The new science shows that the best way to protect your mind as you age is to move enough, but not too much. Studies that followed older people for almost a decade found that those who walked between 5, 000 and 7, 500 steps each day had slower buildup of the tau protein that causes Alzheimer’s. E
In the world of tiny worms, scientists found something interesting. They wanted to see if poison affects the babies of parents who were exposed to it. They used a special worm called Caenorhabditis elegans for their experiments. First, they gave the worms different amounts of a poison called roteno
Scientists discovered that tiny fragments from mouse mitochondria can make the body’s defense cells work against tumors. These fragments, called formyl peptides, are normally produced when bacteria or mitochondria break down proteins. Researchers first identified five specific mouse peptides t
Microplastics are everywhere. They're in our water, our food, and even the air we breathe. But what happens when these tiny plastic bits get into our bodies? A recent study looked at how different types of microplastics affect brain cells, especially the ones that protect our nervous system. The st
Chickens are what they eat, but how exactly does their food impact their growth and energy? A recent investigation dug into this question. Researchers were curious about how tweaking the energy and protein content in chicken feed affects their tiny powerhouses, known as mitochondria. They focused on
Cancer cells are known for their ability to adapt and survive in tough conditions. One of the biggest challenges they face is living in an acidic environment. This acidity is a result of the tumor's own metabolism and can be harmful to the cells. However, cancer cells have found a way to use this ac
Alzheimer's disease is a complex puzzle. One key piece? Tiny powerhouses in our cells called mitochondria. These little guys usually help cells stay alive and healthy. But in Alzheimer's, they're not working right. Why? Because calcium, a crucial messenger in cells, is out of balance. Calcium is li
Muscle injuries often leave people wondering whether to rest or engage in rehabilitative activities. While activity can speed up recovery, it can also cause further damage if done too soon. Scientists have been exploring ways to enhance muscle healing, and one promising method is mitochondria transp
Breast cancer is a tough opponent. It's smart, sneaky, and hard to beat. But scientists are fighting back with a clever new weapon: tiny nanoparticles that can target cancer cells and their powerhouses, the mitochondria. These nanoparticles are like tiny delivery trucks. They carry two special carg
Aging is not just about wearing out like an old machine. It's more like a computer losing its software, not the hardware. Dr. David Sinclair, a Harvard geneticist, says that as we get older, the instructions that tell our cells what to do get mixed up. This is called the "information theory of aging
