Researchers identify how eye loss occurs in blind cavefish

Loss of eye tissue in blind cavefish (Astyanax mexicanus), which occurs within a few days of their development, happens through epigenetic silencing of eye-related genes, according to a study led by the National Institutes ...

Does physical activity influence the health of future offspring?

Physical and mental exercise can affect the learning ability of future offspring, at least in mice. This particular form of inheritance is mediated by certain RNA molecules that influence gene activity. These molecules accumulate ...

Decoding behavioral variation in ant clones

Genetically identical clonal ants show surprising diversity in their attraction to sweetness, according to new research in the journal Royal Society Open Science. While differences in behavior and preferences among a species ...

A clonal crayfish from nature as a model for tumors

A genome study has proven that all specimen of Marmorkrebs, or marbled crayfish, originate from a single female. About 30 years ago, the original clone evolved in an aquarium. Ever since, the female animals have been able ...

Chromosome organization emerges from 1-D patterns

The DNA in a human cell is 2 yards (1.83 meters) long and wraps around millions of bead-like histone proteins to fit inside the cell's nucleus. Researchers at Rice University and Baylor College of Medicine showed that examining ...

An epigenetic key to unlock behavior change

When it comes to behaviour, researchers have moved beyond the "nature versus nurture" debate. It's understood that genes and environment both play a role. However, how they interact at a molecular level to shape behaviour ...

Revolutionary process could signal new era for gene synthesis

A team of scientists led by the University of Southampton has demonstrated a groundbreaking new method of gene synthesis - a vital research tool with real-world applications in everything from growing transplantable organs ...
