It seems that more and more amazing discoveries are being made in the scientific world. Check out the latest one below.

New tool uses ultrasound tornado to break down blood clots 

A novel method utilizing “vortex ultrasound,” similar to an ultrasonic tornado, has been created by researchers to disintegrate blood clots in the brain. This groundbreaking technique proved to be faster than current methods for removing clots formed in a laboratory model of cerebral venous sinus thrombosis (CVST).

“Our previous work looked at various techniques that use ultrasound to eliminate blood clots using what are essentially forward-facing waves,” says Xiaoning Jiang, co-corresponding author of a paper on the work. “Our new work uses vortex ultrasound, where the ultrasound waves have a helical wavefront.

“In other words, the ultrasound is swirling as it moves forward,” says Jiang, who is the Dean F. Duncan Professor of Mechanical and Aerospace Engineering at North Carolina State University.

“Based on our in vitro testing, this approach eliminates blood clots more quickly than existing techniques, largely because of the shear stress induced by the vortex wave.”

“The fact that our new technique works quickly is important because CVST clots increase pressure on blood vessels in the brain,” says Chengzhi Shi, co-corresponding author of the work and an assistant professor of mechanical engineering at Georgia Tech. “This increases the risk of a hemorrhage in the brain, which can be catastrophic for patients.

“Existing techniques rely in large part on interventions that dissolve the blood clot. But this is a time-consuming process. Our approach has the potential to address these clots more quickly, reducing risk for patients.”

Strong connection between electromagnetism, blood flow and coagulation 

The field of hemodynamics is filled with many unknowns and uncertainties. The amount of effort required to move blood through the systemic circulation is greater than the effort exerted by the left ventricle. As a result, blood experiences increased resistance between heartbeats, which can be observed through changes in the Womersley number and the rhythm of the accompanying electrocardiogram (ECG). Coagulation is heavily influenced by viscoelastic transformation. Check out our previous article in order to learn more details.
