Small proteins play big role in cellular energy balance

Scientists at Duke-NUS Medical School have discovered new molecular details of how cells ensure that their energy supply is adjusted to meet energy demand. Their study, carried out in collaboration with researchers at the ...

Another step toward synthetic cells

Building functional synthetic cells from the bottom-up is an ongoing effort of scientists around the globe. Their use in studying cellular mechanisms in a highly controlled and pre-defined setting creates great value for ...

New technology solves mystery of respiration in Tetrahymena

Tetrahymena, a tiny single celled-organism, turns out to be hiding a surprising secret: it's doing respiration—using oxygen to generate cellular energy—differently from other organisms such as plants, animals or yeasts. ...

How some tissues can 'breathe' without oxygen

Humans need oxygen molecules for a process called cellular respiration, which takes place in our cells' mitochondria. Through a series of reactions called the electron transport chain, electrons are passed along in a sort ...

A novel form of cellular logistics

Biophysicists from Ludwig-Maximilians-Universitaet (LMU) in Munich have shown that a phenomenon known as diffusiophoresis, which can lead to a directed particle transport, can occur in biological systems.

Biologists shed light on how cells move resources

Florida State University researchers have new insight into the tiny packages that cells use to move molecules, a structure that is key to cellular metabolism, drug delivery and more.

Intracellular transport in 3-D

Ludwig Maximilian University researchers have visualized the complex interplay between protein synthesis, transport and modification.

Islands in yeast membrane revealed by extreme microscopy

University of Groningen microbiologists have visualized tiny islands in the cell membrane of baker's yeast. These membrane compartments appear to store transport proteins before use. The scientists observed that these proteins ...

Researchers reveal jamming in cellular motor protein traffic

To keep a cell alive, molecular motor proteins constantly transport building blocks and waste across the cell, along its biopolymer network. Because of the high density of these proteins, jamming effects are believed to affect ...
