Message in a bottle: Info-rich bubbles respond to antibiotics

Once regarded as merely cast-off waste products of cellular life, bacterial membrane vesicles (MVs) have since become an exciting new avenue of research, due to the wealth of biological information they carry to other bacteria ...

Not as simple as thought: How bacteria form membrane vesicles

Researchers from the University of Tsukuba identified a novel mechanism by which bacteria form membrane vesicles, which bacteria employ to communicate with each other or to defend themselves against antibiotics. By studying ...

Researchers create artificial cell organelles for biotechnology

Biotechnologists have been attempting to reprogram natural cell organelles for other processes for some time—with mixed results, since the laboratory equipment is specialized on the function of organelles. Dr. Joanna Tripp, ...

How local forces deform the lipid membranes

ETH Zurich researchers have been able to show why biological cells can take on such an astonishing variety of shapes: it has to do with how the number and strength of local forces acting on the cell membrane from within. ...

Researchers study a novel type of extracellular vesicles

Researchers from Sechenov University and the University of Pittsburgh compared the properties of two groups of extracellular vesicles. Either present in a liquid phase or attached to the fibres of the extracellular matrix, ...

Kiss and run: How cells sort and recycle their components

What can be reused and what can be disposed of? Cells also face this tricky task. Researchers from the Biozentrum of the University of Basel have now discovered a cellular machine, called FERARI, that sorts out usable proteins ...

Black nanoparticles slow the growth of tumors

The dark skin pigment melanin protects against the sun's damaging rays by absorbing light energy and converting it to heat. This could make it a very effective tool in tumor diagnosis and treatment, as demonstrated by a team ...

Nano-bio-computing lipid nanotablet

Nanoparticles can be used as substrates for computation, with algorithmic and autonomous control of their unique properties. However, scalable architecture to form nanoparticle-based computing systems is lacking at present. ...

Highly sensitive method to detect potential cancer biomarker

Exosomes regulate intercellular communication in cancers, and are drawing attention as a potential cancer biomarker. A Japanese research group has developed a highly sensitive method for detecting these exosomes that could ...
