Cell colonies under pressure – how growth can prevent motion

Max Planck Institute for Dynamics and Self-Organization
Peer-Reviewed Publication

The interaction between growth and the active migration of cells plays a crucial role in the spatial mixing of growing cell colonies. This connection was discovered by scientists from the Department of Living Matter Physics at the Max Planck Institute for Dynamics and Self-Organization (MPI-DS). Their results provide new approaches to understanding the dynamics of bacterial colonies and tumors.

Unveiling the 3D crystal secrets of defective nanoparticles

Japan Advanced Institute of Science and Technology
Peer-Reviewed Publication

Metal oxyhydroxides are nanoparticles with wide industrial applications, but determining their exact structure is often challenging. Recently, a research team from the Japan Advanced Institute of Science and Technology has developed an advanced imaging method called “lattice correlation analysis” to reveal the detailed 3D atomic structure of titanium oxyhydroxide nanoparticles. By leveraging data-driven insights, this method unlocks the crystal attributes without causing any damage, thus marking a milestone in the study of sensitive nanomaterials.

New era of magnetization: HKUST research sheds light on future applications in spintronics and valleytronics

Hong Kong University of Science and Technology
Peer-Reviewed Publication

Altermagnets, which exhibit momentum-dependent spin splitting without spin–orbit coupling (SOC) or net magnetization, have recently attracted significant international attention. A team led by Prof. LIU Junwei from the Department of Physics at the Hong Kong University of Science and Technology (HKUST), along with their experimental collaborators, published their latest research findings in Nature Physics*, which unveiled the first experimental observation of a two-dimensional layered room-temperature altermagnet, validating the theoretical predictions in Nature Communications made by Prof. Liu in 2021.
