For a few weeks in 2017, Wanda Kukulski found herself binge-watching an unusual kind of film: videos of the insides of cells. They were made using a technique called cryo-electron tomography (cryo-ET) ...

Around 1.7 billion years ago, eukaryotes—the building blocks of complex life—first appeared on Earth, and now scientists have ...

All modern multicellular life — all life that any of us regularly see — is made of cells with a knack for compartmentalization. Recent discoveries are revealing how the first eukaryote got its start.

The origin of the nucleus remains hotly debated among scientists, but new imaging and genomic data are shedding light on this billion-year-old mystery.

On the basis of their gene content and aspects of their cellular physiology, prokaryotes are classified into two domains: Bacteria and Archaea. Their commmon ancestor is known as the 'last universal ...

Researchers have succeeded in cultivating a special archaeon and characterizing it more precisely using microscopic methods. This member of the Asgard archaea exhibits unique cellular characteristics ...

A research team from the Faculty of Science, Charles University in Prague has discovered Solarion arienae, an extremely rare and morphologically unique unicellular eukaryote that sheds new light on ...

The molecular building blocks that make up the cells of humans, animals and plants so sophisticated appear to be older than scientists previously ...

New confocal reflectance interferometric microscope enables scientists to probe nuclear membrane mechanics within intact cells in a label-free fashion Nuclear mechanics is known to play a key role in ...

Molecular biology has something in common with kite-flying competitions. At the latter, all eyes are on the colorful, elaborate, wildly kinetic constructions darting through the sky. Nobody looks at ...
