Every passing second, RBCs in the blood carry oxygen from the lungs through a network of microscopic channels and release it into tissues, where it is used to produce energy. The process consists of ...

The brain relies on real-time delivery of oxygen and nutrients through its microvasculature, which threads through neural tissue like electrical wires. While modern imaging technologies allow ...

Until today, skin, brain, and all tissues of the human body were difficult to observe in detail with an optical microscope, since the contrast in the image was hindered by the high density of their ...

Stanford Medicine researchers have developed a blood test capable of detecting cancers, the ways cancer resists treatments and tissue injury caused by non-cancerous conditions. The new test analyzes ...

In a recent study, researchers have unveiled the presence of peculiar microscopic structures in the blood of Long COVID patients. These formations, reported on November 13, 2025, are described as ...

Researchers at the University of Nottingham have created an endoscopic device that can 3D image the stiffness of individual biological cells and complex organisms, a discovery that could help doctors ...

Imagine building a traffic surveillance camera that could detect trouble-making cells speeding around in your brain before their cellular gang could commit "crimes." Most importantly, this camera ...

Schematic of how individual red blood cells (RBCs) carry oxygen through capillaries to oxygenate tissues. The team found that RBCs can regulate how much oxygen is released in tissues, wherein ...
