Healthful Living May Lengthen Telomeres And Lifespans
As people age, caps called telomeres on the ends of their chromosomes shrink. The observation has led some scientists to argue the shortening is not only a marker of aging but a fundamental driver of it.

Scientists discover how rapamycin slows cell growth 
University of Montreal researchers have discovered a novel molecular mechanism that can potentially slow the progression of some cancers and other diseases of abnormal growth. In the May 23 edition of the prestigious journal Cell, scientists from the University of Montreal explain how they found that the anti-cancer and anti-proliferative drug rapamycin slows down or prevents cells from dividing.

The secret lives, and deaths, of neurons
As the human body fine-tunes its neurological wiring, nerve cells often must fix a faulty connection by amputating an axon — the "business end" of the neuron that sends electrical impulses to tissues or other neurons. It is a dance with death, however, because the molecular poison the neuron deploys to sever an axon could, if uncontained, kill the entire cell.

DNA damage: The dark side of respiration
Adventitious changes in cellular DNA can endanger the whole organism, as they may lead to life-threatening illnesses like cancer. Researchers at Ludwig-Maximilians-Universitaet (LMU) in Munich now report how byproducts of respiration cause mispairing of subunits in the double helix.

Mechanism discovered which aids Legionella to camouflage itself in the organism
The feared Legionella pneumophila bacteria is responsible for legionellosis, an infectious disease that can lead to pneumonia. In order to infect us, this pathogen has developed a complex method enabling it to camouflage itself and go unnoticed in our cells, thus avoiding these acting against the infectious bacteria.
