Screw cancer: Microneedle sticks it to cancer tissue

A drug-loaded microrobotic needle effectively targets and remains attached to cancerous tissue in lab experiments without needing continuous application of a magnetic field, allowing more precise drug delivery. The details ...

Blood flows could be more turbulent than previously expected

Blood flow in the human body is generally assumed to be smooth due to its low speed and high viscosity. Unsteadiness in blood flow is linked to various cardiovascular diseases and has been shown to promote dysfunction and ...

Images of 'invisible' holes on cells may jumpstart research

High blood pressure, inflammation, and the sensation of pain may rely in part on tiny holes on the surface of cells, called pores. Living cells react to the environment, often by allowing water and other molecules to pass ...

Researchers lay foundation for next generation aortic grafts

A new study by researchers at McGill University has measured the dynamic physical properties of the human aorta, laying the foundation for the development of grafts capable of mimicking the native behaviour of the human body's ...

Reducing the risk of blood clots in artificial heart valves

Most people are familiar with turbulence in aviation: certain wind conditions cause a bumpy passenger flight. But even within human blood vessels, blood flow can be turbulent. Turbulence can appear when blood flows along ...

Deadly 'superbugs' destroyed by molecular drills

Molecular drills have gained the ability to target and destroy deadly bacteria that have evolved resistance to nearly all antibiotics. In some cases, the drills make the antibiotics effective once again.

Blood flow

Blood flow is the flow of blood in the cardiovascular system.

It can be calculated by dividing the vascular resistance into the pressure gradient.
