Bacterial Protein Structure Hints At Mechanism Of A Class Of Premature Aging Diseases

Scientists at Duke University have discovered that a bacterial protein structure plays a crucial role in preventing genetic flaws from translating into diseases. The research reveals that the protein interacts with helicases, which are involved in several genetic diseases, including Werner's syndrome and Cockayne's syndrome.

Mutant Flowers Mark A Breakdown In Male-Female Communication

Researchers at the University of Chicago Medical Center have identified a mutation in a small flowering plant that disrupts male-female communication, leading to pollen tubes wandering aimlessly. This defect is similar to self-sterility observed in many plant species, which helps maintain genetic diversity.
