Genetics

Genetics is the study of genes and heredity. Heredity is the passing of genetic information and traits (such as eye color and an increased chance of getting a certain disease) from parents to offspring.

Menopausal hormone therapy shows no added breast cancer risk for BRCA carriers

Using menopausal hormone therapy (MHT) was not associated with an increased risk of breast cancer in women with inherited mutations in the BRCA1 or BRCA2 genes, according to the results of a matched prospective analysis presented at the San Antonio Breast Cancer Symposium (SABCS), held December 9-12, 2025.

Massive genetics study shows what truly separates and unites 14 psychiatric disorders

This large-scale genomic analysis of 14 psychiatric disorders shows that most heritable risk is shared across five broad genetic factors, with only limited disorder-specific variation. The study maps where risks converge or diverge biologically, revealing distinct cell type signatures and developmental pathways that may guide future diagnostic and therapeutic frameworks.

Screen time and ADHD: why social media stands out from gaming and TV

Over four years in a large US cohort, greater social media use was associated with small but consistent increases in inattention symptoms in children, while video games and television were not. Genetic risk for ADHD did not modify this inattention association, and analyses supported a directional link from social media use to later attention difficulties.

Tec-Dara could represent a new standard of care for relapsed or refractory multiple myeloma

Patients with relapsed or refractory (R/R) multiple myeloma who received a combination of teclistamab, a bispecific monoclonal antibody, and daratumumab, a CD38-directed monoclonal antibody, were 83% more likely to be alive without disease progression compared with those who received standard second-line therapies at a median of nearly 35 months of follow-up, according to the results of a new trial presented at the 67th American Society of Hematology (ASH) Annual Meeting and Exposition.
