Superconducting diodes, which enable dissipationless one-way current flow, have long been limited by low operating temperatures and scalability. Now, writing in National Science Review, a team from Nanjing University reports scalable high-temperature superconducting diodes based on intrinsic Josephson junctions. The devices operate up to 86 K, show tunable nonreciprocity, and exhibit zero-field memory effects, providing a practical route toward energy-efficient superconducting electronics.

Artificial intelligence is fundamentally transforming chemical engineering across all sub‑disciplines, from reaction engineering and catalyst design to process control, materials discovery, and plant operations. This review highlights how machine learning and digital twins are enabling real‑time process optimization, predictive safety monitoring, and sustainable manufacturing. Foundation models and autonomous laboratories are accelerating molecular and materials discovery, while large language models extract structured knowledge from scientific literature. The convergence of AI with chemical engineering is driving a paradigm shift toward smarter, greener, and more efficient production systems.

New research presented today at the International Society for Stem Cell Research (ISSCR) 2026 Annual Meeting explores an approach that could expand the potential of cell replacement therapy for type 1 diabetes by evaluating whether immune-engineered, allogeneic insulin-producing cells can survive and function without chronic immunosuppression.

The study addresses one of the field’s central challenges: overcoming immune rejection, which has limited the broader use of islet and stem cell-based replacement therapies for type 1 diabetes.
