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 ...

During a heart attack, heart muscle cells die and are replaced by scar tissue. This delays the electrical conduction in the heart and favours the onset of cardiac arrhythmia. To reduce this ...

No one can live without a heart pumping blood to the rest of the body. New research from the University of Missouri School of ...

This study explores the use of polarized second-harmonic generation (pSHG) to investigate myosin conformation in the relaxed state, differentiating between the actin-available, disordered (ON) state ...

Quick facts about the heart What the heart is made of: Heart muscle tissue, also called cardiac muscle tissue What makes the heart beat: Electrical signals Average resting heart rate: 60 to 100 ...

The ability to detect and characterize microscopic structural changes in tissue opens new possibilities for early cancer detection to improve patient outcomes.

5. Cardiac Muscle Inefficiency Aging causes changes in your heart tissue, including a decrease in cardiomyocytes (heart muscle cells), reduced elasticity of blood vessels, increased stiffness of the ...

This technique, called volumetric DNA microscopy, creates a 3D image of an entire organism from the inside out, giving scientists an unprecedented view of genetic sequences and where they are ...

Now, MIT engineers have taken a major step toward developing robots that replace rigid gears with something much softer – almost like real, living muscle tissue. In ...

A new hybrid microscope for the first time allows scientists to simultaneously image the full 3D orientation and position of an ensemble of molecules, such as labeled proteins inside cells.
