Physics solves blood vessel mystery
Experiments on the effect have been performed by introducing a compound called angiotensin II into the blood stream of a rat. This compound narrows the diameter of the blood vessels, which increases t...
New tools for brain surgery
Unlike other instruments, the invention does not require any sharp blades or cumbersome power sources (such as those needed for ultrasound devices) in the operating theatre. Instead, a small paddle ro...
Complexity holds thekey to predicting epileptic seizures
In a process called electroencephalogram (EEG), brain activity is measured by strapping electrodes to the scalp. The electrodes record weak electrical waves produced from different parts of the brain ...
Blood tests without needles
Recognising blood cells presents a big challenge for automated counting systems. As blood flows through veins, the cells are deformed in the direction of blood flow. Blood also contains a lot of other...
