New Research Reveals Mitochondrial Guardians Linked to Parkinson’s and ALS

Scientists at Johns Hopkins Medicine say they have discovered how a group of proteins linked to Parkinson's disease and amyotrophic lateral sclerosis act as "guardians" of mitochondria, small organelles, or subunits, within a cell that make and store energy and are found in almost all plants and animals.

Study Sheds Light on Evolutionary Role of Microglia in the Peripheral Nervous System

In a study published in Cell on April 7, a research team led by Prof. Li Hanjie from the Shenzhen Institutes of Advanced Technology (SIAT) of the Chinese Academy of Sciences has revealed the presence of microglia in the peripheral nervous system (PNS) and identified their crucial role in regulating neuronal soma size throughout evolution.

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 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.

Antibiotic Resistance Through Bacterial Genes Inhibiting Viral Reproduction

Antibiotic resistance is a global health threat that could supplant cancer mortality within a few decades. Researchers at Umeå University, Sweden, found that the emergence of resistance can be explained by how bacteria develop defenses against virus infection.
