Leonardo da Vinci's Painting Skills Faded after He Fainted: Study

Leonardo da Vinci's Painting Skills Faded after He Fainted: Study "Five centuries after his death, during which thousands of scholars have read his works, have discussed his discoveries and have investigated his life from every point of view, there is still a lot to know about Leonardo da Vinci, the 'Renaissance Man'," Dr. Davide Lazzeri, co-author of the new study told Newsweek.

Earth isn’t the only place that “quakes.” Rocky planets and moons regularly experience similar movements, and faults can form between massive chunks of crust on other worlds the same as they can here on Earth. The Moon is one place we know that experiences those kinds of shifts, and new research suggests that it might actually be making the Moon smaller over time.

The study, which was published in Nature Geoscience, explains how the cliffs observed on the Moon’s surface hint at a cooling spell that occurred after the Moon formed. As it cooled, it “shriveled like a raisin,” and large cliffs formed on the surface when the Moon’s crust was compressed. These regions, known as thrust faults, may still be growing today, and the overall size of the Moon may be shrinking as a result.

‘This Is All We Can Afford’: Shrinking Lives in the English Countryside ALSTON, England — It was not until Trevor Robinson received a letter notifying him of a missed appointment at the hospital that he realized he had not spoken to another human being in more than six weeks.

The discovery suggests that the moon is still tectonically active, and raises the possibility that future lunar bases may be vulnerable to shallow moonquakes. The moon ’s thrust faults are a sign that the whole orb is contracting as it loses internal heat, cools and shrinks ; Mercury is undergoing a similar

This revisiting of the data revealed the approximate source of dozens of lunar quakes detected by the instruments.

“We found that a number of the quakes recorded in the Apollo data happened very close to the faults seen in the LRO imagery,” Nicholas Schmerr of the University of Maryland, co-author of the study, said in a statement. “It’s quite likely that the faults are still active today. You don’t often get to see active tectonics anywhere but Earth, so it’s very exciting to think these faults may still be producing moonquakes.”

A new analysis suggests that the moon may still be shrinking today and actively producing moonquakes along these thrust faults. A team of researchers including Nicholas Schmerr, an assistant professor of geology at the University of Maryland, designed a new algorithm to re-analyze seismic.

When that movement occurs, a quake is felt, and in the case of the Moon the continued movement of the plates may indicate that it’s not done shrinking.

The researchers suggest that this is just another of many reasons why mankind should prioritize a revisit of the Moon. Learning more about how the Moon works and the mechanics at play on the surface could teach us a great deal about other planets as well, and help prepare organizations like NASA for trips deeper into space.

On the beaches around Hiroshima, researchers make an amazing discovery 70 years after the atomic bomb .
© Provided by Business Insider Inc The atomic bombings on Hiroshima and Nagasaki by the USA on August 6 and 9, 1945 are unforgettable events in world history. The traces of the catastrophe can still be found in nature around Hiroshima: Geologist Marc de Urreiztieta discovered microscopic objects on the beach of the Motoujina peninsula, not far from Hiroshima, and sent them to his colleague Mario Wannier.
