Scientists from the United States and Germany said they had succeeded in keeping transplanted pig hearts alive in baboons, primate cousins of humans, for a record 2.5 years. Their method uses a combination of gene modification and targeted immune-suppressing drugs.In recent experiments with five baboons, the hearts survived for up to 945 days, breaking previous records held by the same group of scientist and researchers.The hearts did not replace those of the monkeys, but were connected to the circulatory system via two large blood vessels in the baboon abdomen.Pigs have since emerged as better donors. Their hearts are anatomically similar to ours, they pose less of a disease transmission risk, they grow up fast and are already widely farmed. In these xenotransplant trials, baboons serve as human models.
Semiconductor Industry 2026: 2nm GAA, Chiplets & AI Hardware Trends. Introduction: A New Era for the Semiconductor Industry The semiconductor industry in 2026 is undergoing a historic transition. Traditional transistor scaling alone is no longer enough to sustain performance growth. Instead, the industry is being redefined by three powerful forces: 2nm-class process nodes using Gate-All-Around (GAA) transistors Advanced chiplet and 3D IC packaging Specialized AI-optimized hardware This shift marks the move from pure Moore’s Law scaling to system-level innovation , where packaging, architecture, and AI workloads drive the roadmap. 2nm Technology: The Commercial Arrival of GAA Transistors Why FinFET Reached Its Limits For years, FinFET technology powered leading chips. However, at extremely small nodes, FinFET structures struggle with: Increased leakage current Poor electrostatic control Power inefficiency at scale To overcome these challenges, foundries have transitioned ...
