@drbahaadmourInside the Heart | Blood Leaves and Remains 🔄🫀 ────────── Your heart does not empty completely with every beat. 🔬 The left ventricular ejection fraction, or LVEF, measures how much blood the left ventricle pumps out during contraction. For example, an LVEF of 64% means the left ventricle ejects 64% of the blood volume it contains at the end of filling, while about 36% remains inside before the next heartbeat refills it. A value of 64% is within the usual normal range. Blood then

What’s this little hand gesture Catholics do during Mass? Well, the timing is important. Right after the Gospel is announced, we trace a small cross onto our forehead, lips, and heart. We do this so that we may contemplate the Gospel in our mind, proclaim it with our mouth, and nurture it in our heart. After this, a passage from the life of Christ is read as the congregation stands in attention. As I’ve said before with the bells and the incense and the vestments and the colors, every part of th

Euclid captures the Milky Way’s crowded heart ✨ This is the largest high-resolution photo ever made of our Milky Way galaxy’s centre in visible light. It was taken on 23 March 2025 by our Euclid space telescope. Packed with more than 60 million stars, this image opens the door for scientists to confirm the existence of any exoplanet found in this region and measure its mass using tiny changes in starlight over time.
