Spinning Into Resistance: The Flagella’s Hidden Role

A new study from the Hebrew University of Jerusalem reveals that bacterial movement plays a central role in the transfer of antibiotic resistance genes. The research team discovered that the rotation of flagella in Bacillus subtilis acts as a mechanical signal that activates key conjugation genes.

Study Reveals How Stiffened Osteocytes Contribute to Bone Loss in Aging

It's no coincidence that our bodies feel a little creakier as we age. The trillions of cells that make up our skeleton age too, and some change in ways that weaken the very structure of our bones.

Scientists Capture Dynamic Process of Chromatin Remodeling in Action

Chromatin remodeling plays a vital role in gene regulation, affecting how DNA is accessed. Disruptions in this process can also lead to cancer and other diseases.

Scientists Discover Epigenetic Marks in Pancreatic Cancer Transition

Johns Hopkins Medicine scientists say they have found a pattern of so-called epigenetic "marks" in a transition state between normal and pancreatic cancer cells in mice, and that the normal cells may keep at least a temporary "memory" of those cancer-linked marks.
