These mechanisms help keep heat in or carry it to the skin’s surface, causing muscle contractions and shivering. Your heart rate can increase when your body works harder to keep its typical ...

I have always had a soft spot for the Surface Pro X. It was the thinner ... This time around, it’s warming my heart instead of breaking it, thanks to a redesign of the entire tablet and the ...

The heart consists of 4 chambers--2 atria (upper chambers) and 2 ventricles (lower chambers). Blood passes through a valve as it leaves each chamber of the heart. The valves prevent the backward flow ...

Electrical signals control the beating of your heart. They tell your heart muscle when to contract, a process known as conduction. The normal timing of heartbeats is generated in the upper chamber of ...

A recent study by lead researcher Peng Zheng developed a chip surface that utilizes the SERS technique to reduce the time for heart attack diagnoses. SERS relies on light to identify molecular ...

The heart rate measures the number of times per minute that the heart contracts or beats. Most adults have a target resting heart rate of 60 to 100 beats per minute. A healthy heart supplies the ...

A tiny chip with a unique surface can accurately detect the blood biomarkers of a heart attack within minutes, a fraction of the time taken by current methods, even if they’re at very low ...
