As newborn neurons make their way through the developing brain, they must squeeze through incredibly tight spaces to reach their final destinations. Researchers discovered that this physical journey ...

Brain cells receive sensory inputs from the outside world and send signals throughout the body telling organs and muscles what to do. Although neurons comprise only 10% of brain cells, their ...

As direct descendants of ancient bacteria, mitochondria have always been a little alien. Now a study shows that mitochondria are possibly even stranger than we thought. The study, titled "Somatic ...

For decades, large stretches of human DNA were dismissed as "junk" and considered to serve no real purpose. In a new study published in Cell Genomics, researchers at Lund University in Sweden show ...

Newborn nerve cells must squeeze through crowded, narrow spaces—through dense tissue, past other cells, and between fibers—to reach the areas where they form neural circuits in the brain cortex. In a ...

We have been taught that we each have our one unique DNA, a genetic code that is a fixed and sacrosanct definition of our being, identical copies housed in each cell of our bodies. When we spit in a ...
