The present theory offers a unified solution to three closely related evolutionary problems. (1) Why does an evolving population explore only a small fraction of the accessible pathways in genotype ...

Researchers still do not have a comprehensive picture of the factors that influence gene expression in human cancers. Understanding gene expression in cancer is important because it can reveal how the ...

For more than a century, Mendelian genetics has shaped how we think about inheritance: one gene, one trait. It is a model that still echoes through textbooks—and one that is increasingly reaching its ...

Genetic variability and sex-specific differences may play a role in sickle cell disease (SCD)-related pain; however, more research is needed. In the present study, saliva samples from 59 adults with ...

A study expands the list of known genes with circadian variation and provides the first comprehensive list of genes with seasonal variation in each tissue. Tissues in the thoracic cavity, such as the ...

For many years, scientists have known that genetic variants, or differences in DNA code across people, play some role in neurological and psychiatric disorders. But the details were murky. Now, ...

Gene banks worldwide make an important contribution to the conservation of biological diversity. In addition to negative traits, old and exotic varieties possess many valuable gene variants that have ...

A multi-university research team co-led by University of Virginia engineering professor Gustavo K. Rohde has developed a system that can spot genetic markers of autism in brain images with 89 to 95% ...

Professor Sang Cheul Oh of the Division of Oncology/Hematology, Department of Internal Medicine, Korea University College of Medicine, Professor Sang‑Hee Kang of the Department of Surgery, Korea ...

A new UCLA Health study has found that certain genetic variants could help explain how long-term pesticide exposure could increase the risk of Parkinson's disease. While decades of research have ...
