Single nucleosomes tracked in live cells during cell division using super-resolution microscopy
Individual cells divide through a process called mitosis, during which the cell's copied DNA is separated between two resulting daughter cells. Despite recent advances in cell biology, the mechanism by which DNA condenses during mitosis is still poor.....»»
New study uncovers the complex dynamics of self-deprecating remarks in Korean entertainment
Self-deprecation, a negative self-assessment used in social interaction, is prevalent in Korean reality TV shows. Traditionally, psychology views self-deprecation as indicative of low self-esteem or related psychological disorders, such as depression.....»»
Cryo-ET study elucidates protein folding helpers in their natural environment

Novel ratchet mechanism uses a geometrically symmetric gear driven by asymmetric surface wettability
The ratchet mechanism is a fascinating energy-conversion system that converts disorderly or random motion into orderly, directed movement through a process known as spontaneous rectification. It is a critical component of mechanical systems, typicall.....»»
Physicists successfully observe Kibble–Zurek scaling in an atomic Fermi superfluid
The Kibble–Zurek (KZ) mechanism is a theoretical framework introduced by physicists Tom Kibble and Wojciech Zurek. This framework essentially describes the formation of topological defects while systems undergo non-equilibrium phase transitions......»»
Researchers shed light on how to make photopolymerization much more efficient
Polymers are materials made out of long, repeating chains of molecules, and it is the interaction between these chains that dictates most of a polymer's physicochemical properties. In accordance with this intuitive understanding of polymers, which da.....»»
Morphable materials: Researchers coax nanoparticles to reconfigure themselves
A view into how nanoscale building blocks can rearrange into different organized structures on command is now possible with an approach that combines an electron microscope, a small sample holder with microscopic channels, and computer simulations, a.....»»
Scientists uncover exciton behavior in van der Waals magnets
A research group led by scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory has uncovered details about the formation and behavior of mobile, microscopic, particle-like objects called "excitons" in a class of materials.....»»
