However, observations carried out with a phase-contrast microscope on isolated living liver cells from animals kept in hypoxia indicate that vacuoles are not visible in non-fixed, unstained cells.

Plants droop and shed their leaves when parched, but with a splash of water, their stems regain strength and their leaves ...

The management of Leishmania donova ni (LD), responsible for fatal visceral leishmaniasis (VL), faces increasing challenges due to rising drug-unresponsiveness, leading to increasing treatment ...

A team led by UT Southwestern Medical Center researchers has identified a key mechanism responsible for endosomal recycling ...

Collagen, the body's most abundant protein, has long been viewed as a predictable structural component of tissues. However, a new study challenges that notion, revealing an unexpected confirmation in ...

Virginia Tech neuroscientists have uncovered a mitochondrial process that supports the brain cells critical for learning, ...

Electron microscopy uses a beam of electrons to illuminate a sample and achieve much higher spatial resolution than light microscopy. Transmission electron microscopy generates an image of the ...

By reexamining 3D images used to map the connections between brain cells, researchers are uncovering new information about a small, elusive, and often overlooked cellular appendage.

Natural resistance-associated macrophage proteins (NRAMPs) have been shown to transport a wide range of divalent metal ions, such as manganese (Mn), cadmium (Cd), and Iron (Fe). Iron is an essential ...

Guard cells are pairs of epidermal cells that control gas diffusion by regulating the opening and closure of stomatal pores. Guard cells, like other types of plant cells, are surrounded by a ...
