Understanding how our cells clean up as we age

June 2, 2026

Our bodies slow down in many ways as we get older, and that includes how well our cells can clean themselves. Inside nearly every cell, there’s a cleanup crew called autophagy. That’s basically a system where cells break down and recycle damaged parts, like old batteries or broken appliances. It’s l

Fasting: A Simple Way to Boost Health and Longevity

February 15, 2026

Skipping meals can spark a powerful cleanup inside the body. When food is absent, cells start to recycle their damaged parts in a process called autophagy. This helps protect the brain from diseases such as Alzheimer’s and Parkinson’s. The body also switches its fuel source. After about a day witho

How Oysters Fight Off Germs: A Tiny but Mighty Defense System

November 29, 2025

In the world of tiny creatures, the Pacific oyster, Crassostrea gigas, has a clever way to protect itself from harmful microbes. It uses a special protein called CgC3 to tag and trap invaders. This protein can stick to various sugars and microbes, acting like a sticky note that marks the bad guys fo

How Cells Fight Back: The Hidden Battle Inside Glioblastoma

June 30, 2025

Inside the brain, there's a sneaky fight happening. Glioblastoma, a tough type of brain cancer, is always finding ways to survive. Scientists have spotted a clever trick it uses. A tiny helper inside cells, called SH3GLB1, is part of this trick. It helps cells clean up and recycle their own parts. T

How Tiny Parasites Trick Our Cells to Help Them Grow

May 30, 2025

Microsporidia are tiny parasites that must live inside other cells to survive. They have a knack for manipulating the host's cellular processes to their advantage. One such process is autophagy, which is like the cell's recycling system. It usually helps the host cell get rid of unwanted stuff, in

Mitochondria's Double Trouble: Tracking NAD(P)H and pH

April 30, 2025

Mitochondria are the powerhouses of cells, but they can also cause trouble when things go wrong. Two key factors that can indicate mitochondrial issues are levels of NAD(P)H and pH. These factors are closely linked to a process called mitochondrial autophagy, which is the cell's way of cleaning up d

How Cells Fight Back Against Salmonella

April 3, 2025

The human body is a battleground. Every day, cells face off against invading bacteria. One such invader is Salmonella, a sneaky pathogen that can slip into the cytoplasm of epithelial cells. When this happens, the cell's defense system kicks into gear. This system is called xenophagy, a type of auto

Plants Fight Back: How ATG6 and NPR1 Team Up to Boost Immunity

March 5, 2025

Plants have their own ways of staying healthy. Two key players in this defense system are ATG6 and NPR1. ATG6 is a gene linked to a process called autophagy, which helps plants break down and recycle their own components. NPR1, on the other hand, is a master regulator that coordinates the plant's im

The Hidden Role of Cellular Cleanup in Keeping DNA Safe

February 2, 2025

Imagine tiny factories inside our body cells, constantly making proteins and repair kits to stay healthy. We all know that these factories in our cells produce and break down proteins. There are different ways to clean out old or damaged proteins. One of those cle
