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 ...

Animals display an extraordinary array of structural adaptations that are intimately linked to their functional capacities. From the microscopic organisation of tissues and cells to the macroscopic ...

Researchers have developed a human intestinal cell model that closely mimics the structure and function of the human gut, enabling more precise prediction of drug-induced gastrointestinal toxicity ...

Energy-making chloroplasts from algae have been inserted into hamster cells, enabling the cells to photosynthesize light, according to new research in Japan. It was previously thought that combining ...

Researchers have developed artificial cell-like structures using inorganic matter that autonomously ingest, process, and push out material - recreating an essential function of living cells. Their ...

The Saint Louis University Biology Department offers courses with hands-on learning opportunities from cellular structures to fish, birds, reptiles and mammals. Content below is provided by SLU ...

More than a billion years ago a hungry cell devoured a tiny blue-green alga. But instead of the former simply digesting the latter, the duo struck a remarkable evolutionary deal. Now scientists are ...

Under stress, animal cells pair inactive ribosomes into RNA-linked disomes. A ribosomal RNA “kissing loop” joins them, protecting ribosomes and reducing protein synthesis to conserve energy.<br /> ...
