Researchers at the University of Michigan are now delving into the molecular-level details of sperm formation, focusing on protamines—a unique group of proteins that package sperm DNA. Understanding the significance of protamines may shed light on...
Credit: Pixaobay Scientists have made a groundbreaking discovery by identifying the genetic cause of virgin birth in an unexpected species, the fruit fly ''Drosophila melanogaster''. Once this ability is activated in a female fruit fly, it can be inherited by successive generations. In this process, females can reproduce either sexually with the presence of males...
We all have heard of Africa as the "cradle of humankind" or the "fountain of humankind”, due to the earliest evidence of human ancestors found here. A new research show on how the African ancestor mixture and a couple of truths on how they lived and connected came to light. A group of 44 researchers...
A new study has pinpointed the genes that shape our skeletons. Credit: The University of Texas at Austin Researchers from The University of Texas at Austin and New York Genome Center have harnessed AI (artificial intelligence) to analyze an extensive collection of X-ray images and genetic sequences, identifying genes responsible for shaping various aspects of...

Research team leader Joanne Cole, Ph.D., an assistant professor in the Department of Biomedical Informatics at the University of Colorado School of Medicine, stated that they have identified genes associated with sensory pathways, including taste, smell, and texture, which may also impact the brain's reward response. However, these genes could potentially be utilized...

What occurs when climate change is introduced into the equation is the potential for the emergence of new species worldwide, as various organism groups become distinct and follow separate evolutionary paths. In the publication "Contrasting effects of warming in diverging insects," which was recently released in Ecology Letters, Thomas H.Q. Powell, an assistant lecturer...

A recent research investigation revealed that the combination of radiotherapy and a virus designed to target cancer cells proved to be more successful in treating a challenging and fatal type of brain tumor compared to the individual use of either therapy. The National Brain Tumor Society reports that glioblastoma (GB) constitutes slightly more than half,...

A recent study led by researchers at Weill Cornell Medicine and the National Heart, Lung, and Blood Institute, a division of the National Institutes of Health, has found that DNA has the ability to imitate protein functions by adopting intricate and three-dimensional structures. A recent study, published in...

Examples of such stories include the birth of Mars, an ancient Roman god, Horus, an ancient Egyptian god, and Qi, a figure from ancient Chinese mythology, all of whom...
