Through the backdoor: How phosphate escapes from actin

The discovery sheds light on the mechanism of phosphate release from actin filaments, which is crucial for cell movement and disassembly. The researchers found that phosphate escapes through a molecular backdoor in the filament core, but the door remains closed for most of the time.

For the lonely, a blurred line between real and fictional people

Researchers found that lonely individuals' brains show a blurred boundary between real friends and favorite fictional characters, such as those in Game of Thrones. The study suggests that lonelier people may turn to fictional characters for a sense of belonging lacking in their real life.

Researchers uncover why a gene mutant causes young children to have strokes

Researchers discovered that a mutation in the gene ACTA2 causes moyamoya disease and strokes in young children.
