The human body has always been crowded with microscopic passengers, from bacteria to viruses and fungi. Over the past two years, however, researchers have started to realize that this familiar cast ...

Mitochondria are essential for cell survival, repair, and adaptation. Not only do they generate most of the energy needed ...

Let’s start with a quick biology refresher: Mitochondria are the powerhouse of the cell. They convert the food we eat into ...

A tiny elephant establishes a new stomping ground for 3-D printing: inside cells. For the first time, scientists have 3-D printed objects within living cells, including a 10-micrometer long elephant ...

Researchers at the Francis Crick Institute have shown that the 'pacemaker' controlling yeast cell division lies inside the nucleus rather than outside it, as previously thought. Having the pacemaker ...

Experiments reveal that unsaturated lipid membranes promote vesicle fusion and DNA retention during freeze–thaw cycles, ...

It’s a familiar image, reprinted in countless biology textbooks: an illustration of a typical cell, halved like a grapefruit to reveal its innards. Strands of endoplasmic reticulum encircle a nucleus ...

A cell nucleus reconstituted in vitro in Xenopus laevis (African clawed frog) egg extract. Left image shows a fluorescence image where DNA has been stained and right image shows a density map of the ...

Life’s fundamental structure is the cell, and so the main things that a cell does — processing biomolecules, growing, replicating its genetic material and producing a new body — are considered ...

In many submerged regions, murky mud shelters strange life-forms that seem to be the key to one of the biggest mysteries of life on Earth. These creatures belong to a domain of life called the archaea ...

Mitochondrial transplantation is an emerging technique aimed at restoring cellular energy production in diseases marked by ...
