Inside mitochondria and their fascinating genome

Mitochondria are present in all eukaryotic cells: in our cells, in mammalian cells, in the cells of plants and even of fungi. Mitochondria produce energy for cells to function as multicellular organisms, and are known as ...

Neandertals have adopted male sex chromosome from modern humans

In 1997, the very first Neandertal DNA sequence—just a small part of the mitochondrial genome—was determined from an individual discovered in the Neander Valley, Germany, in 1856. Since then, improvements in molecular ...

How cGAS enzyme is kept bottled up

In higher organisms, detection of DNA in the cytoplasm triggers an immune reaction. The enzyme that senses "misplaced" DNA is also found in the nucleus, but nuclear DNA has no such effect. LMU researchers now report why that ...

A ribosome odyssey in mitochondria

Proteins make life and are made by ribosomes. In mitochondria, the repertoire of the mitoribosomal architectures turns out to be much more diverse than previously thought.

Becoming a nerve cell: Timing is of the essence

Mitochondria are small organelles that provide the energy critical for each cell in our body, in particular, in the energy-demanding brain. In this week's edition of Science, a Belgian team of researchers led by Pierre Vanderhaeghen ...

Imaging method highlights new role for cellular 'skeleton' protein

While your skeleton helps your body to move, fine skeleton-like filaments within your cells likewise help cellular structures to move. Now, Salk researchers have developed a new imaging method that lets them monitor a small ...
