Phase transition inside the nucleus provides oncogenic function to mutant p53 in cancer

Researchers at Federal University of Rio de Janeiro discover a crucial link between phase transition and cancer pathology. Mutant p53 aggregates are formed through liquid-to-liquid phase separation, progressing to a gel-like or solid-like state that plays a key role in cancer development.

First detailed look at how charge transfer distorts a molecule's structure

A SLAC X-ray laser study reveals the molecular structure changes during charge transfer in N,N'-dimethylpiperazine (DMP) gas molecules. The research team observed how the molecule's atomic scaffolding deforms and redistributes charges, leading to a lopsided response to light.

Little to no increase in association between adolescents' mental health problems and digital tech

A new study published in Clinical Psychological Science found little evidence of increased association between adolescents' technology engagement and mental health problems. Only social media use showed a slight increase in emotional problems, while other associations remained consistent or decreased over time.

Mangroves and seagrasses absorb microplastics

A recent study published in Environmental Science and Technology found that mangroves and seagrasses capture higher concentrations of microplastics than control sites. The study's lead researcher notes that the accumulation of microplastics in these ecosystems may have negative impacts on animal and plant life.
