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...

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...
Scientists have utilized genome editing technology to create a chicken egg with reduced allergenic properties. Image Credit: Canvas Allergies to eggs are highly prevalent among children and can be provoked by various food items, including vaccines. However, scientists have recently utilized genome editing technology to create a chicken egg that could potentially be consumed by...
Credit: Canva In a potential game changer for the treatment of superbugs, a brand-new class of antibiotics was developed that cured mice infected with bacteria regarded virtually "untreatable" in humans-- and resistance to the drug was undetectable. Produced by a research team of UC Santa Barbara researchers, the research study was released in the journal eBioMedicine....
Graphical abstract. Credit: Biochemical and Biophysical Research Communications (2022). DOI: 10.1016/j.bbrc.2022.12.080 A team of undergraduate and also graduate chemistry students in Jennifer Hines' laboratory at Ohio University recently uncovered a current class of compounds that can target RNA and disrupt its function. This discovery determined a chemical scaffold that might ultimately be utilized in the development of...
Credit: CC0 Public Domain More than 10% of older adults create somatic (non-inherited) mutations in blood stem cells that could trigger explosive, clonal expansions of abnormal cells, enhancing the risk for blood cancer and heart disease. Multiple DNA sequencing techniques have been utilized to determine what is called "clonal hematopoiesis of indeterminate potential," or CHIP. Still,...
