Music of the Spheres – NASA

[0:00] Narrator:Did you know that the Earth rings like a bell? (bell tone) [0:05]When there’s an earthquake, vibrations travel through rock, just as vibrations move through a bell to create a ringing sound. We know our planet rings like this because of seismometers, instruments that measure the vibrations of the Earth moving beneath our feet. We don’t hear the Earth ringing because these rock vibrations, called seismic waves, have a frequency spectrum below one Hertz. The lowest frequency human ears typically can hear is 20 Hertz. By speeding up seismic waves hundreds or even thousands of times, you can…

Archaeologists uncover a 2,000-year-old crop in the Canary Islands

Scientists decoded DNA from millennia-old lentils preserved in volcanic rock silos on Gran Canaria. The findings show that today’s Canary Island lentils largely descend from varieties brought from North Africa around the 200s. These crops survived cultural upheavals because they were so well-suited to the islands’ harsh climate. Their long-standing resilience could make them valuable for future agriculture. Source link

Mayo Clinic researchers use AI and genetics to identify early signs of a rare, life-threatening heart condition

ROCHESTER, Minn. — At Mayo Clinic, cardiologists Peter Noseworthy, M.D., and John Giudicessi, M.D., Ph.D., are uncovering the earliest signs of a genetic heart condition that often strikes without warning. Their work shows that early detection, and even prevention, may be possible long before symptoms appear.  The condition, arrhythmogenic right ventricular cardiomyopathy, weakens the molecules that hold heart cells together. As those bonds deteriorate, healthy muscle is replaced with scar tissue and fat, leaving the heart weaker.   The disease often advances silently. Sometimes the first sign is when a person suddenly collapses during exercise. For many, a diagnosis comes only after the heart is already damaged. Detecting it earlier could spare patients from heart failure, the need for a transplant or sudden…

Accountability test for Philippines’ Marcos family as budget scandal widens

A former prominent lawmaker now in hiding has released new videos accusing Philippine President Ferdinand Marcos Jnr’s family of orchestrating massive corruption, escalating a scandal that is fast becoming a test of accountability for one of Southeast Asia’s most politically influential dynasties. Observers told This Week in Asia that although Zaldy Co’s allegations remained unverified and required rigorous fact-checking, they struck at the core of a system where budget power, patronage and… Source link
