People need to sleep, and sleep deprivation can cause many changes in the brain. But we have a poor understanding of why sleep is so crucial. New research has examined a fruit fly model to assess how ...

Mitochondria are essential for cell survival, repair, and adaptation. Not only do they generate most of the energy needed during a cell's life, but they also regulate cell death, calcium balance, and ...

Scientists in the laboratory of Navdeep Chandel, Ph.D., the David W. Cugell, MD, Professor of Medicine in the Division of Pulmonary and Critical Care, have discovered how mitochondria influence the ...

Mitochondria organelles came from primordial bacterial endosymbionts and still preserve distinct genes for important functions like making ATP. To speed the emerging therapeutic research into the ...

Many of us remember from high school biology class that mitochondria are the cell's "power plants." These small kidney-bean-shaped structures are what convert nutrients from food into ATP—the cell's ...

The mitochondria, the powerhouse of the cell, plays a surprising role in diet and health since its function in energy production directly influences body metabolism, that are also involved in aging ...

A new study finds that mitochondria in our brain cells frequently fling their DNA into the cells' nucleus, where the mitochondrial DNA integrates into chromosomes, possibly causing harm. As direct ...

Researchers have developed experimental drugs that encourage the mitochondria in our cells to work a little harder and burn more calories. The findings could open the door to new treatments for ...

Infertility affects around 48 million couples worldwide and can have various causes. In mammals, including humans, eggs are produced in the ovary. When this process goes wrong, it can lead to female ...

Samantha J. Krysa is in the Department of Pathology and Immunology, Washington University School of Medicine, St. Louis, Missouri 63110, USA. Research over the past 20 years has revealed that many ...

In a popular Indian parable, a few blind men interact with an elephant for the first time and imagine what it looks like. The man touching the tusk may describe the elephant as a spear, while the ...

Scientists have found DNA in the nucleus of brain cells, where it shouldn’t be. Bits of genes that typically reside in mitochondria insert themselves at unexpectedly high rates into brain cells’ ...
