsung Electronics, passed away on March 25 at the age of 63 due to cardiac arrest. His death was confirmed by a company spokesperson, who stated that he was hospitalized at the time. Han led Samsung’s consumer electronics and mobile devices division, while co-CEO Jun Young-hyun managed their chip business. Having joined Samsung nearly 40 years ago, Han had a significant impact on the company, especially in the TV sector. He became vice-chair and CEO in 2022. Recently, however, the company has struggled with declining earnings and market share, particularly in advanced memory chips and smartphone sales, currently trailing behind competitors like Apple. According to reports, shareholders expressed concerns over Samsung's performance during a recent meeting, especially in light of the booming demand for AI-related products. Han was expected to participate in Samsung's upcoming launch event for new home appliances the day after his passing. A successor for his position has not been announced.

North Korea has revealed the construction of its first nuclear-powered submarine, a development that poses significant security concerns for South Korea and the United States. The state-run Korean Central News Agency (KCNA) reported on March 9, 2025, that Kim Jong Un inspected the shipyards where this submarine, described as a strategic guided missile vessel, is being built. Experts estimate the submarine to be approximately 6,000 to 7,000 tons, with a capacity to carry around ten missiles, potentially including nuclear-equipped weapons. Moon Keun-sik, a submarine expert at Hanyang University, expressed that the submarine represents a major threat, given its capability to launch missiles from underwater, making detection difficult for adversaries. U.S. National Security Council spokesman Brian Hughes mentioned that they are aware of the submarine claims but offered no further information. Concerns have also emerged regarding North Korea's ability to obtain the necessary resources and technology for such a project, with speculation about potential Russian assistance in exchange for military support against Ukraine. North Korea’s recent military rhetoric has intensified ahead of joint military exercises planned by the U.S. and South Korea.
