In eukaryotic cells, which are found in complex organisms including humans, little membrane-bound organelles carry out various functions. It's been suggested that these organelles, which all have ...

Organelles – the bits and pieces of RNA and protein within a cell – play important roles in human health and disease, such as maintaining homeostasis, regulating growth and aging, and generating ...

Cells are filled with membrane-bound organelles like the nucleus, mitochondria and endoplasmic reticula. Over the years, scientists have made much progress in understanding the biomolecular details of ...

The ability to make membrane-bound organelles is a defining characteristic of eukaryotic cells — cells that constitute the bodies of all animals, plants and fungi on Earth. Membranes create enclosures ...

Stress is a normal response to physical and emotional stimuli, particularly when people face changes in their lives. Though it’s a normal feeling, long-term stress may lead to a range of health ...

Plants' ability to sense light and temperature, and their ability to adapt to climate change, hinges on free-forming structures in their cells whose function was, until now, a mystery. Researchers ...

Unlike our organs, cell organelles such as mitochondria are not fixed in place, but when, where, how, and why organelles move remain unclear. Research ...

One of the many challenges of medical science is creating antibiotics that kill infectious diseases but leave useful bacteria alone. Even if a treatment is effective at neutralizing the intruder, its ...
