Divers discover world's largest underwater cave system filled with Mayan mysteries

Mexican scientists discovered the world’s largest flooded cave system that extends an amazing 216 miles (347 km) and is filled with artifacts. The maze of caves is a major archaeological find that promises to shed light on the mysteries of the Mayan civilization. 

Underwater archaeologist Guillermo de Anda of Mexico's National Institute of Anthropology and History led the Great Maya Aquifer Project (GAM), which has been exploring underwater caves on the Caribbean coastline of the Yucatán Peninsula in Mexico for decades. The region has 358 freshwater flooded cave systems that stretch for over 870 miles (1,400km). 

De Anda explained that their accomplishment has wide-ranging significance:

"This immense cave represents the most important submerged archaeological site in the world," said de Anda. ”It has more than a hundred archaeological contexts, among which are evidence of the first settlers of America, as well as extinct fauna and, of course, the Maya culture."

The current research effort took 10 months and proved that two caves systems - the Sac Actun System and the Dos Ojos caves are actually part of one continuous and, certainly gigantic, cavity in the Earth.

GAM exploration director Robert Schmittner told the Mexican newspaper El Pais how the research team came close a number of times to proving the connection between the two giant cave systems.

"It was like trying to follow the veins within a body,” said Schmittner. “It was a labyrinth of paths that sometimes came together and sometimes separated. We had to be very careful." 

Now that the researchers showed that the two cave mazes are linked, they think another three underwater cave systems can be added to what is already the longest cave labyrinth in the world.

The impressive caves present an invaluable scientific loot, with divers finding a large amount of Mayan artifacts like ceramics, remains (including those of early humans, giant sloths and tigers) and extinct fauna.

De Anda called the caves a ”tunnel of time that transports you to a place 10,000 to 12,000 years ago."

The “new normal” paradox: What COVID-19 has revealed about higher education

Higher education faces challenges that are unlike any other industry. What path will ASU, and universities like ASU, take in a post-COVID world?

  • Everywhere you turn, the idea that coronavirus has brought on a "new normal" is present and true. But for higher education, COVID-19 exposes a long list of pernicious old problems more than it presents new problems.
  • It was widely known, yet ignored, that digital instruction must be embraced. When combined with traditional, in-person teaching, it can enhance student learning outcomes at scale.
  • COVID-19 has forced institutions to understand that far too many higher education outcomes are determined by a student's family income, and in the context of COVID-19 this means that lower-income students, first-generation students and students of color will be disproportionately afflicted.

Creativity: The science behind the madness

Human brains evolved for creativity. We just have to learn how to access it.

Creativity: The science behind the madness | Rainn Wilson, David Eagleman, Scott ...
Videos
  • An all-star cast of Big Thinkers—actors Rainn Wilson and Ethan Hawke; composer Anthony Brandt; neuroscientists David Eagleman, Wendy Suzuki, and Beau Lotto; and psychologist Scott Barry Kaufman—share how they define creativity and explain how our brains uniquely evolved for the phenomenon.
  • According to Eagleman, during evolution there was an increase in space between our brain's input and output that allows information more time to percolate. We also grew a larger prefrontal cortex which "allows us to simulate what ifs, to separate ourselves from our location in space and time and think about possibilities."
  • Scott Barry Kaufman details 3 brain networks involved in creative thinking, and Wendy Suzuki busts the famous left-brain, right-brain myth.
