But many have also mastered a different sort of target that allows them to wield control over the rest of the cell without venturing into the cytoplasm: namely, lipid membranes. Some bacteria launch a ...

In biology textbooks, the endoplasmic reticulum is often portrayed as a distinct, compact organelle near the nucleus, and is ...

Light and electron microscopy have distinct limitations. Light microscopy makes it difficult to resolve smaller and smaller ...

In the early 2010s, it was shown that the naturally formed nanostructure on the wings of cicada and dragonfly wings can resist bacterial contamination. The structures damage the cell membrane of ...

First observed in a common lab bacterium only 14 years ago, bacterial nanotubes are structures made of cell membrane that allow nutrients and resources to flow between two or more cells. The ...

Current optical and electron microscopy imaging techniques are not suited for measuring the dynamic characteristics of living microorganisms at tiny scales due to complex sample preparation methods or ...

Compared to viruses, bacteria are larger and have a more sophisticated structure that includes a cytoplasm, membrane, cell wall, and genetic material. Because they reproduce via binary fission ...

Scientists develop self-propelling nanoparticles that can physically pierce and eliminate drug-resistant bacteria in eye infections, showing success in initial animal studies.

Yersinia bacteria use a membrane protein called Invasin to attach to human cells—a clever trick that the researchers decided to repurpose. "We started to think out of the box and try something ...

The endoplasmic reticulum (ER) is a crucial organelle present in all eukaryotic cells, including human cells. The ER plays a ...

Researchers engineer bacteria to produce hydrogen fuel from sunlight, potentially revolutionizing green hydrogen production.
