Discovery of DNA repair mechanism advances understanding of how human cells stay healthy

Researchers at the University of Toronto have discovered a DNA repair mechanism that advances understanding of how human cells stay healthy, and which could lead to new treatments for cancer and premature aging.

Bacterial cell division: Rethinking size regulation

When a single bacterial cell divides into two during periods of rapid growth, it doesn't split in half once it reaches a predetermined size. Instead, data has shown, a cell will divide once it has added a certain amount of mass.

Machine learning reveals age-related decline in stemness across human tissues

A new research paper was published on the cover of Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 16, Issue 7, entitled, "Evidence of a pan-tissue decline in stemness during human aging."

First comprehensive atlas sheds new light on processes underlying age-related muscle changes

How muscle changes with aging, and tries to fight its effects, is now better understood at the cellular and molecular level with the first comprehensive atlas of aging muscles in humans.

Proteasomes: Expanding roles beyond cellular waste management

The typical job of the proteasome, the garbage disposal of the cell, is to grind down proteins into smaller bits and recycle some of those bits and parts.

Research sheds light on post-sepsis immune suppression mechanism

Severe sepsis from bacterial or viral infections can be life-threatening and even people recovering from severe sepsis may experience long-lasting effects on the immune system, making them more susceptible to recurrent infections.

Unraveling the mysteries of gastro-esophageal junction development

The transition from the esophagus to the stomach is a delicate region from a medical point of view, often associated with pathological disorders leading to cancer.

Nanopore sequencing unveils novel telomere length patterns

We depend on our cells being able to divide and multiply, whether it's to replace sunburnt skin or replenish our blood supply and recover from injury.

Understanding the mechanisms behind embryonic diapause in hungry mouse mums

It's challenging to sustain a pregnancy when food is short, or conditions are otherwise tough. That's why many mammalian embryos can postpone their growth to get through periods of environmental stress and then re-enter development when conditions improve.
