Scientists have discovered a mysterious new structure lurking inside every human cell. These tiny structures, dubbed hemifusomes, are just 200 to 400 nanometres in diameter. To put that into ...

Cells have an internal skeleton that maintains their structure and also drives their movement. Known as the cytoskeleton, ...

In 2015, researchers at UC San Francisco found a structure inside of tumor cells that biologists had never seen before. Even more surprising, a closer examination of the structure revealed that it ...

Microfilaments made using a new 3D printing method (gray) form a structure that plant and animal cells (in color) can adhere to. The shapes formed by the filaments determine the uniform cell shapes. A ...

More than 1.5 billion years ago, a momentous thing happened: Two small, primitive cells became one. Perhaps more than any event—barring the origin of life itself—this merger radically changed the ...

The endoplasmic reticulum (ER) forms tight membrane contact sites (MCSs) with several organelles in animal cells and yeast. The function of MCSs between the ER and mitochondria and endosomes are ...

Stereoblastic embryos from the Doushantuo Formation of China exhibit occasional asynchronous cell division, with diminishing blastomere volume as cleavage proceeded. Asynchronous cell division is ...

Biomedical research typically follows a familiar path: developing treatments that block, enhance or mutate certain signaling ...

Retroviruses are viruses that have evolved the ability to write their genetic code into a cell's own DNA. The most ancient ...

Chloroplasts, the parts of cells that allow plants and algae to photosynthesize, are thought to have originated more than 1 billion years ago, when photosynthetic cyanobacteria lived symbiotically ...
