An MIT study suggests some early life forms may have evolved the ability to use oxygen hundreds of millions of years before the Great Oxidation Event, when oxygen became a permanent fixture in the atmosphere. The findings may represent some of the earliest evidence of aerobic respiration on Earth. 

Cancer cells often invade different tissues by forming rounded protrusions called blebs. However, the exact mechanism behind this expansion remained unclear. Now, researchers at Kyushu University have discovered that cancer cells use protein clusters to create water pressure inside blebs, which pushes the cell membrane outward, enabling rapid movement. This newly identified mechanism, named “CaMKII-based osmotically-driven deformation or CODE,” reveals a unique physical process that drives the spread of cancer cells inside the body.

A research team from the Wuhan National Laboratory for Optoelectronics (WNLO) and the School of Optical and Electronic Information at Huazhong University of Science and Technology (HUST) has reported a new advancement in all-perovskite tandem solar cells. By utilizing quantitative Silvaco TCAD simulations, the team has elucidated the fundamental physics of the tunnel junction, providing a definitive design rule to overcome efficiency bottlenecks in all-perovskite tandem solar cells.

Iron-based molecular sieves show great promise for high-temperature NH₃-SCR due to their intrinsic shape selectivity and thermal stability. However, excessive ammonia oxidation at high temperatures limits NO_x conversion and long-term stability, and its kinetic transition remains poorly understood. A team led by Zhiqiang Sun, Hanzi Liu, and Xinlin Xie has developed a high-temperature Fe@ZSM-5 catalyst and established a coupled kinetic model to describe ammonia oxidation behavior at high temperatures. Their work was published in the journal Industrial Chemistry & Materials in December 2025.
