Rattling DNA hustles transcribers to targets

Imagine if a dense thicket didn't obstruct your path but instead picked you up and shuttled you through the forest. That's what tightly packed DNA might be doing with important life molecules to get them where they're needed ...

Microbes seen controlling action of host's genes

All animals—from sea sponges to modern-day humans—evolved in a world already teeming with microbes. These single-celled microorganisms now cover practically every surface of our bodies and are as much a part of our biology ...

Scientists reveal how epigenetic changes in DNA are interpreted

A new study in Science from Karolinska Institutet maps out how different DNA-binding proteins in human cells react to certain biochemical modifications of the DNA molecule. The scientists report that some 'master' regulatory ...

The origin of stem cells

Freiburg plant biologist Prof. Dr. Thomas Laux and his research group have published an article in the journal Developmental Cell presenting initial findings on how shoot stem cells in plants form during embryogenesis, the ...

New stem cell technique shows promise for bone repair

A recent study, affiliated with UNIST has developed a new method of repairing injured bone using stem cells from human bone marrow and a carbon material with photocatalytic properties, which could lead to powerful treatments ...

SMiLE-seq: A new technique speeds up genetics

Scientists at EPFL have developed a technique that can be a game-changer for genetics by making the characterization of DNA-binding proteins much faster, more accurate, and efficient.

Gene "bookmarking" regulates the fate of stem cells

A protein that stays attached on chromosomes during cell division plays a critical role in determining the type of cell that stem cells can become. The discovery, made by EPFL scientists, has significant implications for ...
