How did this process of self-eating evolve? How is it controlled by the cell? Today, research on autophagy is a growing field with increasing prominence because understanding the basic mechanisms ...

The term 'autophagy' was chosen to distinguish the lysosomal degradation, or 'eating' (phagy), of part of the cell's self (auto) from the breakdown of extracellular material (heterophagy).

Lysosomes are membrane-bound organelles in cells that act as recycling centers—breaking down waste materials, damaged ...

High rates of autophagy can even help to regulate uncontrolled cell growth, i.e. cancer, King says. Again, research into the potential perks of cold plunges is ongoing. So, it's entirely possible ...

Daniela Hernandez extends her health and science reporting to cover a variety of relevant subjects from Covid-19 to climate change.

The Overholtzer lab studies mechanisms of nutrient sensing and cellular responses to nutrient starvation, including the nutrient recycling pathway autophagy, scavenging pathways such as ...

These findings suggest that people with gum disease, especially those infected with P. gingivalis producing gingipain, may be at greater risk of serious complications if they suffer a heart attack.

A new research paper was published in Aging (Aging-US) on March 18, 2025, in Volume 17, Issue 3, titled “Mitochondrial oxidative stress or decreased autophagy in osteoblast lineage cells is not ...

A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their ...
