New Study Reveals How Introns Jump Between Species Without Viral Help

Jumping genes are parasites in the genetic material of bacteria, plants, animals and humans. They are released into the cell as small RNA molecules from ribonucleic acid (RNA) and possess complex mechanisms for inserting themselves into other parts of the genetic material within the cell, thereby often conferring new properties on the cell and thus accelerating evolution. There are also jumping genes that free themselves from the RNA using an RNA enzyme. These ribozymes or self-splicing introns are a special group of jumping genes.

New Research Examines How Blood Cancer Mutations Progress from Healthy States

Researchers have found that a genetic mutation associated with a rare group of blood cancers does not always result in development of the disease. The work provides insight into the initial phases of the disease and may eventually lead to tailored monitoring techniques that improve patient outcomes.

Single-Cell Analysis Uncovers How Cancer Tumors Diversify and Resist Treatment

A comprehensive multi-cancer study from researchers at The University of Texas MD Anderson Cancer Center has revealed that cancer cells within tumors are genetically diverse, yet all carry the same core genetic changes that can be traced back to a common ancestral cell, providing a single-cell view of how tumors adapt, survive and diversify. Understanding this helps explain why some cancer cells manage to survive treatments, paving the way for more tailored diagnostic and therapeutic strategies.

Artificial Intelligence Translates Raw Micro CT Scans Into 3D Virtual Stains

Rudolf Virchow fundamentally changed medicine when he formulated his cell theory of disease in the 19th century: diseases do not arise inexplicably within the organism, but rather in specific cells and tissues.

Migrating Neurons Break and Repair Their Own DNA During Brain Cortex Formation

Newborn nerve cells must squeeze through crowded, narrow spaces-through dense tissue, past other cells, between fibers-to reach the areas where they form neural circuits in the brain cortex.
