Team identifies proton pathway in photosynthesis

(Phys.org) —A Purdue University-led team has revealed the proton transfer pathway responsible for a majority of energy storage in photosynthesis. Through photosynthesis, plants, algae and bacteria convert sunlight, carbon ...

Cell morphology shapes protein patterns

Precise control of thedistribution of specific proteins is essential for many biological processes. An LMU team has now described a new model for intracellular pattern formation. Here, the shape of the cell itself plays a ...

New system to improve DNA sequencing

(Phys.org) —A sensing system developed at Cambridge is being commercialised in the UK for use in rapid, low-cost DNA sequencing, which would make the prediction and diagnosis of disease more efficient, and individualised ...

Nanoneedle is small in size, but huge in applications

(PhysOrg.com) -- Researchers at the University of Illinois have developed a membrane-penetrating nanoneedle for the targeted delivery of one or more molecules into the cytoplasm or the nucleus of living cells. In addition ...

Researchers uncover new function for cell master regulator

(PhysOrg.com) -- TORC1 is a master regulator in cells, playing a key role in such diverse processes as gene expression and protein synthesis. While previous studies have described the role that TORC1 plays in these processes, ...

Human white blood cells use molecular paddles to swim

Human white blood cells, known as leukocytes, swim using a newly described mechanism called molecular paddling, researchers report in the September 15th issue of Biophysical Journal. This microswimming mechanism could explain ...

Cell: Protein folding via charge zippers

Membrane proteins are the "molecular machines" in biological cell envelopes. They control diverse processes, such as the transport of molecules across the lipid membrane, signal transduction, and photosynthesis. Their shape, ...
