A hybrid microscope allows scientists to simultaneously image the full 3D orientation and position of an ensemble of molecules, such as labeled proteins inside cells. The microscope combines polarized ...

Researchers have discovered a fundamental mechanism that affects the size of the pupil, namely our breathing. The study shows that the pupil is smallest during inhalation and largest during exhalation ...

Researchers at Karolinska Institutet in Sweden have discovered a fundamental mechanism that affects the size of the pupil, namely our breathing.

Photonics researchers from Tampere University, Finland, and Kastler-Brossel Laboratory, France, have demonstrated how ...

Neurons are cells in the body that are responsible for transmitting ... Interneurons have a multipolar structure that allows them to receive multiple signals and then send a unified command to another ...

Tubulins are a conserved superfamily of proteins that are important in the structure and function of the microtubule cytoskeleton. We have characterized in vertebrates the final member of the tubulin ...

Recent research reveals how mitochondria act as reservoirs for NAD, supporting cells during increased demand. This insight opens doors to therapeutic strategies for mitigating aging and related ...

Cilia are outgrowths ... in signalling between cells. Cilia assembly relies on cargo trains that move bidirectionally on separate tubules of the ciliary microtubular structure, preventing traffic ...

But filopodia can also wreak havoc: metastatic cancer cells use them to invade new regions of the body. Filopodia are composed of hexagonal bundles of proteins that give them structure and strength.
