What is unique about each of these three pentaquarks is that its mass is slightly lower than the sum of its parts—in this case, the masses of the baryon and meson. “The pentaquark didn’t decay by its usual easy, fall-apart process,” Skwarnicki says. “Instead, it decayed by slowly and laboriously rearranging its quarks, forming a narrow resonance.”
The proof-of-concept shows separation of hydrogen and oxygen gas from seawater by making use of electricity. In comparison to existing methods that rely on obtaining hydrogen fuel from purified water, it is very economical.

While changing the test subjects magnetic field was imperceptible to the subject, the brain did respond with a reduction in alpha-waves. This is evidence for human magnetoreception. – https://www.sciencealert.com/your-brain-can-detect-earth-s-magnetic-field-even-though-you-can-t-tell
