A common birthplace of new genes, the male testes are a hotspot for biological innovation. Within these organs, scientists have found a trove of virgin genetic sequences--and a better understanding of how evolution moves forward.
A researcher at the OU College of Medicine, William R. Lovallo, Ph.D., recently published one of the field's few studies focused on how a person's genes contribute to addiction. Lovallo's research showed that a tiny genetic mutation can put people at higher risk for alcohol or drug addiction.
'A study like this makes it clear that even though we may think we know everything there is to know about the opioid response, we're actually just scratching the surface.' -- Kirill Martemyanov, PhD, Scripps Research Neuroscience Co-Chair
An understanding of the molecular basis of differences in the incidence and survival of cancer between men and women may allow the discovery of specific and more effective treatments. The study, published in Science Advances, compares the brain tumours of male and female flies at the molecular level and identifies proteins responsible for the different degree of aggressiveness.
Scientists have found how to relieve a bottleneck in the process by which plants transform sunlight into food, which may lead to an increase in crop production. They discovered that producing more of a protein that controls the rate in which electrons flow during photosynthesis, accelerates the whole process.
University of Queensland scientists have identified a way to help dermatologists determine a patient's risk of developing melanoma.
The molecular mechanism used by many bacteria to kill neighboring cells has redundancy built into its genetic makeup, which could allow for the mechanism to be expressed in different environments.
A Nature Communications paper by Worcester Polytechnic Institute biologist Jagan Srinivasan has shown that a key biological component in the communication system of the nematode C. Elegans can be repurposed to take on a different job,. This critical finding about the workings of evolution could one day affect research into drug interactions, agricultural bio-engineering, and a better understanding of genetic inheritance through multiple generations.
Scientists have recovered the first genetic data from an extinct bird in the Caribbean, thanks to the remarkably preserved bones of a Creighton's caracara from a flooded sinkhole on Great Abaco Island.
Modern science and data sharing converged to underpin a study led by TGen that identified a gene associated with a rare condition that results in physical and intellectual disabilities of children. The results, published today in the American Journal of Human Genetics, suggest that rare variants in the gene DDX6 are associated with a significant disruption in the development of the central nervous system, governing such basic skills as the ability to walk and talk.
